The convergent validity showed good correlation coefficient of the Prenatal Self-Assessment Questionnaire with the Experience in Close Relationships Questionnaire ranging from 0.32 and 0.459. In addition, the high correlation of the subscales with the total score confirmed the construct validity of the questionnaire. The content validity of the questionnaire was confirmed by 5 experts.
