Developmental Course and Risk Factors of Physical Aggression in Late Adolescence.

This study examined risk factors of physical aggression during transition from early to late adolescence using a two-wave longitudinal study. Specifically, we examined if risk factors in early adolescence predict physically aggressive behavior starting in late adolescence and why some adolescents desist physical aggressive behavior while others do not. The study sample consisted of 2289 Norwegian adolescents (1235 girls) who participated in the Young-HUNT1 study (mean age 14.5) and the follow-up study 4 years later, Young-HUNT2 study (mean age 18.4). One in six young adolescents reported engaging in physical fights. Moreover, physical aggression in early adolescence was significantly associated with male gender, attention problems, academic problems, being bullied, drinking alcohol, and smoking. Male gender and heavy drinking during early adolescence increased the risk for newly emerging aggressive behavior in late adolescence, whereas heavy drinking during early adolescence was a predictor for persistent versus desisting aggressive behavior in late adolescence.

Resilience factors may moderate the associations between pubertal timing, body mass and emotional symptoms in adolescence.

AIM: The effects of resilience factors on associations between emotional symptoms and perceived pubertal timing or body mass in adolescence are unknown, and this study examined the moderating effects of social competence, family cohesion and loneliness. METHODS: Data were drawn from the Young-HUNT 3 study, including a self-report questionnaire and clinical measurements of weight and height from 7639 adolescents aged 13-18 years. Emotional symptoms were assessed by a five-item version of the Hopkins Symptom Checklist. Associations between pubertal timing or body mass and emotional symptoms were assessed by linear regression models. Interactions with social competence, family cohesion and loneliness were explored. RESULTS: A U-shaped relationship was found for both perceived pubertal timing and for perceived body mass and emotional symptoms. For girls, early perceived pubertal timing was more strongly associated with emotional symptoms among those who often felt lonely. For boys, late perceived pubertal timing and feeling they were fat were more strongly associated with emotional symptoms in those with low scores for social competence or family cohesion. CONCLUSION: Emotional symptoms were more strongly associated with perceived pubertal timing and body mass than actual measures and the associations were stronger for adolescents with low scores for resilience factors.

Chronic multisite pain in adolescent girls and boys with emotional and behavioral problems: the Young-HUNT study.

The aim of this study was to assess the prevalence of chronic multisite pain with high disability in relation to emotional or behavioral problems and resilience factors in adolescence. A second aim was to investigate if resilience factors could attenuate the associations between psychiatric symptoms and chronic multisite pain. The study was based on a large cross-sectional study carried out in Norway between 2006 and 2008 and included 7,070 adolescents aged 13-19 years. Chronic multisite pain was defined as pain at least once a week during the last 3 months, scoring high on a disability index, and occurring in three or more locations. Chronic multisite pain was prevalent among adolescents with high scores (>85%) for anxiety/depression, social anxiety, conduct or attention problems (22.8-31.0 for girls, 8.8-19.0% for boys). Several coexistent psychiatric symptoms increased the prevalence of chronic multisite pain for both girls and boys. Resilience factors, including high self-esteem, seldom feeling lonely, and high scores for family cohesion or social competence, were associated with a lower prevalence and markedly attenuated the association between psychiatric symptoms and chronic multisite pain. Psychiatrists should be careful to assess and treat comorbid chronic pain in adolescents with emotional or behavioral problems.

Resilience, lifestyle and symptoms of anxiety and depression in adolescence: the Young-HUNT study.

PURPOSE: This study investigated the symptoms of anxiety and depression in adolescence, their associations with lifestyle and resilience and the possibility that resilience factors can attenuate the associations between unhealthy lifestyle and symptoms of anxiety and depression. METHODS: Adolescents (n = 7,639) aged 13-18 years completed a questionnaire regarding lifestyle and health. Symptoms of anxiety and depression were measured by the SCL-5, a five-item shortened version of the Hopkins Symptom Checklist. Resilience factors included questions on friends and family relations and two sub-scales of the Resilience Scale for Adolescents; Family cohesion and Social competence. RESULTS: Of the total population, 13% reported symptoms of anxiety and depression. Resilience characteristics were associated with lower symptom levels (ORs ranging from 0.2 to 0.6), and substance use and infrequent physical activity with higher symptom levels (ORs ranging from 2.1 to 4.0). The associations with substance use were strengthened by social competence, but attenuated by family cohesion. The association with physical activity was attenuated by both social competence and family cohesion. CONCLUSION: Symptoms of anxiety and depression were frequent in adolescents and were associated with unhealthy lifestyle factors as substance use and low physical activity. Resilience characteristics seemed to protect against symptoms and markedly influenced the associations between lifestyle factors and symptoms of anxiety and depression. The importance of family and other supportive relationships should be emphasized in treatment and prevention of anxiety and depression in adolescence.
