A longitudinal study of protective factors against substance use in early adolescence. An ecological approach.

BACKGROUND: Adolescent substance use has been widely related to different individual, school, family and community factors. Yet, the number of studies with all these variables together in a model from an ecological perspective is still low, and they rarely used a longitudinal design. The aim of this study was to explore, from an ecological perspective, the prospective impact of different individual, school, family and neighbourhood factors on adolescent substance use. METHODS: This was a longitudinal study with a one-year follow up. There were 881 participants (Mage = 12.57; 48.1% females) at wave 1, of which 686 (Mage = 13.51; 51.8% females) were followed-up at wave 2. Validated questionnaires were used for data collection. RESULTS: Regression analyses showed that higher substance use was predicted by high family socio-economic status cross-sectionally and longitudinally, and it was related to low neighbourhood socio-economic status cross-sectionally only. Participants who disliked school and had a poor academic performance were more likely to use substances, both cross-sectionally and longitudinally. CONCLUSIONS: The inclusion of families in substance use prevention programmes could be a key component in these interventions. Moreover, promotion of a positive school climate could protect adolescents from using substances.

Empathy, social and emotional competencies, bullying perpetration and victimization as longitudinal predictors of somatic symptoms in adolescence.

BACKGROUND: Somatic symptoms are an important adolescent health problem that affects individuals and the society as a whole. Although research focused on somatic symptoms has been very fruitful, studies about their longitudinal predictors are still in their early stages. The present study focuses on the relations between social and emotional competencies, empathy and bullying, and the presence of somatic symptoms concurrently and one year later. METHOD: The sample consisted of 384 Spanish adolescents, who participated in a longitudinal study with a one-year follow-up. Validated questionnaires were used to assess social and emotional competencies, bullying, empathy and somatic complaints. RESULTS: High scores in social and emotional competencies were related to low scores in somatic symptoms one year later. High affective empathy predicted more somatic symptoms concurrently and one year later. Bullying victimization was related to more somatic symptoms concurrently and one year later. LIMITATIONS: Other-reports could be useful to further validate the results obtained with self-reports. Non-linear relations could be tested. Representative samples could be used in future studies. CONCLUSIONS: These results suggest that it may be important to promote social and emotional competencies and reduce bullying to decrease somatic symptoms. More studies are needed to understand the impact of high affective empathy on somatic symptoms.
