### pnt: Computer adaptive forms of the Philadelphia Naming Test
An R package and web-app for administering the Computer Adaptive Philadelphia Naming Test (PNT-CAT).
**[PNT-CAT Technical documentation](https://rbcavanaugh.github.io/pnt)**
### About
This application allows clinician users to administer adaptive (PNT-CAT) and static versions of the Philadelphia Naming Test ([Roach et al., 1996](https://mrri.org/philadelphia-naming-test/) and generate output that provides scores on a common T-score metric, where the expected mean and standard deviation of persons with aphasia are 50 and 10, respectively. Users have the option of downloading performance data and a pdf-report of the results. Please note that the app does not store any data beyond a single user-session.
Comments, feedback, and bug reports are encouraged. Please submit as an issue: https://github.com/rbcavanaugh/pnt/issues.
```{r, results = 'asis', echo = F}
print(citation("pnt"), bibtex = F)
```
For users looking for a deeper dive into principles of item-response theory and computer adaptive testing in aphasia, we recommend:

### Installing & Using the application
There are a number of ways to use the application (see below). However, please note that server resources are finite, and therefore **we ask that researchers use option 2 for the following reasons:** (1) The version of the app remains consistent throughout the research study (option 1, 3, and 4 may change based on any updates to the app), (2) There is an inactive time-out limitation on the free online version of the app to keep server costs reasonable, which means that a long break (>15 minutes) without activity may cause you to lose your current session. (3) Both the free online version and `shiny::runGithub()` function require a stable internet connection and data will be lost if an internet connection is lost.
**Detailed installation instructions can be found here: https://github.com/rbcavanaugh/pnt/wiki**
#### 1. Online
The app is now online at https://william-hula.shinyapps.io/pnt-cat/
#### 2. Local Installation
The app can be installed locally via `remotes::install_github()`
#### 3. Local installation on RStudio Cloud
The app can be installed and run from RStudio Cloud (https://rstudio.cloud/)
if R/Rstudio can't be installed locally.
#### 4. Remote access to the app, run locally
The app can also be accessed via `shiny::runGitHub()`
#### 5. Clone the repository
If desired, the repository can be cloned, and run locally.
```
git clone https://github.com/rbcavanaugh/pnt.git
```
