Details of the methods have been reported previously [4]. Briefly, recruitment for this cross-sectional study (April 24, 2020 – May 12, 2020) was performed via email distribution (sent out three times) to known Detroit area HCWs and subsequent snowball sampling using Qualtrics platform. Current HCWs in area hospital were eligible. Participants were given information about the study and were asked to complete an anonymous, online survey which included the standardized mental health scales. Completion of the survey implied informed consent. For this analysis we examined HCWs with previous psychiatric diagnosis, demographics, and sources of stressors. Importantly, we asked the HCW with previous psychiatric diagnosis, “Do you feel the current COVID-19 crisis has worsened your psychiatric symptoms?” to see if it had impacted their mental health “not at all”, “a little bit”, “a moderate amount”, or “a great deal”.
The standardized mental health scales were the Perceived Stress Scale (PSS), Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-8 (PHQ-8), and Posttraumatic Stress Disorder Checklist (PCL) [7, 10,11,12]. The PSS is the most widely used psychological instrument for measuring perceived stress and has high convergent validity with scales that measure anxiety and depression, as well as inferring clinical consequences [7, 13]. The PSS score ranges from 0 to 40, with scores from 0 to 13 (low), 14–26 (moderate), and 27–40 (severe) perceived stress [7]. The GAD-7 is a valid brief self-report scale for measuring the severity of anxiety, mainly in outpatients [11]. The GAD-7 total score for the seven items ranges from 0 to 21, with 0–4: minimal anxiety, 5–9: mild anxiety, 10–14: moderate anxiety, and 15–21: severe anxiety [11]. The PHQ-8 is a widely used psychological tool with high reliability and validity that measures depressive symptoms [10]. The PHQ-8 total score ranges from 0 to 4: minimal depression, 5–9: mild depression, 10–14: moderate depression, 15–19: moderately severe depression, and 20–24: severe depression [10]. The PCL-5 is a widely used self-report measure of posttraumatic stress symptoms that can be used in a variety of contexts to screen for PTSD symptoms and monitor symptom change during and after treatment [12].
Individual questions were also developed by the researchers. They included self-reported adequacy of personal protective equipment (PPE), resources for patients and training for highly contagious diseases for HCWs. These questions were rated on 7-point Likert scale with anchors of 1 = extremely inadequate and 7 = extremely adequate. Individual sources of stress were rated on a 7-point Likert scale with labels of 1 = Not at all stressful, 4 = somewhat stressful and 7 = extremely stressful. These sources of stress included risk of transmitting to family member, friend, and/or member of household, contracting disease, avoiding physical contact with others, finances, not spending time with family/friends, and tension at work.
One open-ended question was included at the end of the survey that stated, “Please include any additional comments regarding your experience with COVID-19 and mental health”.
