Deceptiveness on the PAI: a study of naïve faking with psychiatric inpatients

In this study, we sought to explore the diagnostic accuracy of the Personality Assessment Inventory (PAI; Morey, 1991) Validity scales (Negative Impression Management [NIM] and Positive Impression Management [PIM]) and indexes (Malingering index, Defensiveness index [DEF]; Morey, 1993, 1996; Cashel Discriminant Function; Cashel, Rogers, Sewell, & Martin-Cannici, 1995; and Rogers Discriminant Function [RDF]; Rogers, Sewell, Morey, & Ustad, 1996) to identify differences in profiles completed by psychiatric inpatients under standardized instructions (Time 1) and after random assignment (Time 2) to a fake good (n=21), fake bad (n=20), or retest (n=21) scenario. Repeated measures analysis of variance revealed a significant interaction effect. Whereas the retest group did not show any significant changes on the PAI variables from Time 1 to Time 2, both faking groups showed changes in expected directions. Discriminant function analyses revealed that NIM, RDF, and lower scores on DEF best differentiated between the faking bad and retest groups. PIM was the only nonredundant significant score discriminating the faking good and retest groups. Cutoffs for these scales and indexes established in prior research were supported using diagnostic efficiency statistics. Results suggest that NIM and RDF in faking bad scenarios and PIM in faking good scenarios are most sensitive to unsophisticated attempts to dissimulate by inpatient psychiatric patients.     

Optimism, stress, life satisfaction, and job burnout in restaurant managers

Researchers have suggested that dispositional optimism is related to both stress and stress outcomes. However, the nature of this relationship has not fully been explained. The authors contributed to a better understanding of this relationship by evaluating dispositional optimism, stress, overall life satisfaction, and job burnout in a sample of restaurant managers. Results indicated that stress and job burnout were significantly related; however, their relationship was not moderated by dispositional optimism, as would be suggested by the results of past research. The diminished personal accomplishment dimension of job burnout mediated the relationship between optimism and life satisfaction. Also, stress significantly impacted perceptions of diminished personal accomplishment and life satisfaction.     

50% off or buy one get one free? Frame preference as a function of consumable nature in dairy products

Previous studies on how framing differentially affects consumer perceptions of value from equivalent deals indicate that perceptions of deal value from price-saving versus extra-product promotions are moderated by the stock-up characteristic of the category. In this study, the authors explored the relationship between stock-up characteristic and frame preference and the influence of the consumable nature of goods on frame preference. An experiment involving 223 student participants showed that consumable nature, but not stock-up characteristic, affected frame preference. The authors discuss the implications of this finding for the study of information framing and how it impacts consumer judgment and decision making.     

Toward using confidence intervals to compare correlations

Confidence intervals are widely accepted as a preferred way to present study results. They encompass significance tests and provide an estimate of the magnitude of the effect. However, comparisons of correlations still rely heavily on significance testing. The persistence of this practice is caused primarily by the lack of simple yet accurate procedures that can maintain coverage at the nominal level in a nonlopsided manner. The purpose of this article is to present a general approach to constructing approximate confidence intervals for differences between (a) 2 independent correlations, (b) 2 overlapping correlations, (c) 2 nonoverlapping correlations, and (d) 2 independent R2s. The distinctive feature of this approach is its acknowledgment of the asymmetry of sampling distributions for single correlations. This approach requires only the availability of confidence limits for the separate correlations and, for correlated correlations, a method for taking into account the dependency between correlations. These closed-form procedures are shown by simulation studies to provide very satisfactory results in small to moderate sample sizes. The proposed approach is illustrated with worked examples.

Appraisal Underpinnings of Affective Chronometry: The Role of Appraisals in Emotion Habituation

ABSTRACT In light of the lack of studies examining the cognitive components of affective chronometry, this research examined the appraisals associated with emotion habituation, using anger as the emotion of focus. Anger and its appraisals were assessed repeatedly over a day in the participants' naturalistic contexts. The trajectory of decline in anger over time after its first appearance was found to be a function of chronic coping styles. More importantly, the trajectories of anger-related appraisals generally corresponded to that of anger and were also moderated by coping styles in ways consistent with the moderating effects of coping styles on anger. Implications of these results for affective chronometry research and for appraisal research are discussed.     

Gender, Race and Morality in the Virtual World and Its Relationship to Morality in the Real World

This research examines children’s beliefs about moral behavior in the virtual world and the real world. Participants were 515 children, average age 12 years old. One-third were African American and two-thirds were Caucasian American. Children completed surveys mailed to their homes which included questions about the acceptability of morally questionable virtual behaviors. Findings indicated: (1) gender and race differences in the acceptability of morally questionable behaviors in the virtual world; (2) moral behavior and moral attitudes in the real world predicted the acceptability of morally questionable behaviors in the virtual world; and (3) the frequency of IT use predicted the acceptability of morally questionable behaviors in the virtual world. Implications for children’s IT education are discussed.     

The Relationship Between Caregiver Capacity and Intensive Community Treatment for Children with a Mental Health Crisis

We studied 9,220 children referred to a comprehensive mental health crisis stabilization program to examine the impact of caregiver capacity on crisis worker decisions to refer children for intensive community-based treatment as opposed to inpatient psychiatric hospitalization. Due to the different role of caregivers in the child welfare system, analyses were stratified by state custody status. Among both groups, there was a significant inverse association between child mental health need and referral to intensive community-based treatment. For children not in state custody with low mental health need, there was no difference in the likelihood of referral to intensive community-based treatment across levels of caregiver capacity. However, for children not in state custody with medium and high mental health needs, those whose caregivers were deficient or severely deficient were significantly more likely to be referred for intensive community-based treatment than were those who had capable caregivers. Multivariate analyses demonstrated similar results after controlling for potential confounding variables and confirmed that caregiver capacity contributes significantly to the logistic model’s classification accuracy. Results suggest further investigation of the impact of caregiver capacity on mental health crisis worker referral decisions is needed.     

Linda问题:"齐当别"抉择模型的解释

大量有关人类归因判断的研究表明,人类经常违反理性概率公理.Tversky和Kahneman(1983)使用Linda问题等特定场景的研究发现,人们系统性地表现出违反理性推断标准,判断合取事件发生概率大于其组成事件发生概率,称之为合取谬误,并用人们使用代表性启发式判断概率来解释该现象产生的原因.然而使用启发式观点对合取谬误现象进行解释过于模糊不清.该文首先介绍了合取谬误现象及其解释模型,然后应用Li(1994,2004)提出的不确定情形下决策理论--"齐当别"抉择模型对Linda问题中合取谬误产生的原因进行了新的解释.
