ABSTRACT
Edinburgh Postnatal Depression Scale [EPDS] has been used as a reliable screening tool for postpartum depression in many countries. This study aimed to assess the psychometric properties and diagnostic accuracy of the EPDS in a sample of Iranian women. Using stratified sampling 262 postpartum women [2 weeks-3 months after delivery] were selected from urban and rural health center in the city of Isfahan. They were interviewed using EPDS and Hamilton depression rating scale [HDRS]. Data were assessed using factor analysis, diagnosis analysis of receiver operating characteristic [ROC] curve, Cronbach's alpha and Pearson correlation coefficient. The age of then participants ranged 18-45 years [26.6 +/- 5.1]. Based on a cut-off point of >13 for HDRS, 18.3% of the participants. The overall reliability [Cronbach's alpha] of EPDS was 0.79. There was a significant correlation [r2=0.60, P value<0.01] between EPDS and HDRS. Two factor analysis showed that anhedonia and depression were two explanatory factors. At a cut-off point12 the sensitivity of the questionnaire was 78% [95% CI: 73%-83%] and its specificity was 75% [95% CI: 72%-78%]. The Persian version of the EPDS showed appropriate psychometric properties diagnostic accuracy index. It can be used by health system professionals for detection, assessment and treatment for mothers with post partum depression
ABSTRACT
Diabetes mellitus [DM] affects multiple aspects of life in a diabetic patient. These influences does not take two much attention in the health system. The Persian version of quality of life assessment tools in these patients is not checked. The aim of this study was to examine the normative data and some of the psychometric properties of the Persian version of quality of life questionnaire in patients with diabetes mellitus in an Iranian population. Subjects were DM patients who were referred to health centers of Isfahan city [Iran] in 2007. A total number of 120 diabetic patients were selected through stratified randomized sampling as well as equal number of matched control subjects. A demographic questionnaire, diabetes quality of life [DQOL] and WHO- quality of life [WHO-QOL] tools were administered to both groups. The total mean score of QOL was relatively low in DM patients except for the domains of worries. Using the chronbach's alpha test, the reliability of the whole questionnaire and its subscales were determined to be 0.89 and 0.51 to 0.84, respectively. Also each question showed an internal positive consistency whit the whole questionnaire except for the 8th question of the effects domain [r=-0.21]. The correlation co-efficient of co-administration of the two questionnaires and their subscales were 0.63 0.60, 0.39 and 1.18 to 3.37, respectively. The cut-off point was determined to be 2.06 based on the analysis of differentiations. The factor analysis was using the major elements and Varimax Rotation resulted in 6 factors. Our findings showed that the DQOL has proper normative data and psychometric properties in our samples. This questionnaire can be used in confidence by the health centers of Iran
