A condition defined by at least two weeks of persistently low mood or loss of interest, together with changes in sleep, appetite, energy, concentration and self-worth, causing significant impairment.

The property that an instrument measures the same construct in the same way across groups or across time. Without it, a difference between groups may reflect how they interpret the items rather than any real difference.
Memory Reconsolidation
The finding that retrieving a consolidated memory can return it to an unstable state in which it must be restabilised, opening a window in which it can be modified or weakened.
Motivational Interviewing
A collaborative conversational method for strengthening a person's own motivation for change, by drawing out and reinforcing the arguments for change that they make themselves rather than supplying them.
