Psychometric properties of the Dutch version of the Meta-Cognitions Questionnaire-Adolescent Version (MCQ-A) in non-clinical adolescents and adolescents with obsessive-compulsive disorder.

Although the meta-cognitive model (Wells, 1997, 2000) for obsessive-compulsive disorder (OCD) has clearly influenced research and treatment of OCD, little research has been performed in youth samples. In the present study the psychometric properties of the Dutch Meta-Cognitions Questionnaire-Adolescent Version (MCQ-A; Cartwright-Hatton et al., 2004) were examined in a clinical sample of adolescents with OCD (N = 40, 12-18 years) and a non-clinical sample (N = 317; 12-18 years). Results provided support for the 5-factor structure, and showed fair to good internal consistency and generally good retest reliability. Overall, adolescents with OCD reported more meta-cognitive beliefs than non-clinical adolescents. Several subscales were associated with self-reported obsessive-compulsive symptoms, anxiety and depression, but not with clinician-rated OCD severity. In conclusion, results suggest that the Dutch MCQ-A is a reliable and valid questionnaire to examine meta-cognitive beliefs in adolescents.

Psychometric properties of a Dutch version of the Obsessive Beliefs Questionnaire--Child Version (OBQ-CV).

To improve research in cognitive theories of childhood OCD, a child version of the Obsessive Beliefs Questionnaire (OBQ-CV) has been developed (Coles et al., 2010). In the present study, psychometric properties of the Dutch OBQ-CV were examined in a community sample (N=547; 8-18 years) and an OCD sample (N=67; 8-18 years). Results revealed good internal consistency and adequate retest reliability (retest interval 7-21 weeks and 6-12 weeks, respectively). Children with OCD reported more beliefs than non-clinical children. Obsessive beliefs were related to self-reported OCD symptoms, but not to clinician-rated OCD severity. Beliefs were also related to anxiety and depression. This is the first study examining the factor structure of the OBQ-CV. Confirmatory factor analyses revealed best fit for four factors representing Perfectionism/Certainty, Importance/Control of Thoughts, Responsibility, and Threat, and a higher-order factor. This is in line with results from adult samples. These results support the reliability and validity of the Dutch OBQ-CV.

The psychopathology of parents of children and adolescents with obsessive-compulsive disorder.

Our purpose was to determine the rates of psychopathology in parents of children and adolescents with obsessive-compulsive disorder (OCD) and compare these with that found in parents of children with learning disorders of reading and written expression. Thirty-one children with OCD, aged 8-15 years, and their parents (n = 62), aged 43-48 years, were studied and compared to 30 children with learning disorders, aged 7-16 years, and their parents (n = 58), aged 40-46 years. In order to investigate the parental psychopathology, the Symptom Checklist-90-R (SCL-90-R), the State and Trait Anxiety Inventory and the Yale-Brown Obsessive-Compulsive Scale were administered. The psychopathology of children was examined through the Schedule for Affective Disorders and Schizophrenia for school-aged children and other instruments. Both fathers and mothers of the probands differed from the controls in a variety of symptoms (i.e. anxiety, depression, obsessions, etc.). Both parents had increased severity of OC symptomatology in comparison to the controls. In addition, the probands' fathers had severe OC symptomatology at a higher percentage than the mothers and respective controls. The elevated scores of the parents of children with OCD in some SCL-90-R subscales can be perceived as an index of heightened psychopathology. More fathers in the OCD group, compared to mothers and controls, were found to have OC symptoms in the SCL-90-R and increased severity of OC symptoms on the Yale-Brown Obsessive-Compulsive Scale. The last finding requires further study. Parental psychopathology in children with OCD needs to be addressed clinically.
