01), with significant improvements in Blocks 9-12 (ps less then .03). Compared to 1 mg/kg, 3 mg/kg caffeine resulted in earlier improvement in target detection (Drug Dose × Block Quadratic, p = .001). This study demonstrated that caffeine acutely and dose-dependently improves sustained attention among adolescents. These results were likely due to the attention-enhancing effect of caffeine, rather than withdrawal reversal, as our sample was characterized by light to moderate caffeine use. This study provides the foundation for further work on the impact of chronic caffeine consumption on cognitive function during adolescence.

The purpose of this study was to (a) pilot the feasibility of SDBT, a manualized, child skills training intervention, (b) determine the potential clinical benefits of SDBT as an independent psychotherapy for ADHD, and (c) examine parents' intervention acceptability. Children of 8-12 years of age with ADHD-combined type (N = 34) were randomly assigned to either SDBT or an "attention control" condition receiving child-centered dyadic therapy (CCDT). SDBT targeted high-frequency behavioral and social demands often challenging for children with ADHD. G Protein antagonist CCDT provided nondirective, experiential psychotherapy without any contingency management methods. Descriptive data revealed a high level of treatment attendance and completion (90%) for both conditions. General linear modeling techniques (multivariate analysis of variance) examined group differences in ADHD outcomes. Results indicated statistically significant differences between the two groups, with greater ADHD symptom reduction for SDBT (Wilks' λ = .61), F(3, 30) = 6.36, p = .002, ηp² = .39. SDBT also demonstrated clinically meaningful changes, with ADHD symptom severity reduced below categorical levels of functional impairment. Despite superior behavioral outcomes for SDBT, intervention acceptability did not significantly differ for the two psychotherapies. Results support SDBT as a feasible, clinically promising, and acceptable intervention for ADHD. Parent satisfaction ratings suggest dyadic therapies may benefit participants beyond symptom reduction. Implications for intervention portability and treating ADHD without direct adult participation are discussed.

Although technology has made EMA data collection easier, concerns remain about the consistency and quality of data collected from participants who are enrolled and followed online. In this study, we used EMA data from a larger study on HIV-risk behavior among men who have sex with men (MSM) to explore whether several indicators of data consistency/quality differed across those who elected to enroll in-person and those enrolled online. One hundred MSM (age 18-54) completed a 30-day EMA study. Forty-five of these participants chose to enroll online. There were no statistically significant differences in response rates for any survey type (e.g., daily diary [DD], experience sampling [ES], event-contingent [EC]) across participants who enrolled in-person versus online. DD and ES survey response rates were consistent across the study and did not differ between groups. EC response rates fell sharply across the study, but this pattern was also consistent across groups. Participants' responses on the DD were generally consistent with a poststudy follow-up Timeline Followback (TLFB) with some underreporting on the TLFB, but this pattern was consistent across both groups. In this sample of well-educated, mostly White MSM r
