“…Symonds (1970) first drew this distinction in his model of the emotional hazards of police work that has guided much subsequent research and, in the UK policing context, resulted in the development of two parallel but disproportionate literatures. In the intervening decades numerous studies have explored UK police officers' exposure to operational stressors, especially exposure to traumatic critical incidents (e.g., Alexander and Wells, 1991;Brown and Fielding, 1993;Brown, Fielding, and Grover, 1999;Mitchell-Gibbs and Joseph, 1996), while fewer have focused on OPH exposures (e.g., Alexander, et al, 1993;Biggam et al, 1997;Brown and Campbell, 1990; Kirkcaldy, 1996, 1999;Brown and Fielding, 1993;Collins and Gibb, 2003;Cooper, Davidson, and Robinson, 1982;Kirkcaldy, et al, 1993).The relative paucity of research concerning UK police officers' OPH exposures is surprising given the UK-and officer-specific evidence to suggest that OPHs (a) are reported more often than operational psychosocial hazards -by a ratio of 4 to 1 (Brown and Campbell, 1990), (b) are perceived as more stressful than operational psychosocial hazards, and (c) may have an equal or even greater influence on UK police officers' health than exposure to 5 traumatic operational stressors (Biggam et al, 1997) and routine operational stressors (Alexander, et al, 1993; Collins and Gibbs, 2003). These findings do not appear to be peculiar to the UK; studies in Canada, New Zealand, the Netherlands, and the USA have produced similar results (Brough, 2004;Kop, Euwema, and Schaufeli, 1999;Shane, 2010;Taylor and Bennell, 2006).…”
