Reliabilities, Means and Standard Deviations for LPC Scales: Instrument Refinement

Abstract

Mean data indicate it is not always obvious which scales possess clearly favorable-unfavorable ends. Scale selection and wording, modification of instructions to respondents, and test-retest time interval affect scale reliabilities appreciably. Certain scales clearly differentiate LPCs better than others. Apparently, a transient rather than durable state is being measured.
