Plain English Summary

Background and study aims
Making sure major depressive disorder (MDD) patients take their antidepressant treatment (adherence to medication) is essential in managing their condition. Adherence to medication is a dynamic decision-‎‎making process, and pharmacists play an important role in improving adherence to ‎‎antidepressant treatment in different settings within the health care system. Shared decision making (SDM) is a conversation between a patient and a healthcare professional whereby decisions are made about a patients treatment, taking into account what is important to both parties. Here, we want to test a pharmacist intervention (programme) based on SDM‎‏ ‏to see whether it improves adherence to medication and, ultimately, how successful the treatment is at treating MDD.

Who can participate?
Adults (aged between 18-60) newly diagnosed with MDD.

What does the study involve?
Patients are randomly allocated into one of two groups. Those in group 1 (intervention group) attend a SDM session with a pharmacist which focused on improving the patients involvement in decision ‎making, their beliefs towards antidepressants and their knowledge about ‎antidepressants‎. Those in group 2 do not attend a SDM session. Adherence to medication, severity of depression, health-related quality of life, patient satisfaction and the patients beliefs about medicine is assessed for all participants at the start of the study, 3 months after the study begins and then again at 6 months.

What are the possible benefits and risks of participating?
The study was designed to minimize any potential risks to the patients. Participants may benefit from intervention conducted in this study.

Where is the study run from?
Al Amal Hospital (Saudi Arabia)

When is the study starting and how long is it expected to run for?

Patients diagnosed with major depression disorders


The intervention focused on the enhancement of the patients’ involvement in decision ‎making, their beliefs towards antidepressants and their knowledge about ‎antidepressants‎.

Pharmacists followed the SDM competency framework proposed by Simmons et al, which was designed specifically for depressed patients, to ensure the coverage of all aspects of SDM for each patient. Before the SDM session started, the research team distributed a decision aid, which was developed and validated by Aljumah et al. and was specified for Arabic-speaking patients, to patients in the intervention group (IG). The intervention focused on the enhancement of the patients’ involvement in decision making, their beliefs towards antidepressants and their knowledge about antidepressants. The average time for the first SDM session (at baseline) was 15 minutes and 10 minutes for the remaining SDM sessions.

A simple randomisation process was used. Study participants were individually randomised to one of two parallel groups with an allocation ratio of 1:1 using a computer-generated list. The computer-generated allocation was done by a research assistant with no clinical involvement in the trial. Pharmacists and psychiatrists were not blinded to the patients’ distribution between groups. The research assistant who collected all the data was blinded to the distribution of patients
