Psychometric properties of the Community Integration Questionnaire - Revised (CIQ-R) in an Italian population with spinal cord injury

Study design Psychometric study. Objectives The aim of this study was to evaluate the internal consistency and validity of the Community Integration Questionnaire - Revised (CIQ-R) in Italian individuals with spinal cord injury (SCI). Setting Patients' associations, foundations, sport clubs, and federations in Italy. Methods The psychometric properties were evaluated following international guidelines. Internal consistency was assessed using Cronbach's alpha (alpha) coefficient, and test-retest reliability was assessed using intraclass correlation coefficient (ICC); concurrent validity was assessed through Pearson's Correlation Coefficient with the Short Form-12 health survey (SF-12). Results The test was administered to 80 people with SCI. Cronbach's alpha showed a value of 0.825 for the Home Integration subscale, while the other subscales and the total showed values <0.70. 30 of the 80 recruited individuals were submitted to test-retest, which showed ICC values ranging from 0.94 to 1. CIQ-R also showed a correlation between Physical Component Summary (PCS12) of the SF-12, and between Social Integration subscale's score and PCS12 and Mental Component Summary (MCS12). Correlations are also shown between Productivity subscale and PCS12 and MCS12, as well as between the total score and PCS12 and MCS12. Conclusion This study provided Italian clinicians and researchers with the first international outcome measure for measuring community integration. The validation of this measurement tool for people with SCI allows to compare outcomes of various studies. It is useful for testing the effectiveness of a treatment in various diseases and define which treatment is more effective than others.
