If I have a Bayley-III kit, can I upgrade to Bayley-4? If so, what are the options?
| |
Materials are available to purchase separately; however, it is more expensive to upgrade this way than to purchase a new kit, i.e. the items required to upgrade would be:
- Bayley-4 Administration Manual (paper or digital)
- Bayley-4 Technical Manual (paper or digital)
- Bayley-4 Stimulus Book (paper)
- New Manipulatives (small set of disks (3); cat puzzle; memory cards; ducks; pennies and penny bank; large disks (6); small car)
- For manual administration and scoring:
- Cognitive, Language, and Motor Forms, and Motor Response Booklets (pkg of 25 of each)
- Social-Emotional & Adaptive Behavior Record Forms (pkg 25)
- Caregiver Report (pkg of 25)
- For digital administration and scoring:
- Q-global: Cognitive, Language and Motor administration, scoring & report and Motor Response Booklets
- Q-global: Social-Emotional & Adaptive Behavior administration, scoring and report

What is the difference between Bayley-4 Q global Scoring Subscriptions and Bayley-4 Q global Reports?
| |
The Scoring-Subscriptions provide a digital scoring option for paper-based administration. They allow manual entry of raw data to generate scores and reports.
The Cognitive, Language and Motor Administration, Scoring and Report is used for the on-screen administration of these domains, and is a digital version of the Cognitive, Language, and Motor Record Form. This is for the Examiner to use and complete.
The Social-Emotional & Adaptive Behavior Administration, Scoring and Report is a digital equivalent of the Social-Emotional & Adaptive Behavior record form. This is a caregiver questionnaire which can be emailed to the caregiver with a secure link to complete or can be completed within your office on an internet enabled device.

How do the integrated caregiver questions contribute to the scoring of an item?
| |
For certain questions a caregiver response is possible for scoring the item, see the example below:
Ask caregiver, "When you say the name of a familiar object, does [insert child's name] look at the object you named often, not often, or not at all?"
Score
2 points, Often
1 point, Not often
0 points, Not at all
| |
For those items for which a structured/observation score and a Caregiver Question score can be obtained, is it recommended to ask the caregiver question in every instance where mastery (i.e. a score of 2) is not assigned based on the structured item administration or observation?
| |
The Caregiver Question should not be used in every item where it is an option or where a score of '2' is not assigned. The intent of the caregiver questions is not to optimize scores as much as possible. Rather, they are to be used when a response is ambiguous, the child is not cooperative, or if the behavior may have a greater likelihood of occurring in familiar surroundings. Frequent discrepancies between what is observed during testing and the caregiver question responses raises questions regarding the validity of Caregiver Question scores, and clinical judgement should guide interpretation.

Digital Administration and Scoring
|
Can you log in to the digital scoring and save the score report so that another discipline can enter and score their section for the same kid?
| |
This is possible and depends on how the account is set up. Some Q-global users intentionally set up their accounts so that all their team members can view their examinees as a group (rather than just the ones they have entered). Of course, an account can also be setup so that users can only see their own examinees. This is a choice made when the account is set up.
If an account is set-up so that it is in the same hierarchy as other accounts, then the examinee record can be moved from one account to another for other disciplines to enter and score their section. Examinee records cannot be moved to an account within a separate entity / hierarchy.
| |
Is there any data on differences between administration using paper vs. digital formats?
| |
The digital administration of Bayley-4 is a digital record form, the child does not interact with the administration device (e.g. tablet/laptop), the administration guidelines between paper and digital are the same.
As part of the Bayley-4 validation we conducted a study comparing performance on Bayley-III (paper scoring) and Bayley-4 (digital scoring). The data indicates that the children's performance on the two tests are similar (no significant difference).
| |
How do I administer Bayley-4 digitally?
| |
The digital administration uses Q-global and combines the record form and administration manual for more streamlined administration. It is optimized for the screen-size of a tablet (e.g. iPad) or larger. Although it will work on a smart phone it will not be a good user experience. Q-global can be used on any device that has internet. You cannot use Q-global without internet access.
The Social-Emotional & Adaptive Behavior questionnaires can be administered remotely via a secure email link.
| |
Will the program be able to let the examiner know when you should stop correcting age for premature babies?
| |
It is recommended to adjust for prematurity up to 24 chronological months, however, the platform will allow you to adjust beyond this age. There is on-screen text advising the recommended ages for adjusting.
| | Can you pull up the original eval and add to it for re-evals? | |
Growth Scale Values are included in Bayley-4. These are useful for re-evaluation purposes and are available for both paper and digital administration.
For paper administration statistical significance is also available to evaluate change in Growth Score Values between two administrations.
| | What happens if your internet connection drops during administration? | | Information is continually backed up in Q-global, if a connection drops during administration then any data entered will have been saved. Once you're able to reconnect, the session will continue from where you left off. | | Is offline administration available? | | Offline administration is not available currently. The back-up option is to use paper administration, and enter the scores manually, a subscription version of Bayley-4 on Q-global to facilitate this. | | Can Bayley-4 be administered remotely via telepractice? | | The Social-Emotional & Adaptive Behavior Questionnaire can be administered remotely. Guidance to support telepractice administration of Bayley-4, including the Cognitive, Language and Motor scales is available here |
Psychometrics
|
How are growth scale values reported?
| |
Growth scale values (GSVs) provide a score metric that does not involve age-based comparisons. Their purpose is for tracking performance across repeated test administrations. If a raw score increases upon a repeat administration, the GSV also increases.
The GSVs have a mean of 500 and a SD of 100. Because of their construction, GSVs cannot be meaningfully compared between subtests or subdomains. GSVs enable the measurement of an individual child's progress or improvement in an absolute sense. Although the normative scaled scores provide information about a child relative to his or her peers at a given time and may show little change over time, the GSV can provide an ability to estimate independent of one's peers and can track growth over time.

Do the Bayley-4 norms account for children from culturally and linguistically diverse backgrounds?
| |
The normative sample was aligned with the latest US census data and included children from culturally and linguistically diverse backgrounds including bilingual children.
