  We investigated the star formation efficiency for all the dust emitting
sources in Stephan's Quintet (SQ). We inferred star formation rates using
Spitzer MIR/FIR and GALEX FUV data and combined them with gas column density
measurements by various authors, in order to position each source in a
Kennicutt-Schmidt diagram. Our results show that the bright IGM star formation
regions in SQ present star formation efficiencies consistent with those
observed within local galaxies. On the other hand, star formation in the
intergalactic shock region seems to be rather inhibited.
