      abstract     = {An important prerequisite for actively engaging in cancer
                      prevention and early detection measures, which is
                      particularly recommended in cases of familial cancer risk,
                      is the acquisition of information. Although a lot of cancer
                      information is available, not all social groups are equally
                      well reached because information needs and communicative
                      accessibility differ. Previous research has shown that a
                      live chat service provided by health professionals could be
                      an appropriate, low-threshold format to meet individual
                      information needs on sensitive health topics such as
                      familial cancer risk. An established German Cancer
                      Information Service is currently developing such a live chat
                      service. As it is only worthwhile if accepted by the target
                      groups, formative evaluation is essential in the course of
                      the chat service's development and implementation.This study
                      aimed to explore the acceptance of a live chat on familial
                      cancer risk by patients with cancer and their relatives
                      (research question [RQ] 1) and examine the explanatory power
                      of factors associated with their intentions to use such a
                      service (RQ2). Guided by the Extended Unified Theory of
                      Acceptance and Use of Technology (UTAUT2), we examined the
                      explanatory power of the following UTAUT2 factors:
                      performance expectancy, effort expectancy, social influence,
                      facilitating conditions, and habit, supplemented by
                      perceived information insufficiency, perceived
                      susceptibility, perceived severity, and cancer diagnosis as
                      additional factors related to information seeking about
                      familial cancer.We conducted a cross-sectional survey via a
                      German web-based access panel in March 2022 that was
                      stratified by age, gender, and education (N=1084). The
                      participants are or have been diagnosed with cancer
                      themselves (n=144) or have relatives who are or have been
                      affected (n=990). All constructs were measured with
                      established scales. To answer RQ1, descriptive data (mean
                      values and distribution) were used. For RQ2, a blockwise
                      multiple linear regression analysis was conducted.Overall,
                      $32.7\%$ of participants were (rather) willing, $28.9\%$
                      were undecided, and $38.4\%$ were (rather) not willing to
                      use a live chat on familial cancer risk in the future. A
                      multiple linear regression analysis explained $47\%$ of the
                      variance. It revealed that performance expectancy, social
                      influence, habit, perceived susceptibility, and perceived
                      severity were positively associated with the intention to
                      use a live chat on familial cancer risk. Effort expectancy,
                      facilitating conditions, information insufficiency, and
                      cancer diagnosis were not related to usage intentions.A live
                      chat seems promising for providing information on familial
                      cancer risk. When promoting the service, the personal
                      benefits should be addressed in particular. UTAUT2 is an
                      effective theoretical framework for explaining live chat
                      usage intentions and does not need to be extended in the
                      context of familial cancer risk.},
