She became interested in psychology and, on returning from India, spent some time working at the Tavistock Clinic in London, alongside fellow Scot, Hugh Crichton-Miller. She became a candidate for training at the Clinic but before completing her studies, her husband took up a position at Edinburgh College of Art, and they moved back to Scotland. She set up a private practice in Edinburgh in 1929. In 1939, during the burgeoning of the Child Guidance movement, she established the Davidson Clinic with the aim of bringing family support and advice to the community, along the model of the pre-war Tavistock Clinic. She retired from the clinic in 1967 and the following year was awarded the OBE.
