Webâbased virtual reality to enhance behavioural skills training and weight loss in a commercial online weight management programme: The Experience Success randomized trial
Summary Objective Commercial online weight management programmes are popular and easily accessible but often lack training in empirically validated behaviour change strategies and produce suboptimal outcomes. This study evaluated the effects of a Webâbased virtual reality (VR) programme for enhancing behavioural skills training and weight loss when offered as an adjunct to a commercial online weight management programme. Methods N = 146 adults with overweight/obesity (body mass index [BMI] 27â40 kg/m2) were randomized to 6 months of noâcost access to the Weight Watchers (WW) online platform alone or enhanced with the Experience Success (WW + ES) programme, consisting of four Webâbased VR sessions for training in behavioural weightâloss skills related to the home environment, the workplace, physical activity and social situations (i.e., a party at a friend's house). Weight was measured at the research centre at baseline, 3 and 6 months. Results Both groups achieved statistically significant weight loss across the trial, with no difference in mean ± standard error (SE) weight loss between WW and WW + ES at 3 months (2.7 ± 1.1 kg vs. 4.2 ± 1.1 kg, respectively; P = .086) but greater weight loss in WW + ES at 6 months (2.6 ± 1.3 kg vs. 4.9 ± 1.3 kg, respectively; P = .042). Conclusions This study demonstrates the potential of Webâbased VR skills training to enhance outcomes of commercial online weight management programmes that are widely accessible. Compared with traditional didactic methods for online skills training, VR simulation provides opportunities to learn behavioural skills via modelling and experiment with skills in realâworld situations. More research is needed to identify specific behavioural mechanisms by which ES may improve outcomes

The influence of posttraumatic stress disorder treatment on anxiety sensitivity: Impact of prolonged exposure, sertraline, and their combination
Trauma-informed beliefs often decrease during posttraumatic stress disorder (PTSD) treatment. This may also extend to anxiety sensitivity (AS), defined as a fear of anxiety-related sensations and beliefs that anxiety is dangerous and/or intolerable. However, little is known about how AS changes during exposure-based and psychopharmacological PTSD treatments. Further, high AS may be a risk factor for diminished PTSD symptom improvement and increased treatment dropout. To better understand how AS impacts and is impacted by PTSD treatment, we conducted a secondary analysis of a randomized clinical trial with a sample of 223 veterans (87.0% male, 57.5% White) with PTSD from four U.S. sites. Veterans were randomized to receive prolonged exposure (PE) plus placebo (n = 74), sertraline plus enhanced medication management (n = 74), or PE plus sertraline (n = 75). Veterans answered questions about PTSD symptoms and AS at baseline and 6-, 12-, 24-, 36-, and 52-week follow-ups. High baseline AS was related to high levels of PTSD severity at 24 weeks across all conditions, ÎČ = .244, p = .013, but did not predict dropout from exposure-based, ÎČ = .077, p = .374, or psychopharmacological therapy, ÎČ = .009, p = .893. AS also significantly decreased across all three treatment arms, with no between-group differences; these reductions were maintained at the 52-week follow-up. These findings suggest that high AS is a risk factor for attenuated PTSD treatment response but also provide evidence that AS can be improved by both PE and an enhanced psychopharmacological intervention for PTSD
Increased Smoking Cessation Among Veterans With Large Decreases in Posttraumatic Stress Disorder Severity.
IntroductionImprovement in posttraumatic stress disorder (PTSD) is associated with better health behavior such as better medication adherence and greater use of nutrition and weight loss programs. However, it is not known if reducing PTSD severity is associated with smoking cessation, a poor health behavior common in patients with PTSD.Aims and methodsVeterans Health Affairs (VHA) medical record data (2008-2015) were used to identify patients with PTSD diagnosed in specialty care. Clinically meaningful PTSD improvement was defined as â„20 point PTSD Checklist (PCL) decrease from the first PCL â„50 and the last available PCL within 12 months and at least 8 weeks later. The association between clinically meaningful PTSD improvement and smoking cessation within 2 years after baseline among 449 smokers was estimated in Cox proportional hazard models. Entropy balancing controlled for confounding.ResultsOn average, patients were 39.4 (SD = 12.9) years of age, 86.6% were male and 71.5% were white. We observed clinically meaningful PTSD improvement in 19.8% of participants. Overall, 19.4% quit smoking in year 1 and 16.6% in year 2. More patients with versus without clinically meaningful PTSD improvement stopped smoking (n = 36, cumulative incidence = 40.5% vs. 111, cumulative incidence = 30.8%, respectively). After controlling for confounding, patients with versus without clinically meaningful PTSD improvement were more likely to stop smoking within 2 years (hazard ratio = 1.57; 95% confidence interval: 1.04-2.36).ConclusionsPatients with clinically meaningful PTSD improvement were significantly more likely to stop smoking. Further research should determine if targeted interventions are needed or whether improvement in PTSD symptoms is sufficient to enable smoking cessation.ImplicationsPatients with PTSD are more likely to develop chronic health conditions such as heart disease and diabetes. Poor health behaviors, including smoking, partly explain the risk for chronic disease in this patient population. Our results demonstrate that clinically meaningful PTSD improvement is followed by greater likelihood of smoking cessation. Thus, PTSD treatment may enable healthier behaviors and reduce risk for smoking-related disease
PTSD improvement and substance use disorder treatment utilization in veterans: Evidence from medical record data
BackgroundClinical trials reveal posttraumatic stress disorder (PTSD) improvement leads to decreased substance use among patients with comorbid substance use disorder (SUD). Using administrative medical record data, we determined whether clinically meaningful PTSD Checklist (PCL) (â„20 points) score decreases were positively associated with SUD treatment utilization.MethodsWe used a retrospective cohort of Veterans Health Affairs (VHA) medical record data (2008-2015). PTSD Checklist (PCL) scores were used to categorize patients into those with a clinically meaningful PTSD improvement (â„20 point decrease) or not (<20 point decrease or increase). PTSD and SUD were measured by ICD-9 codes. Propensity score weighting controlled for confounding in logistic and negative binomial models that estimated the association between clinically meaningful PTSD improvement and use of SUD treatment and number of SUD clinic visits.ResultsThe 699 eligible patients were, on average, 40.4 (±13.2) years old, 66.2% white and 33.1% were married. After controlling for confounding, there was a 56% increased odds of any SUD treatment utilization among those with a PCL decrease â„20 vs < 20 (OR = 1.56; 95%CI = 1.04-2.33) but there was no association with number of SUD treatment visits.ConclusionsClinically meaningful reductions in PTSD symptoms were associated with any SUD treatment utilization but not amount of utilization. Improvement in PTSD symptoms, independent of the treatment modality, may enable SUD treatment seeking

Change in posttraumatic stress disorderârelated thoughts during treatment: Do thoughts drive change when pills are involved?
Posttraumatic negative thoughts about oneâs self and the world are related to posttraumatic stress disorder (PTSD) symptom severity and change in cognitive behavioral treatment (CBT), but little is known about this association when CBT is delivered with medication. The current study presents a planned comparison of changes in negative posttraumatic thoughts during (a) prolonged exposure (PE) plus pill placebo (PE+PLB), (b) sertraline plus enhanced medication management (SERT+EMM), and (c) PE plus sertraline (PE+SERT) as part of a randomized clinical trial in a sample of 176 veterans. Lagged regression modeling revealed that change in posttraumatic negative thoughts was associated with PTSD symptom change in the conditions in which participants received sertraline, ds = 0.14â0.25, ps = 0.04â.001). However, contrary to previous research, the models that started with symptom change were also statistically significant, d = 0.23, p < .001, for the lagged effect of symptoms on negative thoughts about self in the SERT+EMM condition, indicating a bidirectional association between such thoughts and PTSD symptoms. In the PE+PLB condition, no significant association between posttraumatic thoughts and PTSD symptoms emerged in either direction. These results suggest that the previously demonstrated role of change in posttraumatic thoughts leading to PTSD symptom reduction in PE may be altered when combined with pill administration, either active or placebo.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/172308/1/jts22762_am.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/172308/2/jts22762.pd
