Well ABA is defined as the application of scientifically derived principles and techniques to increase socially significiant behaviours. I know that is a mouthful. Basically what my job ias a behaviour support specialist involves is assessing people's behaviours in order to establish the function of the behaviour (what the behaviour is really saying) and building a positive behaviour plan to support that person to communicate that message skillfully and appropriately. The programme has three main parts - environmental changes, skills teaching and reactive strategies. ABA really fits into the skills element of a positive behaviour support plan - as this involves structured teaching techniques to support the person to learn effectively. You may have heard of ABA in the media recently? The skills i teach can range from basic self help skills such as getting dressed, brushing teeth, pesonal hygiene etc to higher skills such as appropriate social skills, communication skills, coping and tolerance skills, community integration, using a visual schedule etc. It really depends on what the person needs.
I know that is a lot of info but my job is so varied it is difficult to summarize it here! Hope this gives a bit of insight into what i do!
