I would get the degree in CSD if you are really interested in Speech Pathology. I have a BA in psychology -almost every job I applied to out of college wanted a degree in psychology or similar field. I think you can sub a CSD major for a psych one but not the other way around. Also, SLP master programs all have different pre-requisites -but if you have a major in CSD you don't have worry about it. I'm doing a post-bacc now and the 4 grad programs I'm applying to all have different requirements for non-majors. Also, you can apply to a Master's program in counseling, social work, etc. with a CSD major if you change your mind. In my opinion a double major isn't necessary. From life experience (I'm 42) I can tell you most employers just look at the degree and don't really care about the major.
