Telepractice and the WASI-II

Computers and connectivity

Two computers with audio and video capability and stable internet connectivity—one for the examiner and one for the examinee—are required. A web camera, microphone, and speakers or headphones are required for both the examiner and the examinee. A second computer screen or split-screen format on a large computer monitor for the examiner is helpful to allow a view of the digital administration and scoring manual, but the examiner can also use the paper format manual or the Q-interactive® platform. The second computer or large screen also tends to make sharing test content more straightforward for the examiner.

Teleconference platform

A teleconference platform is required. Screensharing capability is required if anything other than items with verbal stimuli are administered.

Image/screen size

When items with visual stimuli are presented, the digital image of the visual stimuli on the examinee’s screen should be at least 9.7” measured diagonally, similar to an iPad or iPad Air. Some teleconference platforms shrink the size of images, so the examiner should verify the image size in the initial virtual meeting. It is recommended that computer screens used for teleconference assessment be at least 15” measured diagonally. Smaller screens, such as those of iPad minis, small tablet PCs, and smartphones, are not allowed for examinee-facing content, as these have not been examined empirically and may affect stimulus presentation, examinee response, and validity of the test results. Similarly, presenting stimuli on extremely large screens has not been examined, so the same precaution applies. At the beginning of the testing session, the examiner may ask for a peripheral camera or device (as described later in this section) to be aimed to provide a view of the examinee’s screen to ensure that the examinee’s screen is displaying images in the correct aspect ratio and not stretching or obscuring the stimuli image.

Video

High-quality video (HD preferred) is required during the administration. Make sure the full faces of the examiner and the examinee are seen using each respective web camera. The teleconference platform should allow all relevant visual stimuli to be fully visible to the examinee when providing instruction or completing items; the view of the examiner should not impede the examinee’s view of visual test stimuli.

Screensharing digital components

Digital components are shared within the teleconference platform as specified in Table 1. There are two ways to view digital components in the Q-global Resource Library: through the pdf viewer in the browser window or full screen in presentation mode. Always use full screen (i.e., presentation) mode for digital components viewed by the examinee. This provides the cleanest presentation of test content without onscreen distractions (e.g., extra toolbars). Refer to Using Your Digital Assets on Q-global in the Q-global Resource Library for complete directions on how to enter presentation mode.

Test item security in the audiovisual environment

The examiner is responsible for ensuring test item security is maintained, as outlined in the Terms and Conditions for test use. The examiner should address test security requirements with the examinee (and facilitator, if applicable) during the informed consent process. The examiner should make it clear that the video should not be captured, photos should not be taken, and stimuli should not be copied or recorded, as this is a copyright violation. The examinee must agree that they will not record (audio or visual) or take photos or screenshots of any portion of the test materials or testing session, and not permit anyone to observe the testing session or be in the testing room (except for a facilitator, when necessary).

Peripheral camera or device

A stand-alone peripheral camera that can be positioned to provide a view of the session from another angle or a live view of the examinee’s progress is helpful. Alternately, a separate device (e.g., a smartphone with a camera or another peripheral device) can be connected to the teleconference and set in a stable position to show the examinee’s responses. The device’s audio should be silenced and microphone should be muted to prevent feedback. The examiner should guide positioning of the peripheral camera/device before administering Block Design (if the subtest is administered) and prior to subtests that elicit pointing responses (i.e., Matrix Reasoning and the Similarities picture items; refer to Table 1) so that the examiner can see the examinee’s real-time responses.

In a typical telepractice session, it is more feasible to make a document or moveable camera available in the examinee’s location. However, while social distancing is necessary, the only camera available may be a stationary camera integrated into the examinee’s laptop or computer screen. It is unrealistic to expect examinees to have peripheral cameras within their homes. It may be necessary for examiners to think creatively about how to use a smartphone in the examinee’s location to gain a view of the examinee’s responses if pointing responses are elicited. Prior to attempting this with an examinee, the examiner should work to become fluid and competent at directing examinees in these methods, which can require extensive practice with varied individuals and types of smartphones. In addition, this requires planning and practice in the initial virtual meeting to prevent technical difficulties, and so the examinee feels confident doing this when it is time.

Online instructional videos (e.g., here) demonstrate how a smartphone may be used with common household objects (e.g., books) to form an improvised stand upon which to position the device to provide a second-angle view of the examinee pointing at the screen. Typically, devices provide the best view of the examinee’s screen and pointing responses when positioned in landscape format. While using a smartphone as the peripheral camera is not an optimal solution for telepractice, it can be functional if executed well.

Gesturing

When gesturing to the stimulus book is necessary, the examiner should display it as a digital asset onscreen and point using the mouse cursor. Refer to Table 1 for specific instructions by subtest.

Audio considerations

High-quality audio capabilities are required during the administration. An over the head, two-ear, stereo headset with attached boom microphone is recommended for both the examiner and examinee. Headphones with a microphone may be used if a headset is not available.

Audio check

The examiner should test the audio for both the examiner and examinee in the initial virtual meeting and at the beginning of the testing session to ensure a high-quality audio environment is present. Testing the audio should include an informal conversation prior to the administration where the examiner is listening for any clicks, pops, or breaks in the audio signal that distorts or interrupts the voice of the examinee. The examiner should also ask if there are any interruptions or distortions in the audio signal on the examinee’s end. Any connectivity lapses, distractions, or intrusions that occurred during testing should be reported.

Manage audiovisual distractions

As with any testing session, the examiner should do everything possible to make sure the examinee’s environment is free from audio and visual distractions. If the examiner is unfamiliar with the examinee’s planned physical location, a visual tour of the intended testing room should be given during the initial virtual meeting. The examiner can then provide a list of issues to address to transform the environment into one suitable for testing. For example, remove distracting items, silence all electronics, and close doors. The examiner should confirm that these issues have been addressed at the time of testing. If possible, the examinee should be positioned facing away from the door to ensure the examiner can verify through the examinee’s camera that the door remains shut and can monitor any interruptions. The examiner should confirm that all other applications on the computer, laptop, or peripheral device are closed, the keyboard is moved aside or covered after the session is connected, and alerts and notifications are silenced on the peripheral device. Radios, televisions, other cellular phones, fax machines, smart speakers, printers, and equipment that emit noise must be silenced and/or removed from the room.

Lighting

Good overhead and facial lighting should be established for the examiner and examinee. Blinds or shades should be closed to reduce sun glare on faces and the computer screens.

Disruptions

The examiner should record any and all atypical events that occur during the testing session. This may include delayed audio or video, disruptions to connectivity, the examinee being distracted by external stimuli, and any other anomalies. These can be noted on the record form or in the Q-interactive notes and should be considered during interpretation and described in the written report.

Copyright

Permission must be obtained for access to copyrighted materials (e.g., stimulus books, response booklets) as appropriate. Pearson has provided a letter of No Objection to permit use of copyrighted materials for telepractice via a teleconference platform and tools to assist in remote administration of assessment content during the COVID-19 pandemic.

Blocks

Block Design may only be administered when a professional facilitator is present. The blocks should be provided to the professional facilitator before the testing session. It is not recommended to allow a parent/guardian/caretaker to present blocks for Block Design, nor to attempt to have the examinee scramble or present their own blocks.

Digital assets

The examiner should practice using the digital stimulus book until its use is as smooth as a face-to-face administration. It is not recommended that the examiner display items from the paper stimulus book on a camera.

Considerations

Table 1 contains the specific telepractice considerations for each subtest to be administered. Table 1 of the WISC–V and the WAIS–IV telepractice guidance provides the corresponding information that is needed if WASI–II information is being supplemented with WISC–V or WAIS–IV subtest scaled scores to obtain the WISC–V FRI or the WAIS–IV PRI (as discussed in the introductory section of the present document).

Input and output requirements and equivalence evidence

The examiner should consider the input and output requirements for each task, and the evidence available for telepractice equivalence for the specific task type.

Telepractice Versus Face-to-Face Administration

Preliminary research has compared results obtained in telepractice and face-to-face administration modes. Several tasks drawn from the Wechsler scales have produced evidence of equivalence in telepractice and face-to-face modes for examinees with a variety of clinical conditions (Cullum et al., 2006, 2014; Galusha-Glasscock et al., 2016; Grosch, et al., 2011; Hildebrand, et al., 2004; Ragbeer et al., 2016; Stain et al., 2011; Temple et al., 2010; Wadsworth, Dhima, et al., 2018; Wadsworth, Galusha-Glasscock, et al., 2016). A study of the Wechsler Abbreviated Scale of Intelligence (WASI; Pearson, 1999) equivalence of telepractice administration compared with face-to-face administration in examinees with intellectual disability produced mean FSIQ scores that differed by less than 1 standard score point (Temple et al., 2010). A study of the Wechsler Intelligence Scale for Children–Fifth Edition (WISC–V; Wechsler, 2014) administered by telepractice compared scores assigned by a psychologist sitting in the room with the examinees and another psychologist interacting only through telepractice with the examinees in a small sample of children with specific learning disabilities. This research demonstrated that the primary index scores and the Full Scale IQ corresponded to a high degree (Hodge et al., 2019). A similar study conducted on speech-language tests provided similar results (Sutherland et al., 2017). Other studies support equivalence of tasks that are similar to some of the WASI–II subtests with nonclinical examinees using telepractice compared with face-to-face administration and scoring (Galusha-Glasscock et al., 2016; Wright, 2018a, 2018b). In addition, a meta-analysis of telepractice studies provides support for telepractice and face-to-face mode equivalence across a variety of neuropsychological tests (Brearly et al., 2017).

While equivalence data on similar measures are relevant, practitioners should be mindful that more research is needed to establish equivalence in all ages and for all tasks on the WASI–II. Additional caveats and cautions are described in Grosch et al. (2011). Also, most telepractice-based studies were conducted with volunteer subjects in controlled environments. When social distancing is key (such as during the COVID-19 pandemic) some examinations may need to occur in examinees’ homes, and it should be noted that very little research has been done about remote assessment in private homes.
It is important to consider the conditions under which equivalence studies of telepractice and face-to-face assessment modes were conducted and attempt to reproduce these as closely as possible if testing via telepractice. Typical telepractice studies that support telepractice and face-to-face equivalence involve the examiner becoming very familiar with the teleconference platform by using it for its intended purpose for several hours and administering tests (even those that are familiar in face-to-face mode) multiple times to “practice examinees.” Some studies that have established telepractice and face-to-face mode equivalence involve a professional facilitator. However, preliminary research conducted and described by Lana Harder (Stolwyk et al., 2020) with parents serving as in-home facilitators who managed audiovisual needs and response booklets found no significant differences across modes. Finally, the examinee is typically in an office- or school-based setting. Therefore, if in-home assessment is taking place, it is advisable to prepare a similar environment as much as possible as described in the Telepractice Environment & Equipment section.

Digital Versus Traditional Format

Telepractice involves the use of technology in assessment as well as viewing onscreen stimuli. For these reasons, studies that investigate assessment in digital versus traditional formats are also relevant.

A number of investigations of the Wechsler scales have produced evidence of equivalence when administered and scored via digital or traditional formats to examinees without clinical conditions (Daniel, 2012a, 2012b; Daniel et al., 2014; Raiford, Zhang, et al., 2016). In addition, equivalence has been demonstrated for examinees with clinical conditions, such as intellectual giftedness or intellectual disability (Raiford et al., 2014; Raiford, Zhang, et al., 2016), attention-deficit/hyperactivity disorder or autism spectrum disorder (Raiford, Drozdick, et al., 2015; Raiford, Zhang, et al., 2016), or specific learning disorders in reading or mathematics (Raiford, Drozdick, et al., 2016; Raiford, Zhang, et al., 2016). However, it is important to note that these studies were not conducted remotely or via video conference.

Evidence by Subtest

Table 2 lists each WASI–II subtest, the input and output requirements, the direct evidence of subtest equivalence in telepractice–face-to-face and digital–traditional investigations, and the evidence for similar tasks. The abbreviations in the Input and Output column correspond to the various input and output requirements of each subtest, and a key appears at the bottom of the table. For example, brief spoken directions as an input requirement is abbreviated as BSD. The numbers in the evidence columns correspond to the studies in the reference list, which is organized alphabetically in telepractice and digital sections. For clarity, each study is denoted either T or D, with T indicating the study investigated telepractice–face-to-face mode, and D indicating the study addressed digital–traditional format.

Appropriateness

The examiner should first ensure that a telepractice administration is appropriate for the examinee and for the purpose of the assessment. Clinical judgment, best practice guidance for telepractice (e.g., APA Services, 2020; ASPPB, 2013; IOPC, 2020), information from professional organizations and other professional entities (e.g., licensing boards, legal resources, professional liability insurance providers, payors), consultation with other knowledgeable psychologists, existing research, and any available federal or state regulations should be considered in the decision-making process. Consideration should be given to whether the necessary administrative and technological tasks involved in a telepractice session can be accomplished without influencing results.

Preparedness

Before initiating test administration, the examiner should ensure that the examinee is well-rested, able, prepared, and ready to appropriately and fully participate in the testing session.

Facilitator role

If using a facilitator, the role of the facilitator must be explained to the examinee so participation and actions are understood.

Headset

It may not be appropriate or feasible for some examinees to use a headset due to behaviour, positioning, physical needs, or tactile sensitivities, or if a headset is not available. Clinical judgement on the appropriate use of a headset in these situations should be used. If a headset is not utilized, the examiner’s and examinee’s microphones and speakers should be turned up to a comfortable volume.

Mouse

On some teleconference platforms, the examiner can pass control of the mouse to allow the examinee to point to indicate responses; this is an option if it is within the capabilities of the examinee. However, best practice guidelines provide cautions about this. For example, the IOPC guidelines suggest examiners be alert throughout administration, return control of the screen once the task is finished, and never leave the computer unattended while the examinee has control over the examiner’s computer (IOPC, 2020).

Practice

During the telepractice setup, and before administering to any actual examinee, the examiner should rehearse the mechanics and workflow of every item in the entire test using the selected teleconference platform so that the examiner is familiar with the administration procedures. For example, a colleague could be used as a practice examinee.

Standardized procedures

The examiner must follow the administration procedures of face-to-face administration as much as possible. For example, if a spoken stimulus cannot be said more than once in face-to-face administration, the examiner must not say it more than once in a telepractice administration unless a technical difficulty precluded the examinee from hearing the stimulus.

Administrative and technological tasks

In order to conduct a smooth telepractice session, audiovisual needs and materials must be managed appropriately. The initial virtual meeting involves the examiner, examinee, and/or the facilitator (if used), and is the opportunity for the examiner to provide information about the audiovisual needs and materials. During the initial virtual meeting, the examiner should provide training in troubleshooting audiovisual needs that arise during the testing session, including camera angle, lighting, and audio checks. The examiner should provide verbal feedback to guide camera adjustment, checking the onscreen video shown by the peripheral camera/device to provide information about how to reposition it until the proper view is shown. The examiner should emphasize that no materials should be opened until the examiner provides instructions to do so, if applicable. The examiner should also expect to provide verbal guidance about these issues during the testing session. Refer to the Telepractice Environment & Equipment section and to Table 1 for specific subtest telepractice considerations.

If used, the facilitator is to assist with administrative and technological tasks and not to manage rapport, engagement, or attention during the testing session. The examiner should direct them not to interfere with the examinee’s performance or responses. Any other roles and responsibilities for which an examiner needs support, such as behaviour management, should be outlined and trained prior to the beginning of the testing session. The examiner is responsible for documenting all behaviours of the facilitator during test administration and taking these into consideration when reporting scores and performance.

There are special considerations for written reports describing testing that takes place via telepractice.

The professional completing the written report should state in the report that the test was administered via telepractice, and briefly describe the method of telepractice used. For example, “The WASI–II was administered via remote telepractice using digital stimulus materials on Pearson’s Q-global system, and a facilitator monitored the administration onsite, during the live video connection using the [name of telepractice system, e.g., Zoom] platform.”

The professional should also make a clinical judgment, similar to a face-to-face session, about whether or not the examiner was able to obtain the examinee’s best performance. Clinical decisions should be explained in the report, including comments on the factors that led to the decision to conduct testing via telepractice and to report all (or not to report suspect) scores. In addition, it is recommended that the report include a record of any and all atypical events during the testing session (e.g., delayed video or audio, disruptions to connectivity, extraneous noises such as phone ringing or loud dog barking, person or animal unexpectedly walking into room, the examinee responding to other external stimuli). Notes may be recorded about these issues on the record form. List and describe these anomalies as is typical for reporting behavioural observations in the written report, as well as any observed or perceived impact on the testing sessions and/or results, and consider these in the interpretation of results. For example, “The remote testing environment appeared free of distractions, adequate rapport was established with the examinee via video/audio, and the examinee appeared appropriately engaged in the task throughout the session. No significant technological problems or distractions were noted during administration. Modifications to the standardization procedure included: [list]. The WASI–II subtests, or similar tasks, have received initial validation in several samples for remote telepractice and digital format administration, and the results are considered a valid description of the examinee’s skills and abilities.”
