What does content validity evaluate?

Content validity evaluates the extent to which a test comprehensively covers the intended area of assessment. This means that the test items should reflect a representative sampling of the subject or construct being measured. For example, in therapeutic recreation, if a test is designed to assess knowledge of leisure skills, content validity would ensure that the questions encompass a wide range of leisure activities, skills, and relevant theories related to the field. This ensures that the test is measuring what it is supposed to measure and is thus a valid tool for evaluation purposes.

The focus on areas such as coverage helps assess whether important aspects are included, which dramatically impacts the usefulness of the test for making informed decisions or evaluations. This is crucial in fields like therapeutic recreation, where understanding the breadth of knowledge and skills is vital for effective practice and client care.
