Objective
To provide effect size estimates of the impact of two cognitive rehabilitation interventions provided to patients with Mild Cognitive Impairment (MCI): computerized brain fitness exercise (BF) and memory support system (MSS), on support partners' outcomes of depression, anxiety, quality of life, and partner burden.
Methods
Randomized controlled pilot trial.
Results
At 6 months, the partners from both treatment groups showed stable to improved depression scores, while partners in an untreated control group showed worsening depression over six months. There were no statistically significant differences on anxiety, quality of life or burden outcomes in this small pilot trial; however, effect sizes were moderate suggesting the sample sizes in this pilot study were not adequate to detect statistical significance.
Conclusion
Either form of cognitive rehabilitation may help partners' mood, compared to providing no treatment. However, effect size estimates related to other partner outcomes (i.e., burden, quality of life, anxiety) suggest follow-up efficacy trials will need sample sizes of at least 30-100 people per group to accurately determine significance.
