In health and social care health care professionals deal with many different service users and each them have personal preferences on the way and how they communicate. An example I am going to explain is with a service users that has Autistic Spectrum Disorder. Many young service users that suffer from this disorder may find it difficult to communicate or simply interact with others a challenge. A service user with ASD often prefer to be alone as they occasionally enjoy their own company. However some adults with ASD might like to communicate with other adult service users but lack the social skills to do so, so therefore find themselves becoming socially isolated. Many service users that suffer with ASD may find it difficult to maintain contacts due to the deficiency of the understanding of small talk and other agreements in a social environment this could loosely relate to Tuckman’s theory in particular stage 2 (storming) as the service user may fail in this stage due to the boundaries being made and the group coming together and the situation becoming too formal as many young sufferers with ASD have difficulty with verbal and also non-verbal communication as they do not fully understand the meaning and simple and even common hand gestures or either a health care professionals facial expressions even the tone of somebodies voice could confuse a service user that suffers with ASD so therefore they would feel overwhelmed when communicating in a group where there could be more than one service user or health care professional
