Evidence that reduced treatment achieves similar outcomes is beneficial because shorter interventions may be more cost-effective and more acceptable to participants. We examined the effects of shortening a memory intervention for elders from eight sessions to four sessions. Shortening the intervention had little impact on either self-reported or performance measures of memory and daily living activities. Small to moderate effects were associated with positive changes in both groups. When examining cost-effectiveness, an eight-session intervention produced slightly greater gains in memory performance, but at a higher cost. Future studies should systematically vary key intervention components in more diverse samples.
有证据表明减少治疗次数能取得相似的效果，这是有益的，因为更短的干预可能更具成本效益，且更容易被参与者接受。我们研究了将针对老年人的记忆干预从八次缩短至四次的效果。缩短干预对自我报告的记忆和日常生活活动指标或表现指标几乎没有影响。两组均出现了小到中等程度的积极变化。在考察成本效益时，八次干预在记忆表现方面产生的提升略大，但成本更高。未来的研究应在更多样化的样本中系统地改变关键干预组成部分。
