Disruptions in circadian rhythm, such as 24\u2010h rest\u2010activity patterns, are a relevant risk factor for SI, yet understudied in BD youth. The present cross\u2010sectional study examined the associations between actigraphy\u2010derived rest\u2010activity rhythms (RARs) and self\u2010reported suicidal ideation (SI) severity in a sample of 54 BD youth (aged 12\u201318\u2009years).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>\n                      Participants completed daily wrist actigraphy (M\n                      <jats:sub>days<\/jats:sub>\n                      \u2009=\u200918.89, range: 6 to 29\u2009days) and non\u2010parametric RAR measures were derived for analyses. At the same time, participants provided self\u2010report data on depressive symptoms and SI severity (number of days between actigraphy start and questionnaire completion: M\n                      <jats:sub>days<\/jats:sub>\n                      \u2009=\u2009\u22127.74, SD\u2009=\u200913.33, range: \u221246 to 28\u2009days).
