The ability of personality traits to predict im- portant life outcomes has traditionally been questioned because of the putative small effects of personality. In this article, we compare the predictive validity of personality traits with that of socioeconomic status (SES) and cogni- tive ability to test the relative contribution of personality traits to predictions of three critical outcomes: mortality, divorce, andoccupationalattainment.Onlyevidence from prospective longitudinal studies was considered. In addi- tion, an attempt was made to limit the review to studies that controlled for important background factors. Results showed that the magnitude of the effects of personality traits on mortality, divorce, and occupational attainment wasindistinguishablefrom the effectsofSES and cognitive ability on these outcomes. These results demonstrate the influence of personality traits on important life outcomes, highlight the need to more routinely incorporate measures of personality into quality of life surveys, and encourage further research about the developmental origins of per- sonality traits and the processes by which these traits in- fluence diverse life outcomes.

Principles and Practice of Sleep Medicine

Accelerometers are widely used to measure sedentary time, physical activity, physical activity energy expenditure (PAEE), and sleep-related behaviors, with the ActiGraph being the most frequently used brand by researchers. However, data collection and processing criteria have evolved in a myriad of ways out of the need to answer unique research questions; as a result there is no consensus. The purpose of this review was to: (1) compile and classify existing studies assessing sedentary time, physical activity, energy expenditure, or sleep using the ActiGraph GT3X/+ through data collection and processing criteria to improve data comparability and (2) review data collection and processing criteria when using GT3X/+ and provide age-specific practical considerations based on the validation/calibration studies identified. Two independent researchers conducted the search in PubMed and Web of Science. We included all original studies in which the GT3X/+ was used in laboratory, controlled, or free-living conditions published from 1 January 2010 to the 31 December 2015. The present systematic review provides key information about the following data collection and processing criteria: placement, sampling frequency, filter, epoch length, non-wear-time, what constitutes a valid day and a valid week, cut-points for sedentary time and physical activity intensity classification, and algorithms to estimate PAEE and sleep-related behaviors. The information is organized by age group, since criteria are usually age-specific. This review will help researchers and practitioners to make better decisions before (i.e., device placement and sampling frequency) and after (i.e., data processing criteria) data collection using the GT3X/+ accelerometer, in order to obtain more valid and comparable data.

Accelerometer Data Collection and Processing Criteria to Assess Physical Activity and Other Outcomes: A Systematic Review and Practical Considerations

This meta-analysis reviewed 126 published empirical articles over the past 50 years describing associations between marital relationship quality and physical health in more than 72,000 individuals. Health outcomes included clinical endpoints (objective assessments of function, disease severity, and mortality; subjective health assessments) and surrogate endpoints (biological markers that substitute for clinical endpoints, such as blood pressure). Biological mediators included cardiovascular reactivity and hypothalamic-pituitary-adrenal axis activity. Greater marital quality was related to better health, with mean effect sizes from r = .07 to .21, including lower risk of mortality (r = .11) and lower cardiovascular reactivity during marital conflict (r = -.13), but not daily cortisol slopes or cortisol reactivity during conflict. The small effect sizes were similar in magnitude to previously found associations between health behaviors (e.g., diet) and health outcomes. Effect sizes for a small subset of clinical outcomes were susceptible to publication bias. In some studies, effect sizes remained significant after accounting for confounds such as age and socioeconomic status. Studies with a higher proportion of women in the sample demonstrated larger effect sizes, but we found little evidence for gender differences in studies that explicitly tested gender moderation, with the exception of surrogate endpoint studies. Our conclusions are limited by small numbers of studies for specific health outcomes, unexplained heterogeneity, and designs that limit causal inferences. These findings highlight the need to explicitly test affective, health behavior, and biological mechanisms in future research, and focus on moderating factors that may alter the relationship between marital quality and health.

Marital quality and health: A meta-analytic review.

The American Academy of Sleep Medicine and Sleep Research Society recently released a Consensus Statement regarding the recommended amount of sleep to promote optimal health in adults. This paper describes the methodology, background literature, voting process, and voting results for the consensus statement. In addition, we address important assumptions and challenges encountered during the consensus process. Finally, we outline future directions that will advance our understanding of sleep need and place sleep duration in the broader context of sleep health.

Background. ICD-10 acute and transient psychotic disorder (ATPD; F23) and DSM-IV brief psychotic disorder (BPD; 298.8) are related diagnostic concepts, but little is known regarding the concordance of the two definitions.Method. During a 5-year period all in-patients with ATPD were identified; DSM-IV diagnoses were also determined. We systematically evaluated demographic and clinical features and carried out follow-up investigations at an average of 2·2 years after the index episode using standardized instruments.Results. Forty-two (4·1%) of 1036 patients treated for psychotic disorders or major affective episode fulfilled the ICD-10 criteria of ATPD. Of these, 61·9% also fulfilled the DSM-IV criteria of brief psychotic disorder; 31·0%, of schizophreniform disorder; 2·4%, of delusional disorder; and 4·8%, of psychotic disorder not otherwise specified. BPD showed significant concordance with the polymorphic subtype of ATPD, and DSM-IV schizophreniform disorder showed significant concordance with the schizophreniform subtype of ATPD. BPD patients had a significantly shorter duration of episode and more acute onset compared with those ATPD patients who did not meet the criteria of BPD (non-BPD). However, the BPD group and the non-BPD group of ATPD were remarkably similar in terms of sociodemography (especially female preponderance), course and outcome, which was rather favourable for both groups.Conclusions. DSM-IV BPD is a psychotic disorder with broad concordance with ATPD as defined by ICD-10. However, the DSM-IV time criteria for BPD may be too narrow. The group of acute psychotic disorders with good prognosis extends beyond the borders of BPD and includes a subgroup of DSM-IV schizophreniform disorder.

The concordance of ICD-10 acute and transient psychosis and DSM-IV brief psychotic disorder

Brief and acute psychotic disorders with a short duration and a generally good prognosis have long intrigued psychiatrists. Although they are included in internationally accepted diagnostic systems, understanding of these disorders remains minimal. This book is the first comprehensive overview of the clinical features, biology, course and long-term outcome of brief and acute psychoses. The authors review the world literature on the topic and they also present data from their own longitudinal study - the most complete investigation of this group of disorders so far conducted. The book concludes with considerations of the nosological status of brief and acute psychoses and their impact on our understanding of the continuum of psychotic and affective disorders.

Acute and Transient Psychoses

Objective: We prospectively investigated a sample of 42 patients with acute and transient psychotic disorder (ATPD) as defined by the 10th revision of the International Classificati

Concordance of Acute and Transient Psychoses and Cycloid Psychoses

This paper reviews the conceptual history of brief and acute psychoses. As psychotic disorders of usually dramatic symptomatology but nevertheless with a usually benign course, brief and acute psychoses have the air of a paradox. Thus, they have posed specific problems in regard to nosology, diagnostics and aetiology. Despite a strong convergence of the descriptive elements, the historical concepts of brief and acute psychoses have yielded different answers to the questions raised. Kahlbaum and Kraepelin set the stage on which brief and acute psychoses appeared "atypical". The concept of "bouffee delirante" used degeneration theory as a background for nosological and aetiological allocation. Similarly, the concepts of cycloid psychoses, reactive (psychogenic) psychoses, emotional psychoses and atypical psychoses have provided diverging but interrelated ways to delineate brief and acute psychoses, to determine their nosological status and to explain the coexistence of severe disorder and favourable prognosis. Modern classifications, namely the acute and transient psychotic disorder of ICD-10 and the brief psychotic disorder of DSM-IV, reflect the varied history of the concept.
