Moderators of Outcome in Problem-Solving Therapy for Depression in Primary Care
1Department of Psychology, Washington State University, Vancouver, Washington.
Objective:
The purpose of this study was to conduct a secondary analysis of data from trials of problem-solving therapy in primary care (PST-PC) to examine differential outcomes by gender or race-ethnicity.
Methods:
The participants were 352 patients with depression treated with PST-PC in multiple primary care sites in the United States.
Results:
Women's depressive symptoms improved more over time than men's. Hopkins Symptom Checklist depression scale scores decreased significantly (t=-10.12, df=692, p<0.001) (estimate=-0.02, 95% confidence interval=-0.03, -0.02). Although patients from racial-ethnic minority groups had more depressive symptoms over time than patients from nonminority groups, there was no evidence of differential change by racial-ethnic group.
Conclusions:
These data add to the literature supporting the usefulness of PST-PC without evidence of differential effects for patients from racial-ethnic minority or nonminority groups.

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
