| Summary: | Introduction: It is undeniable that how an individual perceive their appearance brings
substantial impact on their quality of life, in terms of their social life, self-esteem and others.
The problem has increased the awareness of researchers worldwide to further explore in this
area. Body Self-Image Questionnaire is developed to measure body image perceptions;
nonetheless, due to the cultural, language and environmental differences between western and
eastern population, the validity and reliability need to be established before it can be used.
Objectives: To determine the validity and reliability of the Malay version Body Self-Image
Questionnaire among young adults in Malaysia, and to determine the invariance of the
translated Malay version of Body Self-Image Questionnaire among gender in young adults in
Malaysia.
Methods: A cross-sectional study involved web-based survey was employed in this study
among young adults in Malaysia. The study had 2 phases: Phase 1 exploratory factor analysis
(EFA) and Phase 2 confirmatory factor analysis (CFA) and multi-group analysis. Participants
were recruited using snowball sampling method. Descriptive, exploratory factor analysis,
confirmatory factor analysis and multi group analysis were applied in the statistical analysis.
Results: A total of 688 respondents participated in this study, Phase 1 EFA consisted 188
respondents; Phase 2 CFA and multi-group analysis consisted 500 respondents. For Phase 1
study, the majority of the respondents were female (67%), Malay (93.6%), single (80.9%)
and students (56.4%). Results for EFA showed factor loading of all the items ranged from
0.329 to 0.921, and communalities ranged from 0.338 to 0.780. The final measurement modelusing CFA had fit indices: CFI = 0.927, TLI = 0.913, SRMR = 0.075, RMSEA = 0.053
(90%CI: 0.047, 0.060), CF fit = 0.203. The fit indices were within the acceptable range. The
composite reliability ranged from 0.736 to 0.857. For multi group analysis, weak
measurement invariance was achieved but not strong and strict measurement invariance.
Conclusion: The results of EFA retained all the items and re-grouped them into 4 factors.
The final model for Confirmatory Factor Analysis showed good model fit, valid and reliable
after removing six items. The translated Malay version of Body Self-Image Questionnaire
consisted of four factors with 21 items. The Measurement of Invariance test’s results among
gender showed that gender is invariant in the measurement models. The questionnaire is valid
and reliable to be used among young adults in Malaysia.
