Socially desirable responding and the factorial stability of the NEO PI-R

The goal of the present investigation is to compare the factor structure of the revised NEO Personality Inventory (NEO PI-R; P. T. Costa & R. R. McCrae, 1992) in samples of respondents differentially motivated to respond in a socially desirable manner. In the French sample, the authors compared the NEO PI-R structure of job applicants (N=12,631) subgrouped by relative degree of socially desirable responding with that of a normative sample (N=801). In the Belgian sample, the authors compared the NEO PI-R structure in naturally occurring groups, including job applicants (N=3,028), individuals receiving career counseling (N=221), and a normative sample (N=549). Results indicate that the NEO PI-R factor structure remained stable across all samples.     

Socially desirable responding and its elusive effects on the validity of personality assessments

Past studies of socially desirable self-reports on the items of personality measures have found inconsistent effects of the response bias on the measures' predictive validities, with some studies reporting small effects and other studies reporting large effects. Using Monte Carlo methods, we evaluated various models of socially desirable responding by systematically adding predetermined amounts of the bias to the simulated personality trait scores of hypothetical test respondents before computing test-criterion validity correlations. Our study generally supported previous findings that have reported relatively minor decrements in criterion prediction, even with personality scores that were massively infused with desirability bias. Furthermore, the response bias failed to reveal itself as a statistical moderator of test validity or as a suppressor of validity. Large differences between some respondents' obtained test scores and their true trait scores, however, meant that the personality measure's construct validity would be severely compromised and, more specifically, that estimates of those individuals' criterion performance would be grossly in error. Our discussion focuses on reasons for the discrepant results reported in the literature pertaining to the effect of socially desirable responding on criterion validity. More important, we explain why the lack of effects of desirability bias on the usual indicators of validity, moderation, and suppression should not be surprising.     

Socially desirable responding and impression management in the endorsement of love styles.

In 2 experiments, the researcher investigated the social desirability of different love styles (Eros, Ludus, Storge, Pragma, Mania, and Agape). In Experiment 1, the Marlowe-Crowne measure of social desirability (D. P. Crowne & D. Marlowe, 1960) was correlated negatively with possessive, dependent (Mania) love styles in both men and women. In men, social desirability was correlated positively with romantic, passionate love (Eros) and game-playing love (Ludus), but negatively with all-giving, selfless love (Agape). In women, social desirability was correlated positively with Agape, but negatively with Ludus. In Experiment 2, the researcher replicated these findings using an impression management manipulation (good, bad, and honest responding). The gender differences in social desirability of different love styles are explained in terms of traditional and nontraditional gender role socialization.     

Social desirability and self-reports: testing models of socially desirable responding

The present research investigated the cognitive processes involved in responding to self-report items under varying conditions of social desirability. Participants in three experiments judged the extent to which a set of items (personality traits in Experiments 1 and 2; behaviors in Experiment 3) described them under instructions that either increased or decreased concerns with social desirability. Under most conditions, instructions that produced the greatest concern with social desirability resulted in the longest response times. This finding is consistent with the view that social desirability operates as an editing process; participants retrieve the requested information and then evaluate it before responding. There was also some evidence for individual differences in social desirability; participants scoring high on the trait of self-deception were generally faster at making these judgments than were participants scoring low on self-deception.     

Impact of elaboration on socially desirable responding and the validity of biodata measures

The current study investigated the impact of requiring respondents to elaborate on their answers to a biodata measure on mean scores, the validity of the biodata item composites, subgroup mean differences, and correlations with social desirability. Results of this study indicate that elaborated responses result in scores that are much lower than nonelaborated responses to the same items by an independent sample. Despite the lower mean score on elaborated items, it does not appear that elaboration affects the size of the correlation between social desirability and responses to biodata items or that it affects criterion-related validity or subgroup mean differences in a practically significant way.     

Racial differences in socially desirable responding in selection contexts: magnitude and consequences

Two studies were conducted to examine the magnitude and consequences of racial differences on social desirability (SD) scales. Study 1 included 1,063 job applicants, and Study 2 included 3 sets of incumbents (total N = 534). In both studies, participants were administered several personality measures and an SD scale. Across all samples, Whites scored lower on the SD scale than Blacks (average d = .37), Hispanics (average d = .47), and Asians (average d = 1.04), but these differences were not observed on the personality scales. The consequence of differences in socially desirable responding (SDR) is that fewer minority group members would be selected if SD scales were used to derive cut scores to eliminate individuals from the applicant pool or if the scales were used to correct personality test scores for SDR. However, applying the SD correction did not affect the validity of the personality test for any of the racial groups. Overall, our findings suggest that researchers and practitioners should consider the use of SD scales very carefully, as their use may have unintended consequences. These studies also demonstrate a need to closely examine the construct validity of SD measures across diverse groups.     

Comparing continuous and dichotomous scoring of the balanced inventory of desirable responding

The Balanced Inventory of Desirable Responding (BIDR; Paulhus, 1994) is a widely used instrument to measure the 2 components of social desirability: self-deceptive enhancement and impression management. With respect to scoring of the BIDR, Paulhus (1994) authorized 2 methods, namely continuous scoring (all answers on the continuous answer scale are counted) and dichotomous scoring (only extreme answers are counted). In this article, we report 3 studies with student samples, and continuous and dichotomous scoring of BIDR subscales are compared with respect to reliability, convergent validity, sensitivity to instructional variations, and correlations with personality. Across studies, the scores from continuous scoring (continuous scores) showed higher Cronbach's alphas than those from dichotomous scoring (dichotomous scores). Moreover, continuous scores showed higher convergent correlations with other measures of social desirability and more consistent effects with self-presentation instructions (fake-good vs. fake-bad instructions). Finally, continuous self-deceptive enhancement scores showed higher correlations with those traits of the Five-factor model for which substantial correlations were expected (i.e., Neuroticism, Extraversion, and Conscientiousness). Consequently, these findings indicate that continuous scoring may be preferable to dichotomous scoring when assessing socially desirable responding with the BIDR.     

Psychological determinants of health and performance: the tangled web of desirable and undesirable characteristics.

Correlations were determined for male (n = 225) and female (n = 242) college students between sets of undesirable personality traits (anxiety, stress reactivity, anger, and alienation) and desirable personality traits (instrumentality, achievement strivings, and optimism measured by the Scheier-Carver [1987] Life Orientation Test), and a series of outcome variables related to health (self-reported health complaints and health maintenance behaviors and beliefs) and academic performance (academic expectations and actual grade point average). Significant correlations were found between many of the personality variables and the outcome variables. However, partial correlations revealed different relationships for the various criteria. With other variables held constant, health complaints were related to several undesirable characteristics, whereas health maintenance behaviors and beliefs were related to several desirable attributes. Only achievement strivings made an independent contribution in both sexes to the 2 measures of academic performance. The theoretical and methodological wisdom of using measures of multiple personality constructs and outcome variables is discussed.     

MMPI-2 L + K and L + K - F indexes of underreporting: normative and desirable responding

Norms based on the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) normative sample are provided for the L + K and L + K - F indexes of underreporting and defensiveness. Index scores produced by consistently desirable responding, which was guided by desirability ratings of the MMPI-2 items, also are provided and compared with scores produced by underreporting in other studies. The indexes correlate highly with other measures of underreporting in both normative and clinical samples. The L and K scales assess different types of underreporting and should be interpreted separately as well as in combination. The L scale can be elevated by undesirable responding or random responding in addition to desirable responding.     

Mechanisms underlying retarded emergence of conditioned responding following inhibitory training: evidence for the comparator hypothesis

The comparator hypothesis posits that conditioned responding is determined by a comparison at the time of testing between the associative strengths of the conditioned stimulus (CS) and stimuli proximal to the CS at the time of conditioning. The hypothesis treats all associations as being excitatory and treats conditioned inhibition as the behavioral consequence of a CS that is less excitatory than its comparator stimuli. Conditioned lick suppression by rats was used to differentiate four possible sources of retarded responding to an inhibitory CS. These include habituation to the unconditioned stimulus (US), latent inhibition to the CS, blocking of the CS-US association by the conditioning context, and enhanced excitatory associations to the comparator stimuli. Prior research has demonstrated the first three phenomena. Therefore, we employed parameters expected to highlight the fourth one--the comparator process. In Experiment 1, our negative contingency training was shown to produce a conditioned inhibitor that passed inhibitory summation and retardation tests. In Experiment 2 we found transfer of retardation from an inhibitory CS to a novel stimulus when the location where retardation-test training occurred was excitatory, which is indicative of contextual blocking and/or comparator effects. In Experiment 3, extinction of the conditioning context was found to attenuate retardation regardless of whether extinction occurred before or after the CS-US pairings of the retardation test. This indicates that much of the present retardation was due to the comparator process rather than to contextual blocking. Experiment 4 demonstrated that habituation to the US did not contribute to retardation in the present case. Collectively, these studies suggest that retardation following inhibitory training can be explained without recourse to any of the traditional mechanisms of conditioned inhibition.     

Rats learn the relationship between responding and environmental events: An expansion of the learned helplessness hypothesis

Previous research has shown that preexposure to inescapable shock interferes with subsequent acquisition of escape responding, while pretraining with escapable shock facilitates subsequent acquisition of a different escape response. It has also been demonstrated that interference and facilitation persist when the aversive event is changed between the two phases of training. The present experiment extended these findings, showing generalized learning from an appetitive to an aversive situation. Six groups of rats received the following treatment in the presence of discriminative stimuli: One group was trained to nose press for food, a second to chain pull for food, and a third to chain pull to escape or avoid shock. Two groups received either signalled free food or inescapable shock, and a naive control group received no pretreatment. All groups were then tested in a nose-press escape-avoidance situation. The three groups with prior response training acquired responding most rapidly, and at the same rate. The naive controls acquired responding slowly, and the two groups with response-independent histories did not acquire responding during the 5 days of training. It was concluded that rats learn the relationship between responding and environmental events and that such learning strongly influences subsequent learning.     

The structure of values: Conceptions of the desirable

The study aim was to define currently discernible conceptions of the desirable. An inventory of personal value statements was constructed, administered to two large samples, and factor analyzed. Twelve first order and four higher-level dimensions were identified in both samples. An hypothesis that liberal-conservative attitudes were predictable to a high degree from the authoritarian value orientation was tested and confirmed. Each of the four higher level dimensions was interpretable as a specific ethic or organized set of rules that guide conduct. The four ethics or value dimensions were labeled Acceptance of Authority, Work Ethic, Humanistic Orientation, and Hedonistic Orientation.     

Studies on responding under fixed-interval schedules of reinforcement: the effects on the pattern of responding of changes in requirements at reinforcement

In pigeons responding under a 180-sec fixed-interval schedule of reinforcement, the frequency distribution of the duration of the final interresponse time before the reinforcer was compared with the distribution of the preceding two interresponse times. The results confirmed qualitatively and quantitatively the expected preferential reinforcement of longer interreinforcement times under fixed-interval reinforcement. Requirements at reinforcement were then changed to eliminate the preferential reinforcement of longer interresponse times. Local patterns and mean rate of responding could change, without the characteristic fixed-interval pattern of increasing responding through the interval (scalloping) being much affected. It is concluded that this characteristic pattern of fixed-interval responding does not depend crucially on effects of the reinforcer at the moment of reinforcement, but rather to effects extending over much longer periods of time than just the last interresponse time.     

Trauma: the seductive hypothesis

In much of contemporary culture, "trauma" signifies not so much terrible experience as a particular context for understanding and responding to a terrible experience. In therapy, in the media, and in international interventions, the traumatized are seen not simply as people who suffer and so are deserving of concern and aid; they are seen also as people who suffer for us, who are given special dispensation. They are treated with awe if they tell a certain kind of trauma story, and are ignored or vilified if they tell another. Trauma has become not simply a story of pain and its treatment, but a host of sub-stories involving the commodification of altruism, the justification of violence and revenge, the entry point into "true experience," and the place where voyeurism and witnessing intersect. Trauma is today the stuff not only of suffering but of fantasy. Historically, trauma theory and treatment have shown a tension, exemplified in the writings of Freud and Janet, between those who view trauma as formative and those who view it as exceptional. The latter view, that trauma confers exceptional status deserving of special privilege, has gained ground in recent years and has helped to shape the way charitable dollars are distributed, how the traumatized are presented in the media, how governments justify and carry out international responses to trauma, and how therapists attend to their traumatized patients. This response to trauma reflects an underlying, unarticulated belief system derived from narcissism; indeed, trauma has increasingly become the venue, in society and in treatment, where narcissism is permitted to prevail.     

Operant and nonoperant vocal responding in the mynah: Complex schedule control and deprivation-induced responding

Several recent studies have been concerned with operant responses that are also affected by nonoperant factors, (e.g., biological constraints, innate behavior patterns, respondent processes). The major reason for studying mynah vocal responding concerned the special relation of avian vocalizations to nonoperant emotional and reflexive systems. The research strategy was to evaluate operant and nonoperant control by comparing the schedule control obtained with the vocal response to that characteristic of the motor responses of other animals. We selected single, multiple, and chain schedules that ordinarily produce disparate response rates at predictable times. In multiple schedules with one component where vocal responding (“Awk”) was reinforced with food (fixed-ratio or fixed-interval schedule) and one where the absence of vocal responding was reinforced (differential reinforcement of other behavior), response rates never exceeded 15 responses per minute, but clear schedule differences developed in response rate and pause time. Nonoperant vocal responding was evident when responding endured across 50 extinction sessions at 25% to 40% of the rate during reinforcement. The “enduring extinction responding” was largely deprivation induced, because the operant-level of naive mynahs under food deprivation was comparable in magnitude, but without deprivation the operant level was much lower. Food deprivation can induce vocal responding, but the relatively precise schedule control indicated that operant contingencies predominate when they are introduced.     

Detection of random responding on the MMPI-A

We examined random responding on the MMPI-A in 106 adolescents from the general population. Participants were asked to report on the frequency, location, and reasons for any random responses occurring during a standard administration of the MMPI-A. Relationships between self-reported random responding and validity indices (F1, F2, F, and Variable Response Inconsistency [VRIN] scale) were examined. In addition, each participant was randomly assigned to 1 of 5 groups, with each group completing an assigned portion (0, 25%, 50%, 75%, or 100%) of an MMPI-A answer sheet without access to the test booklet, and the utility of the validity scales in discriminating standard protocols from all or partially random protocols was investigated. Most adolescents acknowledged one or more random responses correlated significantly with F but not VRIN. Validity scales were sensitive to all or partially random protocols, and produced high classification rates when discriminating among groups.     

Identification of random responding on the MMPI-A

Although substantial research literature on the effects of random responding on the MMPI-2 exists, there is very limited data available on this issue with the MMPI-A. The purpose of this study was to evaluate the utility of selected MMPI-A validity scales in detecting differences in response patterns between protocols produced by 354 adolescents assessed in clinical settings and a group of 354 randomly produced MMPI-A protocols. Results indicate that MMPI-A validity and basic clinical scales differ significantly between random and clinical groups and that MMPI-A validity Scales F, F1, F2, and VRIN appear to be most useful in correctly identifying protocols from actual clinical participants versus randomly generated response patterns. Findings are discussed in terms of the dramatic effects of the sample base rate for random responding on overall classification accuracy results. Furthermore, it was noted that the optimal cutting scores for MMPI-A Scales F, F1, F2, and VRIN were largely consistent with interpretive recommendations found in the test manual (Butcher et al., 1992) when the relative frequency of random response protocols to clinical protocols was evaluated at a ratio of 1:10. Finally, future recommendations for evaluation of the F1-F2 difference score and the TRIN scale are offered in terms of the most relevant research designs to evaluate these measures.     

Dyslexia: the articulatory hypothesis revisited

Articulatory disorders have been associated with developmental phonological dyslexia in the literature. However, very few information is available about the articulatory movements involved in speech production in dyslexic children. This study uses aerodynamic/acoustic data to explore how dyslexic children produce bilabial stops in French (/b, p/) within a sentence where they occurred in two positions and in three vowel environments. Average durations of articulatory closure and release were calculated in 10 phonological dyslexic children and two groups of age-matched and reading age-matched controls. Moreover, deviation from a standard pronunciation of the same material was evaluated separately by blind examiners. Our results reveal differences in the timing of the articulatory movements between dyslexics and normal controls, as well as more deviations from the target consonant for the dyslexics than for the controls. These observations are consistent with recent findings pointing to a general deficit in fine motor control in dyslexia.
