Validity and Reliability of a Turkish Version of the Relationship and Sexuality Scale for Kidney Transplant Recipients

Abstract

Objective: The aim of this study was to evaluate the validity and reliability of Relationship and Sexuality Scale for kidney transplant recipients in Turkey. Material and Methods: This methodological study was conducted with 150 kidney transplant recipients applied to transplant center of a university hospital between November 2016 and February 2017. “Patient Identification Form”, “Relationship and Sexuality Scale” and “The Arizona Sexual Experiences Scale” were used as data collection instruments. The data were analyzed on SPSS 23 through numbers, percentage, mean, standard deviation, content validity index, factor analysis, correlation analysis and coefficient alpha. The validity of the scale was tested using the content validity index and confirmatory and exploratory factor analyses. The process of adaptation and translation of instruments by World Health Organization was followed to provide language validity. Expert opinion was received for content validity and it was found to be coherent. The questionnaire’s factor structure demonstrated good fit, implying that it could be applied to the Turkish kidney transplant recipients population. Results: The scale consisted of three sub-dimensions according to validity testing. None of the original items were excluded. The general cronbach’s alpha coefficient of the scale was found 0.84. The principal components analysis revealed 3 factors explaining 66.40% of the variance. Correlations between item-total correlation and sub-dimensions were found positive, medium-level and statistically significant (p<0.01). Conclusion: Content validity, construct validity, and reliability analyses of the Relationship and Sexuality Scale revealed that the scale may be used to measure relationships and sexuality of kidney transplant recipients in Turkey.
