Objective: Food cravings play an important role in the neurobiology of appetitive behavior, being positively associated with negative feelings, eating disorders, and obesity. This study aimed to assess the psychometric properties of the Brazilian Food Cravings Questionnaire-Trait-reduced (FCQ-T-r), a short version of the most widely used measure of this behavior. Methods: Undergraduate students (n=505) completed the full version of the FCQ-T and the Three-Factor Eating Questionnaire. Respondents’ height and weight were also measured. Exploratory factor analyses were performed. Results: The FCQ-T-r exhibited a single-factor structure and satisfactory internal consistency (α > 0.80). A positive correlation was observed between FCQ-T-r scores and those of the original version. Furthermore, FCQ-T-r scores correlated positively with uncontrolled eating and emotional eating behaviors. No correlation was found between body mass index and FCQ-T-r scores. Considering our sample characteristics, we suggested specific FCQ-T-r cutoff points for males and females in the Brazilian population. Conclusion: Our results support the structure of the Brazilian adaptation of the FCQ-T-r, which seems to be a viable instrument to investigate food cravings, particularly in time-constrained settings. Further studies are needed to verify these findings in other age ranges and clinical samples.

A crescente indústria do turismo tem se estendido ao ambiente aquático, deste modo tornando os mamíferos aquáticos suscetíveis a interações com humanos. O turismo de observação de golfinhos na praia de Pipa litoral sul do Rio Grande do Norte, tem se desenvolvido aumentando o número de barcos de observação de golfinhos operando nesta área. No presente estudo alterações comportamentais do Sotalia guianensis (Van Bénédén, 1864) causado pela presença destes barcos foi verificada. Registros comportamentais de S. guianensis foram compilados de um ponto fixo do alto de uma falésia próxima à área de estudo. As observações foram realizadas quando não havia barcos, na presença de barcos e após a saída dos barcos. Os resultados mostraram que o tipo de aproximação praticado pelos barcos de observação de golfinhos tinha maior influência no comportamento dos animais, especialmente em grupos com filhotes. Os impactos de curto prazo foram mais discretos, no entanto, novos métodos devem ser aplicados no sentido de verificar impactos de longo prazo no comportamento dos golfinhos.

The ever-increasing tourist industry has extended to the aquatic environments, thus making the aquatic mammals susceptible to interactions with humans. Dolphin watching tourism has developed to a great extent in the Pipa Beach, Rio Grande do Norte, consequently the number of dolphin-watching boats operating in this area has increased. In the present study the behavioral alterations of Sotalia guianensis (Van Bénédén, 1864) caused by the presence of these boats were verified. Behavioral registers of S. guianensis were compiled from a fixed point on the cliffs close to the study area. The observations were effected when there were no boats, in the presence of boats and after the departure of boats. The results show that type of approach by the dolphin watching boats had a major influence on the behavior of the dolphins, especially so in the groups with calves. The short term impacts were rather discrete, however, new methods should be applied in order to verify the long term impacts on the dolphins.
