Currently, I am trying to design a mixed methods research with emphasis at the quantitative part to explore the factors influencing counselling self-efficacy of counselling trainees from various Universities in Greece. My intent is to use two counselling self-efficacy questionnaires (one for Career Counselling Self-Efficacy, O'Brien et al., 1997 and another one for Counselling Self-efficacy, Larson et al., 1992) as well as a questionnaire for the demographics in order to test the relationships mentioned in the bibliography among variables such as length of past experience, training and practicum and trainees' self-efficacy. Additionally, I would like to see which is the role of core self-evaluations with a single instrument (Judge et al., 2003).
On the other hand, in the qualitative part, I would like to take several interviews from a small sample of the participants, maybe 15, in order to test if the four sources which form self-efficacy (mastery experiences, vicarious learning, verbal persuasion, emotional state) suggested by Bandura would apply in counselling trainees.
What would you do in this case? Do you find a mixed methods design suitable for this kind of research purpose? Would it be a good idea to have a sample of trainees in career counseling (my specialty) and another one for trainees in counselling psychology?
I am looking forward to your views and ideas.
