Modern tuberculosis intervention emphasizes patient compliance with a medical regimen, but it neglects the need to change socioeconomic factors that contribute to the persistence of this disease. Currently, social workers rarely work with tuberculosis patients, although social work methods may be more appropriate for groups who resist the medical approach. Three models of social work intervention with a primarily black, low-income, tuberculosis population are described. The models emphasize community organization, case consultation, and medical social work methods, respectively.

SUMMARYA ‘control’ provides a point of clinical comparison for a new intervention, allowing researchers and clinicians to draw more confident conclusions about the effectiveness or potential harm of a given, often novel, therapy. Although this aspect of a trial's design provides the basis from which interventional impact is measured, it is often less closely examined. This commentary appraises a Cochrane Review that compares various controls in common use in modern psychiatric research and aims to characterise their effects on the outcomes of that research.
