Cohort Network for Adolescents and Youth With multipLe Mental Health Conditions (CALM)

Cohort Network for Adolescents and Youth With multipLe Mental Health Conditions (CALM): A Master Observational Trial

The Cohort Network for Adolescents and Youth With multipLe Mental Health Conditions (CALM) Master Observational Trial is a prospective, longitudinal observational study that seeks to improve clinical care for youth with multiple mental health conditions (MMHC), also known as mental health multimorbidity in the literature. MMHC is conceptualized as the presence of two or more mental health diagnoses under the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). MMHC is common in youth seeking mental health services and is associated with less favorable outcomes and greater health services utilization. Mental health disorders also accumulate in youth over time. The Master Observational Trial (MOT) will investigate MMHC in critical developmental periods in youth and identify risk and protective factors that will provide a mechanistic understanding of how MMHC develops over time. A subset of participants will also enroll in a Deep Phenotyping Cohort, which includes enhanced clinical and cognitive assessments and multimodal neuroimaging to investigate neurobiological mechanisms underlying MMHC and identify potential biomarkers of illness complexity and progression.

In the near future, we aim to add to the current protocol to embed both a clinical trials network for youth mental health in Ontario and Calgary within the CALM study and add digital phenotyping using wearable technology to generate digital and physiological markers of MMHC. The current protocol focuses on establishing the longitudinal MOT cohort and Deep Phenotype Cohort only as a first step towards these long term CALM goals.

Detaljeret beskrivelse

The primary objectives of the CALM MOT are to:

  1. Establish a prospective, longitudinal cohort of children and youth aged 11-24 years to characterize the progression and outcomes of MMHC over time.
  2. Facilitate later development of a clinical trials network and clinical research in MMHC with a focus on developing transdiagnostic interventions and improving care.
  3. Establish a deeply phenotyped cohort of youth in a subset of participants enrolled in the MOT (light phenotyping protocol), using multidimensional, multilevel data to investigate brain-based mechanisms of MMHC with potential for biomarker discovery.

Specific objectives of the Deep Phenotyping Cohort are to:

  1. Collect data across CALM sites in participants that are eligible and consent to participate in CALM MOT Light and the Deep Phenotyping Protocol. In this subset of CALM participants, we will extend the clinical/behavioural measurement battery, and collect high quality cognitive and multimodal (T1, multi-shell DWI, resting state, ASL) neuroimaging data that will be undertaken as part of the CALM baseline deep phenotyping protocol.
  2. Use open access brain age and centile score calculators using unimodal brain imaging data to examine centile score distributions for various data samples in a sex stratified manner (e.g., clinical/community ascertained) and associations between centile scores with behavioral/cognitive indices of clinical severity/impairment and MMHC (e.g., MMHC index). Available open access normative and clinically enriched neuroimaging samples that overlap with the proposed CALM sample age range (11-24 years) will be utilized.
  3. Undertake analysis using cross-sectional neuroimaging and longitudinal MOT data derived from the CALM network to test whether deviations from normative brain measures using either unimodal or integrating data from different imaging sequences (i.e., multimodal), imaging calculators may have utility as a baseline 'prognostic/predictive' marker of youth who may have more complex illness (i.e., MMHC) at the time of initial (baseline) participation in the CALM study and at subsequent time points and/or may be less responsive to clinical interventions.

Studiebefolkning

The CALM network will recruit children and youth aged 11-24 who have sought, are seeking, or are accessing mental health care from 5 partner sites in Ontario (Centre for Addiction and Mental Health, Hospital for Sick Children, McMaster Children's Hospital, Children's Hospital of Eastern Ontario, and The Royal Ottawa Mental Health Centre) and 1 partner site in Alberta (Alberta Health Services) as well as the broader community.

Caregivers of CALM participants will be asked to complete caregiver specific questionnaires (self-report and completing the measures based on their child/youth). When a CALM child/youth participant is approached for the study, we will ask said participant if we can contact their caregiver to participate in the study. We will then approach the caregiver for consent. No external recruitment of non-CALM participants caregivers will be implemented.

MOT

In the MOT/Light Protocol, clinical, and functional measures will be collected in addition to blood-based 'omics' including proteomic (immune markers) and genomic analysis of DNA derived from blood and/or saliva. Over 3 years n=1620 children and youth will be recruited to the MOT/Light Protocol across the CALM Network.

A number of measures will be collected throughout the course of the study in order to capture symptoms across a spectrum of conditions in the target population. Provided that the main objective of the CALM project is to improve clinical care for youth with a particular focus on MMHC, it is vital to use validated standardized assessments that test highly prevalent physical and mental health conditions. MOT/Light measures will be collected via self-report (SR), rated-administered (RA), caregiver-administered (Ca), or a combination
Deep Phenotyping
Multidimensional, multilevel data will be obtained in a subcohort of CALM Study youth (3 years n=~614) recruited to the MOT who also consent to participate in the Deep Phenotyping protocol. The Deep Phenotyping Protocol includes additional clinical, behavioural, developmental and functional outcomes, not collected as part of the light phenotyping battery as well as the collection of neurocognitive measures and neuroimaging data. Cognitive phenotyping will be administered at 0 and 6 month time points. Neuroimaging will be collected at one time point, harmonized across sites using human connectome quality scanning and to key external initiatives (e.g., neuroimaging via ABCD) facilitating secondary data use, and the utilization of additional cohorts in analysis.
