Parent–Child Interaction Therapy and Chronic Illness: A Case Study

We examined the outcome of parent–child interaction therapy (PCIT) for a child diagnosed with Oppositional Defiant Disorder (ODD) and cancer. Robert, a 4-year-old Caucasian male, showed significant and meaningful changes in his behavior over the course of 13 weeks of PCIT, and Robert no longer met diagnostic criteria for ODD following treatment. His scores on the Eyberg Child Behavior Inventory and the Achenbach Child Behavior Checklist were in the clinical range before treatment and in the normal range at the conclusion of treatment. His mother also reported dramatic improvements in Robert's behavior during medical visits. Physician and social worker reports were consistent with her report. Such anecdotal data may have implications for the generalization of compliance to the medical setting for children with chronic illnesses. The results of this case study should prompt further investigation of parent-training interventions for children with chronic illnesses and disruptive behavior.     

Retrieval-induced forgetting in perceptually driven memory tests

Recent data (T. J. Perfect, C. J. A. Moulin, M. A. Conway, & E. Perry, 2002) have suggested that retrieval-induced forgetting (RIF) depends on conceptual memory because the effect is not found in perceptually driven tasks. In 3 experiments, the authors aimed to show that the presence of RIF depends on whether the procedure induces appropriate transfer between representations and competition rather than on the nature of the final test. The authors adapted the standard paradigm to introduce lexical categories (words that shared the first 2 letters) at study and practice. Direct and indirect fragment completion tests were used at retrieval. The results showed significant RIF effects in perceptually driven tasks. Furthermore, they indicated that the presence of RIF effects depended on using adequate cuing to induce competition during the retrieval practice and on the final memory test tapping the inhibited representation.     

Different types of environmental enrichment have discrepant effects on spatial memory and synaptophysin levels in female mice

Environmental enrichment paradigms that incorporate cognitive stimulation, exercise, and motor learning benefit memory and synaptic plasticity across the rodent lifespan. However, the contribution each individual element of the enriched environment makes to enhancing memory and synaptic plasticity has yet to be delineated. Therefore, the current study tested the effects of three of these elements on memory and synaptic protein levels. Young female C57BL/6 mice were given 3h of daily exposure to either rodent toys (cognitive stimulation) or running wheels (exercise), or daily acrobatic training for 6 weeks prior to and throughout behavioral testing. Controls were group housed, but did not receive enrichment. Spatial working and reference memory were tested in a water-escape motivated radial arm maze. Levels of the presynaptic protein synaptophysin were then measured in frontoparietal cortex, hippocampus, striatum, and cerebellum. Exercise, but not cognitive stimulation or acrobat training, improved spatial working memory relative to controls, despite the fact that both exercise and cognitive stimulation increased synaptophysin levels in the neocortex and hippocampus. These data suggest that exercise alone is sufficient to improve working memory, and that enrichment-induced increases in synaptophysin levels may not be sufficient to improve working memory in young females. Spatial reference memory was unaffected by enrichment. Acrobat training had no effect on memory or synaptophysin levels, suggesting a minimal contribution of motor learning to the mnemonic and neuronal benefits of enrichment. These results provide the first evidence that different elements of the enriched environment have markedly distinct effects on spatial memory and synaptic alterations.     

Community violence, family conflict, and preschoolers' socioemotional functioning

This study examined the relations among family conflict, community violence, and young children's socioemotional functioning and explored how children's social cognition and mothers' psychological functioning may mediate the outcomes associated with this exposure. Mothers of 431 Head Start preschoolers completed questionnaires about their family demography, exposure to community violence, family conflict, and children's distress symptoms. Children were administered a social cognition assessment, and teachers rated their behavior. Results showed that mothers' reports of children's co-witnessing of community violence were positively associated with police department crime rates, children's distress symptoms, and teachers' ratings of aggression. A path analysis revealed that children's social awareness and mothers' depressive symptoms partially mediated the effects of community violence and family conflict on outcomes for children.     

3-D bone models to improve treatment initiation among patients with osteoporosis: A randomised controlled pilot trial

Objective: To investigate the efficacy of 3-D printed bone models as a tool to facilitate initiation of bisphosphonate treatment among individuals who were newly diagnosed with osteoporosis.

Design: Fifty eight participants with estimated fracture risk above that at which guidelines recommend pharmacological intervention were randomised to receive either a standard physician interview or an interview augmented by the presentation of 3-D bone models.

Main outcome measures: Participants’ beliefs about osteoporosis and bisphosphonate treatment, initiation of bisphosphonate therapy assessed at two months using self-report and pharmacy dispensing data.

Results: Individuals in the 3-D bone model intervention condition were more emotionally affected by osteoporosis immediately after the interview (p = .04) and reported a greater understanding of osteoporosis at follow-up (p = .04), than the control group. While a greater proportion of the intervention group initiated an oral bisphosphonate regimen (alendronate) (52%) in comparison with the control group (21%), the overall initiation of medication for osteoporosis, including infusion (zoledronate), did not differ significantly (intervention group 62%, control group 45%, p = .19).

Conclusion: The presentation of 3-D bone models during a medical consultation can modify cognitive and emotional representations relevant to treatment initiation among people with osteoporosis and might facilitate commencement of bisphosphonate treatment.     

Validation of the Ambivalent and Purposeful Engagement – Trait Measure

The Ambivalent and Purposeful Engagement-Trait Measure (APE-TM) was developed to assess two ways that people may react to stressful social interactions: ambivalent engagement (AE: counterproductive attempts to avoid thoughts and feelings) and purposeful engagement (PE: effortfully approaching and working through thoughts and feelings). We carried out three studies in undergraduate and clinical populations to (i) test the robustness of previous psychometric findings and (ii) determine whether AE and PE are specific to social anxiety. Across three studies, our results indicate that the APE-TM is a psychometrically valid measure of ambivalent and purposeful engagement. However, PE appeared less specific to social anxiety and may represent a more general tendency toward adaptive coping. In contrast, AE was specific to social anxiety in both undergraduate samples and clinical samples of individuals with a variety of anxiety disorders and depression.     

Free-association norms for the Spanish names of the Snodgrass and Vanderwart pictures

The most frequent names in Spanish corresponding to a set of 247 pictures in the Snodgrass and Vanderwart (1980) norms were used as stimuli in a discrete free-association task. A sample of 525 Spanish-speaking participants provided the first word that came to mind for each of the verbal stimuli. Responses were organized according to frequency of production in order to prepare word-association norms for the set of stimuli.
