Mother Knows Best? Mother and Child Report of Behavioral Difficulties of Children of HIV-Infected Mothers

Children of HIV-infected mothers have more psychosocial adjustment difficulties than do those of noninfected mothers. In this study, child psychosocial adjustment in children of HIV-infected women is examined across the three stages of HIV-infected: asymptomatic, symptomatic and AIDS. Participants were 99 HIV-infected women and 148 noninfected women. Children were not identified as being HIV infected. Mother and child reports of behavioral difficulties are compared, and competing hypotheses about mother report of child behavior difficulties are tested. Results indicate an ascending linear trend for child report of internalizing and externalizing difficulties from the noninfected stage through increasingly severe stages of HIV-infection. According to mother report, child externalizing and internalizing difficulties are nonlinear, as mothers report an increase through the infected symptomatic stage, then a decrease in the AIDS stage. Implications for assessment, prevention and intervention in families with maternal HIV infection are discussed.

Personal Strategies for HIV Prevention: The Development and Validation of a Strategy-Coding Instrument1

This paper describes the development of a coding instrument to classify college students' strategies for preventing HIV infection, and examines the association of distinct strategies with social cognitive and behavioral measures related to safer sexual behavior. This instrument classifies each strategy into both a content domain (e.g., using condoms, remaining abstinent, limiting sexual partners), and 3 distinct dimensions: commitment, specificity, and effectiveness. We examine the reliability and validity of this instrument by showing the discriminative associations of each dimension with social cognitive and behavioral measures, and demonstrate the differential importance of distinct dimensions in predicting behavior in different content domains. Discussion focuses on the importance of tailoring HIV prevention messages to change strategy dimensions in order to maximize behavior change.     

Examination of the PC-PTSD in previously deployed Air Force Medical Service personnel

This study assessed the performance of the PC-PTSD in diagnosing postdeployment posttraumatic stress disorder (PTSD) in a cohort of Air Force Medical Services personnel (N = 18,530). The prevalence of PTSD in the cohort was 5.18% based on medical record data. The area under the receiver operating characteristic curve was 0.69, indicating poor classification accuracy. Sensitivity was 47.55%, specificity was 90.68%, positive predictive value was 21.79%, and negative predictive value was 96.94%. The positive and negative likelihood ratios were 5.10 and 0.58, respectively. Several risk factors were found to be associated with a diagnosis of postdeployment PTSD: being a nurse, being enlisted in the medical service career field, being enlisted in the mental health service career field, those over age 30, being a member of the Active Duty service component, and having one’s first deployment be to Iraq. Being an officer was found to be a protective characteristic. These factors could potentially improve screening for PTSD among Air Force healthcare personnel.     

An Investigation of Student-Selected and Parent-Delivered Reading Interventions

In this study, we examined whether individualized, student-selected, parent-delivered reading interventions would produce generalized oral reading fluency improvements. Three 3rd-grade students received reading fluency interventions (repeated readings, modeling, error correction, and flashcard instruction) 1 at a time and were shown the results that each intervention produced. The students then selected the intervention strategies they wanted their parents to use. We trained parents in the student-selected reading intervention package who delivered the interventions for 4–5?weeks, and students were given the opportunity to earn rewards for generalized performance improvements at the end of each week in school. Using an alternating treatments design, results of parent tutoring were compared to a control condition that included a reinforcement contingency for generalized performance improvements to control for reinforcement effects across conditions. Generalized improvements in oral reading fluency (to high-word-overlap passages) were found for all participants. Results are discussed in terms of how educators can improve parent-tutoring outcomes by influencing students’ motivation to engage in tutoring procedures.     

Top-down versus bottom-up attentional control: a failed theoretical dichotomy

Prominent models of attentional control assert a dichotomy between top-down and bottom-up control, with the former determined by current selection goals and the latter determined by physical salience. This theoretical dichotomy, however, fails to explain a growing number of cases in which neither current goals nor physical salience can account for strong selection biases. For example, equally salient stimuli associated with reward can capture attention, even when this contradicts current selection goals. Thus, although 'top-down' sources of bias are sometimes defined as those that are not due to physical salience, this conception conflates distinct--and sometimes contradictory--sources of selection bias. We describe an alternative framework, in which past selection history is integrated with current goals and physical salience to shape an integrated priority map.     

Unpacking Cultural Variations in Peak-Experiences: Cross-Cultural Comparisons of Early Childhood Recollection Between Hong Kong and Brazil

In this cross-cultural study, 115 Hong Kong Chinese and 117 Brazilian college students described a childhood peak-experience (occurring before the age of 14) and provided a self-rating on its enduring impact. Among various categories of peak-experiences, both Hong Kong Chinese and Brazilians reported interpersonal joy most frequently; the second most frequently reported category was external achievement for the Hong Kong sample and developmental landmark for the Brazilian sample. Compared with Brazilians’ narratives, those of Hong Kong Chinese were more social-focused, involving greater number of other people, but less specific. These characteristics of autobiographical memory, i.e., memory focus (self vs. social), memory specificity (specific vs. general), and the number of other people involved, significantly mediated the relation between culture and interpersonal joy. The present findings have extended research on peak-experiences to cross-cultural contexts and incorporated measures of autobiographical memory to unpack cultural variations in these two collectivist societies.
