Adaptation and validation of the Weight Efficacy Lifestyle Questionnaire (WEL) in a Chilean sample.

Self-efficacy is a cognitive-emotional factor that is consistently associated with behavioral change and, in particular, with changes in health behavior. Eating self-efficacy, understood as adopting and maintaining behaviors such as controlling one's weight and trusting in one's ability to control one's eating behavior, has been proposed for managing obesity. This study aimed to validate the Chilean version of the Weight Efficacy Lifestyle Questionnaire (WEL) in a sample of adults from the general population. Four hundred sixty-nine individuals (69.08% women, mean age = 38.02; SD = 10.31) participated in the study. An instrumental design was used geared toward developing tests and psychometric instruments, including adapting existing ones. Exploratory and confirmatory factor analyses were performed. The instrument version validated in Spain was applied in the study. The analysis obtained an instrument of 11 items with adequate psychometric properties allowing its use in clinical and research settings. It can help assess eating self-efficacy in the general population.

Etifoxine is non-inferior than clonazepam for reduction of anxiety symptoms in the treatment of anxiety disorders: a randomized, double blind, non-inferiority trial.

OBJECTIVE: To determine whether etifoxine, a non-benzodiazepine drug of the benzoxazine family, is non-inferior compared with clonazepam in the treatment of anxiety disorders. METHOD: A randomized controlled double blind trial with parallel groups was conducted. A total of 179 volunteer patients with a diagnosis of anxiety disorder (DSM-IV), between 18 and 64 years of age, participated in this study. The experimental group received 150 mg/day of etifoxine and the control 1 mg/day of clonazepam, both in three daily doses for 12 weeks. This treatment was completed by 87 participants, and 70 were available for follow-up at 24 weeks from start of treatment. The primary objective was a non-inferiority comparison between etifoxine and clonazepam in the decrease of anxiety symptoms (HAM-A) at 12 weeks of treatment. Secondary outcomes included the evaluation of medication side effects (UKU), anxiety symptoms at 24 weeks of treatment, and clinical improvement (CGI). Data analysis included multiple imputation of missing data. The effect of etifoxine on the HAM-A, UKU, and CGI was evaluated with the intention of treatment, and a sensitivity analysis of the results was conducted. Non-inferiority would be declared by a standardized mean difference (SMD) between clonazepam and etifoxine not superior to 0.31 in favour of clonazepam. RESULTS: Using imputed data, etifoxine shows non-inferiority to clonazepam on the reduction of anxiety symptoms at the 12-week (SMD = 0.407; 95% CI, 0.069, 0.746) and 24-week follow-ups (SMD = 0.484; 95% CI, 0.163, 0.806) and presented fewer side effects (SMD = 0.58; 95% CI, 0.287, 0.889). LOCF analysis shows that etifoxine is non-inferior to clonazepam on reduction of anxiety symptoms and adverse symptoms even when no change was assigned as result to participant whom withdrew. Non-inferiority could be declared for clinical improvement (SMD = 0.326; 95% CI, - 0.20, 0.858). CONCLUSION: Etifoxine was non-inferior to clonazepam on reduction of anxiety symptoms, adverse effects, and clinical improvement.

Plan nacional de salud mental. Reflexiones en torno a la implementación del modelo de psiquiatría comunitaria en Chile / Analysis of the new Chilean mental health care plan

During the sixties, the psychiatric care models evolved to a community care model, as a consequence of the asylum model failure. This new model assumes that psychosocial issues have a role, along with biological factors, in the development of mental diseases. In 2017 the National Mental health plan was created, based on this new model. It aimed to correct the flaws of the previous plan. We herein review this new plan, based on previous and international experiences. We also analyze the implementation of a community model of mental health care. The implementation of such a model without the support of the state and overlooking importance of mental health care, is extremely difficult.
