I agree with this post. If you are pursuing a PhD, a low GPA can hurt your application largely because you'll be screened out and won't reach final stages of the review process. Clinical psychology programs have hundreds of applications, and use metrics like GPA, GRE, etc. to filter. A master's degree could help "override" your undergrad GPA, and help you bypass these filters. Some advice I received that has been helpful: look at your application like data. The more data you have that suggests you're a good candidate (e.g. high GRE, research experience), the higher your chances. Try to make your GPA the outlier, and the rest of your application data show your true potential.
