Meta-Analysis of Intellectual and Neuropsychological Test Performance in Attention-Deficit/Hyperactivity Disorder.

Cognitive measures are used frequently in the assessment and diagnosis of attention-deficit/hyperactivity disorder (ADHD). In this meta-analytic review, the authors sought to examine the magnitude of differences between ADHD and healthy participants on several commonly used intellectual and neuropsychological measures. Effect sizes for overall intellectual ability (Full Scale IQ; FSIQ) were significantly different between ADHD and healthy participants (weighted d = .61). Effect sizes for FSIQ were significantly smaller than those for spelling and arithmetic achievement tests and marginally significantly smaller than those for continuous performance tests but were comparable to effect sizes for all other measures. These findings indicate that overall cognitive ability is significantly lower among persons with ADHD and that FSIQ may show as large a difference between ADHD and control participants as most other measures.

Alcohol use disorders and cognitive abilities in young adulthood: A prospective study.

The effect of alcohol use disorder (AUD) on cognitive and neuropsychological abilities was investigated in a prospective study of 68 freshmen who met past-year criteria for AUD on 2 or more occasions during their college years and 66 matched controls. At baseline, participants were administered a total of 14 subtests from the Wechsler Adult Intelligence Scale--Revised, Wechsler Memory Scale, and Halstead-Reitan Neuropsychological Battery. At 7-year follow-up, most measures were readministered, along with the Reflective Judgment Interview, Watson-Glaser Critical Thinking Appraisal, and Plant Test. Analyses revealed few differenced between AUD and control groups. However, visuospatial deficits may be present among AUD participants with poor baseline visuospatial performance. Alcohol exposure measures yielded similar patterns to those shown with AUD. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Relationship Between Neuropsychological Measures and Employment Problems in Outpatients With Substance Abuse.

Objective: To determine the relation between standard clinical neuropsychological tests and employment problems in persons with substance abuse. Participants: Sixty-four patients enrolled in an intensive outpatient substance abuse treatment program. Measures: Employment Problem Severity Score (EPSS) of the Addiction Severity Index and a comprehensive neuropsychological evaluation, including standard measures of attention, executive function, and memory. Results: Multiple regression analyses showed that response latency on the Vigilance trial of the Gordon Diagnostic System and scores on list acquisition and long-delay free recall of the California Verbal Learning Test were significant predictors of EPSS. Performance on measures of executive function did not predict EPSS. Conclusions: Neuropsychological tests may help to identify individuals at risk for employment problems, thereby improving outcomes for patients with substance abuse problems and cognitive deficits.

Neuropsychological Executive Functioning in Children at Elevated Risk for Alcoholism: Findings in Early Adolescence.

One component of individual risk for alcoholism may involve cognitive vulnerabilities prodromal to alcoholism onset. This prospective study of 198 boys followed between 3 and 14 years of age evaluated neurocognitive functioning across three groups who varied in familial risk for future alcoholism. Measures of intelligence, reward-response, and a battery of neuropsychological executive and cognitive inhibitory measures were used. Executive functioning weaknesses were greater in families with alcoholism but no antisocial comorbidity. IQ and reward-response weaknesses were associated with familial antisocial alcoholism. Executive function effects were clearest for response inhibition, response speed, and symbol-digit modalities. Results suggest that executive deficits are not part of the highest risk, antisocial pathway to alcoholism but that some executive function weaknesses may contribute to a secondary risk pathway.

"The relation of the Halstead-Reitan Neuropsychological Battery to ratings of everyday functioning in a geriatric sample"

Reports an error in "The relation of the Halstead-Reitan Neuropsychological Battery to ratings of everyday functioning in a geriatric sample" by H. Russell Searight, Edwin J. Dunn, Thomas Grisso, Ronald B. Margolis and et al (Neuropsychology, 1989, Vol 3[3], 135-145). This article presented different data analyses obtained from the sample also described in "The Relation of the Halstead- Reitan Neuropsychological Battery to Functional Daily Living Skills in Geriatric Patients" by Edwin J. Dunn, H. Russell Searight, Thomas Grisso, Ronald B. Margolis, and Judith L. Gibbons (Archives of Clinical Neuropsychology, 1990, Vol. 5, No. 2, pp. 103-117). The two papers described distinct approaches to competence assessment, using the sample. The 1990 paper described the Community Competence Scale, a test administered directly to the patient to assess daily living abilities, while the 1989 paper described data from the Scale of Competence in Independent Living Skills, an interview rating scale administered to a third party knowledgeable about the patient's living abilities. The 1990 paper was both submitted and published prior to the 1989 paper. Cross-references between the papers and footnotes about being based on the same sample were previously omitted. (The following abstract of the original article appeared in record 1991-15914-001.) Examined the relation between neuropsychological functioning, measured by the Halstead-Reitan Neuropsychological Test Battery, and daily living ability, assessed by the Scale of Competence in Independent Living Skills (SCILS) completed by a significant other. Ss were 40 geriatric patients (mean age 69.6 yrs) referred for suspected dementia. Results suggest that neuropsychological tests were moderately predictive of daily living skills. Four of the neuropsychological subtests (Speech Sounds Perception, Seashore Rhythm, Tactual Performance—Memory, and Finger Tapping—Dominant Hand) were found to be most strongly associated with daily living skills. Data suggest that although a global relation between the 2 domains exists, predictions about specific daily living skills may be unwarranted. The limitations of significant others' ratings of patients' functioning and of the SCILS are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Neuropsychological decline in frontotemporal lobar degeneration: A longitudinal analysis.

Few studies have assessed whether the patterns of neuropsychological impairment in patients with different frontotemporal lobar degeneration (FTLD) subtypes remain distinct over the duration of their illness or devolve into a common, undifferentiated neuropsychological state. A longitudinal neuropsychological analysis was obtained over 100 months assessing executive control, language/naming, and visuoconstruction in 441 patients diagnosed with Alzheimer’s disease (AD) and four FTLD subtypes, i.e., a social comportment/dysexecutive (SOC/EXEC) disorder; progressive non-fluent aphasia (PNFA); semantic dementia (SemD); and corticobasal degeneration (CBD). Initial group differences on each measure were maintained over the duration of illness, including several double dissociations. For example, AD patients exhibited a decline in 'animal' fluency; PNFA patients had difficulty on tests of executive control, SemD maintained their impairment on tests of naming, and CBD had presented with performance on visuoconstructional tests. None of the group by neuropsychological task interactions evaluating longitudinal decline was significant, suggesting that performance does not converge onto a common subtype over time. These data indicate that distinct patterns of neuropsychological impairment are maintained longitudinally, reflecting the unique anatomic distribution of relative disease burden in AD and FTLD.

The Neurocognitive Driving Test: Applying Technology to the Assessment of Driving Ability Following Brain Injury.

Objective: To compare the Neurocognitive Driving Test (NDT) with an established driving assessment method. Study Design: A prospective matched-control study. Participants: Fifteen adult volunteers with acquired brain injury (ABI), aged 21-59 years, referred for a driving evaluation and 15 healthy control (HC) participants. Methods: Individuals with ABI were administered the NDT and a traditional hospital-based driving evaluation. An overall performance score was calculated and used to rank order driving ability. HCs were administered the NDT to establish NDT performance range. Main Outcome Measures: Overall performance on the NDT; overall performance on a comprehensive hospital-based evaluation. Results: Comparison of the rank orders of driving ability for participants with ABI revealed a significant Spearman correlation. NDT scores discriminated between individuals with ABI who passed the driving evaluation and those who failed. Conclusions: Results help establish the potential utility of the NDT for evaluating driving ability in persons with ABI. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Risk Factors and Neuropsychological Recovery in Clients With Alcohol Use Disorders Who Were Exposed to Different Treatments.

Risk covariates of neuropsychological ability (NA) at treatment entry and neuropsychological recovery (NR) across 15 months were examined and replicated in 2 samples (Ns = 952 and 774) from Project MATCH, a multisite study of alcoholism treatments. NA at treatment entry was associated with age, education, and other covariates. Statistically significant mean increases in NA over time had small effect sizes, suggesting limited clinical significance of NR in the samples as a whole. However, initial NA and a combination of risk factors in direct and mediated pathways predicted a large proportion of individual differences in NR. Statistically significant but modest differential treatment effects on NR suggest that addiction treatments may need to be modified or developed to facilitate this important aspect of recovery.

Sex Differences in Visuo-Spatial Ability: Task Difficulty, Speed-Accuracy Tradeoff, and Other Performance Factors.

Males have consistently been found to perform better than females on a task that requires the subject to mentally rotate a figure. Recently, Goldstein, Haldane, and Mitchell (1990) suggested that performance factors are operative in explaining sex differences in spatial ability. However, Stumpf (1993) was unable to replicate all of Goldstein et al.'s (1990) findings and to generalize them to other measures of spatial ability. In this study, it was hypothesized (1) that females would take longer to respond and would get fewer correct items than males on a spatial rotation task, and (2) that only females would show a speed-accuracy tradeoff as the difficulty of the spatial task increased from the 90° to 180° rotated conditions. The results confirmed each of these hypotheses. Furthermore, as Stumpf (1993) found, when ratio scores from the number of items correct to number attempted were computed for both males and females, differences in spatial ability were reduced, though still evident.

"Initiating moderate to heavy alcohol use predicts changes in neuropsychological functioning for adolescent girls and boys": Correction to Squeglia et al. (2009).

Reports an error in "Initiating moderate to heavy alcohol use predicts changes in neuropsychological functioning for adolescent girls and boys" by L. M. Squeglia, et al. (Psychology of Addictive Behaviors, 2009[Dec], Vol 23[4], 715-722). The affiliation San Diego University/University of San Diego should have read San Diego State University/University of San Diego. Additionally, in the author note M. Alejandra Infante’s affiliation is listed incorrectly. Dr. Infante is affiliated only with VA San Diego Healthcare System. (The following abstract of the original article appeared in record 2009-24023-019.) This study prospectively examines the influence of alcohol on neuropsychological functioning in boys and girls characterized prior to initiating drinking (N = 76, ages 12–14). Adolescents who transitioned into heavy (n = 25; 11 girls, 14 boys) or moderate (n = 11; 2 girls, 9 boys) drinking were compared with matched controls who remained nonusers throughout the ~3-year follow-up period (N = 40; 16 girls, 24 boys). For girls, more past year drinking days predicted a greater reduction in visuospatial task performance from baseline to follow-up, above and beyond performance on equivalent measures at baseline (R2Δ = 10%, p     

The reciprocal effects of leisure time activities and intellectual functioning in older people: A longitudinal analysis.

By using data from a representative longitudinal survey, the authors provide strong evidence that complex leisure time activities increase intellectual functioning for workers and nonworkers. Ss were 315 men and 320 women aged 41–88 yrs. Although the effects were relatively moderate, both the present article and its predecessor on the effects of paid work (C. Schooler, M. Mulatu, & G. Oates, 1999) showed that, even in old age, carrying out complex tasks has a positive effect on intellectual processes. In both cases, initially high levels of intellectual functioning led to high levels of environmental complexity, which in turn raised levels of intellectual functioning, thus providing a pathway contributing to the high correlation of intellectual functioning over a 20-year period in middle and late adulthood. The present findings indicate that even in old age carrying out substantively complex tasks builds the capacity to deal with the intellectual challenges such complex environments provide.

Cognitive complaints, depression, medical symptoms, and their association with neuropsychological functioning in HIV infection: A structural equation model analysis.

The main objective of this study was to use structural equation modeling (SEM) to clarify the relationship between subjective cognitive complaints and neuropsychological functioning in 160 adults with HIV infection. Participants completed questionnaires assessing cognitive complaints, symptoms of depression, and HIV-related medical symptoms. Neuropsychological tests included measures of attention, verbal fluency, psychomotor skills, learning, memory, and executive skills. SEM was used to test models of the relationships among cognitive complaints, mood, and medical symptoms with neuropsychological functioning. The model indicated that although depressed mood (β = 0.32, p     

The heritability of cognitive functioning in very old adults: Evidence from Danish twins aged 75 years and older.

Heritable influences on cognitive functioning were investigated in a sample of 403 pairs of like-sex Danish twins aged 75 years and older. Twins completed the Mini-Mental State Examination and 3 other cognitive tests. Genetic factors accounted for 26–54% of the variance on these measures, with the balance being due to environmental factors that create differences rather than similarities among reared-together relatives. Deleting twins with severe cognitive impairment had little effect on the results, indicating that the heritability of cognitive functioning was not due entirely to genes affecting dementia. Neither age nor gender moderated twin similarity, and differential social contact could not account for correlation differences between monozygotic and dizygotic twins. These results replicate G. E. McClearn et al.'s (1997) study in indicating substantial genetic influences on late-life cognitive functioning. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Birth Weight and Cognitive Ability in Childhood: A Systematic Review.

Individual differences in cognitive ability may in part have prenatal origins. In high-risk (low birth weight/premature) babies, birth weight correlates positively with cognitive test scores in childhood, but it is unclear whether this holds for those with birth weights in the normal range. The authors systematically reviewed literature on the relationship between normal birth weight (more than 2,500 g) and childhood intelligence in term (37-42-week gestation) deliveries. Six studies met the inclusion criteria, and the authors present a comprehensive narrative review of these studies. There was a small, consistent, positive association between birth weight and childhood cognitive ability, even when corrected for confounders. Parental social class accounted for a larger proportion of the variance than birth weight, and these 2 variables were largely independent.

Semantic memory in Alzheimer's disease and the frontotemporal dementias: A longitudinal study of 236 patients.

Using semantic dementia (SD) as a reference point, the authors assessed semantic memory in four other neurodegenerative disorders: progressive nonfluent aphasia (PNFA), frontal variant frontotemporal dementia (fvFTD), Alzheimer's disease (AD), and posterior cortical atrophy (PCA). Individuals with SD were more impaired than other groups on semantic measures and showed a characteristic pattern across tasks: category fluency (CF) worse than letter fluency (LF), naming worse than comprehension, and visual and verbal comprehension equally affected, suggesting disruption to an amodal semantic system. Individuals with AD demonstrated a similar pattern to a milder degree. Although PNFA, fvFTD, and PCA groups had abnormal scores (relative to controls) on most semantic measures, their differing patterns across measures indicate that the apparent semantic impairment in these conditions is largely secondary to other factors.

Spatial Ability and Home-Range Size: Examining the Relationship in Western Men and Women (Homo sapiens).

In mammals, spatial sex differences may have coevolved with sex differences in the size of home ranges. This study first evaluated whether, in keeping with most mammals and traditional human (Homo sapiens) societies, home ranges are larger in male than in female Westerners. Second, it established whether navigation patterns are associated with a broader set of spatial abilities in men than in women. Results showed that current male home ranges surpass female home ranges. Ranging was also positively correlated with achievement in tests of mental rotation, surface development, and location memory among men only, whereas it was associated with embedded figures scores in both sexes. Overall, these findings substantiate the adaptive role of several spatial sex differences in humans. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

"The Memory Functioning Questionnaire for assessment of memory complaints in adulthood and old age": Correction to Gilewski et al.

Reports an error in "The Memory Functioning Questionnaire for assessment of memory complaints in adulthood and old age" by Michael J. Gilewski, Elizabeth M. Zelinski and K. Warner Schaie (Psychology and Aging, 1990[Dec], Vol 5[4], 482-490). In the aforementioned article, the author note at the beginning of the article should have contained the following statement: "The Memory Functioning Questionnaire (MFQ) items that appear in the appendix at the end of this article were published previously in 'Memory Functioning Questionnaire (MFQ)' by Michael J. Gilewski and Elizabeth M. Zelinski (Psychopharmacology Bulletin, 1988, Vol. 24, No. 4, pp. 665-670). The current article reflects the construction validation, scoring, and interpretation of the MFQ more accurately than does the article that appeared in Psychopharmacology Bulletin." (The following abstract of the original article appeared in record 1991-08788-001.) The results of psychometric analyses of the Metamemory Questionnaire (MQ) of E. M. Zelinski et al (1980), developed to evaluate perception of everyday memory functioning, are presented for a sample of 343 men and 435 women (aged 16-89 yrs). Exploratory factor analysis yielded 4 correlated factors (General Frequency of Forgetting, Retrospective Functioning, and Mnemonics Usage) that accounted for 36.7% of the variance in responses to the MQ. Factor structure was invariant across age groups (16-54 vs 55-89 yrs), 2 independent samples, and over 3 yrs. Because some of the original MQ scales did not load on the factors, only 64 of the original 92 items were retained for inclusion in the Memory Functioning Questionnaire (MFQ). Internal consistency of MFQ scores is high. The MFQ is therefore reliable for evaluating memory self-appraisals. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Modeling Memory Decline in Older Adults: The Importance of Preclinical Dementia, Attrition, and Chronological Age.

This longitudinal study examined memory loss in a sample of 391 initially nondemented older adults. Analyses decomposed observed memory loss into decline associated with preclinical dementia, study attrition, terminal decline, and chronological age. Measuring memory as a function of only chronological age failed to provide an adequate representation of cognitive change. Disease progression accounted for virtually all of the memory loss in the 25% of the sample that developed diagnosable dementia. In the remainder of the sample, both chronological age and study attrition contributed to observed memory loss. These results suggest that much of memory loss in aging adults may be attributable to the progression of preclinical dementia and other nonnormative aging processes that are not captured by chronological age.

The Role of Change in the Relationship Between Commitment and Turnover: A Latent Growth Modeling Approach.

Through the use of affective, normative, and continuance commitment in a multivariate 2nd-order factor latent growth modeling approach, the authors observed linear negative trajectories that characterized the changes in individuals across time in both affective and normative commitment. In turn, an individual's intention to quit the organization was characterized by a positive trajectory. A significant association was also found between the change trajectories such that the steeper the decline in an individual's affective and normative commitments across time, the greater the rate of increase in that individual's intention to quit, and, further, the greater the likelihood that the person actually left the organization over the next 9 months. Findings regarding continuance commitment and its components were mixed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Personal Functioning Inventory: A reliable and valid measure of adaptiveness in coping.

This article reports the development and validation of the Personal Functioning Inventory (PFI), a new measure of adaptiveness in coping. In Study 1, two adult samples (Ns of 105 and 101) showed the PFI to be highly reliable and to correlate substantially with a summed rating scale for adaptiveness. Study 2 with 140 undergraduates again showed the PH to be highly reliable and to relate positively to problem-solving confidence and negatively to perceived stress. Study 3, a two-wave longitudinal study with a three-week intersession interval, involved 149 undergraduates at Time 1 and retained 107 at Time 2. It demonstrated strong reliability and stability for the PFI, concurrent and predictive positive relations with selfrated adaptiveness and prolonged state anxiety, and discriminant validity against abstract curiosity. Factor analyses consistently supported a one-factor structure for the PFI. Possible applications for the scale are noted. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
