I think it most important needs of these people " need to attract the attention of others".
No human being is not a remote island!!!!!! Without proper online communication with others , conditions adversely affects mental and emotional states and behavior .
Specifically in women who live alone there is a tendency .
Psychological care , security , a more suitable job offer , bringing them to the community and people!!!!
Most of the prostitutes in sex industry may be feeling an isolation in the society, due to various reasons. They may not be taking part in the social functions being organised and are generally feel themselves 'marginalised' in the society. This social isolation may move to the next generation as well. Having interactions with some of those in the field as a researcher, I strongly felt that they wanted a 'decent living' for their children, better education facilities, health care, employment, etc. More importantly a 'social acceptance' to their children, apart from the social identity of the mother, is one of the prime needs. It hurts them much when their children are deprived of opportunities owing to their 'social status'. What they expect, want and demand from the society for themselves and their children is 'nothing but respect as a human being' and a decent living conditions in a harmonious society for them and them and their family members.
One of the main needs of victims of human trafficking is psychological care. Many of the women who are admitted to my program suffer mainly from PTSD, and often times they have been diagnosed with comorbid disorders, due to their upbringing. Depression, self esteem issues, and confidence are also main factors that prevent them from succeeding in life after prostitution.
