Illness Behavior: Prediction by Symptoms, the Grossarth-Maticek and Eysenck Personality Types, Neuroticism, Life Events, Coping, Health Locus of Control, Social Support, and Attribution Style

A study was carried out with 501 persons to analyze the predictive capacity of various psychosocial variables—symptom perception, neuroticism, Personality Types 2 and 4 of Grossarth-Maticek and Eysenck, beliefs about health, social support, or certain coping styles—on two health-related behaviors: the frequency of visits to the doctor and self-medication. The results were analyzed by two structural equation models that revealed that some of the variables have direct effects on the behaviors, whereas other variables, such as attribution style, coping styles, or the impact of the stressors, have indirect effects via the reported symptoms or neuroticism. In addition, self-medication and the frequency of health service visits are independent of each other, which shows that their determinants are different. It is concluded that to address these factors in the two health indicators, it is also necessary to take in account the psychosocial variables considered herein.

Interaction of psychosocial and physical risk factors in the causation of mammary cancer, and its prevention through psychological methods of treatment

Some 8059 healthy women (mean age 58 years) were studied in 1973 with the aim of establishing the presence or absence of a variety of physical and psychological risk factors for mammary cancer. Mortality was established in 1988. factor predictors were highly significant. Physical risk factors were more predictive than psychological ones, but both interacted synergistically to predict mortality. Alone, psychological (stress) factors had little effect, while-physical factors did. However, psychological factors seemed to potentiate the effect of physical factors, particularly in the middle range. The causal relevance of psychological factors was established in a special intervention study using autonomy training as a method of prophylactic therapy and comparing outcome with the effects of no therapy (control).
