Salivary secretion was measured in 54 psychiatric patients comprising four diagnostic groups: schizophrenia, mania, depression and anxiety state. Detailed psychometric assessment was carried out at the time of measurement. Although salivary flow failed to show an association with either diagnostic category or mental state at the time of examination, it was positively correlated with a subjective rating of appetite. The implications of these findings are discussed.
