The R package mice imputes incomplete multivariate data by chained equations. The software mice 1.0 appeared in the year 2000 as an S-PLUS library, and in 2001 as an R package. mice 1.0 introduced predictor selection, passive imputation and automatic pooling. This article documents mice, which extends the functionality of mice 1.0 in several ways. In mice, the analysis of imputed data is made completely general, whereas the range of models under which pooling works is substantially extended. mice adds new functionality for imputing multilevel data, automatic predictor selection, data handling, post-processing imputed values, specialized pooling routines, model selection tools, and diagnostic graphs. Imputation of categorical data is improved in order to bypass problems caused by perfect prediction. Special attention is paid to transformations, sum scores, indices and interactions using passive imputation, and to the proper setup of the predictor matrix. mice can be downloaded from the Comprehensive R Archive Network. This article provides a hands-on, stepwise approach to solve applied incomplete data problems.

Emotion-regulation strategies across psychopathology: A meta-analytic review.

To revise 1998 recommendations on childhood obesity, an Expert Committee, comprised of representatives from 15 professional organizations, appointed experienced scientists and clinicians to 3 writing groups to review the literature and recommend approaches to prevention, assessment, and treatment. Because effective strategies remain poorly defined, the writing groups used both available evidence and expert opinion to develop the recommendations. Primary care providers should universally assess children for obesity risk to improve early identification of elevated BMI, medical risks, and unhealthy eating and physical activity habits. Providers can provide obesity prevention messages for most children and suggest weight control interventions for those with excess weight. The writing groups also recommend changing office systems so that they support efforts to address the problem. BMI should be calculated and plotted at least annually, and the classification should be integrated with other information such as growth pattern, familial obesity, and medical risks to assess the child’s obesity risk. For prevention, the recommendations include both specific eating and physical activity behaviors, which are likely to promote maintenance of healthy weight, but also the use of patient-centered counseling techniques such as motivational interviewing, which helps families identify their own motivation for making change. For assessment, the recommendations include methods to screen for current medical conditions and for future risks, and methods to assess diet and physical activity behaviors. For treatment, the recommendations propose 4 stages of obesity care; the first is brief counseling that can be delivered in a health care office, and subsequent stages require more time and resources. The appropriateness of higher stages is influenced by a patient’s age and degree of excess weight. These recommendations recognize the importance of social and environmental change to reduce the obesity epidemic but also identify ways healthcare providers and health care systems can be part of broader efforts.

Expert Committee Recommendations Regarding the Prevention, Assessment, and Treatment of Child and Adolescent Overweight and Obesity: Summary Report

Ten per cent of the world’s school-aged children are estimated to be carrying excess body fat (Fig. 1), with an increased risk for developing chronic disease. Of these overweight children, a quarter are obese, with a significant likelihood of some having multiple risk factors for type 2 diabetes, heart disease and a variety of other co-morbidities before or during early adulthood. The prevalence of overweight is dramatically higher in economically developed regions, but is rising significantly in most parts of the world. In many countries the problem of childhood obesity is worsening at a dramatic rate. Surveys during the 1990s show that in Brazil and the USA, an additional 0.5% of the entire child population became overweight each year. In Canada, Australia and parts of Europe the rates were higher, with an additional 1% of all children becoming overweight each year. The burden upon the health services cannot yet be estimated. Although childhood obesity brings a number of additional problems in its train – hyperinsulinaemia, poor glucose tolerance and a raised risk of type 2 diabetes, hypertension, sleep apnoea, social exclusion and depression – the greatest health problems will be seen in the next generation of adults as the present childhood obesity epidemic passes through to adulthood. Greatly increased rates of heart disease, diabetes, certain cancers, gall bladder disease, osteoarthritis, endocrine disorders and other obesityrelated conditions will be found in young adult populations, and their need for medical treatment may last for their remaining life-times. The costs to the health services, the losses to society and the burdens carried by the individuals involved will be great. The present report has been written to focus attention on the issue and to urge policy-makers to consider taking action before it is too late. Specifically, the report:

Obesity in children and young people: a crisis in public health.

The Structured Clinical Interview for DSM-IV Childhood Disorders (Kid-SCID) is a semi-structured interview for the classification of psychiatric disorders in children and adolescents. This study presents a first evaluation of the psychometric properties of the Kid-SCID in a Dutch sample of children and adolescents who had been referred to an outpatient treatment centre for mental health problems. Results indicated that the inter-rater reliability of the Kid-SCID classifications and the internal consistency of various (dimensional) criteria of the diagnoses were moderate to good. Further, for most Kid-SCID diagnoses, reasonable agreement between children and parents was found. Finally, the correspondence between the Kid-SCID and the final clinical diagnosis as established after the full intake procedure, which included the information as provided by the Kid-SCID, ranged from poor to good. Results are discussed in the light of methodological issues pertaining to the assessment of psychiatric disorders in youths. The Kid-SCID can generally be seen as a reliable and useful tool that can assist clinicians in carrying out clinical evaluations of children and adolescents.

The structured clinical interview for DSM-IV childhood diagnoses (Kid-SCID): first psychometric evaluation in a Dutch sample of clinically referred youths

Objective: A recent cross-sectional study showed that maternal rejection is associated with emotional eating of obese youngsters seeking treatment, and that this relation is mediated by maladaptive emotion regulation (ER) of the youngsters. We wanted to build on this study and investigate the relation between parental rejection, maladaptive ER and emotional eating in a community sample using longitudinal data.Design: Participants were 81 youngsters between the ages of 10 and 16 years. Participants completed questionnaires assessing maternal and paternal rejection, ER strategies and emotional eating, at two time moments (M = 71 days between time moments). Latent change models were used to estimate level and change of each variable.Results: Results showed that the levels of maternal rejection, maladaptive ER and emotional eating were related. The indirect effect of the level of maternal rejection on the level of emotional eating through the level of maladaptive ER was marginally significant. On average, mat...

Computer Training of Attention and Inhibition for Youngsters with Obesity: a Pilot-study

From a clinical developmental perspective, temperament has been shown to confer vulnerability to depression among youth. High negative emotionality (NE), low positive emotionality (PE), and low effortful control (EC) have repeatedly been independently associated with youth depressive symptoms. However, far less research has examined the joint contributions of NE, PE, and EC on such symptoms. The present study builds upon previous research by examining how NE, PE, and EC jointly predict change in depressive symptoms over time among 211 youngsters (7-14 years, M = 10.7, SD = 1.81) who participated in an 8-month prospective study. Self-reported temperament and symptoms were assessed at baseline; self-reported symptoms were measured again at follow-up. Results suggest that all 3 temperamental traits need to be considered jointly in predicting change in depressive symptoms. Furthermore, results provide further support for the "best two out of three" principle. Surprisingly, results reveal that high EC might be maladaptive in the context of high emotional reactivity. Last, results show that the combination of high NE and low EC could be a possible pathway to the development of symptoms. The current study clarified how NE, PE, and EC may jointly confer risk-or protection for developing depressive symptoms during adolescence. The results highlight the need of taking into account all three temperamental traits in order to provide a more nuanced understanding of the risk for developing depressive symptoms at an early stage, as well as to provide customized care targeting temperamental vulnerability in depressed youth.
