This study examined the degree to which male youth ice hockey playersʼ (N = 229, M age = 14.15 years; SD = 1.03) perfectionist orientations were associated with anger vulnerability in competition. Perfectionism and trait anger were measured as domain-specific constructs. Athletes were also asked to speculate on the likely intensity of anger responses if they were to commit mistakes in high- and low-criticality situations in competition. Canonical correlation results indicated that heightened perfectionist orientations were associated with heightened competitive trait anger. Cluster analyses produced three clusters of athletes who possessed either low, moderate, or high levels of perfectionism. Significant between-cluster differences on anger responses to mistakes were obtained, with highly perfectionistic athletes anticipating significantly higher levels of anger following mistakes than low and moderately perfectionistic athletes. A significant situation-criticality main effect was also observed, with athletes anticipating higher levels of anger following personal mistakes in high- as opposed to low-criticality situations. Results are discussed within the context of cognitive motivational theories of emotion.

In the present study we examined the demographic, medical, and social cognitive correlates of exercise intentions in non-Hodgkin’s lymphoma (NHL) survivors using the theory of planned behavior (TPB). Participants were 399 NHL survivors who completed a mailed survey that assessed demographics, past exercise, and the TPB (i.e., intention, perceived behavioral control, affective and instrumental attitudes, and subjective norm). Descriptive data indicated that only about 50% of NHL survivors intended to exercise at levels that are consistent with current public health guidelines. In support of the TPB, multiple regression analysis indicated that the model explained 55% of the variance in exercise intentions, with perceived behavioral control (β = .47), affective attitude (β = .23), and subjective norm (β = .15), being the most important correlates. It was concluded that the TPB provides a good framework on which to base interventions designed to increase exercise intentions in NHL survivors.
