Children's use of psychosocial care in a population-based longitudinal study: less likely for girls, children with a non-Western background and children with a high quality of life.

Knowledge on determinants of children's psychosocial care use is important to improve their access to care. This study examined the independent contributions of need and predisposing factors to psychosocial care use in 9-year-old children, guided by the Gateway Provider Model. Data of the Generation R Study, a prospective cohort of children born in Rotterdam, the Netherlands, were analysed using multivariable logistic regression (n = 4714). Need (quality of life, presence and type of emotional/behavioural problems) and predisposing factors (sex, ethnic background and maternal educational level) were measured using parent questionnaires at multiple time points between ages 1.5 and 9 years. Psychosocial care use was parent-reported at 9 years old (9.6% among children with Western background, 7.3% among children with non-Western background). Having emotional/behavioural problems at 5 and 9 years old was associated with more care use, while having a higher quality of life, being a girl and having a Moroccan/Turkish or other non-Western background were associated with less care use. Externalising and internalising problems, as well as several types of problems, at 5 and 9 years old were associated with psychosocial care use. Stratified analyses revealed that, in children with non-Western backgrounds, only a poorer psychosocial quality of life was associated with psychosocial care use. To conclude, girls with a Western background and children with a non-Western background were less likely to receive care compared to their peers. Children with parent-reported emotional/behavioural problems at 5 and 9 years old and decreased quality of life at 5 years old were more likely to receive psychosocial care use at 9 years old. Our findings hold relevance for preventive policies.
