This study explores whether differences in levels of psychological well-being exist between single mothers living in urban and rural areas in Selangor. Field studies were conducted on single mothers in both locations by using structured interviews. Psychological well-being questionnaires were modified by the researcher based on the Psychological well-being Scale (Ryff 1989). Psychological well-being was measured in terms of autonomy, control environment, personal development and positive relationship. This study involved 40 single mothers from Kota Damansara, Selangor and 40 single mothers from various villages in Sabak Bernam, Selangor. Data were analyzed with SPSS software using t-test. Result shows that the levels of psychological well-being between the two groups were not significantly different (t = 0.337, k>0.05). Future research can be improved by looking at single mothers from different state or district. Implications are also discussed
