This research aims to proofs the existence of antecedents in the intention to conduct research leading to professional commitment. The gap in the current practice is the need to increase Indonesia's academic rank in the world due to a decrease in various indicators. As for previous studies, limited information on professional commitment by researchers is found especially in Indonesia. Researchers propose personal and external related variables; personal variables include Attitude toward Behaviors, and Perceived Behavioral Control; whereas external related variables include Subjective Norm, Institutional Support and Research Related Policy. Study to 235 academicians in Indonesia produce a conclusion that perceived behavioral control is the only variable in TPB that is the antecedent toward the intention. Meanwhile, external related variables fail to show its significance, with the exception of Research Related Policy, showing the need in finding other extraneous variables in the future. Intention to do research can impact researcher's professional commitment.
