Navigating digital behavior change: a mixed-method examining the expert perspectives for cancer survivors

With the dramatic increase in the number of people with cancer, it is necessary to optimize new interventions that promote a healthy lifestyle. This study aimed to explore medical experts' experiences and perspectives regarding the acceptability and feasibility of digital behavior change interventions for Iranian cancer survivors, as well as to identify their potential benefits and barriers.

We employed a mixed-methods design to capture both the breadth and depth of clinical experts' perspectives on a digital lifestyle application for cancer survivors and to facilitate triangulation. In the quantitative phase, a standardized questionnaire was administered to 30 professionals, comprising both medical and psychology experts with extensive experience working with cancer survivors. To complement these findings, semi-structured interviews were conducted with a subset of 23 experts.

Quantitative analysis revealed that only a small proportion of participants had access to their patients outside of clinical visits. Nevertheless, participants broadly agreed on the feasibility of implementing digital behavior change interventions to support healthy lifestyle changes. Concerns were minimal, provided that such interventions deliver evidence-based information, integrate patient feedback, and maintain strict confidentiality. Complementary thematic analysis further highlighted digital interventions as promising tools for improving lifestyle behaviors among cancer survivors. Essential features for an effective intervention included user-friendliness, simple language, motivational and supportive design, trustworthiness, and cultural adaptability.

Our findings indicate that digital behavior change interventions are generally acceptable to Iranian medical experts, provided that potential enablers are leveraged and barriers are addressed to maximize their use. Implications for cancer survivors This study highlights the potential of digital behavior change applications to support cancer survivors in adopting and maintaining healthier lifestyles, particularly in underrepresented settings such as Iran. It also provides insight into key features to improve its acceptance, beside addressing potential barriers.
