A problem statement should always put the problem into context by indicating what is known about it, points out the precise issues the research wants to address, elaborate the importance of the problems and what will be done. It should elaborate on an undesirable gap between the current state-level of events and the desired future-state level of events. The problem statement should not include possible causes or solutions but should include measures of the problem in order to quantify the gap.
You never made mention of your research topic so we can't tell you exactly what to include in your problem statement. Nevertheless, problem statement is simply a written statement of the problem you seek to solve by the time you are done with the study. You should build it up such that readers can identify the problem
