Background: This study explored the transformative outcomes of programmes and activities for family caregivers of people with dementia in Taiwan. Methods: Transformative learning theory was used to examine the relationship between participation and positive outcomes. A group of nonparticipants was included to provide a complete picture of the transformative learning process. In this qualitative study, 18 participants were interviewed with audio recording, and the data were transcribed verbatim. A thematic analysis was performed to determine the themes and subthemes in the results. Findings: The results revealed that participation in programmes and activities was not the single factor leading to transformative outcomes; family support, self-adjustment, the ability to cope, and coordinated intervention in accordance with individual preferences and needs also facilitated transformative outcomes for nonparticipants. Conclusions: Further studies should focus on interventions modifying factors of perceived caregiver burden, for instance, by providing psychological support to informal caregivers, offering programmes and activities targeting the management of neuropsychiatric symptoms in patients with dementia, and supporting quality of life.
