Hello fellow forum-users!

I am curious if it is possible to redirect participants with false answers in an attention check item (like "Please tick "extremely important" here.") to a separate ending page. The attention check item is integrated in a matrix question design with various other items. I thought of using a quota and set the limit to zero (so nobody should be able to proceed with the quetsionnaire if he answers anything else then "extremely important") but this isn´t applicable in matrix questions. Are there any other options, to redirect inattentive participants to stop them from proceeding with the questionnaire?

Help me Lime-Survey users, you are my only hope...

Thank you for all ideas and answers!

Buzzword: Quota (as you supposed already)
create an equation (eqQ0) that returns a special value (0) if the respondent selects something else.
Something like:
{if(Q0_SQ001!=5,0,1)}
Set a quota on this equation with limit "0".
 
Read the manual for more.

Thank you for the helpful support! So I created an equation to return the value 0 for my attention check item in the matrix on the same page, now I hide the equation on the page and set the quota to zero for participants who have a 0 in the equation. Could you shortly explain how the function works? Like if someone ticks the 5 the equation returns the 1 and otherwise if some ticks something different than 5 it returns the 0, right?

Yes?!

Something like (not tested and needs to be adapted to your question and subquestion codes, of course):

[code]{if(Q1_SQ01==5; 1; 0)}
