For this study, we translated the WRQoL Scale into Brazilian Portuguese and validated this version, which showed adequate psychometric properties and evidence that the scale is relevant for assessing Work-Related Quality of Life. The Cronbach's alpha (α = 0.94) of this version was higher than those of the original scale (α = 0.91) [15] and other translations [26–30]. However, differences were found between the present results and the original scale and the other translated versions. In the Brazilian Portuguese version of the WRQoL scale, the following factors were confirmed: General Well-Being (10 items), Home-Work Interface (3 items), Working Conditions (4 items), and Capacity and Ability (4 items).
There are some possible explanations for the divergences between the Brazilian version of the WRQoL scale and the original scale in English and other languages. First, CFA was not conducted for some translated versions, which may have resulted in a different number of items and factors. The focus group suggested that some translated terms needed to be modified to enhance the understanding of the target audience. Most of the target audience comprised self-employed professionals or workers from institutions. Furthermore, this translation was a first for a Latin American country, and it may differ from translations in European and Asian countries because of the language and culture [31]. However, the psychometric properties and structure of the Brazilian Portuguese version are strongly supported by the statistical analyses performed.
Analysis of the responses in the LSS revealed that over 50% of the sample expressed satisfaction and extreme satisfaction with their lives. This result likely indicates a sense of self-realization both personally and professionally, which was also observed by Moreno-Milan et al. [32].
A significant portion of the participating professionals presented moderate to high levels of EE and DP (79% and 60.2% respectively), indicating a high level of burnout, which is higher than the values reported by Simionato and Simpson [6] for psychotherapists (54.54% of the sample). Despite the levels of EE and DP, high personal accomplishment (PA) was prevalent. This finding is consistent with previous studies on health professionals [33–35], which indicates that despite experiencing burnout, health professionals have adequate levels of PA. This may be due to the association of this work with the perception of being useful and contributing to the development of others [3, 10].
Of the three dimensions of burnout, EE was the most prevalent in the present sample, and it has been found in samples of healthcare professionals, such as physicians and nurses [7, 12, 36]. Other studies on psychotherapists indicate the presence of moderate to high levels of EE, with percentages ranging from 32.01% [6] to 47.9% [10].
The three dimensions of the Burnout scale correlated negatively with the four factors of the WRQoL scale as well as the overall scale. This indicates a negative association between psychologists' burnout and quality of work life, which was also found by Kim et al. [37] in their survey of nurses. The balance between personal life and work is reported in the literature as predictive of burnout [6, 38]. In other words, higher levels of burnout are associated with lower levels of WRQoL in the "Home-work interface," indicating a moderate association between these two factors [11].
In literature, the negative association between WRQoL and burnout is portrayed through ergonomic problems, work pressure, and factors in the work context, such as high psychological, emotional, cognitive, and psychic demands and a lack of favorable working conditions [11, 39]. Hence, conducting an in-depth study on the actual working conditions of psychologists could facilitate interventions aimed at enhancing their working conditions.
The “personal accomplishment” dimension in Burnout and its negative correlation with the “Capacity and Ability” domain of the WRQoL scale could be attributed to the diminished sense of competence to fulfill work responsibilities [4]. Hammond et al. [2] identified intensive work demands on psychologists, which require additional effort and skills to manage.
In agreement with a previous study [15, 40], they identified that overall life satisfaction influences WRQoL. Life satisfaction is positively associated with the sense of being better prepared to develop new skills [41].
In general, the participants showed adequate levels of life satisfaction, despite the data being collected during the pandemic. Perhaps this finding stem from the nature of the psychologist's profession, as they may have felt useful to others [3] heightened by the perception of contributing to a global phenomenon, namely, the increase in mental health demand during the pandemic period [42].
Finally, this study has limitations and strengths. A limiting factor is the period of data collection, which was at the beginning of the COVID-19 pandemic. This is because some findings in the literature indicate changes in the mental health of healthcare professionals during this period [43, 44].
On the other hand, the present study has strengths that contribute to the reliability of its results. These points include: diversity of activities among psychology professionals; participation of professionals from all over Brazil; use of different sub-samples for exploratory and confirmatory factor analyses; use of different instruments based on the international scientific literature to assess aspects of psychologists' mental health.
