We discuss a possible interpretation of the f{sub 0}(980) and a{sub 0}(980) mesons as hadronic molecules--a bound state of K and K-bar mesons. Using a phenomenological Lagrangian approach we calculate the strong f{sub 0}(980){yields}{pi}{pi} and a{sub 0}(980){yields}{pi}{eta} as well as the electromagnetic f{sub 0}(980){yields}{gamma}{gamma} and a{sub 0}(980){yields}{gamma}{gamma} decays. The covariant and gauge invariant model, which also allows for finite size effects of the hadronic molecule, delivers results in good agreement with available data and results of other theoretical approaches.
