The intensive care unit psychosocial care scale: validity and reliability study in cardiac surgery patients

Abstract

This study aimed to test the validity and reliability of the ICU Psychosocial Care Scale in Turkish, which was developed to measure the psychosocial care of cardiac critical patients. This study was a methodological design. The study sample consisted of 180 critically ill cardiac patients meeting the inclusion criteria. The study used the ICU-Psychosocial Care (ICU-PC) Scale and The Intensive Care Experiences Scale for data collection. Data were analyzed using SPSS 22.0 and AMOS V 24.0 statistical package programs. Content validity, construct validity, reliability and concurrent validity tests were performed. The sample (n = 180) was predominantly male (66.1%) with a mean age of 65.96 ± 15.46 years. Confirmatory factor analysis was applied to confirm the 3-dimensional and 14-item structure of the scale. The fit indices of the scale were found to be χ2 = 89.24, df = 52, χ2/df = 1.716, goodness of fit index = 0.94, comparative fit index = 0.97, incremental fit index = 0.97, Tucker-Lewis index = 0.95, root mean square error of approximation = 0.05, standardized root mean square residual = 0.05. Cronbach’s alpha coefficient of ICU-PC scale was 0.87. The ICU-PC scale is a valid, reliable and distinctive scale in assessing the psychosocial care of critically ill cardiac patients.
