Registered outcomes29
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Core temperature (Peak) during daylong exposure to indoor overheating | End of 6 hour daylong exposure | Peak visceral temperature (15 min average) during exposure. Visceral temperature is measured continuously throughout the 6 hour exposure to the simulated indoor overheating. A 0.2°C between-group difference will be considered the smallest physiologically meaningful effect. |
| Secondary | Profiles of Mood States (POMS) during daylong exposure to indoor overheating | At the start (hour 0) and end of 6 hour daylong exposure | Potential changes in mood (7 subscales of mood: tension, anger, depression, fatigue, confusion, vigor and esteem related affect). The POMS-40 is a validated, self-administered questionnaire that examines seven distinct aspects of mood state across two positive subscales (Esteem-Related Affect, and Vigor) and five negative subscales (Fatigue, Tension, Confusion, Anger, and Depression), which are described across 40 distinct adjectives. For each individual item, participants were asked to describe "how you feel right now" by responding using a 5-point Likert scale (0 = "Not at all", 1 = "A little", 2 = "Moderately", 3 = "Quite a lot", or 4 = "Extremely"). The values of items associated with a specific subscale (e.g., Fatigue) were summed to calculate its score. |
| Secondary | Environmental Symptoms Questionnaire (ESQ) during daylong exposure to indoor overheating | At the start (hour 0) and end of 6 hour daylong exposure | Self-reported environmental reactions and medical symptomatology associated with prolonged heat exposure. The ESQ-IV is a validated 68-item, self-administered questionnaire that has been used successfully in identifying symptomatology during exposure to a wide variety of environmental conditions, including heat exposure. Participants are asked to assess and described "how you have been feeling today" by responding to each item using a 6-point Likert scale (0 = "Not at all", 1 = "Slight", 2 = "Somewhat", 3 = "Moderate", 4 = "Quite a bit", or 5 = "Extreme"). Total Symptom Score was calculated from this data by taking the sum of the intensity ratings from all 68 individual items using reverse scores for the three positive items from the list ("I Felt Good", "I Felt Alert", and "I Felt Wide Awake"). |
| Secondary | Perceived exertion scale during daylong exposure to indoor temperature limit. | At the start (hour 0) and end of 6 hour daylong exposure | Perceived exertional assessed via a visual analog scale ("How hard are you working?") ranging from "no exertional at all" to "maximal exertion" |
| Secondary | Activity levels during daylong exposure to indoor overheating | End of 6 hour daylong exposure | Activity levels assessed via a wearable monitor (Actical) containing an accelerometer worn on the wrist and hip. |
| Secondary | Feel good scale during daylong exposure to indoor overheating | At the start (hour 0) and end of 6 hour daylong exposure | Feel good scale assessed via a visual analog scale (How good do you feel?) ranging from "very good" to "very bad" (midpoint: neutral) |
| Secondary | Thirst sensation scale during daylong exposure to indoor overheating | At the start (hour 0) and end of 6 hour daylong exposure | Thirst sensation assessed via a visual analog scale ranging from very, very thirsty to not thirsty at all. |
| Secondary | Thermal comfort scale during daylong exposure to indoor overheating | At the start (hour 0) and end of 6 hour daylong exposure | Thermal comfort assessed via a visual analog scale ("How comfortable does your body temperature feel?") ranging from "very uncomfortable" to "comfortable". |
| Secondary | Thermal sensation 2 scale during daylong exposure to indoor overheating | At the start (hour 0) and end of 6 hour daylong exposure | Thermal sensation assessed via a visual analog scale ("How do you feel?") ranging from "hot" to "cold"(midpoint: neutral) |
| Secondary | Thermal sensation scale during daylong exposure to indoor overheating | At the start (hour 0) and end of 6 hour daylong exposure | Thermal sensation assessed via a visual analog scale (How hot do you feel?) ranging from "extremely hot" to "neutral". |
