The validity of general cognitive ability predicting job-specific performance is stable across different levels of job experience.

Decades of research in industrial-organizational psychology have established that measures of general cognitive ability (g) consistently and positively predict job-specific performance to a statistically and practically significant degree across jobs. But is the validity of g stable across different levels of job experience? The present study addresses this question using historical large-scale data across 31 diverse military occupations from the Joint-Service Job Performance Measurement/Enlistment Standards Project (N = 10,088). Across all jobs, results of our meta-analysis find near-zero interactions between Armed Forces Qualification Test score (a composite of math and verbal scores) and time in service when predicting job-specific performance. This finding supports the validity of g for predicting job-specific performance even with increasing job experience and provides no evidence for diminishing validity of g. We discuss the theoretical and practical implications of these findings, along with directions for personnel selection research and practice.

Explaining the Validity of the ASVAB for Job-Relevant Multitasking Performance: The Role of Placekeeping Ability.

Scores on the Armed Services Vocational Aptitude Battery (ASVAB) predict military job (and training) performance better than any single variable so far identified. However, it remains unclear what factors explain this predictive relationship. Here, we investigated the contributions of fluid intelligence (Gf) and two executive functions-placekeeping ability and attention control-to the relationship between the Armed Forces Qualification Test (AFQT) score from the ASVAB and job-relevant multitasking performance. Psychometric network analyses revealed that Gf and placekeeping ability independently contributed to and largely explained the AFQT-multitasking performance relationship. The contribution of attention control to this relationship was negligible. However, attention control did relate positively and significantly to Gf and placekeeping ability, consistent with the hypothesis that it is a cognitive "primitive" underlying the individual differences in higher-level cognition. Finally, hierarchical regression analyses revealed stronger evidence for the incremental validity of Gf and placekeeping ability in the prediction of multitasking performance than for the incremental validity of attention control. The results shed light on factors that may underlie the predictive validity of global measures of cognitive ability and suggest how the ASVAB might be augmented to improve its predictive validity.

Exposomic Signatures of Cervical Pain.

We evaluated risk factors associated with cervical pain (CP) among officers and enlisted members of the U.S. Army and Marine Aviation community using an exposomic approach. Specifically, we aimed to determine the factors associated with reported CP. This is a retrospective cohort study that utilized the Medical Assessment and Readiness System housed at Womack Army Medical Center to evaluate the longitudinal data taken from medical and workforce resources. This study included 77,864 active duty AMAC members during October 2015-December 2019. Multivariable mixed-effects logistic regression was used to assess the relationship between the independent variables of rank, service time, deployment, Armed Forces Qualification Test score, tobacco use, alcohol use, age, gender, race, ethnicity, body mass index, marital status, and education level and the dependent variable, incidence occurrence of CP. The total analysis included 77,864 individuals with 218,180 person-years of observations. The incidence rate of CP was 18.8 per 100 person-years, with a 12% period prevalence. Cervical pain was independently associated with rank, service time, Armed Forces Qualification Test score, and alcohol use (all P < .05). Our longitudinal exposomic signatures-based approach aims to complement the outcomes of data science and analytics from Medical Assessment and Readiness System with validations of objective biochemical indicator species observed in Army and Marine Aviation community members suffering from CP. This initial approach using parallel track complementarity has the potential of substantiating the underlying mechanisms foundational to design prospective personalized algorithms that can be used as a predictive model. Finally, a specific evaluation of occupational risk factors may provide insight into factors not readily ascertained from the civilian literature.

A-236 The Role of Socio-Demographics on the Test of Memory Malingering (TOMM) Performance Using a Large Military Sample.

Abstract Objective: The current study aims to assess the relationship among scores on the test of memory malingering (TOMM) and general demographics (age, education, ethnicity, and gender) as well as military-specific variables (Armed Services Vocational Aptitude Battery (ASVAB), number of deployments, and blasts) using a large military sample. Method: An archival dataset (https://osf.io/rv9cj/), representative of the military personnel according to the Marine Corps Demographics Update (2015) consisting of 875 participants between 18-62 years, predominately male and caucasian was analyzed. Participants were referred by their medical provider for psychological and/or neurological complaints and completed a neuropsychological evaluation comprised of a clinical interview and a neuropsychological blast battery consisting of demographics and 15 tests, including the TOMM. Pre-morbid information was gathered using the ASVAB which has the following subscales: armed forces qualification test, general technical, mechanical maintenance, clerical, and electronics. Results: A decrease in TOMM Trial 2 scores was significantly associated with an increase in age r(732) = -.09, p = .014, education r(717) = -.10, p = .008, mechanical maintenance, r(330) = .12, p =.04; clerical, r(313) = .11, p =.04; and electronics r(328) = .13, p =.02. TOMM Trail 2 scores were not significantly associated with other variables. Conclusions: The findings show a weak relationship between TOMM Trial 2 and age, education, and a few subscales of ASVAB. This suggests that both demographic and vocational abilities appear to be potential mediating variables in understanding the role of effort in interpreting neuropsychological performance.

Army Service in the All-Volunteer Era

Abstract Since the beginning of the all-volunteer era, millions of young Americans have chosen to enlist in the military. These volunteers disproportionately come from disadvantaged backgrounds, and while some aspects of military service are likely to be beneficial, exposure to violence and other elements of service could worsen outcomes. This article links the universe of army applicants between 1990 and 2011 to their federal tax records and other administrative data and uses two eligibility thresholds in the Armed Forces Qualification Test (AFQT) in a regression discontinuity design to estimate the effects of army enlistment on earnings and related outcomes. In the 19 years following application, army service increases average annual earnings by over ${\$}$4,000 at both cutoffs. However, whether service increases long-run earnings varies significantly by race. Black servicemembers experience annual gains of ${\$}$5,500 to ${\$}$15,000 11–19 years after applying while white servicemembers do not experience significant changes. By providing Black servicemembers a stable and well-paying army job and by opening doors to higher-paid postservice employment, the army significantly closes the Black-white earnings gap in our sample.

Abstract P231: The Impact Of Intelligence In Youth On Cardiovascular Diseases Among 54-61 Years Old Americans

Introduction: The association between intelligence measured in youth and all cause-mortality has been previously established, where people with lower intelligence had a higher mortality risk. Few studies have looked at the relationship between intelligence and CVD morbidity. Hypothesis: We assessed the hypothesis that higher intelligence in youth is associated with lower odds of CVD adjusting for the social determinants of health. Methods: Our sample population consisted of 9,964 men and women who participated in the National Longitudinal Survey of Youth 1979 and responded to the 2018 survey (round 28). The intelligence was measured when participants were around 15 to 23 years of age using the Armed Forces Qualification Test and was scored as a percentile and z-scored. CVDs were measured as self-reports of a doctor ever diagnosing hypertension, myocardial infarction, angina, congestive heart failure, ischemic stroke, or general heart problems in 54-61 years old Americans. Crude and adjusted for age, sex, ethnicity, highest grade of education completed, and total net family income logistic regression models were used to test the association between intelligence and CVD. Results: Conclusions: In conclusion, the current findings suggest that higher intelligence may be a protective factor against CVD. Previous associations in populations younger than ours were attenuated, suggesting that the relationship may no longer exist when including older Americans. However, identifying the most vulnerable groups as priority areas for reducing CVD morbidities is key to reducing impact and promoting health equity. The data from this study can inform health and social policies, which can help reduce the burden of CVD. Public health efforts that account for variation and contribution of intelligence, as well as social determinants of health, are needed to reduce CVD and its risk factors.

Age 20 Cognitive Ability Moderates the Long-Term Influence of Lifestyle Behaviors on Brain Aging in Late Midlife

We examined whether the longitudinal association between lifestyle behaviors and brain age is moderated by early general cognitive ability (GCA). The sample comprises 356 participants from the Vietnam Era Twin Study of Aging (VETSA). At mean age 40 (SD 2.7; range 34-44) a positive lifestyle index was created comprising three self-reported behaviors: not smoking, zero to moderate alcohol consumption, and high social engagement. GCA at mean age 20 was assessed with the Armed Forces Qualification Test. At mean age 68 (SD 2.6; range 61-72), participants underwent structural magnetic resonance imaging which was used to create predicted brain age difference (PBAD) scores. Multivariate models included GCA, lifestyle and their interaction as IVs, adjusted for age, ethnicity, APOE genotype, height, and family membership. Age 20 GCA and age 40 lifestyle significantly predicted age 68 PBAD [F=5.83; p=.02 and F=15.14; p<.001, respectively]. Both positive behaviors and higher age 20 GCA were associated with less brain aging. The GCA-lifestyle interaction was also significant. Those with both lower age 20 GCA and fewer positive behaviors had older brains relative to chronological age [F=5.00; p=. 03]. When GCA was high, however, participants had younger brains, regardless of lifestyle behaviors, suggesting a protective effect of early high GCA or cognitive reserve on later brain health. However, for those with lower cognitive reserve, positive lifestyle behaviors appeared to be protective against brain aging nearly three decades later. Results highlight the important role of cognitive reserve and lifestyle factors for later life brain health.

Attrition and reenlistment in the Army: Using the Tailored Adaptive Personality Assessment System (TAPAS) to improve retention

ABSTRACTAttrition and reenlistment are critical outcomes that continually shape the Army’s workforce. However, relatively little is known about factors that reliably predict which Soldiers will ultimately complete their first term of service or reenlist after their first term has concluded. The present study evaluated the efficacy of a noncognitive measure, the Tailored Adaptive Personality Assessment System (TAPAS), as well as a traditional cognitive test, the Armed Forces Qualification Test (AFQT), as predictors of attrition and reenlistment. Specific categories of attrition were examined based on the reasons Soldiers separated from the Army, both during training and while the Soldiers were in their units. Additionally, analyses were conducted to model attrition over time, and reenlistment was examined both Army-wide and for specific MOS. The paper concludes with a discussion of the findings and needs for future research concerning the potential value of cognitive and noncognitive measures for better understanding and predicting Army attrition and reenlistment.

Parents’ Education Is More Important Than Their Wealth in Shaping Their Children’s Intelligence: Results of 19 Samples in Seven Countries at Different Developmental Levels

In 19 (sub)samples from seven countries (United States, Austria, Germany, Costa Rica, Ecuador, Vietnam, Brazil), we analyzed the impact of parental education compared with wealth on the cognitive ability of children (aged 4–22 years, total N = 15,297). The background of their families ranged from poor indigenous remote villagers to academic families in developed countries, including parents of the gifted. Children’s cognitive ability was measured with mental speed tests, Culture Fair Intelligence Test (CFT), the Raven’s, Wiener Entwicklungstest (WET), Cognitive Abilities Test (CogAT), Piagetian tasks, Armed Forces Qualification Test (AFQT), Progress in International Reading Literacy Study (PIRLS), Trends in International Mathematics and Science Study (TIMSS), and Programme for International Student Assessment (PISA). Parental wealth was estimated by asking for income, indirectly by self-assessment of relative wealth, and by evaluating assets. The mean direct effect of parental education was greater than wealth. In path analyses, parental education ( βEd) also showed a stronger impact on children’s intelligence than familial economic status ( βIn, total effect averages: βEd= .30–.45, βIn= .09–.12; N = 15,125, k = 18). The effects on mental speed were smaller than for crystallized intelligence, but still larger for parental education than familial economic status ( βEd→MS= .25, βIn→MS= .00, βEd→CI= .36, βIn→CI= .09; N = 394, k = 3). Additional factors affecting children’s cognitive ability are number of books, marital status, educational behavior of parents, and behavior of children. If added, a general background (ethnicity, migration) factor shows strong effects ( βBg= .30–.36). These findings are discussed in terms of environmental versus hidden genetic effects.

Intelligence across the seventh decade in patients with brain injuries acquired in young adulthood.

In this longitudinal study, we examined intelligence in a group of Vietnam veterans in their 60 s who suffered combat-related penetrating traumatic brain injuries (pTBI) in their 20 s (n = 120), as well as matched veterans with no brain damage (n = 33). Intelligence was evaluated using the Armed Forces Qualification Test (AFQT) administered before the injury occurred and then again at three points in time over the following 45 years. We tested for potential predictors and correlates of late midlife intelligence score, as well as the recent change in score over the seventh decade. The pTBI group had lower intelligence scores than the control group when currently evaluated. Pre-injury intelligence and the presence of a pTBI were the most consistent predictors of current intelligence scores. While exacerbated intellectual decline occurs following a young-adulthood pTBI and affects everyday life, no evidence for late midlife accelerated cognitive decline or dementia was found.

Intelligence in youth and health behaviours in middle age

ObjectiveWe investigated the association between intelligence in youth and a range of health-related behaviours in middle age. MethodParticipants were the 5347 men and women who responded to the National Longitudinal Survey of Youth 1979 (NLSY-79) 2012 survey. IQ was recorded with the Armed Forces Qualification Test (AFQT) when participants were aged 15 to 23 years of age. Self-reports on exercise (moderate activity, vigorous activity, and strength training), dietary, smoking, drinking, and oral health behaviours were recorded when participants were in middle age (mean age = 51.7 years). A series of regression analyses tested for an association between IQ in youth and the different health related behaviours in middle age, while adjusting for childhood socio-economic status (SES) and adult SES. ResultsHigher IQ in youth was significantly associated with the following behaviours that are beneficial to health: being more likely to be able to do moderate cardiovascular activity (Odds Ratio, 95% CI) (1.72, 1.35 to 2.20, p < .001) and strength training (1.61, 1.37 to 1.90, p < .001); being less likely to have had a sugary drink in the previous week (0.75, 0.71 to 0.80, p < .001); a lower likelihood of drinking alcohol heavily (0.67, 0.61 to 0.74, p < .001); being less likely to smoke (0.60, 0.56 to 0.65, p < .001); being more likely to floss (1.47, 1.35 to 1.59, p < .001); and being more likely to say they “often” read the nutritional information (1.20, 1.09 to 1.31, p < .001) and ingredients (1.24, 1.12 to 1.36, p < .001) on food packaging compared to always reading them. Higher IQ was also linked with dietary behaviours that may or may not be linked with poorer health outcomes (i.e. being more likely to have skipped a meal (1.10, 1.03 to 1.17, p = .005) and snacked between meals (1.37, 1.26 to 1.50, p < .001) in the previous week). An inverted u-shaped association was also found between IQ and the number of meals skipped per week. Higher IQ was also linked with behaviours that are known to be linked with poorer health (i.e. a higher likelihood of drinking alcohol compared to being abstinent from drinking alcohol (1.58, 1.47 to 1.69, p < .001)). A u-shaped association was found between IQ and the amount of alcohol consumed per week and an inverted u-shaped association was found between IQ and the number of cigarettes smoked a day. Across all outcomes, adjusting for childhood SES tended to attenuate the estimated effect size only slightly. Adjusting for adult SES led to more marked attenuation but statistical significance was maintained in most cases. ConclusionIn the present study, a higher IQ in adolescence was associated with a number of healthier behaviours in middle age. In contrast to these results, a few associations were also identified between higher intelligence and behaviours that may or may not be linked with poor health (i.e. skipping meals and snacking between meals) and with behaviours that are known to be linked with poor health (i.e. drinking alcohol and the number of cigarettes smoked). To explore mechanisms of association, future studies could test for a range of health behaviours as potential mediators between IQ and morbidity or mortality in later life.

Maternal and offspring intelligence in relation to BMI across childhood and adolescence

ObjectiveThe present study tested the association between both mothers’ and offspring’s intelligence and offspring’s body mass index (BMI) in youth.MethodParticipants were members of the National Longitudinal Survey of Youth 1979 (NLSY-79) Children and Young Adults cohort (n = 11,512) and their biological mothers who were members of the NLSY-79 (n = 4932). Offspring’s IQ was measured with the Peabody Individual Achievement Test (PIAT). Mothers’ IQ was measured with the Armed Forces Qualification Test (AFQT). A series of regression analyses tested the association between IQ and offspring’s BMI by age group, while adjusting for pre-pregnancy BMI and family SES. The analyses were stratified by sex and ethnicity (non-Black and non-Hispanic, Black, and Hispanic).ResultsThe following associations were observed in the fully adjusted analyses. For the non-Blacks and non-Hispanics, a SD increment in mothers’ IQ was negatively associated with daughters’ BMI across all age-groups, ranging from β = −0.12 (95% CI −0.22 to −0.02, p = 0.021) in late childhood, to β = −0.17 (95% C.I. −0.27 to −0.07, p = 0001), in early adolescence and a SD increment in boys’ IQ was positively associated with their BMI in early adolescence β = 0.09 (95% CI 0.01–0.18, p = 0.031). For Blacks, there was a non-linear relationship between mothers’ IQ and daughters’ BMI across childhood and between girls’ IQ and BMI across adolescence. There was a positive association between mothers’ IQ and sons’ BMI in early adolescence (β = 0.17, 95% CI 0.02–0.32, p = 0.030). For Hispanic boys, there was a positive IQ-BMI association in late childhood (β = 0.19, 95% CI 0.05–0.33, p = 0.008) and early adolescence (β = 0.17, 95% CI 0.04–0.31, p = 0.014).ConclusionMothers’ IQ and offspring’s IQ were associated with offspring’s BMI. The relationships varied in direction and strength across ethnicity, age group and sex. Obesity interventions may benefit from acknowledging the heterogeneous influence that intelligence has on childhood BMI.

Military Officer Aptitude in the All-Volunteer Force

We show a statistically significant and quantitatively meaningful decline in the aptitude of commissioned officers in the marine corp from 1980 to 2014 as measured by their scores on the General Classification Test. This result contrasts with the widely studied increase in the quality of enlisted personnel since 1973 when conscription ended. As a possible cause for this decline, we focus on the fact that, during this period, marine officers had to have a 4-year college degree and there has been an expansion of the pool of young Americans in college. To corroborate this hypothesis, we show that there has been a similar decline in scores on the Armed Forces Qualification Test for responders to the 1979 and 1997 National Longitudinal Surveys of Youth among college graduates but not for the overall set of respondents.

Intelligence in youth and mental health at age 50

BackgroundFew cognitive epidemiology studies on mental health have focused on the links between pre-morbid intelligence and self-reports of common mental disorders, such as depression, sleep difficulties, and mental health status. The current study examines these associations in 50-year-old adults. MethodsThe study uses data from the 5793 participants in the National Longitudinal Survey of Youth 1979 cohort (NLSY-79) who responded to questions on mental health at age 50 and had IQ measured with the Armed Forces Qualification Test (AFQT) when they were aged between 15 and 23years in 1980. Mental health outcomes were: life-time diagnosis of depression; the mental component score of the 12-item short-form Health Survey (SF-12); the 7-item Center for Epidemiological Studies Depression Scale (CES-D); and a summary measure of sleep difficulty. Results & conclusionHigher intelligence in youth is associated with a reduced risk of self-reported mental health problems at age 50, with age-at-first-interview and sex adjusted Bs as follows: CES-depression (B=−0.16, C.I. −0.19 to −0.12, p<0.001), sleep difficulties (B=−0.11, C.I. −0.13 to −0.08, p<0.001), and SF-12 mental health status (OR=0.78, C.I. 0.72 to 0.85, p<0.001; r=−0.03 p=0.075). Conversely, intelligence in youth is linked with an increased risk of receiving a diagnosis of depression by the age of 50 (OR 1.11, C.I. 1.01 to 1.22, p=0.024; r=0.03, p=0.109). No sex differences were observed in the associations. Adjusting for adult SES accounted for most of the association between IQ and the mental health outcomes, except for having reported a diagnosis of depression, in which case adjusting for adult SES led to an increase in the size of the positive association (OR=1.32, C.I. 1.16 to 1.51, p<0.001).

Association Between Long-Term Cognitive Decline in Vietnam Veterans With TBI and Caregiver Attachment Style

To examine whether a caregiver's attachment style is associated with patient cognitive trajectory after traumatic brain injury (TBI). National Institute of Neurological Disorders and Stroke, National Institutes of Health, Bethesda, Maryland. Forty Vietnam War veterans with TBI and their caregivers. Cognitive performance, measured by the Armed Forces Qualification Test percentile score, completed at 2 time points: preinjury and 40 years postinjury. On the basis of caregivers' attachment style (secure, fearful, preoccupied, dismissing), participants with TBI were grouped into a high or low group. To examine the association between cognitive trajectory of participants with TBI and caregivers' attachment style, we ran four 2 × 2 analysis of covariance on cognitive performances. After controlling for other factors, cognitive decline was more pronounced in participants with TBI with a high fearful caregiver than among those with a low fearful caregiver. Other attachment styles were not associated with decline. Caregiver fearful attachment style is associated with a significant decline in cognitive status after TBI. We interpret this result in the context of the neural plasticity and cognitive reserve literatures. Finally, we discuss its impact on patient demand for healthcare services and potential interventions.

Individual differences in cognitive ability at age 20 predict pulmonary function 35 years later

BackgroundPoor pulmonary function is associated with mortality and age-related diseases, and can affect cognitive performance. However, extant longitudinal studies indicate that early cognitive ability also affects later pulmonary function. Despite...

DISCOUNTING, COGNITION, AND FINANCIAL AWARENESS: NEW EVIDENCE FROM A CHANGE IN THE MILITARY RETIREMENT SYSTEM

The choice given military personnel between an immediate cash payment of $30,000 or a more generous retirement pension permits us to estimate individuals' personal discount rates (PDRs). The resulting PDRs, about 7% for enlisted personnel and 2%–4.3% for officers, are precise and are correlated with a variety of other financial behaviors. The PDR is negatively related to educational attainment and the Armed Forces Qualification Test, but cognition seems to operate through channels other than being better informed; better‐informed individuals were not always measured to be more patient. (JEL D91, D14)

Development of a Cyber/Information Technology Knowledge Test for Military Enlisted Technical Training Qualification

An Armed Services Vocational Aptitude Battery (ASVAB) Review Panel, with expertise in personnel selection, job classification, psychometrics, and cognitive psychology developed recommendations for changes to the military enlistment test battery. One recommendation was to develop and evaluate a test of cyber/information and communications technology literacy to supplement current ASVAB content. This article summarizes a multiphased Cyber Test development process: (a) a review of information/computer technology literacy definitions and measures, (b) development and pilot testing of a cyber knowledge measure, (c) validation of test scores against final school grades (FSGs) for selected technical training courses, (d) development of an operational reporting metric and subgroup norms, and (e) examination of construct validity. Results indicate the Cyber Test has predictive validity versus technical training school grades and incremental validity comparable to the ASVAB technical knowledge tests when used with the ASVAB Armed Forces Qualification Test (AFQT) verbal/math composite as a baseline.

Rates of Knee Injury in the U.S. Active Duty Army, 2000–2005

We sought to summarize knee injuries (KI) in the U.S. Active Duty Army (ADA) in terms of absolute numbers, examine current rate trends, and identify ADA who were at increased risk for experiencing a KI. We used the Total Army Injury and Health Outcomes Database (TAIHOD) to compute unadjusted and adjusted rates of KI, categorized by the Barell Matrix, within the ADA for the years 2000-2005. During this period, 21 to 25 per 1,000 ADA suffered from KI. The highest yearly rates were observed for knee dislocation and sprains/strains (31 per 1,000 ADA). In ADA with a history of a KI (within 2 years), rates increased nearly tenfold. Elevated KI rates were also seen in ADA with prior upper or lower leg injuries, those > 30 years of age, and those with a category IV Armed Forces Qualification Test score (lowest admissible in Army). ADA KI rates remained fairly stable throughout the study period. Relative to other ADA Soldiers, those with prior knee, upper leg, or lower leg injuries are at increased risk for subsequent KI.
