Note. One participant did not complete the affect assessment at T1 resulting in an analytic sample of 106 students at T1 and 107 students at T2. Stressful life events was only assessed at T2. Composite score ranges, based on standard scoring procedures, are as follows: positive and negative affect (10–50), stressful life events (0–1466), sleep quality (0–21), food security (0–3). For sleep and food security measures higher scores indicate poorer sleep or more food insecurity, respectively. Stressful life events scores ≤150 are classified as a relatively low amount of life change and a low susceptibility to stress-induced health breakdown, scores between 151 and 299 are classified as a 50% chance of health breakdown in the next 2 years, scores ≥300 are classified as an 80% chance of health breakdown in the next 2 years. For correlations, correlations at T2 (i.e., during COVID-19 stay-at-home order) are below the diagonal and correlations among the change scores from T1 to T2 are above the diagonal. Change scores are calculated as T2-T1.
