^*Sample sizes for analyses reflect available data from study completers at time 2 (n = 22).

^†Stress Visual Analogue Scale (range 0–10).¹⁴ Single item scale. 0 indicates no perceived stress and 10 indicates extreme stress.

^‡MOCs-A: Measure of Current Status – Part A (range 0–52). Sum score of 13 items with ranges 0–4. Higher scores reflect greater perceived ability to cope with stress. Composite score consists of four subscales reflecting different aspects of coping: awareness of tension, ability to relax at will, ability to assert needs, and coping confidence.^20–21 The MOCS-A has been successfully used to document change in participants’ ability to decrease the stress response.²¹

^§CES-D: Center for the Epidemiological Studies of Depression Short Form (range 0–30). Sum of 10 items with ranges of 0 – 3 measuring symptoms of depression over the past week. Items 5 and 8 are reverse scored. Higher scores reflect higher levels of depressed mood; score of 10 or higher is considered depressed.^15–16

^¶GAD-7: Generalized Anxiety Disorder 7-item scale (range 0–21). Sum score of 7 individual items with ranges of 0–3. Higher scores indicate more symptoms of anxiety; cutoff score of 10 is considered to reflect moderate levels of anxiety.¹⁷

^λIUS-12: Intolerance of Uncertainty Scale – Short Form (range 12–60). Sum score of 12 items with ranges 0–5 that are used to measure of intolerance of uncertainty. Higher scores reflect greater intolerance of uncertainty. Composite score is comprised of two subscales measuring avoidance of uncertainty (inhibitory intolerance of uncertainty; range 0–35) and a desire for predictability (prospective intolerance of uncertainty; range 0–25).^18–19

^▫FSI: Fatigue Symptom Inventory – Fatigue Disruption Index (range 0–70). Fatigue Symptom Inventory is 14-item self-report measure that assesses the severity, frequency, and daily pattern of fatigue as well as its perceived interference with quality of life. Fatigue disruption index consists of sum of 7 items (questions 5–11) with ranges 0–10; higher scores reflect higher perceived disruption.^22–23
