Type of validity | Research questions |
---|---|
Structural validity | RQ1: Is the assumed internal theoretical structure of motivation (i.e., the SDT continuum of motivation; Fig. 1) represented in the data as it was intended during scale development? a. Do respondents distinguish the five dimensions of motivation? b. Are adjacent dimensions more closely related than non-adjacent dimensions? |
Generalizability | RQ2: Do psychometric properties and interpretations generalize across health worker subgroups (measurement invariance)? |
Convergent and discriminant validity | RQ3: To what extent do relationships between the motivation measure and measures of other related constructs correspond to what is theoretically expected and has been found in previous research with other, established measures? |
