초록
Mild cognitive impairment (MCI) is the sign of dementia, and is critical for prediction and preventing its progressions. This study aimed to review literature on cognitive communication intervention of MCI patients systematically, and propose the evidence-based data, including their effect sizes using a meta-analysis method. Thirty-eight researches published since 2012, meeting the inclusion and exclusion criteria, were entered into this analysis. They were analyzed in qualitative aspects, and their effect sizes were calculated in a level of mean and each domain. Outcome measures included the domains of 10 cognitions and 4 communications. The main findings were as follows. Firstly, the general target population for studies was MCI over the age of 50, and intervention programs were designed diversely in a session or mode. Secondly, several domains, including attention, memory, and executive function held a large portion of the intervention programs. Thirdly, the average effect size of interventions was large. Lastly, processing speed and word fluency were very effective and significant among domains in the results of treatment. Current study provides evidence-based information to support cognitive-communication intervention for individuals with MCI. These results also can contribute to diversify intervention approaches and verify their efficacies. Given this, it is possible to facilitate the cognitive-communication intervention for MCI in clinical settings.
Abstract
Mild cognitive impairment (MCI) is the sign of dementia, and is critical for prediction and preventing its progressions. This study aimed to review literature on cognitive communication intervention of MCI patients systematically, and propose the evidence-based data, including their effect sizes using a meta-analysis method. Thirty-eight researches published since 2012, meeting the inclusion and exclusion criteria, were entered into this analysis. They were analyzed in qualitative aspects, and their effect sizes were calculated in a level of mean and each domain. Outcome measures included the domains of 10 cognitions and 4 communications. The main findings were as follows. Firstly, the general target population for studies was MCI over the age of 50, and intervention programs were designed diversely in a session or mode. Secondly, several domains, including attention, memory, and executive function held a large portion of the intervention programs. Thirdly, the average effect size of interventions was large. Lastly, processing speed and word fluency were very effective and significant among domains in the results of treatment. Current study provides evidence-based information to support cognitive-communication intervention for individuals with MCI. These results also can contribute to diversify intervention approaches and verify their efficacies.
