Dementia has a categorical, not dimensional, latent structure

Recently, Walters ("Dementia: Continuum or distinct entity?", Psychology and Aging, 2010, 25, 534-544) published a taxometric study suggesting a dimensional latent structure for the construct of dementia. However, because that study did not conceptualize dementia according to accepted conventions (i.e., there were no measures of cognitive change or independent functioning), its results may represent a false negative error caused by insufficient content coverage. We replicated Walters, and we used the same taxometric methods and the same data source-but with indicators of cognitive change and functional independence. Our results support a categorical interpretation of dementia; whereas Walters' results suggest that cognitive ability, rather than dementia, is dimensional in nature.

Disengagement and Engagement Coping with HIV/AIDS Stigma and Psychological Well-Being of People with HIV/AIDS

The stigma associated with HIV/AIDS poses a psychological challenge to people living with HIV/AIDS. We hypothesized that that the consequences of stigma-related stressors on psychological well-being would depend on how people cope with the stress of HIV/AIDS stigma. Two hundred participants with HIV/AIDS completed a self-report measure of enacted stigma and felt stigma, a measure of how they coped with HIV/AIDS stigma, and measures of depression and anxiety, and self-esteem. In general, increases in felt stigma (concerns with public attitudes, negative self-image, and disclosure concerns) coupled with how participants reported coping with stigma (by disengaging from or engaging with the stigma stressor) predicted self-reported depression, anxiety, and self-esteem. Increases in felt stigma were associated with increases in anxiety and depression among participants who reported relatively high levels of disengagement coping compared to participants who reported relatively low levels of disengagement coping. Increases in felt stigma were associated with decreased self-esteem, but this association was attenuated among participants who reported relatively high levels of engagement control coping. The data also suggested a trend that increases in enacted stigma predicted increases in anxiety, but not depression, among participants who reported using more disengagement coping. Mental health professionals working with people who are HIV positive should consider how their clients cope with HIV/AIDS stigma and consider tailoring current therapies to address the relationship between stigma, coping, and psychological well-being.     

Psychopathic traits and externalizing behaviors: a comparison of self- and informant reports in the statistical prediction of externalizing behaviors

It has long been assumed that features associated with psychopathy, such as a lack of insight and deceitfulness, may compromise the utility of self-report measures, particularly for understanding the relations between these traits and important outcomes (e.g., offending). Unfortunately, little research has explicitly examined the relations between self- and informant reports of psychopathy and their relations to these outcomes. The current study examined the incremental validity of self- and informant reports of psychopathic traits, assessed with 3 validated psychopathy measures, in the statistical prediction of externalizing behaviors (EBs). To reduce shared method variance, self- and informant reports of EBs (i.e., substance use, antisocial behavior, gambling, and intimate partner violence) were examined separately. Results indicate that both self- and informant reports of psychopathy are related to EBs and provide some degree of incremental validity, although self-reported psychopathy scores proved slightly more useful than other-reported psychopathy scores. These findings suggest that, in nonforensic settings, psychopathy data derived from both self- and other-reported psychopathy measures have utility in understanding the relations between psychopathic traits and EBs.     

Barriers to and Motivations for Physician Referral of Patients to Cancer Genetics Clinics

Although it is well known that under-referral of colon cancer patients to cancer genetics clinics is a chronic problem, no study has yet examined why physicians may be ordering testing independently rather than referring patients to cancer genetics clinics. The current study explored variables which may impact a physician’s preference for ordering testing independently or referring patients to outside cancer genetics experts. An online questionnaire, distributed to the membership of the American College of Gastroenterology and the American Society of Colorectal Surgeons, yielded responses from 298 physicians. Motivations to refer to cancer genetics clinics rather than order testing independently included fear of genetic discrimination and a belief that patients benefit from genetic counseling about the risks, benefits and consequences of testing. These results suggest that in order to increase referrals, genetic counselors must educate physicians about the unique benefits patients receive from participating in genetic counseling.     

Is the Narcissistic Personality Inventory still relevant? A test of independent grandiosity and entitlement scales in the assessment of narcissism

Some scholars have called for the replacement of the Narcissistic Personality Inventory (NPI) with more narrow scales measuring grandiosity and entitlement instead. In the current study, the authors examined the relations among the NPI and measures of grandiosity and entitlement, as well as in relation to a measure of the Five-Factor Model (FFM). The NPI manifested significant correlations with the alternative scales of entitlement and grandiosity and relatively similar patterns of correlations with the FFM traits. Of note, the NPI manifested significant incremental validity in the prediction of several FFM traits that are central to the conceptualization of narcissism. These findings suggest that some caution must be used before assuming that these lower-order scales can be used to replace the NPI in the assessment of narcissism.     

Recruiting and Retaining High-Risk Adolescents into Family-Based HIV Prevention Intervention Research

The purpose of this study was to examine the effectiveness of evidence-based recruitment and retention strategies for a longitudinal, family-based HIV prevention intervention study targeting adolescents in psychiatric care by (1) determining consent rate (recruitment), rate of participation at the first intervention session (retention), and follow-up attendance rate (retention); and (2) examining socio-demographic factors, family-level processes, sexual risk-related indices, and intervention factors (i.e., treatment arm) associated with study retention. Only one-third of the families contacted ultimately enrolled in the study. 81% of those enrolled participated in the workshop and 72% attended the booster sessions with no significant differences between families on any variable based on attendance. Retention over 1?year was 85% and did not differ by treatment arm. Strategies employed were successful at retaining families once they were enrolled. Findings highlight barriers to enrollment for adolescents in psychiatric care and suggest that it may be critical to integrate HIV prevention programs within community-based mental health services in order to counteract recruitment challenges.     

Too dog tired to avoid danger: Self-control depletion in canines increases behavioral approach toward an aggressive threat

This study investigated whether initial self-control exertion by dogs would affect behavioral approach toward an aggressive threat. Dogs were initially required to exert self-control (sit still for 10 min) or not (caged for 10 min) before they were walked into a room in which a barking, growling dog was caged. Subject dogs spent 4 min in this room but were free to choose where in the room they spent their time. Approaching the unfamiliar conspecific was the predisposed response, but it was also the riskier choice (Lindsay, 2005). We found that following the exertion of self-control (in comparison with the control condition), dogs spent greater time in proximity to the aggressor. This pattern of behavior suggests that initial self-control exertion results in riskier and more impulsive decision making by dogs.     

Stalking: Patterns,motives, and intervention strategies

Stalking is generally defined as an intentional pattern of repeated intrusive and intimidating behaviors toward a specific person that causes the target to feel harassed, threatened, and fearful, or that a reasonable person would regard as being so. Motivations for stalking include a delusional belief in romantic destiny, a desire to reclaim a prior relationship, a sadistic urge to torment the victim, or a psychotic overidentification with the victim and the desire to replace him or her. Stalkers may carry a variety of diagnostic labels, including psychotic disorders, delusional disorders, or cluster-B personality disorders, and are generally refractive to conventional psychological treatments. Risk factors for violence in a stalking scenario include a prior intimate relationship, the stalker's feeling of being rejected or humiliated, and generic risk factors for violence such as low educational level and substance abuse. Cyberstalking can be as distressing, if not more so, to victims as physical stalking due to the concealment and anonymity afforded by electronic communication. Victims may adopt varying strategies for dealing with stalkers, such as avoiding, confronting, seeking third party assistance, and accessing the legal system. Threat management specialists have offered certain recommendations that can make it easier for a victim to deter and discourage a stalker.     

‘The third person in the room’: Recording the counselling interview for the purpose of counsellor training – barrier to relationship building or effective tool for professional development?

Objective: Audio and videotape interview recording for training and supervision in counsellor education is commonplace within New Zealand, yet researchers have paid little attention to its value perceived by students. This study explores counselling students’ perceptions of the effects of recording counselling interviews on themselves, their clients and on the counselling process. Design: Counselling students from five tertiary educational settings in New Zealand participated in individual or focus group interviews to discuss their experiences of recording counselling interviews. Findings: All interviewees indicated that recording initially curtailed their ability to be completely present in the counselling interview. Some thought this may have negatively influenced their clients’ ability to use the counselling session effectively. Most noted their own increased confidence over time. Almost all considered recording to be extremely beneficial to the development of effective counselling skills. Conclusion: Most students considered the benefits of recording to outweigh the drawbacks. Implications for continuing the practice of recording and playing back interviews in counsellor‐education programmes are considered.     

Asynchrony in discrete bimanual aiming: Evidence for visual strategies of coordination

The bimanual coupling literature supposes an inherent drive for synchrony between the upper limbs when making discrete bimanual movements. The level of synchrony is argued to be task dependent, reliant on the visual demands of the two targets, and the result of a complex pattern of hand and eye movements (Bingham, Hughes, & Mon-Williams, 2008 ; Riek, Tresilian, Mon-Williams, Coppard, & Carson, 2003 ). However, recent work by Bruyn and Mason ( 2009 ) suggests that temporal coordination is not solely influenced by visual saccades. In this experimental series, a total of 8 participants performed congruent movements to targets either near or far from the midline. Targets far from the midline, requiring a visual saccade, resulted in greater terminal asynchrony. Initial and terminal asynchrony were not consistent, but linked to the task demands at that stage of the movement. If the asynchrony evident at the end of a bimanual movement is due to a complex pattern of hand and eye movements then the removal of visual feedback should result in an increase in synchrony. Sixteen participants then completed congruent and incongruent bimanual aiming movements to near and/or far targets. Movements were made with or without visual feedback of hands and targets. Analyses revealed that movements made without visual feedback showed increased synchrony between the limbs, yet movements to incongruent targets still showed greater asynchrony. We suggest that visual constraints are not the sole cause of asynchrony in discrete bimanual movements.
