Birth order, self-concept, and participation in dangerous sports

We examined the effect of birth order on participation in dangerous sports, using data from a mail survey of 841 members of the United States Parachute Association drawn from the membership list of over 18,000; 52% (N = 436) responded. The questionnaires included detailed information on participation in leisure activities, background characteristics, reasons for parachuting, and self-concept; answers were obtained from an overwhelmingly middle-class, White, male, young, and college educated sample. The findings (based on descriptive statistics, correlations, and regression analysis) did not support our expectations regarding birth order and participation in dangerous sports. Several were even in opposite direction to our expectations. We did find some support for our expectation that self-efficacy would be positively related to participation in dangerous sports, but not for our expectation that self-efficacy would be related to birth order. We concluded that birth order continues to be a frustrating variable in studies of socialization.
