The Depressive Experiences Questionnaire (DEQ; Blatt, Quinlan, & D'Afflitti, 1976) and the Depressive Experiences Questionnaire for adolescents (DEQ-A; Blatt, Schaffer, Bers, & Quinlan, 1992) are both copyrighted.  However, the authors are happy to have them used by qualified researchers and clinicians without cost.  They have given me permission to distribute the scales by email.  For additional information, contact Prof. Sidney Blatt ( at Yale University.

   Several shortened versions of the DEQ have been published, including one from our lab (Santor, Zuroff, & Fielding, 1997.  Unless brevity is crucial to you, I recommend that you use the standard, 66-item version of  the DEQ.  An important advantage of the standard DEQ is that there are scoring procedures for extracting subscales of the Dependency or interpersonal factor.  The subscales represent more and less mature forms of interpersonal relatedness.  For additional information about these subscales, see the following references:
