[en] Objective: Use of generic versus specific tools in psychological assessment is a controversial issue. Generic instruments can be used to measure QOL for numerous chronic illnesses; however, they may not be sensitive to particular aspects of the disease. Unfortunately, disease-specific measures cannot be used to compare results across diseases or conditions. The QLSI-C is an assessment tool that uses a modular approach developed to overcome these shortcomings. QLSI-C was devised as a generic scale to be integrated with disease specific modules. The purpose of this study is to report on reliability and validity of the QLSI-C generic scale and the cystic fibrosis (CF)-specific module.
Methods: QLSI-C was administered to 20 children with CF and 20 healthy children (ages 8-12 years) in Belgium. Internal consistency was assessed using Cronbach’s coefficient. Validity of the QLSI-C was measured using the known-groups method, i.e., analysis of variance (ANOVA) to distinguish between healthy children and children with CF. To examine the validity of the QLSI-C, correlations were calculated between the generic scale and CF-specific module.
Results: Internal consistency for the QLSI-C generic scale with the CF-specific module was good ( =.82). ANOVA results revealed a significant difference between CF and healthy children for the QOL score (p=.005), with higher average scores (i.e., lower QoL) for CF children (M=4.35) than healthy children (M=1.25). Correlations between QoL scores on the generic scale and CF-specific module demonstrated medium effect size (r=0.47; p=.04).
Conclusions: To date, three specific modules are available for the QLSI-C: (1) cancer; (2) asthma; (3) cystic fibrosis. Originality of this tool is strengthened by use of e-Health technologies (i.e., iPad app for administering the QLSI-C). Satisfactory psychometric properties and state-of-the-art use of technology suggests that the QLSI-C has potential utility for use in clinical trials, research, and clinical practice.
