The aim of the study was to analyze the relationships between the propensity to forgive and life satisfaction in different age groups. Polish versions of the Heartland Forgiveness Scale (adapted by Kaleta, Mroz, and Guzewicz, 2016) and of The Satisfaction with Life Scale by Diener et al. (SWLS, 1985) adapted by Juczynski (2012), were used. The sample consisted of 436 individuals aged 19-67. The analyses were performed separately for all age groups. Positive and negative dimensions of forgiveness of self, of others, and of situations beyond anyone's,control were considered. The results revealed relationships between different aspects of the disposition to forgive and life satisfaction across the entire sample. In addition, significant positive correlations between positive and negative aspects of forgiveness and life satisfaction were observed in individuals aged 19-30 and 41-50. On the other hand, in the group of respondents aged 31-40 a significant positive relationship between reduced unforgiveness and satisfaction with life, whereas in the group aged 50 and over, between positive forgiveness and life satisfaction, were revealed.
