Data analysis
Data analyses were generally the same as in Study 1, including descriptive statistics, inter-correlations, examination of intervention implementation, and the use of repeated measures ANOVAs to examine intervention effects on hiking frequency, stress, and sleep duration, with primary models including all available data from all participants who engaged with any study activities after baseline (n = 47). We repeated analyses to see whether primary results were consistent when: adjusting for household size, repeating analyses for all randomized participants (n = 51), and operationalizing the predictor as those who engaged in the intervention versus those who did not, rather than assigned study group. Finally, in this study, we also explored study group differences in sleep quality at midpoint and post-intervention.
