Is there any physiological value or index that show us a stress or anxiety level? For example in an experimental reseach, when we want to find out computer games effect on stress, depression or anxiety, How can we detect these disorders level by using with physiological indicators?
There are many investigations in this regard, in daily clinical practice it is used within the neurobiofeedback method
Dear Huseyin,
These measures of the responses of the sympathetic branch of the autonomic nervous system, such as GSR, mainly give immediate indicators of momentary variability in arousal, but it sounds like you are more interested in more prolonged and durable states of increased levels of anxiety and depression? If so, I would recommend you look into Heart Rate Variability as a possible psychophysiological indicator.

Ole André Solbakken, yes i'm interested more durable states. Actually i plan to measure participants' depression, stress and anxiety levels with questionnaire. Participants will play a game for 6 weeks and 2 or 3 times a week. i will analyse with pre and post test. i hope to see effect of this game and variation levels of disorders. So i need to support these finding with objective indicators. i haven't found how can i do that. i think i can use average heartbeat rate's variation. I can follow up this variation weekly. But i am not sure that how can i use GSR. Maybe i collect GSR data before and during the game play and this variation maybe help me to interpret findings. Is it proper to do it this way? This is first time i am in this kind of research and I am trying to build the research correctly. and thanks for your answer.
Yes, stress level can be measured by these measures. However, it might be that stress level can be detected to one individual based on high heart beat rate while in the other, the index would be the galvanic responce etc.
Dear Huseyin,
I concur with Ole André that heart rate variability (HRV) is a good indicator of long-term stress reactivity. However, HRV is not a single metric (like calculating statistical variance of heartbeat periods, for instance); it includes rather wide variety of metrics in both time and frequency domain, summary of which can be found here:

Hope this helps a little. Best!

Michael Batakis and Tomáš Dominik thanks for your answers.
its seems HRV is proper for me. What about EEG? Please everyone feel free to share some basic applications and articles about these subject. It would be stimulating for me.
Dear Huseyin,
Check out some of the work of clinical neuropsychologist and professor Stein Andersson at the University of Oslo, he does a lot of interesting stuff in this area.
