Keywords:
Personality, Positive psychology, Psychological tests, ValidationAbstract
Objective
This study aimed to investigate the psychometric properties of an assessment scale of human drive, understood as a trait. The construct consists of two components, consistency of interests and maintenance of effort. The scale used in this study was developed in Portuguese. The objective of this study was to investigate the internal structure, through the Exploratory and Confirmatory Factor Analysis, the accuracy rates, and the invariance of the scale regarding the nationality of the respondent.
Method
A total of 671 university students with a mean age of 26.53 (SD = 10.07) participated. A total of 77.8% were female.
Results
The results confirmed the structure of two factors (χ2/df = 1.83, GFI = 0.999, CFI = 0.994, RMSEA = 0.035 [0.024-0.046]), with excellent reliability (α = 0.85 and α = 0.86), and coefficient correlation 0.84 between the factors.
Conclusion
The scale invariance was confirmed.
