摘要
修改后的痴呆症忧虑量表(DWS)使用了术语“阿尔茨海默病及相关痴呆”(而DWS使用的是“痴呆”)。两项研究调查了改良DWS (MDWS)的心理测量特性。研究1比较了DWS和MDWS的心理测量特性;两种版本均具有单因素结构,具有良好的内部一致性(αs≥0.95)。MDWS在4周间隔后表现出更高的重测信度(DWS r = 0.68;MDWS r = 0.90)。在研究2中,MDWS再次表现出单因素结构,具有良好的内部一致性(α = 0.95), 8周间隔后具有良好的重测信度(r = 0.78)。此外,结果支持MDWS与痴呆恐惧、主观记忆、一般焦虑、健康焦虑和神经质之间的趋同效度。MDWS在心理计量学上与DWS一致,具有很强的重测信度,适用于横断面和纵向研究。
A 2-Study Psychometric Evaluation of the Modified Dementia Worry Scale.
A modified version of the Dementia Worry Scale (DWS) used the terminology "Alzheimer's disease and related dementias" (versus the DWS' use of "dementia"). Two studies investigated psychometric properties of the modified DWS (MDWS). Study 1 compared the psychometric properties of the DWS and MDWS; both versions had single factor structures and exhibited excellent internal consistency (αs ≥ .95). The MDWS exhibited greater test-retest reliability after a 4-week interval (DWS r = .68; MDWS r = .90). In Study 2, the MDWS again displayed a single factor structure, excellent internal consistency (α = .95), and good test-retest reliability after an 8-week interval (r = .78). Additionally, results support convergent validity between the MDWS and fear of dementia, subjective memory, general anxiety, health anxiety, and neuroticism. The MDWS is psychometrically consistent with the DWS, maintains strong test-retest reliability, and is appropriate for use in cross-sectional and longitudinal research.
