<![CDATA[Developing Personal Growth Initiative (PGI) enables students to intentionally engage in self-development in today's dynamic environment. This study aimed to examine the effectiveness of Pelatihan Pertumbuhan Pribadi (Personal Growth Training), a training program developed based on Intentional Growth Training, in increasing PGI among Indonesian university students in both short-term and one-year follow-up assessments. The program consists of psychoeducation on PGI and structured growth activities that have been shown to enhance personal growth. This preliminary study employed a quasi-experimental one-group pretest–posttest with follow-up design and involved 12 undergraduate students from Sriwijaya University who were categorized as having moderate PGI and completed all intervention sessions. PGI was measured using the Personal Growth Initiative Scale II, and the data were analyzed using paired-sample t-tests. The results indicated a significant increase in PGI from pretest to posttest (t = 6.159, p < 0.001, d = 1.778) and from pretest to follow-up (t = 5.191, p < 0.001, d = 1.565), while no significant difference was found between posttest and follow-up scores (t = −0.668, p > 0.05, d = 0.201). These findings suggest that participation in Personal Growth Training was associated with increased PGI scores, with improvements maintained at both the posttest and one-year follow-up assessments. Further studies using randomized controlled trial designs are recommended to strengthen the evidence.]]>
