title: Comparing the efficiency of eight-session versus four-session memory intervention for older adults.
abstract: 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.
