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

Our aim was to explore the role of parents in the transmission of stereotypical body size attitudes and awareness of weight loss strategies to preschool children. Participants were 279 3‐year‐old children and their parents, who provided data at baseline and 1 year later. Parents completed self‐report body size attitude and dieting measures. Child weight bias and awareness of weight loss strategies were assessed through interview. Over time, negative associations with large bodies and awareness of weight loss strategies increased. Fathers’ attitudes prospectively predicted boys’ weight bias and awareness of weight loss strategies. Among girls, parental attitudes were less predictive. Findings confirm the importance of fathers in the development of boys’ body attitudes and inform prevention programmes.  相似文献

OBJECTIVE: Approximately 6,000 Americans die every year awaiting an organ transplant. Health promotion interventions may alleviate the shortage of viable organs by increasing the number of registered organ donors. This study is the first to evaluate the differential effectiveness of various organ donor messages in naturalistic settings. DESIGN: A 4 (Appeal)x4 (Exemplar)x4 (Location) counterbalanced quasi-experimental design was implemented. MAIN OUTCOME MEASURE: The behavioral outcome measure was the number of individuals who registered to be organ donors at computer kiosks. RESULTS: A number of significant main effects and interactions emerged. Most notably, of the 4 different appeals (counterargument, emotional, motivating action, dissonance), counterargument was by far the most efficacious, especially in academic-type settings (library, university, community college); the emotional appeal was most successful in hospitals. CONCLUSIONS: The findings from this study have implications for both organ donor investigations and health campaign research in general. Statistical interactions highlight the importance of evaluating multiple exemplars in multiple locations for each type of appeal when conducting health campaign research.  相似文献
