Health Behaviors of Childhood Cancer Survivors: What We’ve Learned

There has been a dramatic increase in the number of childhood cancer survivors due to improved cancer treatments. However, these survivors are at risk for numerous late-effects as a result of their cancer therapy. Engaging in health-protective behaviors and limiting risky health behaviors are vitally important for survivors given their increased risks and physical late-effects. For this paper, we systematically reviewed the literature on childhood cancer survivors’ health behaviors by searching for published data and conference proceedings using computerized databases and references, and summarized these results. We examined the literature describing the prevalence of a variety of health behaviors among survivors, identifying significant covariates, and describing health behavior interventions. Finally, we provided research recommendations and discussed an ongoing study designed to address some of the limitations in the existing literature. The research to date is limited and recommendations for future studies are outlined.     

Hippocampus function predicts severity of post-traumatic stress disorder.

Post-traumatic stress disorder (PTSD) is often accompanied by memory problems and abnormal brain structure, particularly within the hippocampus. We implemented a cross-species, hippocampal-dependent task--the virtual Morris Water task--to assess hippocampal function in people with PTSD and age-matched controls during functional magnetic resonance imaging (fMRI). Performance on the task was equivalent between the groups. However, when correlating fMRI-derived hippocampal activity during this task with PTSD severity, we observe a -0.84 correlation, indicating that those with reduced hippocampal activity show more severe PTSD symptoms. This correlation is not explained by differences in task performance, IQ, duration since trauma, nor time with PTSD. Hence, PTSD severity is predicted by functionally assessing the hippocampus using the virtual Morris water task, suggesting that this task may be used to identify those at risk for developing PTSD following a trauma.     

Finding the good in the bad: age and event experience relate to the focus on positive aspects of a negative event

All lives contain negative events, but how we think about these events differs across individuals; negative events often include positive details that can be remembered alongside the negative, and the ability to maintain both representations may be beneficial. In a survey examining emotional responses to the 2013 Boston Marathon bombings, the current study investigated how this ability shifts as a function of age and individual differences in initial experience of the event. Specifically, this study examined how emotional importance (i.e. self-reported emotional arousal and personal significance), involvement (i.e. self and friend/family involvement in the 2013 Boston Marathon and self-involvement in prior marathons), and self-reported surprise upon hearing about the event related to the tendency to report focusing on the negative and positive aspects of the bombings. Structural equation models revealed that while greater emotional importance and surprise were associated with a greater focus on negative elements, involvement and age were associated with increased consideration of positive aspects. Further, emotional importance was more strongly related to an increased focus on negative aspects for young adults and an increased focus on positive aspects for older adults, highlighting a tendency for older adults to enhance positive features of an otherwise highly negative event.     

Increasing Behavioral Variability and Social Skill Accuracy in Children with Autism Spectrum Disorder

Although social skills training for children with autism spectrum disorder (ASD) often addresses deficits in social communication, restricted and repetitive social behaviors are less frequently targeted in the literature. The present study evaluated a manualized social skills training program, modified to incorporate lag schedules of reinforcement, to promote appropriate and variable responding in three children in a school setting. Participants attended social skills once weekly, with probes of social skills taking place daily. A multiple baseline design across target skills was used to determine intervention efficacy. Results of the study indicated that the social skills curriculum incorporating lag schedules of reinforcement resulted in substantial increases in the number of appropriate and variable responses demonstrated by participants during each probe session, as well as the number of appropriate and variable responses demonstrated overall.     

Theology and Religious Studies at the Turn of the Millenium: Reconceiving the Field

This article originated as a lecture at the celebration of 150 years of the Department of Theology and Religious Studies in King's College of the University of London. Professor Ford argues that our good practice as teachers has outstripped any available paradigm of the field, so it is necessary to reconceive it. He proposes four dimensions that unite theological and religious studies: how to study the phenomena of religions; how to establish norms and responsibilities; how to cope with radical, self-involving particularity; and how to involve the divine in academic studies.
