1 Introduction
Sleep quality significantly impacts the physical and mental well-being of adolescents. The invention of electric light in the 19th century marked a pivotal shift in people’s perception of sleep, leading to what can be described as a “sleep war” and disrupting the natural rhythms of daily life (Haig, 2018, p. 87).
According to the China Sleep Research Report (2022) released by the Chinese Sleep Research Society, 67.03% of primary and secondary school students now sleep for 8 hours or less, compared to 62.9% in 2019. This data indicates a growing trend of insufficient sleep in adolescents. These sleep issues not only affect adolescents’ attention, judgment, and memory but also have detrimental effects on their mental health and weaken their immune system, potentially leading to various diseases (Hertenstein et al., 2019; Delrosso et al., 2020; Kansagra, 2020; Narmandakh et al., 2020; Gautam et al., 2021). Given the evolving data and persistent problems, two critical questions arise: Has the “sleep war” truly come to an end? If not, what are the real factors impacting the sleep quality of adolescents?
Previous studies have revealed that adolescents’ sleep quality is influenced by a combination of physiological and social factors. Physiological factors such as sleep apnea, melatonin secretion disorders, and obesity can lead to inadequate sleep. Additionally, social factors play a significant role, including psychological anxiety (Willis and Gregory, 2015; Blake et al., 2018; Zhang L. G. et al., 2023; Zhang Y. et al., 2023), neighborhood environment (Mayne et al., 2021), academic pressure (Sharman and Illingworth, 2019), and social networking (Carvalho-Mendes et al., 2020). With the advancement of internet and media technology, sleep issues have become more complex. Many studies have delved into the intricate relationship between media exposure, problematic internet use, and sleep, particularly focusing on the impact of problematic internet use on adolescent poor sleep quality (Hale et al., 2019; Hamilton et al., 2020; Kortesoja et al., 2023).
Problematic internet use, also known as internet addiction or excessive internet use, can have detrimental effects on the psychological well-being, social behavior, and emotional function of the general public (Salmela-Aro et al., 2016; Yeon-Jin et al., 2018). For adolescents, the allure of the internet’s “dark side” can lead to compulsive and repetitive digital activities, resulting in negative consequences such as anxiety, loneliness, depression, and sleep disorders (Bozoglan et al., 2014; Salmela-Aro et al., 2016; Ranjan et al., 2021). Research indicates that problematic internet use is often associated with increased usage time and its dependency, signifying a chronic lack of self-control and an increased likelihood of insufficient sleep (Vernon et al., 2015). Moreover, prolonged online habits (Higuchi et al., 2005) can lead to excessive stress, stimulating the central nervous system and further compromising sleep quality (Öks et al., 2018; Wang et al., 2022). Additionally, problematic internet use has been linked to a higher incidence of sleep disorders, significantly impacting daily functioning (Wolniczak et al., 2013). In summary, the relationship between problematic internet use and the sleep quality in teenagers is complex and warrants further exploration. Problematic internet use directly impacts the sleep quality of adolescents and has been identified as a precipitating factor influencing anxiety levels in adolescent populations (Thomée et al., 2011). Some scholars have explored how anxiety, in turn, further affects adolescents’ sleep quality (Xiao et al., 2023). While existing research primarily focuses on the causal relationship between problematic internet use and loneliness, and their mutual influence, there is a lack of emphasis on potential mediating and moderating variables between the two.
Problematic internet use can be considered as a stress-precipitating factor leading to poor sleep quality. This study aims to analyze the impact of variables such as problematic internet use on the sleep quality in teenagers, based on the Stressor-Strain-Outcome (SSO) model.
The SSO model comprises three components: stressor, strain, and outcome. It elucidates the relationship between external stress, resulting emotional and physiological reactions, and subsequent negative behaviors (Koeske and Koeske, 1993). Recently, the application of the SSO model has expanded from workplace environments to social media contexts, examining the adverse effects of technological advancements on public behavior (Mick and Fournier, 1998; Cao et al., 2018; Dhir et al., 2018). As the SSO model aligns with the focus of the current study, we propose that problematic internet use (stressor) may lead to anxiety (strain) among teenagers, potentially triggering poor sleep quality (outcome) in this demographic.
This study examines the impact of problematic internet use on adolescents’ anxiety and sleep quality using the SSO (Stimulus-Organism-Response) model as a framework. Our objectives are three-folded. First, testing several research hypotheses related to these variables. Second, elucidating the relationships between problematic internet use, anxiety, and sleep quality in adolescents. Third, provide empirical evidence for the applicability of the SSO model in this context.
H1: Problematic internet use positively predicts anxiety.
H2: Anxiety positively predicts the quality of sleep.
H3: Problematic internet use positively predicts the quality of sleep.
H4: Anxiety plays a mediating role between problematic internet use and sleep quality.
Based on a review of existing research, it is evident that social factors are often examined through the lens of individual behavior and emotions of teenagers. There is an implicit assumption that teenagers can autonomously make decisions about their lives. In the contemporary Chinese society, family plays a fundamental role in shaping adolescents’ daily lives. The collective mindset views family as a “safe haven,” often described metaphorically as “the warm shore for the drifting ship of life,” emphasizing its crucial importance. The family unit profoundly influences an individual’s beliefs and behaviors, catalyzing significant personal transformations (Otani et al., 2017). The intergenerational transmission of values and emotions within families serves as ultimate powerful force in driving changes in individual beliefs and behaviors. This influence extends to various aspects of an individual’s well-being, including psychological states and sleep quality (Hale et al., 2015; Maratia et al., 2023). Family Systems Theory characterized a family as an interconnected system with emotional interaction patterns between generations. This theory views family members as interconnected elements within this system (Janet et al., 1982). Building on this concept, this study aims to incorporate family health into the research model to explore its potential impact on anxiety.
H5: Family health has a moderating effect between problematic internet use and anxiety.
By validating this hypothesis, the study aims to analyze the impact of problematic internet use on teenagers’ sleep quality, based on the SSO theory. Specifically, it seeks to explore the mediating role of anxiety and the moderating role of family health on anxiety. The sleep condition of teenagers, particularly in China, is currently a subject of significant concern (Liang et al., 2021; Chen et al., 2023; Zhang L. G. et al., 2023; Zhang Y. et al., 2023). Therefore, conducting an in-depth study of the factors influencing teenagers’ sleep quality is essential for their healthy development. While cross-sectional studies cannot establish causality, they can provide a theoretical framework for further investigation in longitudinal and randomized intervention studies.
2 Method
2.1 Survey method
This study employed a cross-sectional, face-to-face survey design targeting adolescents aged 12–17 years across mainland China. The survey covered 23 provinces, 5 autonomous regions, and 4 municipalities, encompassing 148 cities, 202 districts/counties, 390 townships/towns/streets, and 780 communities/villages. Hong Kong, Macau, and Taiwan regions were not covered. The sampling procedure utilized a multi-stage stratified approach. Sample size for each province, autonomous region, and municipality was determined based on population proportions derived from the Seventh National Population Census data. Subsequently, stepwise sampling was conducted at the city, district/county, township/town/street, and community/village levels.
A total of 4,500 questionnaires were distributed. Following rigorous validity analysis, 4,265 questionnaires were deemed valid, yielding an effective response rate of 94%. This high response rate enhances the generalizability of our findings to the broader adolescent population in China.
Two rounds of pilot studies were conducted in mid-June and early July 2022, each involving 100 participants. Quota sampling was employed, with quota attributes matching those of the formal survey. These pilot studies informed refinements to the questionnaire, enhancing its comprehension and cognitive accessibility for the target population.
The formal survey was administered via the Wenjuanxing platform. Questionnaires were distributed in a one-on-one, face-to-face format, with participants responding via a provided survey link. Each questionnaire was assigned a unique identifier with the participant’s informed consent. For participants unable to complete the questionnaire independently, survey administrators provided explanations and recorded responses according to the participant’s expressed intentions.
To minimize potential biases during data collection, the following measures were implemented: (1) Strict adherence to research design principles and statistical requirements; (2) Systematic participant registration and coding; (3) Daily briefings for survey administrators to reinforce protocol adherence; (4) Weekly evaluations of collected questionnaires by the research team, addressing issues promptly and ensuring compliance across all survey teams.
Post-collection, two independent researchers conducted back-to-back logical checks and data screening to ensure data integrity. This methodological approach, incorporating pilot studies, refined data collection procedures, and rigorous quality control measures, enhances the reliability and validity of the research findings.
This study adhered to strict ethical guidelines to protect participant anonymity and confidentiality. Prior to data collection, participants were provided with comprehensive information regarding the study’s objectives, methodology, data usage, and confidentiality measures. Informed consent was obtained from all participants, who were required to sign confidentiality agreements. To ensure data protection, we implemented robust anonymization and desensitization processes. All interview records and collected data were securely stored with restricted access. Data usage and sharing were strictly controlled in accordance with the confidentiality agreements.
2.2 Participants
Adolescents were defined as individuals aged 12–19, based on the study’s criteria. Inclusion criteria included being at least 12 years old, possessing Chinese nationality, being a Chinese permanent resident, voluntarily participating in the study, able to complete the online questionnaire independently or with the help of an investigator, and understanding the questionnaire items. Exclusion criteria involved individuals with impaired consciousness or mental disorders, those participating in other similar research projects, and those unwilling to cooperate.
The study conducted an analysis of the respondents’ basic information using SPSS 22.0 statistical software. The analysis, presented in Table 1, revealed that 48% of the respondents were male, while the proportion of female respondents was slightly higher at 52%. The Han nationality represented the overwhelming majority at 89.2%. In terms of occupation, students accounted for 98.4% of the respondents. Education-wise, bachelor’s/associate’s degree and high school/vocational school were the primary categories, representing 45.6 and 32%, respectively. Additionally, in terms of household registration, 54% of the total respondents were urban residents, while 46% were rural residents, with 2,300 and 1965 individuals in each category, respectively.

2.3 Questionnaire design and variable measurement
The process of designing the questionnaire involved several steps. First, a significant amount of relevant literature was collected to determine the research content, understand previous scholars’ questionnaire design, and identify research questions and variables. Second, questions were developed and organized to create the initial questionnaire. Third, a pre-survey test was conducted to assess the questionnaire’s validity and the logic of the questions. Based on the pre-survey results, adjustments were made to finalize the questionnaire for the investigation. The final questionnaire comprised two main parts: the first part focused on demographic variables, including gender, current school stage, household registration, and age, aimed at understanding the general situation of the research participants, especially adolescents. The second part measured various variables (Table 2).
Table 2. Validity analysis of various scales.
2.3.1 Problematic internet use scale
In the assessment of problematic internet use in adolescents, the study utilized the Problematic Internet Use Scale developed by Opakunle et al. (2020). This scale comprises three dimensions and six items, which inquire about various aspects of internet use, such as preference for surfing online over sleeping, feelings of tension when unable to access the internet, attempts to reduce online time, concealment of internet usage, complaints from others about excessive online-surfing time, and feelings of anxiety or tension when offline. These questions assess three areas of problematic internet use: obsession, neglect, and control disorder. Responses were scored on a Likert 5-point scale, ranging from never (0 points) to always (4 points), resulting in a total score range of 0–24 points, with a higher score indicating a more severe degree of problematic internet use among adolescents. In this study, the Cronbach’s α coefficient for this scale was 0.820.
2.3.2 Generalized anxiety disorder 7-item scale
In assessing the level of anxiety in adolescents, the study utilized the GAD-7 scale developed by Spitzer et al. (2006). Each item on the scale is scored on a range of 0–3 points, with a higher total score indicating a higher level of anxiety. Specifically, a GAD-7 score of ≥10 serves as the cutoff value for screening. Scores of 5, 10, and 15 represent varying degrees of anxiety, ranging from mild to moderate to severe. In this study, the Cronbach’s α coefficient for this scale was 0.948.
2.3.3 Short-form family health scale
As a reliable measurement tool, the study employed the Short-Form Family Health Scale to assess the family health status of the respondents (Crandall et al., 2020). This scale consists of 10 items covering four dimensions: external social support, healthy lifestyle, health resources, and social/emotional health. Participants used a 5-point Likert scale (1 = strongly disagree and 5 = strongly agree) to indicate their level of agreement with the family-related statements. Following the recoding of reverse-phrased items, reliability testing was conducted, revealing a Cronbach’s α coefficient of 0.827 in this study, indicating highly reliable measurement results.
2.3.4 B-Pittsburgh sleep quality index scale
The study employed the B-PSQI scale to assess the sleep quality of adolescents. This scale, based on the work of Buysse et al. (1989) and further simplified by Sancho-Domingo et al. (2021), focuses on five dimensions: sleep efficiency, subjective sleep quality, sleep duration, sleep disturbances, and sleep latency (Sancho-Domingo et al., 2021). This streamlined version aims to improve measurement efficiency and applicability by reducing the number of items from 18 to 6 and eliminating two dimensions. Participants used a 4-point Likert scoring guideline, with a higher score indicating poorer sleep quality. The reliability analysis of the questionnaire found that the Cronbach’s α coefficient for this scale in the study was 0.784, indicating highly reliable measurement results.
3 Results
3.1 Validity analysis
Validity analysis aims to assess whether the questions in the questionnaire effectively capture the corresponding indicators or dimensions. It evaluates the reasonableness of the questionnaire’s design and its ability to appropriately reflect the measured variables. Typically, a Kaiser-Meyer-Olkin (KMO) value above 0.7 indicates relatively ideal validity of the scale. Additionally, Bartlett’s test of sphericity is conducted, where a p-value less than 0.05 signifies a significant result. The results of the validity analysis are presented in Table 2. The table shows that the KMO values of all scales exceed 0.7, and the p-values are all less than 0.05, indicating high validity for all questionnaire scales.
3.2 Descriptive statistical analysis
Descriptive statistical analysis is used to investigate the overall distribution of sample data through the analysis of various statistical indicators such as frequency distribution and measures of dispersion. In this study, the key indicators for statistical description were selected based on the actual research objectives, with a focus on frequency and mean. These indicators effectively capture the basic characteristics of the sample in terms of demographic variables and reveal distinct behavioral traits of other variables. This comprehensive analysis provides robust data support for subsequent research.
The detailed results of a descriptive analysis of various respondent variables are presented in Table 3. The analysis indicates that anxiety among adolescents constitutes a significant proportion of 54.2%, with 36.5% experiencing mild anxiety, 11.1% experiencing moderate anxiety, and 4.4% experiencing severe anxiety. These findings highlight the prevalence of anxiety among adolescents, with mild anxiety being the most common type.
Table 3. Descriptive analysis of relevant variables.
The mean total sleep quality score of the sample in this study was 5.78 ± 3.27. According to the Pittsburgh Sleep Quality Index (PSQI) scoring criteria, score exceeding 5 indicate poor sleep quality, with higher scores reflecting more severe sleep disturbances.
Thus, our findings suggest that the average participant in our sample experiences sleep quality issues. Further analysis of specific sleep dimensions revealed concerning trends, particularly regarding sleep duration. A majority of adolescents (57%) reported sleeping less than 7 h per day, which falls below the recommended 8–10 h for this age group (Paruthi et al., 2016).
3.3 Correlation analysis
Correlation analysis is used to measure the strength of the relationship between variables, as indicated by the correlation coefficient. This coefficient reflects both the magnitude and direction of the relationship between two variables. Subsequent data analysis relies on the findings of correlation analysis. In this study, the Pearson coefficient was used to assess correlation and to determine the direction of the relationship, whether positive or negative. Details are presented in Table 4.
Table 4. Correlation coefficient between variables.
The data shows a positive correlation between problematic internet use and family health (r = 0.341, p p p p p p
The analysis revealed moderate positive correlations between problematic internet use and family health, anxiety, and sleep quality. Weak to moderate negative correlations were observed between family health and both sleep quality and anxiety levels. Additionally, a moderate positive correlation was found between anxiety and sleep quality. The moderate nature of these correlations provides valuable insights for future research and intervention strategies. It implies that there is potential for modulation and improvement of these relationships through appropriate interventions and methodologies. This finding opens avenues for developing targeted approaches to address problematic internet use, enhance family health, mitigate anxiety, and improve sleep quality among adolescents.
3.4 Model validation and results
This study utilized the Partial Least Squares method (PLS) within the structural equation model (SEM) framework to empirically test the research hypotheses. PLS, as a second-generation data analysis technique, offers significant advantages. It does not require data to follow a normal distribution nor imposes strict requirements on sample size. Importantly, PLS is well-suited for exploratory research and testing of new models and theories, allowing for in-depth exploration of emerging phenomena. Given the exploratory nature of research on the impact of problematic internet use on sleep quality, this study believes that the PLS method can better meet the research needs. Therefore, the Smart PLS 4.0 statistical software was employed in this study, and a bootstrapping program with 2,000 samples was run to accurately calculate the path coefficients between constructs. This approach not only enhances the study’s accuracy but also provides robust support for further uncovering the relationship between problematic internet use and sleep quality.
3.4.1 Analysis of structural equation modeling
Figure 1 presents the results of the Smart PLS 4.0 analysis of the theoretical model. The findings reveal that the structural equation model, including control variables, explains 9.4% of anxiety and 13.1% of sleep quality, indicating strong explanatory power for our theoretical model. Moreover, the path analysis results confirm the direct effects as hypothesized. Specifically, problematic internet use significantly positively predicts anxiety (β = 0.132, p β = 0.362, p

3.4.2 Testing the mediating effect of anxiety
After comparing the Bootstrapping mediation analysis method and the bias-corrected percentile Bootstrapping mediation analysis method (Zhao et al., 2010), this study integrated previous research (Chin et al., 2003) and adopted the Bootstrapping mediation analysis method in SmartPLS 4.0 to conduct the mediation effect test. The test requirement is that 0 should not fall within the 95% confidence interval of the indirect effect, indicating a significant mediating effect; otherwise, the mediating effect is not significant. As can be seen from Table 5, 0 is not within the confidence interval of this bias correction. Therefore, it can be considered that anxiety has a mediating role in the impact of problematic Internet use on adolescents’ sleep quality. Thus, Hypothesis 4 is validated (Figure 2).

3.4.3 Test of moderating effect of family health
This study utilized Cohen’s ƒ2 to explore the moderating effect of family health on the relationship between problematic internet use and sleep quality. The ƒ2 value was calculated by comparing the explained variance between models with and without the interaction term. A large moderating effect was indicated when ƒ2 was greater than 0.35, a moderate effect when ƒ2 ranged between 0.35 and 0.15, a small effect when ƒ2 ranged between 0.15 and 0.02, and no moderating effect when ƒ2 was less than 0.02 (Cohen, 1988, p. 22).
In the relationship between problematic internet use and anxiety, with the addition of the interaction term between problematic internet use and family health, the ƒ2 value was 0.098, and the R2 increased from 0.094 to 0.131, indicating a certain moderating role of family health. To further investigate the moderating effect of family health on problematic internet use and anxiety, a simple slope graph was plotted between problematic internet use and anxiety based on the mean of family health plus or minus one standard deviation. The results revealed that family health significantly weakened the impact of problematic internet use frequency on anxiety. Specifically, under low family health levels, the positive impact of problematic internet use on anxiety was significantly higher than under high family health levels. As a result, Hypothesis 5 was validated (Figure 2).
4 Discussion
Based on the SSO model, this study aims to elucidate the impact of problematic internet use on adolescent sleep quality, and the influence of anxiety and family health on adolescent sleep quality. The research findings indicate that problematic internet use has a detrimental effect on anxiety, leading to a decline in sleep quality. In essence, problematic internet use acts as a stressor, contributing to the generation of negative emotions such as anxiety among adolescents, ultimately resulting in poor sleep quality.
Previous research has predominantly examined the unidirectional impact of anxiety on problematic internet use. Davis’s cognitive-behavioral model of Pathological Internet Use (PIU), for example, proposes anxiety as a contributing factor in the development of PIU (Davis, 2001). Subsequent studies have expanded on Davis’s model, providing evidence that social anxiety, in particular, can precipitate problematic internet use among adolescents and young adults (Chen, 2024; Huan et al., 2014). However, our study differs from these perspectives through rigorous investigation and data analysis. We found that problematic internet use can predict its impact on anxiety. This finding aligns with a limited number of other studies, such as a longitudinal study showing that individuals with problematic internet use are about 2.5 times more likely to experience depressive symptoms compared to those without problematic internet use (Lam and Peng, 2010). Problematic internet use also heightens the risk of anxiety and stress, particularly among adolescents and young people, amplifying their susceptibility to depression and anxiety symptoms. The issues associated with problematic internet use, encompassing obsession, neglect, and control disorders, contribute to heightened anxiety and mental health challenges among adolescents. The stress resulting from these issues exacerbates the erosion of adolescents’ rationality, intensifies self-loss, and obfuscates their genuine needs, ultimately leading to deeper-level anxiety and mental health problems (Moretta and Buodo, 2020; Gioia et al., 2021; Jahan et al., 2021).
We have established a significant positive correlation between anxiety and sleep quality (β = 0.362, p Randler et al., 2016; Lima et al., 2020; Pagano et al., 2023). According to the cognitive model of insomnia, excessive worries, anxiety, fears, and intrusive thoughts can impair sleep quality and worsen insomnia (Harvey, 2002). Tochigi et al. also found that high levels of anxiety and depression in adolescents aged 12 to 18 can delay bedtime, consistent with this model (Tochigi et al., 2016). The state–trait anxiety theory suggests that persistent negative emotions like tension and anxiety can carry over into sleep, contributing to poor sleep quality. This theory also highlights that excessive tension or worry about sleep quality at bedtime can prolong sleep onset and influence sleep quality, corroborating our findings. Our data indicates that students with high anxiety tend to have delayed bedtimes and experience longer sleep onset latency, suggesting that heightened anxiety may lead to poor sleep quality.
Based on these theoretical models and empirical data analysis, we infer that anxiety, as an intrusive thought, is a predisposing factor for insomnia, keeping individuals in a highly aroused state and predisposing them to excessive rumination (You et al., 2021). When individuals fall into depressive emotions, this negative state can lead to difficulties in falling asleep (You et al., 2021). The fear of poor sleep and the struggle to fall asleep when anticipating difficulty falling asleep are common occurrences. At the same time, adolescents with poor sleep quality tend to be overly concerned about their sleep and its consequences, subjectively sensitive to the discrepancy between their sleep status and the significance of tasks, forming negative perceptions of “poor sleep” (Harvey, 2002). Such cognitive biases trigger emotional and physiological changes, ultimately leading to insomnia. In addition, most of the samples selected in this study are students during their academic years, and academic and social anxieties can lead adolescents to pre-sleep rumination (Gong et al., 2024) and have “allergic” reactions that affect their sleep quality.
We have found that problematic internet use significantly and positively predicts the sleep quality of adolescents, with anxiety playing a crucial mediating role in this relationship. The more severe the problematic internet use, the poorer the sleep quality of adolescents. Previous studies have widely recognized that problematic internet use disrupts the balanced operation between the physical body and the natural sleep patterns of adolescents. The short-wavelength light emitted by electronic screens, such as tablets and smartphones, can trick the brain into perceiving it as daytime, inhibiting the production of melatonin and affecting users’ sleep (Chinoy et al., 2018). However, sleep quality and behavior are not solely within the realm of biological research, but also within the purview of psychology, an interdisciplinary field between natural and social sciences. It is increasingly important to establish a cultural normative understanding of sleep from the perspective of media psychology. Research in this area has found that excessive media use before bedtime can misalign users’ perception of time (Chen, 2024), delaying adolescents’ bedtime, triggering cognitive arousal before sleep (Harbard et al., 2016), and potentially causing anxiety related to the “fear of missing out” (Tandon et al., 2022). Combining these factors can potentially form a vicious cycle that impacts adolescents’ sleep quality and overall health (Pagano et al., 2023). Additionally, the sleep disturbance process theory suggests that excessive emotional arousal can significantly impact sleep quality. Some scholars also argue that stress-related hormones, such as cortisol and corticosterone, can disrupt sleep patterns during certain stages of sleep when individuals experience stress (Yan et al., 2010). Our findings further validate the mediating role of anxiety between problematic internet use and adolescents’ sleep quality based on the SSO theory, as indicated by previous studies.
In addition, our research has revealed that family health moderates the impact of problematic internet use on anxiety within the SSO model. Family health encompasses various factors such as external social support, healthy lifestyle, access to health resources, and emotional well-being within the family (Wang et al., 2023). These factors have been identified as protective elements against mental health issues (Cheng et al., 2017). Previous studies have demonstrated that family support can positively influence adolescents’ mental health, offering them a shield during challenging developmental phases (Thomas et al., 2017; Brinksma et al., 2019). Therefore, our inference is that when family members prioritize caring for and supporting each other while maintaining a healthy lifestyle, individuals may reduce their reliance on media, consequently lowering anxiety triggered by problematic internet use. Moreover, high levels of family health may equip family members with better coping mechanisms for anxiety. Effective communication, emotional support, and joint problem-solving within a family environment can help alleviate anxiety. This type of supportive environment contributes to building individuals’ psychological resilience, enabling them to stay composed and level-headed in the face of stress and anxiety. Our study draws from family system theory, particularly the concept of the “triangle,” which illustrates the dynamic interplay between three individuals and its correlation with chronic anxiety (Jakimowicz et al., 2020). Under normal circumstances, a two-person relationship tends to maintain relative stability, with anxiety levels remaining low. However, as anxiety levels escalate, the relationship between the two individuals may experience strain. To address this pressure and anxiety, the involvement of a third party is often necessary, transforming the original two-person relationship into a triangular one. Within the framework of our study, family health serves as this third party, moderating the adverse impact of problematic internet use on adolescent anxiety.
5 Limitation
This study not only contributes to the understanding of the relationship between problematic Internet use, anxiety, and sleep quality but also lays a theoretical foundation for potential practical interventions. However, it is important to note that the study has certain limitations. The data analysis in this article is based on a national cross-sectional survey, so caution is advised when inferring causal relationships. Future studies could consider longitudinal designs to monitor changes in problematic Internet use, anxiety, family health, and sleep quality among adolescents over an extended period.
Additionally, there may be inherent issues with subjective assessments in self-reported measurements. Furthermore, as the family is a complex communication system, it is influenced by various demographic variables such as gender, age, education, and income, as well as different family types. Subsequent research efforts could explore the diverse impacts of various family structures on problematic Internet use, anxiety, and sleep quality among adolescents.
6 Conclusion
Existing literature primarily focuses on public health, with limited studies from the perspective of media psychology. This study explores the internal mechanism of how problematic internet use affects sleep quality using the Stressor-Strain-Outcome (SSO) model. The findings demonstrate a significant correlation and impact of problematic internet use on anxiety and sleep quality. By developing a theoretical model and conducting empirical research, we establish that problematic internet use notably influences individuals’ anxiety. Importantly, it not only directly impacts sleep quality but also indirectly affects it by triggering anxiety. This discovery reveals the intricate relationship between problematic internet use and sleep quality, offering a fresh angle for further research in related fields.
Furthermore, this study is the first to introduce the significant variable of family health into the SSO model and to examine its role in this relationship. The results indicate that when family health levels are high, the adverse impact of problematic internet use on sleep quality is diminished. This suggests that family support plays a crucial role in alleviating the stress caused by problematic internet use. Therefore, parents should endeavor to create a harmonious and nurturing family environment, actively addressing the psychological and emotional challenges brought about by modernity through effective communication, attention to children’s mental health, and thoughtful management of adolescents’ media exposure. This proactive approach will promote the physical and mental well-being of young people, improve their quality of life and sleep, and establish a strong foundation for their healthy development.
The findings of this study demonstrate a degree of universality and generalizability. The observed associations among problematic internet use, anxiety, and sleep quality suggest broader societal implications, offering valuable insights for further exploration in related fields such as psychology, education, and sociology. Family health emerged as a crucial factor in mitigating the negative effects of problematic internet use. The role of family health may transcend diverse cultural backgrounds and age groups, warranting further investigation. Future research could explore how family health moderates the relationship between problematic internet use and sleep quality across various cultural and socioeconomic contexts, as well as different age cohorts. The intervention strategies proposed in this study, including fostering a harmonious family atmosphere, promoting effective communication, and prioritizing children’s mental health, have potential for broad applicability. These strategies may be relevant not only to our study population but also to other families and educational institutions across diverse settings. Implementation of these strategies could help individuals better cope with the challenges posed by problematic internet use, potentially enhancing overall quality of life and psychophysical well-being. However, it is important to note that while these findings suggest broad applicability, cultural and contextual factors may influence the effectiveness of interventions. Further research is needed to validate the efficacy of these strategies across different populations and settings.
