Brief Summary:
"Harvest for Health" is a home-based vegetable gardening intervention that pairs cancer survivors with certified master gardeners (MGs) from the Cooperative Extension System, the education and outreach arm of land-grant universities nationwide.

Condition or disease Intervention/treatment Phase
Cancer Survivor Behavioral: home-based, mentored vegetable gardening program Not Applicable

Detailed Description:
Few lifestyle behavior change interventions have been successfully translated into practice. Addressing this research-to-practice gap is a significant research and public health priority. "Harvest for Health" is a home-based vegetable gardening intervention that pairs cancer survivors with certified Master Gardeners from the Cooperative Extension System. The parent study was started at the University of Alabama at Birmingham and is currently being conducted throughout the entire state of Alabama. Preliminary findings suggest that this intervention increases vegetable consumption and physical activity, and improves physical functioning and health-related quality of life. We propose a feasibility study to adapt this promising program to the multi-cultural population of cancer survivors and for the local context (physical, social, and cultural environment) of New Mexico. We will then implement the adapted program, "Southwest Harvest for Health" and evaluate feasibility, acceptability, and fidelity. The adaptation phase is a critical first step towards widespread dissemination, implementation, and scale-up of an evidence-based intervention.

Arm Intervention/treatment
Experimental: Single Arm
All participants will receive the 10-month mentored, vegetable gardening intervention
Behavioral: home-based, mentored vegetable gardening program
The mentored vegetable gardening program pairs each participant with a certified Master Gardener. The participant/Master Gardener dyads work together to plan, plant and tend to a vegetable garden at the participant's home throughout the year. Gardening supplies, plants and seeds are provided.




Primary Outcome Measures :
  1. Adaptation -- systematic documentation using the Framework for Reporting Adaptations and Modifications Enhanced (FRAME) tool (Stirman et al., Implementation Science, 2019) [ Time Frame: through study completion, an average of 9 months ]
    Adaptation is "the degree to which an intervention is modified in the process of its adoption and implementation." Adaptation requires a careful balance between achieving fit, i.e., modifying a program to meet the needs of a new target population or local context, and maintaining fidelity, i.e., minimizing changes that could negatively affect the program's effectiveness. Adaptation of the Harvest for Health intervention for the local context (physical, social, and cultural environment) of New Mexico

  2. Feasibility of the intervention [ Time Frame: through study completion, an average of 9 months ]
    Ability to recruit 25 cancer survivors in 3 months, achieve 80% retention rates, 80% adherence to the intervention, and high acceptability of the program for both cancer survivors (participants) and Cooperative Extension Master Gardeners.


Secondary Outcome Measures :
  1. Pre-post change in vegetable and fruit intake [ Time Frame: baseline to 9-months ]
    The number of daily servings of vegetables and fruits will be measured by the Eating at America's Table Screener (EATS) questionnaire; this 10-item NCI-developed questionnaire will be able to assess whether individuals increase by more than one serving of vegetables/fruits per day.

  2. Pre-post change in objectively measured physical activity [ Time Frame: baseline to 9-months ]
    Physical activity will be objectively measured using the activPAL research grade monitor.

  3. Pre-post change in sleep quality [ Time Frame: baseline to 9-months ]
    Self-reported sleep quality will be assessed using the PROMIS 8-item questionnaires for sleep impairment and sleep disturbance.

  4. Pre-post change in physical function [ Time Frame: baseline to 9-months ]
    Self-reported physical function will be assessed using the 8-item physical function scale.

  5. Pre-post change in physical performance [ Time Frame: baseline to 9-months ]
    Physical performance will be objectively measured using the Rikli & Jones Senior Fitness Battery.
