A list of common triggers was provided in the questionnaire and included the following items: exposure to sun, emotional stress or anxiety, noise, exams, reading hours, eating habits, fasting, menstruation, irregular sleep, physical activity, and smoking.
On the old items, exposure to speech alone (in the No-subtitles condition) yielded better performance than in the Control condition (βcontrol = −0.44, p<0.01, βs indicate differences from the No-subtitles condition).
The assets were merged and dichotomised into having at least one of the items (reference category) versus having none of the items (exposure category).

For highly comparable questionnaire items, exposure-outcome relationship patterns were almost identical between the studies and ORs for eight of the ten relationships examined did not differ significantly.
Besides the large item bank, item exposure mechanism is also essential to a testing system.
Moreover, the researchers apply a novel approach, particle swarm optimization (PSO) to alleviate the computational complexity and resolve the problem of item exposure.
As a result, these large banks of items must first be developed and continually restored in order to reduce item exposure and keep test security while allowing for continuous administration of the test.
Since MSCAT makes use of interchangeable modules that can be shuffled into various forms, it may be easier to manage lower item exposure for smaller banks of test questions.
The time the study will last cannot be determined at this stage since in every administration as is obvious in all CAT, the number of examinees who write any one item is limited because item exposure rates should often be kept to a minimum.
MSCAT is a sophisticated approach for delivering survey tests, and other measurements which is based on complex computer algorithms that through also controlling for practical issues, such as item exposure, test length, and content distribution, adapt the test to every examinee.
However, our use of single item exposure variables did reflect systematic variation across the study cohort and yielded meaningful results.
