Chronic demands and responsivity to challenge.

Certain kinds of arousal in response to challenge situations reflect conditioning that makes one adaptive to task demands. A growing literature implicates chronic stress as a factor degenerating this conditioning. This study investigated the relation between objective occupational demands to which workers were classified for at least 2 years and various indicators of adaptive responsivity to challenge situations. There were consistently significant and negative relations between the occupational exposures and cardiovascular and skin temperature responsivity to the acute challenges administered in the laboratory, the corresponding speed of recovery to baseline after removal of the challenge stimulus, and peripheral catecholamine changes during a work shift.

Type A behavior pattern and escalating commitment.

Subjects (N = 98) were randomly assigned to high- and low-responsibility conditions in a commitment-escalation experiment. Global Type A behavior pattern and the underlying dimension of achievement strivings were positively related to the desire to continue the same course of action in the high prior-responsibility condition but not in the low prior-responsibility condition. These findings are discussed in terms of future research into the judgment processes of people with Type A personality and the possible role of escalating commitment in disorders experienced by people with Type A personality.

Dispositional affect and work-related stress.

Trait negative affectivity (NA) has been asserted to be a factor that spuriously inflates relationships between self-reported stressors and self-reported strain outcomes. We tested this hypothesis with conventional work stress instrument responses and physiological assessments obtained from 311 fire and police department employees. Confirmatory factor analyses indicated that NA did not measure a factor in common with measures of subjective strain. Latent-variable structural equations analyses, however, found that estimating the effects of NA on strain significantly attenuated the effects of work stressors. NA had no correlation with physiological stress outcomes. Trait positive affectivity did not attenuate relationships between work stressors and either subjective or objective stress outcomes. Implications for work stress research methodology and recommendations are discussed.

The nomological validity of the Type A personality among employed adults.

The nomological validity of the Type A behavior pattern was explored. The Structured Interview (SI) and a battery of personality trait, physical health, and strain measures were administered to an occupationally diverse sample of 568 workers. Ss were also monitored for physiological reactivity and recovery (blood pressure, heart rate, skin temperature, and electrodermal response) to the SI and a subsequent Stroop Color-Word Conflict Task. A confirmatory factor analysis demonstrated that SI scores can be factored into three distinct dimensions. There was considerable overlap in the patterns of personality traits that characterized the Type A components, but only a Hostility dimension was significantly related to physiological reactivity and recovery. The results have implications for distinguishing coronary-proneness from the more traditional Type A conceptualization.
