If you access PubMed via the SIT Library website you can check if the library has the full-text version of any article.
You will, however, need to set up your own NCBI account - for more details please check the My NCBI section of the PubMed LibGuide.
If the article is not available through the SIT Library, you can check to see if the full-text is available via the National Library Board's eResources like Proquest Central, Academic Search Premier, JSTOR.
Go to Google Scholar through the link below and again search for the title.
If the full text is not available through either of these methods, ask a Librarian
