To test the psychometric properties of the Subjective Units of Disturbance Scale (SUDS), this study analyzed the data from 61 patients treated with EMDR. The pretreatment self-reported questionnaires, the in-session records of EMDR, and the Clinical Global Impression–Change (CGI-C) scale at the termination of EMDR were reviewed. The initial score of the SUDS at the first session was significantly correlated with the patient's level of depression, the state anxiety, and distress from the impact of events. The final score of the SUDS at the first session was significantly correlated with the CGI-C score at termination. Consequently, this study confirmed that the SUDS in EMDR sessions has good psychometric properties.
