to the development of Autism Spectrum disorder because it can increase developmental delays even more than just the genetic factors. Though it is known that genetic factors do play a role because that is the primary development of a child, it is important to consider other aspects in the way this study did to achieve results that will help in the understanding of Autism Spectrum disorder and decrease the likelihood of the epidemic. 42

GENETIC AND ENVIRONMENTAL FACTORS OF AUTISM SPECTRUM DISORDER Discussion and Limitations There are often limitations to every study because research can generally be improved to better the findings in every specific field. In concordance with general research, this specific study including many limitations primarily because of its design. Some of the limitations to this study consist of a small sample size, that it was done over a span of almost 4 years, the ability the participants had to lie or give invalid information, and the ethnicity of the participants was not focused on and that genetics. Each of these limitations hurt the effectiveness of this specific study even though the results of the study enhanced research in the field of Autism Spectrum disorders. Sample size is a large issue when it comes to any study because there are many rights that participants have that can affect the sample size. Since participants have the right to drop out at any point, this study was negatively affected because the nature of the study required for participants to agree in spending about four years participating in this study dedicating themselves to daily logs throughout prenatal and postnatal care when other influences were on their mind during the time. Time management for participants in this study also affected sample size because taking the time to fill out the daily logs and attend meetings often conflicted with time spent with children, work and household obligations. Since the study was also done over 4 years, the same size dwindled because the dedication to complete it was rigorous. Longitudinal studies are often difficult because not only do the results take long for researchers to gather all of the data but it is hard to keep participants willing to see the end results by what they are participating in and ultimately help the current child’s life and children they may have in the future in the long run. Longitudinal studies also require a lot of funding and support due to the duration and the compensation that must be given for the amount of time and energy spent on the 43

GENETIC AND ENVIRONMENTAL FACTORS OF AUTISM SPECTRUM DISORDER study to participants and other expert providers. Due to the duration of the study as well, the participant could also have become lazy and given inaccurate information. Though inaccurate information can be given in any study, the likelihood of it occurring in a longitudinal study like the current study where in person meetings are a primary source of communication, it is often hard to lie. However, many participants in this study lied about the amount of exposure they had
