Involvement in bullying and depression in a 2-year follow-up in middle adolescence

The main objective was to analyse whether involvement in bullying at school predicts depression, and whether depression predicts involvement in bullying in middle adolescence. A total of 2,070 15-year-old girls and boys in two Finnish cities were surveyed at ninth grade (age 15) at schools, and followed up 2 years later in the Adolescent Mental Health Cohort Study (AMHC). Depression was measured by a Finnish modification of the 13-item short Beck Depression Inventory. Involvement in bullying was elicited by three questions focusing on being a bully, being a victim to bullying, and being left alone by peers against one's wishes. Similar questions were posed at both time points. Statistical analyses were carried out using cross-tabulations with chi-square/ Fisher's Exact Test statistics, and logistic regression. The results summarized that, both being a victim to bullying and being a bully predicted later depression among boys. Among girls, depression at T1 predicted victimisation at T2. Depression at T1 predicted experience of being left alone at T2 among both sexes. It was concluded that victimisation to bullying may be a traumatising event that results in depression. However, depression also predicts experience of victimisation and of being left alone against one’s wishes. Depression may impair an adolescent’s social skills and self-esteem so that the adolescent becomes victimised by peers. However, depression may also distort and adolescent’s experiences of social interactions

Changes over time in mental health symptoms among adolescents in Tampere, Finland

Background: Mental health problems are common in adolescence and seeking help for them is becoming more common. Referrals to adolescent mental healthcare have recently increased in Finland. Objective: To examine time trends in internalizing and externalizing mental health symptoms among Finnish adolescents. Method: A time-trend school survey was conducted among 9th graders (15-year-olds) in Tampere, Finland, in three time periods: 2002-03, 2012-13 and 2018-19 (N = 4,162). Results: Compared to the period 2002-03, prevalence of externalizing symptoms decreased in the period 2012-13 and further in 2018-19. The prevalence of internalizing symptoms did not change significantly between 2002-03 and 2012-13; however, in 2018-19, depression, social anxiety, general anxiety, poor subjective health, stress symptoms among boys, and poor selfesteem increased compared to earlier time periods. The increases were more marked among girls. However, suicidal ideation did not increase in 2018-19 compared to earlier time periods. Conclusion: Whereas the prevalence of externalizing symptoms decreased among Finnish adolescents between 2002-03 and 2018-19, the prevalence of internalizing symptoms increased between 2012-13 and 2018-19. To help to understand the causes of these increases and to prevent internalizing problems, further research on the underlying causes is needed.Peer reviewe

Experiences of sexual harassment are associated with the sexual behavior of 14-to 18-year-old adolescents

Subjection to sexual harassment is associated with a number of negative outcomes, such as internalizing and externalizing symptoms and a disinclination to attend school. Among adolescents, sexual harassment may increase with both their emerging sexual desires and increased socializing in mixed-gender peer groups during early adolescence. We set out to study the possible associations between normative and risk-taking sexual behavior and subjection to sexual harassment among adolescents between the ages of 14 and 18 years. The informants included 90,953 boys and 91,746 girls, with a mean (SD) age of 16.3 (1.2) years, who responded to a classroom survey (School Health Promotion Study 2010-2011) in Finland. We found that even early steps in romantic and erotic experiences were associated with experiences of sexual harassment. The more advanced the adolescents' sexual experiences were, the more commonly they reported differing experiences of sexual harassment. These associations were particularly strong among the girls. Among the sexually active adolescents, the more partners the adolescents had for intercourse, the more commonly they reported experiences of sexual harassment. Adolescents actively interested in romantic and sexual relationships may socialize in contexts where sexual harassment is more likely to occur. They may be more sensitive to sexual cues than their non-interested peers, or sexual harassment may be a traumatic experience predisposing adolescents to risk-taking sexual behavior as a form of acting out. A double standard regarding the appropriate expression of sexuality received some support in our data.Peer reviewe

Family Characteristics, Transgender Identity and Emotional Symptoms in Adolescence: A Population Survey Study

Sociodemographic and psychosocial family factors have profound implications for adolescent development, identity formation and mental health during the adolescent years. We explored the associations of sociodemographic and psychosocial family factors with transgender identity in adolescence and the role of these factors in the associations between gender identity and emotional disorders. Data from a large adolescent population survey from Finland were analysed using logistic regression models. Reporting transgender identity was associated with mother’s low level of education, accumulating family life events, lack of family cohesion, perceived lack of family economic resources and female sex. A lack of family cohesion further differentiated between adolescents reporting identifying with the opposite sex and those reporting non-binary/other gender identification. The associations between transgender identity, depression and anxiety were attenuated but did not level out when family factors were controlled for. Transgender identity in adolescence is associated with socioeconomic and psychosocial family factors that are known correlates of negative outcomes in mental health and psychosocial well-being. However, transgender identification is also associated with emotional disorders independent of these family factors

Mediators between adverse childhood experiences and suicidality

We investigated whether psychiatric symptomatology, impulsivity, family and social dysfunction, and alcohol use mediate the relationship between adverse childhood experiences (ACEs) and suicidality. The study population comprised 206 adolescent psychiatric inpatients and 203 age- and gender-matched adolescents from the community. ACEs and suicidality were assessed using the Schedule for Affective Disorders and Schizophrenia for School-Age Children Present and Lifetime version, the Life Events Checklist, and a structured background data collection sheet. Psychiatric symptomatology was measured using the Symptom Checklist -90. Impulsivity, social dysfunction, and family dysfunction were measured using the Offer Self-Image Questionnaire, and alcohol use was assessed with the Alcohol Use Disorders Identification Test. A simple mediation test and multiple mediation analyses were conducted. A positive direct effect of ACEs on suicidality was observed. Also seen was a positive indirect effect of ACEs on suicidality through psychiatric symptomatology, impulsivity, and family and social dysfunctions. Alcohol misuse did not, however, mediate the relationship between ACEs and suicidality. According to the multiple mediation analyses, psychiatric symptomatology was the most significant mediator, followed by impulsivity. Psychiatric symptoms, impulsivity, and family and social dysfunctions are factors that should be taken into consideration when assessing suicidality in adolescents.Peer reviewe
