This study aims to verify if there is any difference in the personality traits of Project Managers with different professional backgrounds – training, experience, and business sector (public or private). Using as theoretical basis the Big Five personality traits, this research was conducted with 244 Project Managers who work in Brazil. The results of tests of mean differences between groups showed that Project Managers with more experience have the trait agreeableness more pronounced than managers with less experience, while Project Managers with more schooling have a higher Conscientiousness, Openness to Experience, and Emotional Stability than Managers with less schooling. Project Managers who work in the public and private sectors showed different personality traits between themselves, and only for agreeableness no significant difference was found. These findings may contribute to the targeting of selection and training policies and the development of interpersonal and technical ...
NEO-FFI: Psychometric properties of a short personality inventory in Portuguese context
Psicologia: Reflexão e Crítica, 2014
The aim of this study was to assess the psychometric properties (validity and reliability) of the Portuguese adaptation of the NEO Five-Factor Inventory (NEO-FFI) and to compare the obtained structure to the original North American version. The methods of analysis used for cross-validation of the factorial structure were the Principal Axis Factoring (PAF) and the Confi rmatory Factor Analysis (CFA). PAF reproduced the original structure of NEO-FFI and CFA revealed a satisfactory fi t of single-factor models for the fi ve dimensions. The reliability analysis showed high values of internal consistency which are congruent with previous international adaptations of the NEO-FFI. Multidimensional analysis showed signifi cant main effects of gender and academic qualifi cations on personality using age as covariant. The fi ndings suggest that the Portuguese version of the NEO-FFI is a reliable instrument to measure the fi ve dimensions of personality.
Psychometric properties of the Brazilian version of the big five inventory
Trends in Psychiatry and Psychotherapy, 2023
Introduction: There is growing interest in the fields of psychiatry and psychology in investigating the relationship between personality and psychopathology. The Big-5 is a model developed to investigate five personality dimensions: Extroversion, Agreeableness, Conscientiousness, Neuroticism, and Openness. In the present study, we describe the process of translation into Brazilian Portuguese and adaptation of a free tool to evaluate the Big-5 model: The Big-5 Inventory (BFI). The instrument has 44 items with a Likert response scale ranging from 1 to 5. Objectives: To translate and adapt the BFI into Brazilian Portuguese. Methods: The adaptation was conducted in the following steps: 1) Translation, 2) Evaluation Committee, 3) Back-translation, 4) Pilot study, 5) Evaluation Committee, and 6) Application. The sample comprised 490 participants from various regions of Brazil. The participants' ages ranged from 18 to 71 years, most of them had completed high school (62.9%), and the majority were women (75%). Results: A model with the following fit indexes was found: χ²/df: 1.954; goodness fit index (GFI): 0.924; comparative fit index (CFI): 0.920; and root mean square error of approximation (RMSEA): 0.044. Conclusion: The results are suggestive that the Brazilian version of this instrument has good psychometric properties and represent a cost-free option for investigating associations with the Big-5 in psychiatry.
Frontiers in psychology, 2018
The importance of quickly assessing personality traits in many studies prompted the development of brief scales such as the Ten-Item Personality Inventory (TIPI), a measure of five personality traits (extraversion, agreeableness, conscientiousness, emotional stability, and openness). In the current study, we present the Portuguese version of TIPI and examine its psychometric properties, based on a sample of 333 Portuguese adults aged 18 to 65 years. The results revealed reliability coefficients similar to the original version (α = 0.39-0.72), very good 4-week test-retest reliability ( = 81, s > 0.71), expected factorial structure, high convergent validity with the Big-Five Inventory (s > 0.60), and correlations with self-esteem, affect, and aggressiveness similar to those found with standard measures of personality traits. Overall, our findings suggest that the Portuguese TIPI is a reliable and valid alternative to longer measures: it offers a promising tool for research conte...
The Inventory of Personality Organization (IPO) is a self-report instrument to access psychological functions for the structural diagnosis according to the Model of Personality Organization. Objective: The aim was to translate and adapt the IPO for use in the Brazilian language and culture. Method: The synthesized version was examined by a committee of three experts to evaluate the clarity, appropriateness and semantic equivalence to the Brazilian culture. The resulting version was evaluated by a focal group, composed of four adults with secondary education, which analyzed the familiarity of items. Next, a pilot application to a 10 subject group was performed to identify possible difficulties in understanding and filling the inventory. A back-translation of the adjusted instrument was submitted to the authors of the original IPO for validation. Results: From 83 items translated, 48 were modified by the committee of experts, 12 by the focal group, 2 after the pilot application and 2 after the back-translation procedure. In total, 50 (60.2%) items were modified. Conclusions: Herein we have structured the trial version of IPO-Br. The resulting instrument is adjusted to the Brazilian sociocultural reality and maintain equivalence with the original version.
Cattell’s Personality Factor Questionnaire (CPFQ): Development and Preliminary Study
This study was aimed at: (a) developing an instrument for personality assessment according to Cattell's model, in which the 16PF is based on; and (b) carrying out an empirical analysis of the internal structure of the instrument. Three hundred and forty seven people, mostly female (67.4%), attending higher education (62.5%) and aged between 16 and 66 (M = 25.69; SD = 8.90) participated in the study. One hundred and twenty items were created and an exploratory factor analysis of the main factors was carried out. Then, a parallel analysis, an exploratory full information factor analysis with categorical variables and an internal consistency analysis were performed. The results suggest that the instrument is composed of 12 factors of reasonable internal consistency rates. The model developed by Cattell helped to understand the structural organization found for the instrument, since there is coherency, especially in relation to more general terms (global factors).
A Short Version of the Big Five Inventory (BFI-20): Evidence on Construct Validity
Revista Interamericana de Psicología/Interamerican Journal of Psychology
Several measures were developed in the past decades to measure personality, focusing on the Big Five Factor Model (BFFM; Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism). Despite the relevance of their findings in different countries, a shared limitation of such measures is their length, demanding time from researchers and participants, which might cause boredom or fatigue, biasing the final results. This research aimed to provide a shorter version for the 44-Item Big Five Inventory (BFI), through two studies (NTotal = 8,119). The structure was assessed using a range of techniques (e.g., PAF analysis, Procrustes rotation). The best 20 items (4 per factor) were chosen to compose the final version of the BFI-20, which presented suitable psychometric evidences across the samples. Thus, due the growing need for shorter measures without losing their psychometric quality, our findings indicate the adequacy of the 20-item BFI and its potential applicability in res...
