Psychosocial variables associated with teenage pregnancy.

This study investigated whether psychosocial factors differentiate sexually active teenagers who become pregnant from those who do not. Data were collected from 64 unmarried adolescents who attended a suburban health clinic for a pregnancy test or for contraceptive care. Thirty-nine percent of the sample had been or were now pregnant, and 61% had never been pregnant. Each teenager completed a questionnaire and three self-report measures (Life Events Checklist, Self-Worth, Health Locus of Control) prior to her medical visit. Information about family, medical, and psychosocial history was obtained from chart review. When girls who had positive pregnancy tests, and sexually active girls who had never been pregnant were compared, no significant differences emerged on socioeconomic status, race, religion, age or psychological variables. However, when adolescents with a previous or current history of pregnancy (N = 25) were compared with girls who had never been pregnant (N = 39), using the Mann Whitney test, two significant differences were found: adolescents with a history of pregnancy had first intercourse at the mean age of 15 rather than 16 (p < .02) and scored higher than never-pregnant teenagers on the "Powerful Other" Health Locus of Control subscale, a measure of strong belief in external control by others (p < .01). No significant differences were detected between the groups for self-worth or life events perceived as stressful during the past year. These data indicate that in a middle-class suburban population of sexually active teenagers, earlier age at first intercourse and the influence of powerful others are important variables associated with pregnancy.
