[The health status of stomatologists based on the Cornell Medical Index questionnaire].

The Cornell Medical Index--CMI was used in a group of 674 stomatologists from the North Moravian region to obtain information on their health status. The control group was formed by 126 health community doctors and factory medical officers from the Olomouc, Sumperk and Prerov districts. The results confirm that stomatologists, a risk group, suffer significantly more from somatic and mental problems, as compared with the control group.

[Factor analysis of Cornell Medical Index and Medical Data Index (author's transl)].

Structures of Cornell Medical Index and Medical Data Index were examined by factor analysis. Both of the translated questionnaires were self-administered by six hundred male employees. Questions of low response rate less than 5 and 6% were excluded, and 117 and 70 questions were analysed finally by the method of varimax rotation for CMI and MDI respectively. Ten factors were extracted. Cummulated contribution ratio of them amounted to 72.0 and 84.1% for CMI and MDI respectively. The first two factors were common for the both questionaires and had pronounced contribution ratio amounting to 36.7 and 29.3% for CMI and MDI respectively. The first factors was composed of questions related to autonomic inbalance, gastrointesinal symptom and fatigue, so it was named a tendency of many physical complaints. This factor was considered to be characteristic and representative one in such general health questionnaires, which was closely related to response set of the respondent. The second factor of the questionnaires was named mental instability. The two major factors would correspond to the first and the second component of the Subjective Fatigue Complaint Test (1970) by Japan Association of Industrial Health. Not also CMI but MDI were found to have a poor scalability except for the two major factors.

Cornell Medical Index responses and mortality in a Polynesian population.

The Cornell Medical Index (CMI) is a health questionnaire consisting of a somatic division, divided into 12 sections organized by organ systems, and a psychosocial division. It has been suggested that the CMI taps a dimension of the perception of illness before clinical measurements detect disease. However, this has not been confirmed in nonwestern populations. Our purpose was to determine if the CMI predicted 6-year mortality in a Polynesian population. In 1975, 461 American Samoan men responded to the CMI. Thirty-one died between 1976 and 1981, 13 of cardiovascular disease (CVD). A logistic model was used to predict both total and CVD mortality during the follow-up period. Positive responses to the total, somatic, and psychosocial divisions of the CMI did not significantly improve prediction of mortality compared to models using only age. An analysis using section scores showed that several somatic sections were associated with CVD mortality, but none were associated with total mortality. This study suggests that the CMI is not a strong predictor of mortality and, by extension, of existing health status in American Samoa. Even if the CMI does measure the perception of illness, one cannot assume a priori that it is valid in any given anthropological population. Rather, the instrument must be pretested in each particular cultural setting.

Psychoneurological symptoms during interferon therapy in patients with chronic hepatitis: prospective study on predictive use of Cornell Medical Index and electroencephalogram.

BACKGROUND/AIMS: We assessed the usefulness of the Cornell Medical Index (CMI) and electroencephalogram (EEG) in the prediction and early detection of psychoneurological symptoms associated with interferon (IFN) therapy for chronic viral hepatitis. METHODS: Forty-eight consecutive patients received IFN for chronic viral hepatitis for 8-24 weeks. CMI was measured before IFN therapy. Serial EEGs were recorded before IFN therapy, 2, 4 weeks, and thereafter every 4 weeks in the therapy. RESULTS: Psychoneurological symptoms including insomnia, depression, and restlessness were seen in 11 (23%) of 48 patients. Five (13%) of 40 patients with CMI I and II and six (75%) of eight with CMI III developed psychoneurological symptoms (P<0.001). Sensitivity, specificity, and predictive accuracy of CMI III were 55%, 95%, and 75%, respectively. Abnormal EEG such as slow basic rhythm, appeared in 13 patients (27%) during IFN therapy. Psychoneurological symptoms were seen in six (46%) of the 13 patients with abnormal EEG, and in five (14%) of 35 in whom EEG remained normal (P<0.05). CONCLUSIONS: CMI is useful for the prediction of IFN-induced psychoneurological symptoms in patients with chronic viral hepatitis. Serial EEGs contribute to the screening and auxiliarily assessing the adverse effects of IFN on the central nervous system.

Two shortened versions of the Cornell Medical Index--a new test of their validity.

Two shortened versions of the Cornell Medical Index (CMI) were tested for concurrent validity using two reference groups. Sensitivity, specificity and relative liability were computed and found to be of relatively low value. The usefulness of the questionnaires for screening the emotionally disturbed was found to be affected by respondents' sociodemographic characteristics such as age and sex and, in particular, educational level and ethnicity.

Psychiatric symptom dimensions in the Cornell Medical Index among normal adult males.

Factor analysis of items from the psychiatric portion of the Cornell Medical Index (CMI) was performed to determine the empirical symptom dimensions in a sample of 1682 normal adult males. Six factors were extracted and interpreted as Irritability, Inability to Cope, Depression, Timidity, Normal Anxiety, and Clinical Anxiety. The factors showed some correspondence to the clinical groupings in the CMI and to factors discovered in other studies. Whiel all showed small positive correlations with a measure of Neuroticism, the consistency of these results argues against the hypothesis that the CMI M-R sections measure only a urinary factor of neurotic complaining. Some modifications in the CMI are recommended that could emhance its utility as a diagnostic or personality instrument.

Symptoms reported on the Cornell Medical Index in relationship to hypertension and age.

This study compared young and old hypertensive and normotensive subjects with respect to the number of symptoms reported on the Cornell Medical Index (CMI). The hypertensive subjects had more physical and psychological complaints than did the normotensive subjects. Differences in symptoms reported between the blood pressure groups were not concentrated in one specific category (e.g., cardiovascular) but were distributed over several categories. Age did not influence the number of symptoms reported for either blood pressure group. The results were discussed in the context of the lack of specificity of symptoms reported by hypertensive subjects, and to what extent reported symptoms on the CMI are influenced by knowledge of one's blood pressure status.

Concordance of Cornell medical index self-reports to structured clinical assessment for the identification of physical health status.

Self-reported questionnaires are frequently used to assess health status in epidemiological studies. The Cornell medical index is one such tool used to determine the presence of physical and psychiatric illness but its accuracy and value have been questioned. In this study we have assessed the ability of the CMI to predict health status in two separate patient populations (n = 101, 88) by comparison to a structured medical assessment based on the SENIEUR protocol by two physicians. There was good agreement between medication use reported on the CMI and on medical assessment (k = 0.79; CI: 0.70-0.88). Accuracy of prediction of the CMI for specific medical conditions was good 89-99%. A threshold score from the CMI was not predictive of health as determined by the SENIEUR protocol. In our older populations, we conclude that the CMI accurately predicted health status. The determination of normal health by a threshold score was poorly predictive of heath status. Self-reported medication use was the best predictor of health status.

Comparison of the General Health Questionnaire and the Cornell Medical Index Health Questionnaire.

This study compares the 30-item version of the General Health Questionnaire (GHQ) and the psychiatric section of the Cornell Medical Index Health Questionnaire (CMI-MR) using normative data from a sample of the general population and data from general practice patients where clinical assessment by a psychiatrist is used as a criterion of psychiatric caseness. In this study the CMI-MR has a slightly better overall performance as a screening test. It appears that the CMI-MR errs in the direction of false negatives when the symptoms are recent and related to situational stress, but the GHQ has a tendency to miss cases with symptoms of long standing.

[Health check by CMI (Cornell Medical Index) on radiation workers in a nuclear energy plant].

In the nuclear energy industry, plants are located far from urban areas and the working environments are generally separate from each other for radiation protection purposes. A health check on radiation workers in the nuclear energy industry was carried out using the Cornell Medical Index questionnaire. As a control study, radiation and non-radiation workers in the other working fields were investigated in the same manner. The results showed that the health status of radiation workers in the nuclear energy industry is similar to that of the workers in other working fields.

Cornell Medical Index: a comparative study on health problems among Thai and Japanese nursing students.

Cross cultural differences in subjective physical and psychological health problems reported on the Cornell Medical Index (CMI) Thai and Japanese versions were conducted among Thai and Japanese female first year class nursing students from two nursing colleges. All of the Thai (114) and 96.2% (102) of the Japanese subjects self-administered the CMI. The internal consistency reliability of each CMI was acceptable. Mean ages of the Thai and the Japanese subjects were 19.3 (SD = 0.8) and 18.4 (SD = 0.5) years respectively, which was not significantly different. Mean CMI for the physical, psychological and overall health complaints of the Thai subjects were 29.8 (SD = 13.5), 14.5 (SD = 8.0), and 41.3 (SD = 19.3) respectively, and those for the Japanese subjects were 15.7 (SD = 11.8), 7.3 (SD = 6.1), and 23.1 (SD = 15.9) respectively, which were significantly different. Findings indicate that the Thai nursing students have more health problems than the Japanese subjects. These mostly concerned respiratory, cardiovascular, digestive, musculoskeletal, nervous, genitourinary systems, fatigability, frequency of illnesses, miscellaneous diseases, mood and feeling patterns, sensitivity, anger and tension. The only one section that the Japanese reported significantly higher health problems than the Thai subjects concerned daily living habits pertaining to questions concerning such matters as drinking, smoking, exercise, sleeping and rest. Percentages of emotional disturbances or neurotic tendencies of the subjects using the conventional CMI score and the Fukamachi criteria are discussed.
