摘要:The aim of this study was to determine the psychometric properties of a measurement instrument design for the evaluation of the occupational positive mental health. Based on the positive psychology, humanism, salutogenesis and ecological model, we developed a 40 items survey with a five-point Liker response option. A sample of 740 workers of different occupations answered the survey, taking an average of 15 minutes. The data analysis included exploratory factor analysis for the determination of factorial validity and Cronbach’s Alpha coefficient for reliability. The results indicated a four-factor structure that explains 43.55% of the total variance and a Cronbach’s Alpha of .923 for the whole instrument. We conclude that the SMPO-40 is a valid and reliable measurement instrument for the evaluation of the occupational positive mental health.
