Use of the nominal group technique to identify stakeholder priorities and inform survey development: an example with informal caregivers of people with scleroderma

Objectives

The nominal group technique (NGT) allows stakeholders to directly generate items for needs assessment surveys. The objective was to demonstrate the use of NGT discussions to develop survey items on (1) challenges experienced by informal caregivers of people living with systemic sclerosis (SSc) and (2) preferences for support services.

Design

Three NGT groups were conducted. In each group, participants generated lists of challenges and preferred formats for support services. Participants shared items, and a master list was compiled, then reviewed by participants to remove or merge overlapping items. Once a final list of items was generated, participants independently rated challenges on a scale from 1 (not at all important) to 10 (extremely important) and support services on a scale from 1 (not at all likely to use) to 10 (very likely to use). Lists generated in the NGT discussions were subsequently reviewed and integrated into a single list by research team members.

Setting

SSc patient conferences held in the USA and Canada.

Participants

Informal caregivers who previously or currently were providing care for a family member or friend with SSc.

Results

A total of six men and seven women participated in the NGT discussions. Mean age was 59.8 years (SD=12.6). Participants provided care for a partner (n=8), parent (n=1), child (n=2) or friend (n=2). A list of 61 unique challenges was generated with challenges related to gaps in information, resources and support needs identified most frequently. A list of 18 unique support services was generated; most involved online or in-person delivery of emotional support and educational material about SSc.

Conclusions

The NGT was an efficient method for obtaining survey items directly from SSc caregivers on important challenges and preferences for support services.
