Objectives: To identify influential factors for quality of life (QoL) among individuals with motor neurone disease (MND) and explore how regulatory flexibility and psychological flexibility may contribute towards maintaining and improving QoL. Methods: Semi-structured interviews were conducted with 26 individuals with MND. Thematic analysis, using both inductive and deductive analyses, was employed to examine subjective QoL in view of previous understanding of QoL. Results: Four factors were important for the QoL of participants: perceived illness prognosis, sense of self, concerns for significant others, and life to enjoy. These factors reflected psychological stress caused by MND, the participant's value system, and their beliefs about life. In optimising QoL, both regulatory flexibility and psychological flexibility were essential to maintain and enhance QoL. Often, regulatory flexibility was perceived among those employing a mindful approach, and psychological flexibility was found to involve savouring positive experiences. Conclusions: People with MND reported that seeking ways to both maintain and enhance their QoL is crucial, and that this may be accomplished by increasing flexibility through mindfulness and savouring. (171/200 words) ä IMPLICATIONS FOR REHABILITATION People with motor neurone disease (MND) seek to maintain quality of life (QoL) following changes caused by the condition, whilst attempting to enhance QoL by maximising their positive experiences. Regulatory flexibility is essential to maintain QoL and it was closely associated with mindful approach so that MND is not perceived as an inevitable threat to QoL. Psychological flexibility was found to enhance QoL and it involves savouring positive experiences, while abandoning fault-finding of the current situation. Positive inter-personal interactions can encourage people with MND to engage with mindfulness and savouring for favourable outcomes in terms of QoL; current support services should orient towards both mindfulness and savouring.
