Background: Mobile phone addiction and academic procrastination are two common behavioral challenges among adolescents. While prior research has documented their association, the underlying mechanisms-particularly the mediating roles of self-regulation and psychological resilience and the moderating role of the parent-child relationship -remain insufficiently examined.
Methods: This study involved 966 adolescents who completed the Mobile Phone Addiction Scale, Self-Regulation Scale, Brief Resilience Scale, Parent-Child Relationship Scale, and Academic Procrastination Scale-Short Form. Data were analyzed using partial least squares structural equation modeling (PLS-SEM).
Results: The results of the research showed that (1) mobile phone addiction had a significant positive effect on academic procrastination; (2) self-regulation mediated between mobile phone addiction and academic procrasti…

Parent-adolescent relationship quality and smartphone addiction: a hierarchical analysis of relational and demographic predictors.
Background: Adolescents' smartphone use has increased substantially, raising concerns about problematic use and its public health implications. Although parent-child relationship quality plays an important role in adolescents' behavioral regulation, the distinct contributions of parental support and alienation to smartphone addiction remain insufficiently clarified.
Objective: This study examined whether maternal and paternal support and alienation were associated with adolescent smartphone addiction after accounting for demographic characteristics and smartphone use duration.
Methods: A cross-sectional study was conducted among 210 adolescents (aged 11-16 years) from government and government-aided schools in Chennai, India. Participants completed the Smartphone Addiction Scale-Short Version-Tamil (SAS-SV-T) and the mother and father forms of the Inventory of Parent and Peer Attachment …

Moral and rational pathways to pro-environmental behavior among high school students: An integrated TPB-NAM model.
Adolescence is an important period for the development of pro-environmental behavior (PEB), but it remains unclear how subjective norm, personal norm, and perceived behavioral control relate to pro-environmental behavioral intention and self-reported PEB in structured school contexts. This study tested a context-sensitive framework integrating the Theory of Planned Behavior and the Norm Activation Model (TPB-NAM) to explain high school students' PEB. Survey data from 415 high school students in Lanzhou, China, were analyzed using structural equation modeling and mediation analysis. The integrated model showed better overall fit than single-path alternatives and explained substantial variance in intention and self-reported PEB (47.2% and 72.8%, respectively). In the moral pathway, awareness of consequences predicted ascription of responsibility, which predicted personal norm; personal nor…

Forgiveness, Self-Forgiveness, and Child and Adolescent Mental Health: Big Data Findings from an Australian Youth Cohort.
Conflicts and transgressions are inevitable features of the human experience, with well-established negative social, interpersonal, and intrapersonal consequences if they are not adequately resolved. This study tested whether the effectiveness of two adaptive traits typically observed in research with adults—forgiveness and self-forgiveness—would generalize to youth and adolescents, specifically in relation to their psychological wellbeing (hope and life satisfaction) and psychological distress. Notably, the study makes two new contributions: It tests relations with a large nationwide representative sample, and it examines the moderating effects of variables likely to be important considerations in the school context and often where conflict arises, namely school engagement, and student age and gender. There were N = 79,670 participants aged 7–18 years (Mage = 12.05 years; SD = 2.63; mod…

Screen time and manic symptoms in early adolescents: prospective findings from the Adolescent Brain Cognitive Development Study.
Purpose: This study aimed to examine prospective associations between screen time and manic symptoms in early adolescents, and the extent to which problematic screen use (characterized by addiction, conflict, relapse, and withdrawal) mediates the association.
Methods: We analyzed prospective cohort data from the Adolescent Brain Cognitive Development Study (N = 9,243; ages 10-11 years in Year 1 in 2017-2019; 48.8% female; 44.0% racial/ethnic minority). Participants reported daily time spent on six different screen subtypes. Linear regression analyses were used to determine associations between typical daily screen time (Year 1; total and subtypes) and manic symptoms (Year 3, 7 Up Mania scale), adjusting for potential confounders. Sleep duration, problematic social media use, and problematic video game use (Year 2) were tested as potential mediators.
Results: Adjusting for covariates, ove…

Income inequality and adherence to 24-hour movement guideline recommendations among adolescents: a multilevel growth curve analysis using longitudinal data from three waves of the Cannabis, Obesity, Mental health, Physical activity, Sedentary behaviour and Smoking (COMPASS) study (2016-2019).
Background: There is a paucity of literature regarding income inequality and adolescent movement behaviours (physical activity, sedentary behaviours, sleep). This study examined whether income inequality was associated with meeting Canadian 24-Hour Movement Guidelines (24HMG) recommendations among adolescents over time.
Methods: Longitudinal data from adolescents (n=9299) in the Cannabis, Obesity, Mental health, Physical activity, Sedentary behaviour and Smoking study (2016-2017 to 2018-2019) were linked with income data at the census division (CD) level from the 2016 Canadian Census. Adolescents (aged 13-19 years) reported on their physical activity, sleep duration and screen time via questionnaire. Gini coefficients were calculated at the CD level using after-tax household income from the 2016 Canadian Census. Multilevel logistic regression analyses were performed to test the associati…

Discriminatory Climate and School Adjustment in Ethnically Minoritized Adolescents and Majority Adolescents: An Investigation of the Mediating Role of Teaching Quality.
Discriminatory teacher beliefs and behaviors, as reflected in a discriminatory climate, are negatively related to student adjustment, but little is known about the classroom processes contributing to this relationship. This study investigated the role of teaching quality as a mechanism behind the associations between a discriminatory climate at school and students' school adjustment. The study used PISA data collected in Germany in 2018 (N = 2947; Mage = 15.47 years, SD = 0.65; 48.4% girls) and included ninth graders (1) from ethnically minoritized groups that are highly stigmatized (i.e., with heritage from Turkey, the SWANA region, sub-Saharan Africa, and Kurdish areas; n = 198), (2) from other ethnically minoritized groups (n = 445), and (3) from the ethnic majority (n = 2304). The students in Group 1 reported a more discriminatory climate at school than the other student groups did. …

Influence of awe on social responsibility in adolescents and the mediating role of social mindfulness.
Previous research has demonstrated that awe can influence corporate social responsibility; however, the mechanism through which awe affects social responsibility among Chinese adolescents remains unclear. According to the Broaden-and-Build theory of positive emotions, individuals may be prompted to take positive actions, such as enhancing social mindfulness, due to the situational stimuli that evoke their sense of awe. Conversely, these positive actions promote the formation of social responsibility. Thus, the present study aims to explore the impact of awe on adolescents' social responsibility and the mediating role of social mindfulness in this relationship using questionnaire-based and experimental approaches. In Study 1, 1370 adolescents completed the Dispositional Awe Scale, the Social Mindfulness Self-Report Scale and the Social Responsibility Scale. The results revealed that dispo…

Pornography Use and Adolescent Sexual Self-Concept: The Role of Pornography-Related Expectancies and Generalizations.
While researchers have emphasized the need to investigate pornography use in relation to normative or positive aspects of adolescent sexuality and understand differential susceptibility among users, empirical studies remain sparse. In response, this study investigated the link between pornography use and adolescents' sexual self-concept (i.e., sexual self-esteem, body-esteem, sexual anxiety, and self-efficacy). Specifically, it compared the sexual self-concept of adolescents who had used pornography with those who had not, while also examining how frequency of use, pornography-related sexual expectancies, and generalizations were linked to sexual self-concept in a subset of users. A sample of 1584 Canadian adolescents (49.3% cisgender girls; Mage = 15.53 years) completed self-report questionnaires about their sexual functioning. Significant differences in sexual self-concept were found b…

Association Between Smartphone Attachment and Mental Health in Adolescents.
Background: The surge in adolescent smartphone use has coincided with the rise in the adolescent mental health crisis, raising public health concerns. Moving beyond the traditional focus on screen time, this study examined the association between smartphone attachment and mental health among adolescents.
Methods: Data were analyzed from 137 community-dwelling adolescents (aged 16.5-18 years). Smartphone attachment was measured by the Mobile Phone Involvement Questionnaire (MPIQ). Patient Reporting Outcome Measures (PROMIS) pediatric short forms were used to measure anxiety, depression, sleep disturbance, and general health. t-tests and ANOVAs compared anxiety and depression scores between groups above and below the MPIQ threshold for moderate-to-severe attachment. Multivariable regressions estimated associations between smartphone attachment and mental health outcomes, adjusting for demo…

Temporal Patterns of Suicidality Among Adolescents Receiving Behavioral and Mental Health Services in the Community: A Survival Analysis.
Adolescent suicide is a major public health concern, particularly among adolescents who have endured Adverse Childhood Experiences (ACEs). Adolescents who have been exposed to multiple ACEs are as much as three times more likely to present with suicidality compared to the general adolescent population. Adolescents who have been exposed to multiple ACEs are also more likely to receive behavioral and mental health services in the community. It is therefore important to understand patterns of suicidality among this sub-population of adolescents in order to provide the best clinical care. The present study examined the temporal patterns of suicidality among adolescents who have been exposed to multiple ACEs and are receiving behavioral and mental health services in the community. Using Electronic Health Record (EHR) data from a community-based behavioral and mental health care organization, …

Toyoko Kids: A case series on the psychosocial backgrounds of eight runaway girls transported to emergency care in Tokyo.
Aim: Runaway behavior, defined as leaving home without parental permission and not returning, is associated with adverse educational, physical, and mental health outcomes. In Japan, since around 2018, a group of runaway adolescents known as "Toyoko Kids" has emerged in Tokyo's Kabukicho area, reportedly engaging in substance use, violence, and prostitution. This study aimed to examine the psychosocial characteristics of Toyoko Kids who were transported to emergency care due to impaired consciousness from drug overdose or alcohol intoxication.
Methods: We conducted a retrospective chart review of eight female adolescents under 18 years old, transported from Kabukicho to Keio University Hospital between June 2022 and August 2023. Inclusion criteria included having run away for at least two nights (or one night for those under 15) and being transported by a third party. A multidisciplinary …

Awe reduces Chinese adolescents' NSSI urges: The chain-mediating role of meaning in life and ego-depletion, and the moderating role of family function.
Non-suicidal self-injury (NSSI) is a severe psychological crisis among Chinese adolescents, while NSSI urge is a robust predictor of NSSI. Awe, as a positive emotion, may benefit the prevention of NSSI. However, the relationship between awe and NSSI urges is underexplored. This study examined the effect of awe on NSSI urges and its underlying mechanisms among a large sample of Chinese adolescents with a three-wave panel design (with distinct but related constructs measured at each wave). Participants were 969 middle school students from eastern China. The chain mediation model suggested that awe reduces NSSI urges indirectly by sequentially enhancing meaning in life and decreasing ego-depletion. Family function moderated this model, such that the negative predictive effect of awe and the positive predictive effect of ego-depletion on later NSSI urges were stronger when family functioning…

Measuring screen time among adolescents: test-retest reliability of HBSC questionnaire items across two countries.
Background: Increasing recreational screen time among adolescents is linked to adverse health outcomes like obesity and poor mental health. This highlights the need for reliable tools to monitor screen-based behaviours. The present study examined the test-retest reliability of recreational screen-time items from the Health Behaviour in School-aged Children (HBSC) questionnaire across culturally diverse adolescent populations.
Methods: Using a test-retest design with a 2-3 week interval, we collected data from 750 adolescents (48.8% boys, mean age 15.29 years, SD 2.37) in Mexico (n = 233, aged 10-15y) and Czechia (n = 517, aged 10-18y) in 2022-2024. Self-reported time spent on gaming, social networking, video watching, and internet browsing were evaluated using Intraclass Correlation Coefficients (ICCs) for continuous measures and Cohen's kappa for dichotomized outcomes (< 2 vs. ≥ 2 h/day…

The impact of neighborhood environment on adolescent anxiety and depression: A moderated mediation model involving screen time and family function.
Objective: While the relationship between neighborhood environment and adolescent mental health is well-documented, few studies have examined the roles of screen time and family function in this association. This study aims to explore the "environment-behavior-health" pathway by investigating how neighborhood environment, screen time, and family function jointly influence adolescent anxiety and depression.
Method: Data were drawn from a large-scale, two-wave survey of 5th-12th grade Chinese adolescents. A moderated mediation model was constructed to examine whether screen time mediates the relationship between neighborhood environment and adolescent anxiety and depression, and whether this indirect effect is moderated by family function.
Results: The final sample included 8961 Chinese adolescents. Neighborhood environment was negatively associated with adolescents' screen time (b = -0.51…

Associations of 24-hour movement behaviors with emotional and behavioral problems among Chinese adolescents.
Purpose: The role of adherence to the recommendations for 24-hour movement behaviors (24-HMB), including physical activity (PA), screen time (ST), and sleep duration (SLP), in relation to emotional and behavioral problems in Chinese adolescents remains uncertain. This study aimed to investigate these associations and explore potential sex differences.
Methods: This school-based cross-sectional study included 15,071 Chinese adolescents with a mean age of 14.53 (SD: 1.65) years. Data on emotional and behavioral problems and 24-HMB (including PA, ST, and SLP) were collected. Analysis was performed using general linear mixed models, with additional sex-stratified analyses conducted.
Results: The number of 24-HMB recommendations met was negatively associated with total difficulties (β estimate=-0.96, 95% CI: -1.07 to -0.85) and positively related to prosocial behavior (β estimate = 0.41, 95% …

Nurturing Movement: Longitudinal Associations Between Caregiver Type, Adolescent Diet, and Young Adult Physical Activity in a National Cohort.
Background: Childhood obesity rates remain high in the United States, with long-term implications for physical and mental health. Emerging research suggests that caregiving arrangements, particularly those involving non-parental caregivers such as grandparents, may influence adolescent health behaviors, including diet and physical activity. This study examined whether caregiver type (parents-only, grandparents-only, or multi-generational households) during adolescence predicted dietary patterns and physical activity trajectories into young adulthood.
Methods: Data were drawn from 6260 participants in the National Longitudinal Study of Adolescent to Adult Health (Add Health). Caregiver type was identified at baseline (Wave 1), and dietary intake and physical activity were assessed across four waves from adolescence (~age 15) to early adulthood (~age 29).
