Combining personality and cognitive ability predictors for hiring service-oriented employees

Recent developments in personality theory and assessment have led to calls for inclusion of personality measures in personnel selection. A measure of service-oriented personality was used in conjunction with cognitive and perceptual ability tests in a concurrent validation study of 202 medical clerical positions. The ability tests explained 5% of criterion variance; an additional 5–8% was accounted for by the personality measures. The results were interpreted as tentative support for broadening use of personality measurement in personnel selection, although a need for greater attention to construct validation was also emphasized.We would like to acknowledge the financial assistance provided by the University of Colorado Graduate School of Business for data entry and analysis, as well as the cooperation of the National Computer Systems Corporation and of Kaiser Permanente and its employees. We are also indebted to Garth Coombs, Deborah Crown, and Chuck Hulin for their insightful comments.     

Too much of a good thing: curvilinear relationships between personality traits and job performance

The relationships between personality traits and performance are often assumed to be linear. This assumption has been challenged conceptually and empirically, but results to date have been inconclusive. In the current study, we took a theory-driven approach in systematically addressing this issue. Results based on two different samples generally supported our expectations of the curvilinear relationships between personality traits, including Conscientiousness and Emotional Stability, and job performance dimensions, including task performance, organizational citizenship behavior, and counterproductive work behaviors. We also hypothesized and found that job complexity moderated the curvilinear personality–performance relationships such that the inflection points after which the relationships disappear were lower for low-complexity jobs than they were for high-complexity jobs. This finding suggests that high levels of the two personality traits examined are more beneficial for performance in high- than low-complexity jobs. We conclude by discussing the implications of these findings for the use of personality in personnel selection.     

GROUP DIFFERENCES IN PERSONALITY: META‐ANALYSES COMPARING FIVE U.S. RACIAL GROUPS

This research poses 2 applied questions: How large are racial group differences on personality scales and are these differences likely to cause adverse impact in personnel selection? We examined the extent to which racial groups differ across Big 5 personality factors and facets. Large‐scale, quantitative estimates based on over 700 effect sizes were meta‐analytically summarized. Multiple personality instruments and understudied racial groups, particularly Asian Americans and American Indians, were included in the meta‐analyses. Most group comparisons and personality scales yielded negligible differences and are not likely to cause adverse impact in selection. However, facet‐level analyses produced different d‐values, with some group comparisons showing moderate differences, suggesting that the use of personality measures in selection does not uniformly circumvent adverse impact concerns. The veracity of this conclusion depends on (a) the particular trait in question, (b) the composition of the applicant pool (i.e., which groups are to be compared with one another), (c) the effect size (i.e., d‐value), and (d) the selection ratio. For practitioners, we present a quantitatively informed summary of when and where to expect adverse impact to result from personality measures used in personnel selection.     

Perceptions of the utility of personality assessment for personnel selection in the South African context: An exploratory study

This study explored South African industrial psychologists’ perceptions of the utility of personality assessment for personnel selection. Eleven industrial psychologists (2 male, 9 female) from the Johannesburg area, South Africa were the participants. They participated in semi-structured interviews exploring their understanding of the place of personality assessment in personnel selection within organisational settings in South Africa and the common practices employed. Thematic analysis was used to analyse the data. Four dominant themes emerged from the data: person-environment fit; specific uses of personality tests; commonly used tests and validity and ethical concerns. Based on the findings, personality assessment use in South African industry settings appears multi-layered and consistently evolving.     

NEW DEVELOPMENTS IN THE USE OF MEASURES OF HONESTY INTEGRITY, CONSCIENTIOUSNESS, DEPENDABILITY TRUSTWORTHINESS, AND RELIABILITY FOR PERSONNEL SELECTION

This paper is the fourth in a series of reviews of the use of measures of honesty, integrity, conscientiousness, dependability, trustworthiness, and reliability for personnel selection (see Sackett & Decker, 1979; Sackett & Harris, 1984; Sackett, Burris, & Callahan, 1989). New developments reviewed include an examination of professional and congressional inquiry into this area of testing, rapid growth of the validity data base, new insight into similarities and differences between different tests, and links to the Big Five personality dimensions. Inquiries into relationships with other constructs, including cognitive ability, moral reasoning, and social desirability are reviewed, as are applicant reactions to these tests. The effects of the Civil Rights Act of 1991 and the Americans with Disabilities Act are considered.     

Correcting Personality Tests for Faking: A Review of Popular Personality Tests and an Initial Survey of Researchers

We reviewed a number of personality tests that are commonly used for personnel selection and found that some of the more popular tests provide a “correction” for faking. Additionally, a survey of researchers' preferences regarding correcting personality test scores for faking was conducted. The respondents, who were experienced in using personality tests for industrial‐organizational purposes, generally favored the use of faking corrections (69% were in favor). The apparently common practice of correcting personality scores for faking was contrasted with relevant conceptual, empirical, and statistical concerns as to the advisability of applying the correction for faking.     

Personality characteristics that are valued in teams: Not always “more is better”?

This study investigates the relationships between personality traits and contributions to teamwork that are often assumed to be linear. We use a theory‐driven approach to propose that extraversion, agreeableness and conscientiousness have inverted U‐shaped relationships with contributions to teamwork. In a sample of 220 participants asked to perform a creative task in teams, we found that extraversion, agreeableness and conscientiousness were curvilinearly associated with peer‐rated contributions to teamwork in such a way that the associations were positive, with a decreasing slope, up to a peak, and then they became negative as personality scores further increased. We replicated the results concerning the non‐linear association between extraversion, conscientiousness and peer‐rated contributions to teamwork in a sample of 314 participants engaged in a collaborative learning exercise. Our results support recent claims and empirical evidence that explorations of personality–work‐related behaviours relationships should move beyond the linearity assumptions. We conclude by discussing the implications of our research for personnel selection.     

ARE WE GETTING FOOLED AGAIN? COMING TO TERMS WITH LIMITATIONS IN THE USE OF PERSONALITY TESTS FOR PERSONNEL SELECTION

We recently published an article in which we highlighted a number of issues associated with the use of self-report personality tests in personnel selection contexts ( Morgeson et al., 2007 ). Both Ones, Dilchert, Viswesvaran, and Judge (2007) and Tett and Christiansen (2007) have written responses to this article. In our response to these articles we address many of the issues raised by Ones et al. and Tett and Christiansen. In addition to a detailed response, we make the following 4 key points: (1) Our criticisms of personality testing apply only to the selection context, not to all research on personality; (2) the observed validities of personality tests predicting job performance criteria are low and have not changed much over time; (3) when evaluating the usefulness of using personality tests to select applicants, one must not ignore the observed, uncorrected validity; and (4) when discussing the value of personality tests for selection contexts, the most important criteria are those that reflect job performance. Implications for personality testing research and practice are discussed.     

Emotional Intelligence in Selection Contexts: Measurement method,criterion‐related validity,and vulnerability to response distortion

Two studies examined aspects of the validity of self‐report and performance‐based measures of emotional intelligence (EI) relevant to their use in personnel selection. In Study 1, structural equation modeling indicated that a two‐factor model with separate factors for the two types of EI measures fit better than a one‐factor solution. The performance‐based EI factor was more related to cognitive ability (R=.38) than personality (R=.26), whereas the self‐report EI factor was more related to personality (R=.85) than cognitive ability (R=.09). Although the performance‐based EI factor correlated more strongly with job performance (ρ=.24) than did that of the self‐report (ρ=.05), it provided little incremental validity beyond cognitive ability and conscientiousness. In Study 2, participants were asked to complete the measures as if applying for a job, and mean scores were then compared with those of Study 1. Results indicated that self‐report EI measures were more vulnerable to distortion than were the performance‐based measures. Implications for the assessment of EI in personnel selection contexts are discussed.     

Measurement Equivalence Between Applicant and Incumbent Groups: An IRT Analysis of Personality Scales

Incumbents are often used in the development and validation of a wide variety of personnel selection instruments, including noncognitive instruments such as personality tests. However, the degree to which assumed motivational factors impact the measurement equivalence and validity of tests developed using incumbents has not been adequately addressed. This study addressed this issue by examining the measurement equivalence of 6 personality scales between a group applying for jobs as sales managers in a large retail organization (N = 999) and a group of sales managers currently employed in that organization (N = 796). A graded item response theory model (Samejima, 1969) was fit to the personality scales in each group. Results indicated that moderately large differences existed in personality scale scores (approximately 1/2 standard deviation units) but only one of the six scales contained any items that evidenced differential item functioning and no scales evidenced differential test functioning. In addition, person-level analyses showed no apparent differences across groups in aberrant responding. The results suggest that personality measures used for selection retain similar psychometric properties to those used in incumbent validation studies.     

PERSONALITY TESTS AT THE CROSSROADS: A RESPONSE TO MORGESON, CAMPION, DIPBOYE, HOLLENBECK, MURPHY, AND SCHMITT (2007)

Despite widespread and growing acceptance that published personality tests are valid predictors of job performance, Morgeson et al. (2007) propose they be abandoned in personnel selection because average validity estimates are low. Our review of the literature shows that Morgeson et al.'s skepticism is unfounded. Meta-analyses have demonstrated that published personality tests, in fact, yield useful validity estimates when validation is based on confirmatory research using job analysis and taking into account the bidirectionality of trait–performance linkages. Further gains are likely by use of narrow over broad measures, multivariate prediction, and theory attuned to the complexities of trait expression and evaluation at work. Morgeson et al. also suggest that faking has little, if any, impact on personality test validity and that it may even contribute positively to job performance. Job applicant research suggests that faking under true hiring conditions attenuates personality test validity but that validity is still sufficiently strong to warrant personality test use in hiring. Contrary to Morgeson et al., we argue that the full value of published personality tests in organizations has yet to be realized, calling for programmatic theory-driven research.     

Toward a new approach to the study of personality in culture

We review recent developments in the study of culture and personality measurement. Three approaches are described: an etic approach that focuses on establishing measurement equivalence in imported measures of personality, an emic (indigenous) approach that studies personality in specific cultures, and a combined emic-etic approach to personality. We propose the latter approach as a way of combining the methodological rigor of the etic approach and the cultural sensitivity of the emic approach. The combined approach is illustrated by two examples: the first with origins in Chinese culture and the second in South Africa. The article ends with a discussion of the theoretical and practical implications of the combined emic-etic approach for the study of culture and personality and for psychology as a science.     

Using the BIDR to Distinguish the Effects of Impression Management and Self‐Deception on the Criterion Validity of Personality Measures: A Meta‐Analysis

Although the use of personality tests for personnel selection has gained increasing acceptance, researchers have raised concerns that job applicants may distort their responses to inflate their scores. In the present meta‐analysis, we examined the effects of the two dimensions of social desirability, impression management and self‐deception, on the criterion validity of personality constructs using the balanced inventory of desirable responding (BIDR). The results indicate that impression management and self‐deception did not create spurious effects on the relationship between personality measures and performance, nor did they function as performance predictors. Moreover, removing the influence of impression management or self‐deception from personality measures did not substantially attenuate the criterion validity of personality variables. Implications of the results and directions for future research are also discussed.     

Personality and absenteeism: a meta‐analysis of integrity tests

Until recently, research focus has been on a variety of demographic, attitudinal, and organizational variables in predicting and explaining absenteeism. If personality traits predict absenteeism, then it may be possible to use measures of these traits to identify and select job applicants and thereby reduce absenteeism rates. In this research, our goal was to examine whether integrity tests could be used to predict absenteeism. Meta‐analysis was applied to studies of the validity of pre‐employment integrity tests for predicting voluntary absenteeism. Twenty‐eight studies based on a total sample of 13 972 were meta‐analysed. The estimated mean predictive validity of personality‐based integrity tests was 0.33. This operational validity generalized across various predictor scales, organizations, settings, and jobs (SD_ρ = 0.00). Overt integrity tests, however, showed much lower predictive validity for absenteeism and greater variability than personality‐based tests (ρ = 0.09; SD_ρ = 0.16). The results indicate that a personnel selection approach to reducing absenteeism in organizations may be a useful strategy, particularly if personality‐based integrity tests are utilized. Potential explanations for differences between these results and those found for Big Five measures of personality are offered. Future research investigating models of absenteeism should incorporate the personality constructs assessed by integrity tests. Copyright © 2003 John Wiley & Sons, Ltd.     

THE BIG FIVE PERSONALITY DIMENSIONS AND JOB PERFORMANCE: A META-ANALYSIS

This study investigated the relation of the "Big Five" personality dimensions (Extraversion, Emotional Stability, Agreeableness, Conscientiousness, and Openness to Experience) to three job performance criteria (job proficiency, training proficiency, and personnel data) for five occupational groups (professionals, police, managers, sales, and skilled/semi-skilled). Results indicated that one dimension of personality, Conscientiousness, showed consistent relations with all job performance criteria for all occupational groups. For the remaining personality dimensions, the estimated true score correlations varied by occupational group and criterion type. Extraversion was a valid predictor for two occupations involving social interaction, managers and sales (across criterion types). Also, both Openness to Experience and Extraversion were valid predictors of the training proficiency criterion (across occupations). Other personality dimensions were also found to be valid predictors for some occupations and some criterion types, but the magnitude of the estimated true score correlations was small (ρ < .10). Overall, the results illustrate the benefits of using the 5-factor model of personality to accumulate and communicate empirical findings. The findings have numerous implications for research and practice in personnel psychology , especially in the subfields of personnel selection, training and development, and performance appraisal.     

Development and preliminary validation of a semi-structured interview for the screening of law enforcement candidates

A standard practice among most law enforcement agencies is to include psychological screening in the selection of job candidates. Although the use of personality tests in predicting job performance of law enforcement officers has received empirical support (e.g., the Minnesota Multiphasic Personality Inventory, the Inwald Personality Inventory), there is a conspicuous absence of data regarding the reliability and validity of interview procedures. The present study represents the first step in the development of a standardized, semi-structured interview for use in the screening of law enforcement personnel. This interview, the Law Enforcement Candidate Interview, was constructed using content areas drawn from measures used in the screening of law enforcement personnel (e.g., Inwald Personality Inventory) and assessment of personality functioning (Structured Clinical Interview for DSM-III-R Personality Disorders). This interview was then administered by two doctoral students to a group of law enforcement academy cadets (n=34). A modest degree of inter-rater reliability was achieved, although internal consistency was somewhat lacking. Interview scores were correlated with measures of academy performance (final grade-point average and peer and supervisor ranking of academy performance). Results of these analyses suggest the LECI is a modest predictor of academy performance. Potential uses of the LECI and future research indications are outlined.     

Emotional Intelligence in Personnel Selection: Applicant reactions,criterion, and incremental validity

In two studies, based on four samples and more than 600 participants, the authors examined applicant reactions, criterion and incremental validity, and differential prediction of emotional intelligence (EI) in personnel selection using the Mayer–Salovey–Caruso Emotional Intelligence Test. The first study examined applicant reactions in terms of face validity and fairness evaluation of the EI test. The second study examined across three samples (salespeople, front‐desk public employees, and hospital chief executive officers) the criterion validity, incremental validity, and differential prediction of EI. Results suggest that the EI test is perceived as a fair selection tool, and is predictive of performance. The EI test has incremental validity over cognitive abilities and personality (big five) when predicting subjective and objective performance criteria. Based on these results, the authors encourage further research on the use of EI in selection settings.     

FIVE REASONS WHY THE "BIG FIVE" ARTICLE HAS BEEN FREQUENTLY CITED

This study investigated the relation of the "Big Five" personality dimensions (Extraversion, Emotional Stability, Agreeableness, Conscientiousness, and Openness to Experience) to three job performance criteria (job proficiency, training proficiency, and personnel data) for five occupational groups (professionals, police, managers, sales, and skill/semi-skilled). Results indicated that one dimension of personality, Conscientiousness, showed consistent relations with all job performance criteria for all occupational groups. For the remaining personality dimensions, the estimated true score correlations varied by occupational group and criterion type. Extraversion was a valid predictor for two occupations involving social interaction, managers and sales (across criterion types). Also, both Openness to Experience and Extraversion were valid predictors of the training proficiency criterion (across occupations). Other personality dimensions were also found to be valid predictors for some occupations and some criterion types, but the magnitude of the estimated true score correlations was small ( p <10). Overall, the results illustrate the benefits of using the 5-factor model of personality to accumulate and communicate empirical findings. The findings have numerous implications for research and practice in personnel psychology, especially in the subfields of personnel selection, training and development, and performance appraisal.     

Examen des pratiques d'évaluation en recrutement et en bilan de compétences

Using two empirical studies, this article compare assessment methods and tools used in personnel selection and career counseling. Subjects are requested to point up their methods and assessment tools, on the one hand by 327 recruiters, on the other hand, by 318 competences reports. The results indicated a spread tendency to use interview and personality assessment tools. This spread tendency to use work psychology tools whatever the assessment context raises thought about choices and representations associated with psychometrical methods.     

SOME NEW FRONTIERS IN PERSONNEL SELECTION RESEARCH

Current research developments in several areas of personnel selection methodology are reviewed. The areas reviewed represent attempts to develop alternatives to traditional paper-and-pencil methods of test development. These areas include computer-interactive tests in the employment situation, new ways of using life-history information, the use of physical tests in selecting individuals for physically demanding jobs, and the development of job-related medical standards for job assignment.
