Measuring intrinsic motivation: all scientific details
01 – the scientific foundation
Holland RIASEC
Holland’s model describes occupational interests across six orientations. The central idea is not that one level is better than another. What matters is the fit between a person’s interest profile and the activities and environment of a specific role. That is why Traitwise does not read intrinsic motivation as a general motivation score, but as a match with the role profile.

| Task type | Occupational interests |
| Response format | Likert scale (1–5) |

| Scoring | Congruence coefficientMatch between person profile and role profile. |

| Reference | Job-specific interest profileRIASEC values of the occupation from O*NET (US Department of Labor, more than 900 actively maintained occupation profiles); European occupations are mapped via ESCO where needed. |
| Criterion validity | r = .24Occupational interests, Sackett et al. (2022). |
| Reliability | Cronbach’s alpha = 0.81 |
| Model fit | RSQ = 0.95Structural validity: the two-dimensional RIASEC arrangement reproduces 95 percent of the observed distances between the six interest scales. A model statistic, not a candidate score. |
| Objectivity | Standardised administration, automatic scoring |
