Based on the ERG (Existence, Relatedness and Growth) theory, a scale was developed to evaluate the professional needs of psychological counsellors in China and its related factors were explored. A total of 209 counsellors participated in the study and completed two online questionnaires. The majority of participants were female (n = 163, 78%). The average age of participants is 41.00 (SD = 8.66). The results showed that the existence needs ([x-bar] = 4.49, SD = 0.60), relatedness needs ([x-bar] = 4.20, SD = 0.65) and growth needs ([x-bar] = 4.66, SD = 0.50) of counsellors were all at a high level. Work setting, marital status and regular supervision had a significant influence on the professional needs of counsellors. Counsellors working in private practice had more existence and growth needs compared to those working in institutions. Counsellors, who were married, had more existence and relatedness needs than those who were single. Counsellors without regular supervision had more existence, relatedness and growth needs.
