An expert to the content or professional that is familiar to the construct being measured is needed in this type of validity. The expert makes a judgment about the degree to which the items in the questionnaire COVER ALL RELEVANT PARTS of the construct it aims to measure.
Content Validity
Instrument Step 3. Types of Validity.
This type of validity measures how well the RELATIONSHIP between the result of your instrument to the result of another instrument. A criterion is an external measurement of the same thing. To evaluate this, the correlation between the result of your instrument and the result of the other instrument is computed.
Criterion Validity

Instrument Step 3. Types of Validity.
It defines how well a test measures what it claims to measure. It is used to know whether the operational definition of a construct aligns with the true theoretical meaning of a concept.
[If it can test something that cannot technically be measured directly such as depression.]
Construct Validity
nakabase dun sa construct na nageexist na like symptoms and other indicators since hindi nga direct yung measurement
