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.

痴呆症焦虑量表（DWS）的修订版使用了“阿尔茨海默氏病和相关痴呆症”的术语（相对于DWS对“痴呆症”的使用）。两项研究调查了修改后的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，并具有出色的内部一致性（αs≥.95）。在间隔4周后，MDWS表现出更高的重测可靠性（DWS r = .68; MDWS r = .90）。在研究2中，MDWS再次显示出单因素结构，出色的内部一致性（α= .95）和8周间隔后的重测信度（r = .78）。此外，结果支持MDWS与痴呆症，主观记忆，全身性焦虑，健康焦虑和神经质性恐惧之间的聚合效度。
