Cross-Cultural Adaptation and Psychometric Properties of the Children's Hope Scale in Indonesia: Adapting a Positive Psychosocial Tool for Adolescents With Thalassemia

Background: Hope is regarded positively as a factor in achieving a higher quality of life, particularly in chronic disease patients. Objectives: This study aims to adapt, validate, and establish the reliability of the Children's Hope Scale (CHS) questionnaire in Indonesian adolescents with thalassemia. Methods: The current study used iterative mixed methods. The data collection procedure was divided into three stages: instrument translation and cultural adaptation, validation, and reliability. The Content Validity Index (CVI) was used to assess the translated instrument's content validity, importance, contextual relevance, and acceptability of wording. Confirmatory factor analysis (CFA) was used to determine the factor structure of the CHS. Pearson correlation analyses were used to determine the associations between the two hope subscales. Cronbach's alpha coefficient and test-retest data were used to determine its reliability. Results: The CVI values ranged from 0.80 to 1.00. The CFA has shown that the two-factor model has adequate fitness factors. The Cronbach's alpha for the Indonesian CHS was 0.705, and the test reliability rate (CI 95%) was 0.81 (.73-.91). Conclusion: The CHS is a valid and reliable instrument for assessing hope in Indonesia. Additional research should be conducted to adapt and evaluate the CHS in other samples and social context in order to verify the factor consistency.
