Trajectories of participation, mental health, and mental health problems in adolescents with self-reported neurodevelopmental disorders.

Gender is an important factor with girls exhibiting more problems. Mental health explains more of the variation in participation than mental health problems and NDD. Probably participation intervention can enhance mental health which may protect from mental health problems.Implications for rehabilitationMental health, i.e., emotional-, social-, and psychological well-being is more strongly related to participation and to reduced levels of mental health problems than having an NDD or not, thus assessing mental health separately from measuring NDD is important.Interventions focusing on participation may lead to higher mental health and having high mental health (flourishing) may facilitate participation.Girls with self-reported NDD seem to have a higher burden of mental health problems, especially if they also are languishing, i.e., having low mental health, therefore a strong focus on this group is needed both in research and clinical practice.Half of all adolescents are flourishing, independently of NDD or not, even if they are experiencing some symptoms of mental health problems, adolescents with NDD who are also languishing, have much higher ratings of mental health problems.
