Mental Health: Screening Tools and Rating Scales

To help paediatricians and other child health care providers recognize and diagnose mental health problems, the Canadian Paediatric Society has compiled a list of screening tools and rating scales for a number of different symptoms and suspected conditions.

Paediatric experts were asked what screening tools and rating scales they use on a regular basis. Members of the CPS Mental Health and Development Disabilities Committee considered many different tools. Each instrument was rated on a series of criteria including:

  • age range to which it applies,
  • time required to complete,
  • who completes the questionnaire,
  • accuracy,
  • cost, and
  • whether the tool allows co-morbidities to be identified.

The tool(s) you choose will depend on your clinical setting, your practice support, and the nature of your patients. Some of the tools and scales are also designed to monitor certain conditions rather than diagnose them. The CPS has selected tools that should be most efficient and usable for paediatricians. You may download the full list of tools, or select only those areas of most interest to you.

Preliminary Mental Health Screening Tools

These provide a starting point to investigate suspected mental health conditions and help focus further assessment. They are helpful in screening for co-morbidities, but less helpful in making a diagnosis of a specific condition. Because they screen for a wide range of mental health conditions, they tend to be quite lengthy.

Behavioural and General Developmental Screening Tools

The tools in this section allow paediatricians and other child health care providers to incorporate developmental surveillance and screening into regular health care visits. They can facilitate anticipatory guidance to families about supporting their child’s development. They measure general behaviour and development and provide information on functioning in multiple domains, which can alert a health care professional to a potential mental health condition.

Condition-specific Screening Tools and Rating Scales

These screening tools help with diagnosis. A careful history of the symptoms and their impact on functioning must be included in any diagnostic assessment.
