Background: Self-care during Coronavirus Disease 2019 (COVID-19) helps people follow self-care strategies to reduce the spread of the virus. To control the disease, people need to engage in self-care behaviors, which should be investigated by a valid and reliable instrument to yield valid and credible results.
Objectives: This study aimed to validate the Persian version of the Self-Care in COVID-19 Scale (SCOVID Scale).
Methods: The sample included 582 participants from Tehrans general population, selected through convenience sampling in 2021. They were divided into two groups, one for exploratory factor analysis (EFA) and the other for confirmatory factor analysis (CFA). Cronbachs alpha coefficient and McDonalds omega were used to assess the internal consistency. Standard error of measurement and the interclass correlation coefficient were also employed to examine absolute and relative stability, respectively.
Results: In the EFA, three factors, including Precaution, Routine Activities, and Lifestyle, were extracted, explaining 32.31% of the total variance in COVID-19 self-care. Internal consistency of the whole scale using both Cronbachs alpha coefficient and McDonalds omega was above 0.7. The goodness of fit indices of the second-order CFA were in the acceptable range (x2=262.365, df=82, P<0.001, RMSEA=0.062, PCFI=0.725, PNFI=0.703, IFI=0.930, and the CFI=0.929).
Conclusion: The Persian version of the SCOVID Scale is a valid and reliable instrument that can be used in studies on COVID-19.

Background: Morbid obesity negatively affects all aspects of quality of life (QOL); therefore, the assessment of QOL can be a useful criterion to evaluate obesity outcome.
Objectives: The present study aimed to design a QOL questionnaire in morbid obesity and assess its validation features.
Methods: This sequential-exploratory mixed-methods study was conducted in both qualitative and quantitative stages. The qualitative stage was carried out through 20 semi-structured interviews with morbidly obese people. Furthermore, the initial items of the questionnaire were obtained by a review of related literature. In the next stage, face, content, and construct validity were assessed. The construct validity was examined by exploratory factor analysis with 319 people. Moreover, Cronbachs alpha and test-retest correlation coefficient were calculated to evaluate the reliability of the questionnaire. Furthermore, confirmatory factor analysis was assessed.
Results: Based on the results of the quantitative stage, an 80-item pool was extracted. The exploratory factor analysis yielded six factors that explained 50.62% of the variance. The factors of one to six were as follows: self-dissatisfaction (15 items), functional disorders (7 items), spiro-mental experiences (11 items), perso-social isolation (7 items), physical changes (7 items), and financial pressure (3 items). The final Cronbachs alpha coefficient of the 50-item questionnaire was calculated at 0.94. Moreover, the intra-class correlation coefficient between the test and retest scores was estimated at 0.97. All indicators of confirmatory factor analysis demonstrated that goodness of fit was acceptable for each factor. Furthermore, this questionnaire had appropriate interpretability, feasibility, and did not have any floor and ceiling effects.
Conclusion: This valid and reliable questionnaire can be used as a suitable measurement tool for assessing the QOL of morbidly obese people in Iran and other countries with similar cultural features. This questionnaire can improve the quality of future clinical research on obesity. In addition, health care providers can perform a peculiar role in the provision of efficient services to patients to prevent obesity and its associated complications.
