The aim of the study was to evaluate the effectiveness of a media literacy intervention targeting, for the first time, the specific topic of Performance and Appearance Enhancing Substances (PAESs) use in high-school students. Overall, 389 students (52% male) aged between 13 and 19 years (mean = 16.56 year; SD = 1.26) participated to a media literacy intervention (i.e., “intervention group”) while 103 students aged between 14 and 19 year (mean = 16.10 year; SD = 1.38) were considered as the control group (i.e., “control group”). In two separate occasions over the course of six consecutive months, students in both groups filled out a set of questionnaires which included measures of social-cognitive beliefs (i.e., attitudes, subjective norms, intentions) and a self-reported measure of retrospective use of doping (Yes/No) and supplements (Yes/No). Compared to students in the control group (Mean(time1) = 1.96; SD(time1) = 0.85; and Mean(time2) = 2.09; SD(time2) = 0.94), intervention students on average expressed relatively stronger attitudes against doping use over time (Mean(time1) = 2.2; SD(time1) = 0.85; and Mean(time2) = 2.05; SD(time2) = 0.82). Students in the latter group also showed a statistically significant decrease in self-reported supplement use (Use(time1) = 6.7%; Use(time2) = 3.8%; p = 0.05, McNemar Test). Interestingly, albeit marginally significant, students in the control group showed a relative increment in the self-reported use of supplements over time (Use(time1) = 4.9%; Use(time2) = 8.7%; p = 0.22, McNemar Test). Overall, the media literacy intervention investigated in the present study was effective in decreasing adolescent student’s positive attitudes toward doping use and in reducing the use of legal PAES. These findings supported the generalizability and the usefulness of a media literacy approach in the specific field of PAES.

Relationships between sociocultural factors (gender, immigrant and socioeconomic background), peer relatedness and positive afect in adolescents

In the study, based on a representative sample of 26,670 Italian fifth-grade students, the authors examine the academic motivational profiles of immigrant and native students, as well as of boys and girls. To reliably estimate mean differences, the measurement invariance of a short version of the Academic Self-Regulation Questionnaire was first established across the groups. Boys reported less autonomous motives for studying than girls while first-generation immigrant pupils showed higher levels of intrinsic motivation, identified regulation, and external regulation for studying than natives did. Also, second-generation immigrants had higher levels of academic motivation than natives did, although they were less motivated and reported less autonomous reasons for studying than first generations. While confirming the immigrant paradox in a country with a rapidly increasing level of immigrant students, findings show that second-generation immigrants not only report a lower quantity of motivation than first-generations, but also appear to have a different quality of motivation

Objective Physical distancing behavior (PDB) is a key disease prevention strategy for limiting the spread of COVID-19. In order to effectively encourage it among adolescents, it is necessary to understand the associated mental mechanisms. Health behavior theories suggest that emotions, personality, motivation, and moral disengagement could all play a role. On the basis of a longitudinal study, we investigated the importance of these factors in predicting PDB. Methods The participants were 347 adolescents residing in Italy. Data were collected in four waves starting from 1 year before the pandemic. A structural equation model based on health behavior theory was tested. Results After the COVID-19 national lockdown, adolescents experienced fewer positive emotions and more negative emotions compared with 1 year earlier. Nevertheless, these emotional changes, and adolescents’ personality (except for openness to experiences), were not related to the adoption of PDB. Instead, the autonomous motivation of adolescents significantly predicted a higher likelihood to adopt PDB by increasing the intention to engage in this behavior and, more indirectly, by substantially decreasing moral disengagement, which was negatively related to PDB. In contrast, controlled motivation corresponded to significantly higher levels of moral disengagement and predicted less likelihood of adopting PDB. Conclusions Messages and interventions targeted at adolescents should be oriented towards supporting autonomy, emphasizing the personal and social value of PDB. Communications should avoid the use of coercive strategies based on eliciting emotions such as shame and guilt in adolescents who do not adopt PDB, which appear to trigger off mechanisms of moral disengagement.

A prospective field study conducted with runners training for an upcoming marathon (Marathon of Rome 2013) examined the relation between regulatory modes, locomotion and assessment, and stress. Integrating regulatory mode theory and the dualistic model of passion, we hypothesized that the relation between regulatory modes (evaluated 3 months before the race) and the experience of stress approaching the marathon, is mediated by the type of passion (harmonious vs obsessive) athletes experience with regard to marathoning. Results revealed that (a) locomotion positively predicted harmonious passion, which in turn reduced athletes' experience of stress; and (b) assessment positively predicted obsessive passion, which in turn enhanced athletes' experience of stress. Overall, the present results suggest that proximal psychological mechanisms such as basic regulatory mode orientations can predict distal outcomes such as stress indirectly through their relation with motivational phenomena such as passion.
