I scored 3 and I am programming more or less 84+ hours a week, yes I am a code junkie and I love it. I would increase my time but I have a cat that demands attention and I also do exercise and all my own cooking / cleaning.
If you asked this survey before 2010 I probably would have scored really high. Like others have mentioned it is flawed, I don't like the way it is worded, others have already covered why. Also there is a difference between anxiety and depression, some of the things you have mentioned fall under one only.
I scored 3 on "I have lost interest in other people", sadly the internet has put me off people, I can manage trolls (I was one for 10 years), I can manage spammers and I can manage egotistical people but one thing I cant manage is the enormous amount of negativity that is getting worse and worse daily. As a result ALL media related shit has been blocked, I now live a life where I don't hear about any news at all and more importantly I never hear about which triangle shaped eyeball is trying to take over the world or which government people think are killing its own citizens or which race is the source of all problems or any of the other crap you hear over and over. If you want to know what depressed me in the past, it was listening to 'those' types of people and reading the negative trash in the media that made it look like everything and everyone was bad; I also don't watch TV or movies either but that is simply because I never have time.
