Effects of a meaningful, a discriminative, and a meaningless stimulus on equivalence class formation

Thirty college students attempted to form three 3-node 5-member equivalence classes under the simultaneous protocol. After concurrent training of AB, BC, CD, and DE relations, all probes used to assess the emergence of symmetrical, transitive, and equivalence relations were presented for two test blocks. When the A-E stimuli were all abstract shapes, none of 10 participants formed classes. When the A, B, D, and E stimuli were abstract shapes and the C stimuli were meaningful pictures, 8 of 10 participants formed classes. This high yield may reflect the expansion of existing classes that consist of the associates of the meaningful stimuli, rather than the formation of the ABCDE classes, per se. When the A-E stimuli were abstract shapes and the C stimuli became S(D)s prior to class formation, 5 out of 10 participants formed classes. Thus, the discriminative functions served by the meaningful stimuli can account for some of the enhancement of class formation produced by the inclusion of a meaningful stimulus as a class member. A sorting task, which provided a secondary measure of class formation, indicated the formation of all three classes when the emergent relations probes indicated the same outcome. In contrast, the sorting test indicated "partial" class formation when the emergent relations test indicated no class formation. Finally, the effects of nodal distance on the relatedness of stimuli in the equivalence classes were not influenced by the functions served by the C stimuli in the equivalence classes.     

Bending the Curve: A Community-Based Behavioral Parent Training Model to Address ADHD-Related Concerns in the Voluntary Sector in Denmark

Limited access to evidence-based behavioral parent training (BPT) for addressing attention deficit/hyperactivity disorder (ADHD) has been a growing concern internationally. Models to improve access to BPT are needed, particularly those that can be readily implemented in community settings and that leverage the potential workforce to increase capacity to deliver BPT. The purpose of this study was to evaluate a BPT model which included oft-used content, methods, processes of BPT (common-elements), non-professionally delivered (task-shifted/shared) BPT intervention, and an efficient ancillary support system (training, fidelity, and supervision methods) for families of youth with parental concerns about ADHD. In a randomized controlled trial of 161 families of children (79% male; mean age 7.04 [1.55]), the Caring in Chaos (CiC) BPT model, delivered by community volunteers across 12 community-based sites in Denmark, was compared to a wait-list control condition on key child and parent outcomes at immediate post-treatment and 4-month follow-up assessment points. Results suggested that the CiC model led to significantly greater improvement in parenting behavior, parenting sense of competence, child functional impairment, parental stress and parental depressive symptoms compared to the wait list condition at immediate post-treatment, with maintenance of gains in most of these areas at follow-up assessment. No effect of intervention was found on ADHD symptoms. The results of this study suggest that developing efficient BPT intervention models, such as the CiC model, can result in readily implemented interventions by a variety of individuals in community settings. Such models are necessary to bend the curve on addressing unmet needs of families of youth with concerns about ADHD.     

Psychosocial Conditions of Women Awaiting Genetic Counseling: A Population-based Study

The decision whether to undergo genetic counseling for hereditary breast and ovarian cancer is complex. Knowledge about the psychosocial conditions of women who are awaiting counseling is sparse. We aimed to compare the psychosocial conditions of women awaiting genetic counseling with those of women in two reference groups. We included 567 women referred to genetic counseling for hereditary risk of breast or ovarian cancer (Genetic Group), 689 women referred to mammography (Mammography Group) and a random sample of 2,000 women from the general population (Population Group). One to 4 weeks before the first counseling session or mammography, data were collected by questionnaires. Both women affected with cancer and unaffected women in the Genetic Group appeared to have a somewhat higher prevalence of cancer-specific-distress than the corresponding reference groups. Further research on the effect of pre- counseling interventions appear warranted in addition with exploring a potential association between waiting time and cancer-specific distress.     

Adolescent Gender and Age Differences in Responsiveness to Functional Family Therapy

The current study contributes to a sparse literature on moderators of Functional Family Therapy (FFT) by examining whether responsiveness to FFT, measured by a broad range of outcomes, varies by adolescent gender, age, and their interaction. This study was informed by 687 families (n, adolescents = 581; n, caregivers = 933) and utilized a pre–post comparison design. Fixed-effects regressions with gender, age, and their interaction included as explanatory variables were conducted to calculate the average change in youth mental health, callous–unemotional traits, academic outcomes, substance use, and family functioning. Moderation analyses revealed that according to parent report, girls had significantly greater improvements in peer problems and family functioning, and boys benefited more in increased liking of school. There were differential effects by age, such that older youth had less beneficial mental health outcomes and a smaller decrease in frequency of hash use. The gender by age interaction was significant for adolescents’ report of mental health and family functioning outcomes, which suggests that girls benefit from FFT less than boys during early adolescence, but benefit more than boys in late adolescence. This finding adds to literature which has evidenced that family functioning is particularly important for girls by suggesting that FFT is important for improving older girls’ mental health and family functioning in particular. The study’s results expand the examination of outcomes of FFT to include academic outcomes, and provide insight into key factors that should be considered in addressing adolescent behavioral problems and family functioning.     

I WALK THE LINE: COMMENT ON MIKAEL LEIDENHAG ON THEISTIC EVOLUTION AND INTELLIGENT DESIGN

Is theistic evolution (TE) a philosophically tenable position? Leidenhag argues in his article “The Blurred Line between Theistic Evolution and Intelligent Design” that it is not, since it, Leidenhag claims, espouses a view of divine action that he labels “natural divine causation” (NDC), which makes God explanatory redundant. That is, in so far as TE does not invoke God as an additional cause alongside natural causes, it is untenable. Theistic evolutionists should therefore “reject NDC and affirm a more robust notion of divine agency.” However, this will, Leidenhag claims, have the effect that theistic evolutionists “will move their position significantly closer to Intelligent Design,” and so the line between TE and intelligent design is (or ought to be?) blurred. If successful, the criticism by Leidenhag would be bad news for theists who want to take science seriously and good news for those scientistic atheists according to whom there simply is no scientifically respectable way of combining theism and modern natural science in an overarching worldview. So, is TE stuck between a rock (of redundancy) and a hard place (of pseudo-science)? No, at least not due to the criticism offered by Leidenhag—but maybe religious naturalism is?     

To Have Life,and Have It Abundantly! Health and Well-Being in Biblical Perspective

Epidemiological studies researching the impact of participation in religious activities on the overall health and well-being of individuals suggest that having faith and practicing religion is good since they represent expense free, non-medical coping mechanisms accessible to everyone. Faith and religion, thus, can serve for a large number of people as potential reservoirs for cultivating well-being and maintaining health, thereby cutting health-care costs significantly. This begs the question if such pragmatic instrumentalization does do justice to faith and religion in the first place. The article investigates this question taking the Christian biblical tradition as an example by, first, identifying texts speaking of ‘health’ across different Bible versions (I), second, by sketching related concepts of ‘health’ (II) and, finally, by assessing the actual extent to which biblical tradition supports the quest for health and well-being (III).
