Psychometric Properties of Persian Version of the Multidimensional Body-Self Relations Questionnaire (MBSRQ) Among Iranian Elderly

Abstract

Objectives: This research aimed to investigate the psychometric properties of the Persian version of the Multidimensional Body-Self Relations Questionnaire (MBSRQ) among older Iranian people. Methods & Materials: The research method was non-experimental research that its necessary information was collected with the cross-sectional method. The statistical population comprised all older people over 60 years of age in Tehran City, Iran. The statistical sample included 1035 people who have completed the Multidimensional Body-Self Relations Questionnaire (MBSRQ). This questionnaire consists of 69 questions and 9 components. The obtained data were analyzed with confirmatory factorial analysis based on structural equations, Cronbach alpha coefficient, and intra-class correlation coefficient tests. Results: The content, face, and concurrent validity were acceptable (P<0.05). Also, result showed that the MBSRQ has acceptable fit indexes (such as RMSEA=0.042, CFI=0.903, TLI=0.978, PNFI=0.075, and PGFI=0.886). Further, the internal consistency and temporal reliability were acceptable (P<0.05). Conclusion: The Persian version of MBSRQ has acceptable reliability and validity in the Iranian elderly, and researchers, older adults, and elderly specialists can use this questionnaire for its evaluations and research.

Psychometric Properties of the Multidimensional Body–Self Relations Questionnaire—Appearance Scales (MBSRQ-AS) in Chilean Youth

“…The internal consistency obtained is consistent with the versions in Greek (α = 0.76 to 0.86) [48], Iranian (α > 0.75) [55], Brazilian (α = 0.73 to 0.90) [52], Spanish (α = 0.73 to 0.84) [51], French (α = 0.66 to 0.88) [47] and German (α = 0.78 to 0.90) [46]. Reliability has been estimated for each scale since the instrument is conceived as multidimensional, as the author points out: "Because this is a multidimensional assessment, researchers should not attempt to combine the various scales into a single measure" [41].…”

“…The psychometric properties of the Brazilian adaptation were tested with a sample of 1005 participants, highlighting that this version has the same factorial structure as the original MBSRQ-AS [52]. Likewise, adaptations and psychometric analyzes of the Persian version have been carried out in 251 Iranian women with polycystic ovary syndrome [55,56], with the aim of translating and evaluating the psychometric properties of the inventory, concluding from a confirmatory factor analysis a good fit index for the five factors, thus confirming the factor structure of the MBSRQ-AS. Additionally, exploratory factor analysis studies of the MBSRQ-AS inventory with a Malaysian population of 629 adults found a reduction in the four dimensions, even though one factor had less-than-adequate internal consistency; therefore, this factor was omitted, resulting in a solution of 3 factors and 23 items [50].…”

“…Its validity was evaluated by Brown et al [ 26 ] and reliability was reported to be 0.81. Additionally, a correlation coefficient above 0.75 for all dimensions was obtained in the Iranian context [ 27 ].…”

Correlations of Accelerometer-Measured Physical Activity with Body Image and Quality of Life among Young and Older Adults: A Pilot Study

“…Internal consistencies of the subscales of the original scale ranged from 0.76 to 0.86 [ 32 , 33 ]. The reliability of the Persian version of the MBSRQ-AS was also confirmed by a Cronbach’s alpha of the total scale of 0.83 [ 34 ] and 0.98 [ 35 ]. In this study, the Cronbach’s alpha coefficient of the total scale was 0.92.…”
