Both future orientation and impulsivity are intrinsic parts of an adolescent’s self-control, and empirical evidence clearly establishes them as crucial features on the origin of juvenile deviant behavior. However, we do not yet fully understand how these variables relate in explaining deviant conduct. In the present study, we tested a mediation model between these variables among 126 Portuguese adolescents. Findings support the mediation model in analysis, namely that impulsivity fully mediates the effect of future orientation on deviant behavior. In conclusion, our results suggest that lesser future orientated youth develop impulsive behavior which, in turn, explains their higher deviant conduct. 相似文献

Van der Linden's (2007, Psychometrika, 72, 287) hierarchical model for responses and response times in tests has numerous applications in psychological assessment. The success of these applications requires the parameters of the model to have been estimated without bias. The data used for model fitting, however, are often contaminated, for example, by rapid guesses or lapses of attention. This distorts the parameter estimates. In the present paper, a novel estimation approach is proposed that is robust against contamination. The approach consists of two steps. In the first step, the response time model is fitted on the basis of a robust estimate of the covariance matrix. In the second step, the item response model is extended to a mixture model, which allows for a proportion of irregular responses in the data. The parameters of the mixture model are then estimated with a modified marginal maximum likelihood estimator. The modified marginal maximum likelihood estimator downweights responses of test-takers with unusual response time patterns. As a result, the estimator is resistant to several forms of data contamination. The robustness of the approach is investigated in a simulation study. An application of the estimator is demonstrated with real data. 相似文献

To determine changes in rates of drug ingestions in 10–14 year old children in our country, a retrospective chart review of 10–14 year olds hospitalized for drug ingestion between 1993–1995 and 2000–2004 was performed. Odds ratios and Chi‐square were used for analyses. From 1993–1995 there were 92.8 ingestions/100,000 children/year; from 2000–2004 there were 63.3 ingestions/100,000 children/year. More males ingested in 2000–2004 than 1993–1995 (26.3% vs. 14.2% O.R. 2.15 [1.19, 3.92]). More patients took psychiatric medications in 2000–2004 than 1993–1995 (38.9% vs. 27.0%, O.R. 1.72 [1.06, 2.80]). More patients ingested SSRIs in 2000–2004 than 1993–1995; fewer ingested tricyclics. Hospitalization rates for drug ingestions have decreased. There has been a change in drug ingested, and more males are ingesting drugs. 相似文献

The World Health Organization identified the promotion of “Nurturing Care Environments” as a global health priority. Responsive caregiving, 1 of 5 domains describing nurturing care, is critical for healthy child development. Relatively little research has evaluated population-level interventions aimed to increase responsive caregiving during the first 1,000 days of an infant's life. In this pilot study, we evaluated an intervention designed for population-level dissemination that targeted responsive caregiving. The self-guided behavioral skills training aimed to teach mothers to imitate infant vocalizations. The intervention was delivered within an on-line asynchronous training. All 3 mothers increased vocal imitative behavior following training without receiving coaching or behavior-specific feedback from an implementer. The results offer a preliminary proof of concept with implications for population-level intervention design and evaluation. 相似文献

In qualitative research paradoxes abound in research design, sampling, generalisation, ethics and the behaviour of the researcher. The ultimate paradox is that qualitative inquiry is impossible — both conceptually and practically — yet it still goes on. It must do so if the professions of counselling and psychotherapy are to advance. 相似文献

Latent trait models for response times in tests have become popular recently. One challenge for response time modeling is
the fact that the distribution of response times can differ considerably even in similar tests. In order to reduce the need
for tailor-made models, a model is proposed that unifies two popular approaches to response time modeling: Proportional hazard
models and the accelerated failure time model with log–normally distributed response times. This is accomplished by resorting
to discrete time. The categorization of response time allows the formulation of a response time model within the framework
of generalized linear models by using a flexible link function. Item parameters of the proposed model can be estimated with
marginal maximum likelihood estimation. Applicability of the proposed approach is demonstrated with a simulation study and
an empirical application. Additionally, means for the evaluation of model fit are suggested. 相似文献

We evaluated response blocking with programmed stimulus control, wearing tennis wrist bands, to reduce motor stereotypy in a student with autism. Response blocking was effective and subsequent analysis revealed that wearing the tennis wrist bands alone maintained low frequency stereotypy. Results suggest that controlling effects from a procedure such as response blocking can be transferred to a programmed stimulus in the absence of physical intervention. 相似文献

Impaired social skills represent a fundamental deficit for children with Autism Spectrum Disorders (ASD). Despite the potential importance of “good sportsmanship,” this social skill has received relatively little attention in the literature. The current study utilized a Behavioral Skills Training (BST) approach to teach three sportsmanship skills (i.e., complimenting, turn taking, and being a good sport) during video game play (Wii Sports). Six children with ASD completed this study. Findings suggest BST can be used effectively to teach sportsmanship skills to children with ASD. The use of video-game technology as part of social skills intervention programs is also discussed. 相似文献
