TWO FACES OF NETWORK CLOSURE: A USER ADAPTATION THEORY OF IT SYSTEM USE

Abstract

THIS STUDY DEVELOPS A THEORY FROM ADVICE SEEKING AND GIVING NETWORK CLOSURES TO IT SYSTEM USE VIA THE UNDERLYING MECHANISMS OF A COGNITIVE-AFFECTIVE-BEHAVIORAL USER ADAPTATION. UPON THAT, A CONTINGENT THEORY OF IT COMPLEXITY IS JUSTIFIED. THE PROPOSED RESEARCH MODEL WAS TESTED VIA A FIELD STUDY OF A NEWLY IMPLEMENTED EMR SYSTEM, WHERE NETWORK DATA AND OBJECTIVE SYSTEM LOGS OF 104 DOCTORS WERE COLLECTED. PARTICULARLY, SEEKING-NETWORK CLOSURE IS POSITIVELY ASSOCIATED WITH COGNITIVE BUT NEGATIVELY ASSOCIATED WITH AFFECTIVE AND BEHAVIORAL USER ADAPTATION, WHILE GIVING-NETWORK CLOSURE IS NEGATIVELY ASSOCIATED WITH COGNITIVE BUT POSITIVELY ASSOCIATED WITH AFFECTIVE AND BEHAVIORAL USER ADAPTATION. FURTHER, IT SYSTEM USE IS POSITIVELY ASSOCIATED WITH COGNITIVE AND NEGATIVELY WITH AFFECTIVE USER ADAPTATION, WHEREAS NOT INFLUENCED BY BEHAVIORAL USER ADAPTATION. IN ADDITION, BOTH SEEKING AND GIVING NETWORK CLOSURES HAVE A GREATER IMPACT ON USER ADAPTATION FOR A COMPLEX IT SYSTEM. BOTH THEORETICAL
