Suicide is currently the second leading cause of death for ages 15–24 years; reports indicate that 6–8% of American teens have attempted suicide. Rates of suicide and suicide attempts are at least as high, if not higher, for American Indian adolescents and young adults. The Suicidal Ideation Questionnaire (Junior High School Version) (SIQ-JR) could be used to identify young people who may be at risk for attempting suicide, since this questionnaire focuses on suicidal ideation, a major risk factor for suicide attempt. However, little is known about the predictive validity of the SIQ-JR, particularly in American Indian adolescent populations. A suicide attempt cluster at an American Indian boarding school provided the unique opportunity to examine the performance of the SIQ-JR in a group of American Indian high school students who had taken the SIQ-JR approximately 2 months prior to the outbreak of attempts. The SIQ-JR proved to be an excellent predictor of future suicide attempts when compared to other measures of distress: anxiety, depression, and alcohol use. The SIQ-JR is an effective screener for suicide risk in this American Indian adolescent population.  相似文献

The present study leveraged advances in automated essay scoring (AES) technology to explore a proof of concept for a writing screener using the Project Essay Grade (PEG) program. First, the study investigated the extent to which an AES-scored multi-prompt writing screener accurately classified students as at risk of failing a Common Core-aligned English language arts state test. Second, the study explored whether a similar level of classification accuracy could be achieved with a more efficient form of the AES-screener with fewer writing prompts. Third, the classification accuracy of the AES-scored screeners was compared to that of screeners scored for word count. Students in Grades 3–5 (n = 185, 167, and 187, respectively) composed six essays in response to multiple writing-prompt screeners on six different randomly assigned topics, consisting of two essays in each of three different genres (narrative, informative, and persuasive). Receiver operating characteristic (ROC) curve analysis was used to assess classification accuracy and to identify multiple cut scores with associated sensitivity and specificity values, and positive and negative posttest probabilities. Results indicated that the AES-scored multi-prompt screener and screeners with fewer prompts yield acceptable classification accuracy, are efficient, and are more accurate than screeners scored for word count. Overall, results illustrate the viability of writing screening using AES.  相似文献

Two experiments tested the effect of risk of alternative investment opportunities on decision behavior in an escalation context. In the first experiment (n = 170), the risk of the reinvestment option, which had been unsuccessful and incurred a sunk cost, was held equal to that of an alternative investment project. Responsibility for the previous decision was manipulated between these subjects. Subjects were required to choose between the reinvestment option and the alternative. Responsible subjects demonstrated classic reinvestment (escalation) tendencies, and nonresponsible subjects exhibited a significant tendency to avoid reinvestment. Subjects in the second experiment (n = 195) completed the same decision task and were also assigned to high and low responsibility conditions. In this experiment the risk of investing further in a previously chosen project, relative to the risk of the alternative project, was manipulated. Those subjects who were responsible for the first decision (a) demonstrated no preference for or against continued pursuit of the initial project (i.e., there was no escalation tendency) and (b) preferred the less risky of the second investments, regardless of whether it was or was not the initially chosen project. Nonresponsible subjects showed no risk preference or proclivity for reinvestment. The results of these experiments suggest that salient information concerning relative risk dominates the effect of prior performance information when alternative investments are considered. We discuss the implications of these findings for decision theory and for methodology in commitment escalation research.  相似文献

A great deal of research over the past decade has examined the appropriateness of curriculum-based measurement of oral reading (R-CBM) in universal screening. Multiple researchers have meta-analyzed available correlational evidence, yielding support for the interpretation of R-CBM as an indicator of general reading proficiency. In contrast, researchers have yet to synthesize diagnostic accuracy evidence, which pertains to the defensibility of the use of R-CBM for screening purposes. The overall purpose of this research was to therefore conduct the first meta-analysis of R-CBM diagnostic accuracy research. A systematic search of the literature resulted in the identification of 34 studies, including 20 peer-reviewed articles, 7 dissertations, and 7 technical reports. Bivariate hierarchical linear models yielded generalized estimates of diagnostic accuracy statistics, which predominantly exceeded standards for acceptable universal screener performance. For instance, when predicting criterion outcomes within a school year (≤ 9 months), R-CBM sensitivity ranged between .80 and .83 and specificity ranged between .71 and .73. Multiple moderators of R-CBM diagnostic accuracy were identified, including the (a) R-CBM cut score used to define risk, (b) lag in time between R-CBM and criterion test administration, and (c) percentile rank corresponding to the criterion test cut score through which students were identified as either truly at risk or not at risk. Follow-up analyses revealed substantial variability of extracted cut scores within grade and time of year (i.e., fall, winter, and spring). This result called into question the inflexible application of a single cut score across contexts and suggested the potential necessity of local cut scores. Implications for practices, directions for future research, and limitations are discussed.  相似文献

Assessment of risk is one of the key issues in the field of responsible conduct of research which covers discourses of research ethics and research integrity. The principle of minimizing risks and balancing of risks and benefits is one of the main requirements of research ethics. In addition, the content of informed consent that is another fundamental principle of research ethics derives from the assessment of risks and benefits related to a particular research project. Risk assessment also plays a crucial role in methodological design of the research project. This is an important point where research ethics and research integrity discourses overlap. Firstly, because the choice of a control group (e.g., placebo control) is a key ethical issue related to the protection of the research subjects' interests. Secondly, because the quality of the research data, that is one of the key elements of research integrity, is closely connected to the choice of research methodology as well. The problem of biased interpretation or manipulation of risk related features of biomedical research should also be taken into account. Despite the importance of the concept of risk to the field of biomedical research, its relevance has not yet attracted a sufficient attention in the responsible conduct of research debate.  相似文献

First‐episode psychosis (FEP) is a particularly high‐risk period for suicide, in which risk elevates by 60% within a first year of treatment as compared to later stages of illness. To date, much of the literature has focused on individuals with a longer duration of psychosis; thus, there is an urgency for research to examine suicide risk among individuals in FEP in the beginning stage of treatment. This study aimed to identify the relationships between demographic characteristics, symptoms of depression, psychosis (particularly positive symptoms of psychosis), and suicidal ideation among individuals in FEP. Secondary data were obtained from National Institute of Mental Health's Early Treatment Program of the Recovery After an Initial Schizophrenia Episode project (N = 404). Consistent with prior research, participants who experienced suicidal ideation during the study period reported having a longer duration of untreated psychosis and greater symptoms of depression. Further, positive symptoms of psychosis, namely hallucinations and delusions, were found to increase the odds of experiencing suicidal ideation. Findings point toward the implication that depression and positive symptoms of psychosis relate to the experience of suicidal ideation among individuals with a FEP and should be evaluated for and treated in the early stages of treatment.  相似文献

There is a growing body of research suggesting that the first trial of the TOMM may provide an accurate screener of effort in children. During neuropsychological assessments, some circumstances result in only one completed trial of the TOMM. Research on adults reflects that passing scores on Trial 1 (based on Trial 2 cutoff) are highly predictive of passing scores on Trial 2 and the TOMM overall. Pediatric research found that 100% of children and adolescents who passed Trial 1 of the TOMM also passed Trial 2. Our research hypothesis is that children who pass Trial 1 will also pass Trial 2. Data from 75 clinically diagnosed children (ages 6–18 years) found that 64% performed above the published adult TOMM cutoff on Trial 1. All children who passed Trial 1 also passed Trial 2 suggesting support for the research hypothesis. Sensitivity was 1.0, specificity was 0.72, positive predictive value was .33, and negative predictive value was 1.0. These findings suggest that in this sample, the children who performed above the Trial 2 cutoff on Trial 1 also all passed Trial 2 (so there were no false negatives, thus a perfect sensitivity and negative predictive value). Of the 36% of children who did not pass the Trial 1 cutoff, 67% passed on Trial 2. Data clearly support that children passing Trial 1 have a high likelihood of passing Trial 2, thus drawing conclusions about performance validity after passing Trial 1. Conclusions after failing Trial 1 require further investigation.  相似文献

Research on the importance of complete mental health has led to increased focus on students' subjective well-being (i.e., happiness and life satisfaction) coupled with the traditional attention to psychopathology. Although screeners for psychopathology abound, the present project is novel in applying best practices in universal screening to grade level-wide assessment of children's life satisfaction, followed by implementation of a positive psychology intervention for students identified through the screener. In this case study of 375 third- to fifth-grade students in one elementary school, 93.6% participated in the screening, 11.2% qualified for supplemental services based on screening cutoff scores, and 4.8% took part in the targeted intervention to improve subjective well-being. Repeated measures analysis of mean scores revealed the intervention increased children's life satisfaction, lending support for the value of universal screeners in the process of service delivery. Implications for practice regarding universal screening and intervention for life satisfaction are discussed.  相似文献

Bioethicists broadly agree that there is a limit to the level of net risk that biomedical research may permissibly impose on participants, even in cases where the potential of that research to improve the health of the population health would be great. Although some may permissibly volunteer to take on some degree of pro-social risk, no one, not even a willing volunteer, may ever be outright sacrificed for others. One might think this perspective, if correct, makes it effectively impossible to study interventions with high intrinsic risks. But I describe a method – risk dilution – by which an extremely high-risk intervention can nonetheless be effectively studied in the context of an acceptably low-risk trial. I then defend risk dilution from objections.  相似文献

Describes the implementation of a collaborative preventive intervention project (Healthy Schools) designed to reduce levels of bullying and related antisocial behaviors in children attending two urban middle schools serving primarily African American students. These schools have high rates of juvenile violence, as reflected by suspensions and expulsions for behavioral problems. Using a quasi-experimental design, empirically based drug and violence prevention programs, Bullying Prevention and Project ALERT, are being implemented at each middle school. In addition, an intensive evidence-based intervention, multisystemic therapy, is being used to target students at high risk of expulsion and court referral. Hence, the proposed project integrates both universal approaches to prevention and a model that focuses on indicated cases. Targeted outcomes, by which the effectiveness of this comprehensive school-based program will be measured, are reduced youth violence, reduced drug use, and improved psychosocial functioning of participating youth.  相似文献

This paper describes a feasibility study of a peer-delivered prevention intervention to identify mothers at high risk for depression and facilitate engagement in mental health services for their emotional health. Sixteen family peer advocates and their supervisors partnered with academic researchers over a period of 6 months to develop a four-session intervention that focused on identifying symptoms of depression, providing education about depression and treatment, actively linking caregivers to treatment for their own emotional health, and assisting caregivers in becoming active participants in their mental health care. Collaborating with peers to develop the model enhanced its perceived relevance and utility, and resulted in an intervention that was complimentary to their roles and the mission of peer-delivered support services. Peer/professional partnerships may be beneficial for enhancing the feasibility and acceptability of research efforts; the impact of peers’ participation in the current project and the need for future research to develop and study peer-delivered models is discussed.  相似文献

Primary prevention focuses on the reduction of risk factors. Children of mothers with an eating disorder are a proven “at risk” group, because children internalise their experiences. Prevention in the field of eating disorders has as yet only addressed children of seven or eight upwards and only in school‐based programs which did not incorporate mothers. This project targeted mothers with an eating disorder who had children under the age of thirteen. The hypothesis is that if these mothers can be encouraged to change damaging behaviour that their children are likely to model, we can attempt to break the cycle of dysfunction. This is a qualitative and quantitive research project, carried out with standardised measures and semi‐structured interviews before and after a nineteen week therapy group, with six and twelve month follow ups. The group consisted of eight mothers. This paper describes the group and provides a case study of one participant. The initial analysis suggests that the support of a therapeutic group allowed this mother enough space for reflection. She became aware of her dysfunctional behaviour and was able to begin to understand the underlying reasons behind it. This led to an improvement in her own Eating Disorder (ED) and she was subsequently able to make change in her responses to her children's needs.  相似文献

We present data from an ongoing research project on the cognitive, emotional and neuropsychological basis of risk behaviour. The main aim of the project is to build a model of risk behaviour so that if we know certain cognitive, behavioural and emotional variables, we will be able to predict decisions made in the face of uncertainty and risk, with the final goal of designing programs for evaluating, preventing and controlling risk behaviour. The objective of the present study was to look for individual differences in hazard perception during a static riding simulation and their relationship with mental workload. We used a multidimensional methodology, including behavioural, subjective and physiological data. The behavioural measures were obtained in a static riding simulation during eight hazard situations. We evaluated whether eye activity measures correlated with cognitive workload and different types of risky behaviours. Eye movement parameters were measured using a video-based eye tracking system. We found that risk-prone individuals showed specific patterns of risky behaviours and that peak of saccadic velocity and subjective mental workload indexes were both reliable indicators of risk proneness. Mental workload was higher for participants showing attitudes to risk behaviours probably because of a lack of conscious awareness of specific cues indicating dangerous scenarios.  相似文献

In order to advance the detection and prevention of suicide, recent research has focused on predictors of suicidal ideation and behavior such as negative cognitive styles, dysfunctional attitudes, hopelessness, and rumination. In this study the relationships among these risk factors in the context of the Attention Mediated Hopelessness (AMH) theory of depression are examined. One hundred and twenty-seven undergraduates in the Cognitive Vulnerability to Depression (CVD) project were followed for 2.5 years. The CVD project followed initially nondepressed freshmen, at either high or low cognitive risk for depression, in order to predict onsets and recurrences of depressive disorders. The presence and duration of suicidal ideation were predicted prospectively by rumination and hopelessness, and hopelessness partially mediated the relationship between rumination and ideation and fully mediated the association between rumination and duration of suicidality. Further, rumination mediated the relationship between cognitive vulnerability and suicidal ideation.  相似文献

Later-born siblings of children with autism spectrum disorder are considered at biological risk for autism spectrum disorder and the broader phenotype. Early screening may detect first signs of autism spectrum disorder and expedite diagnosis and early intervention. In this follow-up study, we re-examine a validated second-degree autism spectrum disorder screener for children at biological risk of autism spectrum disorder, the parent observation of early markers scale. Using available follow-up information up to age 13 years, 110 children (the original 108 infants plus 2 infants recruited after the completion of the original study) were divided into three groups: diagnosed group (n?=?13), lost diagnosis group (n?=?5), and undiagnosed group (n?=?92). The parent observation of early markers scale continued to show acceptable predictive validity. The parent observation of early markers scale total scores and mean number of elevated items were significantly higher in the diagnosed group than the undiagnosed group. The lost-diagnosis group did not differ from the undiagnosed group on parent observation of early markers scale total scores and elevated items at any age, but the lost-diagnosis group had significantly lower total scores, and number of elevated items than the diagnosed group starting at 18 months. Both autism spectrum disorder core and subsidiary behaviors differentiated the diagnosed and undiagnosed groups from 9 to 36 months of age. We hereby provide further evidence that the parent observation of early markers scale may serve as a low-cost early screener for autism spectrum disorder in at-risk children and pinpoint specific developmental ,and behavioral problems that may be amenable to very early intervention.  相似文献

This article describes (1) an intrafamilial child sexual abuse case and (2) the multidisciplinary research project which developed from its outcome. The research project., in existence since 1987, is a task force of the Committee an Children, Youth, and Families of the New Jersey Psychological Association and is co-sponsored by the Committee on Child Psychiatry of the New Jersey Psychiatric Association. The research aims at developing an objective behavioral assessment instrument to validate child sexual abuse allegations, and at achieving a clinical-legal consensus regarding the credibility of the instrument. Ranking, reliability, and validity studies are described.  相似文献
