Background: Parents of children suffering from neurodevelopmental disorders, frequently face public stigma which is often internalized and leads to psychological burden. However, there is a lack of data on the perceptions of internalized stigma among parents of children with neurodevelopmental disorders, especially from lower-middle-income countries like India. Aims: This study aims to develop an adapted version of the Internalized Stigma of Mental Illness (ISMI) scale for use in parents of children suffering from neurodevelopmental disorders and to explore the factor structure of this instrument through exploratory factor analysis (EFA). Settings and Design: A cross-sectional study was conducted in an outpatient setting in a tertiary care hospital in India. Materials and Methods: A total of 105 parents of children suffering from neurodevelopmental disorders (according to the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition) were recruited for the study after screening for psychiatric disorder using Mini International Neuropsychiatric Interview version 6.0. A modified 16-item scale was constructed Parents' Internalized Stigma of Neurodevelopmental Disorder in Child (PISNC) scale and applied on 105 parents of children suffering from neurodevelopmental disorders, after translation to Hindi and back-translation, in keeping with the World Health Organization's translation-back-translation methodology. Statistical Analysis: EFA was carried out using principal component analysis with orthogonal (varimax) rotation. Internal consistency of the Hindi version of the scale was estimated in the form of Cronbach's alpha. Spearman–Brown coefficient and Guttman split-half coefficient were calculated to evaluate the split-half reliability. Results: The initial factor analysis yielded three-factor models with an eigenvalue of >1 and the total variance explained by these factors was 62.017%. The internal consistency of the 16-item scale was 0.91 indicating good inter-item correlation. Approximately 39.4% of the parents reported some form of Internalized stigma. Conclusions: The results revealed that the PISNC scale has high internal consistency and that it is made up of three distinctive factors: social withdrawal and alienation, stereotype endorsement, and discrimination experience. These factors although similar, are not identical, to the factors that underlie the ISMI scale.
