To evaluate the validity and reliability of a cognitive test battery and questionnaires administered by telephone.
Observational study; 110 participants randomly assigned to receive two administrations of the same cognitive test battery 6 months apart in one of four combinations (Time 1 administration/Time 2 administration): telephone/telephone, telephone/face to face, face to face/telephone, face to face/face to face.
Academic medical center.
One hundred ten women aged 65 to 90 without dementia.
The battery included tests of attention; verbal learning and memory; verbal fluency; executive function; working memory; global cognitive functioning; and self-reported measures of perceived memory problems, depressive symptoms, sleep disturbance, and health-related quality of life. Test-retest reliability, concurrent validity, relative bias associated with telephone administration, and change scores were evaluated.
There were no statistically significant differences in scores on any of the cognitive tests or questionnaires between participants randomly assigned to telephone or face-to-face administration at the Time 1 assessment, indicating equivalence across administration modes. There was no significant bias for tests or questionnaires administered by telephone (P's > .01), nor was there a difference in mean change scores between administration modes except for Category Fluency (P = .01) and California Verbal Learning Test long-delay free recall (P = .004). Mean test-retest coefficients for the battery were not significantly different between groups, although individual test-retest correlation coefficients were generally higher within modes than between modes.
Telephone administration of cognitive tests and questionnaires to older women is reliable and valid. Use of telephone batteries can substantially reduce the cost and burden of cognitive assessments and increase enrollment, retention, and data completeness, thereby improving study validity.
评估通过电话进行的认知测试组合和问卷的有效性和可靠性。
观察性研究；110 名参与者随机分为四组中的两组，在 6 个月的时间内接受相同认知测试组合的两次测试（第 1 次测试/第 2 次测试）：电话/电话、电话/面对面、面对面/电话、面对面/面对面。
学术医疗中心。
110 名年龄在 65 至 90 岁之间、无痴呆的女性。
测试组合包括注意力测试、语言学习和记忆测试、语言流畅性测试、执行功能测试、工作记忆测试、总体认知功能测试，以及自我报告的记忆问题、抑郁症状、睡眠障碍和与健康相关的生活质量感知的测试。评估了测试-重测信度、同期有效性、与电话管理相关的相对偏差和变化分数。
在第 1 次评估中，随机分配到电话或面对面管理的参与者在任何认知测试或问卷上的得分均无统计学差异，表明管理模式之间具有等效性。通过电话管理的测试或问卷没有明显的偏差（P 值均>.01），除了类别流畅性（P =.01）和加利福尼亚语言学习测试长延迟自由回忆（P =.004）外，管理模式之间的平均变化分数也没有差异。尽管个体测试-重测相关系数在模式内通常高于模式间，但电池的平均测试-重测系数在组间没有显著差异。
对老年女性进行电话管理的认知测试和问卷是可靠和有效的。使用电话电池可以大大降低认知评估的成本和负担，并增加入组、保留和数据完整性，从而提高研究的有效性。
