Comparison of the acceptability and benefits of two mindfulness-based interventions in women with breast or gynecologic cancer: a pilot study
Open accessAbstract
Purpose: The aim of this study was to compare the relative benefits and acceptability of two different group-based mindfulness psychotherapy interventions among women with breast and gynecologic cancer. Methods: Data from 42 women who completed an 8-week mindfulness-based cognitive therapy (MBCT) program comprising 22 contact hours were compared to data from 24 women who completed a 6-week mindfulness meditation program (MMP) comprising 9 contact hours. Distress, quality of life (QOL), and mindfulness were evaluated pre- (T1) and post-intervention (T2). ANCOVA was used to analyse the relationship between intervention type and T1 score on outcome variable change scores. Participants’ perceptions of benefit and acceptability were assessed. Results: The participants did not differ on clinical or demographic variables other than MBCT participants were more likely than MMP participants to have a past history of anxiety or depression (p =.01). Scores on distress, QOL, and mindfulness improved from T1 to T2 with medium to large effect sizes for the MMP (p =.002, d =.07; p =.001, d =.08; p =.005, d =.06, respectively) and MBCT (p <.001, d =.06; p =.008, d =.04; p <.001, d =.09, respectively) interventions. ANCOVA showed no main effect for intervention type on outcome change scores and no interaction between intervention type and respective T1 score. Distress and mindfulness scores at T1 had a main effect on respective change scores (p =.02, ηp 2 =.87; p =.01, ηp 2 =.80, respectively). Both programs were perceived as beneficial and acceptable with no differences between the intervention types. Conclusions: Within the limits of a small, non-randomized study, these findings provide preliminary support for the utility of a brief mindfulness intervention for improving distress and QOL in a heterogeneous group of women with cancer. Abbreviated interventions are less resource intensive and may be attractive to very unwell patients. © 2014, Springer-Verlag Berlin Heidelberg.

Inconsistent p-value: t (59) =.33, p = .44
MinorThe paper reports p = .44 here; recomputing from the test statistic and its degrees of freedom gives p = .743 (two-tailed). The check cannot tell whether the statistic or the p-value is the misprint.
Reported p = .44 · recomputed p = .743

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.

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.
MMP mindfulness change has the wrong sign
MajorThe reported MMP FMI means rise from 33.30 at T1 to 39.43 at T2. Under the stated T2-minus-T1 definition, the change is positive 6.13, not negative 6.13; this also affects the reported between-group comparison.
Reported -6.13 · recomputed 6.13
“Mean (SD) change scores on the FMI for the MBCT and MMPs were 6.84 (7.53) and -6.13 (9.41), respectively.”
Abstract understates both distress effect sizes tenfold
MinorThe abstract reports distress effect sizes of 0.07 for MMP and 0.06 for MBCT, whereas the results report 0.7 and 0.6, respectively.
“p=.002, d=.07; p=.001, d=.08; p=.005, d=.06, respectively) and MBCT (p<.001, d=.06; p=.008, d=.04; p<.001, d=.09, respectively)”
“Mean DASS-21 (SD) scores changed significantly from T1 to T2 for MBCT participants from 40.65 (21.02) to 29.30 (18.71) (p=.001, d=0.6); and for MMP participants from 41.54 (27.49) to 24.29 (13.39) (p=.002, d=0.7).”
Five of six sessions is not 80% attendance
MinorAttending five of six MMP sessions amounts to approximately 83.3%, rather than the stated 80%.
Reported 80 · recomputed 83.333333
“attended at least 5 of 6 sessions, or 80%”
MBCT past-meditation percentage does not match its count
MinorThe 12 MBCT participants listed with past meditative practice represent approximately 28.6% of the 42 completers, not 27%.
Reported 27 · recomputed 28.571429
“Past meditative practice, n (%) 12 (27) 9 (38)”
MMP tertiary-education percentage does not match its count
MinorTable 2 lists 15 tertiary-educated participants out of 24 in the MMP group. That is 62.5%, not 38%.
Reported 38 · recomputed 62.5
“Tertiary educated (bachelor degree/higher) , n (%) 25 (60) 15 (38)”
Abstract understates both quality-of-life effect sizes tenfold
MinorFor QOL, the abstract gives effect sizes of 0.08 for MMP and 0.04 for MBCT; the results give 0.8 and 0.4.
“p=.002, d=.07; p=.001, d=.08; p=.005, d=.06, respectively) and MBCT (p<.001, d=.06; p=.008, d=.04; p<.001, d=.09, respectively)”
“Mean FACT-G (SD) scores changed significantly from T1 to T2 for MBCT participants from 63.80 (17.61) to 69.28 (16.37) (p=.008; d=0.4) and for MMP participants, from 71.40 (17.43) to 82.17 (14.56) (p=.001, d=0.8).”
MBCT past-treatment percentage does not match its count
MinorTable 2 gives 26 MBCT participants with a past history of formal treatment, out of 42 MBCT completers. That is approximately 61.9%, not 52%.
Reported 52 · recomputed 61.904762
“Past history of receiving formal treatment for anxiety or depression, n (%) 26 (52) 6 (26)*¥”
Abstract understates both mindfulness effect sizes tenfold
MinorThe abstract lists mindfulness effect sizes of 0.06 for MMP and 0.09 for MBCT, but the results list 0.6 and 0.9.
“p=.002, d=.07; p=.001, d=.08; p=.005, d=.06, respectively) and MBCT (p<.001, d=.06; p=.008, d=.04; p<.001, d=.09, respectively)”
“Mean FMI (SD) scores changed significantly from T1 to T2 for MBCT participants from 39.55 (7.16) to 46.39 (6.26) (p<.001, d=0.9) and for MMP participants, from 33.30 (8.53) to 39.43 (7.59) (p=.005; d=0.6).”

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 by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-11.
Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-11.
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.
