Conceptual Model of the Psychosocial Effects of Beryllium Sensitization and Chronic Beryllium Disease

Abstract

The objective of this research was to develop a theoretical model that describes the psychosocial effects of beryllium sensitization (BeS) and chronic beryllium disease (CBD). The medical, nursing, health education, and psychological literature was reviewed to identify theories that might support the development of a psychosocial model of BeS and CBD. A proposed model was synthesized based upon elements from multiple academic disciplines. The conceptual model is based on three prominent psychological theories: 1) health, stress, and coping, 2) uncertainty and illness, and 3) psychosocial adjustment to illness. The model hypothesizes that workers who are diagnosed with BeS or CBD experience a great deal of uncertainty that has a detrimental effect on their health quality of life. The focal relationship in this model is between the independent variable uncertainty and the dependent variable health quality of life. It is further hypothesized that the relationship between these two variables is affected by an intermediate variable, the ability to make psychosocial adjustments to disease. Creating this model is a step toward filling a void in our understanding of the natural history of CBD. Once validated it will establish a foundation for future research, interventions and program evaluations and may lead to changes in the psychological, social, financial, and disease management support provided to this population.
