Acute effect of Lavandula angustifolia essential oil on withdrawal syndrome symptoms in smokers
Description
The database corresponds to the research study entitled Acute effect of Lavandula angustifolia essential oil on withdrawal syndrome symptoms in smokers, which aimed to evaluate the acute effect of lavender essential oil on anxiety and craving in smokers during nicotine withdrawal. The hypothesis was that inhalation of the essential oil could reduce anxiety and the intense urge to smoke. The study included 60 participants divided into three groups of 20 individuals: GE; (Experimental Group), subjected to inhalation of Lavandula angustifolia essential oil; GCN (Negative Control Group), which received distilled water as a placebo; and GCP (Positive Control Group), treated with transdermal nicotine. Data were collected through pre-test and post-test assessments using validated questionnaires. The pre-test collected sociodemographic information, smoking history, nicotine dependence, anxiety, emotional state, and craving. In the post-test, these indicators were reassessed to identify changes following the interventions. In the GE and GCN groups, assessments were conducted after five minutes of inhalation, whereas in the GCP group, they were performed after four days of transdermal nicotine treatment. The degree of nicotine dependence (GRAUDEP) was measured using the FTND (Fagerström Test for Nicotine Dependence), which classifies dependence into five levels: very low (0–2 points), low (3–4), moderate (5), high (6–7), and very high (8–10). Anxiety was assessed using the State-Trait Anxiety Inventoryo (STAI), comprising two dimensions: IDATE-Traço (STAI-T; Trait Anxiety), which identifies an individual's tendency to respond with anxiety to threatening situations, and IDATE-Estado (STAI-S; State Anxiety), which assesses anxiety experienced at a specific moment. Each dimension contains 20 questions, with responses ranging from 1 to 4 points and total scores from 20 to 80, classified as low (20–40), moderate (41–60), and high (61–80) anxiety. IDATE-E was used to compare anxiety levels before and after the interventions. Craving, defined as an intense and urgent desire to smoke during withdrawal, was measured using the Questionnaire of Smoking Urges-Brief (QSU-B), consisting of ten questions rated on a seven-point Likert scale. The instrument assesses the desire and intention to smoke, anticipation of pleasure, and expectation of relief from withdrawal symptoms. Scores were classified as minimal craving (0–13 points), mild (14–26), moderate (27–42), and intense (43 or more). Its administration during the pre-test and post-test allowed the identification of changes in the urge to smoke. Emotional state was measured using the Escala Analógica do Humor (EAH; Visual Analog Mood Scale), consisting of 16 items assessed on visual scales ranging from 0 to 10. The instrument evaluates four factors: anxiety, sedation, cognitive impairment, and discomfort, reflecting subjective mood experiences during nicotine withdrawal.
