Potency in groups: articulating a construct.

This paper examines potency, defined as the collective belief in a group that it can be effective, and its role in determining group effectiveness. The paper illustrates the construct and reviews its origins. The distinctiveness of potency from efficacy and from other collective and motivational constructs is described. The measurement of potency is also examined. The paper concludes with a presentation of a conceptual framework for understanding the determinants of potency and with a discussion of future theory, research and practice.

Evaluating evaluation: assessment of the American Board of Internal Medicine Resident Evaluation Form.

The American Board of Internal Medicine suggests use of a standard form to rate residents on nine dimensions (such as clinical judgment and overall clinical competence) on a scale of 1 to 9. The authors examined the psychometric evidence for reliability and validity of 1,039 ratings of 85 residents by 135 attendings in a single internal medicine residency program. Of these ratings, 95.6% were from 6 to 9. Factor analysis revealed that high correlations among the nine dimensions (r ranged from 0.72 to 0.92) resulted from a single global factor accounting for 86% of the variance. The study also examined whether the form reliably distinguishes among residents scoring between 6 and 9. Agreement among attendings rating the same individual was weak (average reliability = 0.64, by the method of James). The rating method fails to discriminate dimensions of clinical care and has low reliability for distinguishing among competent residents.
