Psychosocial Determinants of Sleep Behavior and Healthy Sleep Among Adolescents: A Two-Wave Panel Study.

To date, it remains unknown which psychosocial determinants identified by several leading behavior change theories are associated with different sleep parameters among adolescents. Therefore, this study investigates whether changes in knowledge about healthy sleep, attitude toward healthy sleep and going to bed on time, self-efficacy to engage in healthy sleep behavior, perceived parental and peer norms, perceived barriers (e.g., worrying, fear of missing out), and perceived support (e.g., bedtime rules, encouragement) related to healthy sleep are associated with changes in adolescents' sleep duration on school days and free days and sleep quality over a period of 1 year. Two-wave data of 1648 Flemish adolescents (mean age = 15.01, SD = 0.65, 46.3% female) were analyzed using linear models. Increased levels of parental social support, positive attitude towards and perceived advantages of healthy sleep, norm-knowledge, and perceived peer behavior were associated with sleep duration, with parental social support having the strongest association. Increased levels of perceived barriers were associated with decreased levels of sleep quality parameters, and increased levels of self-efficacy, positive attitude, and parental modeling were associated with improved sleep quality parameters, with perceived barriers having the strongest association. The current results indicate that behavior change theories are useful in the context of adolescent sleep behavior and suggest that perceived parental support (i.e., bedtime rules) and perceived barriers are most strongly associated with adolescents' sleep duration and/or quality.

Trajectories of Loneliness During Adolescence Predict Subsequent Symptoms of Depression and Positive Wellbeing.

There is a need to identify the outcomes of changes in loneliness during adolescence, and to consider this within a multidimensional framework of loneliness. This study considered the effects of different trajectories of change in Isolation Loneliness and in Friendship Loneliness upon both positive wellbeing and symptoms of depression. To achieve this, 1782 (43% female; 12.92 years old at the start of the study, SD = 1.60) young people took part in a longitudinal study with four data points across 2 years. Four Isolation Loneliness trajectories and five Friendship Loneliness trajectories were identified. Youth who experienced low levels of Isolation Loneliness that subsequently increased appear to be at particular risk for poor outcomes. Similarly, initially high levels of Friendship Loneliness that decreased rapidly, or which began at a low level and only increased marginally, seem to also be a risk. Loneliness is a multi-dimensional construct and its development during adolescence impacts upon young people's depressive symptomatology and positive mental wellbeing.

A Short-Form Measure of Loneliness to Predict Depression Symptoms Among Adolescents.

The purpose of this study was to produce a short-form measure of loneliness and assesses its prediction of depressive symptoms relative to a comprehensive measure. Western Australian adolescents completed the Friendship Related Loneliness and Isolation subscales of the Perth Aloneness Scale (PALs) three times over 18 months (T 1 n = 1538; T 2, n = 1683; T 3, n = 1406). Items were reduced while preserving predictability. Follow-up confirmatory factor analyses and predictive models with the reduced and full PALs were then tested. A reduced six-item scale (PALs-6) preserved the two-factor structure of the PALs and showed strong prediction of very elevated depressive symptoms (Sensitivity = 0.70, Specificity = 0.78, AUC = 0.81); it was less successful in predicting future symptoms (Sensitivity = 0.67, Specificity = 0.64, AUC = 0.74). The PALs-6 provides a brief measure of adolescent loneliness for clinicians and researchers that also predicts very elevated levels of depression.

Evaluating Mentors in Violence Prevention: A Longitudinal, Multilevel Assessment of Outcome Changes.

There is a need to increase understanding of the effectiveness of bystander programmes targeting gender-based violence in the United Kingdom. There is also a need to utilise a robust theoretical models of decision-making while doing so. Changes were examined in bystanders' attitudes, beliefs, motivations towards intervening, and intervention behavior in situations of gender-based violence. To achieve this, a quantitative examination of Mentors in Violence Prevention was conducted. There were 1396 participants (50% female, 50% male) who were aged 11 to 14 years old (M = 12.25, SD = 0.84) attending high school at the first time point. Participants were attending 17 schools (53% Mentors in Violence Prevention and 47% control) in Scotland. Outcome variables were assessed approximately one year apart using questionnaires. Multilevel linear regressions revealed that Mentors in Violence Prevention did not change outcomes reflecting bystanders' attitudes, beliefs, motivations towards intervening, or intervention behavior in gender-based violence. Discrepancies between the current findings and those of other evaluations may be due to other studies including small numbers of schools that may be more motivated to implement the program. This study also identified two key issues that need to be addressed at stakeholder level before concluding that Mentors in Violence Prevention is ineffective at targeting gender-based violence. That the program has moved towards a more gender-neutral approach in the United Kingdom could explain the null results of this study. Furthermore, the current findings could be attributed to a failure to adequately address the theoretical model underpinning the program in practice.

Adolescents' longitudinal trajectories of mental health and loneliness: The impact of COVID-19 school closures.

INTRODUCTION: Longitudinal research examining the impact of coronavirus disease 2019 (COVID-19) school closures on the mental health of adolescents is scarce. Prolonged periods of physical and social isolation because of such restrictions may have impacted heavily on adolescents' mental health and loneliness. METHODS: The current study addresses a major gap by examining the impact of school closures on the mental health and loneliness of 785, 10- to 17-year-old Western Australian adolescents (mean age = 14.1, SD = 1.31), who were surveyed across four time points: twice before COVID-19, once as schools closed, and once post reopening of schools. Pre- and post-COVID-19 changes in mental health and loneliness were compared using linear mixed models. Random intercept cross-lagged panel models (RI-CLPMs) assessed temporal associations between loneliness, depression symptoms, and positive mental wellbeing. RESULTS: Compared with pre-COVID-19 symptom levels, there were significant increases in depression symptoms, internalizing and externalizing symptoms, and a significant decrease in positive mental wellbeing at different points over time. Symptom change over time differed according to gender and pre-COVID-19 symptom severity. Significant increases in positive attitudes towards being alone and feelings of isolation occurred at different points over time. Gender differences were evident. RI-CLPMs highlighted the predictive significance of friendship quality and having a negative attitude towards being alone over time in relation to depression symptoms. A positive or negative attitude towards being alone was predictive of positive mental wellbeing over time. CONCLUSION: Findings provide evidence that COVID-19-related school closures adversely affected adolescents' mental health and feelings of loneliness.

A Social-Ecological Approach to Understanding Adolescent Sexting Behavior.

This study examined the extent to which active and passive sexting behaviors are associated with family-, school-, peer-, and romantic-level variables. Young people (N = 3,322; 49.1% female, 48.3% male, 2.6% other) aged 11 to 15 years old (M = 12.84, SD = 0.89) took part, and all attended mainstream secondary schools in Scotland. Participants completed self-report measures of school connectedness, parental love and support, perceived susceptibility to peer- and romantic-pressure (e.g., to display behaviors just to impress others), and their involvement in active and passive sexting. The importance of both school- and family-level factors was evident, though perceived romantic-pressure had the largest effect. However, neither school- nor family-level variables were moderated by either perceived romantic-pressure or perceived peer-pressure. Efforts to reduce sexting or increase its safety should primarily seek to tackle young people's ability to respond effectively to romantic-pressure. It may also be helpful to develop school connectedness and to help families provide support that is constructive and not intrusive.

Loneliness in adolescence: a Rasch analysis of the Perth A-loneness scale.

PURPOSE: The psychometric properties of the Perth A-loneness Scale (PALs) have been extensively validated using classical test theory, but to date no studies have applied a Rasch analysis. The purpose of this study was to validate the PALs four subscales, using Rasch analysis. METHODS: Responses from 1484 adolescents (58% female, mean age = 12.8 years), 131 of whom had a diagnosed neurodevelopmental disorder, from 10 Western Australian secondary schools were included in the Rasch analysis. Overall fit, individual item fit, local response dependence, dimensionality, operation of response categories, and differential item functioning (DIF) were examined. RESULTS: The Rasch analysis supported the factor structure of the PALs. A reasonable to high reliability was obtained for each of the subscales. Participants did not distinguish consistently between the higher categories 'very often' and 'always' on three of the subscales. No item showed Differential Item Functioning (DIF) for neurodevelopmental disorder status and age. One item on each of the Positive and Negative Attitude to Aloneness subscales showed DIF for gender. CONCLUSION: The results support the interval scale measurement properties of the PALs and provide clinicians and researchers with a measure to assess adolescent loneliness, a construct strongly associated with a constellation of mental health problems.

Longitudinal relationships between sexting and involvement in both bullying and cyberbullying.

INTRODUCTION: Sexting is a new way to explore sexuality among adolescents that can be associated with bullying behaviors. Previous studies have focused on peer-victimization but relationships between bullying and different forms of sexting have not been explored. This study evaluates the reciprocal relationships between the perpetration of traditional bullying, cyberbullying, and four forms of sexting (sending, receiving, third-party forwarding, and receiving sexts via an intermediary). METHODS: The sample consisted of 1736 Spanish High School students (46.3% female; Mage = 13.60, SD = 1.25). Four direct questions were used to assess sexting, the EBIPQ to measure traditional bullying and the ECIPQ to evaluate cyberbullying. These measures were completed twice, four months apart. A cross-lagged panel analysis evaluated the reciprocal associations of all study measures. RESULTS: Traditional bullying and cyberbullying were positively, reciprocally associated with each other. Generally, those young people who engaged in sexting at T1 were more likely to report engaging in sexting at T2. Third-party forwarding of sexts (forwarding on sexts which have been sent to a young person by others) displays clear relationships with bullying. Young people who reported using traditional bullying behaviours at T1 were more likely to report third-party forwarding of sexual content at T2. Bullies are more likely to later report third-party forwarding of sexts. CONCLUSIONS: A focus on bullying behavior may be important for intervention efforts targeting to prevent possible negative outcomes of engaging in sexting. Recommendations are provided for educational and prevention efforts.

A latent growth curve model to estimate electronic screen use patterns amongst adolescents aged 10 to 17 years.

BACKGROUND: High quality, longitudinal data describing young people's screen use across a number of distinct forms of screen activity is missing from the literature. This study tracked multiple screen use activities (passive screen use, gaming, social networking, web searching) amongst 10- to 17-year-old adolescents across 24 months. METHODS: This study tracked the screen use of 1948 Australian students in Grade 5 (n = 636), Grade 7 (n = 672), and Grade 9 (n = 640) for 24 months. At approximately six-month intervals, students reported their total screen time as well as time spent on social networking, passive screen use, gaming, and web use. Patterns of screen use were determined using latent growth curve modelling. RESULTS: In the Grades 7 and 9 cohorts, girls generally reported more screen use than boys (by approximately one hour a day), though all cohorts of boys reported more gaming. The different forms of screen use were remarkably stable, though specific cohorts showed change for certain forms of screen activity. CONCLUSION: These results highlight the diverse nature of adolescent screen use and emphasise the need to consider both grade and sex in future research and policy.

A prospective investigation of rumination and executive control in predicting overgeneral autobiographical memory in adolescence.

The CaR-FA-X model (Williams et al., 2007), or capture and rumination (CaR), functional avoidance (FA), and impaired executive control (X), is a model of overgeneral autobiographical memory (OGM). Two mechanisms of the model, rumination and executive control, were examined in isolation and in interaction in order to investigate OGM over time. Across two time points, six months apart, a total of 149 adolescents (13-16 years) completed the minimal-instruction autobiographical memory test, a measure of executive control with both emotional and nonemotional stimuli, and measures of brooding rumination and reflective pondering. The results showed that executive control for emotional information was negatively associated with OGM, but only when reflective pondering levels were high. Therefore, in the context of higher levels of reflective pondering, greater switch costs (i.e., lower executive control) when processing emotional information predicted a decrease in OGM over time.

Reciprocal Relationships between Trajectories of Depressive Symptoms and Screen Media Use during Adolescence.

Adolescents are constantly connected with each other and the digital landscape through a myriad of screen media devices. Unprecedented access to the wider world and hence a variety of activities, particularly since the introduction of mobile technology, has given rise to questions regarding the impact of this changing media environment on the mental health of young people. Depressive symptoms are one of the most common disabling health issues in adolescence and although research has examined associations between screen use and symptoms of depression, longitudinal investigations are rare and fewer still consider trajectories of change in symptoms. Given the plethora of devices and normalisation of their use, understanding potential longitudinal associations with mental health is crucial. A sample of 1,749 (47% female) adolescents (10-17 years) participated in six waves of data collection over two years. Symptoms of depression, time spent on screens, and on separate screen activities (social networking, gaming, web browsing, TV/passive) were self-reported. Latent growth curve modelling revealed three trajectories of depressive symptoms (low-stable, high-decreasing, and low-increasing) and there were important differences across these groups on screen use. Some small, positive associations were evident between depressive symptoms and later screen use, and between screen use and later depressive symptoms. However, a Random Intercept Cross Lagged Panel Model revealed no consistent support for a longitudinal association. The study highlights the importance of considering differential trajectories of depressive symptoms and specific forms of screen activity to understand these relationships.

Development of the Adolescent Preoccupation with Screens Scale.

BACKGROUND: Although public health concerns have been raised regarding the detrimental health effects of increasing rates of electronic screen use among adolescents, such effects have been small. Instruments currently available tend to be lengthy, have a clinical research focus, and assess young people's screen use on specific screen-based activities (e.g., TV, computer, or internet). None appear to address screen use across a broad range of screens, including mobile devices and screen-based activities. The objective was to develop a new and short self-report scale for investigating adolescents' screen use across all screens and screen-based activities in non-clinical settings. METHODS: The Adolescent Preoccupation with Screens Scale (APSS) was developed over a three stage process. First, a review of the current literature and existing instruments was undertaken and suitable items identified. Second, the draft APSS was piloted with adolescents and item affectivity and discrimination indices were calculated. Third, a cross sectional school based online survey of 1967 Australian adolescents in grades 5 (10 years old), 7 (13 years) and 9 (15 years) from 25 randomly selected schools was conducted. RESULTS: Factor Analysis on a sub-sample of the data (n = 782) and Confirmatory Factor Analysis on the remaining sub-sample (n = 1185), supported a two-factor model. The first factor reflects adolescents' mood management with screen use, and the second reflects a behavioural preoccupation. The measure demonstrated strong invariance across sex and across Grades 5, 7, and 9. Both factors displayed good internal consistency (α = .91 and .87, respectively). Sex and grade differences on both scales were investigated and boys in Grade 5 reported higher levels of both mood management and behavioural preoccupation with screens. There were no sex differences on mood management in Grades 7 and 9, but girls reported higher behavioural preoccupation in both these later grades. CONCLUSION: The APSS provides researchers with a new, brief and robust measure of potentially problematic screen use across a wide array of screens, including mobile devices, so readily accessed during adolescence.

A narrative synthesis of the applicability of the CaR-FA-X model in child and adolescent populations: a systematic review.

The CaR-FA-X model [Williams, J. M. G., Barnhofer, T., Crane, C., Hermans, D., Raes, F., Watkins, E., … Dalgleish, T. (2007). Autobiographical memory specificity and emotional disorder. Psychological Bulletin, 133(1), 122-148. doi: 10.1037/0033-2909.133.1.122 ] is the most prominent and comprehensive model of overgeneral autobiographical memory (OGM) and provides a framework for OGM. The model comprises of three mechanisms, capture and rumination, functional avoidance and impaired executive control. These can independently, or in interaction, account for OGM. This systematic review aims to evaluate the existing research on the CaR-FA-X model, and trauma exposure studies specific to child and adolescent populations. The following databases were searched: "PsychInfo", "PsychArticles", "PubMed", "Web of Science", "Medline", "SCOPUS" and "Embase" for English-language, peer-reviewed papers with samples

Humor style similarity and difference in friendship dyads.

This study assessed the concurrent and prospective (fall to spring) associations between four different humor styles to assess the degree to which stable friendships are characterized by similarity, and to assess whether best friends' humor styles influence each other's later use of humor. Participants were aged 11-13 years, with 87 stable, reciprocal best friend dyads. Self-report assessments of humor styles were completed on both occasions. Results indicated that there was no initial similarity in dyads' levels of humor. However, dyads' use of humor that enhances interpersonal relationships (Affiliative humor) became positively correlated by spring. Additionally, young people's use of this humor style was positively associated with their best friend's later use of the same. No such effects were present for humor which was aggressive, denigrating toward the self, or used to enhance the self. These results have clear implications for theories of humor style development, highlighting an important role for Affiliative humor within stable friendship dyads.

Understanding the Correlates of Face-to-Face and Cyberbullying Victimization Among U.S. Adolescents: A Social-Ecological Analysis.

Using a national sample of 7,533 U.S. adolescents in grades 6-10, this study compares the social-ecological correlates of face-to-face and cyberbullying victimization. Results indicate that younger age, male sex, hours spent on social media, family socioeconomic status (SES; individual context), parental monitoring (family context), positive feelings about school, and perceived peer support in school (school context) were negatively associated with both forms of victimization. European American race, Hispanic/Latino race (individual), and family satisfaction (family context) were all significantly associated with less face-to-face victimization only, and school pressure (school context) was significantly associated with more face-to-face bullying. Peer groups accepted by parents (family context) were related to less cyberbullying victimization, and calling/texting friends were related to more cyberbullying victimization. Research and practice implications are discussed.

Attributions of Stability, Control and Responsibility: How Parents of Children with Intellectual Disabilities View their Child's Problematic Behaviour and Its Causes.

BACKGROUND: Children with intellectual disabilities have high rates of behaviour problems. This study explored parents' causal beliefs and attributions for general problematic child behaviour in children with different aetiologies of intellectual disabilities. MATERIALS AND METHODS: Ten parents of children with intellectual disabilities participated in interviews about their child's problematic behaviour. RESULTS: Thematic analysis using NVivo revealed that parents viewed their child's problematic behaviour not only as caused by the child's intellectual disabilities but also by other causes unrelated to the intellectual disabilities, as well as by aspects of the social environmental context. Some causes were viewed as stable and uncontrollable and others as unstable and controllable. In addition, parents showed a strong sense of responsibility for child behaviour. CONCLUSIONS: Parents of children with intellectual disabilities do not solely interpret their child's problematic behaviour through the intellectual disabilities but incorporate the environment and causes and attributions that are not related to the intellectual disabilities, which may help to promote more effective parenting.

Virtually impossible: limiting Australian children and adolescents daily screen based media use.

BACKGROUND: Paediatric recommendations to limit children's and adolescents' screen based media use (SBMU) to less than two hours per day appear to have gone unheeded. Given the associated adverse physical and mental health outcomes of SBMU it is understandable that concern is growing worldwide. However, because the majority of studies measuring SBMU have focused on TV viewing, computer use, video game playing, or a combination of these the true extent of total SBMU (including non-sedentary hand held devices) and time spent on specific screen activities remains relatively unknown. This study assesses the amount of time Australian children and adolescents spend on all types of screens and specific screen activities. METHODS: We administered an online instrument specifically developed to gather data on all types of SBMU and SBMU activities to 2,620 (1373 males and 1247 females) 8 to 16 year olds from 25 Australian government and non-government primary and secondary schools. RESULTS: We found that 45% of 8 year olds to 80% of 16 year olds exceeded the recommended < 2 hours per day for SBMU. A series of hierarchical linear models demonstrated different relationships between the degree to which total SBMU and SBMU on specific activities (TV viewing, Gaming, Social Networking, and Web Use) exceeded the < 2 hours recommendation in relation to sex and age. CONCLUSIONS: Current paediatric recommendations pertaining to SBMU may no longer be tenable because screen based media are central in the everyday lives of children and adolescents. In any reappraisal of SBMU exposure times, researchers, educators and health professionals need to take cognizance of the extent to which SBMU differs across specific screen activity, sex, and age.

They made you perfect: A test of the Social Reaction Model of Perfectionism.

Perfectionism serves as a mediator in the relationship between difficult life experiences and psychological distress, but to date no research has examined the effect of recalled peer victimization on perfectionism and adult depressive symptomatology (DS). The present study assessed the Social Reaction Model of Perfectionism (SRMP; Flett, Hewitt, Oliver, & Macdonald (2002b). Perfectionism in children and their parents: A developmental analysis. In G. L. Flett and P. L. Hewitt (Eds.), Perfectionism: Theory, research, and treatment (pp. 89-132). Washington: American Psychological Association), which proposes that perfectionism (self-oriented, other-oriented and socially prescribed perfectionism) results from harsh experiences. This may include experiences of peer victimization (physical, verbal and indirect). The model was extended to also include adult DS and rumination (brooding and reflection). Self-report questionnaires measuring recalled childhood experiences of peer victimization (Owens, Daly, & Slee (2005). Aggressive Behavior, 31, 1-12. doi: 10.1002/ab.20045), current trait perfectionism (Hewitt & Flett (1991). Journal of Personality and Social Psychology, 60, 456-470. http://dx.doi.org/10.1037//0022-3514.60.3.456), rumination (Nolen-Hoeksema & Morrow (1991). Journal of Personality and Social Psychology, 61, 115-121. doi: 10.1037/0022-3514.61.1.115) and DS (Radloff (1977). Applied Psychological Measurement, 1, 386-401. http://dx.doi.org/10.1177/014662167700100306) were completed by 338 adult participants (54% female). Path-analyses revealed recalled indirect victimization to be associated with adults' self-oriented and socially prescribed perfectionism. However, only socially prescribed perfectionism mediated the relation between recalled indirect victimization and adult DS. Brooding rumination also mediated the effect of socially prescribed perfectionism upon DS. The findings support the SRMP, and extend the theory to include the effects of perfectionism on rumination and DS.

Examining mental health correlates of hate-motivated behaviour in Scotland: An investigation of victims, perpetrators and victim-perpetrators.

BACKGROUND: Hate-motivated behaviour (HMB) ranges from microaggressions to criminal acts and is a public health concern with wide-ranging consequences. AIMS: The current study aimed to examine the mental health correlates of HMB perpetration, victimisation and co-occurring victimisation/perpetration. METHODS: Participants (n = 447) completed an online cross-sectional survey assessing demographic factors, HMB (perpetration and victimisation), positive mental wellbeing and symptoms of depression and anxiety. RESULTS: HMB victimisation was associated with lower positive mental wellbeing and increased symptoms of anxiety and depression. However, neither HMB perpetration nor co-occurring perpetration/victimisation were associated with any of the three mental health outcome measures. CONCLUSION: Experiencing HMB as a victim is linked to increased psychological distress. Additional research, which focuses on sampling populations who are known to be at greater risk for involvement in HMB, is needed to fully understand the impact of the victim-offender overlap on mental health outcomes.
