Peer victimization can lead to dysfunctional cognitions and numerous internalizing psychological problems. Thus, it is essential to identify factors that can moderate the impact of victimization. This study aimed to analyze the potential moderating role of perceived executive functions (PEF) in the impact of peer victimization (traditional and online) on internalizing symptoms (depression and social anxiety), early maladaptive schemas (disconnection/rejection domain), and PEF in adolescents. A two-wave longitudinal study was carried out with 680 Spanish adolescents between 12 and 17 years of age (M = 14.58, SD = 1.36; 41.18% girls). Participants completed measures of self-reported executive functions, traditional and online victimization, early maladaptive schemas of the disconnection/rejection domain, depressive symptoms, and social anxiety symptoms in waves 1 and 2. Traditional and online perpetration was completed only in wave 1. The results indicated that when PEF were high (i.e., adolescents perceive that they have good executive functions), traditional and online victimization predicted more schemas of the disconnection/rejection domain and internalizing symptoms of depression and social anxiety. In non-victims, high PEF showed a protective role in the development of depressive symptoms and schemas of the disconnection/rejection domain. The findings highlight that PEF have a protective role that disappears when victimization (traditional and online) occurs.

The consequences of cyberbullying victimization can lead to its perpetuation over time, initiating a vicious cycle. Thus, it is important to identify the factors that contribute to the persistence of victimization. This study aimed to examine some longitudinal mechanisms involved in the perpetuation of cyberbullying victimization in adolescents. The secondary aim was to study the protective role of executive functions (cognitive flexibility and selective attention) in this process, filling a gap in the literature. Sex differences were also studied. The sample consisted of 698 adolescents between 12 and 17 years of age (M = 14.59, SD = 1.36; 40.83% girls) from the Basque Country (Spain). Adolescents participated in a longitudinal study with three waves, in which 5–6 months elapsed between waves. The participants completed measures of executive functions in wave 1, of cyberbullying perpetration and depressive symptoms in waves 1 and 2, and of cyberbullying victimization in all three waves. The findings indicated that cyberbullying victimization was perpetuated through an increase of cyberbullying perpetration and depressive symptoms. Concerning executive functions, cognitive flexibility attenuated the impact of cyberbullying victimization on cyberbullying perpetration and depressive symptoms, and these in turn predicted lower levels of future victimization. Sex differences revealed that selective attention acted as a risk factor for cyberbullying victimization in girls and as a protective factor in boys. The results highlight the importance of considering mediating mechanisms involved in the perpetuation of cyberbullying victimization as well as the beneficial role played by cognitive flexibility in reducing the stability of cyberbullying victimization.

This randomized controlled trial (NCT04786496) examined the effects of a preventive intervention based on Incremental Theory of the Personality (ITP) on psychophysiological responses to social stress and evaluated whether levels of depression moderate the intervention effects. The participants, 107 first-year university students, were randomly assigned to one of three conditions: ITP intervention, ITP + a self-affirmation intervention (SA), and a control condition (CC). Indicators of the Hypothalamic–Pituitary–Adrenal axis, autonomic nervous system, and subjective mood were assessed with the Trier Social Stress Task. Participants in the ITP condition displayed a lower decline in respiratory sinus arrythmia (RSA) compared to those in the CC during the first phases of the task [Slopes: -0.08 (0.09) vs -0.21 (0.09), z = 2.86, p = .004] and a higher decrease in cortisol at recovery [β = -0.18 (0.08), z = -2.37, p = .018]. Depressive symptoms moderated the effect of ITP [β = -0.10 (0.05), z = -2.15, p =.032] and ITP+SA [β = -0.09 (0.04), z = -2.06, p =.039] in the decline during stress and recovery in RSA. In participants with low/medium levels of depressive symptoms, both interventions predicted a lower decline during stress [Slopes: -0.06 (0.09) for ITP, -0.17 (.09) for ITP+SA, and -0.26 (0.09) for CC] and higher recovery in RSA [Slopes: 0.18 (0.01) for ITP, 0.24 (0.01) for ITP+SA, and 0.30 (0.01) for CC]. The findings suggest that the ITP intervention has the potential to be an effective preventive intervention to reduce the stress response.

Online sexual solicitation involves receiving sexual solicitations from adults, which can be followed by active online sexual behaviors by the victims. This study examined the moderator role of some characteristics of adolescents (sex, age, and problematic Internet use) that could make them more vulnerable to react by engaging in active sexual behaviors when they are the recipients of sexual solicitations. The final sample was comprised of 1260 adolescents (55.6% girls, 12–17 years) who completed measures in two waves with an interval of one year. The measures included online sexual solicitation, active sexual interaction with an adult, and sexting to friends and/or one's partner in both waves of the study. Sexual solicitations by adults predicted an increase in sexualized interactions with adults and sending sexts to friends and/or one's partner. Moderation tests indicated that, although girls receive more sexual solicitations, they are actively involved to a lesser extent than boys in sexualized interactions with adults and in sending sexts. The youngest adolescents received fewer sexual solicitations, but those who did receive sexual solicitations sent more sexts to friends and/or one's partner. Problematic Internet use, although associated with all online sexual risks, did not moderate the dynamics between risks.

Although both executive functions and internalizing symptoms go through important changes during adolescence, the role of executive functions in internalizing symptoms is unclear. Based on developmental cascade models of psychopathology, this study aimed to fill this gap by studying the bidirectional predictive relationship between executive functions (cognitive flexibility and selective attention) and symptoms of depression and social anxiety. A sample of 698 adolescents (40.8% girls) between 12 and 17 years of age (M = 14.59, SD = 1.36) participated in three waves over 1 year. They completed measures of executive functions and internalizing symptoms. Depressive symptoms predicted deficits in executive functions. Conversely, social anxiety symptoms predicted an improvement in cognitive flexibility. These results suggest that executive function deficits are not a risk factor for the development of depressive symptoms but a consequence of them, and there are specific patterns of associations for depressive and social anxiety symptoms.

This study, based on a transactional perspective of psychopathology, aimed to examine whether the mindful attention and awareness component of mindfulness moderates the bidirectional long-term predictive associations between dependent stressors, maladaptive schemas, and depressive symptoms in adolescents. It was hypothesized that mindful attention and awareness would buffer the predictive bidirectional associations between these variables. The sample was composed of 1190 high school students (48.7% girls) from the Basque Country (Spain), who participated in a two-wave longitudinal study spaced 2 years apart. The participants were all between 13 and 18 years old (M = 15.16, SD = 0.95). They completed a measure of dispositional mindfulness at wave 1, and measures of dependent stressors, schemas from the disconnection/rejection schema domain, and depressive symptoms at both waves. Results indicated that mindful attention and awareness reduced the predictive associations between disconnection/rejection schemas and depressive symptoms at follow-up (wave 2). In addition, mindfulness predicted lower scores on maladaptive schemas, dependent stressors, and depressive symptoms at follow-up and buffered the stability of schemas over time. However, these findings were statistically significant only for boys. The results suggest that mindfulness-based intervention can be used to reduce maladaptive schemas that are relevant for depressive symptoms in adolescents.
