Therefore, the SOBC sees value in providing other researchers in the field with information regarding measures that work and measures that fall short for specific targets. Our goal is to make meaningful progress and develop replicable and effective interventions in behavior change science. Why would we share measures that are not validated? The SOBC Research Network values open, rigorous, and transparent research. If a measure is Not validated, then change in the measured target was not reliably associated with Behavior Change. If a measure is Validated, then change in the measured target was reliably associated with Behavior Change. Once a measure has gone through these three stages, it will then either be Validated or Not validated according to SOBC Research Network standards. Evidence relating to each stage includes at least one peer-reviewed publication or original data presentation (if no peer-reviewed research is available to support the claim) and is evaluated by SOBC Research Network Members and experts in the field. The third stage of validation requires demonstration that the measure can be Influenced there must be evidence that the measured target is malleable and responsive to manipulation. For example, if the proposed measure is a questionnaire, the score on the measure should indicate the activity of the target process, and it must have strong psychometric properties. The second stage of validation requires demonstration that the level and change in level of the chosen mechanistic target can be Measured with the proposed measure (assay). This evidence may include references for the proposed measure, or theoretical support for the construct that the proposed measure is intended to assess. The first stage of validation requires a measure to be Identified within the field there must be theoretical support for the specific measure of the proposed mechanistic target or potential mechanism of behavior change. The SOBC Validation Process includes three important stages of evaluation for each proposed measure: Identification, Measurement, and Influence. Within the SOBC Measures Repository, researchers have access to measures of mechanistic targets that have been (or are in the processing of being) validated by SOBC Research Network Members and other experts in the field.
#Backward digit span verification#
The experimental medicine approach involves: identifying an intervention target, developing measures to permit verification of the target, engaging the target through experimentation or intervention, and testing the degree to which target engagement produces the desired behavior change. The SOBC program aims to implement a mechanisms-focused, experimental medicine approach to behavior change research and to develop the tools required to implement such an approach. By integrating work across disciplines, this effort will lead to an improved understanding of the underlying principles of behavior change. The Science of Behavior Change (SOBC) program seeks to promote basic research on the initiation, personalization and maintenance of behavior change. (For proprietary reasons we are unable to upload the Digit Span Backwards scale.) The total raw score for backwards digit span is the sum of the item scores maximum backwards digit span total raw score is 16 points. The item score is the sum of the scores on the two trials for that item (range=0-2). For each trial, 1 point is scored for a correct response or 0 points for an incorrect response or no response.
#Backward digit span trial#
Both trials of each item are administered, even if the child gets Trial 1 correct. On each question the child repeats the numbers in reverse order of that presented aloud by the examiner (e.g., If the examiner says "5-6", the correct response would be “6-5” If the examiner says "5–1–7–4–2–3–8", the correct response would be "8-3-2-4-7-1-5"). For the purposes of our study, we used backwards only for a total of two trials of eight questions, or 16 total questions. The task consists of two items, forwards and backwards, and each item is composed of two trials of eight questions each. It assesses children’s ability to hold information in short-term memory and manipulate that information to produce some result. The Digit Span Task (Backwards-Only Child Version) measures working memory.
