The Three Domains of Disgust Scale: factor structure, psychometric properties, and conceptual limitations

This investigation examined the measurement properties of the Three Domains of Disgust Scale (TDDS). Principal components analysis in Study 1 (n = 206) revealed three factors of Pathogen, Sexual, and Moral Disgust that demonstrated excellent reliability, including test-retest over 12 weeks. Confirmatory factor analyses in Study 2 (n = 406) supported the three factors. Supportive evidence for the validity of the Pathogen and Sexual Disgust subscales was found in Study 1 and Study 2 with strong associations with disgust/contamination and weak associations with negative affect. However, the validity of the Moral Disgust subscale was limited. Study 3 (n = 200) showed that the TDDS subscales differentially related to personality traits. Study 4 (n = 47) provided evidence for the validity of the TDDS subscales in relation to multiple indices of disgust/contamination aversion in a select sample. Study 5 (n = 70) further highlighted limitations of the Moral Disgust subscale given the lack of a theoretically consistent association with moral attitudes. Lastly, Study 6 (n = 178) showed that responses on the Moral Disgust scale were more intense when anger was the response option compared with when disgust was the response option. The implications of these findings for the assessment of disgust are discussed.     

An interpersonal analysis of pathological personality traits in DSM-5

The proposed changes to the personality disorder section of the Diagnostic and statistical manual of mental disorders (5th ed.) places an increased focus on interpersonal impairment as one of the defining features of personality psychopathology. In addition, a proposed trait model has been offered to provide a means of capturing phenotypic variation on the expression of personality disorder. In this study, the authors subject the proposed DSM-5 traits to interpersonal analysis using the inventory of interpersonal problems-circumplex scales via the structural summary method for circumplex data. DSM-5 traits were consistently associated with generalized interpersonal dysfunction suggesting that they are maladaptive in nature, the majority of traits demonstrated discriminant validity with prototypical and differentiated interpersonal problem profiles, and conformed well to a priori hypothesized associations. These results are discussed in the context of the DSM-5 proposal and contemporary interpersonal theory, with a particular focus on potential areas for expansion of the DSM-5 trait model.     

Hungry pigeons make suboptimal choices, less hungry pigeons do not

Hungry animals will often choose suboptimally by being attracted to reliable signals for food that occur infrequently (they gamble) over less reliable signals for food that occur more often. That is, pigeons prefer an option that 50?% of the time provides them with a reliable signal for the appearance of food but 50?% of the time provides them with a reliable signal for the absence of food (overall 50?% reinforcement) over an alternative that always provides them with a signal for the appearance of food 75?% of the time (overall 75?% reinforcement). The pigeons appear to choose impulsively for the possibility of obtaining the reliable signal for reinforcement. There is evidence that greater hunger is associated with greater impulsivity. We tested the hypothesis that if the pigeons were less hungry, they would be less impulsive and, thus, would choose more optimally (i.e., on the basis of the overall probability of reinforcement). We found that hungry pigeons choose the 50?% reinforcement alternative suboptimally but less hungry pigeons prefer the more optimal 75?% reinforcement. Paradoxically, pigeons that needed the food more received less of it. These findings have implications for how level of motivation may also affect human suboptimal choice (e.g., purchase of lottery tickets and playing slot machines).     

The relationship between color–object associations and color preference: Further investigation of ecological valence theory

Ecological valence theory (EVT; Palmer & Schloss, Proceedings of the National Academy of Sciences 107:8877–8882, 2010) proposes that color preferences are due to affective responses to color-associated objects: That is, people generally like colors to the degree that they like the objects associated with those colors. Palmer and Schloss found that the average valence of objects associated with a color, when weighted by how well the objects matched the color (weighted affective valence estimates: WAVE) explained 80% of the variation in preference across colors. Here, we replicated and extended Palmer and Schloss’s investigation to establish whether color–object associations can account for sex differences in color preference and whether the relationship between associated objects and color preference is equally strong for males and females. We found some degree of sex specificity to the WAVEs, but the relationship between WAVE and color preference was significantly stronger for males than for females (74% shared variance for males, 45% for females). Furthermore, analyses identified a significant inverse relationship between the number of objects associated with a color and preference for the color. Participants generally liked colors associated with few objects and disliked colors associated with many objects. For the sample overall and for females alone, this association was not significantly weaker than the association of the WAVE and preference. The success of the WAVE at capturing color preference was partly due to the relationship between the number of associated objects and color preference. The findings identify constraints of EVT in its current form, but they also provide general support for the link between color preference and color–object associations.     

Client Suicide: What Now?

The loss of a client to suicide is a painful personal and professional experience for mental health providers. Whether trainee or experienced professional, the affected clinician often reports feeling overwhelmed and unprepared for the experience of client suicide, together with significant emotional distress and diminished work performance. In this article, we present a brief overview of the literature on the impact of client suicide and ideas for coping with the psychological and professional issues that typically arise. We also provide suggestions for managing the associated practical and administrative tasks, as well as resources for obtaining professional support and guidance in the wake of this tragic event.     

Acceptance and Commitment Therapy for Depression: A Preliminary Randomized Clinical Trial for Unemployed on Long-Term Sick Leave

This preliminary study investigated the feasibility of a brief Acceptance and Commitment Therapy (ACT) in a Swedish sample of unemployed individuals on long-term sick leave due to depression. Participants were randomized to a nonstandardized control condition (N = 16) or to the ACT condition (N = 18) consisting of 1 individual and 5 group sessions. From pretreatment to 18-month follow-up the ACT participants improved significantly on measures of depression, general health, and quality of life compared to participants in the control condition. The conditions did not differ regarding sick leave and employment status at any time point. The results indicate that ACT is a promising treatment for depression. The need for further refinements of future ACT protocols for this population is discussed.     

Midlife Sexuality Among Thai Adults: Adjustment to Aging in the Thai Family Context

The objective of the study is to assess views of age related changes in sexual behavior among married Thai adults age 53–57. Results are viewed in the context of life course theory. In-depth interviews were conducted with 44 Thai adults in Bangkok and the four regions of Thailand. Topics covered include changing sexual behavior with age, adjustment to this change, gender differences in behavior, attitudes toward commercial sex and other non-marital sexual partners, and condom use. Most respondents were aware of this change and saw a decrease in sexual activity and desire more often among women compared to men. At the same time, many respondents viewed sexuality as important to a marriage. Some respondents accepted the decrease in sexual activity and focused more on work, family and temple activities. Thai Buddhism was seen as an important resource for people who were dealing with changes due to aging. Other persons turned to other partners including both commercial and non-commercial partners. The influence of the HIV epidemic that began in the 1990s was seen in concerns about disease transmission with extramarital partners and consequent attitudes toward condom use. The acceptability of extramarital partners in the family and community ranged from acceptance to strong disapproval of extramarital relationships.     

Invisible “Others”: Sexual Health Vulnerabilities of Wives of Men who Have Sex with Men

The recent trend in the feminization of the HIV epidemic poses great risk to women, especially to the wives of men who have sex with men (MSM). The objective of the present study was to explore wives’ responses to their husbands’ sexual orientation as well as the factors that influence their sexual health in India. For this research, 15 wives who were aware of their husbands’ sexual orientation and their husbands were interviewed separately using semi-structured in-depth interviews and focus groups. The study explored the social and cultural structures that create gender inequality, which put women married to MSM at sexual health risk. These factors need to be addressed carefully through existing MSM targeted interventions, without breaching the confidentiality of either partner.     

Determinants of Electoral Support for Anti-Gay Marriage Constitutional Amendments: An Examination of Ballot Issues in California and Florida

Between 1998 and 2006, twenty-seven states amended their constitutions to prohibit same sex marriage. The 2008 elections again saw three states with ballot measures aimed at banning gay marriage. This study examines the determinants of support for those measures in California and Florida, and includes a similar measure placed on the primary election ballot in California in 2000. Support is measured as the county-wide vote in favor of each gay marriage ban. A number of hypotheses are explored that examine the urban/rural nature of each county, as well as the political and demographic characteristics of county residents. It is suggested that states may be best viewed as relatively independent groupings of diverse subcultures, rather than as homogenous populations with a single political culture. The findings reported here indicate that a host of demographic, political and religious differences within each state influence residents’ votes on gay marriage bans.     

A Randomized, Double-Blind, Crossover Comparison of MK-0929 and Placebo in the Treatment of Adults With ADHD

Objective: Preclinical models, receptor localization, and genetic linkage data support the role of D4 receptors in the etiology of ADHD. This proof-of-concept study was designed to evaluate MK-0929, a selective D4 receptor antagonist as treatment for adult ADHD. Method: A randomized, double-blind, placebo-controlled, crossover study was conducted in adults with primary ADHD. The primary end point was changed from baseline in total score on the Adult ADHD Investigator Symptom Rating Scale following a 4-week treatment regimen. Additional measures included Clinical Global Impression-Severity Scale, Hospital Anxiety and Depression Scale, and Brown Attention Deficit Disorder Scale and D4 genotype analysis. Results: No statistically significant treatment differences were found between MK-0929 and placebo in any of the primary or secondary assessments. Conclusion: Results from this study suggest that blockade of the D4 receptor alone is not efficacious in the treatment of adult ADHD.
