The scalar meson f{sub 0}(1370) - indicated in particular in the low energy pp-bar{yields}3 body reactions - is a crucial element in certain schemes of the scalar meson spectroscopy including glueballs. The most definitive results can be obtained from elastic and inelastic {pi}{pi} phase shift analyses using the constraints from unitarity where the discrete ambiguities can be identified and resolved. We reconsider the phase shift analyses for {pi}{sup +{pi}-{yields}{pi}+{pi}-}, {pi}{sup 0{pi}0}, KK-bar, {eta}{eta}. While a clear resonance signal for f{sub 0}(1500) in the resp. Argand diagrams is seen in all channels above a large 'background' from f{sub 0}(600) there is no clear signal of a second resonance 'f{sub 0}(1370)' in this mass range in any reaction, at the level of {approx}10% branching ratio into {pi}{pi}.
