Serotonin transporter genetic variation and biased attention for emotional word stimuli among psychiatric inpatients

The short allele in a variable repeat sequence of the promoter region of the serotonin transporter gene (5-HTTLPR) has been associated with stronger activation in brain regions critical for processing emotional stimuli. The authors examined whether variants of the 5-HTTLPR promoter polymorphism were also associated with individual differences in attentional biases for emotional stimuli. Words related to anxious and dysphoric emotional states were presented to psychiatric inpatients in a standard dot-probe reaction time task. Compared with participants with two long alleles, carriers of the short 5-HTTLPR allele exhibited a stronger attentional bias for anxious word stimuli. No genetic group difference was observed for dysphoric word stimuli. Findings from this preliminary study highlight the potential for integrating genetic and cognitive models of psychopathology.     

Gender differences and developmental change in externalizing disorders from late adolescence to early adulthood: A longitudinal twin study

Using data from over 1,000 male and female twins participating in the Minnesota Twin Family Study, the authors examined developmental change, gender differences, and genetic and environmental contributions to the symptom levels of four externalizing disorders (adult antisocial behavior, alcohol dependence, nicotine dependence, and drug dependence) from ages 17 to 24. Both men and women increased in symptoms for each externalizing disorder, with men increasing at a greater rate than women, such that a modest gender gap at age 17 widened to a large one at age 24. Additionally, a mean-level gender difference on a latent Externalizing factor could account for the mean-level gender differences for the individual disorders. Biometric analyses revealed increasing genetic variation and heritability for men but a trend toward decreasing genetic variation and increasing environmental effects for women. Results illustrate the importance of gender and developmental context for symptom expression and the utility of structural models to integrate general trends and disorder-specific characteristics.     

The prevention of depressive symptoms in low-income, minority children: two-year follow-up

We present 2-year follow-up data on the efficacy of the Penn Resiliency Program (PRP), a school-based depression prevention program, with low-income, racial/ethnic minority children. This program taught cognitive and social problem-solving skills to 168 Latino and African American middle school children who were at-risk for developing depressive symptoms by virtue of their low-income status. We had previously reported beneficial effects of the PRP up to 6 months after the conclusion of the program for the Latino children, but no clear effect for the African American children. In this paper, we extend the analyses to 24 months after the conclusion of the PRP. We continue to find some beneficial effects for the Latino children and no differentially beneficial effect for the African American children. Implications of findings and future research directions are discussed.     

Recognition of nonverbal affect and schizotypy

The authors assessed the degree to which schizotypal characteristics in a nonclinical population were associated with impairments in the ability to correctly identify emotions as expressed in facial, paralinguistic, and postural cues. Participants completed the Schizotypal Personality Questionnaire (SPQ; A. Raine, 2005), and the 3 receptive subtests of the Diagnostic Analysis of Nonverbal Accuracy-2 (DANVA2; S. Nowicki Jr., 2005). The SPQ subscales No close friends and Suspiciousness were correlated with impaired ability to correctly identify postural affective cues on the DANVA2. Unusual perceptual experiences were correlated with deficits in the ability to identify emotions on the DANVA2 paralinguistic measure. Impairments in the ability to correctly perceive and respond to expressions of affect may be part of a deficit in social cognition that contributes to development of schizotypal traits.     

Beliefs about personality change and continuity

Lay conceptions of personality change and continuity were examined in a sample of 112 undergraduates. Participants rated their personal change over 5 years (past or future), the change they perceived to be normative over 10-year age spans between 15 and 65, their beliefs about whether personality is fixed or malleable (“lay theories”) and their beliefs about the causes of personality change and continuity. Beliefs about normative personality change generally corresponded to research evidence on adult trajectories of the Big Five factors, with some age bias, whereas recalled and anticipated personal change tended to be more positive than these norms. Participants tended to endorse environmental causes more for personality change than for continuity. Lay theories were not consistently associated with these causal beliefs, or with beliefs about personal and normative change.     

Telephone versus print delivery of an individualized motivationally tailored physical activity intervention: Project STRIDE.

OBJECTIVE: Given that only 25% of Americans meet physical activity recommendations, there is a need to develop and disseminate effective, evidence-based interventions to promote physical activity. The authors tested 2 delivery channels, telephone and print, to determine whether one was more effective in promoting physical activity. DESIGN: The authors randomly assigned 239 healthy, sedentary adults to (a) telephone-based individualized feedback, (b) print-based individualized feedback, or (c) contact control. Both intervention arms were guided by a motivationally tailored, theoretically driven computer expert system. MAIN OUTCOME MEASURES: Physical activity as measured by the 7-day Physical Activity Recall interview. RESULTS: At 6 months, both telephone and print arms significantly increased in minutes of moderate intensity physical activity compared with control, with no differences between the intervention arms. At 12 months, print participants reported a significantly greater number of moderate intensity minutes than both telephone and control participants, who did not differ. CONCLUSION: Results suggest that both telephone and print enhance the adoption of physical activity among sedentary adults; however, print interventions may be particularly effective in maintaining physical activity in the longer term.     

So Why Aren't Counselors Reporting n = 1 Research Designs?

There is a growing urgency for counseling to be evidence based. The n = 1 research paradigm offers counselors in the field an opportunity to evaluate their clinical casework and report this in methodologically rigorous form to their peers. Data from the past 20 years of the Journal of Counseling & Development indicate that n = 1 studies constitute just over 1% of the total articles reporting research data, and possible reasons for this are discussed, with some suggestions made for overcoming this reluctance.     

Work, Well–being and Vocational Education: The Ethical Significance of Work and Preparation for Work

David Carr's account of the nature of professional work is described and examined. It is argued that Carr's criteria for distinguishing between professional and non–professional work are not adequate. The criteria are as follows: the professions' essential role in promoting human flourishing; their contestability; their direct concern for the well–being of clients; their provision of a high degree of autonomy for practitioners. They do not mark out a qualitative difference between professions and other occupations. Carr's notion of civic necessities applies to what he describes as non–professional as well as to professional work. The role of commercial considerations in the usefulness of some kinds of work is considered and a distinction is made between technical and occupational virtues. Carr treats professional virtues as occupational virtues without appreciating that nearly all occupations have both occupational and technical virtues. A significant part of the wouthwhileness of work is bound up with practice of the relevant occupational virtues.
