The use of the Brief Version of the Social Rhythm Metric in individuals with and without depression


Social Rhythm refers to the manifestation of regular daily activities, determined by social relations. People with depression have less stability in social rhythms and are generally more susceptible to the cognitive and somatic effects caused by breaking the rhythm. The Brief Version of Social Rhythm Metric (SRM) has been validated for the assessment of Social Rhythm in healthy adults. It consists of a self-administered questionnaire, which evaluates the performance of 6 daily activities (getting out of bed, talking to someone for the first time, starting work, having lunch, dinner and going to bed) and at what time they occurred.


To evaluate the use of the SRM in participants with and without depression.


This was a cross-sectional study with a sample of 36 patients (94.4% female), 36 controls (63.9% female), with a mean age of 45.14±15.75 and 45.61±15.27, respectively. The interviews took place in person at the Hospital de Clínicas de Porto Alegre (HCPA) and at the Hospital Materno Infantil Presidente Vargas (HMIPV), obtaining approval from the Ethics Committee of the two hospitals (HCPA nºGPPG: #2018-0437; HMIPV nºCAE: 57352416.0.0000.5329). Volunteers invited to participate in the study signed an informed consent form. The following questionnaires were applied: Sociodemographic Questionnaire, Beck Depression Inventory (BDI) and SRM. The last scale was completed for 15 days.


The preliminary results indicated that BDI score was 22.94±14.38 for patients and 5.78±3.96 for control group. In the patient group, only 61.1% of participants completed the scale correctly during 15 days, 19.4% partially completed and 19.4% did not complete the scale. For the control group, only 54.3% of participants completed the scale correctly, 11.1% partially completed, and 33.3% did not complete the scale.


The SRM proved to be a difficult scale to fill for both depressed and non-depressed individuals. Further studies are suggested to improve the definition and constructs of the Social Rhythm as well as its evaluation.
