This study aims to develop and assess the psychometric properties of the ‘Inventori Gangguan Bipolar (IGB)’ or the Bipolar Disorder Inventory, a tool designed to measure the severity of bipolar disorder among individuals. The IGB was constructed based on the principles outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-V, 2013) by the American Psychiatric Association (APA). The inventory comprises 18 negative items divided into three subscales: Manic, Hypomanic, and Depressive, each containing six items. Content validity was evaluated by a panel of seven experts, consisting of three academic lecturers and four practitioners (two registered counselors and two clinical psychologists), resulting in a high content validity index (CVI) of 0.944 (94.4%). Reliability testing, performed on a sample of 50 individuals using Cronbach's alpha, yielded a moderate-to-high overall reliability score of 0.800, with subscale scores ranging from 0.769 to 0.807. These findings indicate that the IGB is a valid and reliable tool for the initial screening and assessment of bipolar disorder symptoms. While suitable for use in guidance and counseling practices, further research is recommended to enhance the instrument's robustness and applicability across diverse populations in Malaysia.
