FEPSAC is partly composed of group members, meaning societies or organisations which support the aim of FEPSAC and which wish to develop sport psychology.
In order to become a full FEPSAC group member, the societies must have at least ten members.
Each full member is represented in the General Assembly by two delegates who have five votes each.
More than one group member of the same country is acceptable, as are groups with members from more than one country.
The following groups are currently registered with FEPSAC and have paid their membership fees at least for 2019:
Portugal: Sociedade Portuguesa de Psicologia do Desporto (SPPD)
United Kingdom: Association of Applied Performance Psychology (AAPP)
