Standardizing outcome data in program evaluation.

D M Dush

    Community Mental Health Journal
    |January 1, 1985

    Summary

    Standardizing outcomes in service delivery evaluations allows for consistent measurement of client gains. This method uses a standard metric to compare changes across different services and data scales.

    Area of Science:

    • Health Services Research
    • Biostatistics
    • Psychometrics

    Background:

    • Evaluating service delivery systems often faces challenges due to diverse outcome measures and inherent data variability.
    • Comparing client gains across different services requires a common, interpretable metric to account for variations in measurement scales and device variability.

    Purpose of the Study:

    • To describe procedures for standardizing outcomes in service delivery system evaluations.
    • To enable the expression of client gains in a standard metric of change, irrespective of original data scales and variability.
    • To facilitate the application of common statistical analyses for understanding outcome variability.

    Main Methods:

    • Procedures for standardizing outcome data were developed.
    • Client gains were expressed using a standard metric of change, accounting for device variability.
    • Statistical analyses were applied using standardized client gains as the unit of analysis.

    Main Results:

    • Standardized gains provide a common meaning of change across different raw data scales and variability.
    • The approach allows for powerful delineation of influences on outcome variability.
    • Individual client gains, when standardized, serve as effective units for statistical analysis.

    Conclusions:

    • Standardization of outcomes is crucial for robust evaluation of service delivery systems.
    • The proposed metric enhances comparability of client gains across diverse services.
    • This methodology supports advanced statistical analysis to identify factors influencing service outcomes.
