Hi mates, for a while I’ve been receiving a lot of partial replies for my surveys. Looks like robots or SPAM but I don’t know how to stop it. I tried to set a CAPTCHA element before starting the surveys but without success. I get around 5/10 partial replies (even when partial responses are not allow). Does anybody have any suggestion? However there aren't any problem with completed answers.

Thanks,

We might first have to define what partial replies means to you.
Do you mean partial saved responses or partial responses (which are just not finished surveys). The partial saved responses are saved intentionally via a different button.

What "partial replies not allowed" mean?

Depending on subject, surveylength and incentivation a 50% rate of completeness is fine.

Thanks Jelo. I effectively mean "partial responses (which are just not finished surveys)" without any information load: empty partial responses. With "partial replies not allowed" i refeer that the option "Participant may save and resume later?" is disable.

It is very common that people start a survey because they are curious, but then use interest. In many cases, especially they are not receiving any incentives the drop out rate can be quite high (depends very much on the topic, the length of the survey, the question types used, etc.).

Over the years experience has shown us that the following question types cause higher dropout rates:
- Long array / matrix questions
- Open ended questions
