Purpose: The current review sought to bring light to the issue of an underexplored career phenomenon--career indecision. Career indecision is a significant developmental stage in one's career life and has been a prominent topic in vocational psychology research in the past decades. However, it has received scant scholarly attention in the human resource development (HRD) field. Besides, the career indecision literature, in general, is lacking theoretical refinement and analytical review. The present study aims to stimulate HRD scholars' interests by providing an introductory context for understanding the richness and potentialities of researching career indecision in the HRD area. Design/methodology/approach: To address the gap, the author conducted an integrative review (Torraco, 2005, 2016) of 60 peer-reviewed articles and synthesized the existing knowledge of career indecision. More importantly, antecedent and outcome factors associated with career indecision were identified and analyzed. Findings: A nomological network about career indecision was provided. Besides, the results of the integrative review revealed several omissions in the career indecision literature. Building upon that, implications for HRD research and practice are presented and discussed. Originality/value: As an initial attempt to synthesize career indecision literature, this study sought to stimulate HRD professionals' interest in examining this underexplored career phenomenon.
