How to rank factors of a confirmatory factor analysis?

#1
Hey there,

within my current study I would like to determine the importance of different behavioral intentions. Since behavioral intentions are latent constructs I applied the theory of planned behavior in order to measure those intentions. Now I got 5 different factors, each representing one specific intention. In the next step I would like to compare those intentions in order to determine the most important intention.

My question hereby is how to best derive a ranking order from those factors? Is calculating a factor score by means of either averaging or adding up all factor loadings per factor and subsequently ranking the individual factor scores by size an appropriate approach?
