By means of the questionnaires to check subjective symptoms related with occupational cervicobrachial disorder (OCD), which were made by the committee of OCD in Japan Association of Industrial Health in 1972, we obtained the data of 59 female key-operators working for a certain industry. The items of the questionnaires are composed of 5 parts, namely, items of symptoms about extremities, trunk and neck, those of visual, auditory and general symptoms, those of complaints about upper extremities, those of complaints about the autonomic nervous system and coordination, and those of complaints about mental functioning. We calculated the scores of each of 5 parts and gave names to these scores as variables, PART, NONPART, UPPERLIMB, AUTONOMIC and MENTAL, respectively. And from other questionnaires, we selected the following data of the subjects and quantified them as variables: age (AGE), status of marriage (MARRIAGE), number of subject's children (CHILDREN), working period as a key-operator (WPERIOD), grade of neurotic symptoms assessed by Cornell Medical Index (CMI) and score of household-centered time-budgeting pattern (calculated from the table of time-budgetings of subject's daily life through principal factor analysis method) (HOUSEHOLD). Uing the variables mentioned above, we tried Path Analysis applying multiple regression analysis to presume inter-variable causalities, and to conjecture the factors which may take part in the development of subjective symptoms. And, we carried out further multiple regression analyses to make it clear which items of the questionnaires for subjective symptoms are associated with variables: AGE, MARRIAGE, CHILDREN, WPERIOD, CMI and HOUSEHOLD. As a result, we found a positive association of PART with WPERIOD, NONPART with CMI, UPPERLIMB with WPERIOD, HOUSEHOLD and MARRIAGE, and a negative association of NONPART with HOUSEHOLD. From these results, it can be said that household may have an aggravating effect on subjective symptoms of upper and lower extremities, on the other hand, household-centered life style alleviates general symptoms (NONPART), and that persistant load of key-operating work represented by WPERIOD, increases symptoms of extremities, and so on.
