The BASIL + trial (Behavioral Activation in Social Isolation) is a National Institute of Health Research (NIHR) funded and approved trial sponsored by Tees, Esk and Wear Valleys NHS Foundation Trust (TEWV) and led by the University of York in the United Kingdom (UK).~Behavioral Activation (BA) is a type of support that may be beneficial for individuals who suffer from social isolation and/ or depression symptoms. BA assists in the continuation or introduction of activities that are significant to patients. These exercises may be beneficial to both physical and emotional health.~The BASIL+ study aims to find out if BA helps reduce or prevent depression and loneliness in older adults who have ongoing health conditions during isolation in the pandemic due to COVID-19.~Chronic pain affects approximately 50-60% of UK older adults and often coexists with depression. This comorbid indication affects approximately 13% of older adults. The literature on the impact of pain on depression outcomes has been steadily rising. Patients who suffer from depression with comorbid pain report significantly lower benefits, including less relief from depressive symptoms and limits the effectiveness of collaborative care for older adults with depression in the US. The collaborative care focused on antidepressant therapy and problem-solving therapy. Together, these findings suggest that pain may be a potential barrier to depression treatment response. It is unknown, however, how chronic pain impacts depression and the treatment of BA.~This sub-study nested in the BASIL+ trial provides an opportunity to explore how chronic pain impacts depression and the treatment they received
This qualitative nested sub-study will aim to explore how chronic pain (as defined as pain lasting for more than 3 months) impacts older adults' depression and treatment in a brief psychological therapy of behavioral activation (BA)
