Concurrent Validity

Concurrent validity refers to how well a new measure of a construct compares with an already established and accepted measure of the same construct, when measured at the same time.

Predictive Validity

Predictive validity refers to how well a measure can predict future outcomes or events.

Content Validity

Content validity refers to how well the content of a measure accurately reflects the concept it is intended to measure.

Convergent Validity

Convergent validity is demonstrated when two different measures of the same construct show a strong correlation, meaning they are measuring essentially the same thing.

Divergent Validity

Divergent validity, also known as discriminant validity, is demonstrated when two measures of different constructs show a weak or no correlation, meaning they are measuring different things.

Validity in research

The extent to which a measurement procedure accurately measures the variable it claims to measure.

Face Validity

An assessment of whether a measure appears to measure what it claims to measure. A measure with high face validity seems logical and relevant to the concept being measured.

Reliability vs. Validity

Reliability is a necessary but not sufficient condition for validity. Even if a measure is reliable, it may not be valid.

Key takeaway: Validity and Reliability

A measurement procedure is considered valid if it measures what it intends to measure. It is reliable if it produces consistent results.

Study Notes

Validity in Measurement

  • Validity assesses if a measurement procedure accurately measures the intended variable.
  • It's crucial for indirectly observed variables, where the relationship between a measure and the concept being measured might be complex.
  • Validity isn't inherent to a measure; it's evaluated based on different types.

Types of Validity

  • Face validity: A measure appears to measure the intended construct. This is a basic requirement but can be subjective.

    • Example: Items on the DASS-21 ("I found it hard to wind down") have high face validity for measuring stress.

  • Concurrent validity: A measure compares well with a known criterion (another established measure) at the same time.

    • Example: A new depression measure is compared with a well-established scale like the HDRS. Consistency suggests both measures are valid.

  • Predictive validity: A measure accurately predicts future events.

    • Example: A pretrial risk assessment predicts future criminal behavior by evaluating court attendance and new offences.

  • Content validity: A measure comprehensively covers the construct's components.

    • Example: To measure intelligence, a measure should assess various aspects like reasoning and problem-solving, as outlined in Gottfredson's definition.

  • Convergent validity: Strong relationship between two measures of the same construct.

    • Example: The BDI-II and RADS both measure adolescent depression, showing a strong overlap in their scores.

  • Divergent validity (discriminant validity): Little or no relationship between measures of different constructs.

    • Example: Low correlation between depression and social anxiety scores, supporting that they are distinct constructs.
