Which of the following is true of experimental counseling process designs?

A) They are characterized by randomization of clients to the levels of independent variables.
B) They are viable for all process variables due to the feasibility of control of such variables during the counseling process.
C) They are characterized by the observation of the change in dependent variables in real-life situations.
D) They are inherently free of research allegiance bias which may confound the results.

Experimental counseling process designs involve randomization of clients to different levels of independent variables in order to determine the effect of these variables on the dependent variable. This is a key characteristic of experimental designs. Option B is not true, as not all process variables can be controlled during counseling sessions. Option C is more characteristic of a quasi-experimental design, where the intervention is observed in real-life situations. Option D is also not true, as research allegiance bias can still occur in experimental designs.
