To test the hypothesis that the increased health risk of children sele
cted by a previously calculated and validated predictive model is asso
ciated with some maternal psychological characteristics, the universe
of 107 mothers of children selected by this model was evaluated by mea
ns of Goldberg's General Health Questionnaire (GHQ-30), Raven (Ra) and
Rorschach (Re) tests; 37.4% were cases according to GHQ-30, 80.9% wer
e < 50th percentile in Ra and 85% exhibited deviant responses in Ro te
sts. Children whose mother's IQ was < 50th percentile suffered more ep
isodes of total morbidity (Tm) and of diarrhoea (p = 0.0364). Children
whose mothers were normal in Ro had less Tm (p = 0.0364) and fewer re
spiratory symptoms (p = 0.0300) and tended to have less diarrhoea (p =
0.0690). In poor urban families in Santiago psychological maternal ch
aracteristics are associated with an increased health risk for the inf
ants. Supportive programmes should consider both biological characteri
stics of the infants and maternal psychological needs.
