WMS-IV on iPad – part 1

Another great post by Debbie Anderson - enjoy!

It was a joyous day for me when the long-promised WMS-IV administration appeared on Q-interactive.  I suspect only a few (if any) of you have tried it, so here’s a run down of each of the subtests.
Visual Reproduction I:
You still need the pencil and paper response booklet for this section – so don’t forget that.  On the examiner screen it gives you the verbatim instructions to read.  The items are displayed on the client iPad, for the exact 10 second exposure.  So if you lose concentration, it takes it off the screen for you at the right time, so that the test is administered correctly.  You still have to remind the client to draw the items, and then swipe onto the next one.  It’s very smooth and easy to administer.  If you are quick about it, you can score it as you go (or most of it).  After the administration screen, there is a screen with all the scoring items for VR listed (with explanation and examples available when you touch on them).  For some you, you will be able to score on the fly (eg if the item is obviously correct or a 0), but for others you will have to come back to.  You can signal that you want to return to a screen later by touching the red flag in the top right hand corner, or it will do that for you if you don’t put in all the scores.  If you do put in scores, it gives you the total score and age scaled score on the final screen of this section.

Here’s the fun part, it starts counting down the timing for the delay (a small clock appears on the right).  You can tap on the clock to check how much time has passed.  It will change colours when it’s time to do something.  Unfortunately the colour change of the clock isn’t quite right at the moment, so make sure you check that actual time on the clock before recalling items.  Pearson are fixing it as we speak.  Nevertheless, having that on the screen – and not juggling the stopwatch is a big help.

Logical Memory I:
On the examiner’s iPad you see the story to read out.  When you swipe past that screen, you see the individual data points of the story listed.  You can just touch on them as the client recalls them, and voila – it works out the score for you!  If you have a client that is going too fast, or is difficult to understand, it records the audio for you, making it easy to listen to it and check your scoring later.  You can come back to it later, and indicate to look at it later, by tapping on the red flag in the top right hand corner.  You then swipe through to the second story (or whatever is age appropriate).  Don’t forget to scroll the screen up as there will be story details hiding down the bottom of the page when you are recording the answers.

Again at the completion of the subtest there is a screen with the score and its age scaled score.  I like to know how we are going, and this is great.  Again the clock starts at the end of this subtest (and the colour change element of this one is correct – it turns green after a 20 minute delay).

Spatial Addition
One of the things I didn’t like about the traditional administration of spatial addition was recording the responses for this subtest.  Now it’s much easier.  How it works is that the stimuli are displayed on the client’s iPad, and they still respond using the grid and coloured cards.  For the purists it isn’t the exact size as the grid, but pretty close.

The great part is that on the examiner’s screen you see the grid, and just have to copy what the patient is doing.  So no lifting the grid up, turning things in your head etc, you just copy what they do.  On your iPad screen you touch on the spots where they put the cards (once and it is blue, twice and it records white, three times for red and another tap to erase the answer).  The magic is that the iPad then works out if it is correct or not, and scores accordingly.

It also applies the discontinue and reversal rules –no flipping the pages around (and getting lost with them).  At the end of the subtest, it shows you the total score, and the age scaled score – much easier!

Visual Reproduction II
When it comes time to recall the VR items, you just need to swipe onto the subtest and it provides the examiner prompts.  The client draws them on paper, and if you can keep up (rarely, but I try) you night be able to score along – as each screen lets you indicate which figure was drawn and the scoring criteria for it.  Again if you can’t keep up, you can come back to it at your leisure.

Now the fun part – recognition.  Q-interactive doesn’t let you skip this – but it’s easy – the six options for each item come up on the client’s iPad, and they just have to touch on their choice.  If they want to change their mind, you can remove their response (on the examiner’s iPad) and let them put in the answer they want.  Lovely and easy.

Logical Memory II
Recall scoring is provided point by point, just like in the administration phase, and it records the response and you just touch on what the client says (i.e. just touching on the idea if it is correct rather than writing it out).  For the recognition component, the administration screen shows you what to read, and you just touch if the client’s answer was yes or no, and it tallies it up for you.  Again at the end you get a screen saying the scores and age scaled score.

Phew! That’s half the WMS-IV – next time the other half.
