Communication is a crucial component in all steps of the health care process. Therefore, it is important to have knowledge about the communication skills of the whole health organization. From the socio-cognitive perspective, collective efficacy beliefs are the main indicators of the capacity of functioning of the system. This work aimed to contribute to the validation of the English version of Health Profession Communication Collective Efficacy Scale (HPCCE scale) a self-report questionnaire measuring hospital doctors' beliefs to succeed as a group to meet the needs of internal and external communication and of communication with patients, examining the structure, reliability and convergent validity. This study was a cross-sectional investigation conducted using snowball sampling. The participants were 287 doctors working at different hospitals in UK. Explorative factor analyses and Rasch analysis confirmed the one-factor solution. Results revealed high internal reliability. The HPCCE scale correlated positively with Social Self-Efficacy. The English version of HPCCE is a valid instrument to measure communication efficacy beliefs in hospital, involving different type of doctors. It can contribute to the implementation and evaluation of management interventions in a health organization aimed at its optimization.
