The purpose of this study was to evaluate the validity of the Stress and Stress-Coping Questionnaire (SSCQ) for female nursing groups. Subjects were 300 female nurses employed at hospitals. Mean age was 32.9±8.9 yr and mean number of years of work experience was 11.9±8.0 yr. Data for the study were collected via the self-completed SSCQ, which all subjects completed. In order to asses the validity of the SSCQ, subjects were also asked to complete a 60-question General Health Questionnaire (GHQ) that assessed mental well being. Based on the results of factor analysis, the original version of the SSCQ, comprising 153 questions in 10 subscales, was revised to the nurse-specific SSCQ-N, comprising 123 questions and 15 subscales. Cronbach's alpha coefficient for subscales varied from 0.70 to 0.83, showing a significant correlation with the point score of the GHQ, for demonstrating criterion-related validity in the SSCQ. These results verify the usefulness for female nursing groups of the SSCQ for assessing mental well being and suggesting ways to manage stress in nurses. (San Ei Shi 2005; 47: 1-10)

"The Checklist for Evaluation of Mental Health Activities at the Workplace" was developed for workplace staff evaluating mental health activities in their own workplace. The validity and reliability of the checklist were examined and criteria for evaluation were developed for workplace/organization/companies with 50 or more employees in Japan. The checklist initially included 33 items covering seven major domains of occupational mental health, with a four-point response option, based on the Japanese Guideline for Worker Mental Health in the Workplace and a relevant literature review. A questionnaire was send to 60 members of the Occupational Mental Health Committee (OMHC) of the Japan Society for Occupational Health to ask their opinions on the checklist and on the minimum requirement for each item on the checklist; 30 (50%) responded. A random sample of 1,335 workplaces from a contractor list of workplaces for worker compensation insurance and a questionnaire was send to the personnel department to fill in the checklist; 412 (31.5%) responded and data from 335 of them with 50 or more employees were analyzed. Some OMHC members felt that one of the items (concerning the Total Health Promotion program) should be dropped; thus the checklist was revised to include 32 items, still covering the seven domains. Based on the workplace survey data, most domain scales showed internal consistency reliability at an acceptable level; explanatory factor analysis yielded a four-factor structure that was well concordant with the hypnotized seven-domain structure. Three levels of adequacy of mental health activities were set for each domain scale: "red" (inadequate), "yellow" (minimal), and "green" (adequate). One third of occupational health professionals from 49 workplaces rated the evaluation result based on the checklist as concordant with their view; 95% of them said the checklist would be useful in promoting occupational mental health activities. The study indicated that the checklist had reliability (based on internal consistency reliability) and content- and construct-validity (based on expert opinions, a factor-structure concordant with empirical data, and evaluation by workplace staff). The checklist seems useful in promoting occupational mental health activities. (San Ei Shi 2005; 47: 11-32)

In 1992, Brugada et al. reported a characteristic electrocardiogram (ECG) pattern and ST-segment elevation in leads V1 to V3 associated with sudden death in patients without demonstrable structural heart disease. That disease is now called Brugada Syndrome. The diagnostic criteria for the Brugada Syndrome have still not been decided on, and the prevalence of Brugada type ECG (B-ECG) varies widely in Japan. Therefore, we should consider B-ECG according to the consensus statement from the European Society of Cardiology and we proposed its management in health examinations. There were 35 B-ECG cases (0.9%), all male out of 3,875 Postal Service Trainees. There were 5 cases of Type I(Coved) (0.13%), 21 cases of Type II(0.54%), and 9 cases of Type III(0.23%), Only one case (0.026%) of Brugada Syndrome was found, and eventually, he received an Implantable Cardioverter Defibrillator (ICD). Type I(Coved) may be a more important electrocardiographic factor having a stronger causal relation to Ventricular Arrhythmia. Therefore, in management of health examinations, Type I patients with syncope or a family history of sudden cardiac death should visit a cardiologist for ICD-implantation, and even without any cardiac symptoms (syncope and a family history of sudden death), they are advised to visit a cardiologist for a program electrical stimulation (PES). Type II and III patients with any cardiac symptoms are advised to visit a cardiologist for PES or a drug challenge. (San Ei Shi 2005; 47: 33-39)
