Feasibility,Acceptability, and Initial Efficacy of an Online Sexual Health Promotion Program for LGBT Youth: The Queer Sex Ed Intervention

Lesbian, gay, bisexual, and transgender (LGBT) youth experience multiple sexual health inequities driven, in part, by deficits in parental and peer support, school-based sex education programs, and community services. Research suggests that the Internet may be an important resource in the development of sexual health among LGBT youth. We examined the feasibility of recruiting youth in same-sex relationships into an online sexual health intervention, evaluated intervention acceptability, and obtained initial estimates of intervention efficacy. LGBT youth (16 to 20 years old) completed Queer Sex Ed (QSE), an online, multimedia sexual health intervention consisting of five modules. The final sample (N = 202) completed the pretest, intervention, and posttest assessments. The primary study outcomes were sexual orientation identity and self-acceptance (e.g., coming-out self-efficacy), sexual health knowledge (e.g., sexual functioning), relationship variables (e.g., communication skills), and safer sex (e.g., sexual assertiveness). Analyses indicated that 15 of the 17 outcomes were found to be significant (p < .05). Effect sizes ranged from small for sexual orientation (e.g., internalized homophobia) and relationship variables (e.g., communication skills) to moderate for safer sex (e.g., contraceptive knowledge) outcomes. This study demonstrated the feasibility, acceptability, and initial efficacy of QSE, an innovative online comprehensive sexual health program for LGBT youth.     

Understanding Condom Use Decision Making Among Homeless Youth Using Event-Level Data

This is one of the first qualitative event-based studies to understand the various mechanisms through which multiple factors influence condom use decision making among homeless youth. Event-level interviews that explore characteristics of the environment surrounding sexual events were conducted with 29 youth who were asked to describe two recent sexual encounters. In thematic analyses of data across events, reasons that youth gave for engaging in unprotected sex included the expectation of having sex and use of alternative methods of protection against pregnancy. Other nonevent factors that influenced condom use decision making were related to attributes of the partnership (e.g., testing, trust and love, and assessments of risk) and attributes of the youth (e.g., perceptions of diseases, concerns over pregnancy, and discomfort using condoms). Additional event analyses conducted within the same individuals found that decision making was influenced by multiple interacting factors, with different pathways operating for event and nonevent factors. Future interventions should consider taking a multilevel and individualized approach that focuses on event-based determinants of risky sex in this population.     

Living a Calling,Life Satisfaction,and Workplace Climate Among a Lesbian,Gay, and Bisexual Population

Previous research on calling has resulted in a model that relates living a calling to life satisfaction through job satisfaction and life meaning. However, no research has examined this model in a lesbian, gay, bisexual (LGB) population. With a sample of 171 sexual minority adults, the current study aimed to (a) test the fit of an established model of living a calling and life satisfaction and (b) examine how having a supportive LGB workplace climate functioned within this model. Results revealed an excellent fit of the model and that a supportive LGB workplace climate predicted both living a calling and job satisfaction. In addition, the relation of living a calling to life satisfaction was fully mediated by life meaning and job satisfaction, and the relation of climate to life satisfaction was mediated by job satisfaction. These results suggest an expansion of the potential utility of the calling construct to an LGB population.     

Creating more trauma-informed services for children using assessment-focused tools

This article promotes integrating assessment and evidence-based practice in the treatment of traumatized children through a review of two newly developed trauma assessment tools: (1) the Child Welfare Trauma Referral Tool (CWT), and (2) Assessment-Based Treatment for Traumatized Children: A Trauma Assessment Pathway Model (TAP). These tools use pathways and algorithms to increase understanding of individual child trauma victims, and assist professionals working with children to make appropriate referral and treatment decisions within both child welfare and mental health contexts.     

College students use cell phones while driving more frequently than found in government study

OBJECTIVE: Cell phone use while driving is hazardous; it quadruples the risk of a collision and multiplies the risk of a fatality nine-fold. The National Highway Traffic Safety Administration estimates that 8% of young drivers and 5% of all drivers use cell phones while driving. PARTICIPANTS AND METHODS: The authors trained graduate student volunteers to observe the daytime cell phone use of 3,650 drivers leaving the student exits of college parking structures at a large university. RESULTS: The student observers recorded a cell phone usage rate of 11.1%, which was significantly higher than that seen in the National Occupant Protection Use Survey (p<.00001). Female drivers were 1.51 times more likely to be using a cell phone while driving than were men (12.9% vs 8.6%, p<.001), and drivers with passengers were 0.15 times more likely to drive while telephoning than were solo drivers (1.8% vs 12.1%, p<.001). CONCLUSIONS: The authors offer suggestions for possible interventions to reduce this hazardous behavior.     

Decomposition of urban atmospheric carbon in Sonoran Desert soils

Urban atmospheres can have high concentrations of particulate organic carbon (oC) but the rate and fate oC deposition in near-urban ecosystems are rarely quantified. We collected atmospheric particulate matter in Phoenix, AZ and applied these samples to Sonoran Desert soils in a series of laboratory incubation experiments. The addition of fine particulate matter (<2.5 μm aerodynamic diameter) increased microbial respiration in soils collected from the interspaces between desert shrubs. The increase in soil respiration was equivalent to 25% to 30% of the added oC. In contrast, we did not detect increases in respiration when coarse particulate matter (>2.5 μm aerodynamic diameter) was added to interspace soils, suggesting that coarse particulate oC is recalcitrant to microbial decomposition. Due to comparatively higher background levels of C mineralization, we rarely detected changes in microbial respiration when fine or coarse particulate oC was added to soils collected beneath shrub canopies. We measured total atmospheric C concentrations within and surrounding Phoenix and, using inferential methods, estimated rates of deposition that ranged from 0.02 to 0.58 mg C m⁻² d⁻¹ for fine particles and from 0 to 6.15 mg C m⁻² d⁻¹ for coarse particles. Results show that fine atmospheric particulate matter deposited at low rates downwind of Phoenix is a labile oC substrate for soil heterotrophs. In contrast, oC deposited at higher rates as coarse particulate matter may accumulate in soils due to slow microbial decomposition rates.     

Pseudo-likelihood inference for clustered binary data

The maximum likelihood procedure to estimate paraneters of a model has scveral attractive properties including the existence of the covariance matrix which yield asymptotic covariances: for a sample size N the asymptotics are in general of order 1/N. Here we give an asymptotic for the skewness of the distribution of the maximum likelihood estimator of a parameter; this is of order 1/ n2 and this expression is new. Applications relate to the parameters of (i) the Poisson, binomial, and normal density. (ii) the gamna density and (iii) the Beta debsity. Other application are being considered. The expression for the asymptotic skowness at one phase of the study tured out to be unusually complicated involving the asymptotic expressions for variance and bias. When these were identified a much simpler compact expression appeared which we now describe. The work is a much improved treatment of the subject described in Shenton and Bowman (Mariunm likelihood estimation in small samples, Griffin. 1977).
