Transactional processes between childhood maltreatment and depressive symptoms from middle childhood to early adolescence: Locus of control as a mediator

A serial cascade effect of cybervictimization and hostile rumination on the within-person change of moral disengagement

OBJECTIVE

There is a lack of clarity regarding the developmental mechanisms underlying moral disengagement (a typical moral personality) at the within-person level. To address this issue, we explore the serial cascade effect of cybervictimization and hostile rumination.

METHOD

The longitudinal relationships between cybervictimization, hostile rumination, and moral disengagement were explored among 1146 undergraduates, assessed four times (T1-T4) across 2 years.

RESULTS

The random intercept cross-lagged panel model (RI-CLPM) analysis revealed that the random intercepts of all variables were positively associated with each other. At the within-person level, cybervictimization at T2 indirectly predicted subsequent changes in moral disengagement at T4 through changes in hostile rumination at T3 (the indirect effect was 0.02); furthermore, moral disengagement at T3 predicted changes in hostile rumination at T4 (β = 0.091).

CONCLUSIONS

The within-person dynamics of moral disengagement should be partly due to the serial effect of cybervictimization and hostile rumination, whereas hostile rumination and moral disengagement may form a developmental cascade to some degree. These findings and the proposed serial cascade model of moral disengagement could expand our understanding of the developmental mechanism of moral personality. Additionally, caution must be exercised as this study exhibits seemingly small effect sizes and inconsistent results.

Examining bidirectional relations between sleep problems and non-suicidal self-injury/suicidal behavior in adolescents: emotion regulation difficulties and externalizing problems as mediators

Based on previous empirical evidences and theoretical framework, sleep problems and non-suicidal self-injury (NSSI)/suicidal behavior may bidirectionally related to one another. However, this still needs to be examined through longitudinal research. Moreover, the mediating mechanisms accounting for their potential bidirectional relations have yet to be fully investigated. This study thus aimed to evaluate whether sleep problems and NSSI/suicidal behavior promoted each other directly or indirectly through the mediating roles of emotion regulation difficulties (ERD) and externalizing problems. A total of 1648 Chinese adolescents (48.12% boys; Mage = 13.69; SD = 0.82; Age range = 11-16 years old at T1) completed self-report measures on 3-time points across 1 year. Cross-lagged panel models were used to examine the focal longitudinal associations. Results revealed a predictive effect of sleep problems on NSSI and a positive bidirectional relation between sleep problems and suicidal behavior. Moreover, sleep problems exerted an indirect effect on NSSI through ERD, and vice versa. Additionally, both ERD and externalizing problems served as mediators in the pathway from suicidal behavior to sleep problems. This study disentangled the differential mediating roles of ERD and externalizing problems in the longitudinal associations between sleep problems and NSSI/suicidal behavior, which may help provide a more holistic theoretical framework through which to precisely identify key targets for early prevention and intervention of sleep problems and NSSI/suicidal behavior in adolescents.

Longitudinal associations among smartphone addiction, loneliness, and depressive symptoms in college students: Disentangling between- And within-person associations

BACKGROUND

Smartphone addiction and depressive symptoms are two prevalent and highly correlated problems among college students worldwide. However, the causal relationships and potential mechanisms (e.g., loneliness) between them remain controversial. Thus, the present study investigated the dynamic longitudinal relations between smartphone addiction and depressive symptoms including loneliness as a possible mediator in Chinese college students.

METHODS

A total of 3,827 college students (52.8% males, 47.2% females; M_age = 18.87 years, SD = 1.48) participated in a four-wave longitudinal study across two years, and the interval between waves was 6 months except for the second and the third wave (12 months). Smartphone Addiction Scale-Short Version, University of California Los Angeles Loneliness Scale-8 and Patient Health Questionnaire-9 were used to assess participants' smartphone addiction, loneliness, and depressive symptoms, respectively. Random intercept cross-lagged panel models (RI-CLPM) were utilized to separate between- and within-person effects.

RESULTS

The results of RI-CLPM demonstrated a bidirectional association between smartphone addiction and depressive symptoms (from T₃ to T₄), and loneliness (T₃) mediated the association between smartphone addiction (T₂) and depressive symptoms (T₄) at the within-person level (indirect effect = 0.008, 95%CI = 0.002-0.019).

CONCLUSIONS

Given that loneliness served as a mediator in the relation between smartphone addiction and depressive symptoms, enhancing offline interpersonal communication may hold great promise for alleviating negative emotions and reducing the dependence on online communication.

Relational model of relative deprivation, revenge, and cyberbullying: A three-time longitudinal study

Cyberbullying is a new form of aggression and can have serious consequences. Although the influencing factors of cyberbullying have been explored in the literature, less is known of the longitudinal effects of relative deprivation on cyberbullying and the mediating mechanisms underlying the effect. In this study, we explored these problems. A total of 1143 undergraduates (62.9% women, mean age = 19.46, standard deviation [SD] = 0.95) participated in three rounds of a longitudinal survey with an interval of 6 months and completed a series of self-reported questionnaires assessing relative deprivation, revenge, and cyberbullying. The results of random intercept cross-lagged panel model showed that at between-person level, the random intercepts of relative deprivation, revenge, and cyberbullying were positively associated with each other. At within-person level, relative deprivation and revenge could predict each other over time, and revenge longitudinally predicted cyberbullying. Moreover, revenge mediated the longitudinal effect of relative deprivation on cyberbullying. The results support and develop the view of the general aggression model and deepen our understanding of the development mechanism of cyberbullying.

How do physical and emotional abuse affect depression and problematic behaviors in adolescents? The roles of emotional regulation and anger

BACKGROUND

Rates of physical and emotional abuse are high among Chinese adolescents and elicit distinct psychopathologies. However, it remains unclear whether physical and emotional abuse relate to depression and behavior problems similarly or differently. In addition, few studies have examined if they share underlying mechanisms in adolescents.

OBJECTIVE

This study used longitudinal data to examine the mechanisms underlying the effect of physical and emotional abuse on depression and problematic behaviors through emotional regulation and anger in Chinese adolescents.

PARTICIPANTS AND SETTINGS

Participants were 1689 adolescents (with age ranging from 12 to 17 years) from junior and senior high schools in Zhejiang Province, China.

METHODS

Participants completed a childhood trauma questionnaire and an emotion regulation strategies questionnaire at time 1 (T1), and they completed an anger scale, a depression scale, and a problematic behaviors questionnaire one year later (T2). Structural equation modeling was used to examine the research hypotheses.

RESULTS

Physical abuse had direct positive effects on problematic behaviors but not on depression. However, emotional abuse had direct effects on depression and problematic behaviors, and indirect effects on both psychopathologies through expressive suppression and anger.

CONCLUSIONS

Physical and emotional abuse had distinct effects and influencing mechanisms on adolescents' externalizing and internalizing problems. Compared with physical abuse, emotional abuse elicited more harms and subsequent psychopathologies.

Does childhood maltreatment increase the subsequent risk of problematic smartphone use among adolescents? A two-wave longitudinal study

There is a lack of longitudinal data on the relationship between childhood maltreatment and problematic smartphone use and its underlying mechanisms. Therefore, this study aimed to examine the relationship between childhood maltreatment and adolescent problematic smartphone use and explore the mediating effects of basic psychological needs and self-compassion in this relationship. We employed a two-wave longitudinal design among 890 Chinese adolescents (49.0% males, mean age at Time 2 = 15.96 ± 0.46 years). They completed the Childhood Trauma Questionnaire and the Smartphone Application-Based Addiction Scale at Time 1, and the Basic Need Satisfaction Scale, the Self-Compassion Scale, and the Smartphone Application-Based Addiction Scale at Time 2. The results indicated that prior maltreatment experiences positively predicted adolescents' subsequent problematic smartphone use (p < .001); and basic psychological needs satisfaction and self-compassion did not parallelly mediate the relationship between prior maltreatment experiences and subsequent problematic smartphone use. Finally, basic psychological needs satisfaction and self-compassion completely and sequentially mediated the relationship between prior maltreatment experiences and subsequent problematic smartphone use. Interventions that target students engaging in problematic smartphone use should focus on reducing childhood maltreatment and improving their psychological needs satisfaction and self-compassion.
