Insight in obsessive-compulsive disorder: a comparative study of insight measures in an Israeli clinical sample

Attempts to identify the characteristics of OCD patients with poor insight have not produced a coherent picture. This may be related to the wide variety of the available insight assessment tools. The study aimed to compare five principal measure for assessing insight in OCD and to investigate the relationships between insight and central demographic and clinical variables.

Sixty outpatients diagnosed with OCD (36 men, 24 women) were assessed with the following insight measures: DSM-IV insight criterion, Over-Valued Ideas Scale (OVIS), Item 11 of the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Brown Assessment of Beliefs Scale (BABS) and Beck Cognitive Insight Scale (BCIS).

Correlation coefficients indicated high correspondence between all insight measures with the exception of the BCIS. At the same time, the relations of the various insight measures with demographic and clinical variables were distinctive and in some cases measure-specific. The most robust correlation was between insight and current medical treatment, so that medicated participants showed higher insight levels on most insight measures compared to non-medicated participants. Some insight measures were correlated with co-morbidity, onset age and gender. Insight levels did not correlate with OCD symptom severity.

Limitations of this study include its cross-sectional design, modest sample size and an incomplete representation of the available insight measures.

The diversity of measures used in previous studies cannot account for the inconsistent findings on the role of insight in OCD.
