Confirmatory Factor Analysis of the Behavioural Regulation in Exercise Questionnaire – Portuguese Version

Exercise constitutes one of the pillars of a healthy lifestyle (USDHHS, 1996). Paradoxically, more than 40% of Europeans are sedentary (Eurobarometer 213, 2004), although some interventions, at both community and individual levels, have been established to improve this situation. Some of these interventions are based on Self-Determination Theory (SDT: Deci & Ryan, 1985), which state that more internalized types of behaviour regulation lead to feelings of selfdetermination in one’s chosen activities and, consequently, to greater likelihood of behavioural adherence. Today, SDT is one of the most popular approaches to the study of exercise, thus the cross-cultural validation of instruments that can measure its constructs is a necessary step to further advance in the study of exercise motivation.

Infidelidade e ciúme no relacionamento amoroso e sexual

RESUMO: O presente estudo tem como objectivo avaliar a relação, por género, entre a infidelidade, o ciúme e a satisfação sexual. Para tal foi utilizada uma amostra de 186 sujeitos, de ambos os sexos, que preencheram um protocolo que incluía como medidas de avaliação um questionário de dados demográficos,um de envolvimentos românticos e sexuais, um de reacções emocionais à infidelidade do parceiro, o Multidimensional Jealousy Scale (Pfeiffer & Wong, 1989), o Big Five Inventory (Benet-Martinez & Oliver, 1998) e o Index Sexual Satisfaction (Hudson, Harrison & Crosscup, 1981). Foram encontradas diferenças entre géneros face à infidelidade, sendo que os homens consideram pior uma infidelidade sexual e as mulheres uma infidelidade emocional. A insatisfação sexual associou-se positivamente ao ciúme, em ambos os sexos, contudo, nas mulheres associou-se positivamente a duas dimensões do ciúme enquanto nos homens apenas se associou a uma. O ciúme associou-se de forma positiva com alguns sentimentos como traição, engano, ódio, rejeição ou desilusão, face à infidelidade, em ambos os sexos, o que parece indicar que ambos os sexos reagem aos dois tipos de infidelidade, contudo diferenciam-se na experiência dos sentimentos a ela associados. ABSTRACT: This study aims to assess the relationship, by gender, between infidelity, jealousy and sexual satisfaction. To this end it was used a sample of 186 individuals of both sexes, who completed a protocol that included evaluating measures such as one questionnaire assessing demographic data, one of sexual and romantic entanglements, and another one of emotional reactions to infidelity of the partner, Multidimensional Jealousy Scale (Pfeiffer & Wong,1989), the Big Five Inventory (Benet-Martinez & Oliver, 1998) and Sexual Satisfaction Index (Hudson, Harrison & Crosscup, 1981). Gender differences were found in relation to infidelity, while men consider worse sexual infidelity, women consider it emotional infidelity. Sexual dissatisfaction was positively associated with jealousy in both sexes, however, in women it was positively associated with the two dimensions of jealousy while in men it was associated with only one. Jealousy was associated positively with some feelings of betrayal, deceit, hate, rejection or disappointment towards infidelity for both sexes, suggesting that both sexes respond to the two types of infidelity, however they differ when experiencing feelings associated with it.
