Telephone interviews with 809 adults aged 18 years and over in April 2004, revealed that 83% believe it is acceptable for parents to smack their children, including one in six (16%) who believe it is always acceptable and a further two thirds (67%) who believe there are some circumstances in which it is acceptable. Just over one in ten (13%) believe it is unacceptable in any circumstances.
