Positive and negative affect change following psychotherapeutic treatment for anxiety-related disorders: A systematic review and meta-analysis.

BACKGROUND: Anxiety-related disorders feature elevated negative affect (NA), and in some cases, diminished positive affect (PA). It remains unclear how well extant psychotherapies for anxiety-related disorders improve PA versus NA. METHODS: We systematically searched the Cochrane Central Register of Controlled Trials, PubMed, PsychInfo, and Web of Science databases. Records included studies involving (1) patients with a principal or co-principal diagnosis of at least one anxiety-related disorder (i.e., generalized anxiety, social anxiety, panic, agoraphobia, health anxiety, specific phobia, obsessive-compulsive disorder, or posttraumatic stress disorder), and (2) pre- and post-treatment PA and NA scores or a change index between pre- and post-treatment PA and NA scores. Effect sizes were calculated for meta-analyses. RESULTS: Fourteen studies with 1001 adults with an anxiety-related disorder were included. Psychotherapeutic interventions included cognitive behavioral, present-centered, and imagery-based approaches. Treatments reduced NA (g = -0.90; 95%CI [-1.19, -0.61]) to a greater extent than they improved PA (g = 0.27; 95%CI [0.05, 0.59]), Z = -5.26, p < .001. The limited number of studies available precluded analyses of the relationship between changes in affect and symptoms. LIMITATIONS: Results should be considered with caution given the small number and heterogeneity of included studies. CONCLUSIONS: Current psychotherapeutic interventions for anxiety-related disorders may not improve PA and NA to comparable levels.

Behavioral and neural mechanisms of latent inhibition.

Fear is an adaptive emotion that serves to protect an organism against potential dangers. It is often studied using classical conditioning paradigms where a conditioned stimulus is paired with an aversive unconditioned stimulus to induce a threat response. Less commonly studied is a phenomenon that is related to this form of conditioning, known as latent inhibition. Latent inhibition (LI) is a paradigm in which a neutral cue is repeatedly presented in the absence of any aversive associations. Subsequent pairing of this pre-exposed cue with an aversive stimulus typically leads to reduced expression of a conditioned fear/threat response. In this article, we review some of the theoretical basis for LI and its behavioral and neural mechanisms. We compare and contrast LI and fear/threat extinction-a process in which a previously conditioned cue is repeatedly presented in the absence of aversive outcomes. We end with highlighting the potential clinical utility of LI. Particularly, we focus on how LI application could be useful for enhancing resilience, especially for individuals who are more prone to continuous exposure to trauma and stressful environments, such as healthcare workers and first responders. The knowledge to be gained from advancing our understanding of neural mechanisms in latent inhibition could be applicable across psychiatric disorders characterized by exaggerated fear responses and impaired emotion regulation.

A Preliminary Investigation of Provider Attitudes Toward a Transdiagnostic Treatment: Outcomes from Training Workshops with the Unified Protocol.

Evidence-based psychological treatments (EBPTs) for common mental health conditions are efficacious but remain underutilized in clinical service settings. Novel transdiagnostic and modular approaches that treat several disorders simultaneously promise to address common barriers to the dissemination and implementation of traditional EBPTs. Despite the promise that transdiagnostic treatments hold, the claims that these interventions can be more easily disseminated and implemented have not been widely tested. The present study examined whether a transdiagnostic treatment, the Unified Protocol (UP), addresses some barriers to dissemination and implementation for clinicians. Exploratory aims of the current study were to examine the effects of a UP introductory training workshop on clinician attitudes and behaviors by: (1) evaluating UP knowledge and treatment delivery, (2) determining relationships between clinician characteristics and their knowledge acquisition, satisfaction with UP, and UP penetration, and (3) exploring clinicians' perceptions of the UP's characteristics utilizing mixed methods. Workshop participants showed a good understanding of UP treatment concepts following training, and over a third of survey respondents reported use of the intervention 6-months after training. Positive attitudes toward EBPTs and fewer years of clinical practice were associated with greater satisfaction with the UP. Clinicians held positive views of the UP's flexibility and relative advantage over standard EBPTs but held negative views toward the manual's design and packaging. Overall, our findings suggest that clinicians may view transdiagnostic treatments such as the UP favorably and may consider them appealing over standard EBPTs. However, barriers associated with traditional EBPTs may extend to transdiagnostic treatments like the UP.
