Measurement properties of a modified Reintegration to Normal Living Index in a community-dwelling adult rehabilitation population

Journal Article


Abstract


  • Purpose.To examine the validity and reliability of a modified Reintegration to Normal Living Index (mRNL Index) with a sample of community-dwelling adults with mixed diagnoses. Method.Forty-six adults (mean 55.2±20.3 years) were recruited through convenience sampling from outpatient rehabilitation services. They completed the mRNL Index, Community Integration Measure (CIM) and Life Space Assessment (LSA) and were invited to complete them again 2 weeks later. Results.Construct validity of the mRNL Index was confirmed by good fit to the Rasch measurement model. The mRNL Index demonstrated acceptable internal consistency (Cronbach's α=0.80), as did the Daily Functioning subscale (Cronbach's α=0.80) and Personal Integration subscale (Cronbach's α=0.82). Test-retest reliability was also acceptable (intraclass correlation coefficient (3,1)=0.83, p=.0001). As hypothesised, the LSA did not correlate with the Personal Integration subscale (Spearman rho=0.08) and moderately correlated to the Daily Functioning subscale (Spearman rho=0.59). The CIM was moderately correlated with the Personal Integration subscales (Spearman rho=0.54) and the Daily Functioning subscale (Spearman rho=0.53), though higher correlation was expected with the latter. Conclusion.Modifications to the phrasing, rating scale and subscales improved the validity of the original RNL Index for a mixed rehabilitation, community-dwelling population. © 2010 Informa UK, Ltd.
