Personal Growth Initiative (PGI) and Life Satisfaction: Moderating and Mediating Effect of Grit
Eyüp ÇELIK
The aim of the study is to explore the mediating and moderating effect of the characteristic of grit in the relationship between life satisfaction and personal growth initiative. Data were collected through the Turkish versions of the Personal Growth Initiative Scale, Grit Scale, and Satisfaction with Life Scale from 239 university students between the ages of 20 and 25 years (M ¼ 22.18, SD ¼.68). The findings revealed that life satisfaction was related to grit and personal growth initiative. Mediation and moderation analyses, which tested the study’s hypothesis, demonstrated that the life satisfaction and personal growth initiative relationship was partially mediated by grit, and this relationship was affected by interaction among grit and personal growth initiative. However, according to the results of the mediation and moderation analyses on the alternative mediation and moderation model, the relationship between life satisfaction and grit was partially mediated by PGI.That is, although the effect of PGI on life satisfaction is changed based on grit level, the effect of grit on life satisfaction was changed based on PGI levels. These results suggest that PGI and grit are reciprocal determinant variables on life satisfaction. Keywords: Life satisfaction, Personal growth initiative, Grit, Mediator, Moderator.
