Caring is the core of nursing. In cancer care the concept of “caring” is considered as a multidimensional phenomenon, that constitutes a challenge for measurement. Many authors illustrate caring as a set of caring behaviours, including both existential aspects and nursing actions. Despite the availability of previous research caring behaviours are recognized as an issue worthy for closer examination, in different cultures. The purpose of this pilot descriptive, exploratory, study was to explore Hellenic nurses caring behaviours in cancer care. Materials and Methods: Data was provided by a convenience sample of 83 nurses working in 6 purposeful selected oncology settings all over the country. Participants completed a brief demographic form and the Caring Behavior Inventory (CBI) instrument consisted by four subscales-24 items measured in 6-point Likert scale. After permission was obtained CBI was forward and backward translated in Greek. Data were analyzed by Factor analysis. Results: The majority of the respondents were female (94%), aged 36−40 years old (30.6%), married (72%) and Technological Educational Institute (TEI) graduates (54.2%). The overall Cronbach’s alpha of CBI Greek version was 0.96. Factor analysis identified four factors (Professional knowledge and skills, Respectful defence to others, Positive connectedness and attentiveness, Assurance of human presence), corresponding to the original subscales of the CBI. Professional knowledge and skills was determined as the most important factor, with the items “Giving the patient’s medications and treatments on time” and “Knowing how to give shots” being the highest in the list. In addition items “Spending time with patients” and “Attentively listening to patient” were ranked higher by older and married than younger and single nurses. Moreover “Managing equipment skilfully” and “helping to reduce patient’s pain” items were ranked higher by more experienced nurses than those with less years of experience (p = 0.01). University graduates perceptions of caring behaviour “spending time with patients” was ranked less than TEI graduates (p = 0.01). Conclusion: Despite study limitations, the positive results of piloting CBI is encouraging for further research in Hellenic nurses caring behaviors.
