Selected Psychosocial Measures for Each Group at Baseline and Follow-Up. Two measures are presented for illustrative purposes to show observed patterns of change over time across groups. a) Pennebaker Inventory of Limbic Languidness (PILL) scores, in which higher scores indicate greater endorsement of somatic symptoms; b) Perceived Stress Scale (PSS) scores, where higher scores indicate greater perceived stress. Open diamonds (⋄) reflect Baseline values and closed circles (●) reflect Follow-Up values. No statistical inference testing was performed on these data, as our statistical approach modeled the change scores as presented in Tables 2, 3 and 4.
