On a sample of 165 adolescents (101 girls and 64 boys) we followed the relationship between the areas of achievement motivation in view of extreme values of self-efficacy and the presence of intersex differences using the Scale of General Successfulness, the Motivation Achievement Questionnaire and the Work and Family Orientation Questionnaire which differentiatedly inform about four areas of achievement motivation: (1) work - speaks of determination assiduously to work, (2) 'mastery' - of an extra measure of success in activity, (3) competition - of yearning to succeed in competitive situations, (4) avoidance of success. A characteristic trait of adolescents with high self-efficacy is a high measure of achievement motivation, they show greater determination to work assiduously, to succeed in competitive situations, have a tendency to be more successful in activities and from the aspect of their achievement, they cope better with situations involving a moderate state of tension. On the contrary, adolescents experiencing anxiety to a more intensive degree, with a negative effect on their performance, show a low level of self-efficacy. Our results point to intergender differences in the influence of the level of self-efficacy on the areas followed in these adolescents. We interpret the findings from the aspect of the effect of gender role within the socialization process.
