    This paper describes a limitation of using Cronbach's Alpha to estimate reliability when using a sample with homogeneous responses in the measured construct. More specifically, it describes the risk of falsely concluding that a new instrument may have poor reliability and demonstrates the use of an alternate statistic that may serve as a cushion against such errors. Data from two validation studies are used to illustrate the utility of the new statistic, referred to as R-Alpha or Relative Alpha. Included is a discussion of the limitations and appropriate use of the statistic in validating multi-item tests, assessment scales, and inventories.

    Data from veterans of the Persian Gulf engagement were studied to assess the potential of second-order factor analysis in examining, interpreting, and directing person-environment interventions with an array of different but related individual and environmental problems. Participants of the study were 1,532 veterans of the Persian Gulf engagement who were eligible for social services provided by the Veterans Administration. The results provided support for the use of second-order factors in examining client data and provided information about the relationships among clinically significant problems. Further research on the second-order factors of multidimensional instruments that are used in social work to measure client progress can yield information about how client populations differ and provide direction in selecting interventions that are congruent with social work's person-environment focus.
