Consistency between definitions and measurement of mindfulness in eating and physical activity behavior: a scoping review.

Mindfulness (i.e., relating to one's internal and external awareness with non-evaluative attitudes) is increasingly applied as a determinant and strategy to change dietary and physical activity behaviours in the general adult population. However, current applications of mindfulness lack methodological standardisation, thereby limiting its comparison. The aim of this study was to examine currently applied conceptual definitions of mindfulness regarding their elements, their measurement, and the consistency between the defined elements and their measurement.Using scoping review methodology, we searched PubMed, PsycINFO, and Web of Science databases for peer-reviewed literature. Definitions were analyzed using an inductive content analysis approach. Consistency between defined elements and measurement was scored on an index. Across 57 records, less than half defined mindfulness as specific to a disposition, state, or action. One third described mindfulness as an attentional process without attitudinal elements. An additional 30% mentioned non-judgment as the singular attitudinal element underlying mindfulness. Empirical articles (n = 45) predominantly assessed dispositional mindfulness as a single score and frequently lacked measurement of defined attitudinal elements or measured elements that were not defined. To advance the systematic investigation of mindfulness, we present a conceptual model describing the measurement selection based on explicitly defined attentional and attitudinal mindfulness elements.

A Protection Motivation Theory Approach to Understanding How Fear of Falling Affects Physical Activity Determinants in Older Adults.

OBJECTIVES: This study applied an extended Protection Motivation Theory to investigate the relative importance of fear of falling (FoF) among motivational and intentional determinants of physical activity (PA) behavior. METHODS: Older U.S. adults (N = 667, 65+) were surveyed using online research panels and completed measures of self-efficacy and response efficacy (coping appraisal), perceived vulnerability and perceived severity (threat appraisal), FoF, autonomous motivation, intention, physical health, and past PA level. RESULTS: Our structural equation model showed that past PA level and health predicted intention via cognitive constructs. PA and health predicted FoF and motivation via threat and coping appraisal. FoF did not directly predict intention. DISCUSSION: Results from this sample provide support for the predictive effects of threat appraisal on fear. However, findings suggest that FoF may not be of great importance for the formation of PA intention compared with an established habit of being physically active and a subsequently fostered coping appraisal and motivation.

Examining socio-cognitive factors and beliefs about mindful eating in healthy adults with differing practice experience: a cross-sectional study.

BACKGROUND: Mindful eating (ME), defined as a "non-judgmental awareness of bodily and emotional sensations regarding food consumption", may be a promising strategy to promote healthy eating behaviors. However, little is known about the psychosocial factors and underlying beliefs that explain ME adoption. METHODS: Participants (N = 282; Mage = 43.2) responded to an online questionnaire based on the I-Change Model. Groups with different frequencies of prior engagement in ME, i.e., low (n = 82; LME), medium (n = 96), and high (n = 104), were compared via (M)ANOVAs on factors and individual beliefs regarding predisposing (i.e., habits, experience with mindfulness, emotional eating, facets of ME), pre-motivational (i.e., knowledge, behavioral cognizance, risk perception, cues to action), and motivational factors (i.e., attitudes, self-efficacy, social influence) as well as their intentions and action planning. Bivariate correlations and a forward-stepwise regression with ICM constructs were conducted to examine model fit. RESULTS: LME had a greater habit of mindless eating and significantly lower internal awareness, cognizance, cues, and less favorable attitudes, self-efficacy, engagement and support by their social environment, intention, and action plans about engaging in ME than the other two groups. Less habitual mindless eating, and greater experience, internal awareness, cognizance, susceptibility, support, and intention explained 54% of the variance in ME. DISCUSSION AND CONCLUSION: Results indicate that individuals need to be treated differently when promoting ME with respect to their psychosocial characteristics, rather than as a single group with homogenous baseline beliefs, abilities, support, and motivation. Future longitudinal research should examine which determinants are predictors of ME to better tailor program contents.

Development and Validation of the Four Facet Mindful Eating Scale (FFaMES).

OBJECTIVES: Previous mindful eating scales stress the attentional domains of eating-specific mindfulness, such as present-moment attention to homeostatic cues of hunger and satiety while discounting other important domains such as non-judgment and decentering. The purpose of the series of studies was to develop and evaluate a multifaceted mindful eating scale that assesses several domains of eating-specific mindfulness. METHODS: A multistep process was used to construct the Four Facet Mindful Eating Scale (FFaMES). Study 1 outlined the initial scale construction and the development of a novel item pool (N = 480). Study 2 examined the internal structure of the observed variables using exploratory analysis (N = 445) and confirmatory analysis in a separate sample (N = 445). Reliability and validity were assessed in Study 3 (N = 166). RESULTS: The final scale consists of 29 items with 4 factors: Non-Reactance, Non-Judgment, External Awareness, and Internal Awareness. The FFaMES demonstrated good internal consistency, retest reliability as well as preliminary convergent and divergent validity. CONCLUSIONS: Our findings provide reliability evidence and initial support for the construct validity of the FFaMES and the continued study of multiple facets of eating-specific mindfulness. Future research should continue to investigate the differential effects of various aspects of eating-specific mindfulness in the prevention and treatment of obesity and its comorbidities.
