Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Behavioral weight loss treatment (BWLT) is a proven way to lose weight and keep it off. BWLT usually includes individual or group sessions with a health professional to learn strategies and tools to change behaviours and thoughts in order to support weight loss. However, few studies have designed a BWLT with the unique needs of patients with PsA in mind.
Before testing new treatments for chronic disease in large, expensive studies, it is important to do smaller-scale research to make sure that a future large study will be successful. In line with this, the objective of our study is to test the feasibility of a future, large study of a BWLT for patients with PsA and obesity. In other words, our small feasibility study will investigate how convenient, reasonable, and acceptable the future study's procedures are, using a small group of people with PsA and obesity.
People who have PsA and obesity will take either a special BWLT program, or receive usual care for PsA from a community-based rheumatologist. Those in the BWLT group will complete 16 online group sessions to help them learn cognitive and behavioral changes to help improve their health and manage weight. After 24 weeks, we will determine study completion rates, examine patient satisfaction, and assess whether the BWLT was provided to people as-designed. We believe this research will help with efforts to provide more effective treatments to patients with PsA to help them lose weight and improve their quality of life through reduced pain and symptoms.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Aims: The primary aim of the proposed trial will evaluate feasibility metrics (i.e., recruitment rate, drop-out, intervention fidelity, acceptability) of a randomized controlled clinical trial testing an adaptation of a validated "small changes"-based BWLT approach. The secondary aim is to examine differences in mean weight loss, self-reported PsA symptoms (e.g., pain, mobility) and health related quality of life (HRQOL) between patients randomized to BWLT versus patients in the control condition who receive treatment as usual (at a community-based rheumatology clinic).
Methods: The proposed study is a single center, open label parallel-group randomized control feasibility trial. Our study will control for the effect of treatment as usual in a community-based rheumatology clinic (i.e., medication and behaviour self-management). Patients will undergo baseline assessments and then will be randomized (1:1) to either the "small changes" BWLT or treatment as usual (TAU). The Small Changes BWLT is a cognitive-behavioural treatment program that was developed as an alternative to traditional behavioral therapy based on high treatment failure rates and weight regain across time - particularly in high-risk populations. Patients are provided with education on weight loss-promoting behaviour changes and encouraged to set SMALL \[Self-selected, Measurable, Action-Oriented, Linked to your Life, and (Time) Limited\] goals aimed at increasing self-efficacy and satisfaction, while decreasing feelings of deprivation in order to achieve sustained, long term weight loss in participants. The BWLT group will receive 16, weekly, 2-hour group-based sessions led by an undergraduate-level coach (i.e., BKin). Content covered includes nutrition, physical activity, mindfulness, cognitive restructuring, managing stress, sleep, social support, and problem-solving and is consistent with recent Canadian obesity treatment guidelines. The TAU group will received usual care from the Balfour community rheumatology clinic in Penticton, B.C. Feasibility metrics (i.e., drop-out/retention rates, patient adherence, patient-reported satisfaction with the BWLT etc.) will be assessed at the primary endpoint of 24-weeks post-randomization. Secondary outcomes (weight loss, PsA symptoms, HRQOL) will be
Impact/Future Directions: The results from the proposed study will be used to inform and develop a subsequent, adequately powered, randomized controlled efficacy trial investigating the primary outcome of weight-loss among patients with PsA and obesity who receive a BWLT, relative to TAU controls. Ultimately, the implementation of the BWLT to a community-based rheumatology clinic has potential to improve the quality of life in patients with PsA and comorbid obesity.

RANDOMIZED
PARALLEL
Participants in the control group will continue to receive their treatment as usual from the Balfour Medical Clinic and be put on a waitlist for the BWLT. This group will receive the same treatment as the intervention group after the intervention group has received treatment.
