The self-actualization concept: A content validation

Some 45 years after its original formulation by Rogers and Maslow, the self-actualization (SA) concept still needs further clarification. This study attempts to define this construct more precisely by assessing its essential attributes through a content validation procedure using the Delphi method. The results reveal the existence of a strong consensus among 26 international experts (francophone and anglophone; American, Canadian, French and Belgian) on 36 SA indicators. These characteristics help to better understand what the concept really means and were used as a basis for building a more valid SA measure instrument.
