The Privacy Consciousness Scale (PCS) was developed to measure privacy consciousness for the self and others, and its reliability and construct validity were examined. Undergraduates completed the PCS in two studies. Factor analysis of their responses on the scale revealed three dimensions: Privacy Consciousness for the Self/Behaviors to Maintain the Privacy of the Self (7 items); Privacy Consciousness for Others (4 items); and Behaviors to Maintain the Privacy of Others (4 items). These studies also examined the relationships of the PCS to information privacy, privacy preferences, empathic concern, and behavioral standards for public space. The results confirm that the PCS has reliability and construct validity.
