Content validity
Explanation:
Content validity refers to the fact that a study actually measures all aspects of the construct.
For a study to be valid, <u>the measurement method must cover all relevant parts of the subject it is measuring</u>. If it doesn't do so, then the validity of the study is treatment because of content validity.
In this case, the construct we are studying (quality of a relationship) has three parts (belong, interdependence and intimacy). Since <u>the questionnaire doesn't include items tapping intimacy it is not covering all three parts of the construct</u> and therefore it is lacking content validity.
