Purpose - The purpose of this paper is to examine the role of perceived external image and similarity in values, beliefs and interests with an organization's leaders and other members on organizational identification. Design/methodology/approach - The paper presents results of a field survey research in two non-work organizational contexts, a professional association, and a college business fraternity. Hypotheses were tested with ordinary least squares regression and mediation analyses. Findings - Perceived external image and perceived similarity with the organization's leaders and other members influence organizational identification. Perceived similarity partially mediates the relationship between external image and identification. Research limitations/implications - The study implements a cross-sectional design and relies on self-reports. The results have important implications for organizational identification and related behaviors both in work and non-work contexts. Practical implications - The study presents implications for enhancing member identification with an organization, which is related to increased involvement and continued membership. A positive external image may increase the likelihood that organizational members internalize values, beliefs and interests held by the organization's leaders and other members. Originality/value - The study is based on a model of identity orientation that differentiates across personal, relational, and collective orientations. It measures perceived similarity with social referents in values, beliefs and interests, and study traditionally overlooked non-work contexts.
