Abstract
BackgroundThis study examined the psychometric properties of the Malay version of the decisional balance (DB-M) for exercise (i.e. perceived benefits and perceived barriers) using a cross-sectional design. Also, this study assessed the measurement and structural invariance of the DB-M across gender.MethodsThe study sample consisted of 750 students (female: 51.7%, male: 48.3%), with a mean age of 20.2 years (SD = 1.2). Decision balance (DB) scale was assessed with the 10-item DB-M. Standard forward-backward translation was performed to translate the English version of the DB into Malay version (DB-M).ResultsThe confirmatory factor analysis (CFA) results based on the hypothesised measurement model of two factors and ten items demonstrated adequate factor structure after the addition of some correlated item residuals (comparative fit index (CFI) = .979, Tucker and Lewis index (TLI) = .969, standardised root mean square residual (SRMR) = .037, root mean square error of approximation (RMSEA) = .047). The construct reliability and average variance extracted values were .850 and .839, and .542 and .538, for perceived benefits and perceived barriers, respectively. Meanwhile, the Cronbach’s alpha was .857 and .859, and the intraclass correlation coefficient for test-retest reliability was .979 and .960 for perceived benefits and perceived barriers respectively. The findings provided evidence for measurement invariance of DB-M for the male and female samples. The final CFA model fit the data well for both male sample (CFI = .975, TLI = .964, SRMR = .040, RMSEA = .052) and female sample (CFI = .965, TLI = .949, SRMR = .044, RMSEA = .058).ConclusionsThe translated version of the DB-M was valid and reliable for assessing the level of perceived benefits and perceived barriers in exercise among university students in Malaysia.
Highlights
It has been widely reported that participation in regular physical activity can significantly reduce the risk of hypertension, diabetes, cardiovascular diseases, obesity, overall fitness, mental wellness, and quality of life [1, 2]

Summary
It has been widely reported that participation in regular physical activity can significantly reduce the risk of hypertension, diabetes, cardiovascular diseases, obesity, overall fitness, mental wellness, and quality of life [1, 2]. The TTM is a collective psychological framework that aims to demonstrate deliberate health behaviour choice and sustenance as a process that transpires over time as a function of behavioural history and motivation [7]. This model illustrates how people move dynamically through stages of behavioural change [8]. Many studies have used the TTM or Stages of Behavioural Change (SBC) Model to develop interventions to promote physical activity [9, 10]. This study assessed the measurement and structural invariance of the DB-M across gender
