'I feel like a person has a right to use a product to protect themselves ': a qualitative study of the risk-benefit calculus on women's contraceptive use and choice.

Background Reducing pregnancy risk requires a multidimensional approach to sexual and reproductive health product development. The purpose of this analysis is to identify, compare, and contrast women's pre-use beliefs and attitudes about three different forms of contraceptives: intravaginal rings; spermicide in conjunction with condoms; and oral contraceptive pills - and explore how those attitudes and beliefs, along with actual method-use experience, may affect potential choices in contraceptive method moving forward. The relationship of beliefs and attitudes to their risk-benefit calculations when using these methods was also considered.? METHODS: Women used one or more contraceptive methods, each for 3-6 months. Qualitative data from individual in-depth interviews completed after each 3-month use period were analysed using a summary matrix framework. Data were extracted and summarised into themes. Each woman's experiences were compared among the methods she used; comparisons were also made across participants. RESULTS: The data consist of 33 90-120 min in-depth qualitative interviews from 16 women aged 20-34 years, in which they discussed various elements of their method use experience. One prominent theme was identified: the influence of attitudes and beliefs on the risk-benefit calculus. There were six key elements within the theme: pregnancy prevention; dosing and the potential for user error; side-effects; familiarity; disclosure; and sexual partnerships. CONCLUSIONS: Women weighed perceived risks and benefits in their decision-making and, ultimately, their contraception choices. Understanding women's beliefs and attitudes that contribute to a calculation of risk-benefit can inform the development of sexual and reproductive health products.

Developing Online Recruitment and Retention Methods for HIV Prevention Research Among Adolescent Males Who Are Interested in Sex with Males: Interviews with Adolescent Males.

BACKGROUND: Adolescent males interested in sex with males (AMSM) are an important audience for HIV prevention interventions, but they are difficult to reach due to their age and social stigma. OBJECTIVE: We aim to identify efficient methods to recruit and retain AMSM in online research. METHODS: Interviews with 14-to-18-year-old AMSM (N=16) were conducted at 2017 Pride events in Boston, MA and Providence, RI. RESULTS: Participants reported that (1) social media platforms are viable recruitment venues; (2) recruitment advertisements should describe the study using colorful/bright pictures, familiar words, and information about compensation; (3) surveys should be <20 minutes in length; (4) modest compensation (eg, email gift card, US $10 to $20) was preferred; and (5) communications that remind participants about the length and content of surveys, and compensation, should be sent between study activities to increase retention. CONCLUSIONS: Soliciting input from AMSM provides critical guidance regarding recruitment and retention procedures to increase the efficiency of HIV prevention research for this at-risk group.

Designing Dual Compartment HIV Prevention Products: Women's Sensory Perceptions and Experiences of Suppositories for Rectal and Vaginal Use.

Dual compartment suppositories are being developed to prevent HIV and other sexually transmitted infections. Such products, for use in the rectum, the vagina, or both, could have a significant public health impact by decreasing global incidence of these diseases. In this study, 16 women each used two rheologically distinct suppositories in their vagina and rectum. User Sensory Perception and Experience (USPE) scales assessed sensory experiences during sexual activity to understand whether, and how, women perceive formulation properties in the vagina and rectum. Qualitative data from individual in-depth interviews captured women's descriptions and comparisons of the experiences. Significant differences and large Cohen's d effect sizes between vaginal and rectal experiences of suppository-A were found for three scales: Application (APP): Product Awareness, SEX: Initial Penetration; and SEX: Effortful. Qualitative data provided user experience details that credibly align with these score differences. Near significant differences and large effect sizes were found for two additional scales: SEX: Perceived Wetness with suppository-A and SEX: Messiness with suppository-B. In addition, other scale scores showed medium-to-large effect sizes that correspond to hypothesized sensations associated with biophysical properties of the suppositories. Statistical significance combined with large effect sizes and qualitative data accurately represent the hypothesized perceptibility of suppository properties and identifies performance characteristics relevant to acceptability and adherence; together these data provide discernment of factors that can guide the development of dual compartment products. The Clinical Trial Registration number: NCT02744261.

A Qualitative Study of the Contraceptive Effect on Women's Sexual Experiences: Beyond Hormonal Effects.

OBJECTIVE: To elucidate the effects of the intravaginal ring, oral contraceptive pill (OCP), and spermicide plus condom on women's sexual experiences through an in-depth understanding of the physical characteristics of these contraceptive methods. METHODS: We conducted qualitative in-depth interviews with women (aged 18-45 years) who used up to three contraceptive methods (intravaginal ring, OCP, and spermicide plus condom). Women completed in-depth interviews after each 3-month use period. We used a summarized matrix framework and thematic content analysis to explore how each method affected participants' sexual experiences. RESULTS: Sixteen women completed interviews, yielding 33 transcripts. Women reported physical effects on their sexual experiences while using the intravaginal ring and spermicide plus condom. The OCP was often discussed as lacking these physical effects. Discussion themes included product administration (eg, navigating intravaginal ring removal) and physical product awareness (eg, spermicide as a lubricant). From these experiences, women often altered and individualized their use and subsequent opinions of the contraceptive method. CONCLUSION: The range of contraceptive effects on women's sexual experiences shape their use and opinions of the product, leading to either increased motivation and consistent use or poor adherence and discontinuation. Awareness of these individualized experiences can help providers better understand and guide their patients towards successful contraceptive use.

User evaluations offer promise for pod-intravaginal ring as a drug delivery platform: A mixed methods study of acceptability and use experiences.

BACKGROUND: Effective HIV prevention requires efficient delivery of safe and efficacious drugs and optimization of user adherence. The user's experiences with the drug, delivery system, and use parameters are critical to product acceptability and adherence. Prevention product developers have the opportunity to directly control a drug delivery system and its impact on acceptability and adherence, as well as product efficacy. Involvement of potential users during preclinical design and development can facilitate this process. We embedded a mixed methods user evaluation study into a safety and pharmacokinetics (PK) trial of a pod-intravaginal ring delivering antiretroviral agents. METHODOLOGY: Women enrolled in two cohorts, ultimately evaluating the safety/PK of a pod-IVRs delivering TDF-alone, TDF-FTC, and/or TDF-FTC-MVC. A 7-day use period was targeted for each pod-IVR, regardless of drug or drug combination. During the clinical study, participants provided both quantitative (i.e., survey) and qualitative (i.e., in-depth interview) data capturing acceptability, perceptibility, and adherence behaviors. Initial sexual and reproductive health history surveys, daily diaries, a final acceptability and willingness to use survey, and a qualitative in-depth interview comprised the user evaluation data for each pod-IVR experienced by the participants. FINDINGS: Overall, the majority of participants (N = 10) reported being willing to use the pod-IVR platform for HIV prevention should it advance to market. Confidence to use the pod-IVR (e.g., insertion, removal) was high. There were no differences noted in the user experience of the pod-IVR platform; that is, whether the ring delivered TDF-alone, TDF-FTC, or TDF-FTC-MVC, users' experiences of the ring were similar and acceptable. Participants did report specific experiences, both sensory and behavioral, that impacted their use behaviors with respect to the ring, and which could ultimately impact acceptability and adherence. These experiences, and user evaluations elicited by them, could both challenge use or be used to leverage use in future trials and product rollout once fully articulated. CONCLUSIONS: High willingness-to-use data and lack of salient differences in user experiences related to use of the pod-IVR platform (regardless of agents delivered) suggests that the pod-IVR is a feasible and acceptable drug delivery device in and of itself. This finding holds promise both for an anti-HIV pod-IVR and, potentially, a multipurpose prevention pod-IVR that could deliver both prevention for sexually transmitted infections (STIs) including HIV and contraception. Given the very early clinical trial context, further acceptability, perceptibility, and adherence data should continue to be explored, in the context of longer use periods (e.g., 28-day ring use), and in the contexts of sexual activity and menses. Using early design and development contexts to gain insights into potential challenges and facilitators of drug delivery systems such as the pod-IVR could save valuable resources and time as a potential biomedical technology moves through the clinical trial pipeline and into real-world use.

User input in iterative design for prevention product development: leveraging interdisciplinary methods to optimize effectiveness.

The development of HIV-preventive topical vaginal microbicides has been challenged by a lack of sufficient adherence in later stage clinical trials to confidently evaluate effectiveness. This dilemma has highlighted the need to integrate translational research earlier in the drug development process, essentially applying behavioral science to facilitate the advances of basic science with respect to the uptake and use of biomedical prevention technologies. In the last several years, there has been an increasing recognition that the user experience, specifically the sensory experience, as well as the role of meaning-making elicited by those sensations, may play a more substantive role than previously thought. Importantly, the role of the user-their sensory perceptions, their judgements of those experiences, and their willingness to use a product-is critical in product uptake and consistent use post-marketing, ultimately realizing gains in global public health. Specifically, a successful prevention product requires an efficacious drug, an efficient drug delivery system, and an effective user. We present an integrated iterative drug development and user experience evaluation method to illustrate how user-centered formulation design can be iterated from the early stages of preclinical development to leverage the user experience. Integrating the user and their product experiences into the formulation design process may help optimize both the efficiency of drug delivery and the effectiveness of the user.
