The aim of the current study was to compare mental health problems, resilience and family characteristics in adolescents with and without delayed @entity25 (DSP) in a population-based sample. Data were taken from the youth@hordaland-survey, a large population-based study in Hordaland County in Norway conducted in 2012. In all, 9338 adolescents aged 16-19  years (53.5% @entity1 ) provided self-reported data on a wide range of instruments assessing mental health symptoms, including @entity308 , @entity148 , @entity3119 , @entity71 ( @entity71 ) symptoms, perfectionism, resilience and sleep. Measures of socioeconomic status were also included. Three hundred and six adolescents (prevalence 3.3%) were classified as having DSP [according to the International Classification of Sleep Disorders-2 (ICSD-2)] criteria. Adolescents with DSP reported higher levels of @entity308 , @entity148 and @entity71 symptoms. Adolescents with DSP also exhibited significantly lower levels of resilience. The Cohen's d effect sizes ranged from small [ @entity3119 ( @entity3119 ): d  =  0.15] to moderate (inattention: d  =  0.71). In the fully adjusted model, the significant predictors of DSP included inattention [odds ratio (OR): 2.11], lack of personal structure (OR: 2.07), low (OR: 1.85) and high (OR: 1.91) paternal education, parents not living together (OR: 1.81), @entity2915 /inattention (OR: 1.71) and poorer family economy (OR: 1.59). In conclusion, the high symptom load across a range of mental health measures suggests that a broad and thorough clinical approach is warranted when adolescents present with DSP.
