This study aimed to explore the psychometric parameters of the Dula Dangerous Driving Index (DDDI) in Brazil. Four hundred and forty drivers (Mage=29.6; SDage=10.01) divided into two groups with 220 participants each, regrouped to evaluate the concurrent validity of the concise version of the measure. With the first group, the DDDI three-factor structure was verified, presenting acceptable reliability, difficulty and discrimination of the items. Based on previous analysis, 15 items were selected, testing their factor structure with the second group of participants, observing acceptable fit indexes (GFI=.99; RMSEA=.03). The concurrent validity was verified based on correlations between the DDDI, its subscales and the number of fines received by the drivers, involvement in infractions, traffic accidents and fights. The results provided evidences supporting the DDDI adequacy, which can be a useful tool to understand the antecedents and consequences of risk actions in traffic. [ABSTRACT FROM AUTHOR]

This study aimed to adapt the Intentions Toward Infidelity Scale (IIS) to the Brazilian context, knowing its psychometric parameters. Two studies were carried out with people who were in a romantic relationship. Study 1 included 161 participants (mean age = 24.9), who responded to the IIS and demographic questions. Results indicated the one-factor solution for this scale (α = 0.85), whose items showed reasonable discriminative power (theta ranging from -0.5 to 3.0). Study 2 included 236 participants (mean age = 25.5), who answered the same instruments. Results supported the one-factor structure (e.g., CFI = .95 and TLI =.93), which showed invariant across sex (ΔCFI and ΔRMSEA < 0.01). In conclusion, the findings supported the adequacy of the IIS items, but also indicated evidence of its factorial validity and internal consistency, favoring its use in studies looking to investigate the correlates of infidelity.
