May mega research update

It's time once again for the monthly research round-up.  So let's dive right in:

The June International Journal of Selection and Assessment doesn't disappoint; let's take a look:

- More evidence of the link between personality variables and CWBs; this time with concurrent data in China

- Dovetailing nicely with a post I've been working on regarding promotional testing, this research indicates some interesting characteristics of internal test takers

- Why are supervisors open to behavioral interviews but shun discussion of "structure"?  Looks like how we communicate about them plays a big role.

- More research on self-efficacy, this time teasing apart the concept a bit.

- Always a popular topic: applicant reactions to selection mechanisms.  This time with a sample from Saudi Arabia.

- Speaking of applicant reactions...how about another study?  This one comparing U.S. and Vietnamese college students.  By the way, not surprisingly work samples came out a winner in both of these studies.

- Next, a fascinating study of a hidden bonus to UIT: despite the cheating element, it likely increases your candidate pool and eventually performance outcomes

- Speaking of response distortion, here's another study, this time of military cadet selection using personality inventories

- Okay, one more on inflation.  This time a study of Chinese applicants--no difference compared to American samples.

- Back in March I wrote about a study Jeremy Bernerth published in J.A.P.  that got a lot of attention.  This time, Bernerth studied ethnic differences and found minority status was negatively related to credit scores.


Moving on to the summer issue of Personnel Psychology:

-  The "file drawer problem" is the theory that nonsignificant results are less likely to get published.  According to this study, that appears unlikely.  But IMHO looking at all correlations is different than looking at the correlations key to one's hypothesis(es)...

- Back to faking (that may be this post's theme!), can response elaboration reduce faking on biodata items?  This study suggests so.  Although I'm left wondering...what was the impact on validity?

- Speaking of biodata, there are various ways of keying these items.  This research suggests the best method depends on your sample size, although rational keying performed the worst.


How about the May issue of Journal of Applied Psychology?

-  Well this is interesting...Chad Van Iddekinge and his colleagues have provided an updated meta-analysis on the criterion-related validity of integrity tests.  What did they find? Well, the results appear to be less promising than those published previously (e.g., corrected r=.18 for job performance).  Much like SIOP's research journal, this time J.A.P. published several commentaries in response to the study that...well, let's just say a debate ensued about the analysis...

- The Dark Triad.  It sounds like something in a Dan Brown novel.  But in this meta-analysis the authors show that personality characteristics that make up this triad (Machiavellianism, narcissism, and psychopathy) explain some variance in CWBs.

- Why are some people more proactive in seeking career goals than others?  It's an important and under-researched question.  In this study the authors show that part of the explanation lies in "future work selves", or how people's hopes and aspirations as they relate to work.

- Think self-reports of CWBs are biased?  Perhaps not, according to this new study.

- Interested in what causes proactive customer service behavior?  According to this multi-national study, self-efficacy is a key (along with service climate).

- Why do some leaders engage in more self-interested behavior than others?  Perhaps not surprisingly, it appears due in part to the strength of their moral identity.


The May issue of the Journal of Applied Social Psychology has a couple gems...

- Hey, look, turns out being sensitive to your subordinates pays off.  Talk about a lesson that needs frequent repeating...

- And that's it.  Oh, wait, just this little study about using Facebook profiles to predict job performance...that I wrote about before....available in FULL right now...


Okay, getting to the end...The May/June issue of HRM:

- An interesting study of adverse impact in promotion decisions for managers in a Fortune 500 retailer.  The authors compared three methods (top-down assessment, assessment centers, and  multisource appraisal) and the results demonstrate how complex these analyses are!

- Speaking of complex.  Think that successful job postings on the web is just fancy graphics?  Think again--it still involves some classic factors like the labor market, firm reputation, and compensation incentives.  The more things change...

- Identifying future leaders.  There are few other issues that are as important for most organizations.  Yet how exactly to do it eludes many.  These authors propose a model that focuses on four main features: analytical ability, learning agility, drive, and emergent leadership.


Finally, a few from PARE:

- Does item order impact response anxiety?  Not according to this study.

- What's that?  How do we use a new jacknife procedure to eliminating items and improve structural equation modeling?  You're in luck.

- Looks like a lot of research rely on beta weights when interpreting and reporting multiple linear regression results.  But there's so much more...


Happy reading!

IJSA v.19 #2: Personality, personality, personality (and more)

The June 2011 issue of the International Journal of Selection and Assessment (IJSA, volume 19, issue 2) is out. And it's chalk full of articles on personality measurement, but includes other topics as well, so let's jump in! Warning: lots of content ahead.

- O'Brien and LaHuis analyzed applicant and incumbent responses to the 16PF personality inventory and found differential item functioning for over half the items (but of those only 20% were in the hypothesized direction!).

- Reddock, et al. report on an interesting study of personality scores and cognitive ability predicting GPA among students. "At school" frame-of-reference instructions increased validity and, even more interesting, within-person inconsistency on personality dimensions increased validity beyond conscientiousness and ability.

- Fein & Klein introduce a creative approach: using combinations of facets of Five-Factor Model traits to predict outcomes. Specifically, the authors found that a combination (e.g., assertiveness, activity, deliberation) did as well or better in predicting behavioral self-regulation compared to any single facet or trait.

- Think openness to experience is the runt of the FFM? Mussel, et al. would beg to disagree. The authors argue that subdimensions and facets of openness (e.g., curiosity, creativity) are highly relevant for the workplace and understudied--and demonstrate differential criterion-related and construct validity.

- So just when you're thinking to yourself, "hey, I'm liking this subdimension/facet approach), along comes van der Linden, et al. with a study of the so-called General Factor of Personality (GFP) that is proposed to occupy a place at the top of the personality structure hierarchy. The authors studied over 20,000 members of the Netherlands armed forces (fun facts: active force of 61,000, 1.65% of GDP) and found evidence that supports a GFP and value in its measurement (i.e., it predicted dropping out from military training). Unsurprisingly, not everyone is on the GFP bus.

- Next, another fascinating study by Robie et al. on the impact of the economy on incumbent leaders' personality scores. In their sample of US bank employees, as unemployment went up, so did personality inventory results. Faking or environmental impact? Fun coffee break discussion.

- Recruiters, through training and years of experience, are better at judging applicant personality than laypersons, right? Sort of. Mast, et al. found that while recruiters were better at judging the "global personality profile" of videotaped applicants as well as detecting lies, laypeople (students in this case) were better at judging specific personality traits.

- Last one on the personality front: Iliescu, et al. report the results of a study of the Employee Screening Questionnaire (ESQ), a well-known covert, forced-choice integrity measure. Scores showed high criterion-related validity, particularly for counterproductive work behaviors.

- Okay, let's move away from personality testing. Ziegler, et al. present a meta-analysis of predicting training success using g, specific abilities, and interviews. The authors were curious whether the dominant paradigm that g is the single best predictor would hold up in a single sample. Answer? Yep. But specific abilities and structured interviews were valuable additions (unstructured interviews--not so much), and job complexity moderated some of the relationships.

- Given their popularity and long history, it's surprising that there isn't more research on role-players in assessment centers (ACs). Schollaert and Lievens aim to rectify this by investigating the utility of predetermined prompts for role-players during ACs. Turns out there are advantages for measuring certain dimensions (problem solving, interpersonal sensitivity). Sounds promising to me. Fortunately you can read the article here.

- What's the best way to combine assessment scores into an overall profile? Depends who you ask. Diab, et al. gathered information from a sample of adults and found that those in the U.S. preferred holistic over mechanical integration of both interview and other test scores, whereas those outside the U.S. preferred holistic for interview scores only.

- Still with me? Last but not least, re-testing effects are a persistent concern, particularly on knowledge-based tests. Dunlop et al. looked at a sample of firefighter applicants and found the largest practice effects for abstract reasoning and mechanical comprehension (both timed)--although even those were only two-fifths of a standard deviation. Smaller effects were found for a timed test of numerical comprehension ability and an untimed situational judgment test. For all four tests, practice effects diminished to non-significance upon a third session.

September 2010 IJSA (those considering SHRM certification, read on)

The September issue of the International Journal of Selection and Assessment (IJSA) is out with a boatload of content. Let's check out some of the highlights:

First up, a piece by Gentry, et al. that has implications for self-rating instruments. The authors studied self-observer ratings among managers in Southern Asia and Confucian Asia and found an important difference: the discrepancy between the ratings was greater in Southern Asia. Specifically, the difference appears in self-ratings rather than observer ratings, indicating differences in how managers in the different areas perceived themselves. Implication? Differences in self ratings may be due to cultural differences in addition to things like personality and instrument type.

The second article is a fascinating one by Saul Fine in which the author analyzed differences in integrity test scores across 27 countries. Fine found two important things: first, there are significant differences in test scores across countries. Second, test results were significantly correlated (r= -.48) with country-level measures of corruption as well as several aspects of Hofstede's cultural dimensions.

Next, an article by De Corte, et al. that describes a method for creating Pareto-optimal selection systems that balance validity, adverse impact, and predictor constraints. This article continues the quest for balancing utility and subgroup differences. A link to the article is here but it wasn't functional at the time I wrote this; hopefully it will be soon.

Next, in an article that SHRM will probably place on their homepage if they haven't already, Lester et al. studied alumni from three U.S. universities to analyze the relationship between attainment of the Professional in Human Resources (PHR) certification offered by SHRM and early career success. Results? Those with a PHR were significantly more likely to obtain a job in HR (versus another field) BUT possession was not associated with starting salary or early career promotions. I'll let you decide if you think it's worth the time (and expense).

If you need another reason to focus on work samples and structured interviews, here ya go. Anderson, et al. provide us with the results of a meta-analysis of applicant reactions to selection instruments. Drawing from data from 17 countries, the authors found results similar to what we've seen in the past: work samples and interviews were most preferred, while honesty testing, personal contacts, and graphology were the least preferred. In the middle (favorably evaluated) were resumes, cognitive tests, references, biodata, and personality inventories.

Fans of biodata and personality testing may find the article by Sisco & Reilly reassuring. Using results from over 700 participants, the authors found that the factor structures of a personality inventory and biodata measure were not significantly impacted by social desirability at the item level. Implication? The measures seemed to hold together and retain at least an aspect of their construct validity even in the face of items that beg inflation.

Speaking of personality tests, Whetzel et al. investigated the linearity of the relationship between the OPQ and job performance. Results? Very little departure from linearity and where present the departure was small. This suggests that utility gains may be obtained across the spectrum of personality test results.

Are you overloading your assessment center raters? Melchers et al. present the results of a study that strongly suggests that if you are using group discussions as an assessment tool, you need to be sensitive to the number of participants that raters are simultaneously observing.

There are other articles in here you may be interested in, including ones on organizational attractiveness, range shrinkage in cognitive ability test scores, and staffing services related to innovation.

Detecting liars is not a skill

One of the most popular pieces of folk wisdom is that some people are better at detecting liars than others. When it comes to selection, some people think they can tell when a candidate is lying about their history or competencies. And if the organization is conducting background checks and/or a polygraph, it becomes particularly important to detect deceptions.

Yet according to a new meta-analysis published in the most recent issue of Psychological Bulletin, we may all be pretty much the same when it comes to lie detection. In the words of the authors:

"Although researchers have suggested that people differ in the ability to detect lies, psychometric analyses of 247 samples reveal that these ability differences are minute."

Where there do appear to be differences is in being able to successfully tell a lie--some people are plain better at it than others.

The article is followed by two commentaries that are critical of this study and a reply by the author.

What about people's overall ability to detect a lie? Check out this study from 2006 by the same authors. Short answer: we're not very good.
