Using confirmatory factor analyses and multiple indicators per construct, we examined a number of theoretically derived factor structures pertaining to numerous trust-relevant constructs (from 9 to12) across four institutional contexts (police, local governance, natural resources, state governance) and multiple participant-types (college students via an online survey, community residents as part of a city’s budget engagement activity, a random sample of rural landowners, and a national sample of adult Americans via an Amazon Mechanical Turk study). Across studies, a number of common findings emerged. First, the best fitting models in each study maintained separate factors for each trust-relevant construct. Furthermore, post hoc analyses involving addition of higher-order factors tended to fit better than collapsing of factors. Second, dispositional trust was easily distinguishable from the other trust-related constructs, and positive and negative constructs were often distinguishable. However, the items reflecting positive trust attitude constructs or positive trustworthiness perceptions showed low discriminant validity. Differences in findings between studies raise questions warranting further investigation in future research, including differences in correlations among latent constructs varying from very high (e.g., 12 inter-factor correlations above .9 in Study 2) to more moderate (e.g., only 3 correlations above .8 in Study 4). Further, the results from one study (Study 4) suggested that legitimacy, fairness, and voice were especially highly correlated and may form a single higher-order factor, but the other studies did not. Future research is needed to determine when and why different higher-order factor structures may emerge in different institutional contexts or with different samples.

Self-Efficacy Theory (SET; Bandura, 1986, 2000) has generated research and practice ramifications across areas of psychology. However, self-efficacy has yet to be assessed in a legal context. The present paper juxtaposes self-efficacy with self-confidence in terms of theoretical foundations and practical implications, with attention to the area of witness testimony. It is concluded that the concept of witness self-efficacy possesses thorough theoretical grounding as a potential target for witness preparation. As such, we put forth an integrated model of witness preparation featuring self-efficacy bolstering techniques within an established witness training framework.

This study sought to identify stigma differences between HIV/AIDS and other sexually transmitted infections (STIs). Interviewees from Alabama, USA (n=537) rated two types of stigma (damage to social reputation and “moral weakness”) for seven infections ranging from “nuisance” conditions (e.g., pubic lice) to life-threatening disease (e.g., HIV/AIDS). When asked which of the seven STIs would be most damaging to reputation, 74.8% of respondents chose HIV/AIDS. However, when asked to choose which STI represented moral weakness in infected persons, HIV/AIDS was rated as significantly lower than the other STIs, which suggests that HIV/AIDS is perceived differently than non-HIV STIs. This study addresses the possibility that advances in public awareness of HIV/AIDS have not necessarily been extrapolated into awareness of other STIs. Clinicians should be aware of these high levels of stigma as potential barriers to treatment for all STIs. Public health officials should consider the impact of undifferentiated stigma on STI prevention messages.
