McGuire, 44, of Eaglesham, East Renfrew-shire, is accused of assaulting her husband Derek Mitchell at the family home on December 8 last year.
She was due to stand trial at Paisley Sheriff Court next month.
But yesterday her lawyer Iain Fleming told Sheriff Susan Mitchell that McGuire had been examined by consultant psychiatrist Dr Jacqueline Anderson.
Mr Fleming said: "She has been diagnosed as having a major depressive disorder."
McGuire was not present in court having been excused at an earlier hearing.
She denies behaving in a threatening or abusive manner towards her husband by shouting at him, pursuing him, forcing open a bathroom door and placing him in a state of alarm.
She also denies striking him on the body, knocking him down a flight of stairs, repeatedly punching and kicking and stamping on his head and body.
It is also alleged she threw household articles at him and attacked him with a shoe.
Defence lawyer Mr Fleming asked for the case to be reviewed in three months time.
But depute fiscal Susan Brown asked Sheriff Sinclair to continue the case until September 4.
Sheriff Sinclair agreed to this and excused McGuire having to attend court.
McGuire, who is charged under her married name of Susan Mitchell, is currently suspended by Radio Clyde pending the outcome of this case.
She married accountant Derek in 2010.
