Self-consciousness has been an important trait in personality research. It seems logical to investigate whether health consciousness, involving a similar self-focusing, might operate in a parallel manner. To this end, I developed the Health Consciousness Scale (HCS), primarily by modifying items of the Self-Consciousness Scale, and also tested it for reliability and validity. My study found the HCS to contain four first-order factors: (1) Health Self-Consciousness, (2) Health Alertness, (3) Health Self-Monitoring, and (4) Health Involvement. I found these four first-order factors, along with the overall HCS second-order factor, to relate to a number of self-reported, health-associated behavioral variables. The study also included comparisons with the Health Locus-of-Control Scale and other measures.
