Higher Levels of Intelligence and Executive Functioning Protect Maltreated Children Against Adult Arrests: A Prospective Study.

ABSTRACT: Research shows that maltreated children are at elevated risk of arrest as adults and that higher verbal intelligence, reading ability, and executive functioning (abstract reasoning and cognitive flexibility) may be protective against criminal behavior. The current study examines this hypothesis using data from court-substantiated cases of child abuse and neglect and demographically matched controls followed prospectively into middle adulthood ( N = 1,196). At age 29, verbal intelligence was assessed with the Quick Test and reading ability with the Wide Range Achievement Test-Revised. At age 41, abstract reasoning was assessed with the Matrix Reasoning Test and cognitive flexibility with the Trail Making Test-B. Arrest records were gathered from law enforcement agencies through mean age 51. Data were analyzed with binomial logistic regressions. The results indicated that maltreated children were at increased risk of arrest for nonviolent and violent crime. Higher verbal intelligence, reading ability, nonverbal reasoning, and cognitive flexibility were protective against arrest for violent crime. The protective effects of neuropsychological functions were more pronounced for violent than nonviolent crime, for the control than maltreated children, and differed by gender and race. These results suggest that interventions targeting improved cognitive and neuropsychological functions may serve an important role in reducing risk of crime.

Project description:BackgroundExecutive functioning deficits are common in children with neurodevelopmental disorders. However, prior research mainly focused on clinical populations employing cross-sectional designs, impeding conclusions on temporal neurodevelopmental pathways. Here, we examined the prospective association of executive functioning with subsequent autism spectrum disorder (ASD) traits and attention-deficit/hyperactivity disorder (ADHD) traits.MethodsThis study included young children from the Generation R Study, a general population birth cohort. The Brief Rating Inventory of Executive Function-Preschool Version was used to assess parent-reported behavioral executive functioning when the children were 4 years old. ASD traits were assessed at age 6 (n = 3938) using the parent-reported Social Responsiveness Scale. The Teacher Report Form was used to assess ADHD traits at age 7 (n = 2749). Children with high scores were screened to determine possible clinical ASD or ADHD diagnoses. We were able to confirm an ASD diagnosis for n = 56 children by retrieving their medical records and established an ADHD diagnosis for n = 194 children using the Diagnostic Interview Schedule for Children-Young Child version (DISC-YC). Data were analyzed using hierarchical linear and logistic regressions.ResultsImpaired executive functioning was associated with more ASD and ADHD traits across informants (for ASD traits and diagnoses: β = 0.33, 95% CI [0.30-0.37]; OR = 2.69, 95% CI [1.92-3.77], respectively; for ADHD traits and diagnoses: β = 0.12, 95% CI [0.07-0.16]; OR = 2.32, 95% CI [1.89-2.85], respectively). Deficits in all subdomains were associated with higher levels of ASD traits, whereas only impaired inhibition, working memory, and planning/organization were associated with more ADHD traits.ConclusionsThe findings of the current study suggest a graded association of executive functioning difficulties along the continuum of ASD and ADHD and that problems in executive functioning may be a precursor of ASD and ADHD traits from an early age onwards.

Project description:Neurocognitive heterogeneity is increasingly recognized as a valid phenomenon in ADHD, with most estimates suggesting that executive dysfunction is present in only about 33%-50% of these children. However, recent critiques question the veracity of these estimates because our understanding of executive functioning in ADHD is based, in large part, on data from single tasks developed to detect gross neurological impairment rather than the specific executive processes hypothesized to underlie the ADHD phenotype. The current study is the first to comprehensively assess heterogeneity in all three primary executive functions in ADHD using a criterion battery that includes multiple tests per construct (working memory, inhibitory control, set shifting). Children ages 8-13 (M?=?10.37, SD?=?1.39) with and without ADHD (N?=?136; 64 girls; 62% Caucasian/Non-Hispanic) completed a counterbalanced series of executive function tests. Accounting for task unreliability, results indicated significantly improved sensitivity and specificity relative to prior estimates, with 89% of children with ADHD demonstrating objectively-defined impairment on at least one executive function (62% impaired working memory, 27% impaired inhibitory control, 38% impaired set shifting; 54% impaired on one executive function, 35% impaired on two or all three executive functions). Children with working memory deficits showed higher parent- and teacher-reported ADHD inattentive and hyperactive/impulsive symptoms (BF10?=?5.23?×?104), and were slightly younger (BF10?=?11.35) than children without working memory deficits. Children with vs. without set shifting or inhibitory control deficits did not differ on ADHD symptoms, age, gender, IQ, SES, or medication status. Taken together, these findings confirm that ADHD is characterized by neurocognitive heterogeneity, while suggesting that contemporary, cognitively-informed criteria may provide improved precision for identifying a smaller number of neuropsychologically-impaired subtypes than previously described.
