Wong also conducted lectures to nurses and other student groups. In March 1968, F Y Long was employed as the second psychologist. Long, who completed his clinical psychology training at Sydney University, added impetus to what Wong had earlier embarked upon. Personality testing, including the use of projective techniques, became part and parcel of psychological assessment. Hitherto the psychologists conducted mainly IQ testing. Soon after, behaviour therapy was applied for the first time in Woodbridge Hospital on a case of stammering but psychologists were not accorded any therapeutic functions. In May, psychological assessment was extended to the selection of renal patients for haemodialysis at the Renal Unit in the Singapore General Hospital. In July 1968, Dr Ho Eng Siong (designated child psychiatrist) and Long commenced weekly child guidance clinic for cases from Gimson Boys' School and welfare homes. Following Wong's resignation in October 1969, Long continued to implement what his predecessors had established but focused more on clinical work at Woodbridge Hospital and services to SGH, TTSH and Prisons Department. During the early 1970s, with the Child Guidance Clinic in full-time operation, demands for psychological help were heavy. At the direction of the then Minister for Health, the late Mr Chua Sian Chin, a five-year projection for psychological services within the Ministry of Health was submitted in April 1970. Subsequently, several psychologists (David Oon, Lee Mee Mee, MC Foo and Lily Ng) were added to the staff at Woodbridge Hospital and Child Guidance Clinic. Behaviour therapy became the psychologists' recognized role after 1971 when Professor S Rachman, a renowned pioneer in the field, convinced the psychiatrists at Woodrbdige Hospital of what the psychologists could contribute to the clinical management of psychiatric patients. A programme of token economy was successfully carried out in a chronic ward in 1973. The psychologists with the other members of the psychiatric team were involved in rehabilitation projects in Woodbridge Hospital. Psychology lectures for various groups of nurses at the School of Nursing in SGH, the WH School of Psychiatric Nursing as well as to students at the Department of Social Work & Social Administration, University of Singapore were in high demand. Since the beginning of 1970, psychological services were extended to the Ministry of Social Affairs and the Prisons Department. John Elliott was appointed the first psychologist in the Ministry of Social Affairs (later known as the Ministry of Community Development). A few years later, Loh Yan Poh became the first psychologist serving full-time in the Prisons Department.
