Mediation of Parental Aggravation in the Association Between ADHD Severity and Electronic Media Use: A National Survey of Children's Health Study.

OBJECTIVE: To determine whether the association between ADHD severity and electronic media use was mediated by parental aggravation. METHODS: This was a retrospective analysis from the 2016 to 2017 National Survey of Children's Health (NSCH) involving children ages of 3 to 17 years with parent-reported ADHD (n = 5,930). Path analyses were used to model the relationships between ADHD severity with parental aggravation (PA) as a mediator, and electronic device (ED) and television (TV) use as outcomes, controlling for covariates. RESULTS: Parental aggravation mediated the relationship between ADHD severity and ED use and TV use (indirect effects: ß = .02, p < .001; ß = .01, p = .004). When stratified by age, the mediation effect between ADHD and ED use remained significant for adolescents and school-age children, and mediation between ADHD and TV use remained significant only for adolescents. CONCLUSION: These findings suggest a need to develop targeted interventions to address PA and manage excessive electronic media use in children with moderate/severe ADHD.

Hyperactivity and Impulsivity Symptoms Mediate the Association Between Adverse Childhood Experiences and Reading Achievement: A LONGSCAN Cohort Study.

Adverse Childhood Experiences (ACEs) include various childhood stressors that can negatively impact the health and well-being of children. ACEs are associated with poor academic achievement. Attention is strongly associated with academic achievement, and there is a graded relationship between ACEs exposure and subsequent development of parent-reported ADHD; however, it is unclear whether ADHD symptoms mediate the relationship between ACEs and academic achievement. This study tested a model of mediation by ADHD symptoms between ACEs and academic achievement (measured by reading score). This retrospective cohort analysis utilized data from the Longitudinal Study on Child Abuse and Neglect (LONGSCAN), a data consortium exploring the impact of child maltreatment (n = 494). There were relatively even numbers of male and female child participants, and the majority of caregivers were either non-Hispanic White or Black. Path analyses were modeled for ACEs as a sum score and separately for individual ACE exposures, with number of symptoms of Inattention (IN) and Hyperactivity/Impulsivity (H/I) as mediators, and academic achievement as the outcome, adjusting for covariates. ACEs were highly prevalent in this sample (M = 5.10, SD = 1.90). After retaining significant covariates, significant direct associations (P < .05) were seen between ACE sum score and IN (ß = .14) and H/I (ß = .21), and between H/I and reading score (ß=-.14). A higher ACE score was associated with lower reading scores through variation in H/I, but not IN. H/I mediated the relationship between ACEs and reading score in this high-risk population, providing new insight into relationships between ACEs and academic achievement, which can inform interventions.

Exploring Racial and Ethnic Differences in Parent-Reported Strengths in Children with Autism Spectrum Disorder.

BACKGROUND: Several studies have demonstrated racial/ethnic differences in parental concerns in children with autism spectrum disorder (ASD). However, no studies have investigated racial/ethnic differences in parent-reported strengths. The purpose of this study was to explore racial/ethnic differences in parent-reported strengths in children with ASD. DESIGN AND METHODS: This was a retrospective cross-sectional study investigating the relationship between parent-reported strengths and race/ethnicity at the time of an ASD diagnosis. Parent-reported strengths were qualitatively clustered into themes, and theme frequencies were quantitatively examined for relationships to race/ethnicity. RESULTS: Parents of Caucasian children reported a mean of 5.00 (SD = 2.17) total strengths compared to 3.75 (SD = 2.32) among Hispanic/Latinx children, 3.36 (SD = 1.43) among Asian/PI children, and 3.91 (SD = 2.05) among children from other races/ethnicities. Bivariate linear regression analyses indicated that Asian/PI, Hispanic, and other child race/ethnicity, compared to Caucasian child race/ethnicity, were associated with significantly fewer parent-reported total strengths. Asian/PI and Hispanic child race/ethnicity were associated with significantly fewer personality strengths, while maternal education was associated with a greater number of personality strengths. CONCLUSION: This study found racial and ethnic differences in parent-reported strengths in children with ASD. Further, higher levels of maternal education influenced total, personality, and behavioral strengths. Receipt of a greater number of child services was also associated with a greater number of behavioral strengths.

Development and Validation of the Military Minority Stress Scale.

Despite affecting nearly 3% of active-duty service members, little is known about how LGBT-related stress experiences may relate to health outcomes. Thus, the present study sought to create a Military Minority Stress Scale and assess its initial reliability and construct validity in a cross-sectional study of active-duty LGBT service members (N = 248). Associations between 47 candidate items and health outcomes of interest were analyzed to retain those with substantial betas. Item response theory analyzes, reliability testing, invariance testing, and exploratory factor analysis were performed. Construct validity of the final measure was assessed through associations between the sum score of the final measure and the health outcomes. The final 13-item measure demonstrated an excellent reliability (ω = 0.95). Bivariate linear regressions showed significant associations between the sum score of the measure and overall health (ß = -0.26, p < 0.001), overall mental health (ß = -0.34, p < 0.001), physical health (ß = 0.45, p < 0.001), life satisfaction (ß = -0.24, p < 0.001), anxiety (ß = 0.34, p < 0.001), depressive symptoms (ß = 0.37, p < 0.001), suicidality (ß = 0.26, p < 0.001), and PTSD (ß = 0.42, p < 0.001), respectively. This study provides the first evidence that minority stressors in the military setting can be operationalized and measured. They appear to have a role in the health of LGBT service members and may explain the continued health disparities experienced by this population. Little is known regarding the experiences of LGBT active-duty service members, including experiences of discrimination. Understanding these experiences and their associated health outcomes during military service may therefore help and guide further etiological studies and intervention development.

Nominal Versus Realized Costs of Recruiting and Retaining a National Sample of Sexual Minority Adolescents in the United States: Longitudinal Study.

BACKGROUND: Web-based recruitment for research studies is becoming increasingly popular and necessary. When compared with the traditional methods of recruitment, these methods may enable researchers to reach more diverse participants in less time. Social media use is highly prevalent among adolescents, and the unique context of social media may be particularly important for the recruitment of sexual minority young people who would not be captured by traditional methods. OBJECTIVE: This paper described the details of a national web-based study recruitment approach aimed at sexual minority adolescents across the United States, focusing on important details of this relatively novel approach, including cost, time efficiency, and retention outcomes. METHODS: This study recruited sexual minority adolescents aged 14-17 years living in the United States through targeted advertisements on Facebook, Instagram, and YouTube and through respondent-driven sampling (RDS). Potential participants completed eligibility screening surveys and were automatically directed to a baseline survey if they were eligible. After baseline survey completion, additional data checks were implemented, and the remaining participants were contacted for recruitment into a longitudinal study (surveys every 6 months for 3 years). RESULTS: Recruitment lasted 44 weeks, and 9843 participants accessed the initial screening survey, with 2732 (27.76%) meeting the eligibility criteria and completing the baseline survey. Of those, 2558 (93.63%) were determined to have provided nonfraudulent, usable study data and 1076 (39.39%) subsequently enrolled in the longitudinal study. Of the baseline sample, 79.05% (2022/2558) was recruited through Facebook and Instagram, 3.05% (78/2558) through YouTube, and 17.9% (458/2558) through RDS. The average cost of recruiting a participant into the study was US $12.98, but the recruitment cost varied by method or platform, with a realized cost of US $13 per participant on Facebook and Instagram, US $24 on YouTube, and US $10 through RDS. Participant differences (sex assigned at birth, race and ethnicity, sexual orientation, region, and urbanicity) were identified between platforms and methods both in terms of overall number of participants and cost per participant. Facebook and Instagram were the most time efficient (approximately 15 days to recruit 100 participants), whereas RDS was the least time efficient (approximately 70 days to recruit 100 participants). Participants recruited through YouTube were the most likely to be longitudinally retained, followed by Facebook and Instagram, and then RDS. CONCLUSIONS: Large differences exist in study recruitment cost and efficiency when using social media and RDS. Demographic, region, and urbanicity differences in recruitment methods highlight the need for attention to demographic diversity when planning and implementing recruitment across platforms. Finally, it is more cost-effective to retain than recruit samples, and this study provided evidence that with thorough screening and data quality practices, social media recruitment can result in diverse, highly involved study populations.

Age Differences in the Associations Between Outness and Suicidality Among LGBTQ+ Youth.

OBJECTIVE: Lesbian, gay, bisexual, transgender, and queer (LGBTQ+) youth are at increased risk for suicidality compared to their heterosexual and cisgender peers, and outness (the extent to which an individual is open about their LGBTQ+ identity to others) is an important correlate of suicidality. However, previous research has led to mixed findings regarding whether outness functions as a risk or protective factor for suicidality, and the available evidence suggests that age may play an important role. As such, the goal of the current study was to examine whether the associations between outness and suicidality differed between LGBTQ+ adolescents (ages 12-17) and emerging adults (ages 18-24). METHOD: The analytic sample included 475 LGBTQ+ youth who completed an online survey after contacting a national, LGBTQ+ crisis service provider. RESULTS: Results indicated that age significantly moderated the association between outness and suicidal ideation, such that greater outness was significantly associated with greater suicidal ideation for adolescents, but not for emerging adults. In contrast, age did not significantly moderate the associations between outness and likelihood of a past suicide attempt or perceived likelihood of a future suicide attempt. However, the main effect of outness was significant in both models, such that greater outness was significantly associated with a greater likelihood of a past suicide attempt and a greater perceived likelihood of a future suicide attempt. CONCLUSIONS: These findings suggest that the associations between outness and suicidality among LGBTQ+ youth may depend on age as well as the dimension of suicidality (ideation versus attempt). HighlightsBeing more open about one's LGBTQ+ identity may confer risk for suicidality.The influence of outness on suicidal ideation may be strongest during adolescence.There is a need for LGBTQ+ affirming policies and laws to reduce suicidality.

Adolescent stress experiences over time study (ASETS) protocol: design and methods of a prospective longitudinal study of sexual minority adolescents in the USA.

INTRODUCTION: Sexual minority adolescents (SMA) report higher rates of anxiety, self-harm, depression and suicide than heterosexual peers. These disparities appear to persist into adulthood and may worsen for certain subgroups, yet the mechanisms that drive these concerns remain poorly understood. Minority stress theory, the predominant model for understanding these disparities, posits that poorer outcomes are due to the stress of living in a violently homophobic and discriminatory culture. Although numerous studies report associations between minority stress and behavioural health in adolescence, no study has comprehensively examined how minority stress may change throughout the course of adolescence, nor how stress trajectories may predict health outcomes during this critical developmental period. METHODS AND ANALYSIS: Between 15 May 2018 and 1 April 2019, we recruited a US national sample of diverse SMA (n=2558) age 14-17 through social media and respondent-driven sampling strategies. A subset of participants (n=1076) enrolled in the longitudinal component and will be followed each 6 months until 1 July 2022. Primary outcomes include symptoms of depression, anxiety and post-traumatic stress disorder; suicidality and self-harm and substance use. The key predictor is minority stress, operationalised as the Sexual Minority Adolescent Stress Inventory. We will use parallel cohort-sequential latent growth curve models to test study hypotheses within a developmental framework. ETHICS AND DISSEMINATION: All participants provided assent to participate, and longitudinal participants provided informed consent at the first follow-up survey after reaching age 18. All study procedures were reviewed and approved by the University of Southern California Social-Behavioral Institutional Review Board, including a waiver of parental permission given the potential for harm due to unintentional 'outing' to a parent during the consent process. The final anonymous data set will be available on request, and research findings will be disseminated through academic channels and products tailored for the lay community.

Health and Service-related Impact of Sexual and Stalking Victimization During United States Military Service on LGBT Service Members.

Prior research among military personnel has indicated that sexual harassment, stalking, and sexual assault during military service are related to negative health sequelae. However, research specific to LGBT U.S. service members is limited. The current study aimed to explore the health, service utilization, and service-related impact of stalking and sexual victimization experiences in a sample of active-duty LGBT U.S. service members (N = 248). Respondent-driven sampling was used to recruit study participants. U.S. service members were eligible to participate if they were 18 years or older and active-duty members of the U.S. Army, U.S. Navy, U.S. Marine Corps, or U.S. Air Force. This study included a sizeable portion of transgender service members (N = 58, 23.4%). Sociodemographic characteristics, characteristics of military service, health, and sexual and stalking victimization in the military were assessed. Regression was used to examine relationships between health and service outcomes and sexual and stalking victimization during military service. Final adjusted models showed that experiencing multiple forms of victimization in the military increased the odds of visiting a mental health clinician and having elevated somatic symptoms, posttraumatic stress disorder symptomatology, anxiety, and suicidality. Sexual and stalking victimization during U.S. military service was statistically significantly related to the mental and physical health of LGBT U.S. service members. Interventions to reduce victimization experiences and support LGBT U.S. service members who experience these types of violence are indicated. Research that examines the role of LGBT individuals' experiences and organizational and peer factors, including social support, leadership characteristics, and institutional policies in the United States military is needed.

Characteristics and Perceptions of Sexual and Gender Minority Youth Who Utilized a National Sexual and Gender Minority-Focused Crisis Service.

Background: Sexual and gender minority youth (SGMY) have heightened risk of suicidality; yet, we know little about their experiences when utilizing crisis services. Aims: The purpose of this study was to understand the characteristics and experiences of SGMY when in contact with SGMY-specific suicide crisis services. Method: Data were from 592 SGMY who contacted the most widely utilized national US SGMY-specific crisis services provider. Results: High rates of suicide ideation (65.2%) and attempts (31.9%) were documented, with gender minority youth endorsing higher rates of suicide attempts. Participants contacted the center by phone (57.8%) more than by online chat/text (42.2%). Participants reported discussing their sexual orientation (60.6%), gender identity (43.8%), and identity disclosure stress (56.6%) with counselors. Participants rated the crisis service as helpful. The counselors were perceived as warm, compassionate, and knowledgeable about common concerns for SGMY and they were likely to contact the crisis center again. Participants reported using chat/text over phone because it provided them with more confidentiality and privacy; however, phone contacts were rated more positively than text/chat. Limitations: The sample was predominately White and was not representative of the broader population of SGMY, limiting the generalizability of the results. Conclusion: SGMY reported positive experiences with a national SGMY-specific crisis service. The findings highlight the critical need for and utility of SGMY-specific suicide prevention crisis services.

Reducing behavioral health symptoms by addressing minority stressors in LGBTQ adolescents: a randomized controlled trial of Proud & Empowered.

BACKGROUND: Minority stress may lead to poorer mental health for sexual and gender minority adolescents, yet no interventions have been tested through an RCT to address these concerns. METHODS: We report on an RCT of an intervention-Proud & Empowered-with four high schools. Measures assess the intervention's impact on mental health symptoms. RESULTS: Compared to the control, participants in the treatment condition reported significant differences in minority stress, anxiety, and depressive symptoms. Moderation analyses showed that the intervention significantly moderated the relationship between minority stress and PTSD (b = -1.28, p = .032), depression (b = -0.79, p = .023), and suicidality (b = 0.14, p = .012) symptoms; those in the intervention condition had mitigated relationships between measures of stress and health outcomes compared to those in the control condition. CONCLUSIONS: Results suggest that Proud & Empowered help reduce mental health symptoms and exposure to minority stressors and build coping strategies. TRIAL REGISTRATION: The intervention was registered on clinicaltrials.gov on August 1, 2019 under Trial # NCT04041414 .

Confirming the Reliability and Validity of the Sexual Minority Adolescent Stress Inventory in a National Sample of Sexual Minority Adolescents.

Objective: Sexual minority adolescents (SMA) experience numerous behavioral health disparities, including depression, anxiety, substance use, non-suicidal self-injury, and suicidality. The primary framework to understand these disparities is minority stress theory, which frames this disproportionate burden as the result of discrimination, violence, and victimization in a homophobic culture. Empirical examinations of minority stress among SMA have been limited by lack of diverse samples or validated measures. This study engaged a national community sample of SMA to confirm reliability and validity of the Sexual Minority Adolescent Stress Inventory (SMASI). Method: A national sample of 2,310 SMA aged 14-17 was recruited in the United States through a hybrid social media and respondent-driven sampling approach. Item response theory and confirmatory factor analysis established the psychometric properties of the SMASI in this sample; minority stress was modeled as a latent variable in several regression models to verify criterion and divergent validity. Results: In this national sample (M age = 15.9; 64% female and 60% White), the factor structure of the SMASI and its 11 subscales was confirmed and shown to be invariant by demographic characteristics. Minority stress as measured by the SMASI was significantly associated with all mental and behavioral health outcomes. Conclusions: This study provides evidence that SMASI is a reliable, valid, and important tool for better understanding minority stress and subsequent health and mental health consequences among SMA.

Risk Factors for Parenting Stress in Parents of Children Treated with Laser Surgery for Twin-Twin Transfusion Syndrome 2 Years Postpartum.

OBJECTIVE: Twin-twin transfusion syndrome (TTTS) is a rare but serious condition that can occur in monochorionic and diamniotic twin pregnancies. Research indicates almost half of postpartum mothers with TTTS may have clinically significant levels of stress. However, no studies have measured the levels of parenting stress at 2 years postpartum, and little research has been conducted on sources of stress. STUDY DESIGN: A prospective cohort study was conducted. Data were collected from parents whose children were treated with laser ablation in utero and were 2 years old at the time of screening. The Parenting Stress Index - Short Form (PSI-SF) and its three subscales were used to collect data. Descriptive, bivariate, and multivariate analyses were conducted to determine significant predictors associated with each outcome. RESULTS: A total of 99 children from 56 families were enrolled. Unmarried status (B = -22.8; p = 0.039) and lower maternal educational level (B = -7.8; p = 0.01) were both significantly associated with higher PSI-SF total score. CONCLUSION: Subgroups of parents whose pregnancy required laser surgery for TTTS may continue to have clinically significant levels of stress at 2 years postpartum. It is important the health care team is aware of this and the sociodemographic risk factors to provide appropriate support for families.

Sexual Minority Stress, Mental Health Symptoms, and Suicidality among LGBTQ Youth Accessing Crisis Services.

Sexual and gender minority youth are at elevated risk for suicide. Studies have separately established the relation between minority stress and mental health symptoms, as well as minority stress and suicidality. However, no known research has simultaneously examined different mental health mechanisms whereby minority stress may be associated with different suicidal experiences (e.g., suicidal ideation, suicide attempts). The present study used data from a national sample of 572 sexual and gender minority youth aged 12 to 24 (mean age = 17.59; SD = 3.13) recruited from an LGBTQ youth-focused suicide crisis prevention provider. Nearly one-third of the sample (30.2%) identified as transgender, genderqueer, or questioning. Nearly one quarter of the sample (24.3%) identified as gay, 17.1% as pansexual, 16.8% as bisexual, and 15.2% as lesbian. Structural equation modeling was used for mediation analyses to explain suicidal ideation and suicide attempts. Serial mediation models were determined to be the best fit for both suicide-related outcomes. Minority stress was associated with depressive and PTSD symptoms, which were linked with suicidal ideation and attempt through hopelessness. The findings supported the hypotheses that minority stress would be associated with suicidality not just directly, but also indirectly through multiple mental health symptom pathways.

Experiences of Sexual Harassment, Stalking, and Sexual Assault During Military Service Among LGBT and Non-LGBT Service Members.

Sexual victimization, including sexual harassment and assault, remains a persistent problem in the U.S. military. Service members identifying as lesbian, gay, bisexual, or transgender (LGBT) may face enhanced risk, but existing research is limited. We examined experiences of sexual harassment, stalking, and sexual assault victimization during service in a sample of LGBT and non-LGBT active duty service members. Service members who identified as LGBT (n = 227 LGB, n = 56 transgender) or non-LGBT (n = 276) were recruited using respondent-driven sampling for an online survey. Logistic regression models examined the correlates of sexual and stalking victimization. Victimization was common among LGBT service members, including sexual harassment (80.7% LGB, 83.9% transgender), stalking (38.6% LGB, 30.4% transgender), and sexual assault (25.7% LGB, 30.4% transgender). In multivariable models, LGB identity remained a significant predictor of sexual harassment, OR = 4.14, 95% CI [2.21, 7.78]; stalking, OR = 1.98, 95% CI [1.27, 3.11]; and assault, OR = 2.07, 95% CI [1.25, 3.41]. A significant interaction between LGB identity and sex at birth, OR = 0.34, 95% CI [0.13, 0.88], suggests an elevated sexual harassment risk among male, but not female, LGB service members. Transgender identity predicted sexual harassment and assault at the bivariate level only. These findings suggest that LGBT service members remain at an elevated risk of sexual and/or stalking victimization. As the military works toward more integration and acceptance of LGBT service members, insight into victimization experiences can inform tailored research and intervention approaches aimed at prevention and care for victims.

Integrating Minority Stress Theory and the Interpersonal Theory of Suicide among Sexual Minority Youth Who Engage Crisis Services.

OBJECTIVE: The present study sought to integrate minority stress theory (MST) and the interpersonal theory of suicide (ITS) to better understand high rates of suicide among sexual minority youth (SMY). To date, the ITS and MST have largely advanced independently from one another even though the research base for each theory contains gaps that the other theory may help fill. METHOD: Using data from a national sample of 564 SMY (aged 12-24) recruited from an LGBTQ youth-focused suicide crisis prevention provider, we examined structural equation models to understand how perceived burdensomeness and thwarted belongingness mediate the relationship between minority stress and suicidal ideation and attempt. RESULTS: Sexual minority stress was significantly associated with both perceived burdensomeness and thwarted belongingness in models predicting suicidal ideation and attempt. Moreover, minority stress had a direct effect on suicide attempt and an indirect effect on both suicidal ideation and suicide attempt through burdensomeness. CONCLUSIONS: Given that minority stress is associated with greater thwarted belongingness, perceived burdensomeness, and suicide attempts, there should be greater demand for continuing education centered on sexual minority populations and population-specific services. Identifying burdensomeness as a minority stress-suicide mechanism highlights the potential gains of piloting recently developed burdensomeness interventions among SMY.

Pediatric Resident Attitudes Toward Inpatient Immunization of Children and Adolescents: Highlighting Differences in Human Papillomavirus Vaccination.

Over a decade after its debut, human papillomavirus (HPV) vaccine coverage remains suboptimal. The inpatient setting presents a largely unexplored opportunity to increase vaccination rates. This study aims to describe pediatric resident attitudes toward inpatient immunization and compare differences by vaccine, in particular HPV. An anonymous survey of beliefs and practices regarding inpatient vaccines was distributed to pediatric resident physicians at a single freestanding urban children's hospital in September 2017. A total of 58 surveys were collected (64% response rate). We found that pediatric residents were more likely to report that they never or rarely discuss the HPV vaccine during hospitalization compared with the primary childhood series (P = .001), Tdap (P = .02), and the influenza vaccine (P < .001), and rarely offer the HPV vaccine during hospitalization compared with childhood vaccines (P = .003) and influenza (P = .001). This suggests that provider hesitancy still exists for the HPV vaccine, presenting opportunities for further education and inpatient interventions.

Medical Student Participation in Patient- and Family-Centered Rounding: A National Survey of Pediatric Clerkships.

OBJECTIVE: Pediatrics rotations may be medical students' only experience with patient- and family-centered rounding (PFCR). It is unclear how students participate in or are prepared for PFCR. We surveyed national pediatrics clerkships to determine the prevalence of PFCR and the proportion providing orientation in order to inform a needs assessment for PFCR orientation. METHODS: A 5-item peer-reviewed survey was distributed to the Council on Medical Student Education in Pediatrics (COMSEP) membership as part of a larger survey in 2017. Institutional differences among programs performing PFCR were compared using chi-square and t-tests. Responses to 1 open-ended question were coded and grouped into broad categories using content analysis. RESULTS: The full COMSEP survey received answers from 190 participants representing 103 medical schools. Our questions received 174 responses representing 94 schools (98 training sites) and had an 85% (83/98) prevalence of student PFCR participation. Although most (n = 108; 85%) reported that their students received PFCR orientation, half (n = 62; 49%) considered orientation "informal," and only 2 reported using published curricula. After didactics, the most common orientation materials were handouts (n = 33; 26%), videos (n = 13; 10%), and role play (n = 7; 6%). Orientation was most commonly initiated at the start of clerkship (n = 62; 49%) by clerkship administration (n = 38; 30%), but 20% (n = 26) reported resident-led orientation. Qualitative responses (n = 98) were coded and organized into 4 themes; the greatest perceived challenges for medical students on PFCR were communication and anxiety. CONCLUSIONS: Although most students participate in and receive orientation to PFCR, there is wide variability in the content, timing, and administration of orientation. A nationally disseminated, evidence-based orientation curriculum may reduce educational variability and better prepare students for PFCR.

Military Sexual Assault as a Mediator of the Association Between Posttraumatic Stress Disorder and Depression Among Lesbian, Gay, and Bisexual Veterans.

Lesbian, gay, and bisexual (LGB) civilians report higher rates of sexual assault, posttraumatic stress disorder (PTSD), and depression compared to their heterosexual counterparts. In this study, we compared military sexual assault (MSA), PTSD, and depression in LGB individuals and their non-LGB peers in two community samples of veterans (N = 2,583). Participants were selected for inclusion if they identified as LGB (n = 110) and were matched 1 to 3 on gender and age with non-LGB veterans (n = 330). Chi-square analyses showed significant differences for LGB veterans compared to non-LGB veterans for experiencing MSA (32.7% vs. 16.4%, respectively), p < .001; probable PTSD (41.2% vs. 29.8%, respectively), p = .039; and probable depression (47.9% vs. 36.0%, respectively), p = .039. Multivariable logistic regression analyses showed LGB veterans were 1.93 times more likely to have experienced MSA compared to non-LGB veterans, 95% CI [1.30, 2.88], p = .001. The experience of MSA significantly mediated associations with probable PTSD, odds ratio (OR) = 1.43, 95% CI [1.13, 1.80], p = .003, and probable depression, OR = 1.32, 95% CI [1.07, 1.64], p = .009. As the experience of MSA fully mediates the presence of PTSD and depression among LGB veterans, we highly recommend health providers assess for MSA among LGB veterans, especially those who meet clinical thresholds for PTSD and depression.

Development of the Sexual Minority Adolescent Stress Inventory.

Although construct measurement is critical to explanatory research and intervention efforts, rigorous measure development remains a notable challenge. For example, though the primary theoretical model for understanding health disparities among sexual minority (e.g., lesbian, gay, bisexual) adolescents is minority stress theory, nearly all published studies of this population rely on minority stress measures with poor psychometric properties and development procedures. In response, we developed the Sexual Minority Adolescent Stress Inventory (SMASI) with N = 346 diverse adolescents ages 14-17, using a comprehensive approach to de novo measure development designed to produce a measure with desirable psychometric properties. After exploratory factor analysis on 102 candidate items informed by a modified Delphi process, we applied item response theory techniques to the remaining 72 items. Discrimination and difficulty parameters and item characteristic curves were estimated overall, within each of 12 initially derived factors, and across demographic subgroups. Two items were removed for excessive discrimination and three were removed following reliability analysis. The measure demonstrated configural and scalar invariance for gender and age; a three-item factor was excluded for demonstrating substantial differences by sexual identity and race/ethnicity. The final 64-item measure comprised 11 subscales and demonstrated excellent overall (α = 0.98), subscale (α range 0.75-0.96), and test-retest (scale r > 0.99; subscale r range 0.89-0.99) reliabilities. Subscales represented a mix of proximal and distal stressors, including domains of internalized homonegativity, identity management, intersectionality, and negative expectancies (proximal) and social marginalization, family rejection, homonegative climate, homonegative communication, negative disclosure experiences, religion, and work domains (distal). Thus, the SMASI development process illustrates a method to incorporate information from multiple sources, including item response theory models, to guide item selection in building a psychometrically sound measure. We posit that similar methods can be used to improve construct measurement across all areas of psychological research, particularly in areas where a strong theoretical framework exists but existing measures are limited.

The relationship between preoperative fetal head circumference and 2-year cognitive performance after laser surgery for twin-twin transfusion syndrome.

OBJECTIVE: To determine the relationship between preoperative fetal head circumference (HC) and cognitive performance among children treated with laser surgery for twin-twin transfusion syndrome (TTTS). METHODS: Donor and recipient twin HCs were measured preoperatively (16-26 weeks' gestation) and at 2 years corrected age. Multilevel multivariate regression models were used to test pregnancy and child-level risk factors for lower Battelle Developmental Inventory Second Edition (BDI-2) scores. A repeated-measures ANOVA was used to examine HC growth among recipients and donors between preoperative and 2 years. RESULTS: Ninety-nine children were evaluated. The average BDI-2 score for the cohort was 101.4 (SD = 12.2). After controlling for covariates, larger preoperative HC percentiles were significantly associated with an increase in total BDI-2 scores (ß = 0.29; P < 0.001), where a 12.5% increase in preoperative HC percentile was associated with 1-point increase in total BDI-2 score. The mean recipient and donor twin HC percentiles preoperatively and at age 2 years were 51st percentile vs 20th percentile (P = .050) and 60th percentile vs 49th percentile (P = .676), respectively. CONCLUSION: Smaller preoperative HC percentiles identified children at risk of lower, but still within normal range, total BDI-2 scores. The discordance in HC percentiles between the donor and recipient twin decreased after laser surgery.
