ListOutcomeTime frameDescriptionSource
PrimaryChange in affect from baseline up to 48 hours post-walkDay 1 to Day 3Positive and Negative Affect Schedule (PANAS)ClinicalTrials.gov
SecondaryChange in Executive FunctionsThe Stroop test will be administered at 2 time points: 1) before the walk (between 9:45-10:30); 2) after the walk (between 11:30-11:50)
The stroop color word test is a widely used task to assess selective attention and inhibitory control. In the first block of this task (A), color words (red, blue, yellow, green) printed in black ink are presented in random order and participants are asked to read out loud the words. In the second block (B), solid color patches in one of the same four colors are shown and participants name the colors. Finally, in the third block (C), color words are printed in an incongruous ink color and participants must name the ink color (e.g. GREEN \[typed in red\]; response = red). Participants are asked to complete each block as quickly and accurately as possible and the time to complete each trial is calculated and averaged for each block. An interference score is calculated as followed: C - \[(A + B) /2\].

SecondaryChange in suicidal IdeationsDay 1
Severity of Suicidal Ideations The severity of current suicidal ideation will be assessed with three items derived from a prior study of momentary assessment of suicidal risk: "How intense is your desire to kill yourself right now"?; "How strong is your intention to kill yourself right now"?; "How strong is your ability to resist the urge to kill yourself right now"? Each item is scored on a scale from 0 (not strong \[intense\] at all) to 4 (very strong \[intense\]).

SecondaryChange in depressive symptomsDay 1 to Day 2
The Beck Depression Inventory (BDI-II) The BDI is a widely used 21-item depression inventory with good internal consistency (α = .93 in the current sample) and validity. Items are answered on a 4-point scale from 0 to 3.

SecondaryChange in ruminationDay 1
The Rumination-Reflection Questionnaire (RRQ) The RRQ is a 24-item self-reported questionnaire assessing both self-rumination and self-reflection, 57 with 12 items corresponding to each subscale. Participants rate the degree to which they engage in self- rumination (e.g. "sometimes it is hard for me to shut off thoughts about myself") and self-reflective thoughts (e.g. "I love to meditate on the nature and meaning of things") on a Likert scale ranging from one (strongly disagree) to five (strongly agree)

SecondaryChange in irritabilityDay 1 to Day 3
The Brief Irritability Test (BITe): The BITe is a 5-item self-report measure of irritability that is suitable for use among men and women. Participants respond to statements using a 6-point Likert scale ranging from Never to Always. Items include the following five statements: "I have been grumpy"; "I have been feeling like I might snap"; "Other people have been getting on my nerves".
