Responsibility attitudes and locus of control as predictors of obsessive-compulsive symtomatology : an analysis within the cognitive model

Altın, Müjgan
This study investigated the effects of responsibility attitudes, locus of control and their interactions on general obsessive-compulsive (OC) symptomatology and dimensions of OC symptoms. Research subjects consisted of 385 senior high school students from Fatih Sultan Mehmet High School in Ankara. The students were given the Turkish version of Responsibility Attitudes Scale (RAS), the Maudsley Obsessive-Compulsive Inventory (MOCI), the Locus of Control Scale (LCS), the Beck Depression Inventory (BDI), and the Trait- State Anxiety Inventory-Trait Anxiety Form (TAI). The factor analysis of MOCI revealed three-factor solution. The factors were labeled as rumination, cleanliness/meticulousness, and checking. In order to examine possible gender differences, separate analyses of variance were conducted for the variables of general obsessive-compulsive symptomatology, and symptom subtypes. Results indicated that cleaning was the most common symptom subtype, followed by rumination and checking symptoms among Turkish high school students. Related to the gender differences, females reported more OC symptoms than males. Furthermore, females received significantly higher scores for cleaning subscale than male. Hierarchical regression analyses were performed to examine the relationships between responsibility attitudes, locus of control and their interactions on general OC symptomatology and its symptom subtypes in high school student sample. It was found that there was a significantly positive relationship between responsibility attitudes and general OC symptomatology. However, locus of control was not a significant predictor of general OC symptomatology. Furthermore, results revealed that there was a significant interaction effect of responsibility attitudes with locus of control on OC symptomatology. That is, an inflated sense of responsibility and the presence of external
