The difference between “complete” OBN and non-complete in effect size (cohen's d > 0.8 = large effect); the mean change of each group; and the response rates (%) of each group for depression questionnaires only. BDI, Beck Depression Inventory; DAS, Dysfunctional Attitudes Scale (measures trait pessimism); HAM-D, Clinician rated Hamilton Depression Rating scale; LOT-R, Life Orientation Test Revisited (measures optimism); QIDS-SR, Self-Reported Quick Inventory of Depressive Symptoms; SHAPS, Snaith-Hamilton Pleasure Scale; STAI, Spielberger's Trait Anxiety Inventory.
