简要总结
Multiple sclerosis (MS) is among the most prevalent autoimmune diseases among young and middle-aged adults. Up to 65% of MS patients experience objective cognitive impairment including problems with information processing speed, memory, and executive functioning. However, patients commonly overestimate the extent of their cognitive dysfunction which can result in inaccurate perceptions of their true cognitive abilities. Exaggerated perceptions of cognitive impairment are predictive of future decline and associated with depression, anxiety, and reduced quality of life. Despite this, no study has examined an intervention aimed at changing misperceptions related to perceived cognitive impairment in MS when objective measures are incongruent with self-reported cognitive symptoms. The purpose of the present study is to develop and pilot a brief intervention for MS patients who perceive cognitive impairment, but perform in the normal or expected range on objective measures of cognition.
详细描述
Concern over worsening cognitive functioning has been shown to significantly impact patients' lives. More than half of all MS patients demonstrate clinically significant cognitive dysfunction, making it one of the leading causes of disability in MS. Cognitive deficits often manifest in areas associated with information processing speed, memory, and executive functioning. Resulting sequela can have profound implications on employment, interpersonal relationships, and activities of daily living. Despite the prevalence of cognitive dysfunction in MS, most studies find little to no relationship between perceived and objective cognition in MS. Research shows that some patients overestimate the extent of their cognitive deficits. PCI is associated with poor self-efficacy, social, and occupational difficulties. Evidence suggests that negative emotional states may contribute to overestimated PCI in MS. Exaggerated perceptions of impaired cognition may be intensified by the presence of other MS symptoms, which can affect the way patients report disease activity to healthcare providers and complicate detection of relevant disease symptomatology.
Overestimating cognitive impairment has been observed in other patient populations, but it is especially problematic in MS and can provide an opportunity to inform patients about discrepancies between perceived and objective cognitive functioning. Since physicians spend significant amounts of time negating unsubstantiated healthcare concerns, an intervention aimed at decreasing PCI in MS may improve long-term healthcare outcomes as well as the quality of time that physicians spend with patients. Neuropsychological test results can be used as objective evidence against perceived cognitive impairment to change patients perceptions, if conveyed in an appropriate and nonthreatening manner.
Educating patients about the influence of emotional dysfunction and misattribution as it relates to PCI may also decrease concern regarding cognitive decline and MS. Specifically, internal processes such as emotional dysfunction, including a globally negative world view can increase dissociative experiences that cause patients to misattribute normal cognitive errors as MS-related cognitive decline. This model may inform patients understanding of medically unsubstantiated PCI, allowing them to consider alternative factors associated with common cognitive errors aside from MS.
Although many studies have aimed to improve cognition in MS through pharmacological treatments, cognitive rehabilitation, and psychotherapy, to the investigators knowledge, this is the first study to examine a psychoeducational intervention to decrease exaggerated perceptions of cognitive impairment in MS. For the present study, the investigators will develop a brief computer-based intervention for MS patients who perceive cognitive decline incongruent with objective measures of cognition. The proposed intervention will incorporate feedback from neuropsychological tests, including comparisons of perceived and objective performance. The intervention will also introduce psychoeducation about causes of PCI, such as emotional distress, attention, and misattribution. It is hoped that by combining neuropsychological test feedback and psychoeducation, patients may better understand differences between perceived and objective cognition, which in turn, may reduce concern and offer alternative explanations for PCI.

盲法说明
2, 4, and 6 blocked randomization (by gender) was conducted via computer generator. Group assignment was specified and sealed in individual envelopes by a study coordinator who is not involved in the current project. After participants are enrolled and complete the baseline evaluation, the appropriate envelope will be selected, based on gender, containing group assignment, and the subsequent intervention will be administered. Group assignment is not established until after the baseline evaluation has been conducted. Determining randomization will take place at a separate location from the recruitment/baseline site. No study member will have direct contact with participants following the baseline evaluation since the intervention is computerized and replies on emailing the study link to complete the intervention.

结局指标
主要结局
Feasibility and Acceptability Questionnaire
时间窗: 5 minutes
All participants complete a feasibility and acceptability questionnaire upon study completion. The questionnaire will address satisfaction with study participation, effectiveness and convenience of the intervention, and short answer questions on newly acquired information, application of information learned, and feelings about the new information. Participants will also be asked if they perceived the intervention as helpful and if they would be willing to recommend it to other MS patients. This measure will be scored quantitatively, ranging from 0-85 possible points, where higher scores indicated greater feasibility and acceptability of the intervention.
