本文报道了藻类游荡量表（AWS），一个28项的问卷，基于五个维度的游荡。通过因子分析，八个因子的解决方案解释了151名长期护理受试者评分的近70%的方差，并确认了三个结构维度。AWS的可靠性进行了内部一致性和评分者间的可靠性检查。AWS的α值为0.86;子尺度α值介于0.88（持续行走）和0.57（间歇行走）之间。评分员之间的可靠性，估计通过交叉评分员比较的AWS和分量表与四点判断徘徊状态，是中等强度和两组评分员之间没有显着差异。AWS及其分量表的有效性得到了支持，通过检查他们区分流浪者和非流浪者的能力，通过与认知障碍的测量和观察到的流浪的多个参数的正相关性，以及通过与非流浪运动的负相关性或无相关性。虽然AWS可能是一个有用的措施，徘徊在长期护理环境中，验证其因素结构和评估的跨文化样本是必要的。
This paper reports on the Algase wandering scale (AWS), a 28-item questionnaire, based on five dimensions of wandering. With factor analysis, an eight-factor solution explained nearly 70 percent of the variance in ratings for 151 long-term care subjects and confirmed three of the structuring dimensions. Reliability of the AWS was examined for internal consistency and for inter-rater reliability. The AWS had an alpha of .86; subscale alphas ranged between .88 (persistent walking) and .57 (routinized walking). Inter-rater reliabilities, estimated through cross-rater comparisons of the AWS and subscales with a four-point judgement of wandering status, were moderately strong and no significant differences existed between two sets of raters. Validity of the AWS and its subscales was supported by examining their ability to differentiate wanderers and nonwanderers, by positive correlation with measures of cognitive impairment and with multiple parameters of observed wandering, and by negative or no correlations with nonwandering locomotion. Although the AWS may be a useful measure of wandering in long-term care settings, validation of its factor structure and evaluation in cross-cultural samples is needed.
