Zeroing In on Mindfulness Facets: Similarities, Validity, and Dimensionality across Three Independent Measures

Open access

Abstract

The field of mindfulness has seen a proliferation of psychometric measures, characterised by differences in operationalisation and conceptualisation. To illuminate the scope of, and offer insights into, the diversity apparent in the burgeoning literature, two distinct samples were used to examine the similarities, validity, and dimensionality of mindfulness facets and subscales across three independent measures: the Five Facet Mindfulness Questionnaire (FFMQ), Philadelphia Mindfulness Scale (PHLMS), and Toronto Mindfulness Scale (TMS). Results revealed problematic associations of FFMQ Observe with the other FFMQ facets and supported a four-factor structure (omitting this facet), while disputing the originally envisaged five-factor model; thus, solidifying a pattern in the literature. Results also confirmed the bidimensional nature of the PHLMS and TMS subscales, respectively. A joint Confirmatory Factor Analysis showed that PHLMS Acceptance could be assimilated within the FFMQ's four-factor model (as a distinct factor). The study offers a way of understanding interrelationships between the available mindfulness scales, so as to help practitioners and researchers make a more informed choice when conceptualising and operationalising mindfulness.

  • Other research supports a four-factor solution for the FFMQ due to poor internal consistency and model fit in confirmatory factor analyses.

    “However, other research supports a four-factor solution due to poor internal consistency and model fit in confirmatory factor analyses (CFA; e.g. Siegling & Petrides, 2016).”

    From Psychometric properties of acceptance measures: A systematic review (2019) · cites this paper as Siegling & Petrides, 2016

    The Results section, “Confirmatory Factor Analysis of FFMQ Hierarchical Models” (page not provided), reports that the five-factor FFMQ model fit poorly relative to a four-factor model omitting Observe. This supports the CFA model-fit rationale, but the passages do not identify poor internal consistency as a reason for preferring four factors. (LLM, conf=0.88)

  • The FFMQ non-judging subscale had strong positive correlations with the PHLMS acceptance scale in multiple studies (r=.58 and .72).

    “The non-judging subscale had strong positive correlations with the PHLMS acceptance scale in multiple studies ( r= .58 and .72, Siegling & Petrides, 2016; r= .58 and .72, Andrei et al., 2016).”

  • Three studies evaluated the PHLMS, and methodological quality varied from good to poor.

    “Three studies in this review evaluated the PHLMS, and methodological quality varied from good to poor (Andrei et al., 2016; Cardaciotto et al., 2008; Siegling & Petrides, 2016).”

    From Psychometric properties of acceptance measures: A systematic review (2019) · cites this paper as Siegling & Petrides, 2016

  • Siegling & Petrides (2016) and Andrei et al. (2016) demonstrated strong correlations between the PHLMS acceptance subscale and the FFMQ acceptance without judgement subscale (r=.58 and r=.58-.72 respectively).

    “Siegling & Petrides (2016) and Andrei et al. (2016) demonstrated strong correlations between the acceptance subscale and the AWJ subscale of the FFMQ ( r= .58 and r= .58-.72 respectively).”

  • The 'observe' facet currently negatively affects the validity of the FFMQ measure.

    “Dropping this facet may therefore be advisable, as it currently negatively affects the validity of the measure (Siegling and Petrides 2016).”

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.

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.
