DESIGN OF RANDOMIZED CLINICAL TRIALS IN PSYCHOLOGY, PSYCHIATRY, AND THE CLINICAL NEUROSCIENCES

The Brown Quantitative Science Program offers an occasional seminar series in methods in psychiatry, psychology, neurology and clinical neurosciences. Participation is open. Typical participants are those fulfilling training plans for K or other career development awards. Participation means reading articles ahead of the seminar, completing an occasional assignment, and participating in the discussion.

This winter, we will be holding a seminar on the Design of Randomized Trials (QSP-04). This is an 8 session series. The schedule and syllabus can be viewed at https://dl.dropbox.com/u/458793/Professional/QSP04-2017.pdf

There are a limited number of seats left if anyone is interested in attending and available for most of the seminar dates.

- Both males and females should be included
- At a minimum, plan for presentation of results in a sex-stratified way

Does not necessarily mean
- must hypothesize and have adequate power to test for main or modification effects by sex

Satisfaction of this criterion does influence overall score
