Compensatory strategies (behavioral/environmental modifications) can reduce the difficulties of performing daily living activities, fear of falling, and mortality risk. However, individuals vary in their readiness to use strategies. We examined characteristics associated with readiness to use compensatory strategies, the extent to which level of readiness changed from participation in an intervention (Advancing Better Living for Elders (ABLE)) providing compensatory strategies, and factors predictive of change in readiness level.
Data from a randomized trial were used. Participants were 148 older adults assigned to the ABLE intervention designed to enhance daily function through compensatory strategy use. Baseline measures included demographic characteristics, functional difficulty level, presence/absence of depressive symptoms, compensatory strategy use, and social support. At initial (2 weeks from baseline) and final (6 months) ABLE sessions, interventionists rated readiness (1 = precontemplation; 2 = contemplation; 3 = preparation; 4 = action/maintenance) of participants to use strategies. Ordinal logistic regression was used to identify baseline characteristics associated with initial readiness rating. A McNemar-Bowker test of symmetry was used to describe change in readiness, and binary logistic regression was used to identify baseline predictors of change in readiness (from initial to final intervention session).
At the initial intervention session, 70.3% (N = 104) scored in pre-action (precontemplation/contemplation, preparation), and 29.7% (N = 44) in action/maintenance. Depressive symptomatology (χ2(2) = 9.08, p = 0.011) and low compensatory strategy use (F(2, 147) = 8.44, p = 0.001) at baseline were associated with lower readiness levels at initial ABLE session. By final ABLE session, most participants demonstrated greater readiness: 72% (N = 105) in action/maintenance, 28% (N = 41) in pre-action (two participants dropped out). A significant baseline predictor of positive change in readiness (from initial to final session) was higher social support levels (b = 0.10, SE = 0.05, Wald = 4.98, p = 0.026).
Whereas presence of depressive symptomatology and lower use of compensatory strategies at baseline were associated with lower readiness at initial intervention session, neither predicted change in readiness level. Thus, mood and prior compensatory strategy use do not effect enhancements in readiness to use strategies provided in an intervention. Baseline social support was the strongest predictor of change in readiness suggesting that interventions may need to involve older adults' social networks to enhance acceptability of compensatory strategy use.
补偿策略(行为/环境改变)可以减少日常生活活动、跌倒恐惧和死亡风险的困难。然而,个体在使用策略的准备程度上存在差异。我们研究了与使用补偿策略的准备程度相关的特征,以及从提供补偿策略的干预(促进老年人更好生活(ABLE))中参与程度对准备程度的改变程度,以及对准备程度变化的预测因素。
使用了一项随机试验的数据。参与者为 148 名老年人,被分配到 ABLE 干预组,该干预组旨在通过使用补偿策略来增强日常功能。基线测量包括人口统计学特征、功能困难程度、是否存在抑郁症状、补偿策略的使用情况和社会支持。在初始(从基线开始 2 周)和最终(6 个月)ABLE 会议上,干预者对参与者使用策略的准备程度(1 = 无意愿;2 = 考虑;3 = 准备;4 = 行动/维持)进行了评分。有序逻辑回归用于确定与初始准备评分相关的基线特征。采用 McNemar-Bowker 对称性检验描述准备程度的变化,采用二项逻辑回归确定基线对准备程度变化(从初始干预会议到最终干预会议)的预测因素。
在初始干预会议上,70.3%(N=104)的参与者得分处于行动前(无意愿/考虑,准备),29.7%(N=44)的参与者得分处于行动中/维持。基线时的抑郁症状(χ2(2)=9.08,p=0.011)和低补偿策略使用(F(2,147)=8.44,p=0.001)与初始 ABLE 会议时较低的准备程度相关。在最终的 ABLE 会议上,大多数参与者表现出更高的准备程度:72%(N=105)处于行动/维持,28%(N=41)处于行动前(两名参与者退出)。社会支持水平较高(b=0.10,SE=0.05,Wald=4.98,p=0.026)是准备程度积极变化的显著基线预测因素。
虽然基线时存在抑郁症状和较低的补偿策略使用与初始干预会议时的准备程度较低相关,但两者均不能预测准备程度的变化。因此,情绪和先前的补偿策略使用并不会影响干预中提供的使用策略的准备程度的提高。基线社会支持是准备程度变化的最强预测因素,这表明干预可能需要涉及老年人的社交网络,以提高对补偿策略使用的接受程度。
