The address examines qualities of behavioural therapists since the inception of ABMA. Attention is also given to current issues that require objective analysis; especially issues of individual and social responsibility, the role of families, and adult relationships. There is a need to identify frameworks that assist objective analyses of social situations. A behavioural decision-making approach appears useful for analysing responsibility, as the approach includes concepts to describe both individual choice and social pressures, allowing an assessment of the extent to which individuals or groups should change. There is also a need to find objective measures of values, both of individuals and of small groups. We can expect to see further changes in behavioural theories as more concepts and principles are introduced by behavioural practitioners who address current social problems.
