Developing a theoretically informed education programme within the context of a complex implementation strategy in UK primary care: an exemplar from the IMP2ART trial.

BACKGROUND: IMPlementing IMProved Asthma self-management as RouTine (IMP2ART) is a programme of work developing and evaluating a strategy for implementing supported asthma self-management in UK primary care. The strategy encompasses patient-facing resources, professional education, and organisational approaches to embed supported self-management. This paper reports the development of a theoretically informed interprofessional education programme which aims to raise awareness of and enable healthcare professionals to deliver effective supported self-management. METHODS: Aligned with the Medical Research Council (MRC) Complex Intervention Framework, the multidisciplinary team developed educational content in three phases: (1) developmental phase, identifying educational and behaviour change theory to guide development, in consultation with a professional advisory group; (2) feasibility pilot phase, testing the education using a 'think-aloud' method; and (3) pre-pilot phase, delivering the education within the IMP2ART strategy. RESULTS: The developmental phase identified educational and behaviour change theory and the need to provide two education modules: (1) a team module to raise awareness of supported asthma self-management for the whole team and (2) an individual study module for those who conduct asthma reviews with patients. The feasibility pilot highlighted content and design features in need of refinement and the pre-pilot identified substantial changes to the delivery strategy for the education modules. CONCLUSIONS: A multi-stage development process, aligned with the MRC Framework, contributed to the module design and delivery. Prior explorative work, multi-disciplinary team discussions, and professional advisory group consultation, informed the initial development, and in-practice testing and pre-pilot stages enabled refinement. In our experience, there were important benefits of working together as an educationalist/researcher team. The education programme, a core component of the implementation strategy, is now being tested in the IMP2ART UK-wide cluster randomised controlled trial.

Negative Affect-Related Autonomic Arousal Mediates the Association between Baroreflex Dysfunction and Insulin Resistance in Non-Diabetic Young Adults.

Autonomic dysfunction, in particular under-regulation of heart rate (HR) by the baroreflex, is implicated in development of insulin resistance (IR). According to reactivity hypothesis, sympathetic response to stressors may be more sensitive at predicting IR than baroreceptor sensitivity (BRS), a baseline measure of baroreflex functioning. Using ecological momentary assessment (EMA) of negative affect coupled with minute-to-minute HR and heart-rate variability (HRV) monitoring, we examined whether negative affect (NA)-related autonomic arousal mediates the association of BRS with IR. At baseline, BRS was measured, and fasting serum glucose and insulin levels were collected from 178 young adults (18-39 years old), from which homeostasis model assessment of IR (HOMA-IR) and beta-cell functioning (HOMA %B) were derived. Participants subsequently underwent one day of Holter HR and HRV monitoring while reporting negative affect levels via EMA. Multilevel modeling was used to assess the associations of momentary negative affect with HR and low- (LF) and high-frequency (HF) HRV during the 5-minute intervals following each EMA reading. Structural equation modeling was then used to determine whether individual differences in these associations mediated the association of BRS with IR, measured by HOMA-IR, HOMA %B, and insulin levels. As predicted, BRS was negatively associated with the IR (ß = -.17, p = .024). However, NA-related autonomic arousal mediated their association, accounting for 56% of the covariance between BRS and IR. Not only do these results provide support for reactivity hypothesis, they reveal a potential point of intervention in the treatment of affective dysregulation.

Lifetime Smoking Patterns and Preferences for Smoking Cessation Among Women Veterans Receiving Veterans Health Administration Care.

The objective of this study was to identify common themes among women veterans who smoke or recently quit and had used smoking cessation treatment within the Veterans Health Administration (VHA). The study built upon previous research by utilizing in-depth interviews to encourage disclosure of potentially stigmatized topics. Twenty women veterans enrolled in VHA care engaged in a quality improvement project focused on improving smoking cessation services. Qualitative analysis of de-identified interviews used a combination of content analysis and thematic analysis within the sociopharmacological model of tobacco addiction. Findings revealed that participants' smoking was influenced by woman veteran identity and by several gender-related contextual factors, including military sexual trauma and gender discrimination. Findings also highlighted other contextual factors, such as personal autonomy, emotional smoking triggers, and chronic mental health concerns. Findings are interpreted within the context of cultural power imbalances, and recommendations are provided for VHA smoking cessation for women veterans.

Roles of Guilt Cognitions in Trauma-Related Sleep Disturbance in Military Veterans With Posttraumatic Stress Disorder.

Objective/Background: Despite a well-established role of guilt cognitions in the maintenance and treatment of posttraumatic stress disorder (PTSD), relationships of guilt cognitions to nightmares are not well understood. This study investigated the ways in which guilt cognitions, related to traumatic events, influenced the relationship between combat exposure and trauma-related sleep disturbance in military Veterans with PTSD. Participants: We recruited a sample of 50 Veterans with PTSD who completed study measures at a screening session. Methods: Participants completed self-report measures of exposure to potentially traumatic events, trauma-related guilt (hindsight bias, wrongdoing, and lack of justification) and trauma-related sleep disturbance as measured by a self-report scale and clinician ratings of nightmare severity. Results: Bivariate regression analyses established a relationship of combat exposure to wrongdoing (ß = .31, p = .031), and a relationship of wrongdoing with self-reported trauma-related sleep disturbance (ß = .27, p = .049) and clinician-rated nightmare severity (ß = .36, p = .009). Bootstrapping analysis that included years of education as a covariate found a significant overall indirect effect of combat exposure on clinician-rated nightmare severity exerted through wrongdoing (ß = .10, 95% CI [.004, .246]). Conclusions: Results suggest the association of combat exposure with trauma-related sleep disturbance is significantly influenced by perceived wrongdoing related to a traumatic event. Targeting cognitions related to wrongdoing and moral injury during a traumatic event in PTSD treatment may help ameliorate trauma-related sleep disturbance.

Examination of the indirect effects of combat exposure on suicidal behavior in veterans.

BACKGROUND: Researchers have theorized that increased rates of suicide in the military are associated with combat exposure; however, this hypothesis has received inconsistent support in the literature, potentially because combat exposure may be indirectly related to suicide risk through its influence on posttraumatic stress disorder (PTSD) and depressive symptoms. The current study tested the hypothesis that combat exposure has a significant indirect effect on suicidal behavior among Iraq/Afghanistan-era veterans through its effects on PTSD-depressive symptomatology. METHODS: Iraq/Afghanistan-era veterans (N = 3,238) participated in a cross-sectional, multi-site study of post-deployment mental health consisting of clinical interviews and self-report questionnaires. Structural equation modeling (SEM) was used to examine direct and indirect relationships between three latent variables: combat exposure, PTSD-depression, and suicidal behavior (past attempts and current ideation, intent, and preparation). RESULTS: A partial mediation model was the best-fitting model for the data. Combat exposure was significantly associated with PTSD-depression (ß = 0.50, p < .001), which was in turn associated with suicidal behavior (ß = 0.62, p < .001). As expected, the indirect effect between combat exposure and suicidal behavior was statistically significant, ß = 0.31, p < .001. LIMITATIONS: Data were cross-sectional, and suicidal behavior was measured via self-report. CONCLUSIONS: Results indicated that combat exposure was indirectly related to suicidal behavior via PTSD-depressive symptomatology. Findings lend support for a higher-order combined PTSD-depression latent factor and suggest that Iraq/Afghanistan-era veterans with high levels of PTSD-depressive symptoms are at increased risk for suicidal behavior.

Low Income as a Multiplicative Risk Factor for Oral Pain and Dental Problems Among U.S. Veteran Smokers.

PURPOSE: Compared to the United States (U.S.) general population, military veterans are at an increased risk of experiencing dental problems. This study documented associations between cigarette use and measures of dental/oral concern in a population of U.S. veterans who served in Iraq and Afghanistan. METHOD: A cross-sectional analysis of survey data from the Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Veterans Health and Needs Study, a study of U.S. military veterans. Out of 5000 surveys mailed to a random sample of OEF/OIF veterans, 1161 surveys were completed and returned. Among study respondents, N = 1114 had non-missing dental/oral pain data and were included for analysis. The survey also included smoking history and demographic information. Univariate and multivariate logistic regression analyses were used to cross-sectionally model the odds of experiencing dental/oral concerns as a function of smoking status. We also examined moderating effects of income and gender on the association between smoking and dental/oral concerns. RESULTS: In univariate and multivariate models, current smoking was associated with risk for dental/oral concerns. However, this association was qualified by a Smoking × Income interaction. For those earning above US$20,000, smoking was not associated with dental/oral concerns. Among veterans with low income, smoking was associated with three times higher odds of increased dental/oral concerns. There was no significant Gender × Smoking interaction. CONCLUSION: These findings underscore the relevance of factors that moderate the association between smoking and dental/oral concern, namely income. Findings also underscore the importance of interventions to mitigate income disparities in oral healthcare.
