What Is the Relationship Between Depressive Symptoms and Pain During Functional Tasks in Persons Undergoing TKA? A 6-year Perioperative Cohort Study.

Background: Preoperative depressive symptoms have been shown in some but not all studies to be associated with poor self-reported pain and function outcomes. In addition, depressive symptoms after surgery have been shown to improve relative to preoperative levels.

Questions/purposes: We hypothesized that (1) preoperative depressive symptoms would predict postoperative pain; (2) depressive symptoms would decrease after surgery; and (3) preoperative depressive symptoms would increase as the scheduled surgery date approached.

Effectiveness of abbreviated CBT for insomnia in psychiatric outpatients: sleep and depression outcomes.

Objective: To test the efficacy of cogntive-behavioral therapy for insomnia (CBT-I) as a supplement treatment for psychiatric outpatients. Comorbid insomnia is prevalent among individuals with varied psychiatric disorders and evidence indicates that CBT-I may be effective for reducing insomnia and other psychiatric symptoms.

Method: The present study randomly assigned 30 psychiatric outpatients (mean duration of treatment = 3.

Pain coping skills training for patients with elevated pain catastrophizing who are scheduled for knee arthroplasty: a quasi-experimental study.

Objectives: To (1) describe a behavioral intervention designed for patients with elevated pain catastrophizing who are scheduled for knee arthroplasty, and (2) use a quasi-experimental design to evaluate the potential efficacy of the intervention on pain severity, catastrophizing cognitions, and disability.

Design: Quasi-experimental nonequivalent control group design with a 2-month follow-up.

Setting: Two university-based orthopedic surgery departments.

Development of an abbreviated Social Phobia and Anxiety Inventory (SPAI) using item response theory: the SPAI-23.

An abbreviated version of the Social Phobia and Anxiety Inventory (SPAI) was developed using methods based in nonparametric item response theory. Participants included a nonclinical sample of 1,482 undergraduates (52% female, mean age = 19.4 years) as well as a clinical sample of 105 individuals (56% female, mean age = 36.

Electronic source materials in clinical research: acceptability and validity of symptom self-rating in major depressive disorder.

Objectives: Clinical research projects gather large amounts of data. Typically, information is captured on paper source documents for later transcription to an electronic format, where responses can be checked, and errors, omissions, and inconsistencies can be resolved. These steps contribute delays, cost, and complexity to clinical research, particularly in large-scale multi-site investigations.

Attentional bias to threat and emotional response to biological challenge.

Attentional bias towards threat reliably correlates with clinical anxiety status as well as elevated trait anxiety. Although such findings have led many to posit a potential causative or predictive role of threat-biased attentional processes on anxiety problems, little informative research exists. The present investigation was designed to address the role of threat-biased attentional processes on emotional/fearful responding.
