This study investigated the association between subtypes of social support availability (SSA) and memory in persons aged 45 to 85 years (n = 24,719). We examined two memory outcomes using a modified Rey Auditory Verbal Learning Test (RAVLT)-immediate recall (RAVLT I) and delayed recall (RAVLT II)-and five subtypes of SSA: affectionate, emotional/informational, positive interactions, tangible, overall. We found statistically significant and adjusted positive associations between all SSA subtypes and memory, except for positive interactions and delayed recall memory. For RAVLT I, the regression coefficients (βˆs) ranged from 0.03 to 0.07; the βˆs for RAVLT II ranged from 0.02 to 0.05. The differences in βˆs for each SSA subtype (βˆ RAVLT I - βˆ RAVLT II) ranged from 0.00 to 0.02 (mean difference = 0.01; 95% confidence interval = -0.01 to 0.03). All effect sizes, regardless of SSA subtype or memory outcome, were small and clinically unimportant.

社会支持可用性的亚型与记忆没有差异：对加拿大老龄化纵向研究综合队列的横断面分析。

本研究调查了 45 至 85 岁人群 (n = 24,719) 的社会支持可用性 (SSA) 亚型与记忆力之间的关联。我们使用改良的 Rey 听觉语言学习测试 (RAVLT) 检查了两种记忆结果——即刻回忆 (RAVLT I) 和延迟回忆 (RAVLT II)——以及 SSA 的五种亚型：深情、情感/信息、积极互动、有形、整体。我们发现所有 SSA 亚型和记忆之间具有统计学显着性和调整后的正相关性，除了正相互作用和延迟回忆记忆。对于 RAVLT I，回归系数 (β^s) 在 0.03 到 0.07 之间；RAVLT II 的 β^s 范围从 0.02 到 0.05。每个 SSA 亚型 (β^RAVLT I - β^RAVLT II) 的 β^s 差异范围为 0.00 至 0.02（平均差异 = 0.01；95% 置信区间 = -0.01 至 0.03）。
