Abstract
IntroductionBoth original Big Three Perfectionism Scale (BTPS; Smith et al. 2016), and the Portuguese version validated with a sample of university students (Lino et al. 2018) evaluates three second-order factors (rigid, self-oriented and narcissistic perfectionism) and ten facets.ObjectivesTo confirm the BTPS three-factors-ten-dimensions’ structure in a sample of Portuguese adults from the general population.MethodsA sample of 467 adults (70.7% females; Mean age=38.44±12.27; range: 25-82) answered the BTPS Portuguese version and other validated perfectionism measures (Multidimensional Perfectionism Scales from Frost and Hewitt & Flett; Self-Presentation Perfectionism Scale). To study the temporal stability a sub-sample of 132 participants completed the BTPS again after approximately five weeks. SPSS and AMOS software was used.ResultsThe second order model presented an acceptable fit (X²/df=3.115; TLI=.811; CFI=.825; RMSEA=.067). There was also evidence of a general factor comprising all the 45 items (X²/df=3.127; TLI=.809; CFI=.823; [JA1] RMSEA=.068). The Cronbach alphas of the three factors ranged from a=.88 to a=.92; and facets had a>.70 showing a total of a=.94. Total and dimensional scores showed significant positive and moderate to high correlations with the other perfectionism measures and their test-retest correlation coefficients were r=.85 (p<0.001).ConclusionsThis study confirms the validity and reliability of the Portuguese BTPS underlying three-factors structure. Additionally, we found, for the first time, that BTPS can also be validly and reliably used to measure a global perfectionism construct. It is our intention to develop a shorter version the Portuguese BTPS in the near future.
Highlights
The development of complex human-machine systems has led to greater demands on operators’ skills, and has increased the importance of human error (Pribytkova et al, 2012; Vondráčková et al, 2017; Jian Ai Yeow, 2014)
In the operators’ group significant correlations (Spearman’s test) were found between the level of quality of complex sensorimotor reactions and the level of such personal traits as impulsiveness and individualism: a higher manifestation of these traits was associated with a higher level of mistakes in conducting the pre-shift psychophysiological test (p
The results suggest that a tendency to behave spontaneously, and orientation to one’s own needs, could be risk factors in terms of operator reliability
Summary
Conscientiousness, extroversion, agreeableness and neuroticism are known as the Big Five personality traits (BFPT). They are theoretical building blocks of the personality and comprise wide and interconnected spectra. The AI was conservatively tuned to maximize the oneway random intraclass correlation coefficient (ICC) between predicted and real values. The results for extroversion and agreeableness were indicative of fair performance
