Change in posttraumatic stress disorder-related thoughts during treatment: Do thoughts drive change when pills are involved?

Posttraumatic negative thoughts about one's 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 = 0.14-0.25, ps = 0.04-.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.

What Do Veterans Want? Understanding Veterans' Preferences for PTSD Treatment Delivery.

INTRODUCTION: Home-based delivery of psychotherapy may offer a viable alternative to traditional office-based treatment for post-traumatic stress disorder (PTSD) by overcoming several barriers to care. Little is known about patient perceptions of home-based mental health treatment modalities. This study assessed veterans' preferences for treatment delivery modalities and how demographic variables and trauma type impact these preferences. MATERIALS AND METHODS: Veterans with PTSD (N = 180) participating in a randomized clinical trial completed a clinician-administered PTSD assessment and were asked to identify their modality preference for receiving prolonged exposure: home-based telehealth (HBT), office-based telehealth (OBT), or in-home-in-person (IHIP). Ultimately, modality assignment was randomized, and veterans were not guaranteed their preferred modality. Descriptive statistics were used to examine first choice preference. Chi-square tests determined whether there were significant differences among first choice preferences; additional tests examined if age, sex, and military sexual trauma (MST) history were associated with preferences. RESULTS: The study includes 135 male veterans and 45 female veterans from all military branches; respondents were 46.30 years old, on average. Veterans were Caucasian (46%), African-American (28%), Asian-American (9%), American Indian or Alaskan Native (3%), Native Hawaiian or Pacific Islander (3%), and 11% identified as another race. Veterans experienced numerous trauma types (e.g., combat, sexual assault), and 29% had experienced MST. Overall, there was no clear preference for one modality: 42% of veterans preferred HBT, 32% preferred IHIP, and 26% preferred OBT. One-sample binomial tests assuming equal proportions were conducted to compare each pair of treatment options. HBT was significantly preferred over OBT (p = 0.01); there were no significant differences between the other pairs. A multinomial regression found that age group significantly predicted veterans' preferences for HBT compared to OBT (odds ratio [OR] = 10.02, 95% confidence interval [CI]: 1.63, 61.76). Older veterans were significantly more likely to request HBT compared to OBT. Veteran characteristics did not differentiate those who preferred IHIP to OBT. Because there were fewer women (n = 45), additional multinomial regressions were conducted on each sex separately. There was no age group effect among the male veterans. However, compared to female Veterans in the younger age group, older female Veterans were significantly more likely to request HBT over OBT (OR = 10.66, 95% CI: 1.68, 67.58, p = 0.012). MST history did not predict treatment preferences in any analysis. CONCLUSIONS: Fewer than 50% of the sample preferred one method, and each modality was preferred by at least a quarter of all participants, suggesting that one treatment modality does not fit all. Both home-based care options were desirable, highlighting the value of offering a range of options. The use of home-based care can expand access to care, particularly for rural veterans. The current study includes a diverse group of veterans and increases our understanding of how they would like to receive PTSD treatment. The study used a forced choice preference measure and did not examine the strength of preference, which limits conclusions. Future studies should examine the impact of modality preferences on treatment outcomes and engagement.
