Abstract
The Political Participation Scale (PPS), developed by Choichiro Yatani in 1982, is a comprehensive self-report instrument designed to measure the extent of an individual’s involvement, interest, and attitudes toward political activities. Originating from a Master of Arts thesis at Oregon State University, the scale provides a quantitative assessment of various facets of political participation, ranging from passive behaviors like media consumption and discussion to active behaviors such as voting, campaigning, and contacting government officials.
Comprising 60 items measured on a 5-point Likert scale, the PPS aims to capture both external political actions and internal psychological states, such as feelings of political efficacy and perceptions of civic duty. It is particularly relevant for researchers studying political socialization and civic engagement among young adult populations.

Purpose
The primary purpose of the Political Participation Scale is to quantitatively assess the multifaceted nature of an individual’s engagement with the political system. The scale was developed to capture the spectrum of political involvement, moving beyond simple voting records to include personal interest, willingness to engage in political discussions, and attitudes toward governmental structure and policy-making.
The instrument was specifically utilized in Yatani’s original research to investigate the correlation between an individual’s level of political participation and their attitudes toward violence, providing a foundational tool for early research in political psychology and the study of political activism.
Construct
The core construct measured is Political Participation, defined broadly to encompass conventional political behaviors, such as voting and campaigning, as well as less formal activities, such as media consumption and political discourse among peers and family. Analysis of the 60 items suggests the construct covers several key dimensions:
- Political Interest and Knowledge: Measures engagement with political news and interest in political science courses (Items 13, 20, 48).
- Civic Duty and Voting Behavior: Assesses the perceived importance of voting and electoral responsibility (Items 11, 22, 58).
- Political Efficacy and Cynicism: Measures feelings of influence versus powerlessness regarding political outcomes and government decisions (Items 40, 44, 50).
- Active Campaigning and Direct Action: Captures willingness to participate in rallies, encourage others to vote, or contact officials (Items 7, 37, 47).
- Socialization and Discussion: Assesses the role of family, friends, and social circles in political engagement (Items 1, 9, 34).
Validity
Specific quantitative data regarding criterion validity or construct validity, such as correlations with established political scales or predictive power for future political behavior, is not explicitly detailed in the thesis abstract provided. However, the scale demonstrates high face validity, as the 60 items directly address a wide range of recognizable political behaviors and relevant political attitudes.
Reliability
The reliability of the Political Participation Scale was assessed using internal consistency methods. The original research reported a split-half correlation coefficient of .75. This coefficient was mathematically corrected for the full length of the 60-item instrument using the Spearman-Brown prophecy formula. This result indicates an acceptable level of internal consistency for a complex, multi-dimensional instrument used in social science research.
Factor Analysis
The original source content does not explicitly detail the results of a formal factor analysis performed on the 60 items. Given the breadth of the items—covering interest, efficacy, conventional participation (e.g., voting), and non-conventional attitudes (e.g., cynicism towards campaign contributions)—it is highly probable that the scale possesses a multi-factor structure, though the specific factors identified by Yatani (1982) are not specified here.

Permissions & Fee and Test Year
The scale was developed in 1982. As the instrument originates from an academic Master’s Thesis, it is generally considered available for non-commercial academic research purposes. Formal permissions for commercial use or modification should be sought by contacting the originating institution (Oregon State University) or the author. No specific fee structure is documented.
