Background: Cancers impose an increasing burden on health of the populations and individuals, but little isknown about cancer patient satisfaction with care. The aim of this study was to assess the psychometric propertiesof the Persian version of European Organisation for Research and Treatment of Cancer (EORTC) In-Patsat32,as a recently developed questionnaire to assess cancer patient satisfaction with care and information providedduring hospital admission. Materials and
Methods: Complying with EORTC protocols, the Persian version ofInpatsat32 was translated and piloted in a small group of patients, then applied to 380 cancer patients admittedto different oncology wards in Tehran. Validity (convergent, discriminant, and divergent) and reliability of thetool was assessed through using multitrait analysis, factor analysis, intraclass correlations, Chronbach’s alphaand test-retest (on a sample of 70 patients).
Results: Good acceptance and high sensitivity of the questionnairewith low floor and ceiling effects were recognized, indicating power of the instrument to detect differencesbetween groups with heterogeneous levels of satisfaction. Multitrait scaling analyses supported the convergentvalidity of the majority of scales (correlation coefficient >0.4) and favorable discriminant validity (item own scalecorrelation >0.8). There was no correlation between In-patsat32 scales and the EORTC-C30, which measuresdifferent concepts, confirming divergent validity of the tool. Internal consistency for all domains was high (α>0.70)except for the hospital access score and the test-retest reliability was excellent (r=0.86-0.96). There was a weakresponsiveness to change except for nurses technical skills. Principle component analysis confirmed five domainswith much improved internal consistency (α>0.9).
Conclusions: The Persian version of the EORTC-in-patsat32module is a reliable and valid instrument to measure cancer patient satisfaction with care received during theirhospitalization period and can be utilized in clinical cancer research.
