[Measurement of the evaluative capacity of the CVP-35 questionnaire for perceiving the quality of professional life].

objectiveTo establish the CVP-35 evaluative properties to measure the professional quality of life (PQL).

designProspective, observational study.

settingA primary care area in the Community of Madrid, Spain.

participantsA total of 149 sanitary workers with some burnout sign measured by Maslach Burnout Inventory (MBI) participated. MEASUREMENTS: They fulfilled MBI, Goldberg Health Questionnaire (GHQ-28), and CVP-35 questionnaires at the beginning and after a year of follow-up, in which 73 subjects took part in activities for coping stress. It was assessed the change of PQL and their domains managerial support (PQL-MS), work load (PQL-WL), intrinsic motivation (PQL-IM) for the subjects with variations at the MBI, or GHQ-28 punctuation greater than 0.5 SD of the initial distribution.

resultsVariations in CVP-35 and their domains correlate weakly with changes in MBI and GHQ-28 (r<0.500), but they are congruent with the conceptual model. In the individuals with significant variations in the GHQ-28, they appreciate an average change in PQL and their domains between 0.18 and 0.55 points (absolute value). In those with significant variations in the MBI domains, PQL presented average absolute variations between 0.23 and 0.45 points, PQL-MS between 0.30 and 0.67, PQL-WL between 0.01 and 0.55 and PQL-IM between 0.22 and 0.83 points.

conclusionsCVP-35 is a sensitive-to-change instrument under population point of view. Changes in PQL perception or in any of their domains of 0.5 points could be pointed as relevant.
