<r2r:ml lang="en"><p class="abstract" dir="ltr">Several authors have studied the relationship between well-being and values, highlighting that it is partially determined by personal values that prevail in social environment (Basabe et al., 2002; Lima &amp; Novo, 2006; Paéz &amp; Zubieta, 2004; Sagiv, Roccas &amp; Hazan, 2004; Sagiv &amp; Schwartz, 2000). Such studies are usually oriented to subjective well-being, while there is a lack of researches focused on psychological and social well-being dimensions. In order to analyze the mediated role of values in psychological and social well-being, a correlational study was carried out- non experimental transversal design. A convenience sample was used composed by 1062 participants (33.6% males- 66.4% females, age<span style="font-family:'Cambria Math',serif;"> </span>M<span style="font-family:'Cambria Math',serif;"> </span>=26.73;<span style="font-family:'Cambria Math',serif;"> </span>SD=10.01)from Argentina.<br />Based on previous correlation analysis, eleven regressions (stepwise method) were carried out introducing values as psychological and social well-being dimensions predictors. Self-transcendence and openness to change values had significant betas in almost all psychological and social well-being dimensions while conservation values had a negative effect on positive relations with others, autonomy, personal growth, social acceptance and social coherence and self-promotion values on autonomy, environmental mastery, personal growth and social contribution.</p></r2r:ml>
