Ecological Momentary Determinants of Sedentary Behavior

29. oktober 2019 opdateret af: Matthew P Buman, PhD, Arizona State University

TranSITion: Ecological Momentary Determinants of Sedentary Behavior

A two phase trial to understand the personal, behavioral, environmental, and contextual factors that underpin sedentary behavior and to systematically test a series of contextual prompt characteristics that may lead to subsequent change in sedentary behavior.

Detaljeret beskrivelse

Phase 1: This is an observational study that will utilized Ecological Momentary Assessment, to determine which personal (e.g. fatigue, mood, and stress level), behavioral (e.g. watching TV, working at desk, and eating meals), environmental (e.g. being at home or work, time of the day, and weather) and contextual factors were associated with sedentary behavior. Three EMAs per day will be sent randomly sent to participants on weekdays (Monday to Friday), for four consecutive weeks (total of 20 days). During these days, participants will also wear an activPAL device to objectively measure sedentary behavior. The purpose of the study is to identify the combination of factors most likely to precede and proceed short (<30 min) and long (≥30 min) bouts of sedentary behavior.

Phase 2: A micro-randomized trial will be used to evaluate the efficacy of an email-based prompt to elicit a proximal effect (e.g., a postural response defined as a transition from seated to standing or seated to moving within 5 minutes to interrupt prolonged sitting) compared to a no prompt condition. A secondary aim of this study is to determine whether prompts that encourage standing are more likely to elicit a response than those that encourage moving. An exploratory aim is to examine whether varying the content of the stand or move prompt to include combinations of short term goals and employer approval, influence the magnitude of response.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Prompt
An email based prompt was sent- containing either a stand or move message. Exploratory variations of the prompt were designed to include the addition of a goal e.g., stand for the next 5-minutes, and/or employer support e.g., PTS says "stand for the next 5 minutes".
Adfærdsmæssigt: Prompt sent
Ingen indgriben: No Prompt
Prompt delivery was sequentially randomized to be sent (ST) or not sent (NST) to all participants (probability of 0.5), at eight decision points per day (between 9am and 5pm), to achieve a total of 3200 randomizations across participants (160 per participant). Therefore 50% of the time, no prompt was sent.

Tidsramme
Momentary affective state (4-item Likert Scales)
Tidsramme: 20 days
Affective states will be assessed using an ecological momentary survey based on the Positive and Negative Affect Scale (4-point Likert scale ranging from "not at all" to "extremely") (Range: 1-4) questionnaire. The ecological momentary assessment questions were designed to assess a range of contextual information (i.e., current office location, posture, social interaction) and physical and emotional feeling states (i.e., calmness, energy, happiness, stress, sadness, pain level, productivity, and willingness to stand/move). Each of these questions will be evaluated individually andaveraged to evaluate positive (i.e., calmness, energy, happiness) and negative (i.e., sadness and stress) affective states. An open-source app (Personal Analytic Companion App) will be used to deliver EMA questions randomly throughout a participant's workday. This will allow us to measure self-reported levels of positive or negative affect.
