      Teenagers are always in a constant struggle to establish their identities. Therefore, in the effort to overcome self-doubt and momentarily forget about their struggles, most teens end up indulging in substance abuse. As such, the family is regarded as the fundamental unit in society hence having a major influence on childrens emotional and social development. Based on an array of psychological researches, parental and family factors have a chief position to substance abuse in the long run (Coatsworth & George, 2019). Therefore, parents behaviors and parenting styles directly affect the childrens behaviors, abilities, and self-esteem. Children who grow up under positive parenting are more likely to possess lower behavioral problems hence more likely to overcome temptations to substance abuse. On the other hand, children who undergo negative parenting such as rejection are more likely to become substance users. Generally, parents have a major impact on their childrens decision not to use drugs hence the need to equip parents with proper training on parenting skills to prevent substance abuse among teenagers.
5.    A brief and general goal statement phrased as To provide parents with the knowledge and skills to enhance family bonds and strengthen parents to prevent teen substance

6.    A 1-paragraph training synopsis. This is an informal statement in general terms of what will be detailed very formally in the training.  It is what will happen during training. For now, describe how you will go about training the target audience. 
        Parents are the strongest influences and the primary role models for children hence necessitating the need for parents to talk to their children about substance abuse early. The training involves strategies aimed at enhancing positive family relationships, family observation and management and communication of family principles and anticipations (Meja et-al, 2019). This training is aimed at strengthening parenting skills such as increasing emotional attachment, increased communication, problem-solving skills, and family management practices. It might also include opportunities for the parents to bond with their children by spending positive time together.  The program will combine; efforts to shape family management by training parents to enhance their parenting skills and further incorporating family practice sessions. That is, sessions will involve parents attending their training groups and eventually combining the parents and children for practice sessions to monitor progress.
