Computerized ecological momentary assessment (EMA) is widely accepted as a "gold standard" method for capturing momentary symptoms repeatedly experienced in daily life. Although many studies have addressed the within-individual temporal variations in momentary symptoms compared with simultaneously measured external criteria, their concurrent associations, specifically with continuous physiologi...

In studies using ecological momentary assessment (EMA), or other intensive longitudinal data collection methods, interest frequently centers on changes in the variances, both within-subjects and between-subjects. For this, Hedeker et al. (Biometrics 2008; 64: 627-634) developed an extended two-level mixed-effects model that treats observations as being nested within subjects and allows covariat...

Pregnancy is thought to diminish a woman’s appraisals of and affective responses to stressors. To examine this assumption, we used an electronic diary and an ecological momentary assessment strategy to record women’s (n=85) experiences of positive and negative affect five times each day over two days within each trimester of pregnancy. Women also completed the Edinburgh Postnatal Depression Sca...

OBJECTIVES To prospectively characterize and compare daytime symptoms in primary insomnia (PI) and good sleeper control (GSC) subjects using ecological momentary assessment; to examine relationships between daytime symptom factors, retrospective psychological and sleep reports, and concurrent sleep diary reports. METHODS Subjects included 47 PI and 18 GSC. Retrospective self-reports of daytim...

BACKGROUND Affect instability is a core symptom of borderline personality disorder (BPD). Ecological momentary assessment allows for an understanding of real-time changes in affect in response to various daily stressors. The purpose of this study was to explore changes in affect in response to specific stressors and coping strategies in subjects with BPD utilizing ecological momentary assessmen...

Many psychologists collect multitrait-multimethod (MTMM) data to assess the convergent and discriminant validity of psychological measures. In order to choose the most appropriate model, the types of methods applied have to be considered. It is shown how the combination of interchangeable and structurally different raters can be analyzed with an extension of the correlated trait-correlated meth...

14 The elemental (C, N and P) and isotopic (δ 13 C, δ 15 N) content of leaves of the seagrasses 15 Thalassia testudinum, Halodule wrightii, and Syringodium filiforme were measured across a 16 10,000 km 2 survey of the seagrass communities of South Florida in 1999 and 2000. Trends at 17 local and broad spatial scales were compared to examine interspecific variation in the seagrass 18 characteris...
