Perceived susceptibility to heart disease and preventive health behavior among Type A and Type B individuals

Although the Type A behavior pattern has been the subject of extensive research, surprisingly little information is available about the preventive health behavior of this population. Measures of perceived susceptibility, preventive health behavior, current stress, and risk for cardiovascular disease were obtained from 37 Type A and 37 Type B college students. Results indicated that the Type A students generated susceptibility judgments that covaried significantly with perceived stress. Susceptibility judgments for the Type B group, however, covaried significantly with nonbehavioral cardiovascular risk-factor status. Correlations between perceived susceptibility and preventive health behavior also differed between the two groups. For the Type A group, increments in perceived susceptibility were associated with decrements in preventive behavior. For the Type B group, however, increments in perceived susceptibility were associated with increments in preventive behavior. Between-group comparisons of preventive health behavior indicated that Type A participants were less likely to use relaxation and avoidance of overwork but were more likely than those who were Type B to regulate their diets.
