Abstract

The study was designed to examine the associations of obsessive beliefs, metacognitive beliefs and types of depression with dimensions of obsessive compulsive disorder. Using a descriptive-correlation research design, a sample of 44 consecutive patients seeking treatment at Fatemi Para-clinic in Ardebil and receiving the principal diagnosis of obsessive-compulsive disorder were recruited for the study. Participants responded to the Obsessive Beliefs Questionnaire, Meta-Cognitions Questionnaire, Zung Depression Scale and Dimensions of Obsessive-Compulsive Scale. Results revealed that 73.1%, 67.7%, 55.7%, 86.8% reported the dimensions of contamination, responsibility for harm, unacceptable thoughts and symmetry, respectively. About 90% of the patients reported comorbid moderate to severe depression, with 100% experiencing the Anhedonia type, 90.9% the Mood and Cognitive subtypes and 72.7% the Somatic subtype. Among the obsessive beliefs, beliefs about Perfectionism and Certainty correlated with all OCD dimensions, but beliefs about Responsibility and Threat Estimation and about the Importance and Thought Control correlated only with the dimensions of Responsibility for Harm and Symmetry. Of the metacognitions, Positive Beliefs about Worry were associated with¬ all the OCD dimensions, while the Need to Control Thoughts and Cognitive Self Consciousness correlated with all except the dimension of Unacceptable thoughts and Negative Beliefs about Worry correlated with the contamination and Symmetry dimensions and Beliefs about Cognitive Confidence were associated only with the dimension of Symmetry. Among the types of depression, the Mood and Somatic subtypes correlated with all the OCD dimensions while the Anhedonia and Cognitive subtype correlated only with the dimensions of responsibility and Symmetry. Obsessive beliefs about Perfectionism and the Importance of Thought Control were associated with all the subtypes of depression while beliefs about Responsibility and Threat were associated with the Mood, Anhedonia and Somatic subtypes of depression. Furthermore, negative metacognitive beliefs about worry and cognitive confidence correlated with all subtypes of depression, while beliefs about thought control and cognitive self-consciousness failed to correlate with the cognitive subtype and Positive beliefs about worry failed to correlate with the Anhedonia subtype of depression. Regression analysis revealed that the Contamination dimension of OCD was predicted by Cognitive self-consciousness and the Somatic and Mood subtypes of depression; the Responsibility dimension of OCD was predicted by obsessive beliefs about the need for thought control and metacognitive positive beliefs about worry and self-consciousness; The Unacceptable thoughts dimension of OCD was only predictable by somatic depression; the Symmetry dimension of OCD was predicted by all the obsessive beliefs and metacognitions as well as the Mood and Somatic subtype of depression.
