I evaluated the predictive effects of subjective happiness, forgiveness, and ruminative thought style on life satisfaction with a sample of 380 Turkish university students aged between 18 and 25 years. Participants completed the Satisfaction with Life Scale, the Subjective Happiness Scale, the Trait Forgiveness Scale, and the Ruminative Thought Style Scale. Results of correlation and multiple regression analyses revealed that forgiveness and subjective happiness were positively correlated with life satisfaction, and rumination was negatively correlated with life satisfaction. The multiple regression analyses also showed that subjective happiness and forgiveness positively predicted life satisfaction, and rumination negatively predicted life satisfaction. Results are discussed in light of the related literature.
