Is halal universal? The impact of self-expressive value on halal brand personality, brand tribalism, and loyalty: case of Islamic hospitals

Purpose The purpose of this study is to examine the antecedents and consequences of halal brand personality in the hospital industry by comparing Muslim and non-Muslim Islamic hospital visitors. Design/methodology/approach Online questionnaires were distributed to 113 Muslim and 100 non-Muslim Islamic hospital visitors using a purposive proportional sampling technique. The structural equation modelling (SEM) method was used, which is appropriate for complex model testing. SEM was used for both the second-order model and multigroup analysis to compare Muslim and non-Muslim visitors. Findings Self-expressive value was significantly affected by halal brand personality. Self-expressive value was a direct antecedent of brand tribalism, which affects brand loyalty. Brand tribalism positively affected brand loyalty. No differences between Muslim and non-Muslim visitors were found, indicating that halal is a universal concept, particularly in the hospital brand personality context. Practical implications Islamic hospital marketing managers should empower visitors to build strong brand advocacy. These strategies may lead to new hospital visitors and can be achieved by creating user-generated content distributed via social media. User-generated content is a powerful form of brand advocacy, as non-customers do not view it as marketing. Originality/value This study provides insightful empirical contributions to brand literature by showing that halal is a universal and inclusive concept, relatively accepted by consumers regardless of their religious background. This study also offers managerial insights for hospital policymakers in developing strategic programs to strengthen Islamic hospitals' halal brand personalities.
