Cross-Cultural Adaptation, Reliability, and Validity of the Turkish Sensory Responsiveness Questionnaire

Abstract

Abstract Importance: Sensory processing difficulties are commonly seen in people with mental disorders. However, no questionnaires specific to Turkish culture are available for people with mental disorders. Objective: To examine the cultural adaptation, reliability, and validity of the Turkish Sensory Responsiveness Questionnaire (SRQ). Design: Causal comparative groups design. Setting: Homes, clinics, hospitals, and therapy practices in Turkey. Participants: A total of 913 participants, of whom 529 were participants ages 18–60 yr with mental disorders. Outcomes and Measures: The cross-cultural adaptation and translation procedures were conducted following Beaton’s guidelines. Internal consistency was examined with Cronbach’s α. Criterion-related validity of the SRQ was determined with the Adolescent/Adult Sensory Profile using construct validity and was examined by confirmatory factor analysis (CFA) using IBM SPSS Statistics (Version 23) and AMOS (Version 24.0). Results: In CFA, model fit indices showed an acceptable fit. Test–retest reliability was excellent for the hedonic and avoidance subfactor scores and for the total score (intraclass correlation coefficients = .973, .988, and .974, respectively). Internal consistency was high for the hedonic subfactor (.812) and the avoidance subfactor (.815). Participants with bipolar disorder had the highest scores on the hedonic subfactor, whereas those with schizophrenia had the highest scores on the avoidance subfactor. Conclusions and Relevance: The 36-item SRQ is reliable and valid for analyzing the sensory processing abilities of adults in the Turkish population. Plain-Language Summary: People with mental disorders commonly have difficulties with sensory processing. No sensory responsiveness questionnaire specific to the Turkish population or culture is available for people with mental disorders. This study shows that the current form of the Turkish Sensory Responsiveness Questionnaire can contribute to understanding the sensory processing abilities of Turkish people with and without mental disorders.
