Therapist beliefs about exposure therapy implementation

Perceptions and Use of Extended-Duration Exposure Therapy Amongst Psychologists

BACKGROUND

Extended-duration exposure therapy, in which treatment is delivered over a single prolonged session or cluster of long-duration sessions, is a highly efficacious and efficient treatment for anxiety disorders such as specific phobias. Despite this, little is known about the use of extended-duration exposure therapy in clinical practice.

METHODS

In the present study we investigated the perceptions and use of extended-duration exposure therapy amongst a sample of Australian psychologists via a survey, and the Therapist Beliefs about Exposure Scale. Additionally, we compared theoretical understanding of exposure therapy, and therapy delivery strategies (using a case study vignette), between psychologists who deliver exposure therapy via an extended-duration mode, versus the more traditional multi-session mode.

RESULTS

Extended-duration exposure therapy is widely underutilised, and this is associated with negative beliefs about exposure therapy in general, as well as several practical barriers. There were no differences in the reported theoretical mechanisms of exposure therapy between those who do and do not use extended-duration exposure therapy. However, psychologists who use extended-duration exposure therapy reported greater use of strategies with demonstrated efficacy (e.g., more intense delivery) and less use of therapy-interfering strategies (e.g., distress reduction techniques) relative to those who do not use extended-duration exposure therapy.

CONCLUSION

These findings identify potential mechanisms accounting for extended-duration exposure therapy's efficiency and point to strategies that may increase the uptake of extended-duration exposure therapy in clinical practice.

Determinants of Exposure Therapy Implementation in Clinical Practice for the Treatment of Anxiety, OCD, and PTSD: A Systematic Review

Exposure therapy (ET) forms a vital part of effective psychotherapy for anxiety-related presentations including anxiety disorders, obsessive-compulsive disorder (OCD), and post-traumatic stress disorder (PTSD), and is often underutilised in clinical practice. Using the Theoretical Domains Framework (TDF), this systematic review synthesised existing literature on the determinants of ET implementation for anxiety-related presentations and examined differences across presentations and developmental subgroups. Fifty-two eligible studies were assessed using the Mixed Methods Appraisal Tool, with 389 results (99%) mapped onto the TDF. Results suggested that clinicians' negative beliefs about the consequences of ET were commonly associated with reduced implementation. It also appeared that whilst broad unspecified ET training may be related to improved implementation for anxiety disorders; greater implementation for complex presentations (i.e., PTSD) likely requires more specialised training involving practical components. A subset of domains (e.g., social/professional role and identity) accounted for most results, whilst some remain unexplored (i.e., optimism; reinforcement; memory, attention, and decision processes) or underexplored (i.e., behavioural regulation). Likewise, specific presentations and developmental subgroups (i.e., PTSD and adults) represented a greater proportion of results in the literature than others (i.e., OCD and youth). Future research exploring ET implementation, across specific presentations and developmental subgroups, would benefit from integrating implementation science frameworks to guide the development of targeted, comprehensive strategies to close the research-practice gap of ET for the treatment of anxiety-related presentations.

Maladaptive therapist schemas in CBT practice, training and supervision: A scoping review

BACKGROUND

Maladaptive therapist schemas are hypothesized to generate difficulties within cognitive behavioural therapy (CBT) practice, training and supervision. Without adequate identification and management, they negatively affect the cognitions and emotions of the therapist, leading them to behave in ways that risk ruptures or therapy and supervision being delivered in a suboptimal fashion. Consequently, there is a need to synthesize the research that has been undertaken to date on the content, prevalence, identification and management of maladaptive therapist schemas.

METHOD

A scoping review was undertaken of studies that have been published since 2001 on the impact of maladaptive therapist schemas (also referred to interchangeably as beliefs or cognitions) in CBT practice, training and supervision. Thirteen studies were identified in a literature search from four electronic databases, a reference list search of identified articles and hand searches.

RESULTS

Three overall themes were identified in the research: (1) prevalence of therapist schemas, (2) specific therapist beliefs and (3) therapist characteristics associated with the delivery of suboptimal CBT or supervision. While there is little empirical support for therapist schemas, therapist resistance and beliefs relating to the fear of using exposure therapy were identified. Therapist intolerance of uncertainty and self-esteem were recurrent factors.

CONCLUSION

There is no consensus on how to define, identify, formulate or respond to maladaptive therapist beliefs or schemas in clinical practice, training or supervision. Further research is needed to better understand their origins, maintaining factors and appropriate management of their impact.
