Parenting self-efficacy, maternal vigilance, competence and child behaviour were studied in a community sample of mothers of 18-36-month-old children. Thirty dysphoric mothers had elevated Beck Depression Inventory (BDI) scores (12-16) and 30 nondysphoric mothers had BDIs <5. Dysphoric mothers were more stressed, less happily married, less effective as parents and described their children as less competent and responsive than did non-dysphoric mothers. When completing a distracting questionnaim task, all mothers were less vigilant and their children less well behaved than during free play. Stressed, dysphoric mothers were observed to be less sensitive, responsive, warm, vigilant and effective in controlling their children, and their children were more destructive, and less happy, responsive and compliant. Combined maternal stress and dysphoria were associated with generally negative perceptions of self and child, and negative mother-child interactions.
