Training involving behavioral modeling, a substantial amount of practice, and dialogue is generally more effective than other methods of safety and health training. The present findings challenge the current emphasis on more passive computer-based and distance training methods within the public health workforce.

In this investigation, we report the results of 2 studies designed to (a) conduct confirmatory factor analytic tests of a model of general safety performance with performance ratings from 550 coworker appraisals (Study 1), and (b) examine hypothesized relationships between indicators of breadth and depth of knowledge constructs and confirmed safety performance factors (from Study 1) with training history data and supervisory appraisals for 133 hazardous waste workers in 23 jobs and 4 organizations (Study 2). Confirmatory factor analytic results from Study 1 provided support for a 4‐factor model of general safety performance with performance factors labeled Using Personal Protective Equipment, Engaging in Work Practices to Reduce Risk, Communicating Health and Safety Information, and Exercising Employee Rights and Responsibilities. In general, the results from Study 2 supported the hypothesized dominance of depth of knowledge over breadth of knowledge in the prediction of performance with respect to more routine, consistent safety tasks. Issues concerning the general‐izability of these factors to other types of work and the human resource management implications of these results are discussed.

The authors demonstrated that the most common statistical significance test used with r(WG)-type interrater agreement indexes in applied psychology, based on the chi-square distribution, is flawed and inaccurate. The chi-square test is shown to be extremely conservative even for modest, standard significance levels (e.g., .05). The authors present an alternative statistical significance test, based on Monte Carlo procedures, that produces the equivalent of an approximate randomization test for the null hypothesis that the actual distribution of responding is rectangular and demonstrate its superiority to the chi-square test. Finally, the authors provide tables of critical values and offer downloadable software to implement the approximate randomization test for r(WG)-type and for average deviation (AD)-type interrater agreement indexes. The implications of these results for studying a broad range of interrater agreement problems in applied psychology are discussed.

On the basis of hypotheses derived from social and experiential learning theories, we meta-analytically investigated how safety training and workplace hazards impact the development of safety knowledge and safety performance. The results were consistent with an expected interaction between the level of engagement of safety training and hazardous event/exposure severity in the promotion of safety knowledge and performance. For safety knowledge and safety performance, highly engaging training was considerably more effective than less engaging training when hazardous event/exposure severity was high, whereas highly and less engaging training had comparable levels of effectiveness when hazardous event/exposure severity was low. Implications of these findings for theory testing and incorporating information on objective risk into workplace safety research and practice are discussed.
