Reaction time and established risk factors for total and cardiovascular disease mortality: Comparison of effect estimates in the follow-up of a large, UK-wide, general-population based survey

Higher cognitive function is associated with faster choice reaction time (CRT), and both are associated with a reduced risk of mortality from all-causes and cardiovascular disease (CVD). However, comparison of the predictive capacity of CRT, an emerging risk factor, with that for established ‘classic’ risk factors for mortality, such as smoking, hypertension or obesity, is lacking. The purpose of this study was to compare the relative impact of CRT with a range of established risk factors for all-cause and CVD mortality. The UK Health and Lifestyle Survey (HALS) is a national sample survey of adults in England, Scotland, and Wales. In 1984/85, data on lifestyle factors, socioeconomic status, and health were collected for 9003 individuals. CRT data were available for 7414 individuals. With different predictor variables having differing coding structures, we used the relative index of inequality (RII) to explore the relation of a range of risk factors with mortality by computing the risk in disadvantaged (high risk; e.g., smokers) relative to advantaged (low risk; e.g., non-smokers) persons. During an average of 20 years of follow-up, there were 1289 deaths (568 ascribed to CVD). In age- and sex-adjusted models in which all-cause mortality was the outcome of interest, CRT mean (RII = 2.57, 95% CI = 1.98, 3.33) was the second most important predictor of death after smoking (RII = 3.03, 95% CI = 2.45, 3.75). For death from CVD, CRT mean (RII = 2.31, 95% CI = 1.55, 3.43) was again the second most important risk factor for death, behind systolic blood pressure (RII = 4.37, 95% CI = 3.03, 6.29). These analyses suggest that CRT, a moderately high correlate of intelligence, is an important risk factor for death from all-causes and CVD.     

Substance Abuse Counselor Certification Requirements: Is It Time for a Change?

The minimum professional training requirements of 32 state certifying bodies for substance abuse counselors were analyzed. Only 14 of the certifying boards included any of the Council for the Accreditation of Counseling and Related Educational Programs core knowledge areas in their training components for Certified Addictions Counselors. Specific training in counseling and drug and alcohol treatment issues also appeared to be minimal. The lack of specific drug and alcohol training brings the quality of preparation for substance abuse counselors into question.     

Recognizing Spirituality as an Important Factor in Counselor Supervision

Despite the recent, growing emphasis on spirituality in the counseling and psychotherapy literature, information regarding spirituality and the supervision process is limited. The purpose of this article is to help supervisors and supervisees enhance awareness of spiritual values in supervision. Factors such as counselor competency, conceptualization of spirituality, cross‐cultural awareness, and the similarity of clients' and counselors' values form a foundation for developing effective intervention and supervision strategies. A series of research questions is proposed to spur a program of empirical exploration.     

The Political Activity of Evangelical Clergy in the Election of 2000: A Case Study of Five Denominations

This article focuses on the political participation of ministers from five evangelical Protestant denominations that differ in theology, polity, and history. Despite such differences, these clergy respond to political influences in much the same fashion. We find that the standard theories of political participation have varying success in accounting for their political involvement. Sociodemographic explanations provide little help, but psychological engagement with politics has more explanatory power. Professional role orientations are the best predictors of actual participation. And the clergy who see moral reform issues as the most important confronting the country—and who hold conservative views on such issues—are most likely to become engaged. Finally, membership in Christian Right organizations serves to elicit more activity than might occur if ministers were left to internally motivated participation. Despite the emphasis on other contextual variables in some work on clerical politics, we find that communications exposures, congregational influences, and even the support of clerical colleagues have very limited independent effects on political involvement.     

Prevalence of dating violence and victimization: regional and gender differences

This report examines (1) the prevalence of dating violence victimization from a national sample of rural adolescents and (2) patterns by gender and region. Analyses are based on 20,274 adolescents who reported violence victimization using the Community Drug and Alcohol Survey. The relationship of dating violence with gender and region was assessed with HLM5 using Bernoulli's logistic regression. Approximately 16% of adolescents reported being a victim of dating violence. Females reported higher incidence of victimization than males. Dating violence is more prevalent in the South. While it is important to address the underlying values in society that may contribute to dating violence, it is equally productive to include regional and cultural values.     

The state of methods and tools for social systems change

The last decade or so has seen an increase in the rate of attention to systems change and the application of multiple theories to study and influence change in systems. This article considers how these theories, described in other articles in this issues, plus theories about complex adaptive systems open opportunities for us to continue to expand our repertoire of tools and methods to address systems change. These conceptual frameworks, tools, and methods are expected to help us increase our capacity to study and influence both planned and self-organizing systems change. New tools and methods have emerged and others are needed to help us continue to explore and influence the complex social systems within which we operate.     

Grammaticality sensitivity in children with early focal brain injury and children with specific language impairment

Grammaticality judgments and processing times associated with violation detection were examined in typically developing children, children with focal brain lesions (FL) acquired early in life, and children with specific language impairment (SLI). Grammatical sensitivity in the FL group, while below typically developing children, was above levels seen in children with SLI. Age effects were noted with developmental changes in sensitivity extending into adolescence. Developmental delays in grammatical processing were particularly pronounced for children with SLI, who showed sensitivity levels below those of younger typically developing children. Sensitivity to agreement violations was also protracted in the SLI group providing further evidence of the vulnerability of morphology, a pattern not unlike that seen in adult aphasics. Findings for the FL group provide compelling evidence of neural and behavioral plasticity in children with early unilateral brain injury. Moreover, results from these children underscore how very different compensatory organization may be compared to profiles seen in adult aphasics who have comparable lesions. In contrast, although it was expected that the SLI children would perform below the typically developing children, the disadvantage seen with respect to the FL group suggests that the underlying pathology responsible for SLI may be more pervasive and less plastic than the focal pathology of children with early brain damage.     

The development of morphosyntactic ability in atypical populations: The acquisition of tag questions in children with early focal lesions and children with specific-language impairment

We examined the development of some features of morphosyntactic ability, specifically the acquisition of auxiliaries and use of agreement marking, along with sentence processing capacity. We used a conceptually simple task called the Tags Question Task, which is a method for evaluating a number of language processes in the production of a commonly used, familiar linguistic device. We compared the performance of children with early focal lesions (N=21), children with specific-language impairment (N=24), and typically developing children (N=24) matched in age and nonverbal ability; additional analyses involved comparisons of children matched on performance level. The data converge to support a "delayed" development of language behavior in our clinical groups, as overall patterns of performance and age-related changes on individual tag features and tag questions were strikingly similar in all three groups across a number of methods of comparison. Implications for theories of the development of brain-language relationships as they pertain to early focal brain damage, specific-language impairment, and the language acquisition process in typically developing children are discussed.     

Modeling dynamic resource utilization in populations with unique constraints: preadolescents with and without Down syndrome

In this study we used a damped inverted pendulum and spring with an escapement function model to compare the global levels of stiffness and forcing used by 12 preadolescents with Down syndrome (DS) and 12 with typical development (TD). Participants walked overground at their self-selected speed and on a treadmill at speeds slower and faster than overground. Children with DS, who are characterized as hypotonic with reduced capacity for producing muscle force, exhibited significantly higher levels of stiffness and forcing (angular impulse) when walking on the treadmill and higher forcing but not stiffness overground, than children with TD. Both groups adapted to imposed speed increases similarly by increasing their global stiffness and angular impulse. We propose children with DS increased stiffness in order to overcome their hypotonia and joint laxity, thus, optimizing on stability, rather than metabolic efficiency. Higher angular impulse values for children with DS may reflect higher energy cost associated with increasing stiffness and their inherent biomechanical and physiological characteristics that reduce efficiency. We conclude that the inverted pendulum and spring with escapement function model is a useful tool for uncovering solutions to movement problems-solutions that reflect the dynamic resources of the individual and ones that are discovered, rather than prescribed.     

The Interface Between the Practice of Medical Genetics and Human Genetic Research: What Every Genetic Counselor Needs to Know

Genetic counselors have historically used human genetic research as an advanced information resource for their patients. Most commonly, this has been via access to information provided by gene identification studies in advance of commercial testing. More recently genetic counselors have been participating in human genetic research studies as part of the investigative team. This review provides a framework to help genetic counselors in research and clinical practice understand the historical perspectives, ethical principles, and federal regulations that govern the current practice of human subject research. Special consideration is given to the IRB process and unique issues in human genetic research. This overview is intended to help improve the ability of genetic counselors to act as advocates for their patients.
