Assessing the effectiveness of drawing an autobiographical memory as a mood induction procedure in children

The objective of our study was to examine the effectiveness of a new version of the autobiographical recall procedure (i.e., drawing a happy personal event) in eliciting a positive mood in 6-, 8-, and 10-year-old children and to compare the drawing condition to the more classical telling condition. The mood of children was assessed before and after induction using the Self-Assessment Manikin (SAM) and across the two emotional dimensions of valence and arousal. The results showed that the drawing condition was as effective as the telling condition for inducing a positive mood. Furthermore, in the drawing condition, children reported feeling calmer than in the telling condition, suggesting that drawing was more likely to help children regulate their emotional state. The drawing procedure could be used in future research aiming to induce positive moods in school-aged children, to help further investigate the relationship between cognition and emotion.     

The relationship between sleep and working memory in children with neurological conditions

The objective of this study is to investigate whether sleep problems might account for the increased working memory deficits observed in school-aged children with neurological conditions. A novel, transdiagnostic approach to the investigation was chosen, and sleep is treated as a process that can potentially account for working memory difficulties across a range of neurological conditions. Prevalence estimates of sleep problems are also examined. Archival data of 237 children aged 6 to 11 years were collected from a Western Australian statewide neuropsychological service for the period 26 July 2011 to 14 January 2014. Measures of parent-reported sleep quality, snoring, and daytime sleepiness were obtained, in addition to objective measures of verbal and spatial working memory, storage capacity, and processing speed. The results of the data analysis reveal that over one third of participants reported having clinically-significant levels of sleep problems and that poor sleep quality is significantly associated with verbal working memory difficulties. This association remains after partialling out the variance contributed to performance by storage capacity and processing speed, suggesting that sleep is impacting upon an executive component of working memory. No other significant associations are observed. The results suggest that poor sleep quality is associated with an executive component of verbal (rather than spatial) working memory in children with neurological conditions. This has implications for the biological mechanisms thought to underlie the relationship between sleep and cognition in children. The results also demonstrate the clinical utility of a transdiagnostic approach when investigating sleep and cognition in children with neurological conditions.     

The relationship between sleep problems and working memory in children born very preterm

In two studies, the relationship between sleep and working memory performance was investigated in children born very preterm (i.e., gestation less than 32 weeks) and the possible mechanisms underlying this relationship. In Study 1, parent-reported measures of snoring, night-time sleep quality, and daytime sleepiness were collected on 89 children born very preterm aged 6 to 7 years. The children completed a verbal working memory task, as well as measures of processing speed and verbal storage capacity. Night-time sleep quality was found to be associated with verbal working memory performance over and above the variance associated with individual differences in processing speed and storage capacity, suggesting that poor sleep may have an impact on the executive component of working memory. Snoring and daytime sleepiness were not found to be associated with working memory performance. Study 2 introduced a direct measure of executive functioning and examined whether sleep problems would differentially impact the executive functioning of children born very preterm relative to children born to term. Parent-reported sleep problems were collected on 43 children born very preterm and 48 children born to term (aged 6 to 9 years). Problematic sleep was found to adversely impact executive functioning in the very preterm group, while no effect of sleep was found in the control group. These findings implicate executive dysfunction as a possible mechanism by which problematic sleep adversely impacts upon cognition in children born very preterm, and suggest that sleep problems can increase the cognitive vulnerability already experienced by many of these children.     

Longitudinal Analysis of Particulate Air Pollutants and Adolescent Delinquent Behavior in Southern California

Animal experiments and cross-sectional human studies have linked particulate matter (PM) with increased behavioral problems. We conducted a longitudinal study to examine whether the trajectories of delinquent behavior are affected by PM_2.5 (PM with aerodynamic diameter?≤?2.5 μm) exposures before and during adolescence. We used the parent-reported Child Behavior Checklist at age 9–18 with repeated measures every ~2–3 years (up to 4 behavioral assessments) on 682 children from the Risk Factors for Antisocial Behavior Study conducted in a multi-ethnic cohort of twins born in 1990–1995. Based on prospectively-collected residential addresses and a spatiotemporal model of ambient air concentrations in Southern California, monthly PM_2.5 estimates were aggregated to represent long-term (1-, 2-, 3-year average) exposures preceding baseline and cumulative average exposure until the last assessment. Multilevel mixed-effects models were used to examine the association between PM_2.5 exposure and individual trajectories of delinquent behavior, adjusting for within-family/within-individual correlations and potential confounders. We also examined whether psychosocial factors modified this association. The results sμggest that PM_2.5 exposure at baseline and cumulative exposure during follow-up was significantly associated (p?<?0.05) with increased delinquent behavior. The estimated effect sizes (per interquartile increase of PM_2.5 by 3.12–5.18 μg/m³) were equivalent to the difference in delinquency scores between adolescents who are 3.5–4 years apart in age. The adverse effect was stronger in families with unfavorable parent-to-child relationships, increased parental stress or maternal depressive symptoms. Overall, these findings sμggest long-term PM_2.5 exposure may increase delinquent behavior of urban-dwelling adolescents, with the resulting neurotoxic effect aggravated by psychosocial adversities.     

Professionalism: A Competency Cluster Whose Time Has Come

Despite the burgeoning literature on professionalism in other health professions, psychology lags behind in the level of attention given to this core competency. In this article, we review definitions from other health professions and how they address professionalism. Next, we review how this competency evolved within health service psychology (HSP), and we propose a definition. We offer an approach for assessing professionalism within HSP. Consideration is given to strategies and methods for providing effective education and training in this multifaceted competency. Finally, recommendations are made for creating a culture of professionalism within HSP and honoring psychology’s social contract with multiple publics.     

Trainees with Competence Problems in the Professionalism Domain

Increasingly, professionalism has been recognized as a core competency for health service professionals and is the domain in which vexing competence problems are observed in trainees. We begin by describing manifestations of problems of professionalism in accord with the values that fall within the rubric of this multifaceted construct. We provide an approach for evaluating problems of professionalism and discuss intervention for trainees with mild, moderate, or severe problems in this domain. We propose implications for training focused on enhancing the culture of programs; bolstering the education, guidance, and mentoring provided related to professionalism; and encouraging best practices for addressing trainees with problems of professionalism. We conclude by sharing ideas about defining professionalism, identifying problems of professionalism, strengthening our approach to assessing professionalism and intervening when problems are evident, developing strategies for preventing professionalism problems, and ensuring that psychologists take seriously their responsibility to address professionalism concerns with colleagues.     

Immigrant Families’ Perception of the Causes,First Manifestations,and Treatment of Autism Spectrum Disorder

Compared to families from their host country, families from immigrant backgrounds who have a child with autism spectrum disorder (ASD) tend to experience greater difficulties in accessing, using, and complying with intervention services for their child. This disparity may be partially accounted for by cultural differences in how families perceive the causes and symptoms of ASD as well as their treatment priorities. The present study sought to document these perceptions in immigrant families living in a Canadian city. Forty-five parents from Latin America, Africa, Western and Eastern Europe, the Caribbean, East Asia, and the Middle East participated in a semi-structured interview. These data were examined qualitatively through thematic analysis to first document all parents’ perceptions, then to contrast mothers’ and fathers’ responses, and finally to examine common themes as a function of country of origin. The most frequently mentioned causes of ASD were environmental factors such as vaccines and diet. Moreover, some participants did not know the cause of their child’s ASD. The majority of parents cited the absence of speech as one of the first symptoms noted in their child. Priorities for intervention varied: mothers tended to prioritize speech therapy, whereas fathers favored support in school. Taken as a whole, these findings highlight the need to implement informational programs for these families.     

Psychosocial Impact of a Positive Gene Result for Asymptomatic Relatives at Risk of Hypertrophic Cardiomyopathy

Families with a history of hypertrophic cardiomyopathy (HCM) may be offered genetic testing in addition to clinical surveillance. Asymptomatic family members who are gene positive (silent gene carriers) represent a new group of “patients” who may not develop HCM, with little evidence available to assist clinical management. This study explored experiences of HCM genetic testing to identify potential benefits and harms. Thirty-two individuals previously offered genetic testing for HCM were recruited. Semi-structured interviews were conducted face-to-face or by phone, and transcribed audio-recordings were coded using framework analysis. Key themes were as follows: (1) helping the next generation, (2) misunderstanding risk, (3) discrepancy between actual/perceived impact. Participants described multiple psychological (shock, worry, uncertainty) and behavioural (career, sport, insurance, family planning) consequences, depending on perceived risk. Most considered only the benefits of genetic testing for children or grandchildren, but there were some cases of significant adverse impact. The interpretation of the HCM genetic test result is variable for silent gene carriers and can lead to psychological and behavioural changes. The impact of a positive gene result may be mitigated by increased clarity of the clinical consequences and efforts to ensure informed decision-making, highlighting even further the important role of cardiac genetic counselling.
