A participatory approach to understand what might be most meaningful to people living with dementia in a positive psychology intervention.

Objectives: This study aimed to understand which character strengths are most important for people living with dementia and therefore which strengths-based psychological interventions could be most meaningful and acceptable.

Methods: A participatory design, utilising Delphi methodology, was incorporated into an iterative three stage framework: (1) literature reviewed for Positive Psychology (PP) interventions and patient public involvement to define the character strengths; (2) modified Delphi ( = 10) identified which character strengths are most important for living with dementia; (3) focus groups ( = 14) explored which PP interventions are most acceptable and meaningful. Qualitative data from the focus groups was analysed using thematic analysis.

Results: Love, kindness and humour were deemed the most important character strengths for living with dementia. Qualitative data from the focus groups was captured in three superordinate themes: (1) lack of opportunity not capacity; (2) key considerations of PP interventions for people living with dementia; and (3) potential benefits of PP interventions.

Conclusions: Love, kindness and humour come naturally to people with dementia, but people may lack social opportunities to use these strengths. Therefore, a PP intervention promoting positive emotion, social relationships and connection to one's values appears most meaningful and acceptable as this may provide a social context to use and maintain these strengths.
