What this study is about

Behavioural Development, Long-term Outcomes and Opportunities to Optimize Youth Mental Health (BLOOM) is a project that aims to overcome age and diagnostic boundaries to generate person-specific longitudinal profiles of mental health in youth aged 9 to 25. The overarching objective is to lay the informational foundation to accurately predict both clinical outcomes and opportunities to optimize health trajectories. This project will recruit youth in need without any mental health diagnosis and follow them annually for 5 years. The present study includes assessment of antecedents, opportunities and outcomes that will establish eligibility for preventive interventions

Who can join (things the study team will check)

Due to the requirements of assessment procedures, youth who cannot communicate verbally due to known neurological conditions or intellectual disabilities will not be included. Youth who are already diagnosed with one of the DMDs by a physician and currently prescribed a treatment targeting the diagnosed condition (pharmacological or psychotherapeutic interventions), will not be eligible for inclusion. Importantly, no one will be excluded based on sex, gender, health insurance status, ethnicity, income status, ability to travel or living arrangements. If a participant initially approached through the referral pathways for non help-seeking individuals turns out to have had at least one help-seeking contact for a mental health concern (i.e., clinical needs), the participant will still be included but classified as part of the help-seeking group. We anticipate non help-seeking referrals to satisfy more than one criteria. Their occurrence and distribution will be recorded in detail as part of our assessment procedure.
