The Impact of Individual Variables on perceived effort-reward imbalance and fatigue need for recovery in industrial firefighters

Firefighting is a stressful job with great degree of physical and psychological demands. The effort-reward imbalance and fatigue need for recovery in this occupational group can lead to the serious consequences. The present study tries to assess the influences of the personal variables on the effort-reward imbalance and fatigue need for recovery.   In this cross sectional study, 107 industrial firefighter were recruited in 2018. The effort-reward imbalance and fatigue need for recovery questionnaire were used to collect the required information. The data analyzed by multiple linear regression with SPSS 16 and statistical significance level was less than 0.05. More than 70 percent of the population study reported a desirable level of effort-reward imbalance and fatigue need for recovery status. The results of regression analysis revealed a meaningful relation among personal variables and contractual status with need for recovery index. In addition, a meaningful relation was found between the type of contractual status, sleep disorders and hypnotic drug with over-commitment. However, there was no meaningful relation for effort-reward imbalance.  The results showed a relative desirable status for effort-reward imbalance and need for recovery in the study group. It is recommended to intervene in working condition to obtaining more precise results.
