BACKGROUND: American Board of Surgery In-Training Exam (ABSITE) performance can be used to assess resident knowledge and to evaluate surgical curriculum. To determine factors that lead to improved resident ABSITE performance, a prospective study was performed. MATERIALS AND METHODS: Thirty-four surgical residents in Program Years 2-5 completed pre- and a post-ABSITE questionnaires about their anxiety, self-efficacy, physical preparation, and academic preparation for the ABSITE. Department records were used to determine resident probationary status and conference attendance. A preliminary analysis of ABSITE scores indicated a significant improvement between 1998 and 1999 percentile scores (paired t = -2. 25, P = 0.03; m = 11.9, SD = 30.5, median = 7). An improvement in percentile rank score was calculated and used as the dependent variable in a stepwise regression analysis. The following served as independent variables: previous exam performance, anxiety, probationary status, amount of sleep before exam, confidence to score in the 25th and the 50th percentiles, and attendance at the three conferences rated most valuable by the residents. RESULTS: Results of the regression analysis demonstrate that all factors account for 62.3% of the variance in improvement scores. A stepwise analysis indicated that the combination of attendance (40.2%) and previous performance (18.3%) was significant in explaining 58.5% of the variance in improvement scores. Furthermore, Pearson's correlations indicated that probationary status (+.58, P = 0.001), anxiety (+0.53, P = 0.001), amount of study (+0.61, P = 0.001), past ABSITE performance (-0.60, P = 0.001), and conference attendance (+0. 56, P = 0.001) were correlated with ABSITE improvement. CONCLUSIONS: This study demonstrates that resident individual effort, past ABSITE performance, and academic conference attendance have led to resident ABSITE improvement.
BACKGROUND: This study investigated attentional allocation in 39 Vietnam combat veterans, 25 with and 14 without posttraumatic stress disorder, assessing P300 amplitudes and latencies during both three-tone and novelty "oddball" tasks. METHODS: The three-tone oddball task consisted of three stimuli: frequent tones (85%), rare target tones (7.5%), and rare distractor tones (7.5%). The novelty oddball task was identical to the three-tone task except that the rare distractor tones were replaced with nonrepeating novel sounds (7.5%). RESULTS: Combat veterans with posttraumatic stress disorder showed significant P300 amplitude enhancements at frontal sites in response to distracting stimuli during the novelty but not during the three-tone oddball tasks. There were no amplitude differences in target tones during either task. CONCLUSIONS: The data suggest that combat veterans with posttraumatic stress disorder demonstrate P300 responses consistent with a heightened orientation response to novel, distracting stimuli. This finding is consistent both with the clinical presentation of the disorder and with theoretical notions that individuals with posttraumatic stress disorder demonstrate information-processing biases towards vague or potentially threatening stimuli.
The purpose of this report was to estimate the association between children's trouble sleeping and anxiety/depression at ages 6 and 11, cross-sectionally and prospectively. Data come from a study of the psychiatric sequelae of low birth weight (LBW: <2500 g). LBW and normal birth weight children were randomly selected from the 1983-1985 newborn lists of an urban and a suburban hospital. Eight hundred and twenty-three children participated at age 6 and, of those, 717 (87.1%) participated at age 11. Achenbach's Child Behavior Checklist (CBCL) and the Teacher Report Form (TRF) were used to obtain ratings of psychiatric problems. The CBCL asked if the child had trouble sleeping during the past 6 months. Children with trouble sleeping had significantly increased odds of anxiety/depression based on mothers' reports (OR=6.9, 95% CI 4.1-11. 4) but not teachers' reports (OR=1.1, 95% CI 0.4-2.7). There was a greater association between sleep and depression at age 11 than at age 6, and among suburban than among urban children. These findings remained when adjusted for birthweight, sex, and mother's history of major depressive disorder. Profile analysis indicated a stronger association of trouble sleeping with anxiety/depression than other psychiatric problems. The association of trouble sleeping at age 6 with incidence of depression at age 11 was not statistically significant (suburban children RR=2.22, 95% CI 0.53-9.23; urban children RR=0.92, 95% CI 0.20-4.18).
