Can Peer Assessment Impact Self-efficacy During Small-Group Learning?

INTRODUCTION: While studies report positive correlations between students' perceptions of the learning environment and their reported self-efficacy, the role of peer assessment is poorly understood in this context. This study examines the process and impact of peer assessment on self-efficacy and perceptions of the learning environment during a small-group discussion-based course required of first-year medical students. METHODS: After spending time in small-group learning, students completed three peer assessments and reviewed three assessments of themselves. Analysis of the peer assessments included thematic coding of comments and word counts. Prior to and following the assessment period, students completed a survey including the Generalized Self-efficacy (GSE) Scale, and six locally-developed questions regarding the learning environment and perceptions of peer assessment. We performed paired-sample t tests to determine whether there were differences between the pre- and post-peer assessment surveys. The SUNY Upstate Institutional Review Board reviewed the study and determined it to be exempt. RESULTS: Peer assessment narratives referred most commonly to students' participation style and the need for greater participation. Word counts ranged widely. A paired sample t test indicated that the difference between pre and post peer assessment GSE scores was significant (P=.009), but the effect size was small (d=0.32). Perceptions of the learning environment did not change after the peer assessments. CONCLUSION: Peer assessment offers a potential strategy for enhancing self-efficacy in medical school small-group learning environments and requires few resources to implement, relative to the potential benefits.

"The stakes could not be higher": A mixed methods study of parental social media use in pediatric oncology.

BACKGROUND: To describe how parents and families of children with cancer evaluate the benefits and risks of using social media (SM) and how they navigate disagreements between oncologists' advice and information found on SM. PROCEDURE: Parents of children who had been previously diagnosed with cancer, and who had used SM for a purpose related to that child's health were recruited through SM sites and nonprofit organizations across the United States and were invited to complete questionnaires about their experiences using SM; a subset of participants also completed a follow-up in-depth interview. Open-ended responses and interviews were analyzed using thematic analysis. RESULTS: Ninety parents completed written questionnaires; 21 completed follow-up interviews. Seventy percent reported experiencing a situation in which information shared on SM conflicted with information provided by their child's oncologist. Although 86% reported that they discussed the conflicting information with the oncologist and 70% described the oncologist's response as positive, 78% also described ongoing negative feelings about the experience. Parents described openness to discussing SM, honesty, transparency, and humility regarding the limits of medicine, and shared decision-making regarding information found on SM as increasing their trust in their oncologist. CONCLUSIONS: Parents offered valuable insights regarding their experiences navigating SM, including eight recommendations for how pediatricians might approach discussing parental SM use. Future studies will evaluate the utility of these recommendations for pediatric clinicians.

Qualitative insights into how men with low-risk prostate cancer choosing active surveillance negotiate stress and uncertainty.

BACKGROUND: Active surveillance is a management strategy for men diagnosed with early-stage, low-risk prostate cancer in which their cancer is monitored and treatment is delayed. This study investigated the primary coping mechanisms for men following the active surveillance treatment plan, with a specific focus on how these men interact with their social network as they negotiate the stress and uncertainty of their diagnosis and treatment approach. METHODS: Thematic analysis of semi-structured interviews at two academic institutions located in the northeastern US. Participants include 15 men diagnosed with low-risk prostate cancer following active surveillance. RESULTS: The decision to follow active surveillance reflects the desire to avoid potentially life-altering side effects associated with active treatment options. Men on active surveillance cope with their prostate cancer diagnosis by both maintaining a sense of control over their daily lives, as well as relying on the support provided them by their social networks and the medical community. Social networks support men on active surveillance by encouraging lifestyle changes and serving as a resource to discuss and ease cancer-related stress. CONCLUSIONS: Support systems for men with low-risk prostate cancer do not always interface directly with the medical community. Spousal and social support play important roles in helping men understand and accept their prostate cancer diagnosis and chosen care plan. It may be beneficial to highlight the role of social support in interventions targeting the psychosocial health of men on active surveillance.

Cognitive and Affective Representations of Active Surveillance as a Treatment Option for Low-Risk Prostate Cancer.

Benefits of early diagnosis and treatment remain debatable for men with low-risk prostate cancer. Active surveillance (AS) is an alternative to treatment. The goal of AS is to identify patients whose cancer is progressing rapidly while avoiding treatment in the majority of patients. The purpose of this study was to explore cognitive and affective representations of AS within a clinical environment that promotes AS a viable option for men with low-risk prostate cancer. Participants included patients for whom AS and active treatment were equally viable options, as well as practitioners who were involved in consultations for prostate cancer. Data were generated from semistructured interviews and audits of consultation notes and were analyzed using thematic analysis. Nineteen patients and 16 practitioners completed a semistructured interview. Patients generally viewed AS as a temporary strategy that was largely equated with inaction. There was variation in the degree to which inaction was viewed as warranted or favorable. Patient perceptions of AS were generally malleable and able to be influenced by information from trusted sources. Encouraging slow deliberation and multiple consultations may facilitate greater understanding and acceptance of AS as a viable treatment option for low-risk prostate cancer.

Total inhibition of (1)O2-induced oxidative damage to guanine bases of DNA/RNA by turmeric extracts.

The guanine base of nucleic acids is known to be very reactive towards degradation by (1)O2-induced oxidative stress. Oxidative reactions of DNA are linked to many human diseases including cancer. Among the various forms of reactive O2 species (OH, (1)O2 or O2(-)), the oxidative stress caused by (1)O2 is of particular physiologic importance because of its selectively long life in aqueous medium and its ability to diffuse through a cell membrane. In this study we investigated the degradation of a model compound guanosine (Guo) by (1)O2, which was generated by riboflavin-induced photosensitization and by molybdate ion catalyzed disproportionation of H2O2. We observed the remarkable ability of an aqueous and alcoholic extracts of Turmeric (Curcuma longa) as an extraordinary scavenger of (1)O2 to completely inhibit the degradation of Guo. The alcoholic extracts were more effective in their antioxidant activity than the corresponding water extract. This naturally occurring antioxidant offers a most economical supplement to protect biologically significant molecules from the oxidative stress induced by (1)O2.
