Participation and Environment Measure
Also known as: PEM-CY, Participation and Environment Measure for Children and Youth, Children's Participation and Environment Measure, PEM Child Participation Measure
The Participation and Environment Measure for Children and Youth (PEM-CY) is a caregiver-report instrument that measures how children aged 5 to 17, with and without disabilities, participate in the home, school, and community, and the environmental supports and barriers that shape that participation. Developed by Wendy Coster, Mary Law, Gary Bedell, Mary Khetani and colleagues and published in 2011-2012, the PEM-CY operationalizes the participation construct of the World Health Organization's International Classification of Functioning, Disability and Health (ICF) by asking, for each setting, how often a child takes part, how involved they are, and whether the family desires change, alongside ratings of which environmental features help or hinder. Its distinctive contribution is to measure participation and environment together rather than treating the environment as a separate afterthought.
Key highlights
- Measures participation and the environment jointly, operationalizing the ICF view that participation is shaped by context rather than impairment alone.
- Captures three complementary participation dimensions — frequency, involvement, and desire for change — giving a richer profile than frequency counts.
- Reports setting-specific scores for home, school, and community, directing intervention to the contexts where barriers concentrate.
- Has established test-retest reliability and discriminates children with disabilities from typically developing peers, supporting group comparison and outcome tracking.

When to use it
Use the PEM-CY when you want to measure a child's real-world participation across home, school, and community together with the environmental supports and barriers shaping it, rather than measuring body function or clinic-based capacity. It is well suited to disability and rehabilitation research, program evaluation, and intervention planning where the goal is to improve participation and where the environment is a plausible lever. It depends on a knowledgeable caregiver respondent and is designed for children aged roughly 5 to 17. It is less appropriate when you need a direct performance assessment, when the relevant outcome is a discrete clinical capacity, or when no caregiver who observes the child across settings is available; in those cases pair it with capacity or self-report measures.
Strengths & limitations
- Measures participation and the environment jointly, operationalizing the ICF view that participation is shaped by context rather than impairment alone.
- Captures three complementary participation dimensions — frequency, involvement, and desire for change — giving a richer profile than frequency counts.
- Reports setting-specific scores for home, school, and community, directing intervention to the contexts where barriers concentrate.
- Has established test-retest reliability and discriminates children with disabilities from typically developing peers, supporting group comparison and outcome tracking.
- Relies on caregiver report, so it reflects a proxy's perception and may diverge from the child's own experience, especially for older youth.
- The environmental section records perceived supports and barriers, which are subjective and may not correspond to objective environmental audits.
- Aggregated setting scores can mask item-level detail, and the desire-for-change rating mixes the child's and family's preferences.
- Norms and validity evidence derive largely from North American samples, so cross-cultural use requires adaptation and revalidation.

Frequently asked
How is the PEM-CY different from other participation measures?
Most participation measures count how often a child does activities; the PEM-CY measures frequency, involvement, and desire for change and, crucially, pairs each setting with an environmental section rating supports, barriers, and resource availability. This joint measurement reflects the ICF principle that participation is produced by the interaction of the child and the environment, so a low score can be interpreted in context rather than read as an individual deficit. Coster and colleagues built the content from both the ICF-CY framework and parents' own perspectives.
Who completes the PEM-CY and for which ages?
The PEM-CY is a caregiver-report measure for children and youth aged about 5 to 17, completed by a parent or guardian who observes the child across home, school, and community. Because it is proxy-report, it captures the caregiver's perception of participation and environment, which is valuable for planning but should be complemented by the child's own voice where possible. For younger children, a companion instrument, the Young Children's Participation and Environment Measure, covers ages 0 to 5.
What does the environment section add?
The environment section asks, within each setting, whether specific features help or hinder participation and whether needed resources are available. This is the PEM-CY's signature feature: it lets the analyst attribute restricted participation partly to an unsupportive environment and identify which barriers are most amenable to change. Without it, participation scores risk being read as fixed properties of the child, which contradicts the social and ICF models of disability that motivated the instrument.
