[ABSTRAK
Penelitian ini bertujuan untuk mengembangkan skala baru dalam mengukur perilaku obsesif-kompulsif.Survei diberikan kepada 194 mahasiswa program sarjana S1 dari University of Queensland. Setelah semua datatelah terkumpul dan diselesaikan, skala baru yang telah dikembangkan dari perilaku obsesif-kompulsif pun diujireliabilitas, Item Discrimination Index, dan validitas dalam skala hubungannya dengan variabel lain yakni locusof control, status hubungan romantis, dan daftar Obsessive-Compulsive Inventory (OCI-R) baru yang telahdirevisi. Skala obsesif-kompulsif baru yang telah dikembangkan ternyata memiliki reliabilitas yang tinggi diantara butir-butir lainnya. Item Discrimination Index menunjukkan bahwa tiap butir skala bisa dibedakan denganbaik, dengan hanya membutuhkan tiga butir untuk diubah penulisan katanya (M = 32.40, SD = 8.17). Ditemukanhubungan antara butir skala obsesif-kompulsif dengan locus of control (r(189) = .18, p = .013) dan variabel OCIRyang bertugas untuk memvalidasi (r(189) = .37, p < .001), tetapi tidak ditemukan hubungan antara obsesifkompulsifdengan status hubungan romatis (r(189) = .08, ns.). Skala butir yang baru dikembangkan padapenelitian ini terbukti dapat berlaku untuk setting non-klinis serta memerlukan penelitian lebih lanjut untukmemvalidasi penggunaannya dengan variabel lain yang ada.ABSTRACT The present study looked to develop a new scale in measuring obsessive-compulsive behaviour.

Surveys were administered to 194 undergraduate university students of The University of Queensland to

complete. After all the data have been gathered, the newly developed scale of OCB was tested on its reliability,

Item Discrimination Index, and validity in conjunction with other variables of locus of control, relationship

status, and OCI-R. The newly developed OCB scale proved to have high reliability among its items and good

discriminating index with only three items that need rewording (M = 32.40, SD = 8.17). Items demonstrated

relationship with locus of control (r(189) = .18, p = .013) and OCI-R validating variables (r(189) = .37, p <

.001), but none was found with relationship status (r(189) = .08, ns.). This newly developed scale proved to be

applicable to non-clinical setting and need further researches to validate its use with other existing variables., The present study looked to develop a new scale in measuring obsessive-compulsive behaviour.
