RECRUITMENT
Once the informed consent form is signed and the baseline questionnaires (T0 and T1) are completed, the randomization procedure begins. Participants are randomly assigned to either a control or an experimental group with a 1:1 allocation according to a computer-generated randomization schedule stratified by sex (male or female) and psychiatric diagnoses and using permuted blocks of random sizes. The block sizes will not be disclosed to ensure concealment. Participants will be randomized using randomization.com, an online randomization tool. Allocation concealment will be ensured because the person who performs randomization has no other role in the study. This person will prepare the randomization lists and seal the envelopes. The randomization code will not be released until the participant is recruited into the trial, which occurs after all baseline measurements have been completed.To ensure allocation concealment, the steps involved in randomization, outcome measurements, and treatment are separated. Participants who meet the inclusion criteria and provide consent for participation will be randomized. Research assistants responsible for recruitment and outcome measurement will request randomization.
