Several reports indicated that people in distress were turning to digital technology, but there was little evidence about the impact of these tools on mitigating distress.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>This study seeks to determine the acceptability, feasibility, usability, and effectiveness of mobile mental health apps for decreasing mental health symptoms in essential workers and unemployed individuals with suicide risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We recruited participants who indicated that they were unemployed because of COVID-19 or were COVID-19\u2013designated essential workers. Participants were randomized to 1 of 4 free commercial mobile apps for managing distress that were (1) highly rated by PsyberGuide and (2) met the criteria for intervention features these participants indicated were desirable in a previous survey. Participants used the apps for 4 weeks and completed baseline and 4-week self-assessments of depression, anxiety emotional regulation, and suicide risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We found no differences between the apps in any outcome but did find significant changes in depression and anxiety over time (Patient Health Questionnaire [PHQ]-9: estimate=\u20131.5, SE 0.2, 95% CI \u20131.1 to \u20131.8, P&lt;.001; Generalized Anxiety Disorder Scale [GAD]-7: estimate=\u20131.3, SE 0.2, 95% CI \u20131.0 to \u20131.6, P&lt;.001). We found no significant changes in suicidal behavior (Suicide Behaviors Questionnaire-Revised [SBQ-R]) or emotional regulation (Difficulties in Emotion Regulation Scale \u2013 Short Form [DERS-SF]) for the 4 weeks. We did find a significant dose-response pattern for changes in depression and anxiety. Using the app at least once a week resulted in greater improvements in treatment conditions over time on depression (estimate=\u20130.6, SE 0.2, 95% CI 1.0-0.2, P=.003) and anxiety (estimate=0.1, SE 0.2, 95% CI 0.4-0.6, P=.78). There was no association between app frequency and changes in suicidal behavior (SBQ-R) or emotional regulation (DERS-SF). We further found a significant difference between the conditions with regard to app usability, with the control app being the most usable (meanBeautiful Mood 72.9, SD 16.7; meanCOVID Coach 71.2, SD 15.4; meanCalm 66.8, SD 17.3; mean7 Cups 65.2, SD 17.7).

This study found that free, self-guided commercial mobile mental health apps are seen as usable, but no one app is superior to the other. Although we found that regular use is indicated for effects on depression and anxiety to occur in those who are more symptomatic, regression to the mean cannot be ruled out.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Trial Registration<\/jats:title>\n                    <jats:p>ClinicalTrials.gov NCT04536935; https:\/\/tinyurl.com\/mr36zx3s<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2196\/41689","type":"journal-article","created":{"date-parts":[[2022,9,30]],"date-time":"2022-09-30T17:56:56Z","timestamp":1664560616000},"page":"e41689","source":"Crossref","is-referenced-by-count":32,"title":["Effectiveness of Mental Health Apps for Distress During COVID-19 in US Unemployed and Essential Workers: Remote Pragmatic Randomized Clinical Trial"],"prefix":"10.2196","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0398-4108","authenticated-orcid":false,"given":"Katherine Anne","family":"Comtois","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6218-2917","authenticated-orcid":false,"given":"Felicia","family":"Mata-Greve","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2081-6176","authenticated-orcid":false,"given":"Morgan","family":"Johnson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8404-864X","authenticated-orcid":false,"given":"Michael D","family":"Pullmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0670-3412","authenticated-orcid":false,"given":"Brittany","family":"Mosser","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5971-6319","authenticated-orcid":false,"given":"Patricia","family":"Arean","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2022,11,7]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph182111315"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1111\/anae.15408"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1089\/hs.2021.0017"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.2196\/28360"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jagp.2021.03.005"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.2196\/27619"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.2196\/27404"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.47176\/mjiri.34.85"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1037\/bul0000334"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.2196\/jmir.7740"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.2196\/14567"},{"key":"ref12","unstructured":"One Mind PsyberGuide2022-08-03https:\/\/onemindpsyberguide.org\/"},{"key":"ref13","unstructured":"American Psychiatric AssociationApp Advisor: An American Psychiatric Association Initiative2022-08-03https:\/\/www.psychiatry.org\/psychiatrists\/practice\/mental-health-apps"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1176\/appi.ps.202000561"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1002\/wps.20592"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1093\/cid\/ciaa1311"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.2196\/jmir.6482"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1145\/3178876.3186062"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1145\/2750858.2804250"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbef.2017.12.004"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1016\/j.jesp.2017.01.006"},{"key":"ref22","unstructured":"ProlificA Higher Standard of Online Research2022-10-05https:\/\/www.prolific.co\/"},{"key":"ref23","unstructured":"LettmannHLumsdenJProlific\u2019s Participant Pool -
