RESUMEN
BACKGROUND: This research presents a short version of the Professional Quality of Life (ProQOL) scale, one of the most frequently used questionnaires in the arena of applied healthcare investigation. It measures burnout (BO), compassion fatigue (CF), and compassion satisfaction (CS). METHODS: A 9-item version of the ProQOL was developed. In Study 1, this short version, which used items from version IV of the ProQOL, was administered to 817 palliative care professionals from Spain, Argentina, and Brazil. In Study 2, the same nine items, but this time from version V of the ProQOL, were administered to 296 Spanish palliative care professionals. RESULTS: Study 1: The Short ProQOL showed an adequate internal structure, and invariance across the countries studied (χ2(106) = 185.620 (p < 0.001), CFI = .929, RMSEA = 0.058 [0.044, 0.072], SRMR = 0.081). Argentinians showed higher levels of BO (mean difference = 0.172, p = 0.042, Cohen's d = 0.168), whereas Brazilians showed higher levels of CF (Mean difference = 0.384, p = 0.002, Cohen's d = 0.352). Study 2: the Short ProQOL again showed adequate internal structure and reliability (χ2(24) = 134.504 (p < 0.001); CFI = 0.953; RMSEA = 0.126 [0.106, 0.147]; SRMR = 0.063), and was related to coping with death, self-compassion, and self-care. CONCLUSIONS: The Short ProQOL could help facilitate the application of harmonizing measurements and its use for cross-cultural comparisons and occupational health monitoring was satisfactory.
