Du Toit shares results of her early research that underpin the VdTMoCA today. Her research suggested growth and recovery of volition and also action follows a sequential pattern, the stages of volitional growth and recovery and those of action appear to be interdependent, and that the growth and recovery of volition must be influenced by the nature and content of the action elicited from the patient. The term Creative Ability is described as coming into use to denote the combination of an inner volition or drive towards action, and the externalisation or expression of the volition in action. Specific factors as components of creative ability were identified in the research process such as the individual's ability to relate to materials and objects, people and situations, ability to control the negative effects of anxiety; the degree of initiative or originality in thought and action, and the quality and degree of effort. Those criteria led to the development of descriptive terms for each level of volition and each parallel level of action, the nine levels of creative ability. Creative response and creative capacity as well as key concepts of creative ability are defined to the audience. The latter part of the paper includes a description of the quality of volition and action specifically to handling of materials, relating to people and product creation for each level of creative ability. Du Toit concludes by stating that recognition of the aspects of volition and action in a patient will enable the therapist to map the direction of treatment from the earliest stage of illness.
