Multisystemic therapy for young offenders: families' experiences of therapeutic processes and outcomes

Multisystemic Therapy (MST) has been found to be effective in reducing youth antisocial behavior, but little is known about the process and impact of MST from the perspective of families themselves. This qualitative study explored parents' and young people's experiences of MST, focusing on aspects of the intervention that promoted or limited change. Thirty-seven semistructured interviews were conducted with a consecutive sample of 21 families (21 parent interviews, 16 young people) who had participated in a randomized controlled trial of MST for young offenders in the United Kingdom. Thematic analysis yielded 10 themes, organized into two domains: (a) engagement in MST and initial processes of change captures the central importance of the therapeutic relationship and the MST engagement model in families' positive experiences of MST; and (b) outcomes are complex reflects the range of positive outcomes reported (notably increased parental confidence and skills, improved family relationships, a return to education, and greater reflection and aspiration on the part of the young person) and mixed behavior outcomes. Even when the young person had reoffended, respondents indicated a range of other benefits for the family. The findings support the MST theory of change as well as point to some outcomes not usually measured in MST outcome studies. They also suggest some adaptations that may increase the impact of the intervention, including more attention to the influence of deviant peers, and ongoing support for families struggling to maintain strategies beyond the prescribed treatment period.     

Inferring facts from fiction: reading correct and incorrect information affects memory for related information

People can acquire both true and false knowledge about the world from fictional stories. The present study explored whether the benefits and costs of learning about the world from fictional stories extend beyond memory for directly stated pieces of information. Of interest was whether readers would use correct and incorrect story references to make deductive inferences about related information in the story, and then integrate those inferences into their knowledge bases. Participants read stories containing correct, neutral, and misleading references to facts about the world; each reference could be combined with another reference that occurred in a later sentence to make a deductive inference. Later they answered general knowledge questions that tested for these deductive inferences. The results showed that participants generated and retained the deductive inferences regardless of whether the inferences were consistent or inconsistent with world knowledge, and irrespective of whether the references were placed consecutively in the text or separated by many sentences. Readers learn more than what is directly stated in stories; they use references to the real world to make both correct and incorrect inferences that are integrated into their knowledge bases.     

Children’s Acceptance of Others with Disability: The Influence of a Disability-Simulation Program

Elementary school is a transitional and impressionable period for any child. In inclusive classroom settings, children with disabilities may experience the challenges of acceptance and integration into peer relationships. The experience of children with disabilities in such classrooms can be positive if their classmates are accepting and open. One way to encourage these attitudes is by increasing awareness through disability-simulation. This study evaluates an existing school program, whose goal is to increase acceptance of others with disability. We surveyed students to assess the influence of the program. An adapted acceptance scale was distributed to students before and after participation in the program. Our hypothesis was that student acceptance would increase after participating in the program. Additionally, we hypothesized that physical, visual, and auditory disabilities would be easier for students to understand, making acceptance scores for these disabilities higher than those for a learning disability. We report changes in acceptance using group means. Our results reveal that post-survey responses showed higher acceptance than pre-survey responses, especially for auditory disabilities. Other significant findings include differences in attitudes between the two schools and differences based on prior experience with someone with a disability. By evaluating the effectiveness of this type of program (whose efficacy has been controversial in the literature), this study can provide teachers, administrators, genetic counselors, and parents with a better idea of how to address children’s attitudes towards peers. In our study, the effectiveness of promoting understanding through disability-simulation has proven its worth to improve children’s acceptance.     

Racial and Ethnic Differences in Direct-to-Consumer Genetic Tests Awareness in HINTS 2007: Sociodemographic and Numeracy Correlates

To examine the association of 1) race/ethnicity and 2) numeracy with awareness of DTC genetic tests. Secondary analysis of 6,754 Hispanic, black, and white adult respondents to the National Cancer Institute’s 2007 Health Information National Trends Survey (HINTS). Logistic regression was used to examine sociodemographic predictors of DTC genetic tests awareness including race/ethnicity, income, education, and gender. Next, two numeracy variables were added to the model. After controlling for sociodemographic variables, black respondents were significantly less likely to have heard of DTC genetic tests compared to white respondents (OR = 0.79; CI: 0.65–0.97). When numeracy variables were added to the model, the effect of black race was no longer significant (OR = 0.84; CI: 0.69–1.04). Hispanic respondents did not significantly differ from white respondents in awareness of DTC genetic tests. Other significant correlates of DTC genetic tests awareness in the full model included education, income, age, and numeracy variables including degree to which people use medical statistics and numbers to make health decisions, and preference for words or numbers when discussing “the chance of something happening.” Although black respondents were generally less aware of DTC genetic tests than white respondents, this relationship appears to be partially mediated by numeracy.     

Assuming too much from 'familiar' brain potentials

Familiarity is sometimes associated with midfrontal old/new (FN400) signals, but investigators assume too much by inferring familiarity whenever they identify these signals. We describe how Rosburg and colleagues (2011) made this assumption, yielding potentially faulty conclusions about the recognition heuristic. We provide an alternative interpretation emphasizing implicit processing that can underlie decision-making.     

Alternate behavioural measurements following a single operant training regime demonstrate differences in memory retention

Frequently studies of learning and memory measure a single focal behaviour; however it is likely that any learning paradigm will alter multiple behavioural traits in the same animal. We used video footage of the great pond snail (Lymnaea stagnalis), collected immediately prior to both training and testing for memory in response to operant conditioning to reduce aerial respiration, to measure two additional alternate behavioural traits: reducing the size of the pneumostome (breathing orifice) opening and shell tilt to cover the pneumostome. Typically, the training regime used here results in memory to reduce the number of breathing attempts lasting 24?h but not 72?h. However, memory duration when measured using the two additional behavioural traits differed significantly; shell tilt was short-lived lasting less than 1?h following training, whereas the reduction in pneumostome size was still apparent 72?h following training. Therefore, conclusions about the ability of L. stagnalis to retain memory in response to a single type of training regime will differ significantly depending on the focal behavioural trait measured. A significant correlation between the reduction in opening attempts and visible pneumostome area indicated that these behavioural traits are co-specialised, whereas pneumostome opening and shell tilt behaviour varied independently.     

Investigating the acute effect of an aerobic dance exercise program on neuro-cognitive function in the elderly

ObjectiveThe present study investigated the types of aerobic dance programs that positively impact cognition, such as executive function, in elderly people.DesignRandomized controlled trial.MethodThe study compared the effects of acute aerobic dance exercise on cognitive performance using two 40-min aerobic dance programs. Thirty-four elderly participants, aged 65–75 years, were randomly assigned into either free (N = 17) or combination (N = 17) style workout groups. The free style (FR) workout consisted of several patterns of movement, while the combination style (CB) workout consisted of similar patterns of movement to FR, but the patterns were joined to form a long choreographic routine. Both dance programs were controlled to be the same in exercise intensity, approximately 40% heart rate reserve. Reaction time and correct rates were measured using a task-switching reaction time test to evaluate executive cognitive performance immediately before and after the 40-min dance exercise.ResultsA two-way (dance program × pre-post dance exercise) repeated-measures analysis of variance for switch reaction time increase (switch cost) demonstrated a significant interaction (p = .006), showing that the switch cost in the CB group became smaller after the dance exercise than before (p = .009).ConclusionThe results suggest that the executive cognitive network was facilitated in a CB dance workout that has a dual-task nature and induces movement (task) interference with unexpected movement changes.     

Accuracy in parameter estimation for ANCOVA and ANOVA contrasts: sample size planning via narrow confidence intervals

Contrasts of means are often of interest because they describe the effect size among multiple treatments. High-quality inference of population effect sizes can be achieved through narrow confidence intervals (CIs). Given the close relation between CI width and sample size, we propose two methods to plan the sample size for an ANCOVA or ANOVA study, so that a sufficiently narrow CI for the population (standardized or unstandardized) contrast of interest will be obtained. The standard method plans the sample size so that the expected CI width is sufficiently small. Since CI width is a random variable, the expected width being sufficiently small does not guarantee that the width obtained in a particular study will be sufficiently small. An extended procedure ensures with some specified, high degree of assurance (e.g., 90% of the time) that the CI observed in a particular study will be sufficiently narrow. We also discuss the rationale and usefulness of two different ways to standardize an ANCOVA contrast, and compare three types of standardized contrast in the ANCOVA/ANOVA context. All of the methods we propose have been implemented in the freely available MBESS package in R so that they can be easily applied by researchers.     

Clinical Reflection and Ritual as Forms of Participation and Interaction: Reply to Bass and Stern

We agree with the commentaries that Relational psychoanalysis has stood firmly against dichotomizing clinical reflection, on one hand, and interactional processes, on the other. Still, we wonder whether the relational literature has skewed toward interaction at the expense of concentrated attention to patients’ internal worlds. Predispositions toward interaction may diminish reflective space and quiet inwardness, which are themselves forms of analytic relating. We raise the possibility that the Relational model’s inclusive breadth, valuable as it is, might sometimes impede and even devalue discussions of specific technical matters. We consider clinical conceptualizations of ritual, “relating,” and “being in contact.”
