People who use self-silencing behaviours are sacrificial individuals who suppress their needs and find it difficult to express themselves in order to maintain or improve their relationships with others. These feelings seem to be collecting themselves in the form of unexpressed anger, which makes self-accommodation a long-term bad relationship maintenance strategy because the focus is on getting the approval of others. On the other hand, perfectionism is a trait that implies the pursuit of infallibility and setting excessively high goals which are usually followed with a tendency to excessive self-criticism. The aim of this research was to examine the connection between self-silencing and perfectionism and to determine possible gender differences. The study included a total of 218 participants (72 men and 147 women) whose age on average was 23 years. Most of the participants were university students. The Multidimensional Perfectionism Scale (MSP-F) and the The Self-Silencing Scale were used to assess perfectionism and self-silencing. It was expected that there would be no gender differences in either self-silencing or perfectionism, and that these two constructs listed would be positively correlated. Apart from the fact that men have been shown to be using more of self-silencing behaviours than women, the hypotheses have been confirmed.
