Early Intervention for Mental ϱ and Substance Use Among Children and Youth Indicator
Higher is better. The higher the result, the higher the number of individuals with early needs who accessed community-based mental health and substance use services.
(Total number of individuals age 13 to 24 who’d accessed at least one of the defined community MHSU services [Q5] in the past 6 months ÷ the total number of individuals who had early MHSU needs [Q1–4] in the past 6 months) × 100
This measure assesses access to early intervention for mental health and substance use issues in individuals age 13 to 24.
Note: Data from Quebec includes individuals age 14 to 24.
Note: Early MHSU needs are defined as experiencing self-reported mild to moderate functional impairment (Q3) or a perceived need for care (Q4) in relation to MHSU issues.
Q1. In the past 6 months, have there been any issues or concerns in your mental health and substance use? Such as changes in your mood, feelings of sadness, anxiety or irritability, or your use of alcohol or drugs?
Q2. Were the mental health or substance use issues or concerns that you experienced over the last 6 months new, or were they previous issues or concerns that got worse, got better or stayed the same?
Q3. How difficult have these issues or concerns made it for you to do your work or school work, take care of things at home or get along with other people?
Q4. In the past 6 months, was there ever a time that you or others felt you might need help to deal with issues or concerns in your mental health and substance use?
Q5a to h. In the past 6 months, did you access any of the following services provided by someone trained in mental health and substance use support?

Methodology
Name
Early Intervention for Mental ϱ and Substance Use Among Children and Youth
Short/Other Names
Not applicable
Description
Proportion of individuals age 13 to 24 with early mental health and substance use needs who accessed community-based mental health and substance use services in the last 6 months.
Early mental health and substance use needs are defined as new or pre-existing self-reported functional impairment (working or doing school work, taking care of things at home or getting along with other people) or a perceived need for care in the last 6 months. Children and youth who reported severe impairment with an onset prior to the last 6 months were excluded.
Rationale
This indicator provides an indirect measure of whether children and youth in Canada are accessing early intervention services when they are experiencing mild to moderate MHSU issues. This indicator focuses on the age of onset for a variety of major mental health disorders and provides a picture of access to MHSU services that apply to multiple symptoms and disorders. Early interventions can help reduce the symptoms and severity of the issues and may help delay progression to a diagnosed disorder.
Early intervention occurs in a variety of community settings, and this indicator focuses on access to formal services (i.e., those with a mandate to provide MHSU services to children and youth).
Interpretation
Higher is better. The higher the result, the higher the number of individuals with early needs who accessed community-based mental health and substance use services.

Method of Adjustment
Sample weight
Adjustment Applied
Covariates used in risk adjustment:
The initial weights were created using a methodology that incorporates weighted totals calculated from the probabilistic weights of a survey (i.e., the Canadian Community ϱ Survey [CCHS]) from which the target population could be extracted. The raking method was used to calibrate the initial weights in the survey based on provincial target populations in the CCHS. Weight raking was performed for reportable provinces only.

Caveats and Limitations
Survey results should be considered only representative of the surveyed population. The survey was conducted in a way that not everyone in the population had an equal chance of participating (non-probabilistic sampling). The use of social media recruitment and non-probabilistic sampling resulted in selection and participation bias. Weighting methods were used to reduce bias, but the following limitations should be noted:
- The survey was available in English and French. People who did not speak either of these languages were not able to complete the survey. Language barriers may also impact survey results, as the experience of accessing mental health and substance use services may differ for people who do not speak English or French.
- Those without internet access did not have the same opportunity to participate in the survey (non-coverage bias).
- Participants may have been influenced by the recruitment strategy and the incentive, resulting in selection and participation bias. For example, there might be an underrepresentation of certain age groups or genders that are less likely to be reached through social media recruitment.
- Assessing mental health and substance use services in the previous 6 months is subject to the individual’s ability to remember their experience (recall bias).
- Low response rates from participants who were 13 to 18 years old may be a result of social media recruitment and the required age for social media accounts.
Early intervention occurs in a variety of community settings, and this indicator focuses on access to formal services (i.e., those with a mandate to provide mental health and substance use services to children and youth). Informal supports are outside the scope of the indicator and are not included. Emergency department visits and inpatient hospital stays are also out of scope.
Results for 2024 will be reported at a national level only due to insufficient data.
