This study aimed to identify the relationship between the belief system and emotional well-being of single mothers in Kluang, Johor. This study involved 58 respondents using the purposive sampling technique. Questionnaires were used to identify the emotional well-being and respondents' belief system. Data were analysed using Statistical Package for the Social Science (SPSS 19.0). Descriptive statistics in the form of percentage, mean, and inferential statistics, namely, ‘Pearson r’ correlation analysis was used to identify the relationship between single mothers’ emotions and their belief system. Results of the study found the single mothers’ emotional well-being to be moderate (M = 23:56, S.D = 6.62) and their belief system to be high (M = 37.55, S.D = 8.22). In addition, the study also showed a significant difference between the single mothers’ age, reason for becoming single mothers, occupation, number of dependent children and family members, in relation to the single mothers’ belief system and emotional well-being. However, there was no significant difference in the relationship between their level of education and belief system. The study also showed a moderate correlation between the two variables (r = 0.665, p = 0.000). Implications of the study are discussed and further research can be carried out on samples who have recently experienced a separation or divorce, to assess the short term and long term impact.
