Age differences in interpreting ambiguous situations: the effects of content themes and depressed mood

Objectives: This study aimed to investigate the boundary conditions of the positivity effect on appraisals of ambiguous situations across content themes and emotional states. We differentiated the processes of interpretation generation and selection to see whether older adults recognize negative aspects of ambiguous situations but tend to select positive interpretations. Method: Seventy-six younger and 67 older adults went through sad and neutral mood inductions and completed ambiguous situation tasks. Participants were asked to generate interpretations and select one as the most likely explanation for each scenario. Results: Results demonstrated that compared with younger adults, older adults selected less negative interpretations across content themes but generated fewer negative interpretations in interpersonal but not in health situations. Depressed mood led to more negative interpretations at both generation and selection for younger adults but not older adults. Conclusions: Our results showed that thematic factors had an effect on the positivity effect on interpretation generation, but regardless of content themes, older adults selected a less negative interpretation as the most likely, despite knowing alternative negative explanations. The positivity effect remained for older adults in high trait and state depressed mood. Together these findings are consistent with the pattern of older adults’ tendency to maximize emotional well-being through less negative interpretations of ambiguous situations

Can we do better? Researchers' experiences with ethical review boards on projects with later life as a focus

The goal of this study was to describe researchers' experiences in submitting ethical proposals focused on older adult populations, including studies with persons with dementia, to ethical review boards. Ethical approval was granted for an online survey. Researchers were recruited via listservs and snowballing techniques. Participants included 157 persons (73% female) from Australia and the United States, with a mean age of 46 (±13). Six main issues were encountered by researchers who participated in this survey. In descending order, these included questions regarding: informed consent and information requirements (61.1%), participants' vulnerability, particularly for those with cognitive impairments (58.6%), participant burden (44.6%), data access (29.3%), adverse effects of data collection/intervention (26.8%), and study methodology (25.5%). An inductive content analysis of responses revealed a range of encounters with ethical review panels spanning positive, negative, and neutral experiences. Concerns voiced about ethical review boards included committees being overly focused on legal risk, as well as not always hearing the voice of older research participants, both potential and actual. Respondents noted inability to move forward on studies, as well as loss of researchers and participant groups from gerontological and clinical research as a result of negative interactions with ethics committees. Positive interactions with the committees reinforced researchers' need to carefully construct their research approaches with persons with dementia in particular. Suggested guidelines for committees when dealing with ethics applications involving older adults include self-reflecting on potential biases and stereotypes, and seeking further clarification and information from gerontological researchers before arriving at decisions

Understanding the Mechanisms of Change in a Lifestyle Intervention for Older Adults

Purpose of the Study: This study investigated the mechanisms of change underlying an activity-based lifestyle intervention, an occupational therapy program aimed at promoting healthy habits, and routines in older adults. We examined two activity-relevant factors as potential mediators linking the intervention to reduced symptoms of depression: activity frequency and global perceptions of activity significance. Social connections and perceived control were assessed to understand how activity-related factors relate to reduced symptoms of depression. Design and Methods: The sample consisted of 460 multiethnic community-dwelling older adults aged 60–95 years. Participants were randomly assigned to a 6-month lifestyle redesign intervention (n = 232) or a no-treatment control (n = 228) condition. After the 6-month period, 360 individuals completed post-testing. Latent change score models were used to represent changes from baseline over the experimental interval. Structural equation models were applied to examine the indirect effects of the intervention on reduced depressive symptoms. Results: The results demonstrated significant indirect effects from intervention receipt to decreased depressive symptoms via increased activity frequency and activity significance. Higher activity frequency was linked to fewer depressive symptoms via heightened social connections, whereas increased activity significance was associated with fewer depressive symptoms via enhanced perceived control. Implications: The results support basic principles of occupational therapy by highlighting important mediating roles of activity frequency and activity significance in reducing depressive symptoms. Understanding of these change mechanisms can help optimize activity-centered interventions to reduce depressive symptoms

Comparison of diagnostic imaging modalities for the evaluation of pancreatic duct injury in children: a multi-institutional analysis from the Pancreatic Trauma Study Group

© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. Purpose: Determining the integrity of the pancreatic duct is important in high-grade pancreatic trauma to guide decision making for operative vs non-operative management. Computed tomography (CT) is generally an inadequate study for this purpose, and magnetic resonance cholangiopancreatography (MRCP) is sometimes obtained to gain additional information regarding the duct. The purpose of this multi-institutional study was to directly compare the results from CT and MRCP for evaluating pancreatic duct disruption in children with these rare injuries. Methods: Retrospective study of data obtained from eleven pediatric trauma centers from 2010 to 2015. Children up to age 18 with suspected blunt pancreatic duct injury who had both CT and MRCP within 1 week of injury were included. Imaging findings of both studies were directly compared and analyzed using descriptive statistics, Chi square, Wilcoxon rank-sum, and McNemar’s tests. Results: Data were collected for 21 patients (mean age 7.8 years). The duct was visualized more often on MRCP than CT (48 vs 5%, p \u3c 0.05). Duct disruption was confirmed more often on MRCP than CT (24 vs 0%), suspected based on secondary findings equally (38 vs 38%), and more often indeterminate on CT (62 vs 38%). Overall, MRCP was not superior to CT for determining duct integrity (62 vs 38%, p = 0.28). Conclusions: In children with blunt pancreatic injury, MRCP is more useful than CT for identifying the pancreatic duct but may not be superior for confirmation of duct integrity. Endoscopic retrograde cholangiogram (ERCP) may be necessary to confirm duct disruption when considering pancreatic resection. Level of evidence: III
