EASI Praxis Tests: Age Trends and Internal Consistency.

Area of Science:

• Neuroscience
• Developmental Psychology
• Occupational Therapy

Background:

• Ayres Sensory Integration® is an evidence-based practice requiring thorough assessment.
• The Evaluation in Ayres Sensory Integration (EASI) is designed for assessment, necessitating psychometric validation.
• Previous research highlighted the need for psychometric data on EASI's validity and reliability.

Purpose of the Study:

• To evaluate the internal consistency of four EASI Praxis tests.
• To determine the validity of EASI Praxis tests as developmental measures.
• To assess the sensitivity of EASI Praxis tests to developmental changes in children and adolescents.

Main Methods:

• Cross-sectional developmental study design.
• Participants included 234 typically developing children and young adolescents aged 6 to 12 years.
• Analysis involved Cronbach's α, Pearson correlation coefficients, and one-way ANOVA for internal consistency and developmental trends.

Main Results:

• All four EASI Praxis tests demonstrated moderate to high internal consistency.
• Significant correlations between age and praxis scores confirmed the tests' sensitivity to developmental changes.
• Praxis ability showed continued development into early adolescence.

Conclusions:

• Occupational therapists can rely on the internal consistency and developmental sensitivity of EASI Praxis scores for ages 6 to 12.
• The findings support the continued development of praxis into early adolescence.
• EASI Praxis tests can inform assessment and intervention for praxis ability in this age group.
