Independent variables: psycho-social factors
Self-esteem
The Rosenburg self-esteem scale is the most widely used self-esteem scale internationally and has been used in studies in South Africa [18, 19, 20]. Participants responded to questions of this scale about their general feelings about themselves. Scores on this 10 item self-esteem scale were summed and dichotomised across the 75th percentile to represent low (0) versus high self-esteem (1) [18].
