Effectiveness of cognitive training in Chinese older people with subjective cognitive complaints: a randomized placebo-controlled trial

Topic: Risk, prevention and care in population studies
Objective This study examines the short-term and long-term effects of a cognitive training (CT) program in enhancing cognitive function of older people with subjective memory complaints. Methods A single-blind randomized placebo-controlled trial was carried out in a sample of 223 older adults aged 65 years or above with subjective memory complaints in Hong Kong. They were randomly assigned to either receive CT (intervention group, N = 111) or attend health-related educational lectures only (control group, N = 112). Participants' cognitive abilities were assessed by the Chinese version of Mattis Dementia Rating Scale at baseline, immediately after the training, and nine months after the training. Results Significant interaction effect of CT and education was detected on participants' CT gains at both T2 (F(2, 200) = 6.329, p = 0.002, η(2) = 0.060) and T3 (F(2, 189) = 3.294, p = 0.039, η(2) = 0.034). Conclusions Cognitive training was effective in enhancing the overall cognitive functioning of less educated older adults with subjective memory complaints. The positive effect was durable for at least nine months in two cognitive areas, namely conceptualization and memory.

How this study scored 74/100
Published in a peer-reviewed journal, and it is a randomised controlled trial. Scored zero for effect reported because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 43 of the 58 points we could judge it on, which is 74 out of 100.
