Reproductive decisions of parents of children with metabolic disorders.
The Interaction Model of Client Health Behavior (IMCHB) served as a guide for variable selection and instrument development for telephone interviews with 230 parents of children with metabolic disorders. Sociodemographic, psycho-affective and client-professional interaction variables were examined in relation to three outcomes: (1) receptivity to future prenatal diagnosis (56% were receptive); (2) likelihood of terminating an affected pregnancy (10% would); and (3) whether or not the parent had taken measures to prevent another affected pregnancy (41% had). All three outcomes were significantly correlated with higher scores on the Parent Stress Index, lower scores on the Vineland Adaptive Behavior Scales, fewer persons in the parent's social support network, greater worry about the living child's future and greater perceived difficulty meeting the child's extra care needs. A regression model constructed to explain taking measures to prevent a future affected pregnancy illustrated the usefulness of the IMCHB in research that involves multiple interacting variables on health outcomes. Few of the parents (7.4%) reported an interaction with a genetic counsellor, highlighting the need for practitioners from multiple disciplines to be adequately educated in principles of genetics, especially the psychological and affective aspects of counselling.
