Hello,

I've been playing with the assessment function trying to find a way to do what I want, without much success.

Essentially, is there a way to compute subscales scores and total score for normal coded and reverse coded items (to be used for a personality questionnaire).


Example:

40 items in an array, rated on a 6-point answer scale (strongly disagree (1); disagree (2); slightly disagree (3); slightly agree (4); agree (5); strongly agree (6).

Half of those items (all odd number items (e.g. item #1, item #3, item #5, etc.) are reverse coded (so strongly disagree is worth (6), disagree is worth (5), etc.)

Four subscales are computed (items 1 to 10, 11 to 20, 21 to 30, and 31 to 40), alongside a total score for all items (1 to 40). The subscales scores and the total score is the sum of all the points based on the 6-point answer scale (taking into account the reverse coded items).

How can I achieve all of that? At the moment, the best I managed was to have a total score for a test with no reverse coded items. The end goal will be to present test respondents personalized PDF with their score and personalized text corresponding to their score for each subscales and total score. Thank you

Hi,
you should use Expression Manager.
E.g. your first subscale:

{sum((7-Q1_SQ001.NAOK),Q1_SQ002.NAOK,(7-Q1_SQ003.NAOK),Q1_SQ004.NAOK),(7-Q1_SQ005.NAOK),Q1_SQ006.NAOK,(7-Q1_SQ007.NAOK),Q1_SQ008.NAOK),(7-Q1_SQ009.NAOK),Q1_SQ0010.NAOK)}
