An alternating treatments design with a control condition was used to evaluate and compare the effects of two taped-problem interventions on addition fact fluency. Both taped-problem interventions were identical with the exception of the time delay between the auditory cue of the problem and the answer. One condition used a 2-s delay and the other condition used no delay. Results showed that both taped-problem conditions showed growth in student digits correct per minute scores and that the no-delay condition was slightly more efficient as the taped-problem no-delay procedure took approximately 33% less time. Discussion focuses on using comparative intervention designs to detect nuances in procedures to improve our understanding of math fact interventions that result in the highest learning rates. 相似文献

This study aimed to systematically identify and appraise clinical practice guidelines (CPGs) relating to the assessment and management of suicide risk and self‐harm in children and adolescents. Our research question is as follows: For young people (under 18 years old) presenting to clinical care with suicide ideation or a history of self‐harm, what is the quality of up‐to‐date CPGs? Using the PRISMA format, we systematically identified CPGs meeting our inclusion and exclusion criteria. Subsequently, two independent raters conducted appraisals of the eligible CPGs using the Appraisal of Guidelines for Research and Evaluation II instrument. CPGs were then classified as “poor quality,” “minimum quality,” and “high quality” using operationally defined criteria developed a priori. We identified 10 eligible CPGs published or renewed between 2005 and May 2017. Only the long‐term management of self‐harm CPGs produced by the National Institute for Health and Care Excellence met “high‐quality” criteria. Despite multiple options of CPGs published to choose from, only one was identified as “high quality,” where bias is adequately minimized. Clinicians are advised to direct resources to implementing the “high‐quality” CPG. 相似文献

Nondirectiveness has been a guiding principle for genetic counseling since the founding of the profession. However, its efficacy and appropriateness in this role have been frequently questioned. A workshop at the 2003 Annual Education Conference of the National Society of Genetic Counselors provided audience participation in a discussion of these issues. Participants presented arguments for and against nondirectiveness as a central ethos. They described complex personal transitions in adapting what they had learned about nondirectiveness during training to the realities of the workplace. There was support for flexible approaches to genetic counseling, with varying adherence to nondirectiveness, based on client and family needs and values, clinical circumstances, and desired counseling outcomes. The discussion supports the use of clinical experience, outcomes research, and the experience of other professions to move beyond nondirectiveness and more accurately identify the theoretical bases that underlie genetic counseling in the variety of circumstances in which it is currently practiced. 相似文献

Using a Visual Recognition Memory (VRM) procedure, we examined the effect of encoding time on retention by 1- and 4-year olds. Irrespective of age, shorter familiarization time reduced retention, and longer familiarization time prolonged retention. The amount of familiarization that yielded retention after a given delay decreased as a function of age. 相似文献

The social context of adolescent suicide attempts: interactive effects of parent, peer, and school social relations 总被引:1,自引:0,他引:1

An ecological developmental model of adolescent suicidality was used to inform a hierarchical logistic regression analysis of longitudinal interactions between parent, peer, and school relations and suicide attempts. Reanalyzing data from the National Longitudinal Study of Adolescent Health, it was found that parent relations were the most consistent protective factor, and among boys with prior suicide attempts, school relations augmented the effects of parent relations when peer relations were low. Results indicated the need to understand suicidal behavior as a component of interactive social processes in the design of clinical interventions. 相似文献

In an attempt to illustrate the relevance of psychoanalytic theory and research to behavior medicine, an empirical investigation was conducted of females treated at a high-risk pregnancy specialty clinic (N = 58). Drawing from psychoanalytic object relations theory, it was hypothesized and confirmed that use of projection as a defense mechanism during pregnancy, superimposed on simplistic object relations, predicted an erosion of patient-provider relationships during the pregnancy/postdelivery period. Findings are interpreted through the perspective of mentalization, pertaining to individuals' ability to understand the mental states of self and others, specifically under significant stress. Implications for psychoanalytically oriented assessment and treatment, and for the rift between psychoanalysis and research, are discussed. 相似文献
