Measures the degree to which a person believes that their responses to a survey or study will remain private and confidential rather than being shared with or made public to others in the research setting. The scale captures the perceived anonymity and non-disclosure of participant responses within a specific research context.
Full scale items shown. Always cite the original source when using this scale in research.
Developed by Green & Peloza (2014) and used in Studies 1 to 3. Conceptually based on White & Peloza's (2009) work on public versus private response contexts, where beliefs about public or private conditions were manipulated rather than measured. Here both manipulation and measurement were employed. Alphas were .94 (Study 1), .97 (Study 2), and .97 (Study 3). Validity not examined directly; predictive validity is inferred from the scale's successful tracking of public/private manipulations across studies. Items 1 and 2 are reverse-coded (r). Items 1 and 4 are phrased specifically for experimental contexts (reference to 'everyone else here today' and 'others in the room') and may require rephrasing for use in non-laboratory settings; each such rephrasing warrants re-checking the scale's psychometric quality before use in theory testing. Response anchors were not stated but are assumed to be standard Likert-type (strongly disagree / strongly agree).
