Note. Significant p-values are bolded. SE = standard error. CT = cognitive therapy. BT = behavior therapy. CBT = cognitive behavior therapy. WSAS = Work and Social Adjustment Scale. MFI = Multidimensional Fatigue Inventory. SF-36 - Physical = SF-36 Health Survey - Physical Component. SF-36 - Mental = SF-36 Health Survey - Mental Component. “Coefficient” header applies to “Interactions” and “contrasts” header applies to “Postestimation Contrasts.” For interactions, the first treatment listed represents the reference group (e.g., for “CT vs. BT,” the reference group is CT).
