Aim: Depression is common in older adults with vision impairment yet it often remains unidentified and untreated. Eye health professionals (EHPs) and rehabilitation workers (RWs) may be able to assist in detecting depression. This study identified EHPs' and RWs' beliefs about depression and confidence in working with patients with vision impairment and depression. Methods: A self‐administered cross‐sectional survey of 94 EHPs and RWs assessed beliefs about the symptoms and treatment for depression, and confidence in working with depressed people with vision impairment. Results: Participants showed awareness of both the symptoms and treatment options for depression. However, some important misconceptions were identified and many symptoms of depression were commonly attributed to vision loss. Participants lacked confidence in communicating about depression with patients and their families. Conclusions: Training programs are needed to enable EHPs and RWs to confidently identify depression and discuss appropriate treatment and referral options with their patients.  相似文献

During our time in the 2013 Academic Leadership Fellows Program, we explored what it takes to achieve life balance through a framework presented in a Harvard Business Review article. In this Statement, we describe 5 different areas from the article that provide infrastructure for reflecting on how we have learned to approach life balance in academia. We also provide brief messages based on this reading and others to help academics’ pursuit of life balance.  相似文献

Yerxa’s [1] model of an integrated profession depicts a circular scholarly process whereby ideas formed in practice are subjected to research and then returned to practice through education. This knowledge-generating cycle supports occupational science and the development of our professional identity. The aim of this article is to demonstrate how Yerxa’s model was used to evaluate if three developmental cycles of the ADL-Focused Occupation-Based Neurobehavioral Evaluation (A-ONE) sufficiently represented all necessary model components required for implementation into practice. The three cycles were historical, educational and measurement. The necessary components included: (a) dilemmas in practice, (b) new ideas that emerged from those practice issues, (c) research to test those ideas and (d) education designed to integrate new knowledge into practice. The results of this analysis of the A-ONE supported adequate research related to ideas from practice being implemented back into practice. Through using the model of an integrated profession to reflect on ideas ignited within practice, and then implementing research to explore the potential contribution of those ideas to knowledge generation, we gain the power to influence the future development of occupational science and the profession.  相似文献

ABSTRACT

For a nationwide Geriatric Interdisciplinary Team Training (GITT) program evaluation of 8 sites and 26 teams, team evaluators developed a quantitative and qualitative team observation scale (TOS), examining structure, process, and outcome, with specific focus on the training function. Qualitative data provided an important expansion of quantitative data, highlighting positive effects that were not statistically significant, such as role modeling and training occurring within the clinical team. Qualitative data could also identify “too much” of a coded variable, such as time spent in individual team members' assessments and treatment plans. As healthcare organizations have increasing demands for productivity and changing reimbursement, traditional models of teamwork, with large teams and structured meetings, may no longer be as functional as they once were. To meet these constraints and to train students in teamwork, teams of the future will have to make choices, from developing and setting specific models to increasing the use of information technology to create virtual teams. Both quantitative and qualitative data will be needed to evaluate these new types of teams and the important outcomes they produce.  相似文献

Cystic fibrosis (CF) results in increased energy requirements at rest. However, the energy expended during physiotherapy management is unknown. The aim of this study, therefore, is to examine the energy expended during two commonly used forms of chest physiotherapy in CF subjects. Twenty-six CF subjects completed a randomised crossover trial with 48 hours between treatments. Two regimens of treatment were conducted: therapist-assisted treatment (active cycle of breathing, ACBT, with percussion, vibration), and independent treatment (ACBT alone, under the supervision of a physiotherapist). Subjects completed pulmonary function tests before and after either treatment. Indirect calorimetry and oximetry parameters were recorded at rest, during, and following treatment. Treatment groups were compared using ANOVA and two-sample crossover t-tests. When compared to resting values, physiotherapy treatment resulted in significant increases in VO2, VCO2 and respiratory exchange ratio. No difference was evident between treatment regimens for the change in VO2 between baseline and treatment. The increase in ventilation (baseline to treatment) was significantly greater for the therapist-assisted treatment. The therapist-assisted ACBT was associated with a significant carryover effect for forced expiratory flow at 50% of vital capacity (FEF50). Oxygen requirements for the two treatments were similar. However, the assisted regimen resulted in greater changes in minute ventilation during treatment and improved 48-hour post-treatment pulmonary function after only one treatment session. These findings suggest that the inclusion of percussion and vibration within the ACBT may influence respiratory muscle activity during treatment and result in improved pulmonary function.  相似文献

Studies indicate that both preservice and in-service teachers find it difficult to connect to their role as health promoters within a school context. There is also evidence that those teachers most often responsible for delivering health education (i.e., physical education teachers) are at an increased risk for body dissatisfaction, dieting, and disordered eating. A pre–post pilot study assessed the feasibility and utility of an interactive professional development workshop on preservice teachers' attitudes concerning body image, size acceptance, eating, and physical activity, as well as the impact of the workshop on perceived self-efficacy to address weight-related issues. The professional development had a positive effect on antifat attitudes, body image, implicit weight bias, and efficacy to address weight issues. While the workshop was useful in terms of significant changes in preservice teachers' attitudes and efficacy, lessons around feasibility will inform the development of this pilot study to full-scale workshop with preservice teachers.  相似文献

This study analyzes the anthropometric and physiological characteristics of junior cyclists within different cycling specialties and different performance levels. One hundred and thirty‐two junior riders (16.8 ± 0.6 years, 177 ± 6 cm, 66.3 ± 6.7 kg) were tested for anthropometric, aerobic and anaerobic parameters. Cyclists were classified within specialties [uphill (UH) flat terrain (FT) all terrain (AT) and sprint (SP)] and performance levels, based on a seasonal ranking [low level (LL) medium level (ML) and high level (HL)]. The results of the two‐way analysis of variance showed that FT and SP have greater body dimensions than UH and AT (P<0.001). Concerning the relative aerobic parameters, AT and UH have higher values (P<0.001) than FT and SP [maximal oxygen uptake (VO2max): 69.4 ± 3.6, 67.5 ± 5.0, 62.8 ± 4.5 and 61.9 ± 4.1 mL/kg/min, respectively] while absolute parameters resulted higher for FT and AT (P≤0.008). The relative power produced in the 5 s test was higher (P<0.001) for AT and SP than FT and UH (16.7 ± 1.1, 16.6 ± 0.6, 14.9 ± 1.7 and 14.4 ± 1.7 W/kg, respectively). Concerning the performance level, only the age and the aerobic parameters resulted differently within levels (VO2max: HL=67.3 ± 4.9, ML=65.5 ± 5.1 and LL=63.3 ± 5.2 mL/kg/min), with the highest values for HL (P≤0.007). In conclusion, juniors are specialized in the same way as professional cyclists and the aerobic characteristics are confirmed as significant in the performance level assessment.  相似文献
