Due to recent contradictory results, the period-luminosity-color relation of δ Scuti stars has been examined by a maximum likelihood method. δ Scuti stars are found to definitely obey a period-luminosity-color relation. The derived coefficients are very similar to those derived for RR Lyrae variables. Care has to be taken to allow for the large mass differences between the population I variables, such as δ Scuti stars, and population II ultrashort period pulsators.
