Registered outcomes7
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Daily Energy Intake: Total Daily Intake | 5 months | Energy intake during breakfast, lunch, dinner, and evening snacks of each day 7 testing day (separated by 3-4 weeks) will be measured. |
| Secondary | Perceived Fullness | 5 months | Questionnaires assessing fullness will be completed throughout each of the 12-hour testing days (which are separated by 3-4 weeks). The questionnaires contain validated visual analog scales (VAS) incorporating a 100 mm horizontal line rating scale for each response. The scale is 0 to 100mm. The questions are worded in the following manner "how strong is your feeling of" with anchors of "not at all" (indicated at 0 mm) to "extremely" (indicated at 100 mm). All measures are reported at area under the curve for 0 to 630 min. |
| Secondary | Reaction Time as a Measure of Cognitive Performance Assessed Using the Stroop Test | 5 months | Cognitive function will be assessed during each of the 12-hour testing days using CNS Vital Signs, a validated computerized assessment. This system contains a core battery of tasks. Reaction Time is the outcome of interest measured with the Stroop Test. In the first part, the words RED, YELLOW, BLUE, \& GREEN (printed in black) appear at random on the screen, \& the participant presses the space bar as soon as the test subject sees the word. In the second part, the words RED, YELLOW, BLUE, \& GREEN appear on the screen, printed in color. The participant is asked to press the space bar when the color of the word matches what the word says. In the third part, the words RED, YELLOW, BLUE, \& GREEN appear on the screen, printed in color. The participant is asked to press the space bar when the color of the word does not match what the word says. Reaction time is in milliseconds. |
| Secondary | Perceived Alertness | 5 months | Alertness will be assessed during each of the 12-hour testing days (which are separated by 3-4 weeks) using the Profile of Mood States 2nd Edition (POMS2) with sub-categories of perceived vigor. POM2 is a self-report measure that allows for the quick assessment of transient, fluctuating feelings, and enduring affect states. There are 35 items. Items are rated on a 5-point Likert scale ranging from 0 (not at all) to 4 (extremely). The Alertness (Vigor-Activity) scale score indicates the extent to which individual felt alert (vigorous and/or energetic); the higher are her positive feelings and/or energy, the greater is her score (i.e., a low score indicates relatively fewer positive feelings and/or low energy). Ratings on this scale yielded a T-score of 25 (95% CI =18-32), which is ranked at the 1st percentile, and falls within the Very Low score range. The T scores were then used to calculate area under the curve. |
| Secondary | Perceived Hunger | 5 months | Questionnaires assessing hunger will be completed throughout each of the 12-hour testing days (which are separated by 3-4 weeks). The questionnaires contain validated visual analog scales (VAS) incorporating a 100 mm horizontal line rating scale for each response. The scale is 0 to 100mm. The questions are worded in the following manner "how strong is your feeling of" with anchors of "not at all" (indicated at 0 mm) to "extremely" (indicated at 100 mm). All measures are reported at area under the curve for 0 to 630 min. |
| Secondary | Perceived Prospective Food Consumption | 5 months | Questionnaires assessing prospective food consumption will be completed throughout each of the 12-hour testing days (which are separated by 3-4 weeks). The questionnaires contain validated visual analog scales (VAS) incorporating a 100 mm horizontal line rating scale for each response. The scale is 0 to 100mm. The questions are worded in the following manner "how strong is your feeling of" with anchors of "not at all" (indicated at 0 mm) to "extremely" (indicated at 100 mm). All measures are reported at area under the curve for 0 to 630 min. |
| Secondary | Perceived Desire to Eat | 5 months | Questionnaires assessing desire to eat will be completed throughout each of the 12-hour testing days (which are separated by 3-4 weeks). The questionnaires contain validated visual analog scales (VAS) incorporating a 100 mm horizontal line rating scale for each response. The scale is 0 to 100mm. The questions are worded in the following manner "how strong is your feeling of" with anchors of "not at all" (indicated at 0 mm) to "extremely" (indicated at 100 mm). All measures are reported at area under the curve for 0 to 630 min. |
