Ryff's multidimensional model of psychological well-being has allowed the evaluation of the construct from six dimensions (self-acceptance, positive relations with others, autonomy, environmental mastery, personal growth and purpose in life).There is little research on the relationship between psychological well-being and social support, specially with college students.In addition, there are few studies on sex differences and the level of education in relation to psychological well-being and social support.To assess the relationship between the level of psychological well-being and social support Ryff's Psychological Well-Being Scales and The MOS Social Support Questionnaire were used.We recruited a sample of 768 college undergraduates and graduates by availability.The results show low to moderate correlations between the Ryff Psychological Well-Being Scales and Social Support subscales.Women exhibited significantly higher means on sub-scales of personal growth and purpose in life.A one-way ANOVA analysis and its respective post-hoc test, indicate that there are significant differences between undergraduate and doctoral levels for three of the dependent variables examined.
