The sampling method is Stratified Random Sampling. The strength of this method is that it has provided greater precision to the study which also saved cost on the study (Bordens and Abbott, 2010). The weakness of the method is that it may need greater administrative efforts than the other sampling methods.

Parents of children with ADHD in the area are the population for this research study. Among the population, 15 parents of the children with ADHD are recruited as a sample. They were recruited by the health care professional to participate in the study. They were identified through their children. The selection of children was carried out sequentially from the patients' list who had already participated in the systematic diagnosis assessment within the duration of one year at the specialty clinic for children with learning, behavioral, and attention disorders.

Other inclusion criteria involves age between 6-12 at the time of assessment, parents able to speak and understand English language and the previous use of stimulant and/or non-stimulant medications.

Different instruments are used to conduct researches. These instruments are used according to the requirements and needs of the study. The instruments are the measuring tools through which researchers collect the relevant data from the related sample (Palta, 2003). In order to avoid the reliability and validity issues of the study, researchers must select the most appropriate instrument for their research so that they can collect the most relevant data for their study.

The researchers have used questionnaires in this research to collect the relevant information about the difference between parents choice of stimulant medication over the non-stimulant medication for their children with ADHD. The questionnaires used in this research included 25 questions. They had made questionnaires with the use of a set of questions related to the experiences of parents with ADHD medications. The questions covered different spheres of the topic which will help researchers know the difference. The questions were about what factors influence them choosing stimulant medication over non-stimulant medication, their previous use of medications, the advantages of the medications, etc.

One of the greatest advantages of questionnaires is that the information of the person filling the questionnaire is kept secret (Peat, 2011).
