Mental Health Scales App

The desired test subject can be quickly found by name using the search bar. As characters as added to the search field the list of subjects is filtered down to include only those subjects whose name matches.

The search bar is hidden under the navigation bar. Just swipe down to expose it.

To initiate a test just tap on the subject's name. To enter subject details or change them tap on the Information button.

Test subjects are given an alternate identifier, which can be specified automatically by the app or by the user, for example, a medical chart number. The alternate ID is used to identify the subject when exporting test results. The subject's name is never used.

Test sessions begin with an instructions screen. The user can tap on the controls at the bottom of the screen to move through the scale questions, or swipe from right to left on the screen to go forward, or swipe from left to right to go backward.

A summary is produced for each test, including a numerical score and its interpretation according to the authors of the rating scale. This provides an aid to diagnosis, but should not be taken as a diagnosis in itself.

The answers for each question (not shown here) appear in the summary, allowing a quick review of the results.

The summary can be emailed or sent via the Messages app back to a central location, or printed using AirPrint. The alternate ID assigned to the subject is used here, never the actual name.

Data security is a prime consideration. Data in the app is secured by Apple's hardware-level encryption on passcode-protected devices. An in-app password, which is backed up by a security question selected from a choice of three provides two additional security modes. Version 2.4 adds the ability to use Face ID as an alternate to the password on iPhone X and later. Touch ID can be used on phones with Touch ID for the same purpose.

Secure Mode prevents unauthorized launch of the app. Client mode allows the test subject to use the device for a self reporting scale without being able to access data outside the current test, or that of others.

Anyone attempting to access the application with security turned on will only see the security screen. Access can be achieved by entering the password, or if that is lost, answering the security question.

On Touch ID and Face ID equipped devices Touch ID or Face ID can be used instead of the password to access the app.

The BMI calculator allows the practitioner to monitor the effects of medications on the client's weight. The waist circumference is also recorded. The BMI is color coded to indicate if it is in a normal or abnormal range.

Version 2.3 adds the ability to specify a default age for the subject (person). This reduces the amount of scrolling of the date picker needed when entering the birth date of a new subject. For example, if the practice consists primarily of older adults, the default age could be set to 65 years.
