RESUMO
Trauma-focused psychotherapies, such as prolonged exposure (PE), are strongly recommended to treat posttraumatic stress disorder due to their effects in reducing symptoms. However, such therapies may also suffer from high dropout rates. To investigate how clients might benefit from trauma-focused therapy while minimizing dropout, we conducted a meta-analysis of 1,508 adults from 35 randomized controlled trials (RCTs) of outpatient PE programs to evaluate treatment frequency as a predictor of dropout. When an RCT prescribed PE sessions at least twice weekly compared to less frequently, the dropout rate was significantly lower at 21.0%, 95% CI [13.9%, 30.4%], compared to 34.0%, 95% CI [28.9%, 39.4%], OR = 0.52, 95% CI [0.30, 0.89], p = .018. It was not possible to draw causal conclusions, as only one RCT compared two PE treatment frequencies head-to-head. Nonetheless, the findings remained significant after controlling for study characteristics. These data invite reconsideration of the common practice of weekly psychotherapy in favor of twice-weekly sessions in standard outpatient treatment.

Mindfulness practice of present moment awareness promises many benefits, but has eluded rigorous behavioral measurement. To date, research has relied on self-reported mindfulness or heterogeneous mindfulness trainings to infer skillful mindfulness practice and its effects. In four independent studies with over 400 total participants, we present the first construct validation of a behavioral measure of mindfulness, breath counting. We found it was reliable, correlated with self-reported mindfulness, differentiated long-term meditators from age-matched controls, and was distinct from sustained attention and working memory measures. In addition, we employed breath counting to test the nomological network of mindfulness. As theorized, we found skill in breath counting associated with more meta-awareness, less mind wandering, better mood, and greater non-attachment (i.e., less attentional capture by distractors formerly paired with reward). We also found in a randomized online training study that 4 weeks of breath counting training improved mindfulness and decreased mind wandering relative to working memory training and no training controls. Together, these findings provide the first evidence for breath counting as a behavioral measure of mindfulness.

Tasks that tax working memory (WM) have consistently been found to decrease mind wandering. These findings may indicate that maintenance of mind wandering requires WM resources, such that mind wandering cannot persist when WM resources are being consumed by a task. An alternative explanation for these findings, however, is that mind wandering persists without the support of WM but is nonetheless decreased during any demanding task because good task performance requires that attention be restricted from task-unrelated thought (TUT). The present study tested these two competing theories by investigating whether individuals with greater WM resources mind-wander more during an undemanding task, as would be predicted only by the theory that WM supports TUT. We found that individuals with higher WM capacity reported more TUT in undemanding tasks, which suggests that WM enables the maintenance of mind wandering.

OBJECTIVE: The present study was conducted to identify factors that predict adherence to triptans by migraine patients. BACKGROUND: Triptans have demonstrated efficacy for acute migraine yet many migraine sufferers discontinue their use. DESIGN AND METHODS: A survey study was conducted using 785 subjects (390 health maintenance organizations [HMO] and 395 non-HMO). Of those, 586 were sustained users of triptans (defined by at least 1 refill within the past year), and 199 were classified as lapsed users (ie, individuals who had 0 refills in the past year). Groups were compared on a variety of measures including a comprehensive Migraine Survey that included items related to efficacy and adverse events associated with the patient's current medication, as well as the Headache Impact Test (HIT)-6 and Migraine Disability Assessment Score (MIDAS) questionnaires. Data were analyzed with multivariate analysis of variance and stepwise multiple regression. RESULTS: Sustained users of triptans were significantly more satisfied with their medication, confident in the medication's ability to control headache, and reported control of migraine with fewer doses of medication. Sustained users also switched triptans products significantly less often than lapsed users, and reported greater benefit from triptan intervention in restoring normal daily functions, including improved cognitive ability, compared with lapsed users' ratings of their nontriptan medication. More lapsed users than sustained users reported adverse events associated with past triptan use. Results from multiple and logistic regression analyses correctly classified 95% of sustained users and identified the most significant predictors for sustained use as: satisfaction and belief in medication, reliability of response, effectiveness in rapidly restoring normal levels of productivity, and fewer doses of medication for resolving an attack. The HIT-6 and MIDAS distinguished between sustained and lapsed triptan users on days unable to do household work and missed family and social events. CONCLUSIONS: Predictors of adherence to triptans included satisfaction and confidence in triptans' ability to stop the migraine and associated symptoms and to return the individual to normal functioning. The findings suggest that lapsed users may not be receiving optimal treatment, and that if their past response to triptans was a consequence of inadequate education, they may benefit from additional education on proper use of triptans.

In this paper, we summarize studies that used ANAM tests to assess the effects of environmental stressors. The findings document performance changes resulting from conditions relevant to military operational medicine. These conditions included radiation exposure, toxins, high altitude, undersea conditions, Marine basic training, advanced military training, and fatigue. The results of these studies demonstrate that ANAM detects cognitive changes in extreme environments.

A 4-year longitudinal study of the cognitive effects of the Chernobyl nuclear accident was conducted from 1995 to 1998. The controls were healthy Ukrainians residing several hundred kilometers away from Chernobyl. The exposed groups included Eliminators, Forestry workers and Agricultural workers living within 150 km of Chernobyl. Accuracy and efficiency of cognitive performance were assessed using ANAMUKR, a specialized subset of the Automated Neuropsychological Assessment Metrics (ANAM) battery of tests. Analyses of variance, followed by appropriate pairwise comparisons, indicated that the 4-year averaged levels of performance of the exposure groups (especially the Eliminators) were significantly lower than those of the controls on most measures; further, analyses of performance across time revealed significant declines in accuracy and efficiency, as well as psychomotor slowing, for all exposed groups over the 4-year period. These findings strongly indicate impairment of brain function resulting from both acute and chronic exposure to ionizing radiation.

This is a report of a study testing the capacity of a computerized measure of the content analysis of five minute verbal samples to detect and measure cognitive impairment and comorbid neuropsychiatric dimensions in 117 drug-abusing inpatients. The cognitive impairment scores obtained from the computerized procedure correlated significantly with independent scores from the Trails B and Stroop Color and Word test as well as with ANAM (Automated Neuropsychiatric Assessment Metric) neuropsychological tests, including the Matching to Sample Efficiency and Accuracy, the Code Substitution Efficiency, the Continuous Performance Task Efficiency and Accuracy, the Code Substitution Delayed Recall Accuracy, and the Simple Reaction Time Efficiency. When the computerized verbal-content-analysis-derived cognitive impairment scores were combined with scores of selected other ANAM measures, more and higher intercorrelations occurred with Trails A, Trails B, the Stroop Color and Word test, and the Wisconsin Card Sort test. In addition, validated measures of a broad range of associated neuropsychiatric dimensions can be obtained simultaneously from the same five minute verbal samples providing the cognitive impairment scores. No significant effects were found on the cognitive impairment scores of age, education, gender, race, and duration of drug-abuse abstinence.
