“…Escalation can be defined as a qualitative and/or quantitative increase in stalking, harassing, or threatening behaviors and may include frequency of harsher language, graphic or threatening enclosures, closer modes of delivery, more modes of delivery, ancillary incidents, and increased personalization indicators (Borum et al, 1999; Burgess et al, 1997; McEwan et al, 2012; Meloy et al, 2012; Rugala & Fitzgerald, 2003). Escalation has been associated with violence (Burgess et al, 1997; Kropp, 2008; Kropp et al, 2002; Rugala & Fitzgerald, 2003; Sato Mumm & Cupach, 2010; Sheridan et al, 2001). Higher intensity and/or greater frequency of stalking have also been associated with greater psychological distress (Blaauw et al, 2002; Botuck et al, 2009; Kamphuis et al, 2003; Mechanic, Uhlmansiek, Weaver, & Resick, 2000; Mechanic, Weaver, et al, 2000).…”
