Different types of validity

What is meant by 'triangulation' in personality assessment?

Using multiple techniques or principles to measure personality, rather than relying on a single measure.

What does internal reliability refer to in the context of questionnaires?

It refers to the consistency of participants' responses, regardless of how the question is phrased.

What is Cronbach's alpha?

A statistic used to assess internal reliability, ranging from 0 to 1, where higher values indicate greater reliability, typically aiming for an alpha greater than 0.70.

What is inter-rater reliability?

It measures the consistency of assessments between different judges.

What does construct validity assess?

It assesses whether a measure accurately evaluates what it claims to evaluate.

Define face validity.

It is when a measure appears, at first glance, to evaluate what it claims to measure, though it is considered weak evidence of validity.

What is criterion validity?

It is the extent to which a measure correlates with relevant observable outcomes or behaviors.

What does convergent validity signify?

It signifies that a scale correlates with other self-report scales measuring similar constructs.

What is the definition of discriminant validity?

It indicates that a measure does not correlate highly with unrelated constructs, ensuring it measures only one thing.

What is content validity?

It refers to whether a measure covers all parts of a construct as defined by theory.
