Chronic conditions, such as obesity and diabetes, are increasing worldwide. Lifestyle changes (e.g., physical activity, healthy diet, sufficient sleep, managing stress, smoking cessation) are often recommended to prevent or manage these conditions, but changing habits is difficult. Mental health can play a role in the ability to seek out and follow through on the changes necessary to achieve or maintain a healthy lifestyle, yet this aspect is rarely addressed, and access to mental health services is often limited. Furthermore, individuals are influenced by factors at the individual, interpersonal, community and policy levels (e.g., lack of socialization, unsafe neighborhoods). These factors can act as barriers and need to be addressed in order for individuals to make sustainable lifestyle changes.
A new year-long person-centered healthy lifestyles program is proposed to address the "how to" gap in making lifestyle changes through a combination of individual and group sessions. The feasibility and implementation of this new program will be evaluated through a pilot study looking at the full healthy lifestyles program compared to a less intensive version of the program. The study's hypothesis is that the full program will be feasible, acceptable and more effective for helping participants move across stages of change and for meeting their goals than the less intensive program.
A pragmatic mixed methods design including a randomized controlled trial and qualitative components will be used for this pilot study. The randomized controlled trial will include a 1:1 allocation comparing a more intensive program (MIP - usual care plus healthy lifestyles program) with a less intensive program (LIP - usual care plus development of health goals).
The qualitative components include semi-structured interviews of participants (exit interviews at 12 months), MIP staff and participants' healthcare providers (at 6 months and 12 months). In addition, focus groups will be conducted with family members of MIP participants at 9 months. These elements will provide perspectives from multiple stakeholders for improving the healthy lifestyles program and on their roles in creating and maintaining healthy lifestyles.
The primary aim of this study is to assess the feasibility and implementation of the healthy lifestyles program. Impact on participant experiences and outcomes will also be measured. Findings from this study will help inform a larger randomized trial to further look at effectiveness of the program and to determine health system implications. A 2-year extension was approved in order to determine sustainability of findings.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| More Intensive Program (MIP) | Experimental | Participants will receive the more intensive program, which combines usual care with the full version of the healthy lifestyles program. Participants in this arm will meet weekly for group health and wellness learning sessions or brainstorming group sessions. In addition, they will meet monthly for individual sessions with a multidisciplinary health team, including a family physician, physical therapist and dietician to tailor their health goal development and action plans to their particular needs and situations. They will be asked to maintain physical activity and nutrition journals for a week each every three months. |
|
| Less Intensive Program (LIP) | Experimental | Participants will receive the less intensive program, which combines usual care along with health goal development. Participants in this arm will meet at baseline to set health goals with the support of a research assistant trained in theories of health behaviour and goal setting. They will also meet every three months to measure progress in achieving their goals. They will be asked to maintain physical activity and nutrition journals for a week each every three months. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Health and wellness learning sessions | Behavioral | The health and wellness learning sessions provide a platform for concepts from a variety of health behaviour theories and CBT to be combined with evidence- and practice-based recommendations for healthy lifestyles. They provide the basis for participants' development of an individualized action plan. The sessions will last one hour and participants will receive them in a group setting, 18 times throughout the duration of the program. Specifically, the sessions will be delivered during weeks: 1-8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48. |

| Changes in health goals - Stage of change over time | For each health goal, stage of change will be determined with a 7-point Likert scale. Comparisons will be made with baseline but also with other time points. | Baseline, 3 months, 6 months, 9 months and 12 months, 18 months, 24 months, 30 months, 36 months |

Enrolled participants will be allocated to one of the two intervention groups for the duration of the study. One group will be assigned to the more intensive program (MIP= usual care plus healthy lifestyles program) and the other group will be assigned to the less intensive program (LIP= usual care plus health goal development).

| Brainstorming group sessions | Behavioral | The brainstorming group sessions allow for facilitated discussions where individuals explore barriers and facilitators to achieving their goals and provide an interpersonal component to the program through the building of social interactions. Participants will also receive help in finding community programs to support healthy lifestyles. These sessions will last one hour and participants will receive them in a group setting, 30 times throughout the duration of the program. Specifically, these sessions will be delivered during weeks: 9-11, 13-15, 17-19, 21-23, 25-27, 29-31, 33-35, 37-39, 41-43, 45-47. |
|
| Individual sessions with a multidisciplinary health team | Behavioral | Monthly individual sessions with a family physician trained in medical CBT, a dietician and a physical therapist help individuals tailor their action plans and recommendations to their particular circumstances and provide supports based on their needs. The initial session will last 3 hours and occur at baseline. The follow-up sessions will last 1 hour. |
|
| Health goal development | Behavioral | Participants in both arms will develop health goals. Several components of these goals will be measured throughout the study, including the stage of change, self-efficacy and actual goal achievement. In the more intensive program arm, participants will develop health goals and learn about how to meet those goals through the group and individual sessions. In the less intensive program arm, participants will receive support in developing health goals from a research assistant trained in theories of health behaviour and in goal setting at baseline, 3 months, 6 months, 9 months and 12 months. The initial goal setting session will be provided within a time period of 2 hours, and the follow-up sessions will be provided within one hour time periods. |
|
| Physical activity and nutrition journals | Behavioral | Participants in both arm will be asked to maintain a physical activity journal and a nutrition journal for a week each every three months. These journals help participants reflect on current behaviours and areas for change. |
