Investigating the Impact of Mindfulness on Psychological Well-being of Stroke Survivors and Their Caregivers: A Randomized Controlled Trial.

Stroke prevalence is 3-4% among Singaporeans above the age of 50, and will rise with our aging population. Stroke survivors face many concerns, including physical, psychological, cognitive and psychosocial consequences of stroke, as well as impaired functioning and quality of life. They often rely on their family for physical, cognitive and emotional support in order to perform daily functional activities. Dependence on family members has been shown to affect the physical, mental and emotional well-being of caregivers of stroke survivors. Research indicates that the long-term demands of caring for a stroke survivor puts a strain on caregivers who may not be able to provide the appropriate amount of care required to manage the needs of stroke survivors over time.

Mindfulness-based interventions (MBIs) are increasingly being offered as psychotherapeutic interventions for individuals who suffer from medical conditions such as stroke, and for their long-term family caregivers. Several review studies have shown that MBIs, specifically for long-term conditions, enhanced the ability to cope with physical difficulties, improved mental and emotional well-being as well as overall quality of life, promoting better health outcomes. A systematic review investigating the use of MBIs with stroke survivors found that psychological, physiological and psychosocial outcomes were improved, such as anxiety, depression, mental fatigue and overall quality of life (Lawrence et al., 2013).

However, there are limited data for stroke survivors and their caregivers especially among Asians. Furthermore, there is little attention to study the interaction between participants characteristics and MBIs to determine whether there are any specific moderators that help to maximize the therapeutic outcomes of MBIs (Shaprio et al., 2011). Although there are growing number of studies correlating personality traits and dispositional mindfulness (Hanley, 2016; Giluk, 2009), little research has been done to examine personality traits as moderators to treatment outcome. Research focusing the the five-factor model of personality has demonstrated that the five personality traits have different strengths of correlation with the dispositional mindfulness. Among the traits, neuroticism displayed the strongest negative correlation with depositional mindfulness while conscientiousness displayed the strongest positive correlation with depositional mindfulness.

This study will be the first to examine the moderating effects of personality traits on the impact of mindfulness-based intervention in terms of depression, anxiety, stress and perceived quality of life of stroke survivors and their family caregivers. Furthermore, this study will evaluate and compare the impacts of mindfulness-based intervention and health education on the psychological well-being of both the participants. Findings will encourage the development of future strategies to understand the variability in treatment response and prognosis as well as to address individual differences with relevant psychotherapy skills.
