Depression and anxiety disorders are among the most prevalent psychological difficulties and contribute to negative economic, social, and health outcomes. As they are frequently comorbid and share underlying mechanisms of dysfunction, many scholars have conceptualized these as a unified category of emotional disorders. Addressing processes contributing to dysfunction among individuals who are at risk for developing emotional disorders has the potential to prevent significant negative impact.~Acceptance and Commitment Therapy (ACT) has received empirical support in the treatment of depression and anxiety in a number of examinations. ACT aims to shape acceptance of challenging thoughts and feelings and engagement with areas of life one finds meaningful and important. The converse of acceptance, experiential avoidance, or the unwillingness to experience unpleasant thoughts and emotions even when doing so is maladaptive, has been predictive of symptoms of depression and anxiety. Reducing experiential avoidance and shaping alternative responses, such as acceptance and behavior consistent with one's values, termed committed action, is a promising strategy for targeting risk for emotional disorders.~Traditional means of delivering interventions fail to reach a substantial proportion of those who struggle with psychological difficulties. Barriers such as distance, time, and cost contribute to these challenges. Digital mental health interventions offer a means to overcome treatment barriers and increase access. These approaches can be delivered in individual's homes at the time of their choosing. Additionally, digital interventions can be delivered to many people at the same time, reducing cost. Support for the impact of ACT-informed digital interventions on symptoms of depression and anxiety has been obtained, suggesting that this framework is promising for reducing risk.~The goal of the current study is to compare the impact of a digital ACT-informed intervention on psychological symptoms and processes of change among individuals at risk for depression and anxiety. The following hypotheses will be evaluated:~Individuals in the treatment condition will experience a decrease in symptoms of depression and anxiety compared to those in the control group~Individuals in the treatment condition will experience a decrease in experiential avoidance and increase in values consistent behavior compared to those in the control group~The digital intervention will generally be rated positively~The relationship between cognitive fusion and treatment response will be explored
Depression and anxiety are frequently comorbid and share mechanisms contributing to dysfunction. Transdiagnostic approaches, such as Acceptance and Commitment Therapy, streamline intervention and allow a broader population to benefit in a cost-effective fashion. Brief ACT interventions targeting at-risk individuals have the potential to prevent negative outcomes. Delivering these in a digital format overcomes attitudinal and structural barriers to accessing treatment.
