Well-being Biomarkers (BIOSMILE) & Psychology Analyses in Women With Cancer After Hospital Clowns and Hosting Effects

The goal of this interventional study is to evaluate the impact of Hospital Clowns (HCs) intervention, besides to hospital hosting conditions, in the well-being of adult female patients during ambulatory chemotherapy. The main question\[s\] it aims to answer are: * Do the short-term HCs interventions during ambulatory chemotherapy may increase well-being of adult cancer patients in comparison to the hospital hosting conditions? * Do the short-term HCs interventions, besides the hospital hosting conditions, have effects on well-being biomarkers in association with psychological outcomes? Participants self-collect a sample of saliva followed by psychological assessment, at a first time-point (basal) and at a final time-point (\~after 90 minutes of basal) (pre- and post-test), during the chemotherapy treatment session. Researchers have compared an HCs intervention plus hosting conditions - experimental group, EG, and hosting conditions only - control group, CG, by the repeated measures of pre- and post-test of biomarkers in saliva and the psychological functioning evaluations, to see the degree of the impact of HCs intervention in the well-being of the patients in comparison with normal hosting conditions. Each HCs intervention lasts around 15 minutes, and it is performed in the middle of the procedure between pre- and post-test.
