Validity and reliability of Turkish adaptation of the reasons for fear of movement scale (Kinesiophopia causes scale)

ÇAYIR Melis, Reliability and Validity of the Turkish version of Kinesiophopia Causes Scale, Başkent University, Institute of Health Sciences, Department of Pyhsiotheraphy and Rehabilitation, Ankara,2018. The aim of this study is to provide the Turkish adaptation and cultural adaptation of KCS in Turkish-speaking geriatric individuals and to measure their reliability and validity. Our study included 103 healthy geriatric individuals (the average age: 71.09±4.45 years, body mass index: 27.08±4.4 kg/m2 ) the aged of 65-80 years, who had no mental problems that could interfere with cooperation and understanding and who volunteered to participate in the study. Tampa Scale of Kinesiophobia (TSK) was applied in order to determine the validity of the criterion with the KCS translated into Turkish. After 48 hours of testing for variability, which is an indicator of the reliability of the scale, KCS was applied for the second time. The internal consistency value of the questionnaire was 0.863. The Cronbach's α coefficient was 0.913 among the questions in the biological sub-dimension, and 0.797 in the psychological sub-dimension. While the biological parameters sub-dimensions (morphologic, individual need for stimulation, energetic substrates, power of biological drives) have Cronbach's α coefficient of 0.800 and above, the internal consistency of psychological parameter sub-dimensions (selfacceptance, self-assessment of motor susceptibility, body care) is respectively 0.834, 0.790, 0.642. When the correlations between TSK and KCS subscale scores were examined, there was a statistically significant positive correlation between total score of TSK and total score of KCS biological and psychological subscales (p<0.05). As a result, we think that the KCS questionnaire, which has been developed in order to determine the causes of motor inactivity and fear of movement in adults, is a valid and reliable survey in Turkish geriatric individuals and should be examined in different diseases and age groups.
