Background and objectives: Social network site addiction is strongly correlated with sleep quality among adolescents. However, the underlying mechanisms driving these relationships require further exploration. This study aims to supplement the understanding of the psychological mechanisms linking social network site addiction and sleep quality by investigating depression as a mediating factor and difficulty describing feelings as a moderating factor.

Methods: A self-report survey was conducted with 1,670 adolescents in China, assessing social network site addiction, sleep quality, depression, and difficulty describing feelings. Descriptive and correlational analyses were performed on these variables, followed by the construction of a moderated mediation model.

Results: Social network site addiction was significantly positively correlated with sleep quality, depression, and difficulty describing feelings among adolescents. Difficulty describing feelings was also significantly positively correlated with depression. Depression partially mediated the relationship between social network site addiction and sleep quality, while difficulty describing feelings intensified the relationship between social network site addiction and depression.

Conclusion: This study further elucidates the psychological mechanisms linking social network site addiction and sleep quality in adolescents. Depression acts as a mediating factor, while difficulty describing feelings strengthens the relationship between social network site addiction and depression. These findings highlight the role of difficulty describing feelings in the interplay between social network site addiction and sleep quality, offering valuable insights for a more comprehensive understanding and targeted interventions aimed at improving sleep quality in adolescents.

Web-based interventions have been shown to be effective for various health and mental health problems. However, the effectiveness of interventions is often limited by the fact that individuals do not start or complete them. Using data from an intermediate analysis of the randomized placebo-controlled clinical trial to evaluate the effectiveness of @myTabu, the current study investigated engagement with a web-based intervention for 113 individuals convicted of child sexual abuse and/or for child sexual exploitation material. @myTabu is a human-supported, web-based intervention for individuals who have been convicted for sexual abuse of children or the use of child sexual exploitation material with the goal of reducing the risk factors for recidivism and actual recidivism. The results of the present study indicate that (a) 81% of the participants logged into the web-based intervention within 8 weeks after login credentials were sent; (b) there was a trend toward lower treatment readiness and lower belief in their own technical prerequisites in individuals who did not login; (c) 15% of the participants completed all requested sessions within the first 5 weeks of participation, and the average participant logged in on 6 different days and completed two sessions; (d) the number of login days and completed sessions could be predicted by treatment readiness. We discuss these findings and their implications for the development and implementation of further web-based interventions in the forensic context.

Objective: Guided by Self-System Processes Theory, Social Support Theory, and Stress and Coping Theory, this study investigates how perceived school climate influences adolescents' negative emotions through the chain mediation of school belonging and social avoidance and distress. It also examines demographic differences across gender and grade and tests the structural invariance of the proposed model.

Method: A cross-sectional survey of 1,507 Chinese adolescents in grades 5-9 was conducted using validated scales. Independent samples t-tests and one-way ANOVA were used to examine gender and grade differences in the key variables. Structural equation modeling (SEM) tested the hypothesized mediation model, while multigroup SEM assessed structural invariance across subgroups.

Results: Perceived school climate reduced negative emotions both directly and indirectly, with school belonging and social avoidance and distress as key mediators. Peer support demonstrated the strongest indirect effect, while teacher support and autonomy opportunities influenced negative emotions through both direct and indirect pathways. A chain mediation pathway was identified, and structural invariance testing confirmed consistent relationships across gender and grade groups.

Conclusion: This study reveals a complex chain mediation mechanism and highlights the stability of structural relationships across demographic groups. The findings provide valuable theoretical and practical insights for fostering supportive school environments to promote adolescent emotional well-being.

Individuals with Attention-Deficit/Hyperactivity Disorder (ADHD) often have overlooked motor difficulties which can be at least partially attributed to co-occurring conditions such as Developmental Coordination Disorder (DCD). Understanding the influence of DCD and motor difficulties is important to detect in children for early support. Accordingly, the present study examined the prevalence of DCD diagnoses, cases of probable DCD, and related impairments among German-speaking parents of children with ADHD. A total of N = 168 parents completed an online study about their child's potential for co-occurring DCD via the Developmental Coordination Disorder Questionnaire (DCD-Q). Even after children with DCD diagnoses were removed from the sample (n = 46), a majority still remained below threshold for probable DCD (55.9%) according to parent-reports. Via exploratory analyses, we also found that a majority of parents in the sample had not heard of DCD before (64.9%) and that many parents did not deem DCD as relevant to their children, even when their DCD-Q scores were in the range of probable DCD. The results align with a high prevalence of DCD in children with ADHD despite a simultaneous lack of awareness of DCD. Furthermore, findings in our sample align with frequently estimated global co-occurrence rates of 50% between ADHD and DCD. Broadly, the results support that motor difficulties should be considered in ADHD assessment and intervention.

Background: Fear of missing out (FoMO) is a new type of anxiety disorder in the context of the Internet, which has a negative effects on the physical and mental health and behavior of college students, such as Internet addiction, non-adaptive socializing, and negative emotions. In order to investigate the effect of relative deprivation (RD) on FoMO of college students, this study conducted a moderated mediation model to examine the relationship between RD, FoMO, self-regulatory fatigue (SRF), and personal belief in a just world (BJW).

Methods: A total of 956 college students were surveyed on a RD Questionnaire, SRF Scale, FoMO Scale, and Personal BJW Scale.

Results: The results showed as follows: (1) College students' RD positively predicted FoMO and SRF. (2) SRF partially mediated the link between RD and FoMO. (3) Personal BJW moderated the relationship between RD and FoMO, that is, when personal BJW is high, RD has a stronger predictive effect on SRF.

Conclusion: The results of this study help to reveal the influence and mechanism of RD of college students on FoMO. The results also show that reducing college students' RD, improving self-control ability, and cultivating rational personal BJW can effectively prevent FoMO.

Purpose: To examine the effects of physical activity on college students' social physique anxiety and the mediating and moderating roles of negative physical self and mental toughness in it, and to provide empirical evidence that physical activity improves college students' social physique anxiety.

Methods: Stratified whole cluster convenience sampling was used to survey 1177 university students, 53.8% male and 46.2% female, with a mean age of (19.12 ± 1.21) years. Mediated and moderated effects were analysed using SPSS 26.0 and AMOS 28.0.

Results: (1) Physical activity negatively predicted social physique anxiety (2) Negative physical self and mental toughness (individual power) played a significant partial mediating role between physical activity and social physique anxiety, with mediating effects accounting for 40.09% and 27.11% of the total effect, respectively; (3) The R² change in the interaction term of physical activity and family support in mental toughness (supporting force) reached a significant level, and family support played a significant negative moderating role between physical activity and social physique anxiety, whereas the interaction term of interpersonal assistance and physical activity was not significant and could not moderate the interrelationship between physical activity and social physique anxiety.

Conclusion: Physical activity affects college students' levels of social physique anxiety through negative physical self and mental toughness (individual power); the effect of physical activity on social physique anxiety is negatively moderated by the family support dimension of mental toughness (supporting force).

Background: Fear of cats as a specific phobia disorder can cause disruption in some aspects of the affected people's lives. On the other hand, due to the fact that the two approaches of metacognitive treatment and behavioral therapy methods such as virtual reality are considered common treatment methods in anxiety disorders; It seems that it is necessary to examine the two approaches based on the effectiveness, durability and cost-benefit issue to present and introduce to therapists.

Methods: The present study was a Randomized Clinical Trial study that was conducted on 28 patients with Ailurophobia. Based on simple random sampling, the participants were allocated in two groups: metacognitive intervention and virtual reality intervention. In order to collect data, demographic information questionnaire, cat anxiety questionnaire and researcher-made cat fear questionnaire were used. Data analysis was done with SPSS version 22 software and statistical tests of chi-square, t, analysis of variance. An alpha level of less than 0.05 was considered as a significant level.

Results: The results of the study showed that there was a statistically significant difference between the average anxiety score in the two groups of virtual reality and metacognitive therapy (P˂0.001). So that in the virtual reality group, the anxiety score was significantly reduced. Also, other results of the study indicated that the mean score of the fear of cats scale was significantly lower in the virtual reality group than in the metacognitive therapy group (P˂0.001).

Conclusions: Although both treatment approaches based on virtual reality and metacognition are effective in reducing the level of anxiety and fear of cats in patients with Ailurophobia; However, the effectiveness and continuity of treatment in people receiving virtual reality treatment are more significant.

Different from previous studies on the motives of compensatory consumption, this review focuses on the strategies of compensatory consumption. This literature review aims to introduce two main strategies for compensatory consumption, within-domain and across-domain compensation. Within-domain compensation is a consumption strategy to repair a self-discrepancy in a specific domain, while across-domain compensation refers to a consumption strategy that consumers restore their global self-worth by affirming themselves in other important domains yet unrelated to the self-discrepancies. Based on the SPAR-4-SLR protocol to assemble, arrange and assess literature published from 2008 to 2023 Q1, we chose 65 articles to review. In order to gain a deeper understanding of within-domain and across-domain compensation, we systematically review the existing literature in the field and propose a framework based on the ADO models. Lastly, we discuss the various research directions for within-domain and across-domain compensation from the viewpoint of theory, context, characteristics, and methodology according to the TCCM framework. Researchers, marketers, and advertisers can learn about the latest research related to compensatory consumption strategies in this article.

An ongoing debate on the association between phonological processing and number knowledge concerns the extent to which they influence each other during early childhood. The current study aims to establish the direction of the developmental relationship between these two kinds of abilities at an early age. Eighty-two Chinese kindergarten children were followed from 5 to 6 years old with a one-year interval. We investigated three phonological processing skills (phonological awareness, phonological memory, and rapid automatized naming) and two kinds of basic number knowledge (number identification and number comparison) at time 1 and time 2. Cross-lagged panel analyses revealed that the association between phonological awareness and number comparison was bidirectional. Specifically, early phonological awareness at time 1 could predict later number identification, and early number comparison at time 1 was a significant predictor of later phonological memory. In contrast, rapid automatized naming had no such predictive relations with other variables. The present findings are among the first to provide evidence that basic number knowledge could predict later phonological processing in kindergarten children.

Purpose: The present study aimed to analyze the effectiveness of external and personal regulatory mechanisms in reducing procrastination behavior among university students. For this purpose, the role of teachers' academic motivation is worthwhile in shaping the learning environment and reducing procrastination, with a focus on the mediating roles of emotion regulation and study habits considered imperative.

Research design/method: By employing a quantitative, cross-sectional research design, data were collected from a sample of 210 teachers working in universities located in Multan-Pakistan via convenient sampling, yielding a usable response rate of 70.28%.

Data analysis & study results: The gathered data was analyzed using Smart PLS 4 software. Results from the structural equation model (PLS-SEM) indicated that teachers' academic motivation significantly affects student procrastination. However, when mediated by emotion regulation and study habits, the study confirmed the statistically significant mediating effect of both mediators in mitigating procrastination among students.

Findings: Findings of the present study suggested that enhancing teachers' motivation may be more effective when mediated with emotional regulation and effective study habits. Emotionally regulated students and those with effective study habits were less likely to procrastinate during their academic endeavor. The findings highlighted the need for teacher training programs to develop and promote motivation and support students' emotional and academic regulation to enhance learning outcomes.

Practical implications and recommendations: Based on the above findings, the study suggested that enhancing teacher motivation is more impactful when paired with strategies to foster student emotion regulation and study habits. It also recommended educational policies prioritizing academic content and personalized student engagement strategies to minimize procrastination and promote academic success. Programs should be implemented with a focus on promoting motivation while enabling teachers to support students' emotional and self-regulatory needs for better academic outcomes.
