To work towards a scalable, low\u2010cost intervention for improving ER, we developed a novel contextual recommender algorithm for ER strategies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Design<\/jats:title>\n                    <jats:p>\n                      <jats:italic>N<\/jats:italic>\n                      \u2009=\u2009114 socially anxious participants were prompted via a mobile app up to six times daily for five weeks to report their emotional state, use of 19 different ER strategies (or no strategy), physical location, and social context.

For each approach, an algorithm that recommends strategies based on one\u2019s current context was compared with an algorithm that recommends ER strategies randomly, an algorithm that always recommends cognitive reappraisal, and the person\u2019s observed ER strategy use. Contextual bandits were used to predict the effectiveness of the strategies recommended by each policy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>When strategies were grouped into categories, the contextual algorithm was not the best performing policy. However, when the top ten strategies were considered individually, the contextual algorithm outperformed all other policies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Grouping strategies into categories may obscure differences in their contextual effectiveness. Further, using strategies tailored to context is more effective than using cognitive reappraisal indiscriminately across all contexts. Future directions include deploying the contextual recommender algorithm as part of a just\u2010in\u2010time intervention to assess real\u2010world efficacy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Practitioner points<\/jats:title>\n                    <jats:p>\n                      <jats:list list-type=\"bullet\">\n                        <jats:list-item>\n                          <jats:p>Emotion regulation strategies vary in their effectiveness across different contexts.<\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>An algorithm that recommends emotion regulation strategies based on a person\u2019s current context may one day be used as an adjunct to treatment to help dysregulated individuals optimize their in\u2010the\u2010moment emotion regulation.<\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>Recommending flexible use of emotion regulation strategies across different contexts may be more effective than recommending cognitive reappraisal indiscriminately across all contexts.<\/jats:p>\n                        <\/jats:list-item>\n                      <\/jats:list>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/bjc.12282","type":"journal-article","created":{"date-parts":[[2021,2,14]],"date-time":"2021-02-14T12:51:48Z","timestamp":1613307108000},"page":"51-72","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Building an emotion regulation recommender algorithm for socially anxious individuals using contextual bandits"],"prefix":"10.1111","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0846-9682","authenticated-orcid":false,"given":"Miranda L.","family":"Beltzer","sequence":"first","affiliation":[{"name":"Department of Psychology University of Virginia Charlottesville Virginia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1398-1269","authenticated-orcid":false,"given":"Mawulolo K.","family":"Ameko","sequence":"additional","affiliation":[{"name":"Department of Engineering Systems and Environment University of Virginia Charlottesville Virginia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4371-2740","authenticated-orcid":false,"given":"Katharine E.","family":"Daniel","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Virginia Charlottesville Virginia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9438-4524","authenticated-orcid":false,"given":"Alexander R.","family":"Daros","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Virginia Charlottesville Virginia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6295-2523","authenticated-orcid":false,"given":"Mehdi","family":"Boukhechba","sequence":"additional","affiliation":[{"name":"Department of Engineering Systems and Environment University of Virginia Charlottesville Virginia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura E.","family":"Barnes","sequence":"additional","affiliation":[{"name":"Department of Engineering Systems and Environment University of Virginia Charlottesville Virginia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9031-9343","authenticated-orcid":false,"given":"Bethany A.","family":"Teachman","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Virginia Charlottesville Virginia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,2,14]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/1745691612459518"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.brat.2010.06.002"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.brat.2012.04.004"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1080\/02699931.2012.739998"},{"key":"e_1_2_7_6_1","doi-asserted-by":"crossref","unstructured":"Ameko M.
