Sexual Consent at First-Time Intercourse: Retrospective Reports from University Students in Canada and the United States

Associations Between Recent Contraceptive Use and First Sex Behaviors of Scottish Adolescents: A Brief Report

Objectives

We examined associations between recent contraceptive use and first-sex behaviors (early initiation, substance use, contraceptive use) among adolescents in Scotland.

Methods

We used data from the Health Behavior in School-aged Children study.

Results

Controlling for early initiation and substance use, girls and boys who used contraceptives at first sex were 7.5 and 12.3 times more likely to use contraceptives at most recent sexual intercourse than adolescents who did not (p < .001). We also present preliminary evidence on contraceptive use of Scottish adolescents in 2022.

Conclusions

Experiences during adolescents' first sex may have lasting implications for later sexual behavior.

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.

Assessing the Within-Person Variability of Internal and External Sexual Consent

Sexual consent is often conceptualized as an internal willingness to engage in sexual activity, which can be communicated externally to a sexual partner. Internal sexual consent comprises feelings of physical response, safety/comfort, arousal, agreement/want, and readiness; external sexual consent includes communication cues that may be explicit or implicit and verbal or nonverbal. Most previous research on sexual consent has focused on between-person differences; little attention has been devoted to examining the within-person variation of sexual consent across time. We conducted a 28-day experience sampling methodology (ESM) study with a sample of adults (N = 113) to assess fluctuations in internal and external sexual consent across a given person's sexual events. We found that more than 50% and up to 80% of the variance in sexual consent scores could be accounted for by within-person variability. The type of sexual behavior participants engaged in during a sexual event predicted their internal and external consent. Further, internal consent feelings predicted external consent communication. Overall, our findings provided initial evidence regarding the extent that situational contexts are relevant for sexual consent. ESM study designs may be used to further investigate the potential contextual, intrapersonal, and interpersonal factors associated with internal and external sexual consent.

Developing Valid and Feasible Measures of Sexual Consent for Experience Sampling Methodology

Preliminary evidence indicates that people's sexual consent (i.e., their willingness to engage in sexual activity and communication of that willingness) varies across time and context. Study designs that assess sexual consent at multiple time points (e.g., experience sampling methodology [ESM]) are needed to better understand the within-person variability of sexual consent. However, extant validated measures of sexual consent are not appropriate for ESM studies, which require shorter assessments due to the increased burden this methodology has on participants. As such, the goal of the present study was to develop ESM measures of sexual consent based on items that have previously been validated for use in cross-sectional surveys. We selected items that balanced face validity as evidenced by cognitive interviews (n = 10) and content validity as evidenced by experts' ratings (n = 6). To assess the construct validity and feasibility of these items, we administered the selected ESM measures of sexual consent in a seven-day pilot study (n = 12). The results suggested that the ESM measures developed in the present study were a valid and feasible assessment of people's experience-specific internal consent feelings and external consent communication. We conclude with recommendations for sex researchers interested in ESM.
