We explore this interaction with insomnia and nightmares independently of waking state arousal symptoms, and test predictions of the Interpersonal Theory of Suicide (<jats:styled-content style=\"fixed-case\">IPTS<\/jats:styled-content>) and Escape Theory in relation to these sleep arousal symptoms. Findings from our e\u2010survey (<jats:italic>n<\/jats:italic>\u00a0=\u00a0540) supported the <jats:styled-content style=\"fixed-case\">IPTS<\/jats:styled-content> over models of Suicide as Escape. Sleep\u2010specific measurements of arousal (insomnia and nightmares) showed no main effect, yet interacted with acquired capability to predict increased suicidality. The explained variance in suicidality by the interaction (1%\u20132%) using sleep\u2010specific measures was comparable to variance explained by interactions previously reported in the literature using measurements composed of a mix of waking and sleep state arousal symptoms. Similarly, when entrapment (inability to escape) was included in models, main effects of sleep symptoms arousal were not detected yet interacted with entrapment to predict suicidality. We discuss findings in relation to treatment options suggesting that sleep\u2010specific interventions be considered for the long\u2010term management of at\u2010risk individuals.<\/jats:p>","DOI":"10.1111\/sltb.12285","type":"journal-article","created":{"date-parts":[[2016,8,3]],"date-time":"2016-08-03T14:07:23Z","timestamp":1470233243000},"page":"370-381","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Investigating the Interaction Between Sleep Symptoms of Arousal and Acquired Capability in Predicting Suicidality"],"prefix":"10.1111","volume":"47","author":[{"given":"Kevin D.","family":"Hochard","sequence":"first","affiliation":[{"name":"Department of Psychology University of Chester Chester UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nadja","family":"Heym","sequence":"additional","affiliation":[{"name":"Department of Psychology Nottingham Trent University Nottingham UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ellen","family":"Townsend","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Nottingham Nottingham UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,8,2]]},"reference":[{"key":"e_1_2_6_2_1","volume-title":"Multiple regression: Testing and interpreting interactions","author":"Aiken L.
