Please click on the hyperlink in Additional Links field.Although long recognized in the clinical literature, problematic behavior characteristic of anxious drivers has received little empirical attention. The current research details development of a measure of anxious driving behavior conducted across three studies. Factor analytic techniques identified three dimensions of maladaptive behaviors across three college samples: anxiety-based performance deficits, exaggerated safety/caution behavior, and anxiety-related hostile/aggressive behavior. Performance deficits evidenced convergent associations with perceived driving skill and were broadly related to driving fear. Safety/caution behaviors demonstrated convergence with overt travel avoidance, although this relationship was inconsistent across studies. Safety/caution scores were associated specifically with accident- and social-related driving fears. Hostile/aggressive behaviors evidenced convergent relationships with driving anger and were associated specifically with accident-related fear. Internal consistencies were adequate, although some test-retest reliabilities were marginal in the unselected college sample. These data provide preliminary evidence for utility of the measure for both research and clinical practice

Post-traumatic stress disorder symptoms, pain, and perceived life control: Associations with psychosocial and physical functioning

The symptoms of PTSD and pain frequently co-occur following a traumatic event; however, very little is known about how these two conditions are associated with physical and psychosocial functioning. The current study intended to first examine the differential association of co-occurring pain complaints and PTSD symptoms with disability in the domains of psychosocial and physical functioning, and second, to test whether perceived life control is a mediator of these relationships. All participants experienced a motor vehicle accident (MVA) and reported pain due to accident-related injuries (n=183). Structural equation modeling was used to develop two models hypothesizing a relationship between PTSD symptomatology, pain severity, and perceived life control. Separate models were constructed for psychosocial and physical functioning, based on the hypothesis that pain and PTSD would be differentially related to disability in these two domains. Results suggested that more severe PTSD symptoms and greater pain complaints were related to psychosocial impairment, however, only pain was significantly related to impairment in physical functioning. Perceptions of life control were shown to further explain these interrelationships. © 2005 International Association for the Study of Pain. Published by Elsevier B.V. All rights reserved

Is the concept of repression useful for the understanding chronic PTSD?

Theories concerning the value of avoiding versus attending to trauma-related thoughts provide mixed support for specific coping strategies such as repression. The goal of this study is to examine the usefulness of the concept of repression in understanding chronic Posttraumatic Stress Disorder (PTSD). One hundred and fifty individuals who had been in a motor vehicle accident were included. Participants were classified into four groups (repressors, low anxious, high anxious, and defensively high anxious) based on methodology introduced by Weinberger et al. [J. Abnormal Psychol. 88 (1979) 369]. These four groups were compared on measures of PTSD symptomatology, anxiety, depression, and where appropriate, perceived pain and disability. Results revealed a fairly consistent pattern of group differences such that repressors reported fewer PTSD symptoms, fewer additional anxiety disorders, less depression, and less physical disability due to pain relative to the high anxious and defensively high anxious groups. Regression analyses examining the separate and interactive effects of anxiety and social desirability to predict PTSD symptomatology showed that the majority of the variance was explained by anxiety. In many respects, these data suggest that repression may not be a useful concept for understanding chronic PTSD. © 2003 Elsevier Ltd. All rights reserved

Exploring the effects of fitbit incentive on treatment outcomes in veterans undergoing intensive pain rehabilitation program

ObjectiveThis study compares clinical pain outcomes between patients in a pain treatment program that received a Fitbit, to patients that did not. We also explored: (1) cognitive, emotional, and psychological factors that may have impacted the decision to opt in to receiving a Fitbit; and (2) whether the choice to receive a Fitbit impacted changes in cognitive, emotional, and psychological factors following treatment.MethodsAmong 58 patients in a multidisciplinary pain treatment program at a Veterans Affairs Healthcare System hospital, 31 patients opted to receive a Fitbit as adjunct treatment, while 27 did not. This study utilized patient-reported and practitioner-collected data from the pain treatment program.ResultsCompared to the non-Fitbit group, the Fitbit group displayed a significant decrease in average pain intensity, however showed no correlation between Fitbit activity and average pain intensity. Additionally, treatment satisfaction was the only predictor of treatment group, when modeling pre- and post-treatment outcomes changes.ConclusionThe implementation of a Fitbit may lead to improved pain intensity. Initial evidence suggests that opting to receive a Fitbit during a pain treatment program indicates treatment engagement leading to greater treatment satisfaction. Future work is needed to verify and expand upon this potential mechanism

Screening for PTSD in motor vehicle accident survivors using the PSS-SR and IES

The current study compares the total scores of two potential posttraumatic stress disorder (PTSD) screening tools, the Impact of Event Scale (IES) and the PTSD Symptom Scale, Self-Report (PSS-SR), to the Clinician-Administered PTSD Scale (CAPS) in a large sample of motor vehicle accident (MVA) survivors (N = 229, of whom 43% met criteria for PTSD). For the IES using a cutoff score of 27, sensitivity was .91, specificity was .72, and overall correct classification was .80. For the PSS-SR using a cutoff score of 14, sensitivity was .91, specificity was .62, and overall correct classification was .74. Compared to those in studies of other trauma populations, the identified IES cutoff score is somewhat lower for this population of MVA survivors and the identified PSS-SR cutoff score is consistent with previous findings. These data support the use of the IES and the PSS-SR as PTSD screening tools in MVA samples. © 2006 International Society for Traumatic Stress Studies

Craving of prescription opioids among veterans with chronic pain.

The United States faces a crisis because of the high prevalence of chronic pain, concurrent opioid use disorder, and overdose deaths. Prescription opioids remain a primary driver of opioid-related deaths. Craving is a core symptom of addiction, yet the degree to which craving plays a role in prescription opioid use among patients with chronic pain is unknown. Understanding the degree to which craving should be considered in patients with chronic pain is critical for developing effective interventions for supporting patients through opioid tapering. The current work combines data collected from (1) 2152 veterans screened for eligibility at a pain specialty care clinic at the San Francisco VA Health Care System and (2) medical records obtained from the VA Corporate Data Warehouse. We found that prescription opioid craving among veterans with chronic pain was low, with 66.4% of the sample reporting no craving and 33.6% reporting craving. We also found that craving had a small association with morphine equivalent daily dose and pain severity but was more strongly associated with depression. Craving of prescription opioids among veterans with chronic pain is complex. Findings are discussed in relation to chronic pain symptoms, psychiatric comorbidities, and demographics

Understanding the interpersonal impact of trauma: Contributions of PTSD and depression

To build on the growing literature on interpersonal relationships among individuals with PTSD, this study examined the separate influences of PTSD symptoms and depression on functioning with friends, romantic partners, and family. To examine the influence of measurement, both interviewer-rated assessment of interpersonal functioning and self-reported assessment of perceived social support were included. The sample included 109 community members who sought help for mental health problems in the aftermath of a serious motor vehicle accident. Building on previous research, hierarchical regression models were used to examine the impact of re-experiencing, avoidance, emotional numbing, and hyperarousal on relationship functioning, followed by depression. Results suggest that assessment modality makes a difference in understanding factors contributing to interpersonal strain. When assessed by an interviewer, depression seems to play a larger role in interpersonal strain, relative to PTSD symptoms. When assessed via self-reported perceived social support, weaker associations were observed, which highlighted the role of emotional numbing. Results are discussed in light of the possible role that PTSD comorbidity with depression plays in interpersonal functioning following a traumatic event, with implications for future research. © 2008 Elsevier Ltd.
