City of Hope Quality of Life-Ostomy Questionnaire Validity and Reliability Assessment on a Croatian Sample

Abstract

The aim of this study was to validate City of Hope Quality of Life-Ostomy Questionnaire (CoH-QoL-OQ) for assessing the quality of life (QoL) of ostomy patients in the Republic of Croatia. The CoH-QoL-OQ is widely used, but has not been translated or validated so it can be used in the Republic of Croatia. This cross-sectional study encompassed 302 surgery patients with colostomy, ileostomy, or urostomy (182 (60.3%) male and 120 (39.7%) female), whose average age is 59 (M = 59.3, SD = 15.8). The CoH-QoL-OQ was translated into Croatian language using accepted guidelines for translation. Patients were recruited in a telephone conversation, followed by mail containing the CoH-QoL–OQ delivered to the home addresses of the patients who agreed to participate. The collected data were analyzed to verify psychometric properties of the questionnaire on the Croatian sample. All subscales showed high level of internal consistency (Cronbach α = 0.73–0.89). The test-retest reliability indicated a very satisfactory temporal stability (r = 0.99). The Confirmatory Factor Analysis (CFA), showed that the originally established model was not adequate for the data (χ2 = 4237.88, p < 0.01, CFI = 0.540, NNFI = 0.481, RMSEA = 0.113). However, after modification that excluded problematic items, the data showed a better fit with the theoretical model (except for the LR chi-square test that remained statistically significant: χ2 = 1144.28, p < 0.01, CFI = 0.869, NNFI = 0.855 RMSEA = 0.077). We conclude that the CoH-QoL-OQ is a valid, reliable, and reducible instrument for measuring the health-related quality of life (HRQoL) among Croatian patients with ostomy in clinical research and clinical practice.

Effects of the Quality of Life on the Adaptation of People With An Intestinal Stoma

“…About this, a Persian study has shown that the QOL was 6.37 (±1.66). A divergent result was observed in the present study in which physical well-being was the highest, and then the spiritual, psychological, and social dimensions (Konjevoda et al, 2020).…”

Moderating Effect of Posttraumatic Growth on the Relationship Between Social Support and Quality of Life in Colorectal Cancer Patients With Ostomies

“…4 Numerous studies have reported that all domains of quality of life were significantly influenced by ostomy-related problems, with social well-being being the most strongly affected domain. 28 , 32 , 33 Our finding indicating that social well-being was the most problematic area of quality of life is consistent with previous studies conducted in Iranian, 32 Chinese, 33 Croatian, 28 and even Korean 34 CRC patients with ostomies. Similar to a 2020 study by Konjevoda and colleagues, 28 our results highlighted poorer outcomes for patients’ psychological and social well-being compared with their physical and spiritual well-being.…”

“…Quality of life was assessed using the City of Hope Quality of Life–Ostomy that has been widely used in clinical studies with high reliability and validity. 27 , 28 This instrument consists of three sections. The first part contains 13 questions used to assess demographic, disease, and ostomy-specific characteristics.…”

Factors Associated With Quality of Life Among People Living With a Stoma in Nonmetropolitan Areas

“…First, our study sample was considerably older than those in other studies of stoma-related QoL ( Anaraki et al, 2012 ; Cotrim & Pereira, 2008 ; Dhamnaskar et al, 2019 ; Konjevoda et al, 2020 ; Liao & Qin, 2014 ; Yilmaz et al, 2017 ), and our modeling showed that older age was independently associated with better QoL. The older median age of our sample likely reflects the demographic characteristics of the study setting, as there is a higher proportion of people aged 65 years and older living in inner and outer regional areas of Australia ( AIHW, 2019 ).…”
