Sexual Consent Perceptions of a Fictional Vignette: A Latent Growth Curve Model

The Effects of Alcohol Intoxication on Perceptions of Consent and Refusal Indicators in a Fictional Alcohol-Involved Sexual Encounter

Alcohol intoxication may influence how bystanders interpret other people's consent and refusal cues. We examined the effects of alcohol intoxication on participants' perceptions of characters' consent and refusal indicators in a fictional vignette depicting an alcohol-involved sexual encounter. Young adults (n = 119, 52% women) participated in an alcohol administration experiment examining the influence of acute intoxication on bystander perceptions during a vignette depicting a character who is intoxicated and declines a sexual advance from another character, who ignores her refusal and continues to pursue sexual activity. Participants were randomly assigned to an alcohol or non-alcohol condition and then guided through a semi-structured interview in which we asked about the characters' consent and refusal cues. Interviews were analyzed using both inductive and deductive coding. Most participants eventually indicated the encounter was nonconsensual, but approximately 9% of participants described the encounter as entirely consensual and another 42% of participants described the interaction as initially consensual and then nonconsensual. Participants discussed nuanced accounts of consent and refusal cues, including indicators related to alcohol consumption. Disregarding intoxication and gender, participants eventually recognized the situation as nonconsensual and thus potentially risky. However, some participants recognized this risk earlier in the encounter than others. Consequently, bystanders who recognize risk later in a situation may have fewer opportunities to intervene before a situation escalates. We recommend sexual assault prevention educators take a more nuanced approach when discussing consent and refusal indicators, emphasizing contextual factors that may indicate risk.

Adults' Understandings and Experiences of the Capacity to Consent to Substance-Involved Sexual Activity

Most research on capacity to consent to substance-involved sex has focused exclusively on the implications of alcohol with little attention given to other or additional psychoactive drugs. This study aimed to explore people's understanding and experiences of the capacity to consent to alcohol- and/or drug-involved sexual activity. UK adults (N = 354) completed an online mixed-methods survey on sexual consent during sober, alcohol- and/or drug-involved sex. Qualitative data were analyzed using thematic analysis. Themes for capacity to consent were: (1) "There is no normative understanding of substance-involved sexual consent," (2) "Moving beyond the binary of consciousness versus incapacitation" and (3) "Substance-involved sexual decisions are viewed as irresponsible." The findings illustrated that capacity to consent is nuanced and multidimensional, and that people's understandings and experiences of capacity to consent to substance-involved sex are not solely individual, but rather, they are also shaped by their environment. We call for a multidimensional view of capacity to consent, where a standard of "unimpaired," rather than sober, is used and modeled by academics, legislators, and educators.

Testing the Internal Consent Scale for Measurement Invariance Across Women and Men

The Internal Consent Scale (ICS) was created to measure feelings associated with a person’s willingness to engage in partnered sexual activity. Although previous studies using the ICS have assessed gender differences, evidence has not been provided to suggest that the ICS functions similarly for women and men. Using data from an online cross-sectional survey of adults (N = 874; 53.1% women), we subjected the 25-item ICS to tests of measurement invariance across gender. We found that only partial measurement invariance was tenable, which indicated that direct comparisons across gender should be interpreted with caution when using the ICS. Therefore, we created a gender-invariant short form. In support of construct validity, we found that this 15-item ICS–Short Form demonstrated similar associations with measures of sexual consent communication as the full 25-item ICS. If researchers aim to compare women and men on internal sexual consent, we recommend using the 15-item ICS–Short Form. Cognitive interviews should be conducted to further understand how women and men might differentially interpret ICS items.

Momentary versus Retrospective Sexual Consent Perceptions

Perceiving potential indicators of a person's willingness is an integral component of sexual consent. Preliminary qualitative evidence using vignettes suggested that consent perceptions can change over the course of a sexual scenario. In the present study, we extended previous research by directly comparing momentary and retrospective sexual consent perceptions using a quantitative study design. Employing a staggered vignette protocol, we examined participants' (n = 962; 72.0% female) momentary perceptions of fictional characters' sexual consent and compared them with participants' retrospective perceptions of the characters' consent. We hypothesized that participants would demonstrate a hindsight bias in that they would retrospectively indicate they thought the fictional characters were first willing to engage in sexual behavior earlier than when they did momentarily. We found that differences in participants' momentary versus retrospective perceptions of characters' sexual consent varied by the type of behavior. As we expected, participants demonstrated a hindsight bias for making out. Contrary to our hypothesis, participants were hesitant to retrospectively report that the characters were willing to engage in the other sexual behaviors (e.g., oral, vaginal, anal sex) at a point earlier than their momentary perceptions. That momentary and retrospective sexual consent perceptions significantly differ corroborates previous recommendations that sexual consent be conceptualized as an ongoing process.

Sexual Consent in Committed Relationships: A Dyadic Study

Sexual consent is a multidimensional construct that requires the participation of all involved in a sexual encounter; however, previous research has almost exclusively relied on one person's perspective. To address this, we collected open- and closed-ended data on sexual consent from 37 dyads in committed sexual relationships (N = 74). We found that relationship length was associated with sexual consent and couples who accurately perceived each other's consent communication cues reported elevated levels of internal consent feelings. Communicating willingness to engage in sexual activity remains important even within committed relationships. Preliminary findings suggest that further investigations of dyadic nuances of sexual consent are warranted.
