This study analyzed response inhibition, cognitive flexibility and working memory in three groups of patients diagnosed with obsessive-compulsive disorder, social anxiety disorder and generalized anxiety disorder, considering some variables that may influence results (nonverbal reasoning, comorbidity, use of pharmacotherapy). Neuropsychological measures were completed using a computerized Wisconsin card sorting test, Stroop color word test, go/no-go task, digits and Corsi. Significant differences were obtained among groups in cognitive flexibility and working memory variables. The obsessive-compulsive disorder (OCD) group showed the worst results. The social anxiety disorder group obtained greater effect sizes in visuospatial memory. However, significant differences between groups in visuospatial memory were no longer present when nonverbal reasoning was controlled. Comorbidity influenced interference in the OCD and generalized anxiety disorder (GAD) groups. In addition, the executive functions were differently influenced by the level of obsessions and anxiety, and the use of pharmacotherapy. Study limitations include a non-random selection of participants, modest sample size and design type (cross-sectional). The OCD group showed the worst results in flexibility cognitive and verbal working memory. Comorbidity, use of pharmacotherapy and level anxiety and obsessions were variables influencing the performance of executive functions.

There is a growing interest in designing instruments to assess obsessive-compulsive symptoms in children. The Obsessive-Compulsive Inventory-Child Version (OCI-CV) has showed to be a valid in the evaluation of OCD in clinical and nonclinical populations. The main goal in this study was to analyze factor structure and psychometric properties of the OCI-CV in a community Spanish sample. Data were collected from 914 children/adolescents with a mean age of 13.01 (SD = 1.96; Males = 51.3%). Exploratory factor analysis was carried out in order to study the internal structure of the OCI-CV Spanish version. Further, internal consistency, test-retest reliability, and convergent and discriminant validity of the total score and the factors obtained were examined. Finally, age and gender differences were also explored. Exploratory factor analysis yielded a similar structure to the original OCI-CV with the following six factors: Washing/Checking, Obsession, Ordering, Doubting, Neutralizing, and Hoarding. The internal consistency was strong for the total score, but moderate for the subscales. The Spanish version of the OCI-CV showed evidences of test-retest reliability and convergent and discriminant validity. The Spanish version of the OCI-CV is an instrument with adequate psychometric properties to assess obsessions and compulsions in Spanish children/adolescents.
