Meningkatan Rasa Percaya Diri Melalui Bimbingan Kelompok Menggunakan Media Kartu Afirmasi pada Siswa SMA

Abstract

Self-confidence is essential for students to function optimally in academic and social spheres. This study aimed to examine the effectiveness of affirmation cards as a medium in group guidance services to enhance the self-confidence of Grade X students at SMAN 1 Papar. A quantitative approach with a One-Group Pretest-Posttest design was employed. The sample consisted of 10 students selected through purposive sampling based on self-confidence scale results and Guidance and Counseling teacher recommendations. Data were collected using a validated and reliable self-confidence scale administered before and after five group guidance sessions utilizing affirmation cards. Data were analyzed using descriptive statistics, the Paired Sample t-Test, and the N-Gain test with IBM SPSS Statistics. The findings indicated that the mean self-confidence score increased from 118.60 to 167.00. The Paired Sample t-Test showed a significant difference (p = 0.000 < 0.05), while the N-Gain score was 0.6256 (moderate), indicating a 62.56% improvement. These results demonstrate that affirmation cards are effective in enhancing students’ self-confidence.
