The main outcome measure was the difference in mean score severity rating of depression and anxiety symptoms on the CES-D and Zung questionnaires between groups at the time of embryo transfer.
Both predictions were supported.When controlling for shared method bias amongst positively worded items, a single factor well-being/depression continuum underlies the CES-D. Baseline levels on this continuum are found to have near linear relationships with changes in anxiety symptoms, aggression, and substance misuse over time, demonstrating that moving from depression to well-being on the CES-D provides an equal decrease in risk for several other psychological problems irrespective of position on the continuum.
