Daily Relationship Functioning and Disordered Eating Behaviors Among Sexual Minority Women in Same-Sex Relationships.

BACKGROUND AND PURPOSE: The present study aimed to examine associations between different types of relationship functioning and disordered eating behaviors (DEBs) in the everyday lives of sexual minority women in same-sex relationships-an at-risk population that has not been assessed in this context. METHODS: Participants included 321 young sexual minority women (Mage = 27.56, SD = 3.67) in same-sex relationships who completed surveys assessing their daily relationship functioning and DEB use each day for a 14-day daily diary period. Multilevel structural equation modeling was used to examine daily-, person-, and couple-level associations among women's daily relationship functioning (general relationship functioning, positive and negative relational behaviors they and, separately, their partners engaged in) and DEBs (overeating, loss of control eating, emotional eating, and dietary restriction). RESULTS: Results generally indicated that more positive and less negative daily relationship functioning across all assessed constructs was associated with less same-day emotional eating. In contrast, associations between all daily relationship functioning constructs and loss of control eating were not significant, nor were any relationship functioning-DEB associations at the couple level. More circumscribed patterns of association were identified for associations between the relationship functioning constructs, and overeating and dietary restriction. CONCLUSIONS: Collectively, these findings provide insight into how aspects of daily relationship functioning map onto sexual minority women's daily engagement in DEBs that are linked to poor health long-term, and directions for future research and clinical practice that may warrant consideration moving forward to help advance the evidence-base and care for this historically overlooked and underserved population.

The present study examined associations between different types of relationship functioning (e.g., general relationship functioning, positive and negative relational behaviors that participants and their partners engaged in during their interactions with one another) and disordered eating behaviors (DEBs) in the everyday lives of sexual minority women in same-sex relationships. Results generally indicated that on days when women reported more positive and less negative daily relationship functioning, they also reported less emotional eating that day. In contrast, associations between different types of daily relationship functioning and loss of control eating were not significant. Furthermore, associations between different types of daily relationship functioning relative to overeating and dietary restriction varied based on the type of relationship functioning and DEB under consideration. Collectively, these findings provide insight into how different types of daily relationship functioning map onto sexual minority women's daily engagement in DEBs that are linked to poor health long-term. These findings also provide directions for future research and clinical practice that may warrant consideration moving forward to help advance the evidence base and care for this historically overlooked and underserved population.

Event-level drinking intentions, social drinking contexts, and motives affect alcohol consumption among same-sex female couples.

OBJECTIVE: Young sexual minority women (SMW; e.g., lesbian, bisexual women) are at increased risk for heavy drinking, though SMW in relationships may be at less risk than those who are single. The current study examined how SMW partners influence drinking in the moment, if own intentions predict drinking beyond partner influence and if this association is moderated by partner influence, and if own drinking motives moderate partner influence. METHOD: Young adult same-sex female couples (N = 162 couples) were recruited to participate in a 14-day daily diary study where they reported each morning their drinking intentions, motives, and behavior as well as whether their partner was present during drinking occasions. RESULTS: Findings from multilevel structural equation models revealed that own intentions and select partner influences (i.e., intentions, drinking) were uniquely linked to a greater quantity of drinking at the within-subject level. Significant interactions between own intentions and partner intentions, and between partner intentions and select drinking motives (social and enhancement) on same-day alcohol use were found at the within-subject level. CONCLUSIONS: Findings suggest that partner influences have a strong effect on drinking at the daily level, and can be strengthened or weakened when drinking for specific reasons. These findings expand on prior daily diary research on the effects of drinking motives by examining how these processes unfold in same-sex female couples and their intersection with partner intentions.

Refining an ecological momentary assessment study of binge eating among sexual minority and heterosexual young women: a mixed methods pilot study.

Background: Ecological momentary assessment (EMA) is used to capture daily lived experiences, states, and environments. Although EMA is commonly used in behavioral health research, there remains a dearth of literature on how researchers account for design considerations of EMA techniques when designing studies. The goal of this formative mixed methods study was to elicit feedback on EMA study procedures and materials from the target populations for a larger study about binge eating among sexual minority and heterosexual young women, in which data are collected entirely remotely. Methods: Sexual minority (n=12) and heterosexual (n=9) women ages 18-30 who binge ate took part in a pilot EMA study and exit interview and survey. As part of the consent and orientation process, participants reviewed video and written materials describing the study purpose and procedures. Using a smartphone app, for seven consecutive days they completed a survey each morning, 5 random surveys per day, and self-initiated a survey each time they binge ate. Participants then provided feedback on the study via a 1-hour virtual interview and online survey. Interviews were transcribed and reviewed by two coders to identify themes on the acceptability and feasibility of the EMA procedures with a focus on: (I) the training and study description materials; (II) general smartphone app and survey preferences; and (III) specific EMA survey question content and wording. Results: The qualitative and quantitative data converged to suggest participants were able to easily download and use the app to complete surveys and report on binge eating events. Participants provided feedback that was incorporated into revisions on general study procedures, the training video content, and EMA question content for binge eating, identity-related stressors, and appearance-related pressures. No systematic themes in the quantitative or qualitative data emerged to suggest questions were perceived differently by sexual minority and heterosexual young women. Conclusions: These findings provide evidence for the feasibility of conducting a remote EMA study to assess young women's experiences around binge eating. This formative study provides an example of how a mixed methods approach can be used to refine EMA study methods and questions to improve study design.

Recruiting Cisgender Female Couples for Health Disparity-Focused Daily Diary Research: Challenges, Successes, and Lessons Learned.

The underlying mechanisms of sexual minority women's (SMW's) numerous physical and mental health disparities compared to heterosexual women are not well understood. The contribution of relationship factors is particularly understudied; few studies collect data from both same-sex female partners. Further, most research among SMW is cross sectional which limits our understanding of day-to-day experiences of same-sex women's couples. This paper aimed to describe the feasibility of recruiting a large sample of SMW and their female partners for a disparity-focused daily diary study investigating alcohol use and mental health. A firm specializing in sexual minority market research was enlisted to help with recruitment from multiple sources and conducted an initial pre-screening of SMW and their female partners, at least one of whom drank alcohol regularly. A total of 4182 individuals completed the pre-screener, with information for 930 individuals (465 couples) being sent to the research team. From this, 376 individuals (188 couples) completed the study screener, met the inclusion criteria, and were invited to participate. Ultimately, 326 individuals (163 couples) consented and completed baseline. A total of 321 individuals, from 162 couples, began the daily diary portion of the study. Compliance with study procedures was excellent. The use of multiple recruitment sources increased the diversity of the sample. Challenges to recruitment, changes in protocol, and characteristics of the final sample are discussed.

Rationale and Design of an Ecological Momentary Assessment Study Examining Predictors of Binge Eating Among Sexual Minority and Heterosexual Young Women: Protocol for the Health and Experiences in Real Life (HER Life) Study.

BACKGROUND: Previous research has identified health disparities between sexual minority and heterosexual women, including increased rates of obesity and binge eating in sexual minority women. Established predictors of binge eating behavior include negative emotions and sociocultural processes; however, these studies are generally conducted in samples of young women where sexual identity is not known or reported. There is a dearth of research evaluating how sexual minority-specific factors (eg, minority stress and connectedness to the lesbian, gay, bisexual, transgender, and queer community) may affect binge eating in sexual minority women. In addition, no studies have examined these processes in racially diverse samples or considered how intersecting minority identities (eg, Black and sexual minority) may affect eating behaviors. OBJECTIVE: The Health and Experiences in Real Life (HER Life) Project aims to clarify real-world predictors of binge eating in young heterosexual and sexual minority women using ecological momentary assessment. The role of affective, social, and health behavior factors in binge eating will be examined for all women (aim 1), and sexual minority-specific predictors will also be considered for sexual minority women participants (aim 2). Person-level moderators of race, body- and eating-related factors, and sexual minority-specific factors will also be examined to better understand how real-world binge eating predictors may differ for various demographic groups (aim 3). METHODS: Researchers aim to recruit 150 sexual minority and 150 heterosexual women from across the United States, including at least 50 Black women for each group, using web-based recruitment methods. The eligibility criteria include identifying as a woman, being aged between 18 and 30 years, and having had at least two binge eating episodes in the last 2 weeks. Participants must endorse being only or mostly attracted to men (considered heterosexual) or only or mostly attracted to women or having a current or most recent female partner (considered sexual minority). Eligible participants complete an initial web-based baseline survey and then 14 days of ecological momentary assessment involving the completion of a morning and before-bed survey and 5 prompted surveys per day as well as a user-initiated survey after binge eating episodes. The data will be analyzed using a series of multilevel models. RESULTS: Data collection started in February 2021. We have currently enrolled 129 sexual minority women and 146 heterosexual women. Data collection is expected to conclude in fall 2022. CONCLUSIONS: The Health and Experiences in Real Life Project aims to elucidate potential differences between sexual minority and heterosexual women in within-person factors predicting binge eating and inform eating disorder interventions for sexual minority women. The challenges in recruiting sexual minority women, including the determination of eligibility criteria and considerations for remote data collection, are discussed.

A dyadic examination of alcohol use and intimate partner aggression among women in same-sex relationships.

Despite considerable evidence linking alcohol use and intimate partner aggression among mixed-sex couples, scant research has examined this association in same-sex couples using a dyadic framework. The aim of the present study was to examine associations between one's own and their partner's alcohol use (i.e., drinks per week, hazardous alcohol use) and intimate partner aggression (physical, psychological) perpetration while accounting for the interdependence among partners in alcohol use. Participants were 326 women (Mage = 27.57, SD = 3.65) from 163 female-female couples who independently completed measures of drinks per week, hazardous alcohol use, psychological intimate partner aggression victimization and perpetration, and physical intimate partner aggression victimization and perpetration. Actor-partner interdependence structural equation models found that (1) actor drinks per week were positively associated with one's own physical assault perpetration (2) actor hazardous alcohol use was positively associated with one's own physical assault and psychological aggression perpetration and (3) partner drinks per week and hazardous alcohol use were positively associated with actor's psychological aggression perpetration. No other significant effects were detected. Collectively, findings highlight the nuanced relationship between alcohol use and intimate partner aggression among same-sex female couples and suggest that one's own alcohol use is associated with intimate partner psychological and physical aggression perpetration. In contrast, the only partner effect was partner's alcohol use in association with actor's psychological aggression perpetration. These findings differ from prior research with heterosexual couples and underscore the need for future research with same-sex couples rather than attempts to generalize findings across populations.

The role of alcohol demand on daily microaggressions and alcohol use among emerging adult bisexual+ women.

Objective: Bisexual women drink more and have more alcohol consequences than heterosexual and lesbian women. This higher risk may in part be attributable to sexual orientation microaggressions. Drinking to cope motivations and alcohol demand may influence the association between microaggressions and alcohol use. The present study used a daily diary design to examine the association between microaggressions and same-day alcohol use (yes/no, quantity) and consequences, and if drinking to cope and alcohol demand moderate this association among bisexual+ (i.e., bi+) women. Method: Participants were 103 emerging adult bi+ women who completed a baseline assessment, including an alcohol purchase task to measure alcohol demand. Subsequently, participants reported their experiences of microaggressions, alcohol use, and alcohol consequences for 28 days. Multilevel model analyses were conducted. Results: Microaggressions were associated with a higher likelihood to drink and greater same-day alcohol use and consequences. The association between microaggressions and alcohol quantity was stronger for those who had a lower price associated with the highest expenditure (lower P max). For those who would stop drinking at lower price values (lower breakpoint), reported spending less overall on alcohol (lower O max), and had lower P max values, microaggressions were associated with more consequences. For those with higher breakpoint, O max, and P max microaggressions were not associated with consequences. Conclusions: Microaggressions may have a deleterious impact on alcohol use and consequences for bi+ women, particularly for those with lower alcohol demand. Clinicians should encourage bi+ clients to consider how microaggressions influence their drinking and support clients to engage in positive coping skills.

Associations between body dissatisfaction and relationship functioning among same-sex female couples: An actor-partner interdependence model.

Nearly all past research about body dissatisfaction and romantic relationship factors is among heterosexual couples; little is known about these associations in sexual minority couples. The present study aimed to fill gaps in the current literature by using actor-partner interdependence models (APIMs) to examine dyadic patterns of association between body dissatisfaction and different aspects of relationship functioning among same-sex female couples. Participants were 163 same-sex female romantic dyads (326 women) between the ages of 18-35 years who completed measures of body dissatisfaction and relationship factors. Results from significance testing of actor and partner effects indicated higher levels of women's own body dissatisfaction were associated with lower levels of their own, but not their partner's, relationship satisfaction, closeness, sexual satisfaction, and intimacy/connectedness. Significance testing alone indicated that the association between one's own body dissatisfaction and their partner's relationship satisfaction was not significant. However, dyadic pattern testing identified a partner pattern for this effect, which suggests that the association between one's own body dissatisfaction and one's own relationship satisfaction is similar in magnitude and direction as that between an individuals' own body dissatisfaction and their partner's relationship satisfaction. In this study, women's own body dissatisfaction was found to be negatively associated with their own relationship functioning, which is consistent with findings of women in male-female couples. Thus, these findings highlight the important role that body dissatisfaction plays in women's relationship experiences. More research is needed to better understand potential cross-partner effects of body dissatisfaction and relationship factors in same-sex female couples.

Psychometric analysis and validity of the Daily Sexual Minority Stressors Scale among young adult same-sex female couples.

Sexual minority women experience greater health disparities relative to heterosexual women, which is thought to be due to unique stressors related to their sexual identities. Daily diary or momentary assessments may provide a more nuanced approach to understanding how sexual minority stressors relate to health behaviors than cross-sectional studies provide. To date, there is no validated measure to examine daily sexual minority stressors. A recent pilot study developed a brief (8-item) measure for assessing sexual minority stressors in self-identified lesbian or mostly lesbian women (Heron et al., 2018). Although an optimal number of items were generated to best capture the daily experiences of lesbian women, psychometric examination and validation of this new measure is necessary. Using multilevel confirmatory factor analysis among a fully scaled sample of sexual minority women, the present study established that the Daily Sexual Minority Stressors Scale has good model fit as a unidimensional measure (i.e., one factor at each level of analysis). Intraclass correlations indicate the majority of variation (57%) is within person. Additionally, we established convergent and discriminant validity using similar measures (single-item assessment, general stressors, negative affect, history of discrimination, and heterosexism). Finally, criterion validity was supported. At the daily level, experiencing daily sexual minority stressors was associated with a significantly greater likelihood of drinking alcohol that day. Experiencing more daily sexual minority stressors during the study period was significantly associated with a history of harassment and discrimination, victimization, isolation, vigilance, and also with acceptance concerns, difficult processes, and internalized homonegativity.

Evaluating study procedure training methods for a remote daily diary study of sexual minority women.

BACKGROUND: Ecological momentary assessment (EMA) methods can be used to remotely assess physical and mental health in daily life for hard-to-reach, marginalized, and geographically dispersed populations in the U.S., such as sexual minority women (e.g., lesbian, bisexual). However, EMA studies are often complex, and engaging participants from afar can be a challenge. This study experimentally examined whether adding videos to written recruitment materials would improve consent rates, reduce dropout rates, and improve survey completion rates for an online daily diary study. METHODS: As part of a 2-week study of same-sex female couples' health, 376 women ages 18-35 were recruited from across the U.S. using a market research firm. Couples were randomized to an introductory information condition (written + video materials or written-only materials) prior to informed consent. RESULTS: Overall, 97.1% of eligible women reviewed introductory materials and of these 96.7% consented; consent rates did not differ by condition (written + video: 97.1%, written-only: 97.1%). Dropout rates were low (5.4%) and survey completion rates were high (90.4% of surveys completed); there were no group differences for study dropout (written + video: 3.6%, written-only: 7.0%) or survey completion (written + video: 92.5%, written-only: 88.4%). Data from women randomized to receive videos indicated more than half (53.3%) did not watch any of the five videos in full. However, among those who viewed the videos, time spent watching videos, watching more videos in full, and watching at least one video in full were each positive associated with survey completion rates. CONCLUSIONS: In summary, we had high consent rates, low dropout rates, and high survey completion rates regardless of video instructions. Although sexual minority women can be hard to reach, our potential participants appeared highly motivated to take part in research, and thus video recruitment materials were not necessary to improve participation. Future experimental research to maximize EMA study design and implementation could be important for populations less inclined to participate in EMA studies, or who are less familiar with research.

Minority stress and alcohol use in sexual minority women's daily lives.

Sexual minority women (i.e., women who identify as lesbian, bisexual, or other non-heterosexual orientations) report more hazardous drinking compared to heterosexual women. Sexual minority stress (SMS), or experiences related to sexual orientation-based discrimination and marginalization, have been implicated as contributing to these disparities. The association between sexual minority stress and alcohol use has been supported in cross-sectional, and to a limited extent, longitudinal studies. Few studies, however, have examined associations between SMS and alcohol use in sexual minority women's daily lives. Young sexual minority women (age 18-35; N = 321) were recruited to participate in a 14-day daily diary study in which they reported each morning on their SMS and alcohol use (drinking or not; drinking quantity; alcohol consequences) from the previous day. SMS was operationalized in four ways (global negative SMS experiences, specific SMS events, concealment of identity, discrimination). Results from concurrent multilevel models revealed that on days when sexual minority women experienced more global negative SMS, any specific SMS event, or discrimination, they were more likely to drink. Further, prospective models indicated that participants drank more and were more likely to report binge drinking on the day after they experienced at least one SMS event. These findings extend prior research by demonstrating that the association between SMS and alcohol use extends to the daily level of analysis among sexual minority women. Understanding the connection between SMS and alcohol use among sexual minority women is imperative to developing culturally tailored interventions to improve the health and well-being of this at-risk group.

Sexual Minority Stress and Social Support Explain the Association between Sexual Identity with Physical and Mental Health Problems among Young Lesbian and Bisexual Women.

Bisexual women report more physical and psychological health problems than lesbian women do, which may be attributed to greater sexual minority stress and less social support. However, many studies combine lesbian and bisexual women into a single group. The current study examined if sexual minority stress and social support mediated the association between women's sexual identity (lesbian or bisexual) and health-related outcomes. A total of 650 U.S. young adult lesbian (n = 227) and bisexual (n = 423) women completed an online survey about sexual minority stress, social support, and physical and mental health problems. Bisexual women reported more physical and mental health problems. A sequential mediation model showed that bisexual women reported greater sexual minority stress than lesbian women, which in turn was associated with less social support, which was associated with more physical and mental health problems. Greater sexual minority stress and lower social support may help explain why bisexual women report more health-related problems than lesbian women. The results of the present study support the importance of examining risk and protective factors for health problems separately for lesbian and bisexual women. Health-related intervention programs that target sexual minority women may need to be tailored differently for lesbian and bisexual women.

Health Disparities Among Exclusively Lesbian, Mostly Lesbian, and Bisexual Young Women.

Purpose: Health disparities have been identified between groups of diverse young sexual minority women (SMW) and heterosexual women. This approach may generate sufficient group sizes for statistical analyses but obscures important differences. Moreover, some young women may not identify as "lesbian" or "bisexual" but somewhere in between. This study examined health and sexual minority identity-specific outcomes among three groups of SMW-women who identify as "exclusively lesbian," "mostly lesbian," and "bisexual." Methods: Participants were 990 young (18-30 years old) SMW (exclusively lesbian: n = 305, mostly lesbian: n = 133, bisexual: n = 552) who completed an online survey, including information about mental and physical health symptoms, hazardous drinking, and identity uncertainty. Those who reported alcohol use in the past 30 days responded to questions about their alcohol use and alcohol-related negative consequences. Results: Controlling for demographic differences, health outcomes varied significantly by identity. Mostly lesbian and bisexual women reported the most depression, anxiety, and physical health symptoms; mostly lesbian women reported the highest levels of hazardous drinking. Among those who reported drinking, mostly lesbian women drank the most frequently and reported the most alcohol-related consequences. Mostly lesbian women reported the most identity uncertainty. Conclusion: Mostly lesbian women were similar to bisexual women on several health outcomes. They appear unique, however, in drinking behavior and identity uncertainty. Collapsing across identities in health research may affect outcomes.

Clustered Patterns of Behavioral and Health-Related Variables Among Young Lesbian Women.

Lesbian women are at increased risk for a variety of mental and physical health problems compared to heterosexual women. In order to inform treatment and prevention, the purpose of this study was to examine behavioral and health-related patterns among lesbian women and elucidate how these patterns are associated with general discrimination, sexual minority stress, affect, and social support. A sample of self-identified lesbian women (N = 436) completed an online survey from August 2014-March 2015. A latent profile analysis was conducted using measures of body mass index, hazardous alcohol use, binge eating, eating disorder risk, and exercise as indicators. A 5-class solution best fit the data and included two healthy groups: (a) low health risk, moderate exercise (54%), (b) low health risk + high exercise (22%); and three unhealthy risk groups: (c) obese + binge eating (14%); (d) disordered eating + hazardous alcohol use (5%); (e) disordered eating + high exercise (5%). The three unhealthy classes generally reported more general discrimination, sexual minority stress, social anxiety, negative affect, and lower social support compared to the healthy classes. These findings show that behavioral and health-related variables cluster together in several distinct patterns among lesbian women. In addition, general discrimination and sexual minority stress and associated psychosocial functioning may be related to these maladaptive behavioral and health-related patterns and may be important to consider in behavioral interventions.

Rationale and Design of a Remote Web-Based Daily Diary Study Examining Sexual Minority Stress, Relationship Factors, and Alcohol Use in Same-Sex Female Couples Across the United States: Study Protocol of Project Relate.

BACKGROUND: The Healthy People 2020 initiative aims to reduce health disparities, including alcohol use, among sexual minority women (SMW; eg, lesbian, bisexual, queer, and pansexual). Compared with heterosexual women, SMW engage in more hazardous drinking and report more alcohol-related problems. Sexual minority stress (ie, the unique experiences associated with stigmatization and marginalization) has been associated with alcohol use among SMW. Among heterosexuals, relationship factors (eg, partner violence and drinking apart vs together) have also been associated with alcohol use. Negative affect has also been identified as a contributor to alcohol use. To date, most studies examining alcohol use among SMW have used cross-sectional or longitudinal designs. OBJECTIVE: Project Relate was designed to increase our understanding of alcohol use among young SMW who are at risk for alcohol problems. The primary objectives of this study are to identify daily factors, as well as potential person-level risk and protective factors, which may contribute to alcohol use in SMW. Secondary objectives include examining other physical and mental concerns in this sample (eg, other substance use, eating, physical activity, and stress). METHODS: Both partners of a female same-sex couple (aged 18-35 years; n=150 couples) are being enrolled in the study following preliminary screening by a market research firm that specializes in recruiting sexual minority individuals. Web-based surveys are being used to collect information about the primary constructs of interest (daily experiences of alcohol use, sexual minority stress, relationship interactions, and mood) as well as secondary measures of other physical and mental health constructs. Data are collected entirely remotely from women across the United States. Each member of eligible couples completes a baseline survey and then 14 days of daily surveys each morning. Data will be analyzed using multilevel structural equation modeling. RESULTS: To date, 208 women (ie, 104 couples) were successfully screened and enrolled into the study. In total, 164 women have completed the 14-day daily protocol. Compliance with completing the daily diaries has been excellent, with participants on average completing 92% of the daily diaries. Data collection will be completed in fall 2018, with results published as early as 2019 or 2020. CONCLUSIONS: Project Relate is designed to increase our understanding of between- and within-person processes underlying hazardous drinking in understudied, at-risk SMW. The study includes a remote daily diary methodology to provide insight into variables that may be associated with daily hazardous alcohol use. Before the development of programs that address hazardous alcohol use among young SMW, there is a need for better understanding of individual and dyadic variables that contribute to risk in this population. The unique challenges of recruiting and enrolling SMW from across the United States in a daily diary study are discussed. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/11718.

Measuring Sexual Minority Stressors in Lesbian Women's Daily Lives: Initial Scale Development.

Lesbian women face unique sexual minority stressors (SMS) due to their stigmatized and marginalized status in society. Existing studies of SMS are primarily cross-sectional and use global measures of SMS. The goal of the present study was to develop a brief daily measure of SMS for use in daily diary or ecological momentary assessment (EMA) studies. Existing retrospective measures of SMS were reviewed, resulting in an initial pool of 29 items. Thirty-eight lesbian women (Mage=24.3 years, range: 19-30 years) completed a daily web-based survey including the SMS items for 12 days. Two response scales were tested; participants were randomized to receive a 3-point (for brevity) or 7-point (for precision) scale for the first 6 days and the other response scale for the remaining 6 days to counterbalance order. Findings suggest the 7-point scale was optimal because it provided greater variability. To reduce scale length, item correlations were examined to identify clusters and one item was retained from each cluster, reducing the scale to 18 items. Then, using HLM, null models with each item as the outcome were conducted to examine level-1 and level-2 variances; 8-, 10-, 12-, and 18-item scales were compared to identify the ideal number of items. The 8-item scale had the highest Cronbach's alpha (.85) and the smallest intraclass correlation (ICC; .13), suggesting these 8 items are optimal for capturing within-person variability in young lesbian women's daily SMS experiences. As researchers are increasingly interested in using EMA methods, this 8-item measure can assess SMS in lesbian women's everyday lives.

Discrepant Drinking and Partner Violence Perpetration Over Time in Lesbians' Relationships.

Discrepant drinking (i.e., differences in alcohol use) and perpetration of intimate partner violence in same-sex female couples were examined. Self-identified lesbian participants were recruited from market research firms and reported on their own and their partner's alcohol use and their own perpetration of psychological aggression and physical violence at baseline, then 6 and 12 months later. Cross-lagged panel analyses revealed that discrepant drinking predicted participants' subsequent perpetration of psychological aggression but not physical violence. Both psychological aggression and physical aggression predicted subsequent discrepant drinking. Consistent with findings in heterosexual couples, differences in alcohol use appear to be a risk factor for relationship aggression.

Independent and interactive associations of negative affect, restraint, and impulsivity in relation to binge eating among women.

There is growing recognition that impulsivity may serve as an underlying risk factor for binge eating. In addition, the association of impulsivity with binge eating may be moderated by other affective and cognitive risk factors. This study examined independent and interactive associations of negative affect, dietary restraint, and facets of impulsivity with binge eating. A diverse sample of 566 undergraduate women completed online questionnaires of study variables. Results revealed a three-way interaction of negative affect, dietary restraint, and attentional impulsivity in relation to binge eating. Women who were high on each of these three variables reported the greatest levels of binge eating. In addition, a two-way interaction was found for negative affect and nonplanning impulsivity in relation to binge eating, such that nonplanning impulsivity strengthened the association between negative affect and binge eating. Attentional and nonplanning facets of impulsivity may function as an underlying trait-level risk factor interacts with affective and/or cognitive risk (e.g., negative affect, dietary restraint) factors to predict elevated binge eating.

Sexual Coercion, Drinking to Cope Motives, and Alcohol-Related Consequences among Self-Identified Bisexual Women.

BACKGROUND: Given higher sexual victimization and greater alcohol use among bisexual women, a critical public health challenge is to understand within-group variation that may heighten or explain these associations in bisexual women. OBJECTIVES: The present study tested a moderated-mediation model in which sexual coercion was hypothesized to be associated with alcohol-related consequences via drinking to cope motives in self-identified bisexual women who reported at least occasional binge drinking. Negative affect was hypothesized to moderate the sexual coercion-drinking to cope motives association. METHODS: Participants were a community sample of 107 self-identified bisexual women (age M = 20.97, SD = 2.11) who completed an online survey and reported at least one binge drinking episode as well as engaging in sexual activity in the past 30 days. RESULTS: Of these participants, 57 (53.3%) reported one or more experiences of sexual coercion in the past 30 days. Sexual coercion was associated with negative alcohol-related consequences via drinking to cope motives. Negative affect moderated the association between sexual coercion and drinking to cope motives such that the association was stronger among women with greater negative affect. Conclusions/Importance: Methods of addressing vulnerability to sexual coercion and educating young bisexual women about the association between sexual coercion and potentially problematic affective coping through alcohol use are needed.

Social Factors Linking Stigma-Related Stress with Alcohol Use among Lesbians.

A conceptual model linking stigma-related stress and lesbian women's alcohol use and related problems via social factors (i.e., social constraints and social isolation), depressive symptoms, and negative reinforcement drinking motives (i.e., coping and conformity) was tested. Self-identified lesbian women (N = 1048), age 18-35 years in the United States completed an online survey of discrimination, stigma consciousness, social isolation, social constraints, depressive symptoms, drinking motives, alcohol use and related problems. The hypothesized path model showed excellent model fit. The predicted pathway of stigma-related stressors to alcohol outcomes via social factors, depressive symptoms, and coping/conformity motives was largely supported. Results highlight the importance of social factors in linking stigma-related stress to alcohol use and related problems among lesbians. Understanding the underlying social mechanisms connecting stigma to negative health outcomes may help inform intervention efforts to reduce alcohol use and related problems among lesbians and associated health disparities.
