RATIONALE: Considering the perspectives of individuals with cognitive disability is important for their participation in their self-directed health care. The nominal group technique (NGT) has been identified as a method to gather opinions of people with cognitive disability; however, a synthesis of methodological considerations to undertake when employing the approach among people with cognitive disability is non-existent.
METHOD: A systematic review guided by the preferred reporting items for systematic review and meta-analysis protocols was undertaken. Five databases (CINAHL, ISI Web of Science, ProQuest Social Science Journals, Scopus, and MEDLINE) were searched for peer-reviewed literature published before September 2016. Methodological considerations pertaining to the four stages of the NGT- generating ideas, recording ideas, clarification, and ranking - were extracted from each study.
RESULTS: Nine publications contributing to eight studies were included. Methodological considerations focused on (i) the number of participants within discussion groups, (ii) research question introduction, (iii) support individuals and accessible methods, (iv) ranking, and (v) researcher training and counselling services.
CONCLUSIONS: The use of the NGT to gain the health care perspectives of adults with cognitive disability is promising. Conducting nominal group techniques informed by the methodological considerations identified within this review can work towards ensuring that the health care perspectives of people with cognitive disability are considered. Implications for rehabilitation The emergent policy move towards self-directed health care for people with disability requires that the health care perspectives of people with disability are considered. Effective consultation and discussion techniques are essential to gain the health care perspectives of people with cognitive disability. After undertaking methodological considerations, the NGT can be an effective approach towards gaining the health care perspectives of people with cognitive disability.
