Behavioral Exposure for Interoceptive Tolerance (BE-FIT): A stage II randomized clinical trial protocol.

Background: Exercise anxiety is a novel mechanism related to non-adherence to exercise and lifestyle physical activity. We developed a cognitive-behavioral treatment, Behavioral Exposure For Interoceptive Tolerance (BE-FIT), which is a manualized, values-based exposure intervention designed to target exercise anxiety that is delivered as a supplement to outpatient cardiac rehabilitation (CR).

Method: We describe a Stage II randomized controlled trial (RCT) to test BE-FIT, compared to a Health Education Control (HEC) intervention on exercise and physical activity outcomes at end-of-treatment (EOT) and follow-ups (Weeks 12, 18, and 24), and evaluate mechanisms of change (i.

Physiological Effects of Psychological Interventions Among Persons with Financial Stress: A Systematic Review, Meta-analysis, and Introduction to Psychophysiological Economics.

It is known that economic problems can cause psychological stress, and that psychological stress causes physiological changes often linked to disease. Here we report a systematic review and meta-analysis of studies on physiological effects of psychological treatment for individuals with economic problems. Of 5071 papers in our initial PsycInfo search, we identified 16 papers on physiological effects for psychological treatment of the economically stressed.

Linking measures to mechanisms of action in behavior change: A qualitative analysis of expert views.

Rationale: Testing mechanisms of action (MoAs) hypothesized to underlie behavior change can enhance intervention effectiveness. Rigorous measurement of putative mechanisms is critical to this effort, but measures are rarely validated with respect to target MoAs.

Objective: This study aimed to elucidate challenges of linking measures to putative MoAs and to identify priorities for future research.

Health insurance, perceived threat, and posttraumatic stress after suspected acute coronary syndrome.

Objective: Threat perceptions during evaluation for acute coronary syndrome (ACS) in the emergency department (ED) predict posttraumatic stress symptoms (PSS). It is unknown how health insurance status affects threat perceptions. We tested whether lacking health insurance is associated with higher threat perceptions and PSS in patients with suspected ACS in the ED and whether threat perceptions mediate associations between lack of health insurance and subsequent PSS.

Linking measures to mechanisms of action: An expert opinion study.

Objective: This study sought to integrate the NIH Science of Behaviour Change (SOBC) measures repository comprising measures of putative mechanisms with mechanisms of action (MoA) identified by the Human Behaviour-Change Project (HBCP).

Design: Participants were 30 international experts recruited from professional networks and societies. In three anonymous virtual rounds, experts established consensus on hypothesized links between 26 MoAs and 44 self-report measures.
