Firefighters, critical incidents, and drinking to cope: the adequacy of unit-level performance resources as a source of vulnerability and protection

The authors investigated the moderating role of unit-level performance resources on the distress-mediated relationship between the intensity of involvement in workplace critical incidents and problematic drinking behavior (i.e., drinking to cope). Building on recent developments in hierarchical linear modeling, the authors tested a cross-level, moderated-mediation model using data from 1,481 firefighters in 144 companies. The findings indicate that (a) there is a significant, distress-mediated association between intensity of involvement in such incidents and drinking to cope, which varies by company (i.e., unit), and (b) the adequacy of unit-level performance resources explains much of this cross-unit variance and attenuates both individual-level mediation stages (i.e., intensity of involvement in critical incidents 3 distress, and distress 3 drinking to cope). Implications regarding the role of unit resources adequacy as a vulnerability factor in stressor-strain relations are discussed.
