This first controlled psychotherapy trial for seasonal affective disorder (SAD) compared SAD-tailored cognitive-behavioral therapy (CBT), light therapy (LT), and their combination to a concurrent wait-list control. Adults (N = 61) with major depression, recurrent with seasonal pattern, were randomized to one of four 6-week conditions: CBT (1.5-hr twice-weekly group therapy), LT (10,000-lux for 90-min/day with administration time individually adjusted), combined CBT + LT, or a minimal contact/delayed LT control (MCDT; LT following 6 weeks of monitoring). CBT, LT, and CBT + LT significantly and comparably improved depression severity relative to MCDT in intent-to-treat and completer samples. CBT + LT (73%) had a significantly higher remission rate than MCDT (20%). Using prospectively measured summer mood status to estimate the "functional" population, CBT + LT also had a significantly larger proportion of participants with clinically significant change over treatment compared with MCDT. The LT condition outcomes virtually replicated results from prior trials. CBT, alone or combined with LT, holds promise as an efficacious SAD treatment and warrants further study. If replicated, CBT + LT's remission rate would represent a clinically meaningful improvement over the 53% observed across LT studies.

Background: The need to develop supplementary or alternative treatments for seasonal affective disorder (SAD) is underscored by the significant minority (47%) of SAD patients that is refractory to light therapy, the persistence of residual symptoms despite light treatment, and poor long-term compliance with light use. Because preliminary studies suggest that cognitive and behavioral factors are involved in SAD, cognitive-behavioral therapy (CBT) warrants investigation as a possible treatment option. Methods: We piloted a 6-week randomized clinical trial to compare a standard light therapy protocol; a novel, SAD-tailored, group CBT intervention; and their combination in ameliorating and remitting a current SAD episode and as prophylaxis against episode recurrence. Depressive symptom severity and remission rates were assessed at post-treatment and at a 1-year follow-up visit to examine long-term treatment durability. Results: CBT, light therapy, and their combination all demonstrated significant reductions in depressive symptoms on two different outcome measures. Remission rates varied by measure, but did not reach statistical significance. During the subsequent winter, CBT, particularly in combination with light therapy, appeared to improve long-term outcome regarding symptom severity, remission rates, and relapse rates. No CBTtreated participant, with or without light, experienced a full SAD relapse compared to over 60% of those treated with light alone. Limitations: These results should be viewed as preliminary and are limited by the small sample size (n=23) and lack of a control group. Conclusions: The nearly half of SAD patients who do not remit with light alone may benefit from CBT as an adjunct or alternative treatment, especially as a prophylaxis against episode recurrence.

In the past 20 years, several cases have been reported describing an upper airway obstruction reportedly caused by psychological factors. This paper reviews 48 reported cases of "psychogenic stridor." Patients with psychogenic stridor usually present to primary care physicians with symptoms of asthma or stridor unresponsive to conventional treatments. Of the 48 cases reviewed, 52% received a diagnosis of conversion disorder. The obstruction was severe enough to cause intubation and tracheostomies in some patients. In addition, many suffered from the unnecessary side effects of corticosteroids. The literature is reviewed and medical and psychiatric differential diagnosis and treatment are discussed.

Changes in psychiatric health care delivery driven by such major shifts as deinstitutionalization, community-based care, and managed care have greatly altered the educational milieu for third-year psychiatry clerkships. Students may be assigned exclusively to alcohol and substance abuse treatment units, consultation-liaison services, or outpatient clinics, and may not have as broad an exposure as is desirable to patients with a variety of psychiatric illnesses. The authors describe a pilot course they developed in 2001, Clinical Psychiatric Assessment and Diagnosis, for third-year medical students at the Uniformed Services University of the Health Sciences medical school. The course uses standardized patients (SPs) to help students gain broader clinical experience. In psychiatry, a growing body of literature supports the acceptability, reliability, and validity of objective structured clinical examination assessment using SPs for medical students. Only a few articles report the use of SPs to primarily teach psychiatry instead of evaluating student proficiency in clinical psychiatry. Since this course was developed, the National Board of Medical Examiners announced that all medical students will be required to pass a clinical skills test in order to practice medicine, beginning with the class of 2005. The examination will use SPs modeling different clinical scenarios. In light of this change, many medical schools may have to reevaluate and possibly revamp their curriculums to insure sufficient acquisition of clinical skills in different specialties. The use of SPs in psychiatry could provide an effective, primary clinical teaching experience to address this new requirement as well.
