The need for competence (Deci & Moller, 2005) concerns
supports for efficacy with respect to autonomously selected goals
or areas of growth. Therapists enhance the sense of competence
through providing both effectance relevant feedback and by providing
a structure to their activities that brings coherence and
direction to the work of therapy. Although the role of positive
feedback is well understood, the concept of structure, which
concerns the implementation of goals, strategies, and limits, is
often confused with control. Yet research in SDT suggests that
structure can be implemented in either controlling or autonomysupportive
ways (e.g., Grolnick, 2003; Koestner et al., 1984), and
this strongly moderates the likelihood of promoting proactivity and
internalization
