Alcohol Use and Abstinence throughout Adolescence: The Changing Contributions of Perceived Risk of Drinking, Opportunities to Drink, and Self-Control

Objective: Adolescence is characterized by psychosocial and cognitive changes that can alter the perceived risk of negative effects of alcohol, opportunities to drink, and self-control. Few studies have investigated whether these factors change in their contribution to adolescent drinking over time. This study examined associations between perceived risk, opportunities to drink, self-control, and past-year drinking and investigated whether self-control buffers the effect of lower perceived risk and frequent drinking opportunities on the probability of past-year drinking. Method: Data from a four-wave longitudinal study (2015-2020) of 2,104 North Carolina adolescents (Mage = 12.36, SDage = 1.12, at Time 1) were used to assess changes in associations between self-control, perceived risk of drinking, and drinking opportunities on the frequency of past-year drinking. Hypotheses were tested using latent trajectory models. Results: At all timepoints, greater perceived risk, fewer drinking opportunities, and higher self-control were associated with drinking abstinence in the past year. Self-control buffered the impact of frequent drinking opportunities and lower perceived risk on the probability of alcohol use at Times 1-3. Conclusions: Despite expectations that adolescents' ability to navigate their environments improves as they age, associations between risk, protective factors, and past-year drinking were relatively stable over time. Nevertheless, self-control protected against frequent drinking opportunities and lower perceived risk. Strategies that support or relieve the need for self-control (e.g., situation modification) may protect against alcohol use throughout adolescence.

The triple psychological and neural bases underlying procrastination: Evidence based on a two-year longitudinal study

The triple brain anatomical network model of procrastination theorized procrastination as the result of psychological and neural dysfunction implicated in self-control, emotion regulation and episodic prospection. However, no studies have provided empirical evidence for such model. To address this issue, we designed a two-wave longitudinal study where participants underwent the resting-state scanning and completed the questionnaires at two time-points that spanned 2-year apart (T1, n = 457; T2, n = 457). Using the cross-lagged panel network modeling (CLPN), we found that triple psychological components at T1, including self-control, emotion regulation (i.e., reappraisal) and episodic prospection, negatively predicted procrastination at T2 in the temporal network. Moreover, the CLPN modeling found that functional connectivity between networks accounting for episodic prospection (EP) and emotion regulation (ER) positively predicted future procrastination in the temporal network. The centrality analyzes further showed that procrastination was greatly affected by other nodes, whilst the psychological component (i.e., episodic prospection), and the functional network connectivity (FNC) of EP- ER exerted strongest impacts on other nodes in the networks, which indicated that treatments targeting episodic prospection might largely help reduce procrastination. Collectively, these findings firstly provide evidence for testifying the triple brain anatomical network model of procrastination, and highlights the contribution of triple psychological and neural components implicated in self-control, emotion regulation and episodic prospection to procrastination that enhances our understanding of causes of procrastination.

Influence of family cohesion on Chinese adolescents' engagement in school bullying: A moderated mediation model

In this study, a total number of 1,026 Chinese adolescents were surveyed using the cohesion sub-scale of the Family Environment Scale, the Self-control Scale, the Parental Monitoring Questionnaire, and the revised Olweus Bully/Victim Questionnaire to explore the effects of family cohesion on adolescents' engagement in school bullying and the mechanisms of self-control and parental monitoring in the relationship between them. The results showed that: (1) family cohesion, self-control, and parental monitoring were significantly and negatively related to school bullying; (2) family cohesion directly influenced school bullying and also indirectly influenced school bullying through a mediating effect - self-control; (3) parental monitoring played a moderating role in the path of self-control affecting school bullying. Therefore, to reduce the occurrence of school bullying, it is necessary to strengthen the self-control ability of adolescents and improve the family cohesion environment and maintain a moderate level of parental monitoring. The results of this study revealed the effect of family cohesion on adolescents' engagement in school bullying and its mechanism of action, which can provide a theoretical basis for preventing and reducing the occurrence of school bullying incidents.
