Spanish version of the Investment Model Scale

Voluminous work has catalogued the utility of Rusbult's (1980) investment model of commitment processes in understanding why some relationships persist whereas others fail. To date this work has been conducted almost exclusively with samples of English‐speaking individuals. To facilitate testing novel hypotheses among Spanish‐speaking populations as well examining various cross‐cultural questions, we present a Spanish version of the Investment Model Scale (Rusbult, Martz, & Agnew, 1998). With a sample of Spanish‐speaking individuals from Chile, we demonstrate that our translation has the same structural properties as the English version (Study 1) and has good predictive validity (Study 2). The Spanish version of the Investment Model Scale will enable researchers to sample a larger subset of the population and allow for the examination of cultural influences on relationship processes.     

Pluralistic ignorance in revenge attitudes and behavior in interpersonal relationships

We investigated whether people's perceptions of social norms concerning interpersonal revenge reflect a tendency for individuals to believe that others' revenge attitudes and behavior differ from their own (i.e., pluralistic ignorance). As part of a survey on revenge experiences in relationships with romantic partners, family members, and associates (e.g., friends), participants (N = 534) judged the acceptability and frequency of revenge in significant personal relationships. As expected, participants believed that others (a) saw revenge as more acceptable and (b) engaged in revenge more frequently than they did themselves. They did not, however, perceive others' revenge attitudes and behaviors to be any more variable than their own attitudes and behaviors actually were. Explanations for and implications of these findings are discussed.     

Pluralistic ignorance and misperception of social norms concerning cheating in dating relationships

Two studies tested the hypothesis that beliefs about infidelity in dating relationships reflect pluralistic ignorance, a misperception in which people mistakenly believe that their own personal attitudes and behavior differ from others' when they do not. Consistent with pluralistic ignorance findings in other domains, undergraduates reported that the average university student (a) saw dating infidelity as more acceptable and (b) engaged in unfaithful acts more frequently than they themselves did. Neither type of infidelity (sexual, emotional, both sexual and emotional, or unspecified; Study 1, N = 176) nor motivated reasoning (i.e., defensiveness; Study 2, N = 359) moderated this pattern of results. Possible sources of misperceived norms concerning fidelity in dating relationships and the implications of such misperceptions are discussed.
