The quality of home help services as perceived by the users depends on the performance of the service providers such as the handling of requests, easy-to-understand explanations and continuity of service, as well as the quality of the personal relationship between clients and helpers. The “Service Provider’s Response Scale” is a model consisting of five factors to measure the quality. However, the validity had been confirmed with data taken from only one area. Therefore, in order to investigate the cross validity, the scale was applied to other areas in the present study.
The investigation was conducted for elderly persons who used home help ser vices. An exploratory factor analysis, conducted by using the 520 responses without missing values, revealed the same factors as the hypothetical model. Though the fit index of RMSEA was poor, under the subsequent confirmatory factor analysis, the CFI and TLI indicated a good fit. Therefore, the consistency of the variance of factor structure of the scale was investigated by using multi-group analysis. Since the model, under the condition where factor loading, covariance of factors and residual variance of items were equally constrained, was acceptable in terms of the goodness of fit of the model, the cross validity of the scale was confirmed.
