To evaluate the effectiveness of the PERSISTANCE Disease Management program on:
PERSISTANCE, a pragmatic randomized controlled trial, will be conducted among workers aged 18 to 64 years and who have begun an antidepressant treatment for depression or generalized anxiety. Employees will be recruited in pharmacy or in companies that participate in the research project. Like most evaluation studies, participants will be randomized (by chance) to one of the following groups :

Patients randomized to the PERSISTANCE group will receive the complete program (telephone follow-up, information modules, feed-back letters to the physician) whereas patients randomized to the usual care group, will have a telephone interview at registration, will be contacted at six months and receive the information modules then as well. It should be noted that even though patients in the usual care group do not have the same intensity of follow-up, they will recieve more information than what is available right now through the health care system. Patients will be informed of this randomization process in the consent form which they will need to sign prior to enrollment.
The study is conducted in collaboration with Quebec enterprises and pharmacist. Employees will be informed of the PERSISTANCE research study by their pharmacist, posters placed in strategic locations within the company, or through internal communications (intranet). Employees must register to become part of the program and send us via fax their signed consent form. The consent form explains the study and what their participation entails. Employees are guaranteed confidentiality and that no information will be given to a third party, not their employer, nor their insurance company. Their participation involves telephone interviews at home or during work breaks. Each interview will last approximately 30 to 60 minutes.
