| Abstract: | Three models are proposed to explain the relationship between individual differences in beliefs and stress responses in control-limited environments: (1) the Environmental Incongruency, (2) Differential Stress Responses, and (3) Undifferentiated Responses. The present research examined the support for each model using inmates differing in control beliefs and prison as the control-limited environment. The results did not support either the Incongruency or the Differential models. In contrast with previous studies of control-limited environments, there was no evidence of change in passive stress responses over time in prison, but there was an increase in active responses (e.g., conflicts with other inmates) early during incarceration. As predicted by the Undifferentiated Response M odel, inmates who were more external in Locus of Control experienced significantly more active and passive stress reactions. No differences were found in stress as a function of their internal beliefs. |
