Many longitudinal studies have investigated whether self‐esteem predicts depressive symptoms (vulnerability model) or the other way around (scar model) in adolescents. The most common method of analysis has been the cross‐lagged panel model (CLPM). The CLPM does not separate between‐person effects from within‐person effects, making it unclear whether the results from previous studies actually reflect the within‐person effects or whether they reflect differences between people. We investigated the associations between self‐esteem and depressive symptoms at the within‐person level, using random intercept cross‐lagged panel models (RI‐CLPMs). To get an impression of the magnitude of possible differences between the RI‐CLPM and the CLPM, we compared the results of both models. We used data from three longitudinal adolescent samples (age range: 7–18 years; study 1: N = 1948; study 2: N = 1455; study 3: N = 316). Intervals between the measurements were 1–1.5 years. Single‐paper meta‐analyses showed support for small within‐person associations from self‐esteem to depressive symptoms, but not the other way around, thus only providing some support for the vulnerability model. The cross‐lagged associations in the aggregated RI‐CLPM and CLPM showed similar effect sizes. Overall, our results show that over 1‐ to 1.5‐year time intervals, low self‐esteem may negatively influence depressive symptoms over time within adolescents, but only weakly so. © 2018 The Authors.

Objective To identify the early signs of mood disorder development, specifically bipolar disorder ( BD), in a population at familial risk for BD. Method The sample included 107 Dutch adolescent bipolar offspring (age 12-21) followed into adulthood (age 22-32). Lifetime DSM- IV axis I diagnoses were examined at baseline, 1-, 5-, and 12- year follow-up. Symptoms were assessed at baseline on a 3-point Likert scale at baseline with the K- SADS- PL and were analyzed using symptom and sum scores. As observed in previous studies, BD typically starts with other mood disorders. Therefore, the sample was stratified in offspring with a mood diagnosis ( n = 29) and without ( n = 78) at baseline. Results Subthreshold manic experiences proved the strongest predictor of BD conversion ( n = 10; HR2.16, CI95% 1.23-3.78). At symptom level, elated mood, decreased need of sleep, racing thoughts, suicidal ideation, and middle insomnia were significantly associated with BD conversion. Depressive symptoms proved the strongest predictor for first mood episode onset ( n = 28; HR1.27, CI95% 1.02-1.58). Conclusion This study extends our knowledge of prodromal manifestations of BD in a high-risk population. Although preliminary, findings of this study provide potential targets for early identification and underscore the importance of detailed assessment of manic symptomatology in bipolar offspring.

ABSTRACT: Three studies using independent samples of bereaved individuals were conducted to examine the association of self-concept clarity (SCC) with symptoms of prolonged grief disorder (PGD), a debilitating syndrome than can develop after bereavement. Study 1 (N = 67) showed that lower SCC was associated with greater PGD severity, independent from self-concept content change. Using a retrospective design, Study 2 (N = 116) showed that a loss can coincide with a decline in SCC, the magnitude of which was associated with acute PGD severity. Study 2 also showed that the maintenance of PGD symptoms over time was associated with a smaller increase in SCC beyond the first month of bereavement and not with this acute SCC decline. Using a prospective-longitudinal design, Study 3 (N = 121) showed that the impact of lower SCC on concurrent and prospective PGD severity was mediated by lower self-esteem, depressive avoidance, and rumination. Moreover, lower initial SCC predicted PGD severity 6 months later. [ABSTRACT FROM AUTHOR]

ABSTRACT: This study investigated the factor-structure of retrospectively assessed peritraumatic dissociation in the moments surrounding the death of a loved one and concurrent and prospective associations of such peritraumatic dissociation with loss-related emotional distress. Data were available from 168 people, bereaved in the preceding year. They completed the Peritraumatic Dissociative Experiences Questionnaire with their loss as the index event, together with measures of prolonged grief disorder, depression, and posttraumatic stress disorder; 117 completed symptom measures again 1 year later. Confirmatory factor analysis comparing the fit of four competing models showed that the eight-item one-factor model found in the first study using the Peritraumatic Dissociative Experiences Questionnaire provided the best fit to the data. Peritraumatic dissociation predicted concurrent and prospective symptom levels even when controlling for neuroticism and demographic and loss-related variables. [ABSTRACT FROM AUTHOR]

Introduction: Health behaviours such as exercise and diet strongly influence well-being and disease risk, providing the opportunity for interventions tailored to diverse individual contexts. Precise behaviour interventions are critical during adolescence and young adulthood (ages 10-25), a formative period shaping lifelong well-being. We will conduct a systematic review of just-in-time adaptive interventions (JITAIs) for health behaviour and well-being in adolescents and young adults (AYAs). A JITAI is an emerging digital health design that provides precise health support by monitoring and adjusting to individual, specific and evolving contexts in real time. Despite demonstrated potential, no published reviews have explored how JITAIs can dynamically adapt to intersectional health factors of diverse AYAs. We will identify the JITAIs' distal and proximal outcomes and their tailoring mechanisms, and report their effectiveness. We will also explore studies' considerations of health equity. This will form a comprehensive assessment of JITAIs and their role in promoting health behaviours of AYAs. We will integrate evidence to guide the development and implementation of precise, effective and equitable digital health interventions for AYAs., Methods and Analysis: In adherence to Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines, we will conduct a systematic search across multiple databases, including CENTRAL, MEDLINE and WHO Global Index Medicus. We will include peer-reviewed studies on JITAIs targeting health of AYAs in multiple languages. Two independent reviewers will conduct screening and data extraction of study and participant characteristics, JITAI designs, health outcome measures and equity considerations. We will provide a narrative synthesis of findings and, if data allows, conduct a meta-analysis., Ethics and Dissemination: As we will not collect primary data, we do not require ethical approval. We will disseminate the review findings through peer-reviewed journal publication, conferences and stakeholder meetings to inform participatory research., Prospero Registration Number: CRD42023473117., Competing Interests: Competing interests: ET is employed by Gro-up, a non-profit organisation in the Netherlands promoting the well-being of children and youth and their families.

Our society faces a great diversity of opportunities for youth. The 10-year Growing Up Together in Society (GUTS) program has the long-term goal to understand which combination of measures best predict societal trajectories, such as school success, mental health, well-being, and developing a sense of belonging in society. Our leading hypothesis is that self-regulation is key to how adolescents successfully navigate the demands of contemporary society. We aim to test these questions using socio-economic, questionnaire (including experience sampling methods), behavioral, brain (fMRI, sMRI, EEG), hormonal, and genetic measures in four large cohorts including adolescents and young adults. Two cohorts are designed as test and replication cohorts to test the developmental trajectory of self-regulation, including adolescents of different socioeconomic status thereby bridging individual, family, and societal perspectives. The third cohort consists of an entire social network to examine how neural and self-regulatory development influences and is influenced by whom adolescents and young adults choose to interact with. The fourth cohort includes youth with early signs of antisocial and delinquent behavior to understand patterns of societal development in individuals at the extreme ends of self-regulation and societal participation, and examines pathways into and out of delinquency. We will complement the newly collected cohorts with data from existing large-scale population-based and case-control cohorts. The study is embedded in a transdisciplinary approach that engages stakeholders throughout the design stage, with a strong focus on citizen science and youth participation in study design, data collection, and interpretation of results, to ensure optimal translation to youth in society., Competing Interests: Declaration of Competing Interest The authors have no competing interests., (Copyright © 2024 The Authors.

Background: Parent-adolescent relationship quality is theorized to be an important correlate of adolescent affective well-being. Little is known about the within-family processes underlying parent-adolescent relationship quality and affective well-being over a period of months. This three-wave, preregistered study examined within- and between-family associations between parent-adolescent relationship quality (support and conflict) and adolescent well-being (negative and positive affect). In addition, we examined whether the associations differed between mothers and fathers, and for adolescents' affective well-being in different social contexts (at home, at school, with peers)., Methods: The sample consisted of 244 Dutch adolescents (61.5% girls; age range: 12-17 years; mean age = 13.8 years). Random-intercept cross-lagged panel models were used., Results: At the between-family level, higher levels of support and lower levels of conflict were associated with higher levels of positive affect and lower levels of negative affect. At the within-family level, increases in support and decreases in conflict were concurrently associated with increases in positive affect and decreases in negative affect. More parent-adolescent conflict than typical also predicted increases in negative affect, 3 months later, and more negative affect and less positive affect than typical predicted increased conflict, 3 months later. These within-family effects were largely similar for fathers and mothers. Associations for conflict occurred through bidirectional processes: Parent-adolescent conflict shaped and was shaped by adolescents' emotions at home, at school, and with peers., Conclusion: Results suggest that parent-adolescent relationship quality (especially conflict) and adolescent affective well-being cofluctuate and predict each other over time within families., (© 2024 The Authors.

Mobile Health (mHealth) interventions have the potential to improve early identification, prevention, and treatment of mental health problems. Grow It! is a multiplayer smartphone app designed for youth aged 12-25, allowing them to monitor their emotions and engage in daily challenges based on Cognitive Behavioral Therapy (CBT) principles. Recently, a personalized mood profile was added to improve the app. We investigated whether real-time personalized feedback on mood enhances app engagement, user experience, and the effects on affective and cognitive well-being. Sample A ( N  = 1269, age = 18.60 SD = 3.39, 80.6% girls, 95.4% Dutch) played the original app without feedback on their mood, and an independent Sample B ( N  = 386, age = 16.04 SD = 3.21, 67.6% girls, 82.9% Dutch) received the renewed version with personalized real-time feedback on their mood. Participants who received personal feedback did not have higher app engagement ( t (1750,400) = 1.39, P  = .206, d  = 0.07; t (692,905) = 0.36, P  = .971, d  = 0.0) nor higher user experience ( t (177,596) = 0.21, P  = .831, d  = 0.02; ( t (794) = 1.28, P  = .202, d  = 0.12; χ 2 (659,141) = 2.83, P  = .091). Players of the renewed version (Sample B) experienced significant improvements in affective ( t (175) = 3.01, P =  .003, d  = 0.23) and cognitive well-being ( t (175) = 3.48, P  = <.001, d  = 0.26) over the course of three weeks. The renewed version Grow It! has the potential to enhance youths' affective and cognitive well-being. However, adding real-time insights did not seem to affect app engagement nor user experience., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

According to environmental sensitivity models, children vary in responsivity to parenting. However, different models propose different patterns, with responsivity to primarily: (1) adverse parenting (adverse sensitive); or (2) supportive parenting (vantage sensitive); or (3) to both (differentially susceptible). This preregistered study tested whether these three responsivity patterns coexist. We used intensive longitudinal data of Dutch adolescents ( N = 256, M age = 14.8, 72% female) who bi-weekly reported on adverse and supportive parenting and their psychological functioning ( t mean = 17.7, t max = 26). Dynamic Structural Equation Models (DSEM) indeed revealed differential parenting effects. As hypothesized, we found that all three responsivity patterns coexisted in our sample: 5% were adverse sensitive, 3% vantage sensitive, and 26% differentially susceptible. No adolescent appeared unsusceptible, however. Instead, we labeled 28% as unperceptive, because they did not perceive any changes in parenting and scored lower on trait environmental sensitivity than others. Furthermore, unexpected patterns emerged, with 37% responding contrary to parenting theories (e.g., decreased psychological functioning after more parental support). Sensitivity analyses with concurrent effects and parent-reported parenting were performed. Overall, findings indicate that theorized responsivity-to-parenting patterns might coexist in the population, and that there are other, previously undetected patterns that go beyond environmental sensitivity models.

Numerous theories suggest that parents and adolescents influence each other in diverse ways; however, whether these influences differ between subgroups or are unique to each family remains uncertain. Therefore, this study explored whether data-driven subgroups of families emerged that exhibited a similar daily interplay between parenting and adolescent affective well-being. To do so, Subgrouping Group Iterative Multiple Model Estimation (S-GIMME) was used to estimate family-specific dynamic network models, containing same- and next-day associations among five parenting practices (i.e., warmth, autonomy support, psychological control, strictness, monitoring) and adolescent positive and negative affect. These family-specific networks were estimated for 129 adolescents (M age  = 13.3, SD age  = 1.2, 64% female, 87% Dutch), who reported each day on parenting and their affect for 100 consecutive days. The findings of S-GIMME did not identify data-driven subgroups sharing similar parenting-affect associations. Instead, each family displayed a unique pattern of temporal associations between the different practices and adolescent affect. Thus, the ways in which parenting practices were related to adolescents' affect in everyday life were family specific., (© 2023. The Author(s).)

Adolescents spend a substantial portion of their time using social media. Yet, there is a lack of understanding regarding how often parents and adolescents communicate about this social media use. To address this gap, we developed the Parent-Adolescent Communication about Adolescents' Social Media Use Scale (PACAS). In a first data wave, among 388 Dutch adolescents (13-15 years; 54% girls), exploratory and confirmatory factor analyses distinguished four scales: parental solicitation, adolescent disclosure, adolescent secrecy, and parental knowledge. All four scales had strong internal reliability and correlated in the expected directions. We re-established the validity and internal reliability and obtained test-retest reliability in a second wave, in which 330 adolescents were surveyed again. The findings show that parents and adolescents infrequently communicate about social media. Parental knowledge about adolescents' social media use strongly depends on the communication efforts of both parties. Altogether, the PACAS provides a valuable tool to explore the dynamics of parent-adolescent communication about social media., Competing Interests: No potential conflict of interest was reported by the author(s)., (© 2024 The Author(s).

This preregistered longitudinal study examined changes in adolescents' depressive and anxiety symptoms before and during the COVID-19 pandemic using latent additive piece-wise growth models. It also assessed whether support from and conflict with mothers, fathers, siblings, and best friends explained heterogeneity in change patterns. One hundred and ninety-two Dutch adolescents (Mean age: 14.3 years; 68.8% female) completed online biweekly questionnaires for a year (November 2019-October 2020), consisting of a prepandemic, lockdown, and reopening phase. Depressive symptoms increased following the lockdown and decreased upon reopening. Anxiety symptoms showed an immediate decrease followed by a gradual increase in the reopening phase. Prepandemic family and best friend support and conflict did not explain heterogeneity in depressive and anxiety symptoms during the COVID-19 pandemic., (© 2023 The Authors.

This experience sampling study examined whether autonomy-supportive and psychologically controlling interactions with parents are intertwined with adolescents' momentary affect. For 7 days (in 2020), 143 adolescents (M age  = 15.82; SD age  = 1.75; 64% girls; 95% European, 1% African, 3% unknown) reported 5 or 6 times a day how they felt and how interactions with parents were experienced. Preregistered dynamic structural equation models on 1439 (including 532 adjacent) parent-adolescent interactions revealed significant within-family associations: Adolescents experienced more positive affect during and following autonomy-supportive interactions, and vice versa. Adolescents felt more negative affect during and 3 h before psychologically controlling interactions. Between-family associations showed significant linkages between parenting and affect. These findings show that a moment of autonomy support can alter adolescents' everyday well-being., (© 2023 The Authors.

Transactional processes between parental support and adolescents' depressive symptoms might differ in the short term versus long term. Therefore, this multi-sample study tested bidirectional within-family associations between perceived parental support and depressive symptoms in adolescents with datasets with varying measurement intervals: Daily ( N = 244, M age = 13.8 years, 38% male), bi-weekly ( N = 256, M age = 14.4 years, 29% male), three-monthly ( N = 245, M age = 13.9 years, 38% male), annual ( N = 1,664, M age = 11.1 years, 51% male), and biennial ( N = 502, M age = 13.8 years, 48% male). Preregistered random-intercept cross-lagged panel models (RI-CLPMs) showed negative between- and within-family correlations. Moreover, although the preregistered models showed no within-family lagged effect from perceived parental support to adolescent depressive symptoms at any timescale, an exploratory model demonstrated a negative lagged effect at a biennial timescale with the annual dataset. Concerning the reverse within-family lagged effect, increases in adolescent depressive symptoms predicted decreases in perceived parental support 2 weeks and 3 months later (relationship erosion effect). Most cross-lagged effects were not moderated by adolescent sex or neuroticism trait level. Thus, the findings mostly support adolescent-driven effects at understudied timescales and illustrate that within-family lagged effects do not generalize across timescales.

Numerous theories and empirical studies have suggested that parents and their adolescent children reciprocally influence each other. As most studies have focused on group-level patterns, however, it remained unclear whether this was true for every family. To investigate potential heterogeneity in directionality, we applied a novel idiographic approach to examine the effects between parenting and adolescent well-being in each family separately. For 100 days, 159 Dutch adolescents (M age  = 13.31, 62% female) reported on affective well-being and four parenting dimensions. The family-specific effects of pre-registered ( https://osf.io/7n2jx/ ) dynamic structural equation models indeed revealed that a reciprocal day-to-day association between parenting and adolescent affective well-being was present only in some families, with the proportion of families displaying a reciprocal association varying across the four parenting dimensions (11-55%). In other families, either parenting predicted the adolescent's affective well-being (8-43%) or vice versa (10-27%), or no day-to-day associations were found (16-60%). Adolescents with higher trait levels of environmental sensitivity and neuroticism were more strongly affected by parenting. Thus, findings suggest that the ways in which parents and adolescents influence each other in everyday life are unique, stressing the need to move towards an idiographic parenting science., (© 2023.

Although parental overprotection is theorized to have lasting negative effects throughout a child's life, there is limited empirical evidence available on its long-term significance on adolescent well-being. This preregistered, three-wave longitudinal study investigated the association of maternal and paternal perceived overprotection in early adolescence with the development of (mal)adaptive psychological, academic, and social functioning throughout adolescence. Data (N = 2229; 50.7% girls) from the longitudinal TRacking Adolescents' Individual Lives Survey (TRAILS) in the Netherlands were used (M age T1 = 11.11, T2 = 13.57, T3 = 16.28). At T1, adolescents reported on their mothers' and fathers' overprotection. From T1 to T3 adolescents and teachers reported about internalizing problems, academic achievement, prosocial, and antisocial behavior. The results showed concurrent associations between higher levels of perceived overprotection and higher levels of internalizing problems, antisocial behaviors, and (after controlling for parental warmth and rejection) lower levels of academic achievement. Perceived overprotection was positively associated with decreased internalizing problems over time. This longitudinal association disappeared after controlling for baseline levels of internalizing problems, suggesting that this result was less robust than expected. Mothers and fathers did not differ in their associations between perceived overprotection and (mal)adaptive functioning. The findings showed that perceived overprotection is mainly concurrently associated with (mal)adaptive adolescent functioning. Future research recommendations are discussed in terms of stability and bidirectional relations., (© 2023. The Author(s).)

Background: Stress is an important predictor of mental health problems such as burnout and depression. Acute stress is considered adaptive, whereas chronic stress is viewed as detrimental to well-being. To aid in the early detection of chronic stress, machine learning models are increasingly trained to learn the quantitative relation from digital footprints to self-reported stress. Prior studies have investigated general principles in population-wide studies, but the extent to which the findings apply to individuals is understudied., Objective: We aimed to explore to what extent machine learning models can leverage features of smartphone app use log data to recognize momentary subjective stress in individuals, which of these features are most important for predicting stress and represent potential digital markers of stress, the nature of the relations between these digital markers and stress, and the degree to which these relations differ across people., Methods: Student participants (N=224) self-reported momentary subjective stress 5 times per day up to 60 days in total (44,381 observations); in parallel, dedicated smartphone software continuously logged their smartphone app use. We extracted features from the log data (eg, time spent on app categories such as messenger apps and proxies for sleep duration and onset) and trained machine learning models to predict momentary subjective stress from these features using 2 approaches: modeling general relations at the group level (nomothetic approach) and modeling relations for each person separately (idiographic approach). To identify potential digital markers of momentary subjective stress, we applied explainable artificial intelligence methodology (ie, Shapley additive explanations). We evaluated model accuracy on a person-to-person basis in out-of-sample observations., Results: We identified prolonged use of messenger and social network site apps and proxies for sleep duration and onset as the most important features across modeling approaches (nomothetic vs idiographic). The relations of these digital markers with momentary subjective stress differed from person to person, as did model accuracy. Sleep proxies, messenger, and social network use were heterogeneously related to stress (ie, negative in some and positive or zero in others). Model predictions correlated positively and statistically significantly with self-reported stress in most individuals (median person-specific correlation=0.15-0.19 for nomothetic models and median person-specific correlation=0.00-0.09 for idiographic models)., Conclusions: Our findings indicate that smartphone log data can be used for identifying digital markers of stress and also show that the relation between specific digital markers and stress differs from person to person. These findings warrant follow-up studies in other populations (eg, professionals and clinical populations) and pave the way for similar research using physiological measures of stress., (©George Aalbers, Andrew T Hendrickson, Mariek MP Vanden Abeele, Loes Keijsers.

Introduction: The corona virus (COVID-19) pandemic may have a prolonged impact on people's lives, with multiple waves of infections and lockdowns, but how a lockdown may alter emotional functioning is still hardly understood., Methods: In this 100-daily diaries study, we examined how to affect intensity and variability of adolescents (N = 159, M age  = 13.3, 61.6% female) and parents (N = 159, M age  = 45.3, 79.9% female) changed after the onset and during (>50 days) the second COVID-19 lockdown in the Netherlands, using preregistered piecewise growth models., Results: We found only an unexpected increase in parents' positive affect intensity after the lockdown onset, but no immediate changes in negative affect intensity or variability. However, both adolescents and parents reported gradual increases in negative affect intensity and variability as the lockdown prolonged. Lockdown effects did not differ between adolescents and parents. However, within groups, individuals differed. The individual differences in the effects were partly explained by life satisfaction, depressive symptoms, and self-reported lockdown impact., Conclusions: Overall, these findings suggests that a lockdown triggers changes in daily affective well-being especially as the lockdown prolongs. Individual differences in the effects indicate heterogeneity in the impact of the lockdown on daily affect that was partly explained by baseline life satisfaction and depressive symptoms. However, more knowledge on the causes of this heterogeneity is needed to be able to increase resilience to lockdown effects in the population., (© 2022 The Authors.

Adolescents are at increased risk for developing mental health problems. The Grow It! app is an mHealth intervention aimed at preventing mental health problems through improving coping by cognitive behavioral therapy (CBT)-inspired challenges as well as self-monitoring of emotions through Experience Sampling Methods (ESM). Yet, little is known about daily changes in well-being and coping during a stressful period, like the COVID-19 pandemic. The current study aimed to elucidate daily changes in positive and negative affect, and adaptive coping, and to better understand the within-person's mechanisms of the Grow It! app. The sample consisted of 12-25-year old Dutch adolescents in two independent cohorts (cohort 1: N = 476, Mage = 16.24, 76.1% female, 88.7% Dutch; cohort 2: N = 814, Mage = 18.45, 82.8% female, 97.2% Dutch). ESM were used to measure daily positive and negative affect and coping (cohort 1: 42 days, 210 assessments per person; cohort 2: 21 days, 105 assessments). The results showed that, on average, adolescents decreased in daily positive affect and adaptive coping, and increased in their experienced negative affect. A positive relation between adaptive coping and positive affect was found, although independent of the CBT-based challenges. Latent class analysis identified two heterogeneous trajectories for both positive and negative affect, indicating that the majority of participants with low to moderate-risk on developing mental health problems were likely to benefit from the Grow It! app., (© 2022.

Even though each adolescent is unique, some ingredients for development may still be universal. According to Self-Determination Theory, every adolescent's well-being should benefit when parents provide warmth and autonomy. To rigorously test this idea that each family has similar mechanisms, we followed 159 Dutch parent-adolescent dyads (parent: M age  = 45.34, 79% mothers; adolescent: M age  = 13.31, 62% female) for more than three months, and collected 100 consecutive daily reports of parental warmth, autonomy support, positive and negative affect. Positive effects of parental warmth and autonomy support upon well-being were found in 91-98% of the families. Preregistered analysis of 14,546 daily reports confirmed that effects of parenting differed in strength (i.e., some adolescents benefited more than others), but were universal in their direction (i.e., in fewer than 1% of families effects were in an unexpected direction). Albeit stronger with child-reported parenting, similar patterns were found with parent-reports. Adolescents who benefited most from need-supportive parenting in daily life were characterized by higher overall sensitivity to environmental influences. Whereas recent work suggests that each child and each family have unique developmental mechanisms, this study suggests that need-supportive parenting promotes adolescent well-being in most families., (© 2022.

One of the key challenges faced by many parents is to manage the pervasiveness of social media in adolescents' lives and its effects on adolescents' well-being (e.g., life satisfaction) and ill-being (e.g., depressive symptoms). Parents may manage adolescents' social media use and social media-induced well-being and ill-being through media-specific parenting: parental actions to restrict, regulate, and discuss adolescents' social media use. Recent evidence suggests that media-specific parenting may reduce adolescents' anxiety and depressive symptoms and minimize the effects of cyberbullying on adolescents' depressive symptoms. However, more robust evidence regarding the moderating role of media-specific parenting and the direction of effects has to be established to understand how parents may shape the effects of social media on adolescents' well-being and ill-being., Competing Interests: Conflict of interest statement Nothing declared., (Copyright © 2022 The Authors.
