The development and validation of a generic non-managerial performance measure

[摘要] ENGLISH ABSTRACT: The human resource function attempts to proactively and reactively affect the work performance of employees through advice, diagnosis and interventions in a manner that will benefit the quality of the product and service an organisation provides to the market. In this study a generic performance construct (that can be applied to non-managerial, individual positions), was defined based on previous studies in the area of generic performance. A South African performance measure was designed accordingly that can be used to obtain multi-rater assessments of the generic, non-managerial, individual performance construct. This questionnaire was validated by evaluating the fit of the measurement model, using confirmatory factor analysis.Most of the data for this study was obtained from OK Furniture. A few questionnaires were completed by a non-probability sample of non-managerial personnel from a variety of organisations. The total sample size comprised of 205 respondents. Item and dimensionality analysis was performed on the 12 subscales to assess the success with which they represented the underlying performance constructs. In the item analysis two items were identified as somewhat problematic but both were judged not to be sufficiently problematic to delete them from the GPQ. Results from the dimensionality analysis showed satisfactory evidence that the items of each subscale reflect a common underlying factor. A spectrum of goodness-of-fit statistics was used to assess the measurement model fit. The hypothesis of exact fit was rejected but the hypothesis of close fit could not be rejected (p>.05). The position that the measurement model fits the data closely in the population was found to be a tenable position. The fit indices reflected good model fit in the sample. The measurement model parameter estimates indicated that the indicator variables represented the latent performance dimensions satisfactorily. Discriminant validity was investigated. Mixed evidence on discriminant validity was obtained. The sample size of this study was satisfactory when viewed from the perspective of statistical power given the method of item parcelling that was used, but a larger and more representative sample would have been preferable in that it would have allowed the GPQ measurement model to be fitted with individual items as indicator variables. Another limitation seemed to have been the language of the questionnaire. Informal feedback suggested that some respondents, especially those that are not fluent in English, struggled to fully understand all the questions.Recommendations for future research are made.
