Measures of controlled and autonomous motivation drawn from SDT have been shown to have a mediating role in MI interventions[ 38 ]. Rogers used the term non-directivity, but this term, which is often misunderstood, was clarified by Grantwho distinguished between principled non-directivity and instrumental non-directivity.
The mother completes the measure and hands it back to the social worker. Motivation can be dramatically altered by small inputs. More importantly, the content, process and nature of the interactions are provoked by the questioning of the social worker.
The transformation is difficult to predict in part because the system is sensitive to initial conditions, i. The person finds meaning in his or her "suffering. The more a person argues for a position, the greater his or her commitment to it often becomes.
As such, while social work might value the relational qualities of empathy, unconditional positive regard and genuiness, or indeed the notion of an actualising tendency, it is theoretically misleading to refer to these relationship qualities as person-centred unless they are coupled with the stance of principled non-directivity, which we have shown is incompatible with what is required of modern social work practices.
