One way to assess sleep problems is by identifying the individuals sleep routines and patterns they engage in during the day leading up to sleep. Once their patterns and routines are identified this will help show how to best start correcting these routines into healthy patterns. One can also watch the individuals sleep patterns (i.e. are they sleeping through the night, waking up in the middle of the night, going to sleep late, waking up before 6am, etc.).
One way to treat teen sleeping problems is by establishing a routine with the teen. Getting them involved and wanting to change their sleep patterns. Working on establishing healthy sleep patterns (i.e. more physical exercise, meals, meal time, set wake up times). By getting the teen involved they feel like they are being listened to which is more motivating to them to want to make these changes versus people just telling them what to do.
