[Multi-dimensional group therapy for obsessive-compulsive disorder]

The purpose of the current study was to assess the effectiveness of multi-dimensional group therapy for symptoms of obsessive-compulsive disorder [OCD]. Among 53 patients with OCD referred to a hospital in Tehran, 12 patients to experimental group and 12 patients to control group were assigned. Not being affected to major depression, bipolar disorder and personality disorder was approved. The data was gathered using clinical interview based on Diagnostic and Statistical Manual of Mental Disorders, 4[th] edition, Text Revision [DSM-IV-TR], Cattel Personality Test and Yale-Brown Obsessive-Compulsive Scale [Y-BOCS]. For evaluating the symptoms severity, Y-BOCS were executed before, during and after intervention. Multi-dimensional group therapy was performed in thirty 2-hour sessions based on Clark Therapeutic Program in accordance with Lazarus multi-dimensional treatment and Islamic-Iranian culture. The severity of symptoms subscale decreased during treatment [p<0.001]. Designed multi-dimensional group therapy based on Islamic culture was effective for treatment of OCD symptoms

[Reliability and validity of the Persian version of the Yale-Brown obsessive-compulsive scale [y-bocs]]

The aim was to evaluate the validity and reliability of the persian version of Yale-Brown Obsessive- Compulsive Scale [Y-BOCS]. The sum of 140 patients with obsessive-compulsive disorder [OCD] and 30 individual participants without OCD were selected via convenient sampling as experimental and control groups respectively. Data gathering was done using Y-BOCS, Structured Clinical Interview for DSM-IV axis-I disorders [SCID-I] and Symptom Checklist-90-Revised Obsessive-Compulsive Symptoms [SCL-90-R-OCS]. Reliability coefficients were calculated by Cronbach's alpha, split-half, and test-retest reliability. For validity assessment, concurrent criterion-related validity in correlation with SCID-I and SCL-90-R-OCS, and construct validity [exploratory factor analysis] were executed. In order to normalize the Y-BOCS after insuring that the distribution is normal and does not have kurtosis and skewness, mean and standard deviation were used as the most appropriate central tendencies and deviation. Optimal levels of internal consistency scores [symptom checklist 0.97, severity scale 0.95] split-half reliability [symptom checklist 0.93, severity scale 0.89], and test-retest reliability [0.99] were calculated. Concurrent reliability were examined and established by correlating the Y-BOCS with the SCL-90-R-OCS and SCID-I. Exploratory factor analysis was also examined, which indicated three factors for symptom checklist scale and two factors for symptom severity scale. Cutoff point value [9] was also determined. The results supported satisfactory validity and reliability of translated form of Yale-brown Obsessive-Compulsive Scale for research and clinical diagnostic applications
