“…In terms of similarities, both AP and PEP are processes that are considered repetitive, negatively valenced, centered on social performance, and difficult to disengage from (Laposa & Rector, 2016). Conversely, there also appears to be functional differences between them that support their diagnostic specificity (for a review of AP, see Sluis, Boschen, Neumann, & Murphy, 2017a; for a review of PEP, see Brozovich & Heimberg, 2008; Sluis, Boschen, Neumann, & Murphy, 2017b; Wong, 2016). The most distinct differences between AP and PEP include temporal orientation (i.e., prior to an event and post-event) and discrepancy (i.e., a completed vs. an uncompleted task; Martin & Tesser, 1996).…”
