Objective: Information from parents is regularly used in the diagnostic process of children and adolescents with psychiatric symptoms. But the reliability of this information is debatable, because the parents’ own stress can distort their perceptions of the child’s symptoms.
Method: For each of N = 68 children and adolescents (11–18 years) who were using mental health services for the first time, we evaluated the ratings of a parent and a professional clinician (internalizing, externalizing symptoms, total-problem score). In addition, parenting stress was scored on the Eltern-Belastungs-Inventars (EBI, Tröster, 2011), which measures both child-related stress and parent-related stress as well as total stress.
Results: Highly stressed parent ratings differed more from the clinicians’ ratings than the ratings of less stressed parents. Additionally, correlations showed that higher parenting stress resulted in larger differences between the parent’s and the clinician’s assessments. Multiple regressions proved the predictive value of child-caused parenting stress for these differences. These results apply for internalizing symptoms, externalizing symptoms, and total-problem score.
Conclusions: Parenting stress should be evaluated systematically in order to carefully assess the value of the information from parents and to determine how it should be included in diagnostic and therapeutical decisions.
