Very few empirical studies have been conducted to investigate which items of Western mediation models are cross-culturally applicable to other mediation developing countries without any cultural issues, irrespective of whether the county has a Western legal tradition and culture or not. This study attempted to identify the most important items of the mediation service commonly influencing the parties' satisfaction and their intention to reuse mediation in three different countries: Korea, the UK and Hong Kong. Questionnaire surveys were undertaken to two hundred fifty construction companies in Korea and Hong Kong, and to two hundred and eighty companies in the UK. In the questionnaire, they were asked if they were satisfied with the mediation service in each country. For the criteria to judge, ten items widely used in the UK models were applied: (1) Pressure Exerted from Mediators to Settle; (2) Voluntary Agreement; (3) Mediation Process Atmosphere; (4) Facilitative Mediators; (5) Reflection of Parties' Opinions in a Settlement; (6) Confidentiality; (7) Impartiality; (8) Cost; (9) Time; and (10) Preservation of Relationships. The collected data was analysed by using SPSS (13.00) and Minitab (15.00) statistical programmes: One-way Analysis of Variance (ANOVA), T-test, Cross-Tabulation Analysis, Chi-Square Test for Independence and the Binary Logistic Regression Analysis. The results revealed that six items were important, showing a strong relationship between the parties' degree of satisfaction with the mediation service and their intention to reuse mediation in the future, irrespective of country (Mediation Process Atmosphere, Reflection of Parties' Opinions in a Settlement, Confidentiality, Preservation of Relationships, Time, and Impartiality). On the other hand, it was found that other items such as Pressure Exerted from Mediators to Settle, Voluntary Agreement, and Facilitative Mediators worked differently in each country.
