The association between life satisfaction and health-promoting behavior is likely to be bidirectional, but may partly account for the relationship between positive states and good health.

The impact of social isolation on cardiovascular disease risk may be mediated through stress-related dysregulation of cardiovascular, metabolic, and neuroendocrine processes.

Measurement of affective states in everyday life is of fundamental importance in many types of quality of life, health, and psychological research. Ecological momentary assessment (EMA) is the recognized method of choice, but the respondent burden can be high. The day reconstruction method (DRM) was developed by Kahneman and colleagues (Science, 2004(Science, , 306, 1776(Science, -1780 to assess affect, activities and time use in everyday life. We sought to validate DRM affect ratings by comparison with contemporaneous EMA ratings in a sample of 94 working women monitored over work and leisure days. Six EMA ratings of happiness, tiredness, stress, and anger/frustration were obtained over each 24 h period, and were compared with DRM ratings for the same hour, recorded retrospectively at the end of the day. Similar profiles of affect intensity were recorded with the two techniques. The between-person correlations adjusted for attenuation ranged from 0.58 (stress, working day) to 0.90 (happiness, leisure day). The strength of associations was not related to age, educational attainment, or depressed mood. We conclude that the DRM provides reasonably reliable estimates both of the intensity of affect and variations in affect over the day, so is a valuable instrument for the measurement of everyday experience in health and social research.

Aims Eating disorders are serious psychiatric disorders with high rates of morbidity and mortality. Early intervention can improve treatment outcomes and reduce disruption to psychosocial development. However, early intervention is not well established in the eating disorder field. First episode rapid early intervention for eating disorders (FREED) was developed to address barriers to early, effective eating disorder treatment in emerging adults aged 16 to 25 years. Since 2014, FREED has progressed from a single‐site research project to an evidence‐based care approach in nine eating disorder services. This paper aims to summarize key learning from the scaling of FREED to date, with attention to how this learning may generalizes to other models of care. Methods We describe the development, scaling and implementation of FREED with reference to the RE‐AIM (reach; effectiveness/efficacy; adoption; implementation; maintenance) framework. We also summarize challenges and learning in each of the RE‐AIM domains. Results FREED has demonstrated real‐world validity across diverse clinical contexts, geographical regions and populations. Key outcomes are seen for each of the RE‐AIM domains. Conclusions FREED provides an example of effective, non‐commercial scaling of an early intervention eating disorder care pathway. This work is likely to be particularly relevant to others looking to scale‐up early intervention models and for those working in secondary and tertiary mental health settings.
