Construct validity and responsiveness of the Dutch Keele Assessment of Participation, based on prior hypotheses about expected correlations; Spearman correlation coefficients between (change) scores of the KAP domains and IPA domains, RAND-36 domains (RP, RE and PF) and (instrumental) activities of daily living index
| KAPd1 | KAPd2 | KAPd1 change | |||
|---|---|---|---|---|---|

| S | IPA work and education | 0.21 | 0.35 | – | |
| S | RAND-36 role-physical | 0.50 | 0.36 | RAND-36 role-physical change | 0.12 |
| S | RAND-36 role-emotional | 0.39 | 0.32 | RAND-36 role-emotional change | 0.12 |
| D | RAND-36 physical functioning | 0.50 | 0.39 | RAND-36 physical functioning change | 0.13 |
| D | Activities of daily living (0–6) | 0.36 | 0.25 | Activities of daily living (0–6) change | 0.12 |

Hypotheses: (1) similar constructs correlate >0.50; confirmation=bold, (2) dissimilar constructs correlate with 0.30–0.50; confirmation=bold (3) difference between KAP domains 0.10.
Bold indicates confirmation of hypotheses 1 and 2. Underlined indicates confirmation of hypotheses 3.
D, dissimilar constructs of participation; IPA, Impact on Participation and Autonomy; KAP, Keele Assessment of Participation; S, similar constructs of participation.
