Relationship between homework completion and outcome in cognitive behaviour therapy.

Homework or between-session learning has long been considered an essential aspect of effective cognitive behaviour therapy. However, it has received relatively less empirical attention than other components of cognitive behaviour therapy. In general, studies have found that homework completion is predictive of outcome in psychotherapy. However, the amount of homework completed by a patient represents only one aspect of this important therapeutic component. This study investigated both the quantity and the quality of homework completed during a 10-week group cognitive and behavioural treatment program for anxious and depressed patients. It explored the relationship between various aspects of homework completion and outcomes on several different variables. A total of 94 patients were included in the analysis. It was found that both quantity and quality of homework completed predicted outcome on measures of depression, anxiety and quality of life at post-treatment and at 1-month follow-up. The results were strongest for the amount of homework completed, suggesting that clinicians should encourage patients to complete homework even if the homework content is not entirely accurate. The results of this study highlight the importance of homework as a central part of effective cognitive and behavioural treatment.

Diagnosis of Strongyloides stercoralis in a peritoneal effusion from an HIV-seropositive man. A case report.

BACKGROUND: Strongyloides stercoralis, a nematode parasite in humans with free-living and autoinfective cycles, is often an asymptomatic infection of the upper small intestine. If the host becomes immunocompromised, autoinfection may increase the intestinal worm burden and lead to disseminated strongyloidiasis. The parthenogenetic adult female larvae can remain embedded in the mucosa of the small intestine for years, producing eggs that develop into either rhabditiform, noninfective larvae or filariform, infective larvae. Manifestations of dissemination occur when the filariform larvae penetrate the intestinal wall and migrate into the blood. Pulmonary involvement is common, and the central nervous system may be affected. Blood eosinophilia is typical, and gram-negative sepsis from enteric bacteria may occur. Much less commonly described is invasion of the peritoneal cavity with peritoneal effusion. CASE: A 49-year-old man who came to the United States from Liberia 4 years earlier presented with sudden onset of severe abdominal distention, generalized weakness and marked pedal edema. Diagnostic paracentesis showed numerous filariform larvae of S stercoralis. Stool examination confirmed the presence of both rhabditiform and filariform larvae. Subsequently the patient was found to be HIV seropositive, with a CD4 lymphocyte count of 59. CONCLUSION: Early detection of S stercoralis may alter the often-fatal course of infection. The present case is the second reported one in the English-language literature of the diagnosis of S stercoralis in ascitic fluid.
