Subjective well-being is defined as a person's cognitive and affective evaluations of his or her life that includes life satisfaction and the amount of positive and negative affect that one experiences. The aim of this study was to examine the role of HEXACO personality traits, and satisfaction of basic psychological needs in explaining subjective well-being defined by cognitive, affective and global aspects. Research was conducted via online survey on a sample of 409 participants. Aspects of subjective well-being were assessed using Satisfaction With Life Scale and Positive and Negative Affect Schedule. Basic psychological needs were assessed using Basic Need Satisfaction in General and personality traits were assessed using HEXACO-60. Three paralel hierarhichal reggression analyses were conducted, using three different criterion (satisfaction with life, affective balance, subjective well-being) and three identical predictor blocks (demografic variables, HEXACO, psychological needs). In all three analyses a significant amount od variance was explaned (43%, 61%, 65%). Needs for competence and autonomy had a significant positive contribution in predicting life satisfaction, while (negative) emotionality, extraversion, agreeableness and needs for competence and autonomy were significant predictors of affective balance. Significant positive predictors of global subjective well-being were extraversion, agreeableness and needs for competence and autonomy. Psychological needs had bigger incremental validity in explaining the variance of subjective well-being in regards to the personality traits of the HEXACO model.
