    Area of Science:

    • Psychology
    • Human-Computer Interaction
    • Perception

    Background:

    • Existing body image measurement techniques have limitations.
    • Accurate assessment of body image is crucial in psychological research.

    Purpose of the Study:

    • To introduce a novel, simple video-based procedure for body image measurement.
    • To evaluate the reliability and preliminary validity of this new technique.

    Main Methods:

    • A standard video camera was modified to alter perceived body size.
    • The modified camera produces images appearing 20% thinner to 40% fatter without distortion.
    • Reliability and preliminary validity were assessed.

    Main Results:

    • The modified video camera procedure demonstrated reliability.
