I am looking for a questionnaire testing level of conscientiousness (Big five trait) in a dutch adult population. Because I only need to know the level of conscientiousness and because there are time constraints, I prefer a questionnaire that only addresses this factor. Do you have any suggestions? (In English or Dutch)
Is it possible to just ask only those questions related to conscientiousness from a larger questionnaire?
you may find this article of interest as it lists a number of contientiousness scales

personally, I would use measures that are validated so you can see whether the answers you get from your survey match up with existing measures. You could ask a random half of the sample all big 5 questions and a random half just the contientiousness questions to safe some questionnaire time. But you are probably better off picking a measure specifically for contientiousness.
Hi Kelly,
Nice to see someone else from Maastricht University here.
There are plenty of tests that measure the Big Five and have a good reliability and validity. One of those is the NEO-PI-R, which has been translated to Dutch as well. http://www.unifr.ch/ztd/HTS/inftest/WEB-Informationssystem/nl/4nl001/44c91c3890384282b71f445e4a48f0f5/hb.htm
That link has some info (in Dutch) on the test and on its validity and reliability. The entire test contains 240 items and on average takes about 35 minutes to complete. If you're just going to use conscientiousness, you'd have 48 items which shouldn't take longer than 10 minutes. I'm sure no matter which test you choose, it won't take much longer than this.
As you can see, every 'Big' trait is subdidived into 6 mini questionnaires (facets), each containing 8 items. The reliability - Cronbach's alpha - for the five big domains lies between .82 and .94 for the Dutch version (and is obviously lower for the individual 8-item facets). The domain validity is also good. See wik link below.
Good luck!

Lew Goldberg (one of the main proponents of the "Big 5") has a pool of free items here:
http://ipip.ori.org/new2413Items.htm
About 750 of them (most of the items with "H" identifiers above) started life in Dutch:

Goldberg has also provided widely-used marker scales for the Big 5:
http://ipip.ori.org/New_IPIP-50-item-scale.htm
The (items marked 3+ and 3- are conscientiousness items). The IPIP items are intentionally simple to facilitate translation. Shortened versions of this scale have been published, I think the shortest had just a couple items on it.
The main advantage of the IPIP is that you can freely use these items. In comparison, you are extremely unlikely to get permission to use items from an instrument like the NEO and using them without permission is illegal in almost all countries.
Another advantage of the IPIP marker scales over, say, the NEO, is that the IPIP markers were produce by Lew Goldberg. The NEO was a three-factor instrument retro-fitted to a five factor model (that's why it's the NEO instead of the NEOAC), but you could legitimately call Goldberg the "father" of the Big Five (although Jack Digman, Goldberg's advisor Norman, and many others were involved). I guess my point is that the NEO encapsulates a five factor model, whereas Goldberg's marker scales measure the big five model.
Finally, your second question asked about administering only the conscientiousness items. Goldberg (1992) administered a predecessor adjective checklist in two formats: with all items grouped together by dimension and with all items mixed together. He didn't find big differences. I think you could argue that justifies using the conscientiousness items by themselves.
Goldberg, L. R. (1992). The development of markers for the Big-Five factor structure. Psychological Assessment, 4, 26-42.
I can recommend NEO PI-R, domain C is intended to measure conscientiousness, with 6 facets in it. The reliability of measures is quite good. You can find a lot of articles about that personality dimension, specially about its relations with some other personality traits.
Where can I get short-form of the NEO by Costa and McCrae? If anyone has it can you please share it with me?
Hi, Costa and McCrae SELL their measure for money. Support open and transparent science - here's the IPIP equivalent:

If I only want to measure conscientiousness, is there a Free measure out there with good reliability?
