Dependence on hypnotics: a comparative study between chronic users of benzodiazepines and Z-drugs.

Objective: To evaluate dependence among chronic benzodiazepine and Z-drug users in Brazil.

Methods: Chronic users of benzodiazepines (n=94), Z-drugs (n=74), or both (n=11) were recruited from the community, underwent a psychiatric evaluation and completed self-report instruments on hypnotic dependence, insomnia, anxiety, and depression. Users of benzodiazepines and Z-drugs were compared using t-tests, and logistic regression models were employed to explore significant predictors of a dependence diagnosis.

Methods: One hundred and seventy-nine chronic hypnotic users (benzodiazepines and Z-drugs) were recruited, attended a psychiatric evaluation, and answered the BENDEP-SRQ-PV. Factor structure, reliability, and influence of covariates (dependence diagnosis and type of drug consumed) were assessed in a structural equation modelling environment.

Mindfulness-based interventions for the treatment of smoking: a systematic literature review.

Objectives: Smoking is a chronic process in which craving and negative affect are considered the main barriers to maintaining abstinence in patients who have gone through treatment. Mindfulness-based interventions have presented encouraging preliminary results in follow-up lasting up to 6 months. The aim of this study was to perform a systematic literature review on the effects of mindfulness-based interventions for the treatment of smoking.
