Alejandra Gonzalez-Beltran Orlaith Burke Philippe Rocca-Serra STATO statistical sample study group population a cohort is a study group population where the members are human beings which meet inclusion criteria and undergo a longitudinal design cohort Pearson's correlation coefficient Process of transforming (translating) the generated instrument in the target langauge (i.e., a draft of the translated instrument), back into the language of the used instrument Backward Translation Process by which someone who is blind to the original (untranslated) text resolves discrepancies between multiple forward translations Blind Review Process that includes an independent translator or an expert panel to identify and resolve any discrepancies between multiple forward translations, reconciling them into a single instrument. Requires forward translation to have occurred. Double-Translation and Reconciliation Process by which an individual or group of individuals review changes from the used instrument to the generated instrument and provide feedback to others associated with the activity Expert Review Process of transforming (translating) the source language (i.e., the language of the used instrument) into a target language (i.e., the language in which generated instrument is to be administered) Forward Translation 2 instrument collection A set of measurement instruments that have been derived from each other, are published by the same organization, or have some other reason for close association Process that includes distributing the generated instrument to the intended target population and collecting feedback Interview 1 item stem concept the experience or construct that the question or statement used to prompt an individual intends to capture 1 composite scale a questionnaire scale with one or more subsets of questions comprising another questionnaire scale psychological construct construct a hypothetical or theoretical entity that can not be directly observed experience an informant's observation or encounter in a situation or event psychometric questionnaire a questionnaire used to measure an individual's mental capabilities, behaviors, or psychological traits 1 1 questionnaire scale a set of questions, often within a questionnaire, for obtaining information and/or a numeric result about one particular condition a sufficient set of co-occuring symptoms believed to represent an underlying phenomenon with dimensional properties
