The present study investigated whether the women who applied for the self-management of well-being course Giving life more LUSTRE can be considered the target group that was intended. By comparing the course applicants with a random sample of community dwelling single women, it was found that, as expected, course applicants scored worse on well-being, loneliness, and negative affect, but not on positive affect, nor on self-management ability. It is concluded that the target group was reached only partly and that--even though the course has shown to be effective--a more specific recruitment procedure may further enhance its effectiveness.
