[ABSTRAK Studi ini bertujuan untuk mengevaluasi reliabilitas dan validitas sebuah alat ukur baru untuk mengukurObsessive Compulsive Behaviour (OCB). Alat ukur yang terdiri dari 12 item disusun dan disebarkan kepadamahasiswa PSYC3020, yang berusia 18-47 tahun di Universitas Queensland, Australia. Studi ini berhasilmenemukan bahwa alat ukur baru ini memiliki reliabilitas yang tinggi. Terdapat tiga hipotesis yang diajukandidalam studi ini untuk mengevaluasi validitas alat ukur baru ini. Hal lain juga ditemukan bahwa OCBmempunyai korelasi dengan neuroticism (r = .14, p < .05). Selain itu perbedaan rata-rata skor OCB antaraperempuan dan laki-laki juga dapat ditemukan, dimana perempuan memiliki nilai lebih tinggi dibandingkandengan laki-laki, walaupun perbedaan tersebut tidak signifikan (t(189) = 3.50, p = .001). Hubungan antara OCBdan Desirability of Control juga dievalusi di dalam studi ini. Berdasarkan hasil yang diperoleh tidak ditemukanadanya korelasi antara dua variabel tersebut (r = .07, p = .33). Dari berbagai tes yang dilakukan, dapatdisimpulkan bahwa alat ukur baru ini memiliki reliabilitas yang tinggi dengan validitas yang rendah. Perbaikandalam beberapa bagian studi perlu dilakukan guna mengembangkan alat ukur baru ini. Namun, alat ukur baru inibermanfaat untuk menangani pasien tahap remaja akhir penderita Obsessive Compulsive disorder yang tidakmendapat intervensiABSTRACT This study aimed to evaluate the reliability and the validity of the new Obsessive-Compulsive Behaviour (OCB)

measurements. Twelve items were designed and distributed to post adolesence PSYC3020 students, ranging fro

18 to 47 years, in Univeristy of Queensland. This study has brought us to the conclusion that the new scale has a

high reliability. Three hypotheses were proposed to evaluate the validity of this new scale. This study also

revealed that OCB is correlated with Neuroticism (r = .14, p < .05). Mean differences was found between male

and female participants (t(189) = 3.50, p = .001), even though it was not statistically significant, female was

found to have a higher score than males in OCB. Another correlation was tested between OCB and Desirability

of Control, however the study indicated that there is no correlation between OCB and Desirability of Control (r

= .07, p = .33). Overall result revealed that this new measure is high in reliability but low in validity. The

result also indicated that further improvements need to be done. However, this measurement contributes

positively to neglected OCD patients who are in the post adolesence stage;This study aimed to evaluate the reliability and the validity of the new Obsessive-Compulsive Behaviour (OCB)
