Temperament,classmate likability,and social perspective coordination as correlates of children's parent-rated type A behaviors

Parents of 58 boys and 62 girls from grades three through eight completed the Matthews Youth Test for Health (MYTH), a measure of Type A behavior. Normative and reliability data were similar to those obtained from teachers as reported in the literature, but a factor analysis of parents' ratings revealed four factors (Competitiveness, Irritability, Impatience, and Leadership) as opposed to the two factors (Impatience/Aggression and Competitiveness) that have been derived from teacher ratings. Boys had higher total MYTH scores than girls, but correlations with age were not significant. No grade or gender effects were obtained for any of the four MYTH factor scores. Correlates of the MYTH scores were computed separately for boys and for girls. For boys, Irritability was related to Reactivity, a Difficult Temperament, low classmate Likeability, and poor performance on two social cognitive tasks (compromising and friendship understanding). For girls, Leadership was related to Classmate Likeability and good performance on the two social cognitive tasks. For boys only, total MYTH scores were related to low Attention Span, high Reactivity, a Difficult Temperament, and low Friendship Understanding scores. Findings are related to the gender differences found in the study of both ego control and cooperation/ competition.
