The purpose of this study was to examine the longitudinal relationship between aggression and suicide ideation when controlling for other externalizing (i.e., alcohol misuse and risk‐taking) and internalizing (i.e., depression and sleep problems) risk factors in an active duty, military sample. Preexisting data from a longitudinal study were analyzed to assess the wellness of service members across the deployment cycle. Participants were 944 active duty service members (95% male, 48% between 18 and 24 years old) who completed surveys upon initial return from deployment and approximately 3 months later. After controlling for other externalizing (alcohol misuse, risk‐taking) and internalizing (depression, sleep problems) risk factors, service members reporting aggression were significantly more likely to report suicide ideation than those reporting no aggression (OR = 3.19; OR 95% CI: 1.16–8.80). The independent nature of the relationship between anger and suicidality suggests aggression may be an important indicator of suicidality for service members. Understanding the role of aggression in suicidality may improve the ability to identify at‐risk service members and to develop effective interventions to reduce suicide risk. 相似文献

As a part of classroom management, teachers face the question of how and where to seat their students. However, it is far from clear what considerations teachers have when making seating arrangements. Therefore, in this study seating arrangement considerations from 50 teachers in grades 4–6 of elementary school were assessed. In Phase 1, teachers were interviewed about their goals and considerations for classroom seating arrangements. Teachers mentioned between 2 and 19 reasons for placing students at specific places in the classroom, with mostly academic considerations. They mainly preferred arrangements in small groups to promote student cooperation. In Phase 2, teachers completed a questionnaire about seating arrangements. This allowed us to examine individual differences between teachers related to gender, years of experience, and beliefs, and the concurrence between the interview and questionnaire data. Teachers reported multiple and various considerations for seating arrangements. Correlations with their general student-oriented or subject-oriented beliefs and personal characteristics were low. The concurrence between measurement methods also was low. The discussion focused on teacher awareness of classroom seating arrangements as an important part of classroom management and a tool for prevention and intervention. 相似文献

The Feeding Scale provides a reliable rating of mother-infant/toddler interactions during a 20-minute feeding in a laboratory setting. The scale consists of 46 mother and infant behaviors, which are rated at the end of the feeding session. Observations of mother—infant interactions during two feedings separated by 2 weeks showed considerable stability. Five subscale scores are derived (1) Dyadic Reciprocity, (2) Dyadic Conflict, (3) Talk and Distraction, (4) Struggle for Control, and (5) Maternal Non-Contingency, Predictive validity of the Feeding Scale has been demonstrated and it discriminates between infants with and without feeding disorders as well as three diagnostic categories of feeding-disordered infants. The Feeding Scale can be used with infants and toddlers ranging in age from 1 month to 3 years. © 1997 Michigan Association for Infant Mental Health 相似文献

Sleep Loss and Temporal Memory 总被引:17,自引:0,他引:17

Historical evidence suggests that sleep deprivation affects temporal memory, but this has not been studied systematically. We explored the effects of 36 hr of sleep deprivation on a neuropsychological test of temporal memory. To promote optimal performance, the test was short, novel, and interesting, and caffeine was used to reduce 'sleepiness'. A total of 40 young adults were randomized into four groups: control + caffeine (Cc), control + placebo (Cp), sleep deprived + caffeine (SDc), and sleep deprived + placebo (SDp). Controls slept normally. Caffeine (350 mg) or placebo were given just prior to testing. The task comprised colour photographs of unknown faces and had two components: recognition memory (distinction between previously presented and novel faces), and recency discrimination (temporal memory), when a previously shown face was presented. An interpolated task, self-ordered pointing, acted as a distraction. Caffeine had no effects within control conditions, but significantly reduced subjective sleepiness in SDc. Recognition was unaffected by sleep deprivation, whereas for recency, sleep deprivation groups scored significantly lower than controls. There was no significant improvement of recency with caffeine in the SDc group. Both sleep deprivation groups had poorer insight into their performance with recency. Self-ordered pointing remained unchanged. In conclusion, sleep deprivation impairs temporal memory (i.e. recency) despite other conditions promoting optimal performance. 相似文献

This paper presents the results of a technology transfer project designed to transfer knowledge about model behavioral intervention
projects that significantly decreased HIV-related risk behaviors. The National AIDS Demonstration Research Program Technology
Transfer (NADR TT) Project encompassed: (1) preparation of manuals based on successful intervention research; (2) convening
of 7 Regional meetings on Behavior Change Strategies for Injection Drug Users (IDUs); and (3) conduct of twenty-three state
implementation training events. An evaluation of the NADR TT project showed that it was successful in its efforts to transfer
knowledge regarding model intervention programs. Participants expressed an increased level of confidence in their ability
to implement the model and individual model elements were perceived to be useful to—and implemented by—participants. Results
also pointed out that significant barriers to implementation of model elements of the behavioral interventions exist. 相似文献

A new procedure analogous to the analysis of variance (ANOVA), called the bisquare-weighted ANOVA (bANOVA), is described. When a traditional ANOVA is calculated, using samples from a distribution with heavy tails, the Type I error rates remain in check, but the Type II error rates increase, relative to those across samples from a normal distribution. The bANOVA is robust with respect to deviations from a normal distribution, maintaining high power with normal and heavy-tailed distributions alike. The more popular rank ANOVA (rANOVA) is also described briefly. However, the rANOVA is not as robust to large deviations from normality as is the bANOVA, and it generates high Type I error rates when applied to three-way designs. 相似文献
