Extracting measures from classical ethnographies has always necessitated proxy indicators in cross-societal research. Methods are given for calculating indexes of validity and reliability for both a low inference measure x and high inference proxy measure y of the same conceptual variable Z. Where two different ethnographic descriptions A and B exist for each society in a sample, low inference measures xA and xB are used to assess validity and reliability from the classical “true score” measurement model x = t + eX, t is the true score, eX is error, ?[EX] = 0. Tests establish whether the model fits data. Reliability is defined to be (1 – Var[EX]/Var[X]). Validity is Var[T]/Var[X]. The validity and reliability of high inference measure y are increased by fitting a curve x = f(y) + ef(y), ?[Ef(y)] = 0, to data. Standard cross-cultural sample examples are given. Solutions for cross-societal research may be considered for cross-cultural research.
