Both in-text citations and the references must be prepared according to the Publication Manual of the American Psychological Association (APA), Seventh Edition (2020).

When citing publications, preference should be given to the latest, most up-to-date sources. Citing the latest sources can help to ensure that the paper is relevant and timely, and that it reflects the latest developments in the field.

It is the responsibility of the authors to ensure the accuracy of the references in their article. All sources must be properly cited, and the citations must be formatted correctly.

To avoid plagiarism, it is necessary to acknowledge other sources in your paper through in-text citations. For every in-text citation, a corresponding reference list entry must be provided.

The APA in-text citation style includes the author's last name and the year of publication, such as (Field, 2005). If quoting directly from a source, the page number should also be added, such as (Field, 2005, p. 14).

If an ahead-of-print publication is cited, the DOI number should be provided in the reference list.

The reference styles for different types of publications are presented in the following examples.
