The present invention provides a signal quality detection method for an ear-chip physiological measurement device. The signal quality detection method includes receiving a sensing signal from the ear-clip physiological measurement device; filtering the sensing signal to generate a pre-processed signal; calculating a physiological index according to the pre-processed signal; and calculating a similarity of a red light alternating current (AC) component and an infrared light AC component of the pre-processed signal and a plurality of correlation coefficients of the red light AC component, and generating a reliability index of the physiological index accordingly. The reliability index indicates one of a plurality of signal qualities.
