Personal Relevance, Trust and Privacy Concerns Among Cancer Survivors Who Did Not Visit a Research Website Offering Free Genetic Counseling Services for Families (Preprint)

Abstract

Digital health tools, such as online websites now proliferate to assist individuals in managing their health. With user input, we developed the Your Family Connects (YFC) website to promote access to genetic services for survivors of ovarian cancer and their relatives. While we estimated that half or more would access the website, only 18% of invited survivors did so. We assessed the extent to which perceived relevance of the information provided, trust and privacy concerns influenced decisions not to access the website.

We designed a theory-based cross-sectional survey to explore the following questions: (1) to what extent did nonresponders endorse privacy concerns; (2) were privacy concerns associated with recall of receiving the website invitation, time since diagnosis, age, and race; and (3) could we identify profiles of nonresponders that would guide the development of future interventions to encourage engagement in health websites for families affected by inherited cancers?

A sample of survivors who were eligible to access the website yet did not respond to the study invitation were identified by linking study IDs to the Georgia Cancer Registry (GCR) information. The survey was brief and contained 27 items including recall of the invitation, perceived salience of ovarian cancer risk assessment, benefits of using health websites, trust in health websites, and trust in university-based health research. We conducted confirmatory factor analyses (CFA), regression analyses, ANOVA, correlation analyses, and logistic regression to address research questions.

Of the 650 nonresponders who we sent the short survey, 368 (56.3%) responded and provided sufficient data for analysis. The mean response of 2.57 on the trust scale was significantly below the scale midpoint of 3, t(360)=11.78, p < .001, suggesting that survivors who did not log on were on average distrustful of health websites. Belonging to a minority group was associated with being most trusting and less skeptical about health websites. Just 196 nonresponders (30.1%) recalled the invitation to visit the website. Logistic regression analysis indicated that age was the only significant predictor of recall. Testing a model with age, minority status, and the six privacy concerns correctly classified 58.8% of nonresponders, a rate of successful classification that wThe nonresponders in the present study—particularly the White non-responders—were skeptical of website platforms regardless of whether they recalled receiving a website invitation or not.

The nonresponders in the present study—particularly the White non-responders—were skeptical of website platforms regardless of whether they recalled receiving a website invitation or not. Social marketing approaches geared toward building trust in web platforms by building a relationship with an information consumer and in collaboration with trusted organizations warrants further investigation.
