From a single-level analysis to a multilevel analysis of single-case experimental designs

Multilevel modeling provides one approach to synthesizing single-case experimental design data. In this study, we present the multilevel model (the two-level and the three-level models) for summarizing single-case results over cases, over studies, or both. In addition to the basic multilevel models, we elaborate on several plausible alternative models. We apply the proposed models to real datasets and investigate to what extent the estimated treatment effect is dependent on the modeling specifications and the underlying assumptions. By considering a range of plausible models and assumptions, researchers can determine the degree to which the effect estimates and conclusions are sensitive to the specific assumptions made. If the same conclusions are reached across a range of plausible assumptions, confidence in the conclusions can be enhanced. We advise researchers not to focus on one model but conduct multiple plausible multilevel analyses and investigate whether the results depend on the modeling options.     

The Efficacy of Child Parent Relationship Therapy for Adopted Children With Attachment Disruptions

This pilot study examined the effectiveness of child parent relationship therapy (CPRT; Landreth & Bratton, 2006 ) with 61 adoptive families. Statistically significant findings and large treatment effects on all measures indicated the effectiveness of CPRT over the wait‐list control condition on reducing child behavior problems and increasing parental empathy. The results provide preliminary support for CPRT as a responsive intervention for adoptive families with children presenting with attachment difficulties.     

An ethnographic study of issues surrounding the provision of sport opportunities to young men from a western Canadian inner-city

ObjectivesThe purpose of this study was to examine issues surrounding the provision of sport opportunities to young men from inner-city areas of Edmonton, Alberta, Canada. More specifically, the research question was: What are the benefits, constraints, and opportunities associated with providing sport programs to young men from inner-city areas?DesignEthnography.MethodsData were collected via 15 months of participant observation and interviews with 12 youth workers who were responsible for the provision of various sport programs to young inner-city dwellers. Analysis was framed around personal, social, and structural issues.ResultsAt a personal level sport provided young men with an outlet for overcoming boredom and a temporary reprieve from the conditions of their daily lives. At a social level sport provided opportunities for relationship building between the youth workers and the young men. However, enduring structural constraints associated with economic and social inequality and the lack of a coordinated approach to the delivery of services restricted the influence that sport could have in the lives of the young men.ConclusionThis study provided some precise understandings of the benefits, constraints, and opportunities associated with providing sport programs to members of specific populations in certain inner-city circumstances. Findings, therefore, have the potential to inform public health policy concerning the use of sport-for-development programming in such contexts.     

A Defense of Partisan-Science: An Assessment of Stenmark's Non-Partisan Science3

Abstract

In his influential book “How to Relate Science and Religion,” Mikael Stenmark argues for the legitimateness of what he calls “partisan science”: “science that is aligned with or supports a particular ideology, religion, or worldview over another.” However, he maintains that we should make an exception: the justification phase of science (phase 3) requires neutral science. Thus, he argues for “non-partisan science₃.” In this article, I assess his arguments for non-partisan science₃. I find them wanting and I will argue for partisan science₃ and maintain that we should adhere to “Augustinian” or “theistic science.”     

Evaluation of a School-Based Social Skills Program for Children With Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder (ADHD) is prevalent among school-aged children. An associated feature of the disorder is a deficit in social functioning, which can be detrimental in terms of long-term outcomes. Therefore, it is crucial to identify evidence-based interventions which can improve the social skills of children with ADHD. The current study was an evaluation of a school-based social skills training program, called Working Together: Building Children's Social Skills Through Folk Literature. The modified version of the program with generalization enhancers was delivered in three schools to 16 children over a 10-week period. Results indicated that this program was effective for improving social skills in children with ADHD, particularly for children with poor pragmatic language skills.     

Thought Suppression in Spider-Fearful and Nonfearful Individuals

The authors examined the suppression of spider-related thoughts in spiderfearful (n = 23) and nonfearful (n = 22) individuals. Participants were primed with vivid pictures of spiders and a story about spiders. Next, they were randomly assigned to 1 of 2 conditions: (a) suppression of thoughts associated with the previously presented spiderrelated stimuli or (b) free expression of any thoughts, including those related to the spider-related stimuli. All participants completed a subsequent free-expression exercise. Results indicated that spider-fearful individuals expressed thoughts about the spider-related stimuli for a longer length of time than did nonfearful individuals, particularly in the suppression condition. Participants in both groups demonstrated a rebound of thoughts associated with the spider-related stimuli following suppression. The authors propose that the priming of feared stimuli makes suppression of fear-related thoughts particularly difficult for fearful individuals, perhaps by activating a state of heightened arousal.     

Mirror neurons, the representation of word meaning, and the foot of the third left frontal convolution

Previous neuroimaging research has attempted to demonstrate a preferential involvement of the human mirror neuron system (MNS) in the comprehension of effector-related action word (verb) meanings. These studies have assumed that Broca's area (or Brodmann's area 44) is the homologue of a monkey premotor area (F5) containing mouth and hand mirror neurons, and that action word meanings are shared with the mirror system due to a proposed link between speech and gestural communication. In an fMRI experiment, we investigated whether Broca's area shows mirror activity solely for effectors implicated in the MNS. Next, we examined the responses of empirically determined mirror areas during a language perception task comprising effector-specific action words, unrelated words and nonwords. We found overlapping activity for observation and execution of actions with all effectors studied, i.e., including the foot, despite there being no evidence of foot mirror neurons in the monkey or human brain. These "mirror" areas showed equivalent responses for action words, unrelated words and nonwords, with all of these stimuli showing increased responses relative to visual character strings. Our results support alternative explanations attributing mirror activity in Broca's area to covert verbalisation or hierarchical linearisation, and provide no evidence that the MNS makes a preferential contribution to comprehending action word meanings.
