Rule #1 of APA Text Citations
For each text citation there must be a corresponding citation in the reference list and for each reference list citation there must be a corresponding text citation. Each corresponding citation must have identical spelling and year. The purpose of the text citation is to briefly give readers the identity of the information you are citing, and allow them to find the information you provide in the reference list that enables readers to locate the exact piece of literature you used.

Corporations, Associations, Government Agencies, and Other Groups as Authors
Names of group authors are always spelled out in the first citation. The name should appear in the first text citation as it does in the reference citation. However, in following citations, they are sometimes abbreviated and sometimes not. How to decide: You need to give enough information in the text citation for someone to find the reference list citation.

Following Text Citations: (NIMH, 1999)

section, para. 4).
