ABSTRACT
OBJECTIVES: To translate Quality of Life of the Infant (QUALIN), cross-culturally adapt the Hindi version of QUALIN (Hi-QUALIN), and evaluate its psychometric properties in children.
METHODS: This cross-sectional study was performed at the tertiary-care center in North India over 21 mo (April 2019 to January 2021). Healthy children (aged 3 to 36 mo) visiting the hospital for vaccination, minor ailments, routine health checkup, and accompanying an ill sibling were included. Children with infantile spasms in same age group were also included. Hindi translations were carried out by bilingual translators who could fluently communicate and write in Hindi and English. Standard Hindi was used to avoid the misinterpretation or misunderstanding. Discriminant and Construct validity was determined utilizing the known-groups method and factor analysis. Reliability was analysed as internal consistency and test-retest reliability.
RESULTS: Four hundred and sixty-four children were recruited through opportunity sample selection method with statistically significant difference between healthy and unhealthy children in total score of Hi-QUALIN (3-12 mo) and (13-36 mo). Finally, Hi-QUALIN (3-12 mo and 13-36 mo) consisted of 29 and 30 items constituting the five extracted factors respectively. Overall internal consistency was excellent (α = 0.92 and 0.88, respectively). Intra-class correlation coefficients (ICC) were 0.84 (95% CI: 0.78-0.89; p <0.0001) and 0.94 (95% CI: 0.93-0.96; p <0.0001) indicating excellent test-retest reliability.
CONCLUSIONS: Hi-QUALIN has good psychometric properties and can be used for health-related quality of life (HRQoL) measurement in young children.
