Purpose: To investigate the prevalence and correlates of psychopatholo
gy, as measured by the Youth Self-Report Scale, in pregnant adolescent
s so that interventions during pregnancy may be tailored to treat the
psychopathology and thereby improve maternal and child outcomes. Metho
ds: Scores on seven psychologic syndromes (withdrawn, delinquent, aggr
essive behaviors; anxiety/depression; and social, thought, and attenti
on problems) were compared for groups of pregnant adolescents (n = 185
), never pregnant teenagers (n = 126), and previously published normat
ive samples of clinically referred (n = 518) and nonreferred (n = 518)
female adolescents using chi-square, Student's t-tests, analysis of c
ovariance, or multiple logistic regression. Correlates of psychopathol
ogy were identified for the pregnant sample using odds ratios and 95%
confidence limits. Results: Pregnant adolescents exhibited less seriou
s or lower rates of psychopathology than groups against which they wer
e compared. Correlates of psychopathology included substance use durin
g pregnancy, prior assault, maternal childbirth before age 18 years, e
thnicity, greater than or equal to 3 sexual partners, and absence of a
relationship with the baby's father. Conclusions: Although the preval
ence of psychopathology was lower among pregnant patients, those who e
xhibit psychopathology are likely to engage in risky health behaviors
that contribute to poor perinatal outcome.
