<![CDATA[The increasing use of social media has intensified the phenomenon of online disinhibition, in which individuals tend to express their thoughts, emotions, and behaviors more freely in digital environments than in face-to-face interactions. Despite growing attention to this phenomenon, Indonesia still lacks a psychometrically validated instrument that reflects the cultural and communication characteristics of its young adult population. This study aimed to develop and evaluate an Online Disinhibition instrument for Indonesian young adults. Instrument development involved three stages: content validity assessment by four experts using the Content Validity Index (CVI), reliability testing with 30 respondents, and construct validity testing through Confirmatory Factor Analysis (CFA) involving 163 respondents. The initial instrument consisted of 40 items, of which 35 met the content validity criteria. Subsequent construct validation produced a final instrument containing 16 items representing the benign and toxic online disinhibition dimensions. The reliability analysis yielded a Cronbach’s Alpha coefficient of 0.808, indicating good internal consistency. CFA results demonstrated a good fit for the benign dimension and an acceptable fit for the toxic dimension. These findings indicate that the developed instrument possesses satisfactory psychometric properties and can be used to assess online disinhibition among Indonesian young adult social media users.]]>
