Internal communication from a happiness management perspective: state-of-the-art and theoretical construction of a guide for its development

Abstract Objective This study aims to conduct a literature review and meta-analysis on the use of Happiness Management strategies in internal communication. The objective was to extract theoretical constructs of dimensions and indicators for the development of a guide for its application, validated by a panel of experts. Methods A systematic literature review and meta-analysis was performed under the protocol of the PRISMA Extension Guide of articles indexed in the Scopus database (2019–2024). The total number of extracted documents (n = 479) was screened based on the inclusion criteria, and the sample was delimited by 49 studies. Subsequently, after reading and analyzing the research, the dimensions and indicators of internal communication from a Happiness Management perspective were clustered. This guide was submitted to a panel of 13 experts who determined the reliability and validity of the construct and content using the Content Validity Index (CVI). Results The dimensions and indicators emerging from the literature were validated with an average ( $$\overline{\mathrm X}$$ X ¯ ) of 3.36/4, achieving a level of inter-judge agreement (CVI) of 0.86, an excellent agreement of 86%, and an average score of 2.90/4 (high). The guide was composed of 9 dimensions of internal communication: Attitudes of the leader, employer or supervisor, Climate and communication policies, Feedback and recognition, Organizational environment and structures, Peer and informal communication, Organizational culture and business perspective, Employee-organization relationship, Communication media and platforms, and Employee attitudes, which brought together 103 variables. These dimensions were then reorganized into the three macro-dimensions of the Happiness Management philosophy: (1) active construction of a healthy work environment and well-being, (2) formation of employees’ positive personality, and (3) active emotional experience during the working day to build the internal communication development guide from the Happiness Management perspective. Conclusions Integrating Happiness Management into internal communication can significantly enhance employee well-being and organizational effectiveness. The validated framework provides a detailed guide for aligning internal communication strategies with the Happiness Management principles.
