I noticed that The Depressed Moose had one of those depression questionaires. I don’t mean magazine ones that have little or no intelligence behind them, no a real doctors tick sheet.

You answer a few questions, each answer is worth 0-3 points. If you get a higher score, you should probably be talking to a doctor.
Would be great if me sharing this form helped just 1 person avoid a breakdown, catching it whilst its still slight or moderate depression rather than  my slightly insane little meltdown.

So here you go, utterly stolen from Moose, but with permission, so its all good.
I’d recommend opening the file (.pdf) and then using Calculator on your computer screen, no effort.

This Form Could Change a Life

The PHQ9 Questionnaire is used by GP’s to asses your depression. If you suspect that you or, someone you know, has depression have a look at the form by clicking the link to load it and answer the questions HONESTLY.
It is only a starting point but if your answering “More than Half” and “Nearly Every Day” to most of the questions then you need to see your Doctor.
FORM IS HERE, CLICK ME!
No crime in having depression, it is not a sign of weakness so don’t be afraid to talk to someone about it!

PHQ-9 Depression Severity
This is calculated by assigning scores of 0, 1, 2, and 3, to the response categories of “not at all,” “several days,” “more than half the days,” and “nearly every day,” respectively. PHQ-9 total score for the nine items ranges from 0 to 27. In the above case, the PHQ-9 depression severity score is 16 (3 items scored 1, 2 items scored 2, and 3 items scored 3). Scores of 5, 10, 15, and 20 represent cutpoints for mild, moderate, moderately severe and severe depression, respectively. Sensitivity to change has also been confirmed.
