Data_Sheet_1_Improving Acceptability and Uptake Behavior for Internet-Based Cognitive-Behavioral Therapy.pdf

Internet-based cognitive behavioral therapy (iCBT) programs have the potential to improve access to mental healthcare, but they are not viewed as acceptable nor widely utilized by the general public. This study tested whether two acceptance-facilitating interventions improved acceptability and uptake-related behavior for therapist assisted and self-guided iCBT. Participants were randomly assigned to read a treatment rationale for iCBT (vs. a brief definition) and to receive a small financial incentive (or not) for seeking more information about evidence-based iCBT programs. Participants (N = 662) were a diverse group recruited from a University participant pool and the surrounding community. Participants completed standardized measures of attitudes toward and outcome expectancy for iCBT and a single question about willingness to use it and were given the opportunity to get information about accessing evidence-based iCBT programs. A series of MANCOVAs showed small, positive effects of the treatment rationale on attitudes and outcome expectancy for both self-guided and therapist-assisted iCBT, but not for willingness to use it. A hierarchical logistic regression model found no effect of the treatment rationale or financial incentive on whether participants sought additional information about how to access iCBT, although psychopathology symptoms and identifying as White or multiracial were positively associated with information-seeking. Inconsistent with past research, participants rated therapist-assisted and self-guided iCBT as equally acceptable. Participants recruited from the community reported greater willingness to use iCBT than University students. These results underscore the urgent need for further research toward improving the acceptability and uptake of iCBT so that it may better fulfill its potential to fill the gap in unmet mental health need.

基于互联网的认知行为疗法（iCBT）项目有望提升心理健康服务的可及性，然而，它们并未被公众普遍接受，也未得到广泛应用。本研究旨在检验两种促进接受度的干预措施是否能够提升对治疗辅助和自我引导iCBT的接受度及其采纳相关行为。参与者被随机分配阅读iCBT的治疗依据（与简短定义相对比）以及是否获得寻求更多关于基于证据的iCBT项目信息的少量经济激励。参与者（N = 662）为一群多元化的群体，他们来自大学参与者池及其周边社区。参与者完成了对iCBT态度和结果预期的标准化测量，并对使用iCBT的意愿进行了单一问题的调查，并被赋予了获取关于如何获取基于证据的iCBT项目信息的可能。一系列的MANCOVA分析显示，治疗依据对自我引导和治疗辅助iCBT的态度和结果预期具有微小且积极的影响，但对使用意愿并无影响。与以往研究不一致的是，参与者将治疗辅助和自我引导iCBT视为同等可接受。来自社区的参与者报告称，他们比大学生更有意愿使用iCBT。这些结果强调了进一步研究以提升iCBT的接受度和采纳度的紧迫需求，以便它能更好地满足未满足的心理健康需求。
