The present thesis aimed to investigate the relationships of friendship and their relationships with personality traits and human values. For this, four empirical articles were carried out. Article 1 sought to adapt and gather evidence of validity and reliability of the Friendship Quality Scale (FQS) for Brazil, which considered two studies. The first one had a non-probabilistic sample of 427 university students from the cities of Parnaíba and Teresina, with a mean age of 21.29 years (SD = 4.48). They answered the FQS and a sociodemographic questionnaire. The Factorial Exploratory Analysis (FEA) indicated a unifactorial solution, which after excluding some items, was only 18 items that explained 47% of the total variance (α = 0.93). In the second study, which aimed to investigate new evidence about the structure found, a non-probabilistic sample of 401 university students from the cities of João Pessoa and Cajazeiras, with a mean age of 20 years (SD = 4.83). The Factorial Confirmatory Analysis (FCA) corroborated the FQS unifactory model [χ² (135) = 215.53, p < 0.001, χ²/gl = 1.59, CFI = 0.99, TLI = 0.99, RMR = 0.08, SRMR = 0.06, RMSEA = 0.04(IC 90% = 0.03-0.05), α = 0.91]. Article 2, on the other hand, sought to adapt and gather evidence of validity and reliability of the Friendship Intimacy Scale (FIS), using a method similar to the first article, differing only in the applied instrument, which was the FIS. In the first study, FEA indicated a unifactorial structure with 29 items, total variance of 31.14% and α = 0.91. The FCA, performed in the second study, confirmed the structure found [χ² (377) = 532.18, χ²/gl = 1.41, p < 0.001, CFI = 0.98, TLI = 0.97, SRMR = 0.05 e RMSEA = 0.03 (IC 90%= 0.02-0.04), α = 0.90]. Article 3 aimed to investigate the influence of human values and personality traits on the quality and intimacy of friendship. For this, a non-probabilistic sample of 200 college students was included, with a mean age of 22.81 (SD = 5.35). They answered the FQS, FIS, Dark Triad Dirty Dozen (DTDD), the Virtuous Personality Inventory (VPI), the Basic Values Questionnaire (BVQ-18), and a Sociodemographic Questionnaire. The results revealed significant correlations between the attributes of the friendship and some of the inserted variables. From the results, two regressions were performed. In the first one, considering the types of orientation of the values as predictors, it was revealed that only gratitude, altruism and central values explained the intimacy [F (3, 163) = 9.82; p < 0.001; R² adjusted = 0.13] and the quality [F (3, 176) = 11.94; p < 0.001; R² adjusted = 0.15] of the friendship. In the second, considering the types of motivators, only gratitude, altruism and humanitarian values explained the attributes of friendship, namely: intimacy [F (3, 166) = 10.85; p < 0.001; R² adjusted = 0.15] and quality [F (3, 176) = 13.78; p < 0.001; R² adjusted = 0.18]. Finally, Article 4 turned to the construction of an explanatory model of friendship including as explainers the constructs virtuous personality and human values. There was a non-probabilistic sample of 200 college students, with a mean age of 21 years (SD = 4.24). They answered EQA, EIA, IPV, QVB-18 and a Sociodemographic Questionnaire. The result of the path analysis revealed that the model with the best indicators of goodness of fit was one in which the traits of virtuous personality, gratitude and altruism, and social values explained the attributes of friendship [χ² (6) = 5.38; p < 0.001; χ² / gl = 0.90, CFI = 1.00, TLI = 1.00; RMSEA = 0.00 (90% CI = 0.00 - 0.08)]. Thus, it was concluded that the objectives of each article were reached, which provided adapted measures to measure quality and intimacy of the friendship, as well as exhibited the power of the antecedent variables to explain such attributes, contributing to the construction of explanatory models in Article 4.
