Hola, "a primary purpose" al final de este párrafo me tiene un poco confundida y no sé si traducirlo como "el propósito principal" o "uno de los propósitos principales" o "un propósito principal"... ¿Qué opináis? Espero que el contexto os sirva de ayuda. Muchísimas gracias =)


Adler believed that the primary motivation of all human beings is to belong and feel significant, and that psychologically healthy people seek belonging and significance in socially useful ways. By “socially useful” we mean two things. First, we mean that a person’s attempts to connect and be important invite a positive response from those around her. Second, we allude to a concept coined by Adler that he called Gemeinschaftsgefühl, sometimes translated as “social interest.” Adler believed that mental health can be measured by the degree of an individual’s positive contribution to his or her community. Thus, a primary purpose of behavior is to act on that motivation to achieve a sense of belonging and significance.

De este modo, uno de los propósitos principales del comportamiento es trabajar esa motivación para lograr un sentido de pertenencia y reconocimiento.
