Examining the psychometric properties of the Hindi version of Family Accommodation Scale-Self-Report (FAS-SR)

摘要

Highlights ? Family accommodation is an important construct with significant bearing on the outcome and burden of OCD. ? There is paucity of resources and training facilities in developing countries like India, which makes an interviewer-rated scale costly as well as labour-intensive. ? The Hindi version of self-rated FAS-SR scale showed good inter-item correlation and significant positive correlation with FAS-IR. ? A Hindi version of the FAS-SR could provide a cost-effective and time-efficient means of assessing family accommodation. Abstract Context Family accommodation (FA) is the phenomenon whereby caregivers assist or facilitate rituals or behaviours related to obsessive compulsive disorder (OCD). There is a need for a self-rated instrument to assess this construct in resource-strained clinical settings of India. Aim To explore the factor structure of Hindi version of Family Accommodation Scale-Self Rated version (FAS-SR) and compare its validity with the gold standard Family Accommodation Scale-Interviewer Rated (FAS-IR) scale. Material & methods The Hindi version of FAS-SR scale and FAS-IR scale was applied on 105 caregivers of patients with OCD. Results The initial factor analysis yielded three-factor models with an eigenvalue of >1 and the total variance explained by these factors was 72.017%. The internal consistency of the 19-item scale was 0.93 indicating good inter-item correlation. There was a significant positive correlation between FAS-IR scale total score and all the factors of the FAS-SR Scale. The average measure ICC was 0.889 with a 95% confidence interval from 0.783 to 0.981 (F (62,84)=37.547, p Conclusions FAS-SR is a practical alternative to FAS-IR and has the potential to be used widely in an Indian setting.
