This study examines a construct of relationship quality (RELQUAL) in Turkish business relationships, and appears to be the first of its kind in this region. The sample frame comprises the 500 largest companies in Turkey based upon revenue across multiple industries. The analysis yield support to the argument that continuity, trust, coordination, opportunism, commitment, formalisation, specific assets, dependence, satisfaction and cooperation are separate constructs that play an important role in creating relationship quality in Turkish business relationships. This study is of managerial and theoretical interest to executives and researchers since it provides a framework of constructs to be considered in corporate efforts in maintaining satisfactory levels of relationship quality, not only in Turkish business relationships, but it may also be applicable in other business relationships and countries.
