Achievement of Therapeutic Objectives Scale (ATOS)

The ATOS started as a research instrument based on the therapeutic objectives of Defense Restructuring, Affect Restructuring and Self/Other Restructuring. Rating sessions with ATOS can help therapists get even more benefit out of reviewing videotapes of their sessions. It can be a useful way of focusing on how well their therapy is moving toward its objectives. For more information, go to the Treating Affect Phobia Manual.

ATOS Therapist is an adaptation of Leigh McCullough’s ATOS. The difference between the two scales is that ATOS Therapist notes the minute to minute interactions of the therapist instead of the patient. The inspiration for creating the ATOS Therapist scale comes from a deep desire to understand what happens within the patient therapist relationship to create change. For therapist who film their psychotherapy sessions, the ATOS and ATOS Therapist are invaluable tools to objectively identify the actual moments where a patient(s) and therapist(s) experiences shifts in their level of anxiety, affect, or defenses and to rate them on a scale from 0-100. Therapist can use this information in multiple ways in order to improve the experience of psychotherapy for their patients. When we teach psychotherapist we strongly recommend that they film their psychotherapy sessions (with the written permission of their patients) and use the ATOS and ATOS Therapist in order to improve their psychotherapy and expand their understanding of what really creates change so our patients can feel better and lead more satisfying lives

The Affect Phobia Test

The Affect Phobia Test was developed by McCullough and co-workers simultaneously in English and Norwegian (McCullough, Berggraf, & Ulvenes, 2010) as a screening instrument to estimate fear of affects and the capacity for adaptive affective functioning. It was translated into Swedish in 2012. The instrument is structured to measure affect phobia in different affective domains. The first evaluation of the psychometric properties of the Affect Phobia Test, using the Swedish version (Frankl, Philips & Wennberg, submitted), show that the empirical cut-off for adaptive affective functioning should be set at >72 points and that the test should be considered as measuring the degree of adaptive affective functioning as a whole.

The Control Mastery Scale 

The Control Mastery Scale is an adaptation of previous work by Weiss and Sampson. Th Weiss Sampson framework identifies a Pathogenic Belief. Part A of the Control Mastery Scale asks coders to reach a consensus of the specific pathogenic belief. In Part B, coders rate the extent to which a therapist passes the test and helps the client disconfirm their pathogenic belief. It was created by James Donovan and Kristin Osborn.
