The Turkish Adaptation of Sussex Misophonia Scale and A Short Form of the Scale

Misophonia is a neuropsychiatric disorder characterized by emotions, thoughts, behaviours toward certain sensory stimuli. Sussex Misophonia Scale (SMS) is one of the scales intending to measure misophonia. In this study we aimed to conduct Turkish adaptation of SMS and present a short form of the scale. We conducted a translation and back-translation process. The scale was applied to a subgroup of the sample. In line with feedback final version was distributed via online platforms. Reliability and validity analyses were conducted. Due to multi-loading of items, 19 items from Part II were eliminated. We defined this 19-itemed form as short form of the scale and same reliability, and validity analyses were conducted with this short form. SMS was reliable scale with .97 The Cronbach's Alpha value for Part 2. However, in EFA analysis, Kaiser-Meyer-Olkin analysis was conducted, resulting in value of .954. The Bartlett’s Test of Sphericity yielded a value of χ2=8508.921and a p<.001. The short form demonstrated a Cronbach's Alpha value of .913. Both original and short form of the scale were clinically valid. The Turkish version of SMS was reliable and valid scale. We presented short form of Part II of the scale and this short form was also reliable and valid.
