[The parent questionnaire "ADHD-knowledge and motivation for treatment" - development and first results]

Psychoeducation of parents and caregivers is an important component of treatment for ADHD. So far, standardized instruments to indicate an evaluate psychoeducation are scarce. This study describes the development of a parent questionnaire to assess ADHD-specific knowledge and motivation for treatment.

Items were generated based on scientific evidence, comprising knowledge about symptoms, etiology and treatment for ADHD, as well as willingness to adhere to concrete treatments. The questionnaire was developed based on theoretical assumptions and on principles of classical test construction. The psychometric analysis of the final version was performed in a sample of 105 parents of children with suspected diagnosis ADHD.

The questionnaire comprises 37 Items on three scales basis knowledge, differentiated knowledge, and motivation for psychosocial treatment. Motivation for medical treatment is assessed separately.

Preliminary psychometric analyses support the multi-dimensional representation of ADHD-specific knowledge and motivation for treatment. Further analyses of the validity of the questionnaire and on the sensitivity for changes should be undertaken.
