PurposeThe purpose of this study is to investigate whether leader-follower similarity in construal level of the work, which indicates the degree of abstraction applied to mental representation of the work, influences the quality of interpersonal relationship at work.Design/methodology/approachFirst, an interview study was conducted to adapt the work-based construal-level (WBCL) scale. Then, a survey study was conducted for hypothesis testing. Data collected from 245 matched supervisor-subordinate dyads were analyzed using multi-level modeling.FindingsResults revealed that dyadic similarity in work-domain construal level is positively related to leader-member exchange (LMX) quality. As a leader and a follower become similar to each other in terms of mental representation (i.e. construal level) of work, they experience higher relationship quality.Originality/valueThis study enhances the current knowledge of the role of cognition and cognitive similarity in leadership processes.
