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 (α) 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 α 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.

Crosscultural Validation of the Community Integration Questionnaire-Revised in an Italian Population.

OBJECTIVE: The aims of this study are the translation, cultural adaptation, and validation of the Community Integration Questionnaire-Revised (CIQ-R) in Italian in a group of individuals with no clinical evidence of disability. METHODS: The test's internal consistency and validity were assessed by following international guidelines. The test's internal consistency was examined using Cronbach's alpha (α) coefficient. Pearson's correlation coefficient was calculated to assess the test's concurrent validity compared with the Short Form-12 (SF-12) health survey. RESULTS: The CIQ-R was administrated to 400 people with no clinical evidence of disease, impairment, or disability, aged between 18 and 64. Cronbach's α reported a value of 0.82 in the home integration subscale. The test also showed a good test-retest reliability, with an Intraclass Correlation Coefficient of 0.78, and a significant correlation between the total score of the CIQ-R and the Physical Component Summary (PCS) of the SF-12 (r = 0.118), between the "social integration" subscale's score and PCS12 (r = 0.121) and between the "Electronic Social Networking integration" subscale's score and PCS12 (r = 0.184), with p < 0.05. CONCLUSION: This is the first study to report the results of the translation and validation of the CIQ-R in Italian. The CIQ-R is an important tool for Italian professionals and can be useful in both clinical practice and research for measuring the level of community integration among the healthy population.
