“…Six studies (Bohlmeijer et al, ; de Manincor et al, ; Fledderus, Bohlmeijer, Smit et al, ; Fledderus, Bohlmeijer, & Pieterse, ; Fledderus et al, ; Walker & Lampropoulos, ) investigated well‐being in adults with mild to moderate depressive symptoms using the MHC (Keyes, , , ) or the FS (Diener et al, ).
