Efficacy and implementation of exercise-based smoking cessation treatment for adults with high anxiety sensitivity (STEP): Study protocol for a randomized controlled trial.

Anxiety sensitivity (AS), reflecting the fear of bodily sensations, is a transdiagnostic vulnerability factor that underpins both affective psychopathology and smoking. Phase II research supports the efficacy of a 15-week community-based intervention (STEP) that combines high-intensity exercise offered by the YMCA with standard smoking cessation treatment (tobacco quitline and nicotine replacement therapy) for sedentary smokers with elevated AS. This Phase III study aims to enroll 360 adults to evaluate whether STEP efficacy for achieving smoking abstinence generalizes to Black and Hispanic smokers with elevated AS.

Effects of remotely-delivered physical activity education on exercise beliefs and intentions of active and nonactive cancer survivors and their partners.

Physical activity (PA) is recommended for cancer survivors and their romantic partners yet cancer couples may be unaware of the benefits of PA specific to them. Exercise interventions targeting survivors and partners simultaneously may prove effective at increasing exercise knowledge, intentions, and outcomes. To examine the effects of a remotely-delivered cancer-specific exercise education video on cancer survivors' and their partners' exercise knowledge, beliefs, and intentions. Cancer survivors (N = 209) and their romantic partners (N = 155) completed an online survey with an embedded education video randomized to half the sample. Group differences (education vs. control) on study constructs among the whole sample and on a subset of the sample not meeting exercise guidelines [i.e., less than 150 min of moderate to vigorous physical activity (MVPA) per week; 50.5% survivors, 45.1% partners] were examined. Group differences on study constructs were also tested between survivors and partners meeting exercise guidelines or not. Survivors and partners in the education condition were more likely to correctly report the MVPA guidelines. The education increased survivors' personal exercise importance, outcome expectations, and likelihood of joining an individual exercise program. Participants meeting guidelines were significantly different on multiple exercise beliefs compared to those who were not. Among those not meeting guidelines, the education increased survivors' belief in the importance of exercising with their partner. A remotely-delivered exercise education video increased exercise knowledge and beliefs, which represents an important step in the development of couples' exercise interventions for cancer survivors and their romantic partners.

Exercise, defined as intentional physical activity, is recommended for cancer survivors and their romantic partners. However, few know the specific benefits of exercise following a cancer diagnosis. Theories of health behavior change suggest that access to information may influence individuals' valued importance of and intentions for a health practice. This work tested if an online video about cancer-specific exercise benefits could modify cancer survivors' and their romantic partners' exercise knowledge and beliefs. Cancer survivors and their romantic partners individually completed an online survey. The educational video was randomly embedded into the survey for half of participants. Survivors and partners who received the educational video were more likely to correctly report established exercise guidelines compared to those who did not get the video. The educational video also increased survivors' personal exercise importance, outcome expectations for exercise, and likelihood of joining an individual exercise program. Among survivors who were less active than the recommended guidelines, the educational video increased their importance of exercising with their partner. This research shows that an online video about exercise after cancer increased both survivors' and their partners' exercise knowledge as well as survivors' exercise beliefs and intentions to take part in an exercise program.

Community-based smoking cessation treatment for adults with high anxiety sensitivity: a randomized clinical trial.

BACKGROUND AND AIMS: People with anxiety disorders are more likely to smoke and less likely to succeed when they try to quit. Anxiety sensitivity may underlie both phenomena, such that people with high anxiety sensitivity react to interoceptive distress by avoidance. This study aimed to test the efficacy of an exercise program that induced interoceptive distress and thereby created tolerance to this distress in a safe environment. DESIGN, SETTING AND PARTICIPANTS: Randomized clinical trial at four YMCA branches in Austin, Texas, USA. Participants [n = 150; 130 (86.7%) white; 101 (67.3%) female; meanage  = 38.6, standard deviation (SD)age  = 10.4] were adult, daily smokers with high anxiety sensitivity motivated to quit smoking, who reported no regular moderate-intensity exercise. INTERVENTIONS: Participants were assigned a YMCA personal trainer who guided them through a 15-week intervention aerobic exercise program. Participants assigned to the personalized intervention trained at 60-85% of their heart rate reserve (HRR), whereas participants assigned to the control intervention trained at 20-40% of their HRR. Participants in both groups received standard behavioral support and nicotine replacement therapy. MEASUREMENTS: The primary outcome was biologically verified 7-day point prevalence abstinence (PPA) at 6-month follow-up. FINDINGS: Sixty-one per cent of participants were available at the 6-month follow-up. PPA at 6 months was higher in the personalized intervention than the control intervention [27.6 versus 14.8%; odds ratio (OR) = 2.20, 95% confidence interval (CI) = 1.28, 3.80, P = 0.005], assuming missing at random. Anxiety sensitivity declined in both groups with no evidence that this differed between groups. CONCLUSIONS: An exercise program of high intensity increased abstinence from smoking in people with high anxiety sensitivity, but may not have done so by reducing anxiety sensitivity.

Approach bias retraining to augment smoking cessation: Study protocol for a randomized controlled trial.

Heavy users and addicted individuals have shown to develop an approach action tendency - or approach bias - toward stimuli related to the substance of interest. Emerging evidence points to approach bias retraining (ABR) as an effective aid for the treatment of addictive behaviors. The current study seeks to extend this work by testing, in a pilot study, whether standard smoking cessation treatment involving cognitive-behavioral therapy (CBT) and nicotine replacement therapy can be augmented by ABR. To this end, we will randomly assign 100 adult smokers to either ABR-augmented treatment or placebo-augmented treatment and compare the two conditions on short-term and long-term abstinence rates. The hope is that the findings of this study can inform treatment development for adult smokers.

The effects of exercise on transdiagnostic treatment targets: A meta-analytic review.

BACKGROUND: The present study meta-analytically reviewed the effects of exercise on four transdiagnostic treatment targets: anxiety sensitivity (AS), distress tolerance (DT), stress reactivity (SR), and general self-efficacy (GSE). METHODS: We conducted systematic searches of peer-reviewed studies in bibliographical databases (Cochrane Library, psychINFO, PubMed) before April 1, 2018. Only randomized controlled trials (RCT) evaluating the effect of exercise on AS, DT, SR, or GSE using at least one validated outcome instrument in a sample of adolescents (≥13 years old) or adults were selected. We employed a meta-analysis of effects using random-effects pooling modeling for each treatment target. RESULTS: The systematic search yielded 28 RCTs meeting eligibility criteria. Exercise interventions had a large effect on reducing AS (six studies, Hedges's g = 0.72, p = .001), a medium effect on increasing GSE (eight studies, Hedges's g = 0.59, p < .001), and a small effect on reducing SR (ten studies, Hedges's g = 0.32, p < .001). Evidence from four studies suggested that exercise interventions had a small but non-significant effect on increasing DT (Hedges's g = 0.21, p = .26). CONCLUSIONS: This meta-analysis provides preliminary evidence exercise can engage certain transdiagnostic targets. Further research is required to optimize exercise intervention parameters to achieve the strongest effects on these important mechanistic variables.

YMCA exercise intervention to augment smoking cessation treatment in adults with high anxiety sensitivity: Study protocol for a randomized controlled trial.

Extant evidence suggests that exercise can reduce anxiety related vulnerability factors, such as anxiety sensitivity (AS), or fear of bodily sensations related to anxiety, that negatively impact smoking cessation outcomes. Building upon emerging evidence supporting the efficacy of exercise as an aid for smoking cessation in adults with high AS, we are conducting a trial to examine the efficacy and feasibility of this clinical application when implemented in a community setting. Partnering with the YMCA, this study aims to enroll 150 adults in a standard smoking cessation protocol (i.e. counseling and nicotine replacement therapy) and randomly assign them to either 15 weeks of programmed vigorous-intensity or low-intensity exercise. Smoking abstinence data will be collected up to 6 months following the quit attempt.
