I neither strongly agree or disagree but tend to disagree. For me, the original message of the Buddha is mind-related. In this aspect, I disagree. Psychology is also mind-related. But the original message of the Buddha also included skilful means (i.e., skilful behaviours) for daily living, relationships, etc. Psychology may have an over emphasis on mind or introspection, so psychology may miss some of the Buddha's message here. Buddha's path is threefold (sila, sati/samadhi, panna) whereas often the psychology path is two-fold (sati/samadhi, panna) . Just my opinion.
