SynopsisSummary of Gillen, G., Nilsen, D. M., Attridge, J., Banakos, E., Morgan, M., Winterbottom, L. & York, W. (2015). Effectiveness of interventions to improve occupational performance of people with cognitive impairments after stroke: An evidence-based review. American Journal of Occupational Therapy, 69(1), 6901180040, 1-9 (with further details on the methods provided in Arbesman, Lieberman & Berlanstein, 2015).Objective: To determine which interventions are effective in improving occupational performance for people with cognitive impairment after stroke. Design: Evidence-based literature review. Search strategies: Searches were conducted in multiple databases (Medline, PscyINFO, CINAHL, AgeLine, OTseeker); some journals were hand searched and review reference lists examined. Search terms for the population and intervention are provided, but the full search strategy is not. Selection criteria: Years: 2003-2012; Language: only English; Interventions: within the scope of occupational therapy practice; Study types: Level I (systematic reviews or randomised trials), II (cohort or case-control studies), and III (studies without a control group: pre-post test, beforeafter, or cross-sectional studies); Outcomes: must have measured real or simulated occupational performance; Population: people with stroke and cognitive impairment (it is not specified how cognitive impairment was determined or how mixed population samples were dealt with). Methods of review: Articles were reviewed according to their 'scientific rigour, and lack of bias, and level of evidence' (Arbesman et al., 2015, p. 5) and summarised using 'evidence tables', but limited details are provided about the critical appraisal process or the risk of bias of each study. Presentation of results of included studies is limited to sentences and p-values, with no effect sizes provided. Results: Forty-six articles met the inclusion criteria; 27 were Level I, nine were Level II, and 10 were Level III evidence. Results are presented in categories according to type of
