No differences were found in overall stress orsources of stress between the two groups. For pregnant adolescents, esteem was a significant predictor of overall stress, stress from deviant behaviors, and stress from "general distress." Frequent use of coping strategies and age also were significant predictors of stressfrom autonomyfor pregnant adolescents. For parenting adolescents, satisfaction with social support was the sole predictor of overall stress and stress stemmingfrom autonomy.
