Abstract

The management of many health disorders often entails a sequential, individualized approach whereby treatment is adapted and readapted over time in response to the specific needs and evolving status of the individual. Adaptive interventions provide one way to operationalize the strategies (e.g., continue, augment, switch, step-down) leading to individualized sequences of treatment. Often, a wide variety of critical questions must be answered when developing a high-quality adaptive intervention. Yet, there is often insufficient empirical evidence or theoretical basis to address these questions. The Sequential Multiple Assignment Randomized Trial (SMART)-a type of research design-was developed explicitly for the purpose of building optimal adaptive interventions by providing answers to such questions. Despite increasing popularity, SMARTs remain relatively new to intervention scientists. This manuscript provides an introduction to adaptive interventions and SMARTs. We discuss SMART design considerations, including common primary and secondary aims. For illustration, we discuss the development of an adaptive intervention for optimizing weight loss among adult individuals who are overweight.

    Meal replacements are effective for weight loss partly because they remove the need to decide what food to prepare and the time and effort to prepare it, and they provide a clear method for portion control and reduced energy intake.

    “MR is effective for weight loss, in part, because it alleviates the need for decision-making regarding what food(s) to prepare as well as the time and effort needed to prepare the food.It provides a clear and unambiguous method for obtaining portion control and accompanying reduction in energy intake.”
  • The paper relies on this without support.

    Meal replacements and trained ACT psychotherapists are costly or limited in availability.

    “Due to the cost of meal replacements (MR) and the cost and availability of trained ACT psychotherapists”

    ACT requires a time commitment from the individual that may be burdensome.

    “Furthermore, ACT requires a time commitment on the part of the individual, which may be burdensome.”

    A subset of people may do well enough over time with IBT by itself.

    “These perspectives are important since some proportion of individuals might benefit adequately in the longterm from IBT alone.”
  • The paper relies on this without support.

    Creating a high-quality adaptive intervention usually demands answers to many critical questions, yet empirical evidence or theoretical grounding for those answers is frequently lacking.

    “Often, a wide variety of critical questions must be answered when developing a highquality adaptive intervention.Yet, there is often insufficient empirical evidence or theoretical basis to address these questions.”
  • The paper relies on this without support.

    Many behavioral intervention scientists are still unfamiliar with SMARTs.

    “Despite their increasing popularity due to their real-world clinical appeal, and their fit in research aimed at developing high-quality adaptive interventions, SMARTs remain relatively new to many behavioral intervention scientists.”
  • The paper relies on this without support.

    Most healthy dieting and weight-loss programs include IBT.

    “IBT is incorporated in most healthy dieting and weight loss interventions.”
  • The paper relies on this without support.

    Many investigators lack sufficient empirical evidence or theoretical basis to form a high-quality adaptive intervention.

    “in many other cases investigators have insufficient empirical evidence or theoretical basis to form a high-quality adaptive intervention.”

    Investigators often face important open questions about optimal adaptive intervention design, such as the best first-stage treatment.

    “investigators often confront important open questions such as “What is the best first-stage treatment?””

  • Figure 3 caption identifies itself as the baseline-randomization design

    Minor

    The caption calls Figure 3 a variation of the design in Figure 3, with the duration decision moved from baseline to week 5. The body instead identifies Figure 2 as the baseline-randomization design and Figure 3 as its variation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-06, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-06 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
