Title Page: A running head, main title, author and affiliation information should be included in the Title Page. All this information should be placed in the top half of the page; centered; and the initials of each word should be capitalized. The title should be reflective of the main theme of the manuscript.

Abstract: This part should follow the title page and start after the centered title “Abstract”. It should start without indentation and include a comprehensive summary composed of 150-250 words. The “Abstract” should mainly comprise the aim of the study, variables or associations investigated, brief information about participants, method, and results. Any information that is not included in the manuscript as well as cited statements should also not be included in the “Abstract”. Keywords, not more than five words or phrases, should be added below the “Abstract”. (APA-Sample Abstract).
