Psychometric properties of the Persian version of postpartum distress measure scale.

ABSTRACT: BACKGROUND:The purpose of the present study was to determine psychometric properties of the Persian version of Postpartum Distress Measure Scale (PDM Scale). METHODS:In this psychometric explorative study, the data were collected using a questionnaire containing demographic information, PDM Scale, and Depression and Anxiety Stress Scale-21 (DASS-21). The content, face and construct validity of the questionnaire was examined with participation of ten experts, 10 and 150 women referring to health care centers, who were under common care during their postpartum period, respectively. The concurrent validity of the tool was evaluated using DASS-21. The reliability of the items was evaluated with the participation of 30 women, calculating Cronbach's alpha coefficient and intra-class correlation coefficient. RESULTS:The Content Validity Index, Content Validity Ratio and Impact Score of the Persian version of the PDM were 0.94, 0.73, and 2.97, respectively. The ten items of the questionnaire were loaded in two factors (general distress and obsessive compulsive symptoms subscale). Those two factors explained 50.78% of the total variance of women's distress. Internal consistency of the items and stability of the results were confirmed by Cronbach's alpha of 0.72 and Intra-class correlation coefficient of 0.75. CONCLUSION:According to the study results, the Persian version of PDM Scale has acceptable psychometric properties. Care providers and researchers can use it as a tool for screening anxiety, depression and obsessive-compulsive disorder in women.

Project description:BACKGROUND:To measure the severity of menopausal complaints and determine the pattern of menopausal symptoms, a valid and reliable instrument is needed in women's healthcare. The Menopause Rating Scale (MRS) is one of the best-known tools in response to the lack of standardized scales. The purpose of this study was to examine the psychometric properties of the MRS in an Iranian example. METHODS:Participants were randomly selected from women referred to healthcare centers in Miandoab, West Azerbaijan, Iran. A total of 330 questionnaires were completed (response rate of 96.9%). Two samples were considered for analysis in the validation process. An exploratory factor analysis (EFA) was conducted on the first sample (n1?=?165), and a confirmatory factor analysis (CFA) was done using a second study sample (n2?=?165). The psychometric properties process was concluded with assessment of internal consistency and test-retest reliability. RESULTS:The EFA with Principal Component Analysis extracted three factors explaining 75.47% cumulative variance. The CFA confirmed a three-factor structure of the 11-items MRS. All fit indices proved to be satisfactory. The relative chi-square (?2/df) was 3.686 (p?<?.001). The Root Mean Square Error of Approximation (RMSEA) of the model was .04 (90% CI?=?.105-.150). All comparative indices of the model, including the Comparative Fit Index, Normed Fit Index, and Relative Fit Index, were more than .80 (.90, .87, and .80, respectively). For the overall scale, Cronbach's alpha was .931, whereas the alpha for the subscales ranged from 0.705-0.950. The intraclass correlation was .91 (95% CI?=?.89-.93), p?<?0.001. CONCLUSION:The results of the study indicate that the Persian model of the MRS is a valid and reliable scale. As a screening tool, the Persian MRS could be used to identify the pattern of symptoms among menopausal, premenopausal, and postmenopausal women to care for and educate them on how to identify and treat the symptoms.

Project description:BackgroundA gluten-free diet (GFD) is the only effective treatment for celiac patients and assessing adherence to this diet is important. Celiac disease Adherence Test (CDAT) is a valid English-language questionnaire that is used for assessing the adherence to the GFD. In the present study, we aimed to translate the CDAT questionnaire in Persian and evaluate its validity and reliability.MethodsIn the present cross-sectional study, CDAT was translated and back-translated by three bilingual professional translators. Content validity was evaluated by 12 gastroenterologists and nutritionists. To assess the construct validity, 230 patients with celiac disease were randomly selected from the national celiac disease registry database. Internal consistency of the items and test-retest reliability were assessed by Cronbach's alpha and Intraclass Correlation Coefficient (ICC). To assess the convergent validity of the questionnaire, the correlation coefficient between the CDAT score and anti-tissue transglutaminase immunoglobulin A (anti-t-TG-IgA) titer was assessed.ResultsThe content validity index, content validity ratio, and impact score of the Persian version of CDAT (Pv-CDAT) were 0.97, 0.95, and 4.61 respectively. Three significant factors were extracted and according to the confirmatory factor analysis the three-factor model had adequate fitness (chi-square p-value of 0.74, root mean error of approximation: 0.001 [95% CI: 0.001-0.083], comparative fit index: 1, standardized root mean squared residual: 0.04, and coefficient of determination: 0.78). The questionnaire had good feasibility with the floor effect of 3.1% and the ceiling effect of 0.4%. Moreover, it has high internal consistency (Cronbach-alpha: 0.71) and test-retest reliability (ICC: 0.78). The correlations between CDAT categories and anti-tTG-IgA categories showed a significant correlation between the two tests (r = 0.53; P < 0.001).ConclusionsThe results of the present study showed that the Pv-CDAT questionnaire with high validity, reliability, and internal consistency can be used for assessing adherence to the GFD in adult celiac patients in Iran.

Project description:BackgroundPerson-centered care is a valuable approach to improve the quality of care of the elderly and is a starting point for maintaining the dignity of people needing care.ObjectivesThis study aimed at translation, cultural adaptation, and validation of the Persian version of the Person-centered Climate Questionnaire-Patient questionnaire in elderly patients admitted to the Eastern Guilan hospitals from 2017-2018.DesignThis research was a cross-sectional study. The Persian version of Person-centered Climate Questionnaire -Patient version was completed by 200 older adults admitted to different wards of the hospitals. They were selected through convenient sampling. Data were collected in 5 hospitals affiliated to Guilan University of Medical Sciences, East of Guilan located in the north of Iran, from November 2017 to February 2018.MethodsThis study was carried out in two phases. In the first phase, the original questionnaire with 17 items was translated from English into Persian using Forward-Backward translation method. In the second phase, the psychometric properties of the questionnaire were evaluated using face, content, and construct validity, as well as reliability (internal consistency and stability). Data were analyzed via SPSS software v.16.ResultsThe results of exploratory factor analysis (EFA) led to retaining 17 items with three factors of "Safety", "Hospitality", and "Everydayness" which explained 47.69% of the total variance. Cronbach's alpha coefficient was calculated for each factor (0.85, 0.70, and 0.64, respectively) as well as the whole instrument (0.85), to ensure internal consistency. Stability was confirmed by calculating the intra-class correlation coefficient as 0.99.ConclusionsThe current study found support for assessing the person-centered climate from the perspective of the elderly patients by using the Persian version of the Person-centered Climate Questionnaire-Patient that has an appropriate cultural adaptation, validity, and reliability.
