Using Qualitative Data Analysis Software for Literature Reviews

This post is about my search for a qualitative data analysis (QDA) software solution for writing literature reviews. I review ATLAS.ti 8 and NVivo for Mac.

One of the challenges of writing a dissertation is compiling, organizing, and synthesizing sources. Reference managers such as Mendeley and EndNote are great for inserting bibliographic information into text documents or grouping sources by chosen tags, but they are not great for coding and analyzing connections between documents or keeping track of ideas and thoughts. Note-taking software such as Evernote is great for taking notes from classes or articles, clipping webpages, and organizing thoughts, but again, there is limited functionality for drawing connections between bodies of literature or visualizing connections. Hence the need for a software capable of organizing, coding, and connecting concepts, ideas, and themes.

Both NVivo and ATLAS.ti are designed for executing qualitative (text based) research. To be fair, neither program is specifically designed for writing literature reviews, however, literature reviews are essentially qualitative data analysis. This review is specific to the Mac versions of the two softwares which have slightly different functionality than the Windows versions.

Below are short bulleted lists of the pros and cons of each program. I ended up choosing ATLAS.ti because PDF rendering issues in NVivo were bad enough to be prohibitive of its use. I also have a feeling that knowing how to use ATLAS.ti will serve me in the future when I conduct qualitative research projects outside of literature reviews. However, had the rendering not been a problem, NVivo is easier and more effective for the purpose of conducting lit reviews. One additional suggestion that may make coding texts easier is to get a subscription to Adobe Acrobat Pro (they have special student pricing too) and use the enhance PDF tool to OCR every PDF you plan on importing into ATLAS.ti or any other QDA program. This process help with text recognition when you are selecting and coding text.

NVivo for Mac

  • Easy to create and code documents
  • Allows document importation from citation managers such as Mendeley
  • Allows memos to be edited and coded just like core document files
  • Has text query capability
  • Provides summary of coded text with marker for source document (see screenshot below)
  • Easy to create code hierarchies wherein multiple codes can be subcategories of a higher level code


  • PDFs do not properly render leading to choppy, slow scrolling action and in some cases, total program freeze—this makes the program very slow to use
  • When viewing documents with coded text visible, there seems to be a bug that causes the view to default back to the original hidden setting instead of your preferred view

Pricing As of January 9, 2017:

  • Student annual subscription $103
  • Student Full subscription $570

ATLAS.ti for Mac

  • Easy to create and code documents
  • Decent PDF rendering and performance
  • Lots of functionality beyond coding including visualization, quantitative-type analysis of qualitative data, and network analysis capability
  • Sophisticated user interface


  • Cannot import bibliographic files with metadata and accompanying PDFs
  • Cannot code memos
  • Cannot edit documents even if they are in RTF or .docx formats
  • Cannot link memos to documents easily
  • Cannot easily create code hiearchies


  • 2-Year Student license $99


Neither tool is perfect: NVivo has performance issues, but good functionality for the purposes of a lit review. Maybe in the future, once they solve these issues, it will be a clear winner. For now, the bugs cripple the application beyond usability for me.

I’m in the early stages of getting to know ATLAS.ti and will post an update when I have new information to share.

Doctors Give In to Money

A depressing article on the state of psychiatric health care in the US. I read articles like this and wonder how America will survive. Do you think doctors are denying therapy to patients in Canada, Cuba and Europe? No, because doctors are not paid more to prescribe drugs in a 15 minute appointment over a 45 minute talk therapy session.  Research proves the effectiveness of talk therapy for depression and yet doctors see only dollar signs and cave to insurance companies paying more for drug prescriptions.

Cosmic Kitty Herbs – Greens for your Cat

Pica in grass

Fresh greens are an important part of the domestic cat’s diet. Although some dry foods contain plant derived nutrients, there is no substitute for fresh greens (grass). You may have seen the small pots of grass at the pet store which are expensive and only last about a week. There is another easier and less expensive option that goes by the brand name of Cosmic Kitty Herbs. These kitty herbs consist of a variety of grass seeds cats love.

To grow kitty herbs, pour a layer of seeds into a small to medium sized planter with organic soil and add water. Keep the seeds moist and in a warm place until they germinate. Your cat will start munching on the sprouts right away and continue to eat the grass until it matures and flops over. This is the point where you add more seeds to the same pot ensuring there is always a new crop coming up full of tender shoots your cat loves.

And, in case you are thinking, whose going to clean up the cosmic kitty puke after kitty eats the greens, my experience is the grass mixture does not cause the cat to puke as happens when cats eat grass from yard. Our cat noms on her greens every day and has turned into a regular grazer without a single vomit.

Cosmic Kitty Herbs come in 3 oz bags and cost under $4  and can be found at most pet stores and on-line. I think I even bought them at a regular grocery store in the pet section.
