According to the person-centred approach, human beings possess a natural capacity for growth. For this capacity to be activated, however, specific relational conditions are needed. Carl Rogers, the founder of the approach, described these as the six necessary and sufficient conditions for therapeutic change. They are not techniques or interventions, but qualities of the relationship. Their significance lies in creating a space in which a person can remain in contact with their own experience, recognise their needs, and gradually integrate them. 

This process rests on three fundamental conditions, without which nothing essential can take place in therapy. First, there must be real contact – an attentive meeting between two people, rather than merely sharing the space of a therapy room. Second, the client is in a state of inner incongruence, experiencing a discrepancy between what they are living through and the way they function. Third, the therapist remains authentic within the relationship – not hiding behind a professional role, but being present as a real person. Together, these conditions form the foundation of a therapeutic relationship that sustains and enables the process of change.

Only on this foundation can what truly supports change begin to emerge – the quality of the relationship that develops between therapist and client. The therapist offers the client unconditional acceptance: without judgement and without pressure to be someone other than who they are. This is accompanied by empathy, understood not as a technique but as a genuine attempt to enter another person’s world – to see from their perspective and to follow what is alive and meaningful for them. It is also essential that the client can genuinely feel these attitudes and recognise them as real. Only then does it become possible to gradually become more familiar with one’s own experience and to integrate it into a more coherent whole. Change grows from within the relationship itself and the encounter it holds.
