Neurodevelopmental model of long-term outcomes of adult survivors of childhood brain tumors.

Childhood brain tumors and related treatments disrupt the developing brain and have a cascading impact on core cognitive skills and intellectual (intelligence quotient [IQ]) and academic achievement outcomes. Theoretical models for this cascade have been developed based on the literature, but no studies thus far have empirically evaluated the models. The current study aimed to empirically test the two extant models and generate a new data-driven model of the relationships among neurodevelopmental risk factors, core cognitive skills (i.e., processing speed, attention span, working memory), and IQ and achievement outcomes. Fifty-seven adult survivors of childhood brain tumors and fifty-seven demographically matched neurotypical individuals were included in the current study. The average age at brain tumor diagnosis was 8 years, and the average time since diagnosis was 17 years. Three a priori path models tested the hypothesized relationships among variables. Results of the path analyses revealed that the hybrid model best fit the data for both survivors and controls based on all statistical criteria. For survivors, processing speed was the core cognitive skill most widely associated with neurodevelopmental risk factors and outcomes. However, working memory and attention span also had unique contributions to IQ and academic achievement. Processing speed appears to be the central cognitive skill that disrupts the other core cognitive skills of attention span and working memory, and all three make a unique contribution to IQ and academic achievement. This is best demonstrated by a novel neurodevelopmental model that combines components of two earlier untested theoretical models.

Variability in Condom Use Trends by Sexual Risk Behaviors: Findings from the 2003-2015 National Youth Risk Behavior Surveys.

OBJECTIVE: This study aimed to examine variability in condom use trends by sexual risk behavior among US high school students. METHODS: Data were from the 2003-2015 national Youth Risk Behavior Surveys conducted biennially among a nationally representative sample of students in grades 9 to 12. We used logistic regression to examine variability in trends of condom use during last sexual intercourse among female and male students by 4 sexual risk behaviors: drank alcohol or used drugs before last sexual intercourse, first sexual intercourse before age 13 years, 4 or more sex partners during their life, and 2 or more sex partners during the past 3 months. RESULTS: Between 2003 and 2015, significant declines in self-reported condom use were observed among black female (63.6% in 2003 to 46.7% in 2015) and white male students (69.0% in 2003 to 58.1% in 2015). Among female students, declines in self-reported condom use were significant only among those who drank or use drugs before last sexual intercourse, had 4 or more sex partners during their life, or had 2 or more sex partners during the past 3 months. There was a significant interaction between trends in condom use and first sexual intercourse before age 13 years, suggesting more pronounced declines among female students who initiated first sexual intercourse before age 13 years compared with their female peers. Trends did not vary by sexual risk behavior for male students. CONCLUSIONS: Results suggest that declines in self-reported condom use have occurred among female students at greater risk for acquiring a sexually transmitted disease.

Community Data Collection with Children of Mothers Living with HIV: Boundaries of the Researcher Role.

The TRACK-II program is a multi-site, community-based randomized controlled trial evaluating an intervention to assist mothers living with HIV (MLH) in disclosing their HIV status to their young children. Many participants-both mothers and children-reported significant depression and/or suicidal ideation, a phenomenon that presented ethical challenges. This article focuses on participants at one site (Atlanta). Through the vignette of "Jordan," we describe ethical challenges that may arise when faced with the responsibility of maximizing participants' safety while maintaining the boundaries of the researcher role. Guided by community psychology values, our team has taken measures within our role as researchers to empower and protect children and mothers endorsing suicidal ideation. For example, we have relied on relationships with community-based organizations and AIDS service organizations to connect HIV-affected families to mental health services. Furthermore, we have expanded our system of documentation to follow-up adequately with families at risk, and we track family resources to promote a strengths-based framework. We have solicited families' feedback about their supports and needs to understand how we may best serve them by connecting them to the resources they report needing most and empowering them to care for themselves.
