Safety climate as a mediator between foundation climates and occupational accidents: a group-level investigation.

Building on recent work in occupational safety and climate, the authors examined 2 organizational foundation climates thought to be antecedents of specific safety climate and the relationships among these climates and occupational accidents. It is believed that both foundation climates (i.e., management-employee relations and organizational support) will predict safety climate, which will in turn mediate the relationship between occupational accidents and these 2 distal foundation climates. Using a sample of 9,429 transportation workers in 253 work groups, the authors tested the proposed relationships at the group level. Results supported all hypotheses. Overall it appears that different climates have direct and indirect effects on occupational accidents.

A multilevel examination of the relationships among training outcomes, mediating regulatory processes, and adaptive performance.

This study examined whether cognitive, affective-motivational, and behavioral training outcomes relate to posttraining regulatory processes and adaptive performance similarly at the individual and team levels of analysis. Longitudinal data were collected from 156 individuals composing 78 teams who were trained on and then performed a simulated flight task. Results showed that posttraining regulation processes related similarly to adaptive performance across levels. Also, regulation processes fully mediated the influences of self- and collective efficacy beliefs on individual and team adaptive performance. Finally, knowledge and skill more strongly and directly related to adaptive performance at the individual than the team level of analysis. Implications to theory and practice, limitations, and future directions are discussed.

A confirmatory approach to the factor structure of the Boredom Proneness Scale: evidence for a two-factor short form.

We analyzed previous exploratory factor analytic structures on the Boredom Proneness Scale (BPS; Farmer & Sundberg, 1986) using confirmatory factor analysis in structural equation modeling in LISREL 8 (Jöreskog & Sörbom, 1993). These analyses indicated that 2 factors were generally consistent across 6 exploratory models. Items that had significant loadings on these two factors (N = 12; 6 for each factor) indicated a lack of Internal Stimulation and External Stimulation. In further analysis on these 12 items using LISREL, we found a much improved fit and provided support for a short form version of the original BPS. We also found the shortened version to be invariant across gender. We discuss implications for the more precise measurement of boredom proneness and the use of the scale in applied settings.

Workplace safety performance: conscientiousness, cognitive failure, and their interaction.

This research investigated the effects of cognitive failure on workplace safety and accidents over 2 studies. It was hypothesized that cognitive failure would directly predict safety behavior and workplace accidents and predict these outcomes over and above conscientiousness. It was found that cognitive failure uniquely accounted for workplace safety behavior and accidents. However, it has been suggested by researchers that certain individual differences might interact to produce differential effects. Thus, a moderated model was tested examining the interaction of cognitive failure and conscientiousness. It was found that cognitive failure moderated the relationship between conscientiousness and accidents and unsafe work behaviors. Overall, results suggest that cognitive failure plays an important part in individual safety behavior, especially when conscientiousness is low.

Boredom proneness and sleep disorders as predictors of adult attention deficit scores.

This study examined the extent to which boredom proneness and sleep disturbances were related to attention deficit scores in college-aged adults. In a sample of 148 college students, Attention scores on the Adult Behavior Checklist were best predicted by Boredom Proneness (BP) subscale scores, which assess one's inability to maintain internal stimulation and feelings of constraint, and scores on the Epworth Daytime Sleepiness Scale and Athens Insomnia Scale (R2 = .57). Hyperactivity scores were best predicted by the BP subscales, which assess one's need for a stimulating environment, the perception of time passing slowly, and feelings of constraint, and the Epworth Scale (R2 = .51). The findings contribute to the understanding of the symptomatology of attention deficit in adults and provide further evidence of the validity of this measure.

The cognitive failures questionnaire revisited: dimensions and correlates.

The authors reexamined the factor structure of the Cognitive Failures Questionnaire (D. E. Broadbent, P. F. Cooper, P. Fitzgerald, & K. R. Parkes, 1982) and its correlates. The Cognitive Failures Questionnaire was designed to assess a person's likelihood of committing an error in the completion of an everyday task. A principal components factor analysis with varimax rotation yielded 4 internally consistent, interpretable factors. These factors were labeled Memory, Distractibility, Blunders, and (memory for) Names. This study lends partial support for the factor analytic solution proposed by L. K. Pollina, A. L. Greene, R. H. Tunick, and J. M. Puckett (1992). In addition, it extends previous findings by providing initial evidence for the construct validity of the factors established by correlating factor scores with measures of other related constructs (i.e., boredom proneness, attention deficit/hyperactivity disorder, Type A behavior pattern).
