We have found Ryff's scale most useful in various studies. Original information follows

Ryff, C. D. and Keyes, C. L. M. (1995). The structure of psychological well-being

revisited. Journal of Personality and Social Psychology, 69, 719 – 727.

Ryff, C. D. (1989). Happiness is everything, or is it. Explorations on the meaning of

psychological well-being. Journal of Personality and Social Psychology, 57,

1069 – 1081.

Ryff, C. D. and Keyes, C. L. M. (1995). The structure of psychological well-being

revisited. Journal of Personality and Social Psychology, 69, 719 – 727.

I would check out some of these articles. There are a lot of changes that can occur. Psychophysiology is an interesting field too.
