Psychometric Properties of the Fagerström Test for Nicotine Dependence in a Sample of Mexican Smokers.

Introduction: The Fagerström Test for Nicotine Dependence (FTND) is a widely used six-item questionnaire, often used as a measure of physical dependence on nicotine, although evidence of its validity in Spanish-language studies is scarce.

Aim: The aim of this study was to assess the psychometric properties of FTND in Spanish speakers.

Method: We recruited 136 regular adult smokers to answer the FTND.

[Anxiety and depression in Mexican smokers, and their relationship with the severity of addiction].

Objective: To determine the relationship between the degree of addiction (DA) and pattern of tobacco consumption (PTC) with anxiety and depression in smokers who want to quit smoking.

Material And Methods: At admission to a smoking cessation program 495 smokers were surveyed to determine anxiety (IDARE Test), depression (Beck Inventory Test), DA (Fagerström Test) and PTC (pack-years).

Results: DA ≥ 6 points was associated with high anxiety levels RM=1.

Long-term changes in sleep and depressive symptoms of smokers in abstinence.

Few studies have evaluated the impact of smoking cessation on objective measures of sleep. The present study assessed the long-term effects of tobacco smoking abstinence on sleep and depression. A total of 15 chronic smokers with Hamilton Rating Scale for Depression (HAM-D) scores of less than 9 were evaluated.
