“…Nevertheless, significant sleep-BPD associations were also found in community (Oltmanns et al, 2014;Selby, 2013) and prison (Harty et al, 2010) Fifth, some studies concentrated on the effects of comorbid or past history of depression (Akiskal, Yerevanian, Davis, King, & Lemmi, 1985), or just controlled for depression symptoms (Oltmanns et al, 2014), rather than a full range of psychiatric disorders. Bipolar disorder and post-traumatic stress disorder, for example, have been associated with both BPD (Zimmerman & Mattia, 1999) and sleep disturbance (Kobayashi, Boarts, & Delahanty, 2007;Plante & Winkelman, 2008). Nevertheless, the majority of studies did exclude participants with other psychiatric disorders (e.g., psychotic disorder, bipolar disorder, substance abuse, PTSD) or controlled for other psychiatric symptoms, e.g., substance abuse, PTSD (Harty et al, 2010;Selby et al, 2013), adding support to the independence of observed associations between BPD and sleep disturbance.…”
