Cross-cultural adaptation and psychometric properties of the greek sensory profile (Sp-Gr) caregiver questionnaire

Abstract

OBJECTIVE Cross-cultural adaptation and assessment of the psychometric properties of the Sensory Profile (SP) caregiver questionnaire in the Greek language (SP-Gr). METHOD The SP caregiver questionnaire was translated, culturally adapted and piloted according to internationally accepted guidelines. The questionnaire was translated into Greek by two bilingual translators, who then discussed and compiled the results of the two separate translations (T1 and T2) into a joint version of the questionnaire (T12). A third bilingual person translated the joint version back into English and all three collaborated to produce a semi-final version. The semi-final version was pilot tested on 30 mothers of children aged 3 to 10 years, 20 of which had children of typical development and 10 atypical development. For the test-retest reliability, 66 parents (mainly mothers of differing educational and socioeconomic background, of children aged 3–10 years, 38 of typical development and 28 of atypical development), completed the SP-Gr at two different times, spaced 7–14 days apart. For construct validity, the known-group method was utilized, exploring the differences between the two groups (typical development and atypical development) in all the SP parameters (sections, factors, and quadrants). The atypical development group consisted of children with autism spectrum disorder (ASD), specific learning disabilities, attention-deficit/ hyperactivity disorder (ADHD), and Down syndrome. RESULTS Test-retest reliability was very high for quadrant (ICC=0.91–0.95), for factor (ICC=0.78–0.94) and section scores (ICC=0.81–0.95). Internal consistency was also high for quadrants (α=0.86–0.92), and for all but two factors (α=0.80–0.91) and fairly good for the section scores (α=0.75–0.88). Differences between children of typical and atypical development were significant in almost all sections, factors and quadrants (p<0.05), demonstrating the construct validity of the questionnaire. CONCLUSIONS The SP-Gr caregiver questionnaire was found to be acceptable, understandable, valid and reliable by Greek parents and may thus be used in cross-cultural clinical practice and research. This study supports the use of quadrant scores over factor and section scores to analyze children’s sensory processing patterns. © Athens Medical Society.
