Executive Functions, Psychiatric Symptoms and ADHD in Child Psychiatric Patients-Concurrent and Longitudinal Associations from Preschool to School Age.

We investigated in a child psychiatric sample whether preschool age executive functions (EFs) associate with concurrent and school age psychiatric symptoms and ADHD diagnosis. At baseline the children (n = 172) were 4-7 years old, at follow-up (n = 65) 8-13 years. EFs were measured at baseline with Attention and Executive Function Rating Inventory-Preschool Version, psychiatric symptoms were measured at both timepoints by Child Behavior Checklist.

Sleep and psychiatric symptoms in young child psychiatric outpatients - a Follow-up study.

Background: Knowledge of the continuity of sleep problems and the associations between sleep and psychiatric symptoms in child psychiatric patients is scarce.

Objectives: To investigate the persistency of sleep problems and how sleep at preschool age predicts sleep problems and psychiatric symptoms at school age in child psychiatric patients.

Methods: Participants ( = 68) were child psychiatry outpatients at Helsinki University Hospital in 2015-2017.

Longitudinal associations between inhibitory control and externalizing and internalizing symptoms in school-aged children.

Inhibitory control (IC) deficits have been associated with psychiatric symptoms in all ages. However, longitudinal studies testing the direction of the associations in childhood are scarce. We used a sample of 2,874 children (7 to 9 years old) to test the following three hypotheses: (a) IC deficits are an underlying risk factor with a potentially causal role for psychopathology, (b) IC deficits are a complication of psychopathology, and (c) IC deficits and psychopathology are associated at the trait level but not necessarily causally related.

Low mood in a sample of 5-12 year-old child psychiatric patients: a cross-sectional study.

Background: Not much is known about low mood and its associates in child psychiatric patients. In this study, we examined the prevalence of low mood, how it associates with disruptive behaviour, and affects clinician-rated global functioning in child psychiatric outpatients.

Methods: The study population consisted of 862 5-12 year-old child psychiatric patients.
