This paper reports on a series of three studies. The aim of the first one was to investigate the main dimensions of the Type C construct. A questionnaire developed in a previous study was administered to a general population sample (N= 618). Factor analysis yielded five factors: Emotional Control, Rationality, Emotional Repression, Need of Harmony, and Understanding, but structural equation analysis revealed that only Emotional Control, Emotional Repression, and Understanding are dimensions of the Type C construct. The second study was intended to replicate the first. Data supported the results obtained previously. In the third study, a group of patients with cancer (N= 100) and a control group (N= 98) were compared on the basis of the said five factors. Results showed that cancer patients scored higher than control group in all of them, but differences were statistically significant only regarding Emotional Control, Rationality, and Need of Harmony. These findings are discussed in the light of previous research and theory in this field.
