Background: In eye movement desensitization and reprocessing (EMDR), patients make eye movements (EM) while recalling traumatic memories. Making EM taxes working memory (WM), which leaves less resources available for imagery of the memory. This reduces memory vividness and emotionality during future recalls. WM theory predicts that individuals with small working memory capacities (WMCs) benefit more from low levels of taxing (i.e., slow EM) whereas individuals with large WMC benefit more from high levels of taxing (i.e., fast EM).

Background
Suicidal ideation (SI) is common in chronic depression, but only limited evidence exists for the assumption that psychological treatments for depression are effective for reducing SI.

This Special Communication argues for changing the definition of posttraumatic stress disorder in DSM-5. Are changes to the definition of posttraumatic stress disorder in DSM-5 a step forward?—Yes.

We take strong exception to many of the assertions, conclusions, and recommendations in the article by Hoge et al1 in this issue of JAMA Psychiatry. Although Hoge et al1 identify a number of reasons they do not support the DSM-52 workgroup’s revisions to the diagnosis of posttraumatic stress disorder (PTSD), we believe that their basic arguments are that

Animals have a long history of inclusion in psychiatric treatment. There has been a recent growth in the empirical study of this practice, known as Animal-Assisted Intervention (AAI). We conducted a systematic review of the empirical literature on AAI for trauma, including posttraumatic stress disorder (PTSD). Ten studies qualified for inclusion, including six peer-reviewed journal articles and four unpublished theses. Participants were predominantly survivors of child abuse, in addition to military veterans. The presentation of AAI was highly variable across the studies.
