To carry out our research program over the years, my students, colleagues, and I have developed a number of questionnaires used not only by ourselves but also by other researchers. These are freely available to any researcher who wants to use them but may not be reproduced for sale. Titles link to a copy of the associated questionnaire.

Affective Control Scale

This measure is intended to measure apprehension about losing control in the face of strong emotions. Instructions for scoring are included here.

Agoraphobic Cognitions Questionnaire and Body Sensations Questionnaire

These companion measures assess two aspects of what we have dubbed the fear of fear in patients with panic disorder and agoraphobia – catastrophic thinking about anxiety and panic and fear of the bodily sensations associated with anxiety and panic. ACQ BSQ Instructions.

Attributions of Criticism Scale

This measure is designed to tap the positive and negative attributions individuals make about criticism from the most important people in their lives. This measure has proved predictive of ratings of perceived constructive and destructive criticism in longitudinal and cross-sectional research.

Mobility Inventory

This questionnaire is designed to assess self-reported avoidance of common situations feared by people with agoraphobia. There are separate scales for avoidance when alone and when accompanied by a trusted companion. The original version of this measure had separate scales for discomfort, but these proved to be so highly correlated with avoidance that we dropped them. Mobility Inventory Instructions.

Parental Facilitation of Mastery Scale

This measure is designed to obtain participants’ retrospective reports of their parents’ behavior toward them in the first 16 years of life with the goal of identifying behaviors that are associated with mastery/self-efficacy and lower anxiety in adult life. This two-factor scale assesses not only overprotection but also whether parents actively challenged the child to master difficulties. The validation of the current version of the scale, PFMS-II, is described by Zalta et al. (in press).
