GRATITUDE DAN SPIRITUAL WELL-BEING SEBAGAI MEDIATOR DALAM PENGARUH INTRUSIVE RUMINATION TERHADAP POSTTRAUMATIC GROWTH PADA PENYINTAS BENCANA GEMPA BUMI BANTUL TAHUN 2006NIM.: 22107010064Izad Tiara Najah Putri SauthorTraumatic events such as earthquakes can cause survivors to experience psychological problems, including anxiety, depression, and PTSD. However, traumatic experiences may also become a starting point for positive psychological changes, known as post-traumatic growth. This study is important to broaden the understanding of earthquake survivors by not only focusing on the negative impacts of trauma but also identifying factors that may support post-traumatic growth. The aim of this study was to examine the roles of gratitude and spiritual well-being as mediators in the effect of intrusive rumination on post-traumatic growth among survivors of the 2006 Gempa bumi Yogyakarta 2006. This study employed a quantitative explanatory approach with a cross-sectional design. Participants were selected using purposive sampling and data were collected through questionnaires. Data analysis was conducted using path analysis with a parallel mediation model. The results showed that intrusive rumination had a positive effect on post-traumatic growth (Estimate = 0.194; p<0.001). Separate mediation analysis showed significant indirect effects through gratitude (p<0.001) and spiritual well-being (p = 0.003). Simultaneous mediation analysis also indicated significant indirect effects for gratitude (p = 0.033) and spiritual well-being (p = 0.001), while the direct effect remained significant (p<0.001), indicating partial mediation. This study contributes to disaster trauma psychology by providing evidence that gratitude and spiritual well-being may support recovery and psychological growth among disaster survivors.150 Psikologi2026-05-12UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS ILMU SOSIAL DAN HUMANIORAThesis
