Training details

<p>This live-online, two-day training focusses on the Bayley Scales of Infant and Toddler Development, which is used to identify deficits in very young children across five major developmental domains: cognitive, language, motor, adaptive behaviour and social-emotional. This scale is ideal for use when delays or problems in early development are suspected to determine whether early intervention or further assessment are required. It indicates strengths, weaknesses, and competencies so that parents and professionals can properly plan for the child.</p>

<p>Below are the dates available for this training. We&#39;ll be in contact to secure your preferred date.</p>

							<li>Bayley-4 Technical Manual (paper or digital)</li>
							<li>Bayley-4 Stimulus Book (paper)</li>

						</td>
					</tr>
					<tr>
						<td>
						<p>The Scoring-Subscriptions provide a digital scoring option for paper-based administration. They allow manual entry of raw data to generate scores and reports.</p>

						<p>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.</p>

						<p>The Social-Emotional &amp; Adaptive Behavior Administration, Scoring and Report is a digital equivalent of the Social-Emotional &amp; 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.</p>

						<p>How do the integrated caregiver questions contribute to the scoring of an item?</p>
						</td>
					</tr>
					<tr>
						<td>
						<p>For certain questions a caregiver response is possible for scoring the item, see the example below:</p>

						<p>Ask caregiver,<strong> &quot;When you say the name of a familiar object, does [insert child&#39;s name] look at the object you named often, not often, or not at all?&quot;</strong></p>

						<p>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? </p>
						</td>
					</tr>
					<tr>
						<td>
						<p>The Caregiver Question should not be used in every item where it is an option or where a score of &#39;2&#39; 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.  </p>

			<h3>Digital Administration and Scoring</h3>

						<td>
						<p>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?</p>
						</td>
					</tr>
					<tr>
						<td>
						<p>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.</p>

						<p>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.</p>

						<p>Is there any data on differences between administration using paper vs. digital formats?</p>
						</td>
					</tr>
					<tr>
						<td>
						<p>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.</p>

						<p>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&#39;s performance on the two tests are similar (no significant difference).</p>

						<td>
						<p>How do I administer Bayley-4 digitally?</p>
						</td>
					</tr>
					<tr>
						<td>
						<p>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.</p>

						<p>The Social-Emotional &amp; Adaptive Behavior questionnaires can be administered remotely via a secure email link.</p>

						<td>Can you pull up the original eval and add to it for re-evals?</td>

						<p>Growth Scale Values are included in Bayley-4. These are useful for re-evaluation purposes and are available for both paper and digital administration.</p>

						<p>For paper administration statistical significance is also available to evaluate change in Growth Score Values between two administrations.</p>

						<p>How are growth scale values reported?</p>
						</td>
					</tr>
					<tr>
						<td>
						<p>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.</p>

						<p>The GSVs have a mean of 500 and a SD of 25. Because of their construction, GSVs cannot be meaningfully compared between subtests or subdomains. GSVs enable the measurement of an individual child&#39;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&#39;s peers and can track growth over time.</p>
