[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

[Cultural adaptation, validity and reliability of Persian version of experience of caregiving inventory in families of patients with severe mental disorders]

This study aims to evaluate the cultural adaptation, validity and reliability of the Persian version of Experience of Caregiving Inventory [ECI] in families of patients with severe mental disorders. After the translation and cultural adaptation of ECI, 225 family members of patients with severe mental disorders completed the ECI, the General Health Questionnaire [GHQ-28] and a demographic questionnaire. The Split half test was used to assess reliability. To determine internal consistency, Cronbach's alpha test and the concurrent validity was calculated by Pearson's correlation between the GHQ-28 and the ECI total negative score. Reliability of the Inventory as assessed by the Spearman-Brown correlation coefficient was 0.80. The range of the Cronbach's alpha for each subscale, total negative score and total positive score was 0.51 to 0.90. Pearson's correlation between the GHQ-28 score and the total negative score was 0.37 [p<0.01]. The Persian version of the ECI has good reliability and validity for family members of patients with severe mental disorders
