The study revealed that the patients had pre-operative traitand state anxiety at middle toward low level, but had high levelin pre-operative information needs. The trait anxiety waspossitively correlated with the state anxiety at moderate level.The trend of the relationship between trait anxiety andpre-operative information needs approached nearly the significantlevel (p=.09), but no relationship between the state anxiety andpre-operative information needs was found. Difference in sex andage was found to have statistically significant different in traitand state anxiety. Female had higher trait and state. However. there were no significantly difference on nursingagency for agency for both self and head nurse evaluationaccording to trainig course, duration of working experience, andworking unit.

However, various limitations pertaining to themeasurement of nursing agency and the selection of the sample werediscussed anxiety than male. Patients whose age between 21-40years had higher trait and state anxiety than those at the age61-80 years. But those who had only elementary education or lowerhad higher trait anxiety than those who had higher education. Andthose who had surgery of the female-reproductive organs also hadsignificantly higher trait anxiety than those who had abodominalsurgery. It was found that tyhose who were differences ineconnmic problems, previous surgical experiences and diagnosis hadno significant difference in both trait and state anxiety.Pre-operative information needs among cancer patients wassignidicant higher than non-cancer patients, but no significantdifferences were found abong the patients who had difference insex, age, educational level, economic problem, previous surgicalexperience, and operative site. The information concerningrehabilitation was needed the highest by the patients.
