Assessing the Effectiveness of Psychiatric Interventions on the Inpatient Unit

This study will monitor the symptoms of patients who have received an intervention on the psychiatric inpatient unit at Stanford hospital up to 6 months after they have received the intervention. Additionally, the acceptability and feasibility of interventions will be assessed using clinician and patient questionnaires.

Once patients have been discharged from hospital they will be contacted weekly for 4 weeks and then every 2 weeks until 6 months post-intervention in order to monitor their symptoms. Participants will be followed up until the end of the study (6 months after the intervention) or until they no longer meet responder criteria (MADRS score\>50% of score before they received the intervention) During the follow-ups for the first 8 weeks, the following assessments will be conducted: Montgomery-Åsberg Depression Rating Scale (MADRS) Scale of suicidal ideation (SSI) Hamilton depression rating scale (HAMD-6) Young Mania Rating Scale (YMRS) Pittsburgh insomnia rating scale (PIRS-20) Quick inventory of depressive symptomatology (QIDS) Immediate Mood Scaler (IMS-12) Beck Depression Inventory (BDI-II) C-SSRS self-report short version

Quality of Life Enjoyment and Satisfaction Questionnaire - Short Form (Q-LES-Q-SF) will be collected at one month post-intervention.

If the participant has a psychiatric diagnosis(/es) other than MDD, questionnaires measuring the symptoms associated with the participant's other psychiatric diagnosis/(es) will also be administered.

Follow-up assessments from 10-24 weeks will include:
