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...

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...

This paper presents the results of a mixed-methods study examining adaptation strategies that property owners in low-income, rapidly urbanizing areas in Malawi adopt to address the limitations of pit latrines, the most common method of disposing human excreta. A particular challenge is lack of space for constructing new latrines as population density increases: traditional practice has been to ...

In our research, we are examining how pervasive continuous sensing and targeted ecological momentary assessment can be used to unobtrusively collect stress data, and we are designing personal health informatics that can aggregate and visualize these stress data over time and for different audiences. In this position paper, we describe our recent and ongoing efforts in this area and articulate s...

Ecological sanitation (Ecosan) is a relatively new concept being promoted in many developing countries to improve sanitation coverage and recycle nutrients in excreta for agricultural production. We conducted a cross-sectional study in Kabale municipality, western Uganda to determine the coverage of Ecosan and factors affecting its uptake. A total of 806 respondents were interviewed, randomly s...

INTRODUCTION The objective of this study was to determine contextual antecedents to smoking among Korean American emerging adult (KAEA) smokers using ecological momentary assessment. Based on extant theory and data documenting the importance of negative affect (NA) and social context, we examined the extent to which being with friends and NA independently and concomitantly were associated with ...

OBJECTIVES This study focused on lapse shortly after an attempt to quit smoking. Ecological momentary assessment (EMA) studies have mapped real-time situational factors that induce lapses in everyday life. However, the possible role of nonsmoking intention is disregarded in the dynamic context of daily life, whereas intention plays a key role in behavior change and shifts during smoking cessati...

The limitations of paper-and-pencil self-monitoring (PM) are leading to the use of more sophisticated techniques. PM was compared with cellular phone monitoring (CM) to collect ecological momentary assessment data on alcohol use. Twenty social drinkers were randomly assigned to the 2 groups, and their drinking was monitored for 14 days. PM participants recorded data on cards. CM participants ca...
