Assumptions Underlying the Revised Response Shift Model

A. Epistemic assumptions
A1. The target construct and “other variables” (catalyst, antecedents, mechanisms, measure) are conceptually distinct
B. Methodological assumptions
B1. The measure pertains to an evaluation-based self-report  B2. The measure results from the responses to the items as well as from the algebraic transformation applied to derive an estimate of it. As this algebraic transformation is the same at each time, it cannot cause different results over time
B3. The items of the measure are free from poor or ambiguous wording
B4. The measure is reliable and valid
C. Practical assumptions
C1. The catalyst is sufficiently impactful to influence the respondents’ perspective on the measure, either directly or via its influence on mechanisms
C2. Some antecedents may influence the respondents’ perspective on the measure at each time point  C3. Some mechanisms may influence the respondents’ perspective on the measure
C4. Response shift occurs in change processes and requires therefore at least two time points
C5. The target construct can be anything that can be measured with evaluation-based self-report
