Violence among youth is a pervasive public health problem. In order to make progress in reducing the burden of injury and mortality that result from youth violence, it is imperative to identify evidence-based programs and strategies that have a significant impact on violence. There have been many rigorous evaluations of youth violence prevention programs. However, the literature is large, and it is difficult to draw conclusions about what works across evaluations from different disciplines, contexts, and types of programs. The current study reviews the meta-analyses and systematic reviews published prior to 2009 that synthesize evaluations of youth violence prevention programs. This meta-review reports the findings from 37 meta-analyses and 15 systematic reviews; the included reviews were coded on measures of the social ecology, prevention approach, program type, and study design. A majority of the meta-analyses and systematic reviews were found to demonstrate moderate program effects. Meta-analyses yielded marginally smaller effect sizes compared to systematic reviews, and those that included programs targeting family factors showed marginally larger effects than those that did not. In addition, there are a wide range of individual/family, program, and study moderators of program effect sizes. Implications of these findings and suggestions for future research are discussed. 相似文献
There are limited data on the medical severity of suicide attempts by intentional self‐poisoning (ISP) associated with ingestion of differing classes of medications and meager data on specific agents. The purpose of the study was to address these gaps. This was an analysis of a consecutive series of ISP cases ages 13 to 65 treated at a U.S. university medical center (N = 671). The outcome, poisoning severity, was dichotomized as “moderate‐severe” and “low” (reference) based on a standard measure. Class of medication (e.g., opiate) and specific agents ingested were the predictors of interest. Covariates were age, sex, and the ingestion of multiple classes of medications. Data were analyzed using multivariate logistic regression models. At the class level, ingestion of opiate was uniquely associated with increased risk for moderate‐severe ISP at a statistically significant level, adjusted odds ratio (95% CI) = 2.97 (1.69, 5.21), p = .0002. Several specific agents were also associated with moderate‐severe ISP. Along with the key role of opiate medications in unintentional overdose morbidity and mortality, opiate medications may also play an important and largely unrecognized role in medically serious suicidal behavior. Results also underscore the variability in toxicity of specific agents within drug classes. 相似文献
Evidence for proximal risk factors for suicide is based on case–control psychological autopsy studies, with these reports showing that mood and substance use disorders are the most prevalent mental disorders among suicide decedents worldwide and are associated with marked risk. However, moderators of risk and the degree of risk associated with (nonalcohol) drug use disorder are unknown. A comprehensive search was used to identify 35 case–control psychological autopsy studies published worldwide over a 30‐year period that were metaanalyzed using random effects models. Major depression, odds ratio (95% confidence interval) = 9.14 (5.53, 15.09), and drug use disorder, OR (95% CI) = 7.18 (3.22, 16.01), had large effect sizes, among other results. Risk estimates associated with major depression were greater in studies with a larger proportion of women and those conducted in Asia compared with other regions. There was no evidence of publication bias or that any one study had a disproportionate impact on findings. Risk for suicide associated with major depression appears to be moderated by sex and/or world region. Drug use disorder is a potent risk factor, illustrating the importance of assessing drug use in clinical risk assessment. 相似文献

Individuals differ considerably in their emotion experience. Some experience emotions in a highly differentiated manner, clearly distinguishing among a variety of negative and positive discrete emotions. Others experience emotions in a relatively undifferentiated manner, treating a range of like-valence terms as interchangeable. Drawing on self-regulation theory, we hypothesised that individuals with highly differentiated emotion experience should be better able to regulate emotions than individuals with poorly differentiated emotion experience. In particular, we hypothesised that emotion differentiation and emotion regulation would be positively related in the context of intense negative emotions, where the press for emotion regulation is generally greatest. To test this hypothesis, participants' negative and positive emotion differentiation was assessed using a 14-day diary protocol. Participants' regulation of negative and positive emotions was assessed using laboratory measures. As predicted, negative emotion differentiation was positively related to the frequency of negative emotion regulation, particularly at higher levels of emotional intensity. 相似文献
There are meager prospective data from nonclinical samples on the link between anxiety disorders and suicide or the extent to which the association varies over time. We examined these issues in a cohort of 309,861 U.S. Air Force service members, with 227 suicides over follow‐up. Mental disorder diagnoses including anxiety, mood, and substance‐use disorders (SUD) were based on treatment encounters. Risk for suicide associated with anxiety disorders were lower compared with mood disorders and similar to SUD. Moreover, the associations between mood and anxiety disorders with suicide were greatest within a year of treatment presentation. 相似文献
A systematic search was performed to identify active, externally funded randomized controlled trials (RCTs) that target suicidal ideation or behavior as a primary or secondary outcome among U.S. military service members, guard–reservists, and veterans. Twenty‐three studies were identified, most funded by the U.S. Department of Defense or U.S. Department of Veterans Affairs. Several innovations were identified based on departures from or modernizations of usual practices and included the targeting of suicide deaths or attempts as primary outcome, delivery of interventions through technology and/or outside clinical settings, and examinations of rarely studied treatments. 相似文献
Two laboratory experiments were conducted to assess the extent to which goal setting theory explains the effects of goals that are primed in the subconscious on task performance. The first experiment examined the effect on performance of three primes that connote the difficulty levels of a goal in the subconscious. Participants (n = 91) were randomly assigned to one of three conditions where they were primed with either a photograph of a person lifting 20 pounds (easy goal), 200 pounds (moderately difficult goal), or 400 pounds (difficult goal). Following a filler task, participants were asked to “press as hard as you can” on a digital weight scale. Participants who were primed with the difficult goal exerted more effort than those who were primed with the moderate or easy goal. The second experiment examined whether choice of goal difficulty level can be primed. Participants (n = 133) were randomly assigned to one of two conditions. Those primed with a difficult goal consciously chose to set a more difficult goal on a brainstorming task than those who were primed with an easier goal. Similarly, their performance was significantly higher. Conscientiousness moderated the subconscious goal–performance relationship while the self‐set conscious goal partially mediated the subconscious goal–performance relationship. 相似文献
Objectives: The aim of this study was to understand the perspectives of people with rheumatic disease have about completing a pilot daily diary questionnaire on fatigue and well-being, with the objective of incorporating these perspectives into future daily studies.
Methods: Twenty-two participants with experience of rheumatic disease-related fatigue attended a focus group and/or an individual interview. Before the focus group or interview, participants completed a one-off quantitative diary about their fatigue and well-being that day. In the focus groups and interviews, participants were asked about their experience completing the questionnaire. Data were analysed using inductive thematic analysis.
Results: Three themes were identified. ‘Concerns about Misinterpretation and Ambiguity’ addressed the elements of the diary questionnaire that were confusing or unclear to participants. ‘Desire to Provide Useful and Accurate Information’ outlined participants’ uncertainty about how to report complex daily experiences. ‘Gaining Personal Insight through Diaries’ revealed the personal benefits participants gained, particularly the development of insight into their fatigue.
Conclusions: People with rheumatic disease are willing to complete a daily diary questionnaire, but emphasise it is important for diary questionnaires to have clear instructions, questionnaire items and response scales. Addressing these concerns will ensure the reliability and validity of quantitative diary data. 相似文献
