The Photographic Affect Meter, a novel tool for frequent, unobtrusive measurement of affect.
The assessment of affect is critical for anyone trying to understand human behavior. But there is a problem: affect as a state is frequently changing and difficult to recall and express, yet in research, we typically only assess it via a single questionnaire at the end of a study. So we developed PAM, the Photographic Affect Meter, a novel tool for measuring affect, in which u of photos the one which best suits their current mood. PAM is built in the Ecological Momentary Assessment (EMA) tradition, intended for frequent and unobtrusive measurement.
Our findings indicate that PAM – which takes seconds to complete and is designed to run on modern mobile phones and mobile computing devices – demonstrates strong construct validity across two studies and is very well suited for frequent sampling in context. This work provides a tool to researchers in need of frequent assessment of affect and guidance to others interested in developing similar measurement tools.
