The Development of an Integrated Physical Activity and Mental Health Intervention for Veterans With COPD, Emotion Distress, and Low Physical Activity

The current study will develop and test Step-Cognitive Behavioral Therapy (CBT) (Step-CBT), an integrated intervention that draws from existing pedometer-based physical activity (PA) interventions and brief CBT to target low PA, emotional distress, and physical disability in Veterans with chronic obstructive pulmonary disease (COPD) delivered via VA Video Connection (VVC). This study has three components: In Aim 1, we will conduct a cross-sectional study with 50 Veterans with COPD, low PA, and clinically significant depression and/or anxiety symptoms. Self-report measures will be collected and provide information on mean level and magnitude of the relations between PA, emotional distress, and physical disability. Participants will wear an ActiGraphy device for 14 days following their in-person session to measure objective PA. Based on these data, we will create Step-CBT, an intervention that integrates, tailors, and adapts a pedometer-based PA intervention and brief CBT (existing transdiagnostic protocol), based on patient interviews and current literature. In Aim 2, we will examine the acceptability of Step-CBT, an 8-session intervention delivered via VVC, in Veterans (N=6) collecting recruitment, enrollment, completion data and measures of physical functioning and emotional distress. We will conduct expert panel review of the manualized intervention protocol and acceptability results. In Aim 3, we will assess the feasibility of Step-CBT in a proof-of -concept study design in Veterans (N=40 enrolled with target of 25 completers) with COPD, low physical activity, and clinically significant depression and/or anxiety symptoms. The current research has great potential to improve physical and psychological functioning in Veterans with COPD through the development of an integrated PA-mental health intervention. Step-CBT delivered to patient's homes, would offer a safe option to increase/maintain physical functioning and mental health in Veterans with COPD.

Inclusion criteria

• Any gender-identified, greater than or equal to 40 years of age
• Clinical diagnosis of COPD defined as the presence of emphysema on a CT scan and one piece of clinical evidence of COPD (defined as a ratio of FEV1 to forced vital capacity < 0.70, > 10 pack-year cigarette smoking history, overall assessment of COPD in their problem list or in Pulmonary/Primary Care notes, or on bronchodilators (specifically antimuscarinics such as Tiotropium or Ipratropium). If there is no evidence of emphysema, or no CT on scan in their medical chart, three pieces of clinical evidence of COPD will suffice for a clinical diagnosis of COPD.
