Validation of the Farsi version of the medical outcomes study-social support survey for mammography

Abstract

BackgroundSocial support can provide psychosocial benefits to promote positive health behaviors such as mammography screening. The purpose of this study was to assess the psychometric properties of the Mammography Social Support (MSS) scale among Iranian woman.MethodsParticipants were selected from women referring to healthcare centers in Sanandaj, Iran. A total of 434 questionnaires were completed (response rate 91%). The study sample for study 1 included 204 participants for the Exploratory Factor Analysis (EFA). Construct validity was determined by confirmatory factor analysis (CFA) using a study sample of 230 women in study 2. The reliability coefficient for each scale was calculated using Cronbach’s alpha, corrected item-total correlations and test-retest respectively.ResultsCFA affirmed the three-factor structure of the MSS in measuring the functional dimensions of social support for mammography behavior consisting of 19 items. Initial results of the CFA did not fully support the proposed three-factor model. After the model was modified, the fit indices indicated, x2 was 2.3, Comparative Fit Index (CFI) = 0.96, Tucker- Lewis Index (TLI) = 0.95 providing a strong fit to the data. Cronbach’s alphas for the subscales ranged from 0.82 and 0.90, whereas the alpha for the overall scale was 0.91. The 2-week test-retest reliability of MSS was 0.95.ConclusionThis study provides evidence for the psychometric properties to support the Farsi version of the MSS when applied to Iranian women. Exploring the three-factor model in relation to related concepts is suggested for future studies.

The Medical Outcome Study Social Support Survey (MOS‐SSS): A psychometric systematic review

“…Details about translators are limited. Eleven studies reported their back translation process; three studies did not (Khazaee‐Pool et al, 2018; Norhayati et al, 2015; Yilmaz & Bozo, 2019). The number of people involved in the translation and back‐translation process varied from two individuals to two groups of translators.…”

“…Three studies did not report their translation equivalence evaluation (Alaloul et al, 2021; Nicolaou et al, 2015; Norhayati et al, 2015). Three studies had one person compare two English versions (Huang et al, 2021; Khazaee‐Pool et al, 2018; Yilmaz & Bozo, 2019). Seven studies reported that a group compared two English versions (Bavarsad et al, 2021; Dafaalla et al, 2016; Giangrasso & Casale, 2014; Khuong et al, 2018; Saddki et al, 2017; Shyu et al, 2006; Yu et al, 2004).…”

“…Ten studies performed test–retest analysis. Two did not report the method to examine test–retest reliability (Khazaee‐Pool et al, 2018; Yilmaz & Bozo, 2019). Five studies calculated test–retest reliability using the intra‐correlation coefficient (ICC).…”

Psychological impact of COVID-19 on health-care workers: A multicenter cross-sectional study

“…MOS-SSS is developed in 1991 by Sherburne and Stewart to measure the sense of social support[ 20 ] and validated in Persian. [ 21 ] The questionnaire contains 19 items and measures four dimensions: tangible support, emotional and informational support, affectionate support, and positive social interaction. The scoring is on the Likert scale (1: none of the time to 5: all of the time), and the total score is 19–95.…”
