A recent national study from Norway has shed light on the relationship between distinct trauma types and mental health service usage among adolescents. The findings, published in the journal Child Psychiatry & Human Development, indicate a significant correlation between exposure to specific types of trauma and an increased likelihood of seeking mental health support or receiving a psychiatric diagnosis.

The study analysed data from the youth@hordaland survey, which involved 8,845 adolescents. Researchers used a Latent Class Analysis to identify three distinct trauma exposure groups among the participants: those with low trauma, situational trauma, and interpersonal trauma. The vast majority (88%) of adolescents fell into the low trauma group, while 6% were in each of the situational and interpersonal trauma groups.

Situational trauma included experiences such as accidents and multiple deaths, while interpersonal trauma comprised exposure to violence or abuse, either as a witness or victim. Notably, adolescents in both the situational and interpersonal trauma groups were significantly more likely to access child and adolescent mental health services (CAMHS) compared to their peers in the low trauma group. Furthermore, they were also more likely to be diagnosed with psychiatric conditions such as anxiety, depression, ADHD, and trauma-related disorders.

The likelihood of needing CAMHS was higher among those in the interpersonal trauma group compared to the situational trauma group, underscoring the profound impact of direct or witnessed violence on mental health. Interestingly, the study also found that adolescents exposed to interpersonal trauma had a greater prevalence of ADHD diagnoses than those in the situational trauma group, suggesting a potentially complex link between early trauma and attention-related disorders.

These findings highlight the need for mental health professionals to consider the different types of trauma exposure when assessing adolescents. Recognising these patterns can help in identifying the level of vulnerability and the possible severity of mental health issues. It also stresses the importance of screening for multiple trauma types and patterns of exposure rather than focusing on isolated traumatic events.

This large-scale registry-based study provides valuable insights into how distinct trauma patterns affect mental health outcomes and service utilisation among Norwegian adolescents. The researchers emphasised that a person-centred approach – acknowledging the heterogeneity of traumatic experiences – was crucial in understanding the complex needs of these adolescents.
