Thanks Pam! Please use this link if you are interested in these focus group studies.

We are now recruiting participants for a series of upcoming focus groups that will discuss the impacts of AI on health and well-being. If you or any friends/colleagues are interested, please visit the study site:

Fire everyone and close the doors. This crap is just so infuriating and a slap in the face for anyone trying to do honest scientific work.

Do You Agree? Do You Strongly Agree? The Effect of the Number of Response Categories on Response Processes and Verification of Substantive Hypotheses Abstract. This study investigates how the number and labeling of response categories in survey scales affect respondent behavior, psychometric properties,
