Biased attention allocation in major depressive disorder: A replication and exploration of the potential effects of depression history.

Background: Increased attention allocation to negative-valenced information and decreased attention allocation to positive-valenced information have been implicated in the etiology and maintenance of depression. The Matrix task, a free-viewing eye-tracking attention assessment task, has shown corroborating results, coupled with adequate reliability. Yet, replication efforts are still needed.

The effects of intelligence on exposure to combat and posttraumatic stress disorder across multiple deployments.

Introduction: Past work relates intelligence quotient (IQ) to risk for Post-Traumatic Stress Disorder (PTSD) among soldiers. We gathered data over multiple deployments to assess how IQ relates to the rate of symptom development both directly and through increasing the risk for traumatic combat exposure.

Methods: Male infantry soldiers from a maneuver brigade (N = 582) were followed over the 3-year period of their mandatory military service.

Neural activation changes following attention bias modification treatment or a selective serotonin reuptake inhibitor for social anxiety disorder.

Background: Delineation of changes in neural function associated with novel and established treatments for social anxiety disorder (SAD) can advance treatment development. We examined such changes following selective serotonin reuptake inhibitor (SSRI) and attention bias modification (ABM) variant - gaze-contingent music reward therapy (GC-MRT), a first-line and an emerging treatments for SAD.

Methods: Eighty-one patients with SAD were allocated to 12-week treatments of either SSRI or GC-MRT, or waitlist (s = 22, 29, and 30, respectively).

Interpreting PPV and NPV of Diagnostic Tests with Uncertain Prevalence.

Objective: Medical decision-making is often uncertain. The positive predictive value (PPV) and negative predictive value (NPV) are conditional probabilities characterizing diagnostic tests and assessing diagnostic interventions in clinical medicine and epidemiology. The PPV is the probability that a patient has a specified disease, given a positive test result for that disease.
