In “Mobile Insight in Risk, Resilience, and Online Referral (MIRROR): Psychometric Evaluation of an Online Self-Help Test” (J Med Internet Res 2020;22(9):e19716) one correction was made. This does not affect the analysis nor does it affect the interpretation or presentation of the results in the study.

In the “Methods” section, under “Measures” and “Depression, Anxiety and Stress”, the following phrase appears:

Grief disorders have recently been included in international diagnostic classifications, including the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders [DSM-5; (1)] and the 11th edition of the International Classification of Diseases [ICD-11; (2)]. Specifically, DSM-5 now includes the category “other specified trauma- and stressor-related disorder,” with persistent complex bereavement disorder as one of the specific examples, and ICD-11 includes prolonged grief disorder (PGD).

Background: The coronavirus pandemic appears to put psychiatric patients with pre-existing symptomatology at risk of symptom increase, but evidence is scarce. While the pandemic and stringent governmental measures have accelerated the use of clinical videoconferencing (VCT), patient satisfaction with VCT is unclear. 

Objective: Aim of the study was to assess the wellbeing of patients in psychotrauma treatment during the coronavirus pandemic and to evaluate their use of and satisfaction with VCT. 

Emotionally arousing experiences are retained very well as seen in posttraumatic stress disorder (PTSD). Various lines of evidence indicate that reactivation of these memories renders them labile which offers a potential time-window for intervention. We tested in non-human primates whether ketamine, administered during fear memory reactivation, affected passive (inhibitory) avoidance learning. For the consolidation of contextual emotional memory, the unescapable foot-shock paradigm in a passive avoidance task with two compartments (dark vs illuminated) was used.
