We give two general criteria under which such results may be deduced from `strong stability' forms of the corresponding (pure) extremal results. These results hold for the \\alpha-spectral radius defined using the \\alpha-norm for any \\alpha>1; the usual spectrum is the case \\alpha=2.\n  Our results imply that any hypergraph Tur\\'{a}n problem which has the stability property and whose extremal construction satisfies some rather mild continuity assumptions admits a corresponding spectral result.
