Personality tests are reliable and valid tools that can aid organizations in identifying suitable employees. They provide utility for maximizing organizational productivity and for avoiding claims of negligent hiring. When properly deployed, personality tests (both normal and abnormal/clinical) pose little threat of violating individuals’ rights under the Americans with Disabilities Act (ADA) or other Equal Employment Opportunity–related laws and regulations. As evidenced by a dearth of successful legal challenges, even with increasing use of personality tests in recent years, organizations have become educated and sophisticated with regard to the ethical and legal use of such tests in employment settings. We predict this trend will continue, incorporating recent developments relating to contemporary models of psychopathology (Kotov et al., 2017; Markon, Krueger, & Watson, 2005), neurobiologically informed theoretical explanations of psychopathology (DeYoung & Krueger, 2018), and the alternative model of personality disorders (AMPD) included in the most recent edition of the American Psychiatric Association’s (APA) Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition; DSM-5).

This chapter summarizes important issues surrounding the use of cognitive ability tests in organizational settings, and highlights new developments that are becoming particularly pertinent given demographic changes in many societies and international economic trends (e.g., age differences, cross-cultural assessment, internet-based testing).

Local language proficiency is often regarded as a key enabling factor for expatriate success. In this study, we use data from the iGOES project to examine how language proficiency contributes to expatriate outcomes. Language proficiency is negligibly to weakly related to most outcomes, but does show positive relations with interaction adjustment. Moderator analyses support the interpretation of this relation as reflecting increased comfort from being able to communicate effectively, rather than reflecting cultural engagement or social inclusion effects. Overall, results indicate that local language proficiency can contribute to expatriate comfort, but is not absolutely necessary for expatriate success.

Empirical benchmarks for interpreting effect size variability in meta-analysis

Generalization in meta-analyses is not a dichotomous decision (typically encountered in papers using the Q test for homogeneity, the 75% rule, or null hypothesis tests). Inattention to effect size variability in meta-analyses may stem from a lack of guidelines for interpreting credibility intervals. In this commentary, we describe two methods for making practical interpretations and determining whether a particular SDρ represents a meaningful level of variability.

In this chapter, we update the issues and evidence, and describe the emerging consensus about the usefulness of personality variables in employee selection. We describe the mega-trends that have influenced the personality variables that are selected for inclusion in selection systems, how they are measured, and the outcomes they are expected to predict. We describe factors that hinder our understanding and those that help increase our knowledge of personality variables and their role in more accurately predicting work-related criteria. We address issues related to taxonomic structure, measurement methods, level of measurement, validity, and factors that threaten and enhance the validity of personality measures.

Cognitive ability: Measurement and validity for employee selection

In this chapter, we provide an overview of cognitive ability’s key role in staffing organizations and provide evidence-based practice recommendations. We first present a brief synopsis of the history, current usage, and acceptance of cognitive ability tests in employee selection. Second, we highlight the theoretical underpinnings and structure of cognitive ability as a construct. Third, we discuss developments in its measurement. Fourth, we present an overview of the criterion-related validity of cognitive ability tests in predicting valued work behaviors and outcomes, including non-task-performance criteria that have been increasingly investigated in recent years. Fifth, we discuss the issue of group differences in cognitive ability test scores both within the United States and internationally. We conclude by discussing future research and challenges facing organizations that intend to use cognitive ability tests in making employee selection decisions.

Creative interests and personality: Scientific versus artistic creativity

The present study used intraindividual criterion profile analysis to investigate the relationship between creative artistic and investigative interests and the Big Five personality traits. In 19 samples, we found that artistic and investigative interests showed distinct intraindividual personality profile patterns. Investigative interests were associated with elevated openness to intellect, conscientiousness, and emotional stability and low extraversion and agreeableness, relative to individuals’ other traits. Artistic interests were associated with personal strengths for openness to experiences and personal weaknesses for conscientiousness, assertiveness, and emotional stability. Across creative interests, profile pattern, not absolute trait level, drove the relationship between personality traits and interests. These findings replicated across numerous personality inventories and levels of interest specificity (RIASEC, basic interests, occupation-specific interests). We discuss the implications of these results for the complementary use of personality and interest scales in vocational counseling and personnel selection.

Cognitive predictors and age-based adverse impact among business executives

Age differences on measures of general mental ability and specific cognitive abilities were examined in 2 samples of job applicants to executive positions as well as a mix of executive/nonexecutive positions to determine which predictors might lead to age-based adverse impact in making selection and advancement decisions. Generalizability of the pattern of findings was also investigated in 2 samples from the general adult population. Age was negatively related to general mental ability, with older executives scoring lower than younger executives. For specific ability components, the direction and magnitude of age differences depended on the specific ability in question. Older executives scored higher on verbal ability, a measure most often associated with crystallized intelligence. This finding generalized across samples examined in this study. Also, consistent with findings that fluid abilities decline with age, older executives scored somewhat lower on figural reasoning than younger executives, and much lower on a letter series test of inductive reasoning. Other measures of inductive reasoning, such as Raven’s Advanced Progressive Matrices, also showed similar age group mean differences across settings. Implications for employee selection and adverse impact on older job candidates are discussed.

Maladaptive personality constructs, measures, and work behaviors: Scientific background and employment practice recommendations

(2014)

Important changes have been occurring in the clinical psychology literature that are relevant to how maladaptive personality characteristics are conceptualized, measured, and used in workplace applications. We aim to clarify distinctions among maladaptive personality traits, measures of maladaptive personality constructs, and their behavioral consequences at work. In pursuing a connection between the industrial–organizational (I–O) and clinical psychology literatures on maladaptive personality, we distinguish maladaptive constructs, maladaptive measures, and maladaptive work behaviors. Conceptual clarification and linguistic precision are essential, as their distinctions are not merely academic but have important consequences for workplace research and practice.

Review of Non-Verbal IQ Test

This review provides information about the development, reliability, and validity of the Non-Verbal IQ Test (NVIQT). The NVIQT is a nonverbal measure of cognitive ability, developed to assess spatial ability and pattern recognition. The stated purpose of the test is to serve as a measure of intelligence that minimizes irrelevant cultural or educational influences on test scores. The technical manual accompanying the test does not further delineate the nature of the construct that the test is intended to assess. Limited information is provided on the intended target population or intended uses of the test…
