Taxometric Analysis of the Levenson Self-Report Psychopathy Scale

Fifteen HIT cards were administered to 12 Ss before and after paired placebo and alcohol intravenous infusions in a Latin-square cross-over design. Separate sets of cards were used for placebo and alcohol infusions with cards from the A form administered before and the counterpart cards from the B form after each infusion. A significant increase in score in color was noted with the low level of intoxication as compared with placebo infusion. There were no significant differences between placebo and alcohol infusion on other HIT variables. Collateral data from previous alcohol intoxication experiments and other HIT studies suggest that the increase in color may be related to change in affect which accompanies the intoxication.     

Effect of Cheating Experience on Attitudes toward Infidelity

The present study investigated how cheating experience influences perception of others’ infidelity. Using vignette characters, we explored the hypothesis that a participant’s experience cheating on a partner and gender of vignette character moderate gender-differentiated perceptions of infidelity (i.e., men reporting more accepting attitudes toward infidelity than women). Participants (N = 320) were asked a series of questions evaluating both how ‘acceptable’ and ‘forgivable’ was a vignette character’s infidelity. Men and women with prior experience cheating found the cheating vignette character of their same gender significantly more acceptable and forgivable than the unfaithful character of the other gender. Participants who reported no history of infidelity found infidelity as generally unacceptable, regardless of character gender.     

“I Love You, and I Cheated”: Investigating Disclosures of Infidelity to Primary Romantic Partners

The research presented in this article used a quantitative–qualitative mixed design to investigate components of infidelity. Two studies were completed. The first study compared responses from persons (n = 22, 16 women, 6 men) who, in the context of a romantic relationship, disclosed infidelity to their primary partner, with a matched control sample of persons (n = 22, 16 women, 6 men) who did not report infidelity. Study 2 involved in-depth, bibliographic interviews with those persons disclosing infidelity to primary partners. Study 2 explored how persons defined infidelity and the nature of their disclosure. As predicted, results from Study 1 demonstrated clear differences between persons who did and did not report infidelity on measures of sexual permissiveness and intentions to engage in extradyadic activity, but not on other sexological measures. In Study 2, disclosures of infidelity to primary partners were interrogated using principles of interpretive biography. Qualitative analyses revealed that disclosures of infidelity were embedded with multiple meanings, including transformative moments of self-understanding. Results from the current research add depth to researchers’ and clinicians’ understanding of how infidelity is defined and disclosed to partners.     

Actual Versus Perceived Knowledge of Child Development in a Therapeutic Context: A Survey of Therapists

The present study investigates the relationship between therapists' perceived knowledge level in the area of child development and their actual knowledge level, as measured by an assessment instrument developed to measure child development knowledge within a therapeutic setting. Results revealed that respondents felt that they were knowledgable in the area of child development, as well as comfortable working with children in a therapeutic context. However, as a group, the respondents only averaged 68% on the child development assessment scale. Implications of the study's findings, as well as recommendations for clinical training programs and future research, are discussed.     

Caregiver models of self and others, coping, and depression: predictors of depression in children with chronic pain.

In a sample of 59 chronically ill pediatric patients and their maternal caregivers, both child-reported pain and caregiver-reported depression predicted child-reported depression. Results further suggested that the association between pain and depression in children is ameliorated by caregiver coping strategies and that how caregivers cope is a function of their attachment-related representations of the self and others. Caregivers with a negative model of the self were more depressed. and those with a negative model of others were more prone to use avoidant coping strategies, and, in turn, to be more depressed. However, the extent to which caregivers with negative models of self used more avoidant and less approach coping appeared to depend on whether they perceived that others were likely to respond to their needs.     

Taxometric analysis of the Levenson Self-Report Psychopathy scale

Levenson's Self-Report Psychopathy scale (Levenson, Kiehl, & Fitzpatrick, 1995) was administered to 1,972 male and female federal prison inmates, the results of which were subjected to taxometric analysis. We employed 4 taxometric procedures in this study: mean above minus below a cut (Meehl & Yonce, 1994), maximum slope (Grove & Meehl, 1993), maximum eigenvalue (Waller & Meehl, 1998), and latent-mode factor analysis (Waller & Meehl, 1998). The results showed consistent support for a dimensional interpretation of the latent structure of psychopathy, corroborating previous research conducted on the Psychopathy Checklist (e.g., Psychopathy Checklist-Revised; Hare, 2003) and Psychopathic Personality Inventory (Lilienfeld & Andrews, 1996) and denoting that psychopathy is a dimensional construct (degree of psychopathic characteristics) rather than a qualitatively distinct category of behavior (psychopath).     

Survivor Insight: A Study of Family,Friend, and Community Response to Interpersonal Violence

The purpose of this study was to examine the perspectives of survivors of trauma concerning their family, friend, and community responses to their trauma. Using a community-based, participatory action framework, a measure was developed and distributed to 351 randomly drawn survivors of interpersonal violence. The majority of participants indicated that they were never or rarely helped or protected at the time they first experienced the trauma. Several significant correlations were found between participants’ perceptions of their own healing and the responses of people in their lives. Many respondents also indicated that people do not know how to help survivors heal and that the general public does not understand how trauma affects people. The results are discussed within the framework of developing supports for trauma survivors that include trauma-informed family, friends, and community. Questions for further research and implications for professional practice and trauma-informed communities are discussed.     

Toward a hierarchical model of criminal thinking: evidence from item response theory and confirmatory factor analysis

Item response theory (IRT) methods were applied to items from the 80-item Psychological Inventory of Criminal Thinking Styles (PICTS; G. D. Walters, 1995) to determine how well they measure the latent trait of criminal thinking in a group of 2,872 male medium security prison inmates. Preliminary analyses revealed that the 64 PICTS thinking style items, 32 PICTS proactive criminal thinking items, and 24 PICTS reactive criminal thinking items were sufficiently unidimensional to meet the local independence requirements of IRT. The PICTS was fitted to a 2-parameter logistic-graded response IRT model, the results of which showed that the 8 items measuring denial of harm (Sentimentality) displayed weak discrimination (a < 0.5), whereas most of the proactive and reactive items displayed moderate to good discrimination (a > 1.0). Information function analysis revealed that all 3 components of a hierarchical model of criminal thinking--PICTS total scale, PICTS proactive factor, and PICTS reactive factor--displayed greater precision at higher rather than lower levels of the trait dimension. The study findings indicate that items from the PICTS Sentimentality scale do a poor job of measuring general criminal thinking, whereas items from the other 7 PICTS thinking style scales provide their most precise estimates at the upper end of the trait dimension.
