Abstract

OBJECTIVE: The current study is a secondary analysis of the Live SMART trial, a randomized controlled trial comparing a behavioral weight loss (BWL) condition delivered via smartphone (SMART) to a group-based BWL condition (GROUP) and a control condition (CONTROL). Given the established importance of self-monitoring for weight loss, the aims were to evaluate bidirectional associations between adherence to self-monitoring and weight change and to examine the moderating effect of treatment condition on these associations. METHOD: Adults with overweight/obesity (n = 276; 83% women; 92.8% White; Mage = 55.1 years; Mbody mass index = 35.2 kg/m2) were instructed to self-monitor dietary intake, daily weight, and physical activity minutes via paper diaries in GROUP and CONTROL and via a smartphone application in SMART. All participants were weighed monthly at the research center. Adherence to self-monitoring was assessed via examination of self-monitoring records. RESULTS: Generalized linear mixed models revealed that adherence to self-monitoring of dietary intake, self-weighing, and physical activity for each month was associated with weight change throughout that month, such that increased frequency of self-monitoring led to greater weight loss (ps < .001). For the GROUP condition only, poorer weight losses in 1 month were prospectively associated with poor adherence to self-monitoring the following month (ps ≤ .01). CONCLUSIONS: Results provide evidence of a bidirectional association between self-monitoring and weight change. Better self-monitoring was consistently associated with better weight loss across intervention and tracking modalities. Poorer weight loss was prospectively associated with poorer self-monitoring in group treatment, suggesting that social influences could drive adherence in this form of treatment.

    The direct association between self-monitoring and weight change, and the moderating effect of treatment condition, had not been evaluated in Live SMART.

    “Importantly, the direct association between self-monitoring and weight change, and the moderating effect of treatment condition, has not been evaluated in Live SMART.”
  • The paper relies on this without support.

    Earlier work has mostly taken the self-monitoring–weight change link to be one-directional.

    “Moreover, prior research has largely assumed a unidirectional relationship between self-monitoring and weight change”
  • The authors state this as an assumption.

    Participants who missed clinic visits or did not submit a record were assumed to have zero days of self-monitoring.

    “Participants who did not attend clinic visits or did not turn in a record were assumed to have zero days of self-monitoring.”
  • The authors state this as an assumption.

    Participants who did not submit self-monitoring records were assumed to have conducted no self-monitoring.

    “Further, assuming that participants who did not submit records conducted no self-monitoring could have introduced some degree of bias, especially for the GROUP and CONTROL conditions who were required to submit their records in-person or via mail, as opposed to the records of SMART, which were retrieved electronically and thus required no effort to submit.”
  • The paper relies on this without support.

    Body mass index, age, sex, income, education, and race/ethnicity have been correlated with weight change in previous investigations.

    “All models controlled for body mass index, age, sex, income, education, and race/ethnicity, as these variables have been correlated with weight change in previous investigations.”
  • The paper relies on this without support.

    Self-monitoring behaviors are jointly prescribed in behavioral weight loss interventions.

    “Since self-monitoring behaviors are jointly prescribed in BWL, this study examined the effect of self-monitoring each behavior (e.g., diet) while controlling for adherence to self-monitoring the other behaviors (e.g., self-weighing, physical activity).”

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

Statistics recomputed

Every reported test result, recomputed from its test statistic and degrees of freedom. A result shows as not adding up only once an independent check has confirmed it.

  • Consistentz = 3.49reported p < .001 · recomputed p < .001

    “z=3.49, p < .001”

  • Consistentz = 2.67reported p = .01 · recomputed p = .008

    “z=2.67, p = .01”

  • Consistentz = 2.83reported p = .005 · recomputed p = .005

    “z=2.83, p = .005”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Final summary overlooks a treatment-dependent association

    Major

    The final discussion says treatment and tracking modality did not produce different patterns of association. Earlier results report that the association between physical-activity self-monitoring and weight loss differed by treatment condition.

  • Final summary denies reported treatment-condition interactions

    Major

    The final summary says treatment and tracking modality did not produce different association patterns, but the results report significant interactions between treatment condition and prior weight loss for all three subsequent self-monitoring measures.

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.

Claims read under definition version 3 (extract-v3) on 2026-09-28.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-09-28.

Cited sources are checked by gpt-6-sol.

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.
