Experiences of trauma and stressful conflicts are common, with most adults in the United States reporting experiences of at least one traumatic event in their lifetimes. Experiences of stressful events vary, and may include war-related trauma, physical, emotional, and sexual abuse, witnessing violence or substance use in the household, and emotional and physical neglect. Exposure to traumatic and stressful events has been linked to adverse physical and psychological health outcomes, impaired functioning, and substantial reductions in quality of life. In addition to trauma exposure, many individuals experience interpersonal and intrapersonal conflicts such as experiences of social rejection, struggles with intimacy or autonomy in relationships, shameful secrets, and perfectionism. Such conflicts are also associated with poor psychological and physical health outcomes. Experiences of trauma and stressful conflicts often underlie many psychological problems that lead individuals to seek psychotherapy.

Many psychotherapy approaches aim to help people disclose and process difficult experiences and activate and experience their emotions, and research suggests that such psychotherapies improve psychological and physical health. For example, written emotional disclosure (or expressive writing) is a therapeutic approach in which a person is asked to write repeatedly about private stressful experiences and avoided emotions. Another psychotherapy approach, Prolonged Exposure Therapy (PE), is designed to help clients approach feared and avoided trauma-related material including memories, thoughts, emotions, and real-life situations. Short-Term Psychodynamic Psychotherapy (STPP) is an approach that helps clients acknowledge and engage with avoided emotions and psychological conflicts and express blocked emotions. One variant of STPP has been used to specifically treat affect phobia, a phobia of experiencing or expressing certain emotions. Emotional Awareness and Expression Therapy (EAET) borrows from STPP, exposure therapy, expressive writing, and other emotion-focused approaches and aims to help people disclose stressful experiences and emotional conflicts and experience and express their emotions related to stressful situations.

The aforementioned psychotherapy approaches have shown benefits for a range of populations and psychological and physical health outcomes; however, this therapeutic work can be challenging, and therapists may often avoid implementing such approaches and skills. Eliciting client disclosure and emotional activation can be especially challenging for novel therapists who may avoid directly inquiring about clients' traumas and conflicts and may experience difficulty tuning into and working with clients' emotions. These barriers are often observed in the implementation of exposure-based approaches, which are underutilized in day-to-day clinical practice. Barriers to therapist implementation of exposure-based techniques include lack of adequate training, the belief that exposure is likely to lead to an increase in symptoms or problems in therapy, and lack confidence in one's ability to handle a range of client emotional reactions.

Comprehensive training experiences are needed to address therapist-centric barriers to utilization of disclosure elicitation and emotional activation skills and to increase therapist self-efficacy related to such skills. Research suggests that entirely didactic training methods, such as reading manuals or watching lectures and training videos, are insufficient to lead to therapist behavior change. Several studies have highlighted the importance of supervision and supervisor feedback in increasing therapist knowledge, proficiency, and retention of therapeutic skills. Additionally, some researchers have highlighted the importance of key components of skill acquisition, such as repetitive or deliberate practice of specific skills through role plays and simulations, personalized performance feedback, and experiential/reflective training approaches. Therapist self-reflection and self-regulation practices have also been highlighted as an important component of skill training, as such practices can help therapists tune into and regulate their own in-session reactions and emotions. Several studies have also aimed to address, through training, therapists' anxiety, affect phobia (fear of intense emotional experiences), and the desire to avoid emotionally challenging therapeutic moments. These studies have highlighted the importance of increasing trainees' emotional awareness, helping trainees manage their reactions to client disclosure and emotional expression, and targeting and challenging clinician anxieties and concerns during psychotherapy skill training.

Overall, research suggests that efforts to improve therapist utilization of disclosure elicitation and emotional activation skills must not only provide "how to" training, but also directly address therapists' reservations, fears, and concerns related to disclosure and emotions. This suggests that providing therapists with a training experience that is experiential, includes practice, direct supervision and feedback, and addresses therapists' reservations and anxieties may be an important approach to increase therapist skills in disclosure elicitation and emotional activation. The current study aims to test the effects of an experiential, supervised training approach on therapy trainees' disclosure elicitation and emotional activation skills, and trainees' self-efficacy and affect phobia (fear of emotions), compared to a standard, didactic training approach. It is hypothesized that the experiential training condition will result in greater improvement in performance of the targeted skills and in higher participant ratings of satisfaction with the training compared to the standard training condition. It is also hypothesized that the experiential training condition will result in a greater increase in trainees' self-efficacy and greater decrease in trainees' affect phobia compared to the standard training condition.
