title: Validation of Five Facets Mindfulness Questionnaire – Short Form, in Spanish, general Health Care Services patients sample: Prediction of depression through Mindfulness scale.

description: The validation of Five Facets Mindfulness
Questionnaire (FFMQ)
- short version was performed in a general population of a city in a region of
Galicia (Spain), the sample was composed of randomly selected Spanish Health
Care patients (N = 845). The results on the goodness of fit of the
non-hierarchical, five-dimensional factorial model met the criteria for good
and acceptable model adjustment (after eliminating item 18 and despite the
correlations detected among the errors included in the model), explaining a
55.5%.of the variance. As the second objective has been analysed the
association between the scores obtained in the different facets of the FFMQ-SF
and the risk of suffering an episode of depression. (The Odd Ratio, the
Hosmer-Lemeshow test and the ROC curve were calculated.) Participants who were
currently suffering from an episode of depression were more likely to have low
scores in "describing" facet of Mindfulness (adjusted OR = 1.58, 95%
CI = 1.04-2.40, linear trend: χ2 = 3.74, df = 1, p = 0.053) as well as low
scores on "acting with awareness" (adjusted OR = 2.19, 95% CI =
1.461-3.30, linear trend: χ2 = 9.52, df = 1; = 0.002) and  "non judging" (adjusted OR = 2.05,
95% CI = 1.36-3.09, linear trend: χ2 = 143.21, df = 1; p &lt;0.001). Participants
with a previous episode of depression were more likely to have low scores on
the subscale "acting with awareness" (adjusted OR = 2.37, 95% CI =
1.43-3.93, linear trend: χ2 = 9.62, df = 1, p = 0.002) and "non-reactivity"
(adjusted OR = 2.14, 95% CI = 1.28-3.56, linear trend: χ2 = 8.30 ; df = 1; p =
0.004. Questionnaire
FFMQ-SF is an adequate questionnaire for the evaluation of mindfulness in
non-clinical multi- occupational population.

description: To validate the FFMQ-SF questionnaire in the general,
non-clinical, multi- occupational population, the 5-dimensional model described
previously was proposed [46]. We calculated means (standard deviations),
medians (interquartile intervals) and frequencies (percentages) for
sociodemographic data. The asymmetry, kurtosis and Mardia coefficients  [58] have been analyzed to evaluate the distribution of the items. We use
polymorphic matrices to estimate a more real correlation between the
theoretical continuous latent variables of the ordinal items observed, and we
estimate the characteristics of the matrices by the determinant of the
correlation matrix, the KMO index and the Bartlett sphericity test [59]. 

The determinant of the correlation matrix shows the
extent to which the variables are related and is zero when they are linearly
dependent. The KMO index of sampling adequacy predicts whether the data is
likely to have a good factor (KMO must be ≥0.70 to continue factor analysis). 

We use the goodness-of-fit index (GFI) and the
adjusted goodness-of-fit index (AGFI), which refer to the explained variance of
the model, and values&gt; 0.90 are acceptable [54]; also the standardized mean
square residual (RMSR), which is the standardized difference between the
observed and predicted covariance, and the square root of the mean squared
error (RMSEA), which indicate good adjustment values ​​when they score &lt;0.08
[54]; the standardized adjustment index (NFI) that measures the proportional
reduction in the adjustment function when going from null to the proposed
model, and the comparative adjustment index (CFI), in both is considered a good
fit of the model when they are&gt; 0.90 [60]. 

To analyze the relationship between the scores
obtained in the different facets of the FFMQ-SF and the suffering or not, a
current or past episode of depression, the Odd Ratio, the Hosmer-Lemeshow test
and the ROC curve were calculated.

 The data from
the questionnaires were analyzed statistically with the statistical package
SPSS 20 and AMOS v20. The cases that presented data misings were eliminated.

description: The sample was recruited from November 2012 to March
2015. All randomly selected subjects were contacted by postal mail first and
then by telephone in order to explain the study and summon them to the health
center. In case of agreeing to participate, they were assigned an appointment
in which a trained research assistant explained the study, obtained the
consent, solved doubts and collected the data.
