Neuropsychological profiles of adolescents sentenced to detention in Western Australia with and without prenatal alcohol exposure

Abstract

Background/Aims

Youth with prenatal alcohol exposure (PAE) are under-recognised in the justice system, warranting improved identification. This study aimed to compare neuropsychological profiles of adolescents, with and without PAE and identify neuropsychological tasks predictive of PAE-group membership. It was hypothesised that participants with PAE would score significantly lower on neuropsychological tests.

Methods

Participants included 85 young people sentenced to detention (mean 15.7 years, 78 males), 46 with PAE. A one-way-multivariate analysis of variance tested differences in neuropsychological functioning between PAE/No-PAE groups, while logistic regression determined tests predictive of PAE.

Results

No statistically significant difference in test scores emerged between groups, and regression was not indicative of any models predictive of PAE-group membership. Neuropsychological profiles were characterised by both strengths and weaknesses, with lower verbal and mathematical skills.

Conclusion(s)

While no statistically significant differences were found between the groups, the results provided a unique insight into the neurocognitive profile of Australian youth in detention. Routine screening assessments were recommended for young people sentenced to detention.
