Concordance of assessment of insight by different measures in obsessive-compulsive disorder: An outpatient-based...

This study aimed to examine the (a) prevalence of various levels of insight among patients with obsessive-compulsive disorder (OCD) and (b) correlation of insight specifier (Diagnostic and Statistical Manual [DSM]-5) and other established measures of insight in OCD.

One hundred and twenty-five outpatients with a diagnosis of OCD were assessed by Brown Assessment of Beliefs Scale (BABS) and DSM-IV's insight specifier. The insight specifier of DSM-5 was determined by item one ("conviction") of BABS. Dimensional Yale-Brown Obsessive-Compulsive Severity Scale was used to assess the frequency and severity of dimensional obsessive-compulsive (OC) symptoms.

The mean age of the participants was 31.2 (±11) years. Seventy-seven (61.6%) of the participants were men. There was a high correlation (r = 0.73) between the insight specifiers of DSM-5 and DSM-IV. Insight categories of DSM-5 had modest correlations with BABS total score and BABS-based insight categories. Significant associations were observed between the level of insight and comorbid psychotic illness, hoarding and symmetry dimensions of OC symptoms, severity of depressive, and OC symptoms. The first two associations were consistent across group comparisons (insight-groups based on DSM-IV and BABS) and correlation (with total BABS score).

Majority of the patients with OCD have good insight and application of different tools influence the assessment of insight in OCD. The DSM-5 insight specifier has strong and significant correlation with the DSM-IV's insight classification and categorization of insight by BABS.
