An Adaptive Antiretroviral Therapy Adherence Intervention for Youth with HIV Through Text Message and Cell Phone Support with and without Incentives: A Sequential Multiple Assignment Randomized Trial …
Youth living with HIV have low rates of medication adherence. Youth ages 15-24 years with adherence ≤ 80% or with HIV RNA PCRs (VL) ≥ 200 recruited through social media and clinical sites were randomized to brief weekday cell phone support (CPS) calls or daily, two-way, personalized text message (SMS) reminders for 3 months. Those with VL ≥ 200 or adherence ≤ 80% were rerandomized to receive SMS or CPS with monthly incentives for those utilizing …

HIV-Infected Young Men Demonstrate Appropriate Risk Perceptions and Beliefs about Safer Sexual Behaviors after Human Papillomavirus Vaccination
The initial feasibility of a computer-based motivational intervention for adherence for youth newly recommended to start antiretroviral treatment
Young people represent the largest number of new HIV infections, thus youth living with HIV (YLH) are likely to be the largest group to initiate antiretroviral treatment (ART). Adherence patterns for behaviorally infected YLH are not adequate to effectively manage the disease; therefore, novel interventions are needed to improve medication adherence. The purpose of the current study, which will precede a randomized controlled trial, was to assess…

Syndemic Theory and HIV-Related Risk Among Young Transgender Women: The Role of Multiple, Co-Occurring Health Problems and Social Marginalization
Objectives. We assessed whether multiple psychosocial factors are additive in their relationship to sexual risk behavior and self-reported HIV status (i.e., can be characterized as a syndemic) among young transgender women and the relationship of indicators of social marginalization to psychosocial factors. Methods. Participants (n = 151) were aged 15 to 24 years and lived in Chicago or Los Angeles. We collected data on psychosocial factors (low …
Sexual Risk Taking Among Transgender Male-to-Female Youths With Different Partner Types
Objectives. We examined associations between partner types (categorized as main, casual, or commercial) and sexual risk behaviors of sexually active male-to-female (transgender female) youths. Methods. We interviewed 120 transgender female youths aged 15 to 24 years recruited from clinics, community-based agencies, club and bar venues, referrals, and the streets of Los Angeles, California, and Chicago, Illinois. Results. Sexual risk behaviors var…
Transgender Female Youth and Sex Work: HIV Risk and a Comparison of Life Factors Related to Engagement in Sex Work
This study examined the HIV risk behaviors and life experiences of 151 transgender female youth, ages 15-24, in Los Angeles and Chicago. Descriptive analyses and logistic regression modeling were used to identify life factors associated with ever having engaged in sex work. Sixty-seven percent of participants had ever engaged in sex work and 19% self-reported being HIV positive. Many factors were significantly associated with sex work for this sa…
Improving comprehension for HIV vaccine trial information among adolescents at risk of HIV
A simplified version of the HIVNET prototype HIV vaccine process was developed for adolescents at risk of HIV by:(1) reducing reading level; (2) reorganizing; (3) adding illustrations; and (4) obtaining focus group feedback. Then adolescents (N = 187) in three cities were randomly assigned to the standard or simplified version. Adolescents receiving the simplified version had significantly higher comprehension scores (80% correct vs. 72% correct)…
Antiretroviral medication adherence among the Reach HIV-infected adolescent cohort in the USA
Adherence to highly active antiretroviral therapy (HAART) was investigated among HIV-infected adolescents recruited from 13 US cities into the REACH (Reaching for Excellence in Adolescent Care and Health) project, the first large-scale disease progression study of HIV-positive adolescents infected through sexual behaviour or injection drug use. Of 161 subjects, 7% could not correctly identify all their prescribed medications; 11% could identify t…

Intentional Social Action and We-Intentions
In his recent book Professor Tuomela presents a philosophical account of social action that relies upon the presuppositions of his purposive-causal theory of individual action. In particular, the concept of “we-intention” plays as central a role in the new theory as does that of intention in the earlier one. This article examines Tuomela’s concept of “we-intention”. Tuomela’s introduction of the concept into social action theory is motivated by t…
