Testing and validating the trait emotional intelligence questionnaire
Clearly it is relatively easy to label a scale ‘Leadership’ or ‘Honesty’ but it is quite another matter to demonstrate whether it really works.
Content Validity (also known as logical validity) refers to the extent to which a measure represents all facets of the construct (e.g. For example, a depression scale may lack content validity if it only assesses the affective dimension of depression but fails to take into account the behavioural dimension.
Types of Validity Face Validity is concerned with whether a selection instrument appears to measure what it was designed to measure.
Such constructs might be mechanical, verbal or spatial ability, emotional stability or intelligence.
Correlations with other scales will provide useful information on a test’s construct validity (we would expect a scale of dominance to be more highly related to other measures of dominance than to traits of anxiety).
Whilst face validity has no technical or statistical basis, it must not be overlooked if a test is to be accepted by the respondent.
In a personality questionnaire, the question of face validity often relates to the questions asked.
