Psychopaths have long been characterized as having a remarkable disregard for the truth, to the extent that deceit is often regarded as a defining characteristic of the syndrome. Scholars described heightened concerns about how psychopaths’ deceitful and manipulative nature could significantly obstruct evaluations of psychopathy. The accurate evaluation of psychopathy is very important in forensic and correctional settings, and in such issues as risk assessment or dangerousness. Although the PCL-R is considered the quasi-gold standard when it comes to evaluating psychopathy, self-report measures have become more widely available and researched. Very few studies specifically evaluated response styles and self-report psychopathy measures despite the significant concerns regarding psychopathy and deception. The current study evaluated the ability of inmates with different levels of psychopathy to successfully engage in positive impression management on the SRP-4, LSRP, and PPI-R. Utilizing a repeated-measures, within-subjects design, 78 male inmates completed the study under genuine and simulation conditions. Overall, inmates were able to significantly lower their scores on all three self-report measures and achieved scores equivalent to and even lower than college and community samples. Inmates with higher levels of psychopathy were able to achieve larger decreases in scores on the PPI-R and on several scales for each measure. Another key finding was the identification of promising PPI-R Virtuous Responding Scale cut scores that can be utilized within forensic populations. Results indicate self-report measures should not be used to replace the PCL-R or comprehensive assessment of psychopathy in forensic evaluations; however, they do provide additional useful information and may be beneficial in other clinical settings.

In a study investigating the ability of subjects and their close friends or relatives (close-others) to recognize subject personality test results under conditions which controlled for the Barnum effect, 64 male and female undergraduate psychology students were administered the California Psychological Inventory (CPI). Each subject later attempted to choose his or her own unidentified CPI profile from among three, and a close-other of the subject independently made the same selection. It was found that 57.81% of subjects and 45.31% of close others were able to correctly identify subject profiles; these results were significant at the .0001 and .05 levels respectively. The 53.12% rate of agreement between subjects and close-others in profile selection also proved significant, p < .001. In contrast with results from a previous study (Carlson, 1985), it was found that subject self-perception and CPI description correspond to a highly significant ·degree.

Because of the outcomes associated with employee turnover, few areas have been researched as extensively in the field of Industrial/Organizational Psychology (Cotton&Tuttle, 1986). Correlates and consequences of employee turnover have been widely examined, though less expansive research has been dedicated to identifying (and potentially screening) turnover prone candidates. To address this concern, the comparative utility of three personality measures for predicting voluntary turnover in law enforcement was assessed. Self-report predictor measures consisted of the Minnesota Multiphasic Personality Inventory-2, the most widely used instrument in this industry, and the Personality Research Form-E. The implicit personality measure for this investigation was the Conditional Reasoning Test for Aggression (James, 1998). In line with previous research (e.g., Hough, 1998), self-report job applicant scores indicated a defensive or self-presentation bias, whereas the CRT-A did not. Normative and comparative data for all predictor measures are presented to further knowledge for the researcher and practitioner. The importance of context, in this case the influence of the economy on attrition rates, is also discussed.

The effect of Socially Desirable Responding (SDR) and response distortion on personality and selection measures has been debated for decades (Edwards, 1957b; Messick&Jackson, 1961; Morgeson et al., 2007, Ones, Viswesvaran,&Reiss, 1996). One area of this broad topic that has received less attention over the years has been the effectiveness of the scales used to measure SDR when evidence of potential response distortion is present. Using a MANOVA, this study found significant differences between job candidate and incumbent responses on the scales of the 16PF (Cattell&Cattell, 1995), which can be indicative of SDR (Rosse et al., 1998). However, no difference between the groups was found on the Impression Management scale used to measure SDR. Differences based on the job function of the respondents were also explored.

The Neuropsychological Symptom Inventory (NSI; Rattan, Dean, & Rattan, 1989), a self report measure of psychiatric and neurological symptoms, was revised to be presented in an electronic format. This revised instrument, the Neuropsychological Symptom Scale (Dean, 2010), was administered to 1,141 adult volunteers from a medium-sized Midwestern university. The collected data was subjected to exploratory factor analysis which suggested three primary factors related to emotional, cognitive, and somatosensory functioning. The items on the NSS were then organized into three subscales reflecting these areas of functioning. A fourth experimental subscale was also created to facilitate the collection of data on items that did not load on any of the three primary subscales. Item Response Theory (IRT) analysis and Classical Test Theory (CTT) approaches were then applied and compared as means of developing standard scores on the three primary subscales of the NSS. The results of these analyses are provided along with recommendations related to the further development of the NSS as an assessment tool. / Department of Educational Psychology

This study compared the differential influence of reframing, self-control, and neutral counselor interventions on high and low trait-anxious subjects' self -descriptions as measured by the Adjective Check List. Reframing was predicted to be superior to self-control and neutral interventions in eliciting more favorable self-descriptions. An interaction was also predicted between counselor intervention and trait anxiety such that, in the reframing condition, low trait-anxious subjects would describe themselves more positively than high trait-anxious subjects.

Despite its convenience, the process of self-report in personality testing can be impacted by a variety of cognitive and perceptual biases. One bias that violates local independence, a core criterion of modern test theory, is the order effect. In this bias, characteristics of an item response are impacted not only by the content of the current item but also the accumulated exposure to previous, similar-content items. This bias is manifested as increasingly stable item responses for items that appear later in a test. Previous investigations of this effect have been rooted in classical test theory (CTT) and have consistently found that item reliabilities, or corrected item-total score correlations, increase with the item's serial position in the test. The purpose of the current study was to more rigorously examine order effects via item response theory (IRT). To this end, the FACETS modeling approach (Linacre, 1989) was combined with the Generalized Partial Credit model (GPCM; Muraki, 1992) to produce a new model, the Generalized Partial Credit FACETS model (GPCFM). Serial position of an item serves as a facet that contributes to the item response, not only via its impact on an item's location on the latent trait continuum, but also its discrimination. Thus, the GPCFM differs from previous generalizations of the FACETS model (Wang&Liu, 2007) in that the item discrimination parameter is modified to include a serial position effect. This parameter is important because it reflects the extent to which the purported underlying trait is represented in an item score. Two sets of analyses were conducted. First, a simulation study demonstrated effective parameter recovery, though measurements of error were impacted by sample size for all parameters, test length for trait level estimates, and the size of the order effect for trait level estimates, and an interaction between sample size and test length for item discrimination. Secondly, with respect to real self-report personality data, the GPCFM demonstrated good fit as well as superior fit relative to competing, nested models while also identifying order effects in some traits, particularly Neuroticism, Openness, and Agreeableness.

Indiana University-Purdue University Indianapolis (IUPUI) / Ecological momentary assessment (EMA) has been asserted by proponents of the technique as being superior to standard paper-and-pencil measurements in terms of the reliability and validity of the information obtained; however, this claim has not yet been fully evaluated in the literature. Accordingly, the purpose of this study was to evaluate one aspect of this assertion by comparing the utility of EMA and retrospective measures of depressive symptoms in predicting health-relevant biological and behavioral outcomes. It was hypothesized that (1) the EMA measure will have better predictive utility when examining objective sleep quality (a biological outcome), and that (2) the retrospective measure will have better predictive utility when examining blood donation intention (a behavioral outcome). Ninety-six undergraduate females participated in this 2-week study. Depressive symptoms were measured momentarily and retrospectively using the Center for Epidemiological Studies-Depression Scale (CES-D). The biological outcome was assessed by actigraphy, whereas the behavioral outcome was measured via a self-report questionnaire. Unfortunately, it was not possible to fully test these hypotheses due to the failure to observe relationships between the predictor variables and the outcomes. The reported results, although limited, did not provide support for the hypotheses. Supplemental analyses revealed a moderate to high amount of shared variance between the EMA and retrospective measures, a similar extent of random error in both measures, and potentially a greater degree of systematic error in the retrospective measure. Due to the paucity of literature examining the claim of superior reliability and validity of EMA versus retrospective measures, as well as the failure of the current study to evaluate this assertion sufficiently, it appears that this claim remains unfounded. Therefore, suggestions for future research are provided.
