This is a pilot study on developing a method of a one-month survey on tiredness of a single worker. The aim of such a survey was assumed to give the worker an opportunity to consider everyday activities done in his/her present working, life, in order to improve it in the near future. The purpose of the present study was to examine whether the procedures used in the survey could be effective for achieving the aim.
A female nurse who worked an irregular three shift system was served as the subject of the survey. She was 42 years old with two children aged 8 and 4 years. A survey on tiredness was carried out three times during about 30 days, using seven kinds of inventories on tiredness (on-duty and after-duty of three duty days, and days off), each of which had 12-18 tiredness items. In the survey, she was asked to fill in the inventories every day during a period of 7-10 days and then she was interviewed by the surveyor. In the interviews, she was asked to explain reasons about a large or small number of tiredness items which were responded ‘yes’ on the inventories on these days, and had a discussion about the results with the surveyor.
This study showed that the procedures used in the survey were valid for attaining the aim of the survey:
1. The subject filled in a very small number of ‘yes’ responses to the tiredness items on days off when she had activities intended to do in expectation, e.g. to visit an amusement park under promise with her children. On the other hand, when days off were the next days of her evening or night duty day, she noticed that the number of the ‘yes’ responses became large because of resting or sleeping at home. It was found that the subject could understand clearly that her tiredness on a day off was closely related to whether she spent the time of the day actively or passively.
2. Repetitive discussion about the results of the survey with the surveyor gave the subject an opportunity to think of the importance of having her private time unaccompanied by her children for her better life. After the second survey, she offered to have such free time periods with her three intimate mother nurses working in different duty sequences in the same hospital. The four nurses went on an overnight trip after they worked a morning duty on the following day off. They had their pleasant time spent without their children after a long period of one year and a half. Her active action was carried out successfully.
