However, only the visual analogue scales showed a significant difference between cases and controls over time. Such tests may prove valuable in furthering understanding about the evolution of manic mood states.<\/jats:p>","DOI":"10.1017\/s0033291706007835","type":"journal-article","created":{"date-parts":[[2006,5,17]],"date-time":"2006-05-17T10:44:49Z","timestamp":1147862689000},"page":"1213-1218","source":"Crossref","is-referenced-by-count":39,"title":["A pilot study of positive mood induction in euthymic bipolar subjects compared with healthy controls"],"prefix":"10.1017","volume":"36","author":[{"given":"ANNE","family":"FARMER","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"DOMINIC","family":"LAM","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"BARBARA","family":"SAHAKIAN","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JONATHON","family":"ROISER","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"AILBHE","family":"BURKE","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"NATHAN","family":"O'NEILL","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"SAM","family":"KEATING","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"GEORGIA POWELL","family":"SMITH","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"PETER","family":"McGUFFIN","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2006,5,17]]},"container-title":["Psychological Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0033291706007835","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,4,4]],"date-time":"2019-04-04T17:35:51Z","timestamp":1554399351000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0033291706007835\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2006,5,17]]},"references-count":0,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2006,9]]}},"alternative-id":["S0033291706007835"],"URL":"https:\/\/doi.org\/10.1017\/s0033291706007835","relation":{},"ISSN":["0033-2917","1469-8978"],"issn-type":[{"value":"0033-2917","type":"print"},{"value":"1469-8978","type":"electronic"}],"subject":[],"published":{"date-parts":[[2006,5,17]]}}}
