Study Details

Study Description

Brief Summary

This is an observational study where digital, clinical and health utilization data are collected from individuals with schizophrenia spectrum disorders who have been recently discharged from a psychiatric hospitalization. The data will be used towards building a model/algorithm capable of monitoring mental health and predicting adverse clinical events, such as relapse and re-admissions.

Condition or Disease Intervention/Treatment Phase
  • Other: Observational

Detailed Description

In this research, participants will attend 6-weekly follow-up research visits (Weeks 0, 6, 12, 18, 24) over 24 weeks where clinical symptoms, cognition, functioning and well-being will be assessed. Passive digital data from smartphones and wrist wearable devices (e.g. sleep patterns, heart rate, location variance and entropy, phone usage frequency and duration, finger taps, ambient light, and physical activity) will be collected continuously during the 24 weeks. Audio recorded follow-up phone calls will be made to participants who consented to the optional audio recorded component at Weeks 3, 9, 15, 21. This study will also carry out an administrative follow-up at Week 24/termination and Week 52 to obtain healthcare utilization information (e.g. scheduled or unscheduled appointments, readmission, etc) since study enrollment.

Study findings will shed light on the relationship between digital biomarkers with clinical status and health utilization outcomes, as well as explore the feasibility and acceptability of digital sensors.

Arm Intervention/Treatment
Participants with schizophrenia spectrum disorders

Within 8 weeks post discharge from hospitalization at the Institute of Mental Health

Outcome Measures

Primary Outcome Measures

  1. Clinical Global Impression scale - Severity [up to 24 weeks]

    A single item measuring severity of illness at the point of assessment relative to a clinician's experience with patients of the same diagnosis on a 7-point scale; a higher rating indicates greater severity.

Secondary Outcome Measures

  1. Positive and Negative Syndrome Scale [Week 0, 6, 12, 18, 24]

    A 30-item clinical scale measuring positive symptoms, negative symptoms and general psychopathology. A higher total score indicates greater symptom severity.

  2. Brief Negative Symptom Scale [Week 0, 24]

    A 13-item scale that measures five negative symptom domains (blunted affect, alogia, asociality, anhedonia and avolition) and a subscale on Lack of Normal distress. Higher total score indicates greater negative symptoms.

  3. Calgary Depression Scale for Schizophrenia [Week 0, 6, 12, 18, 24]

    CDSS is a scale designed for the assessment of depression in schizophrenia, which differentiates between depression and the negative and positive symptoms of schizophrenia. Higher total score reflects greater severity.

  4. Clinical Global Impression scale - Improvement [Week 6, 12, 18, 24]

    A single item which measures how much the patient's illness has improved or worsened relative to a baseline state on a 7-point scale. A higher rating indicates greater worsening of illness.

  5. Brief Adherence Rating Scale [Week 0, 6, 12, 18, 24]

    A clinician-administered instrument to assess oral antipsychotic medication adherence of outpatients with schizophrenia. Greater proportion of doses taken in the past month indicate greater adherence (range: 0%-100%).

  6. Columbia Suicide Severity Rating Scale [Week 0, 6, 12, 18, 24]

    A scale assessing both suicidal ideation and behaviour.

  7. Social and Occupational Functioning Assessment Scale [Week 0, 6, 12, 18, 24]

    A scale designed to evaluate an individual's level of social and occupational functioning; its rating is not directly influenced by the overall severity of the individual's psychological symptoms. A greater rating reflects superior functioning in various areas of life (range: 0-100).

  8. Brief Assessment of Cognition in Schizophrenia [Week 0, 24]

    A cognitive battery which assesses attention, verbal and working memory, motor and processing speed, verbal fluency, reasoning and problem solving. Higher composite score indicates better cognitive function.

  9. 5-level EQ-5D [Week 0, 12, 24]

    A standardized instrument developed as a measure of health-related quality of life that can be used in a wide range of health conditions and treatments. A higher score indicates best health imagined (range: 0-100).

  10. Subjective Well-being under Neuroleptics scale - short form [Week 0, 24]

    A self-rated instrument to assess well-being from a patient's perspective based on their subjective experiences during antipsychotic treatment. Higher total score indicates greater well-being.

  11. Acceptability questionnaire [Week 24 or termination visit]

    This questionnaire consists of an item measuring participants' satisfaction based on their experience of using digital devices on a scale range of 1 (Strongly disagree) to 7 (Strongly agree). Two other qualitative items in this questionnaire gather feedback on the strengths and suggested improvements for the system and user satisfaction.

  12. Healthcare Utilization [12 months]

    Data from IMH's medical records which document events such as scheduled appointments, defaults, E-room attendances and hospitalizations will be used to explore healthcare utilization and its relationship with digital biomarkers.
