Psychological Well-being Index-School Children (PWI-SC) and Psychological Well-being Index-Adult (PWI-A) have been validated and used in many countries. However, no validated PWI-SC and PWI-A in Indonesian contexts were found. The aims of this study are twofold. First, to translate the PWI-SC and PWI-A and adapt them for use in Indonesian contexts. Second, to test the validity and reliability of these PWI-SC and PWI-A. The study participants were middle school students (N = 968; 56.8% girls; 43.2% boys; M age = 13.76) and adults (N = 534; 42.1% males; 57.9% females; M age = 43.63), children and parents in this case.. They were randomly chosen from 16 middle schools in Bandung and their parents. Product moments have been used to validate PWI-SC and PWI-A. Results showed that the Indonesian version of PWI-SC and PWI-A have been translated and adapted excellently. The reliability of PWI-SC was 0.864, and the reliability of PWI-A was 0.916. PWI-SC can be used for school-aged children and adolescents, and PWI-A can be used for adults. PWI-SC and PWI-A can be used for research and practice in Indonesia.
