Four studies on how past and current suicidality relate even when "everything but the kitchen sink" is covaried

T. E. Joiner's (2004, in press) theory of suicidal behavior suggests that past suicidal behavior plays an important role in future suicidality. However, the mechanism by which this risk is transferred and the causal implications have not been well studied. The current study provides evaluation of the nature and limits of this relationship across 4 populations, with varying degrees of suicidal behavior. Across settings, age groups, and impairment levels, the association between past suicidal behavior and current suicidal symptoms held, even when controlling for strong covariates like hopelessness and symptoms of various Axis I and II syndromes. Results provide additional support for the importance of past suicidality as a substantive risk factor for later suicidal behavior.     

The stability of vocational interests from early adolescence to middle adulthood: a quantitative review of longitudinal studies

The present meta-analysis examined the stability of vocational interests from early adolescence (age 12) to middle adulthood (age 40). Stability was represented by rank-order and profile correlations. Interest stability remained unchanged during much of adolescence and increased dramatically during the college years (age 18-21.9), where it remained for the next 2 decades. Analyses of potential moderators showed that retest time interval was negatively related to interest stability and that rank-order stability was less stable than profile stability. Although cohort standings did not moderate stability, interests of the 1940s birth cohort were less stable than those of other cohorts. Furthermore, interests reflecting hands-on physical activities and self-expressive/artistic activities were more stable than scientific, social, enterprising, and clerical interests. Vocational interests showed substantial continuity over time, as evidenced by their higher longitudinal stability when compared with rank-order stability of personality traits. The findings are discussed in the context of psychosocial development.     

Beyond the Frying Pan: Addressing Work Issues with Women in Therapy

In recent years, mental health practitioners have been exploring how women are balancing work and family. Given how this issue affects womens experiences in the corporate world and at home, marriage and family therapists are attempting to consider this concern as they treat female clients individually and within relational systems. Few articles and studies have examined the issues female employees face in the workplace and how the issues influence the therapeutic process. In this article, the authors examine the organizational, sociological, and cultural challenges women deal with at work and apply these areas to the therapeutic context. The authors present a case study of a female client enduring a difficult work situation, discussing how to view and approach this case from a feminist family therapy perspective.     

Vulnerability of older adults to deception in prison and nonprison contexts

Media reports frequently depict older adults as victims of deception. The public perceives these stories as particularly salient because older adults are seen as fragile victims taken advantage of because of trusting behaviors. This developmental investigation of deception detection examines older and younger adults interacting in 2 contexts, prison and the "free world," to discover whether older adults are vulnerable to deception. Younger prisoners were found to be lie biased. Older adults were better able to discriminate lies than younger adults, and this effect was localized primarily to older female adults. Findings indicate that discriminability strongly increases from younger to older age for women, whereas men do not show an improvement, as age increases, in making decisions about statement veracity.     

Equating tasks and sustaining attention in children and adults: the methodological and theoretical utility of d' matching

The present study develops a method to create task equivalency for children and adults in vigilance research. Experiment 1 employed the signal detection index of perceptual sensitivity (d') to calibrate vigilance tasks for 32 children (ages 7-8) and 32 adults. The results of Experiment 1 suggest that task equivalency across groups can be attained, and a vigilance decrement was observed for children. In Experiment 2, the task parameter of event rate was manipulated across two vigils. Again, 32 children (ages 7-8) and 32 adults participated. The results suggest that a reverse event rate effect emerged for both children and adults. In addition, developmental differences in response to the event rate manipulation and with respect to the vigilance decrement emerged: Children benefited less from the manipulation and were more likely to demonstrate a vigilance decrement than were adults. No developmental differences emerged for the sensitivity decrement. The results are explained with reference to how task demands interact with participant arousal, and implications for development and for future research are discussed.     

Patterns of continuity: a dynamic model for conceptualizing the stability of individual differences in psychological constructs across the life course

In contemporary psychology there is debate over whether individual differences in psychological constructs are stable over extended periods of time. The authors argue that it is impossible to resolve such debates unless researchers focus on patterns of stability and the developmental mechanisms that may give rise to them. To facilitate this shift in emphasis, they describe a formal model that integrates 3 developmental processes: stochastic-contextual processes, person-environment transactions, and developmental constancies. The theoretical and mathematical analyses indicate that this model makes novel predictions about the way in which test-retest correlations are structured across a wide range of ages and test-retest intervals. The authors illustrate the utility of the model by comparing its predictions against meta-analytic data on Neuroticism. The discussion emphasizes the value of focusing on patterns of continuity, not only as phenomena to be explained but as data capable of clarifying the developmental processes underlying stability and change for a variety of psychological constructs.     

College students, tattoos, and sexual activity

This research examined the association of having a tattoo and engaging in premarital sexual intercourse. Data gathered from a convenience sample of 450 college students indicated that tattooed respondents were substantively and significantly more likely to be sexually active than nontattooed college students. Tattooed men became sexually active at a significantly earlier age than nontattooed men but no such difference was found between tattooed and nontattooed college women.     

Adaptation of panic-related psychopathology measures to Russian

The study reports results of adaptation of panic-related psychopathology measures to Russian, including the Anxiety Sensitivity Index (ASI), the Agoraphobic Cognitions Questionnaire (ACQ), and the Mobility Inventory for Agoraphobia (MIA). Psychometric properties (e.g., reliability, factor structure, endorsement) and external validity of the adaptations were evaluated in a representative sample of Moscow residents (N = 390) and Ukrainian undergraduates (N = 492). The adapted ASI was generally equivalent to the original English-language version. The ACQ showed structural equivalency but did not exhibit expected specificity to panic. Finally, the MIA displayed notable structural discrepancies but had external validity comparable to the original.     

A methodology for assessing the functions of emerging speech in children with developmental disabilities

An approach based on Skinner's (1957) theory of verbal behavior has been developed to understand and teach elementary communication skills to children with autism and developmental disabilities (Sundberg & Partington, 1998). However, few studies have directly examined the characteristics of emerging language in children with developmental disabilities. The purpose of this study was to develop and evaluate an assessment for identifying the elementary functions of vocal speech in children. Participants were 4 children with developmental disabilities, aged 6 years to 12 years, who exhibited at least one distinguishable vocal response (word or phrase) frequently in the natural environment. The assessment focused on three verbal operants delineated by Skinner (mand, tact, and intraverbal). One or more functions were identified for at least one vocal response of each child. Results suggested that this assessment would be useful for (a) evaluating Skinner's theory, (b) guiding decisions about language training for individual children, and (c) studying the nature of expressive language development in children with developmental disabilities.     

Knowledge of resources and competitors in human foraging

The allocation of human participants to resources was studied by observing the population dynamics of people interacting in real time within a common virtual world. Resources were distributed in two spatially separated pools with varying relative reinforcement rates (50–50, 65–35, or 80–20). We manipulated whether the participants could see each other and the distribution of the resources. When the participants could see each other but not the resources, the richer pool was underutilized. When the participants could see the resources but not each other, the richer pool was overutilized. In conjunction with prior experiments that correlated the visibility of agents and resources (Goldstone & Ashpole, 2004), these results indicate that participants’ foraging decisions are influenced by both forager and resource information. The results suggest that the presence of a crowd at a resource is a deterring, rather than an attractive, factor. Both fast and slow oscillations in the harvesting rates of the pools across time were revealed by Fourier analyses. The slow waves of crowd migration were most prevalent when the resources were invisible, whereas the fast cycles were most prevalent when the resources were visible and the participants were invisible.
