Stability of measures of the home environment for families of children with severe disabilities

The stability of home environment in families of children with severe disabilities was investigated. Sixty-four families were assessed at three time points regarding aspects of their home environment. Family environment scale, home quality rating scale (HQRS) and home observation for measurement of the environment scores were collected at 7 and 9 years after the initial assessment. A remarkable degree of stability was observed, particularly for the FES. The median change score was zero for most subscales; no correlations differed significantly between the 7- and 9-year retests. A repeated measures MANOVA found a significant change in scores over time for only one subscale of the HQRS but none of the 10 FES subscales. Results suggest that, for the FES, administration of these measures every 2 years, perhaps less often, would be sufficient in longitudinal studies of this population. Internal consistency reliability of the FES was lower for these families than in the standardization samples, emphasizing the need to validate measures used with special populations.
