Dispositional mindfulness, anticipation and abstinence symptoms related to hypnotic dependence among insomniac women who seek treatment: A cross-sectional study.

Introduction: Dispositional mindfulness can be described as the mental ability to pay attention to the present moment, non-judgmentally. There is evidence of inverse relation between dispositional mindfulness and insomnia and substance use, but as of yet, no studies evaluating the specific association between dispositional mindfulness and the components of hypnotic use disorder.

Objective: To evaluate the association between dispositional mindfulness and the components of dependence among female chronic hypnotic users.

Design And Method: Seventy-six women, chronic users of hypnotics, who resorted to Mindfulness-Based Relapse Prevention for the cessation of hypnotic use were included in the study. The Five Facet Mindfulness Questionnaire (FFMQ) evaluated the levels and facets of mindfulness, and the subscales of the Benzodiazepine Dependence Questionnaire (BENDEP) assessed dependence on hypnotics. We also evaluated sociodemographic variables and symptoms of insomnia and anxiety. The associations between the FFMQ facets and the BENDEP subscales were evaluated with binomial logistic regression, adjusted for income, schooling, anxiety, and insomnia.

Results: We observed associations between facets of the FFMQ and specific aspects of hypnotic dependence. The facet "observing" was inversely associated with the "concern about lack of availability of the hypnotic" [aOR = 0.87 95% CI (0.79-0.97)], and the facet "non-reacting to inner experience" with "noncompliance with the prescription recommendations" [aOR = 0.86 95% CI (0.75-0.99)]. The total score of the FFMQ was inversely associated to those two dependence subscales [aOR = 0.94 95% CI (0.89-0.99)]. "Observing" and "non-reactivity to inner experience" were also inversely associated with the "impairments related to the withdrawal symptoms" [aOR = 0.84 95% CI (0.73-0.97)] and [aOR = 0.78 95% CI (0.63-0.96)], respectively. The FFMQ was not associated with "awareness of problematic hypnotic use".

Conclusion: Dispositional mindfulness, specifically the facets "observing" and "non-reactivity to inner experience, were inversely associated with the components of hypnotic dependence related to the anticipation of having the substance, its expected effect, and the impairments caused by the abstinence. We discuss the implications of those results for the clinical practice and future investigations.
