Green Activity Program for Memory Challenges

This study is testing a program called the Green Activity Program, which involves nature activities like gardening or hiking. The program was created with people living with memory challenges and their study partners. The goal is to see if the program can be successfully implemented and if participants enjoy it, with the aim of helping people stay active and improve their health. You may be able to join if you are 45 or older, have memory challenges, and can use a phone. You would also need a study partner who is 18 or older and comfortable joining you. The study is currently unclear on its recruitment status and plans to enroll 40 pairs of participants.

Study design
This is a single-arm study, meaning all participants receive the Green Activity Program. It plans to enroll 40 pairs of participants (people living with memory challenges and their study partners).
What's involved
You would participate in a 12-week Green Activity Program. After the program, you and your study partner would have a brief 5-minute phone interview.
Compensation
Not stated in the trial record.
Follow-up
Your behavior change will be measured 4 weeks after the 12-week program ends. Acceptability of the program will be measured up to one month after the program.

What this trial measures

  • Feasibility intervention completion rateThrough study completion

    intervention completion rate of 75%

  • Other Feasibility measuresThrough study completion

    75% attendance, 75% retention, intervention fidelity using a checklist by an outside rater with at least 75% of potential active ingredients present in 25% of randomly sampled sessions: tailoring (environment, activity, personalized delivery), behavioral activation, and nature (outdoor environment or incorporating nature \[plant or animal\]). Feasibility data of recruitment rates (eligible participants/# recruited per month), feasibility of assessments (time to complete, with an 80% completion rate) will be collected, and we will also track missing data.

  • AcceptabilityUp to one month after the 12-week program.

    Two selected questions from the Intervention Tolerability scale will be asked to the person living with memory challenges over the phone: "The program was easy to use" and "I liked this program." Rated by (yes/no). We expect at least 70% of people living with memory challenges will be satisfied with the intervention (yes to both questions).
