Background: Women's experience and satisfaction with childbirth care are increasingly being addressed by health care providers, managers, and policymakers. Due to need for a validated special scale for assessing satisfaction of women with preterm birth, we aimed to translate and adapt the first specific tool, Preterm Birth Experiences and Satisfaction Scale (P-BESS), into Persian language and evaluate its psychometric properties. Methods: A methodological and cross-sectional study was conducted in two tertiary levels of maternal hospitals in Tabriz. The Iranian version of the scale was developed from the original English version using forward-backward translation. After confirmation of its face and content validity, the scale was completed by 201 women who had given birth prematurely. Results: Exploratory factor analysis revealed three factors (staff professionalism and empathy, confidence in Staff, information and explanations) with eigenvalues greater than 1, explaining a total variance of 55.4%. Confirmatory factory analysis showed that the 17-item, three factor model fitted the data well: the root mean square error of approximation 0.060. There were moderate correlations between the total and sub-scales of Iranian P-BESS and overall satisfaction (r = 0.45 to 0.66), as well as need for improvement (r = -0.46 to -0.61), which confirm convergent validity. Internal consistency and test–retest reliability of the scale and its sub-scales were satisfactory (α = 0.852 to 0.922, intraclass correlation coefficient; 0.83 to 0.92). Conclusion: The Iranian version of P-BESS is a valid and reliable scale which can be used by policy makers, managers, health care providers and researchers. [ABSTRACT FROM AUTHOR]

Background: Moderate increase in physical activity (PA) may be helpful in preventing or postponing the complications of type 2 diabetes mellitus (T2DM). The aim of this study was to assess the psychometric properties of a health action process approach (HAPA)-based PA inventory amongT2DM patients. Methods: In 2015, this cross-sectional study was carried out on 203 participants recruited by convenience sampling in Isfahan, Iran. Content and face validity was confirmed by a panel of experts. The comments noted by 9 outpatients on the inventory were also investigated. Then, the items were administered to 203 T2DM patients. Construct validity was conducted using exploratory and structural equation modeling confirmatory factor analyses. Reliability was also assessed with Cronbach alpha and interclass correlation coefficient (ICC). Results: Content validity was acceptable (CVR = 0.62, CVI=0.89). Exploratory factor analysis extracted seven factors (risk- perception, action self-efficacy, outcome expectancies, maintenance self-efficacy, action and coping planning, behavioral intention, and recovery self-efficacy) explaining 82.23% of the variation. The HAPA had an acceptable fit to the observations (χ² = 3.21, df = 3, P = 0.38; RMSEA = 0.06; AGFI = 0.90; PGFI =0.12).The rangeof Cronbach alpha and ICC for the scales was about 0.63 to 0.97 and 0.862 to 0.988, respectively. Conclusion: The findings of the present study provided an initial support for the reliability and validity of the HAPA-based PA inventory among patients with T2 DM. [ABSTRACT FROM AUTHOR]

Background: At present, there are no comprehensive validated instruments for measuring adolescents' beliefs regarding tobacco smoking in the Iranian society. This study aimed to evaluate the validity, reliability and feasibility of the belief- based tobacco smoking scale using the Theory of Planned Behavior's (TPB) constructs as a theoretical framework. Methods: This cross-sectional validation study was carried out on 410 male adolescents of Hamadan, west of Iran, recruited through multi-stage random sampling method. Reliability was assessed by internal consistency and Intraclass Correlation Coefficient (ICC). In addition, Confirmatory Factor Analyses (CFA) and Exploratory Factor Analyses (EFA) were performed to test construct validity. Content validity was examined using Content Validity Index (CVI) and Content Validity Ratio (CVR). Results: Results obtained from factor analysis showed that the data was fit to the model (χ²=391.43, P<0.001) and TPB consisted of 22 items measuring seven components which explaining 69.7% of the common variance. The mean scores for the CVI and CVR were 0.89 and 0.80; respectively. Additional analyses indicated acceptable results for internal consistency reliability values ranging from 0.55 to 0.92. Conclusion: The belief-based tobacco smoking questionnaire is a reliable and valid instrument and now is acceptable and suitable and can be used in future studies. [ABSTRACT FROM AUTHOR]
