Self-reported attention and mood symptoms in cocaine abusers: Relationship to neurocognitive performance

This study examined the relationship between subjective measures of inattention/hyperactivity-impulsivity and mood and objective measures of neurocognitive function in cocaine users.Ninety-four active cocaine users not seeking treatment (73 male, 21 female) were administered two self-report psychiatric measures (the ADHD Rating Scale - Fourth Edition; ARS-IV), and the Beck Depression Inventory - Second Edition; (BDI-II), and a battery of tests measuring attention, executive, psychomotor, visual and verbal learning, visuospatial, and language functions. Correlations between scores on the psychiatric measures (total and subscale) and the neurocognitive measures were examined.While scores on the BDI-II and ARS-IV were correlated with each other (p0.01), scores on both self-report measures were largely uncorrelated with neurocognitive test scores (p0.05).There was a minimal relationship between psychiatric measures that incorporate subjective assessment of cognitive function, and objective neurocognitive measures in nontreatment-seeking cocaine users, consistent with previous findings in other samples of substance users. This suggests that self-report measures may have limited utility as proxies for neurocognitive performance.
