Abstract

Moral distress (Md) is the psychological disequilibrium experienced when one perceives the right moral action to take but is constrained from taking that action. Only one study has focused specifically on Md among respiratory therapists (RTs). Research demonstrates a correlation between Md and perception of workplace ethical climate (PEC). It is important to study this problem in all health care workers (HCWs) because, left unaddressed, Md may result in adverse emotional and physical symptoms, increased risk of burnout, and loss of HCWs from the workforce. Existing surveys may underestimate Md in non-nursing HCWs.

Five RT-specific survey items were designed for and administered to RTs along with a validated Md instrument (MDS-R) that has been utilized in nursing research. Survey reliability was assessed with calculation of Cronbach's alpha. Statistical analyses were performed on 1) moral distress index (MdI) measured with and without RT-specific survey items; 2) MdI in RTs who had left or considered leaving a clinical position because of Md versus RTs who had not done so; and 3) the relationship between Md and the PEC.

Cronbach's alpha was 0.898. Two of the five RT-specific Md survey items demonstrated construct validity with two recent studies in RTs. The MdI measured using the revised survey was significantly higher than that from the MDS-R alone (r = .982, p < 0.001). The MdI was significantly higher in RTs who had ever left or considered leaving a position because of their Md than in those who had never done so (p < .021); and among those currently planning versus not planning leave a position (p < 0.001). There was a negative correlation (-0.423) between Md and PEC.

The data supported the hypothesis that augmenting a generic survey with a limited number of discipline-specific items optimized Md assessment in RTs. Correlations reported elsewhere of job attrition and PEC with Md are replicated in this study.

Validation of new survey items should continue. Other HC disciplines are encouraged to develop discipline-specific Md survey items for their constituencies. End-of-life education for RTs and their colleagues is recommended.
