An intervention that works
Like most of Bricker’s behavior-changing apps, iCanQuit is based on Acceptance and Commitment Therapy, or ACT, which encourages users to acknowledge and accept cravings in order to move past them.
A 2020 study involving more than 2,400 adult smokers throughout the U.S. compared Bricker’s iCanQuit with QuitGuide and found the Fred Hutch-tested app was almost 1.5 times more effective than QuitGuide in helping smokers stop smoking after 12 months.
“We think the approaches of ACT to accept cravings and follow your core values would resonate with American Indian and Alaska Natives,” he said.
A preliminary study comparing the efficacy of the two apps among American Indians and Native Alaskans from 31 states did indeed find that iCanQuit was “more efficacious, engaging, and satisfactory among American Indians and Alaska Natives nationwide.”
Now, the team will recruit around 800 study participants, starting in about a year, to run a larger trial with multiple aims.
One will be to biochemically verify abstinence from smoking in order to show which app works better. Another will determine whether one of the two apps is better at mediating cues to smoke and triggering personal motivations to quit, such as family, community and honoring the earth.
Finally, Bricker and his collaborators plan to analyze the data to further determine if the apps’ efficacy depends on gender, income level or whether the person is a heavy or light smoker. They also plan to conduct qualitative interviews with a small subset of participants to better understand their experience.
“The results of our last aim will inform our approach to disseminating iCanQuit throughout American Indian and Alaska Native tribal communities and organizations,” he said. “Eventually, we believe our smoking cessation program has potential for broad dissemination and high impact.”
As with many public health researchers, it’s all about finding new ways to upend longstanding health inequities.
"This research project is important for addressing serious cancer disparities among American Indians/Alaska Natives,” Bricker said. “Among all U.S. racial/ethnic populations, Indigenous people have the highest rates of combustible cigarette smoking and few resources to help them quit.
“We truly believe we can improve health equity by providing a highly accessible and efficacious intervention,” he said, adding the work also dovetails with the White House's Cancer Moonshot focus on addressing disparities in access to effective smoking cessation programs.
