Regression coefficients are presented for an increase of one standard deviation (SD) for continuous variables (resilience: SD = 6.09, social support: SD = 5.93, perceived organizational support: SD = 11.65). 12-month responders had a mean score of 4.69 ± 3.45 on the depression subscale of the HADS, n = 396. Psychiatric history was considered in the stepwise but not selected. The final model is therefore the one above
