General Health Qquestionnaire-12 (GHQ-12) sebagai Instrumen Skrinning Gangguan Penyesuaian

Abstract

Adjustment Disorder (AD) is a common mental health problem in primary care setting. This study aimed to examine the validity of GHQ-12 as Adjustment Disorder screening instrument in Public Health Center (Puskesmas). The subjects were 243 adult outpatients from twenty five Puskesmas in Sleman, Yogyakarta. The prevalence of AD was 12.9%. A cronbach's Alpha of .863 (likert's scoring method), .841 (bimodal's scoring method), .832 (CGHQ's scoring method) were obtained, Sensitivity and specivity for GHQ-12 were .81 and .62 (for the optimum cutoff point ≥11 in Likert's scoring method), .81 and .57 (for the optimum cutoff point ≥2 in bimodal's scoring method), .81 and .55 (for the optimum cutoff point ≥4 in CGHQ's scoring method). Positive Likelihood Ratio and negative Likelihood Ratio for GHQ-12 were 2.12 and 0.31 (Likert's scoring method), 1.90 and 0.34 (Bimodal's scoring method), and 1.80 and 0.35 (CGHQ's scoring method). The GHQ-12 is valid and reliable in Puskesmas population, and can be employed as a screening instrumen in this population.
