The dimensionality of partisan strength and political independence

This study explores the dimensionality of partisan strength and independence by analyzing the relationships between the traditional four-point partisan strength scale, a strength of independence scale, and other relevant variables in the 1980 and 1984 NES/CPS election studies. In particular, the investigation centers on the possible different explanations for independence. The findings tend to support explanations for independence that concern party attachment and civic responsibility. The data show that partisan strength and independence are separate components of party identification. Previous findings based on the use of the traditional partisan strength scale may therefore need to be reconsidered.
