This paper reports a study of adult clients' experience of "My Career Chapter," which is a theoretically-informed, qualitative career assessment and counselling procedure. "My Career Chapter" engenders personal exploration through a client's writing and reading aloud a career-related autobiography, which is formulated on the basis of structured steps and a sentence-completion process. In a predominantly qualitative, mixed method design (i.e., QUAL+quan), interpretative phenomenological analysis of six interview transcripts constructed three major clusters representative of clients' experiences: implications for instructions and guidelines; induction of personal contemplation and self-reflection; and positive emotional experience. Secondary quantitative data aligned with the primary qualitative results. The results of this study were consistent with and extend upon previous research; and were indicative of the safety and potential of "My Career Chapter" as a narrative career assessment and counselling procedure for adults.
