Abstract
Sensitive relationship forming as managerial dimension; the evaluation of a developmental programme. Interpersonal effectiveness in management is conceptualised as sensitive relationship forming with respect, realness, empathy and concreteness are core behavioural dimensions. As concurrent characteristics to these skills/ psychological optimal functioning is described with its specific intrapersonal, interpersonal and work-related characteristics. A developmental programme for the stimulation of sensitive relationship forming is constructed and applied to three groups of middle managers. The psychological evaluation shows a significant increase in all four core behavioural dimensions as well as psychological optimal functioning in terms of reality contact, emotional maturity and internal locus of control.
