Understanding psychological outcomes following exposure to potentially morally injurious events in animal care: development of the Moral Distress-Posttraumatic Growth Scale for Veterinary Professionals.

To generate a taxonomy of potentially morally injurious events (PMIE) encountered in veterinary care and develop an instrument to measure moral distress and posttraumatic growth following exposure to PMIE in the veterinary population. Development and preliminary evaluation of the Moral Distress-Posttraumatic Growth Scale for Veterinary Professionals (MD-PTG-VP) employed data from veterinary professionals (veterinarians, veterinary nurses, veterinary technicians) from Australia and New Zealand across three phases: (1) item generation, (2) content validation, and (3) construct validation. In Phase 1 respondents (n = 46) were asked whether they had experienced any of six PMIE and to identify any PMIE not listed that they had experienced. In Phase 2 a different group of respondents (n = 11) assessed a list of 10 PMIE for relevance, clarity and appropriateness. In Phase 3 the final instrument was tested with a third group of respondents (n = 104) who also completed the Short Post-Traumatic Stress Disorder Rating Interview (SPRINT), a measure of posttraumatic stress, and the Stress-Related Growth Scale–Short Form (SRGS-SF) a measure of perceived posttraumatic growth. Spearman's correlation coefficients were calculated between respondent scores on each of the MD-PTG-VP subscales, the SPRINT, and the SRGS-SF to assess construct validity. A 10-item taxonomy of PMIE encountered in veterinary care was generated in Phase 1. Items were deemed relevant, clear and appropriate by veterinary professionals in Phase 2. These were included in the developed instrument which measures frequency and impact of exposure to 10 PMIE, yielding three subscale scores (exposure frequency, moral distress, and posttraumatic growth). Assessment of construct validity by measuring correlation with SPRINT and SRGS-SF indicated satisfactory validity. The MD-PTG-VP provides an informative tool that can be employed to examine professionals' mental health and wellbeing following exposure to PMIE frequently encountered in animal care. Further evaluation is required to ascertain population norms and confirm score cut-offs that reflect clinical presentation. Once fully validated this instrument may be useful to quantify the frequency and intensity of positive and negative aspects of PMIE exposure on veterinary professionals so that accurate population comparisons can be made and changes measured over time.
