DESCRIPTION (provided by applicant): The primary aim of this career training proposal is to train Ava Kiser, O.D. to become a successful, independent clinician-scientist, capable of performing high-quality clinical research in low vision. This goal will be accomplished through a mentored research project and didactic coursework leading to a PhD degree in clinical investigation. Two types of mentors will be involved in the training plan, related to 1) psychological evaluations and mindfulness-based stress reduction interventions for those with chronic disease; and 2) clinical trials, including data analysis statistics, study design and methodology. Numerous institutional resources will also play a supporting role during this training program. The candidate's research goals include the conduct of clinical trials in low vision, potentially involving Complementary and Alternative Medicine (CAM) or other interventions in visually impaired patients.. Negative psychological states such as distress, anxiety and depression are common in retinitis pigmentosa (RP) due to the chronic, slowly progressive nature of this disabling disease. Psychophysical vision measures are more variable in legally blind RP subjects than in normally sighted individuals, and RP patients indicate that variations in vision are often related to stress or fatigue. Short term research aims are to determine whether within and between day fluctuations in visual acuity, contrast sensitivity and visual field among RP patients are associated with perceived stress, sleepiness or negative mood states. This will be accomplished with at home PC-based questionnaires and vision tests, self-administered by the subjects at various times of the day and days of the week. We will also assess the impact of light exposure, sleep, and lab-induced pychosocial stress upon vision tests, to establish a profile of the characteristics of the RP subjects with the most variable vision. The candidate's training will include a small clinical trial to attempt to alleviate these factors in RP patients with a mind-body, cognitive-behavioral stress reduction intervention versus a control eye exercise program. Sources for the variability of vision measurements during future treatment clinical trials need to be identified and addressed before results can be properly assessed. This research may indicate the value of CAM-related interventions, and thus potentially improve the reliability of vision tests as outcome measures during future clinical trials and the quality of life for RP patients.

描述（由申请人提供）：本职业培训提案的主要目的是培训 Ava Kiser，O.D.成为一名成功的、独立的临床医生科学家，能够在低视力方面进行高质量的临床研究。这一目标将通过指导研究项目和教学课程来实现，从而获得临床研究博士学位。培训计划将涉及两类导师，分别涉及：1）针对慢性病患者的心理评估和正念减压干预； 2）临床试验，包括数据分析统计、研究设计和方法。众多机构资源也将在本次培训中发挥支持作用。该候选人的研究目标包括开展低视力临床试验，可能涉及补充和替代医学（CAM）或对视障患者的其他干预措施。由于这种致残疾病的慢性、缓慢进展的性质，痛苦、焦虑和抑郁等负面心理状态在视网膜色素变性（RP）中很常见。与视力正常的人相比，法定失明的 RP 受试者的心理物理视力测量结果变化更大，并且 RP 患者表明视力的变化通常与压力或疲劳有关。短期研究的目的是确定 RP 患者的视力、对比敏感度和视野的日内和日间波动是否与感知压力、困倦或负面情绪状态相关。这将通过家庭基于电脑的问卷和视力测试来完成，由受试者在一天中的不同时间和一周中的不同日子自行进行。我们还将评估光照、睡眠和实验室引起的心理社会压力对视力测试的影响，以建立视力变化最大的 RP 受试者的特征概况。候选人的培训将包括一项小型临床试验，试图通过心身、认知行为减压干预与对照眼保健计划来减轻 RP 患者的这些因素。在正确评估结果之前，需要确定并解决未来治疗临床试验期间视力测量变异的来源。这项研究可能表明 CAM 相关干预措施的价值，从而有可能提高视力测试作为未来临床试验结果测量的可靠性以及 RP 患者的生活质量。
