Table 4 Suggestions for increasing the uptake of the intervention http://www.wiagesprek.nl

Reach

Low: 9% of all claimants will use the intervention.

Under-representation of ethnic minorities, lower-educated and male claimants.

By adapting the Implementation strategy:

- Start recruitment in an earlier stage, e.g. one month before the disability assessment

- Independent delivery, through other channels than UWV, e.g. patient organizations

- Invitations to use the intervention more directed at not-Dutch born claimants and lower educated claimants, e.g. by using multilingual brochures

- Recruitment not only online, but by a more personal invitation, e.g. by phone

- Increase perceived advantage, e.g. by adapting the content of the invitation brochures, experimenting with different contents, lay outs etc.

Compliance

Low: 33% of claimants that are interested to use the intervention, use the intervention as intended (more than 2 hours).

By adapting the Innovation itself:

- To prevent that attrition leads to missing out relevant information, make a "a la carte" menu, in which claimants can choose what type of information they are interested in

- Delete non-used or barely used components of the intervention, such as the forum, calendar/diary

By adapting the Implementation strategy:

- Start recruitment in an earlier stage, to give claimants that have logged on and started the program, enough time to finish the program
