Timeline/Calendar funcionalities

Hi, colleagues,
Can anyone inform it Survey Solutions supports the implementation of a Computerized “Event History Calendar” Questionnaire?
Basically the instrument, also known as “Life History Calendar”, “Timeline” or equivalent has 3 important characteristics:
(a) The instrument includes a graphical display of the time dimension. Usually, the reference
period is divided into smaller time units, such as years, months or days. The size of those
time units mainly depends on the length of the reference period.
(b) The graphical display encompasses one or more thematic axes, representing the domains
concerning which the data is collected.
© The respondent is provided with temporal bounding cues, such as public or personal
landmark events.

Thanks a lot,
Leandro Mahalem de Lima

Could you please show some examples from other software supporting this feature?

Hi, Sergiy,

Thanks a lot for your answer.
I read about this one: https://formr.org/ but haven’t tested it’s capabilities yet.

Belli R.F. proposed a pilot for the Panel Study of Income Dynamics (PSID) but it was not updated (as far as I know, see: [(2000). Computerized Event History Calendar methods: Facilitating autobiographical recall. American Statistical Association, Alexandria] ).

A version of this computerized EHC is used during personal interviews of the LAFANS [see Pebley, A.R., Sastry, N.: The Los Angeles Family and Neighborhood Survey: Field Interviewer Manual: RAND (2004)].

Thanks again for your support,


A recent review about Calendar/Timeline survey methods can be read here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2798968/#CR7

Sure, if you manage to see this calendar on the tablet in ANY data collection package for your survey, please let me know.

I am not sure if it actually exists, that is why I am asking for support. As far as I know, https://formr.org/ would be the most updated solution.

For us, to have it integrated on Survey Solutions would be the best case scenario.

Thanks again.
