Validity and Reliability of Revised Impact of Family Scale in Primary Care Giver of Cleft Lip and Cleft Palate Children in West Bengal, India the Hospital Context

Aim: The aim of the study was to check the validity and reliability of revised impact of family scale (RIOFS) in Indian setting among Bengali population in parents or primary care giver of cleft lip and cleft palate children who were hospitalised for their treatment in comprehensive cleft care centre, Kolkata, West Bengal, India.

Materials and Methods: This study was conducted in a comprehensive cleft care centre which is located at Howrah, Kolkata. Original RIOFS (2019) questionnaire was the assessment tool in this study. The original questionnaire was sent to a bilingual teacher (English – Bengali) for translation into Bengali(Version-V1).V1 was sent to Bengali language teacher for semantic correction and idiosyncratic variants (Version -2).In collaboration with other social and psychiatric professional,V2 was compared to the final version of Bengali. The investigator one used the final scale which was filled by 32 parents/primary care giver of cleft lip and cleft palate children who were admitted to a comprehensive cleft care centre in West Bengal for their treatment. Investigator two was used the same scale in same population within 15 days of administrating the previous one. Data are tabulated and analysed and statistical method was used to calculate the content validity ratio, inter-observer reliability (ICC) and Cronbach’s alpha.

Results: Content Validity Ratio (CVR) was ranged from 0.8 – 1 which is within the acceptable limit. The overall intra-class correlation coefficient (ICC) measures 0.844 during assessment of inter – observer reliability and of Cronbach’s alpha was 0.771 which indicates that RIOFS has overall good validity and reliability measures.

Conclusion: RIOFS (2019) is very simple and valid scale which can be used with respect to the Bengali population as the finding support the psychometric properties of questionnaire.
