Turkish Version, Validity and Reliability Study of Cold Intolerance Symptom Severity Questionnaire

Abstract

Objectives: The aim of this study was to determine validity and reliability of the Turkish version of Cold Intolerance Symptom Severity (CISS-T) Questionnaire. Material and Methods: The translation and back translation steps of the study were based on the Beaton guidelines. Sixty-eight patients between 18 to 65 years old with cold intolerance after amputation, replantation, multiple crush syndrome and peripheral nerve injury were included in the study. Patients completed the Disabilities of the Arm, Shoulder and Hand Questionnaire, the SF-36 Quality of Life Questionnaire and the single questions assessing the cold sensitivity and cold intolerance once and the final version of the CISS-T twice with 7 days interval. Results: The internal consistency (Cronbach α = 0.844) and test-retest reliability (r = 0.938) of CISS-T were assessed and both were found to be very good. Also, correlations between scores of CISS-T; DASH-T, SF36-T and the single questions were analyzed by the Spearman’s correlation coefficient. The CISS-T showed an excellent correlation with the single questions (rho 0.8 and 0.877), good and negative correlation with the SF-36 pain sub-parameter (rho=-0.617) and a moderate correlation with the DASH-T (rho=0.592). Conclusion: As a result, CISS-T is valid and reliable instrument to assess severity of cold intolerance. Key words: Cold Intolerance, Hand Injury, Turkish Version, Validity-Reliability
