Paediatric headache trajectories - a reappraisal after nine years.

Background The long-term consequences of paediatric headache can involve functional disabilities and mental health problems in adulthood. Objective To analyse the predictive power of paediatric headache trajectory classes for headache and related outcomes in adulthood. Methods In a previous study, a population-based sample (N = 3227, 9-14 years of age at first assessment) was followed across four annual assessment points, and sex-specific headache trajectory classes were identified (girls: "no pain", "moderate pain", "increasing pain", "high pain"; boys: "no pain", "moderate pain").

Developmental trajectories of paediatric headache - sex-specific analyses and predictors.

Background: Headache is the most common pain disorder in children and adolescents and is associated with diverse dysfunctions and psychological symptoms. Several studies evidenced sex-specific differences in headache frequency. Until now no study exists that examined sex-specific patterns of change in paediatric headache across time and included pain-related somatic and (socio-)psychological predictors.

Two dimensions of social anxiety disorder: a pilot study of the Questionnaire for Social Anxiety and Social Competence Deficits for Adolescents.

Background: The Questionnaire for Social Anxiety and Social Competence Deficits for Adolescents (SASKO-J) was developed as an instrument for clinical diagnostics of social anxiety disorder in youths by measuring social anxiety and social deficits in two separate dimensions. The study provides an initial assessment of the scale's psychometric properties in a clinical sample.

Method: The reliability and validity of the SASKO-J were assessed in a mixed clinical sample of 12- to 19-year-old German adolescents (N = 85; mean age 15.

Developmental trajectories and predictors of externalizing behavior: a comparison of girls and boys.

Recent studies have shown that the development of externalizing behavior in childhood and adolescence can be described through different developmental pathways. However, knowledge about differences between the sexes regarding the trajectories is limited. This study focused on potential differences by examining the trajectories of self-reported externalizing symptoms for girls and boys separately.

Different trajectories of depressive symptoms in children and adolescents: predictors and differences in girls and boys.

The development of depressive symptoms in childhood and adolescence can follow different pathways. This study examined heterogeneity in the development of self-reported depressive symptoms and the predictive influence of mothers' depressive symptoms, the number of life events, and loss events via growth mixture modeling over a four-year period in a large community sample of German children and adolescents (N = 3,902; mean age 11.39 years; 49.
