The power of appraisals in predicting PTSD symptom improvement following cognitive rehabilitation: A randomized clinical trial.

Background: Patients with PTSD often voice concern over their perceived change in cognitive functioning. However, these negative appraisals do not always align with objective neuropsychological performance, yet are strongly predictive of PTSD symptom severity and self-reported functional impairment.

Methods: The present study involves a secondary analysis examining the role of appraisals of a subsample of 81 adults with full or subthreshold PTSD on treatment outcomes in a randomized controlled trial investigating the effectiveness of a cognitive rehabilitation treatment, Strategic Memory and Reasoning Training (n = 38), compared to a psychoeducation control arm, the Brain Health Workshop (n = 43).

Cognitive Training for Mild Traumatic Brain Injury and Posttraumatic Stress Disorder.

Although there is evidence of mild cognitive impairments for many individuals with mild traumatic brain injury (mTBI) and posttraumatic stress disorder (PTSD), little research evaluating the effectiveness of cognitive training interventions has been conducted. This randomized controlled trial examined the effectiveness of a 9-h group cognitive training targeting higher-order functions, Strategic Memory Advanced Reasoning Training (SMART), compared to a 9-h psychoeducational control group in improving neurocognitive functioning in adults with mTBI and PTSD. A sample of 124 adults with histories of mild TBI ( = 117) and/or current diagnoses of PTSD ( = 84) were randomized into SMART ( = 66) or Brain Health Workshop (BHW; = 58) and assessed at three time points: baseline, following training, and 6 months later.

Is Amazon's Mechanical Turk (MTurk) a comparable recruitment source for trauma studies?

Objective: Trauma researchers have recently begun using Amazon's Mechanical Turk (MTurk) as a data collection platform that is both time- and cost-efficient. Research is needed to determine the utility, generalizability, and validity of MTurk as a recruitment source for trauma-exposed samples.

Method: Data were collected from 266 trauma-exposed MTurk participants on several clinical and psychological constructs relevant to trauma research.
