As a result, standardized digital tools are needed to measure mood. We sought to validate a new survey that is brief, validated in digital form, and able to separately measure manic and depressive severity.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We introduce a 6\u2010item digital survey, called digiBP, for measuring mood in BP. It has three depressive items (depressed mood, fidgeting, fatigue), two manic items (increased energy, rapid speech), and one mixed item (irritability); and recovers two scores (<jats:italic>m<\/jats:italic> and <jats:italic>d<\/jats:italic>) to measure manic and depressive severity. In a secondary analysis of individuals with BP who monitored their symptoms over 6\u00a0weeks (<jats:italic>n<\/jats:italic>\u00a0=\u00a043), we perform a series of analyses to validate the digiBP survey internally, externally, and as a longitudinal measure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We first verify a conceptual model for the survey in which items load onto two factors (\u201cmanic\u201d and \u201cdepressive\u201d). We then show weekly averages of <jats:italic>m<\/jats:italic> and <jats:italic>d<\/jats:italic> scores from digiBP can explain significant variation in weekly scores from the Young Mania Rating Scale (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup>\u00a0=\u00a00.47) and SIGH\u2010D (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup>\u00a0=\u00a00.58). Lastly, we examine the utility of the survey as a longitudinal measure by predicting an individual\u2019s future <jats:italic>m<\/jats:italic> and <jats:italic>d<\/jats:italic> scores from their past <jats:italic>m<\/jats:italic> and <jats:italic>d<\/jats:italic> scores.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>While further validation is warranted in larger, diverse populations, these validation analyses should encourage researchers to consider digiBP for their next digital study of BP.<\/jats:p><\/jats:sec>","DOI":"10.1111\/bdi.13058","type":"journal-article","created":{"date-parts":[[2021,2,15]],"date-time":"2021-02-15T19:20:08Z","timestamp":1613416808000},"page":"810-820","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["A digital self\u2010report survey of mood for bipolar disorder"],"prefix":"10.1111","volume":"23","author":[{"given":"Tijana","family":"Sagorac Gruichich","sequence":"first","affiliation":[{"name":"University of Wisconsin Madison WI USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan Camilo","family":"David Gomez","sequence":"additional","affiliation":[{"name":"University of Wisconsin Madison WI USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriel","family":"Zayas\u2010Cab\u00e1n","sequence":"additional","affiliation":[{"name":"University of Wisconsin Madison WI USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0375-6247","authenticated-orcid":false,"given":"Melvin G.","family":"McInnis","sequence":"additional","affiliation":[{"name":"University of Michigan Ann Arbor MI USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6024-796X","authenticated-orcid":false,"given":"Amy L.","family":"Cochran","sequence":"additional","affiliation":[{"name":"University of Wisconsin Madison WI USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,2,26]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jad.2017.12.059"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen\u20102013\u2010003353"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/0004867418808900"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291719000710"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/wps.20673"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1399\u20105618.2012.00998.x"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1162\/cpsy_a_00021"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41398\u2010017\u20100084\u20104"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/bdi.12246"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jad.2019.09.076"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40345\u2010017\u20100116\u20102"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.2196\/11029"},{"key":"e_1_2_8_14_1","doi-asserted-by":"crossref","unstructured":"MattonK McInnisMG ProvostEM.Into the wild: transitioning from recognizing mood in clinical interactions to personal conversations for individuals with bipolar disorder.
