Abstract: In this paper the "Shibata Nakao and Nakamura" (SNN) gauge for scalar gravitational waves (SGWs)is reanalyzed, showing that in [1] there was an error in the geodesic equations of motion. This error conditioned also the analysis of [2] and [3] where wrong equation of motion taken from [1] were used. In the analysis of the response of interferometers the computation is first made in the low frequencies approximation, then the analysis is applied to all SGWs using a generalization to the SNN gauge of the analysis of [4] where the computation was made in the TT gauge for tensorial waves. At the end of this paper the correct detector pattern of interferometers in the SNN gauge is also computed with a further generalization of the analysis of [4] to the angular dependence of the propagating SGW.
