Analyzing Oxford Happiness Questionnaire Indonesian Version Using the Generalized Partial Credit Model

Abstract

Happiness is an essential aspect of psychological well-being, and measuring it accurately is crucial for policymakers and researchers. The Oxford Happiness Questionnaire (OHQ) is a widely used tool to assess happiness, but its validity and reliability in different cultural contexts, such as Indonesia, are yet to be determined. This research aimed to analyze the item responses of the Indonesian version of the OHQ using the Generalized Partial Credit Model (GPCM). Participants were Indonesian citizens aged between 18-40 years old, and the data were collected through an online survey. The GPCM analysis revealed that three items in the Indonesian version of the OHQ have low discriminant value. This may be due to unclear statements or insufficient information to accurately measure happiness. Despite this, the overall conclusion is that the Indonesian version of the OHQ is suitable for use as a test tool to measure overall happiness perceived by people in Indonesia. This information can be valuable for policymakers and researchers to better understand happiness levels in the country and develop strategies to improve overall well-being. In conclusion, this study provides valuable insights into the validity and reliability of the Indonesian version of the OHQ, contributing to ongoing efforts to measure happiness in diverse cultural contexts. The findings can be used to inform future research and policy decisions aimed at promoting happiness and psychological well-being in Indonesian.
