Penelitian ini bertujuan untuk mengetahui hubungan antara general self-efficacy dan resilience dengan organizational citizenship behavior (OCB) serta efektivitas dari intervensi 'Self Improvement Program' dalam upaya meningkatkan general self-efficacy dan resilience. Responden penelitian berjumlah 38 orang AoC volunteer di PT X. Hasil uji korelasi menunjukkan bahwa terdapat hubungan positif dan signifikan antara general self-efficacy dengan OCB (r_s = .557, p < .01). Resilience pun terbukti memiliki hubungan yang positif dan signifikan dengan  OCB (r_s = .553, p < .01). Selanjutnya, peneliti merancang intervensi yang tepat untuk menangani masalah organisasi dengan memberikan 'Self Improvement Program' kepada 5 orang sampel AoC. Berdasarkan hasil uji perbedaan antara sebelum dan setelah intervensi diberikan, terdapat perubahan skor yang signifikan pada general self efficacy (Z = -2,023, p < .05), resilience ( (Z = -2,023, p < .05), dan OCB (Z = -2,023, p < .05).

The intervention was design to solve organizational problems by giving the 'Self Improvement Program' to 5 samples of AoC. The difference test results demonstrated a significant score change in general self-efficacy  (Z = -2,023, p < .05), resilience ( (Z = -2,023, p < .05), and OCB (Z = -2,023, p < .05).
