Estudio de correlación entre diferentes escalas que miden la dependencia al tabaquismo / Study of correlation between different scales that measure smoking dependence

Objetivo: Analizar la correlación entre los grados de dependencia al tabaquismo medidos mediante los test: Fagerström de dependencia a la nicotina (FTND), dependencia conductual Glover-Nilsson (GN-SBQ) y una medida de la dependencia autopercibida (DA). Diseño: Estudio observacional descriptivo transversal. Emplazamiento: Centro de salud urbano. Participantes: Varones y mujeres de 18 a 65 años, fumadores a diario, escogidos mediante muestreo consecutivo no aleatorizado. Intervenciones: Auto cumplimentación de diversos cuestionarios presentados a través de un dispositivo electrónico (del propio usuario o proporcionado por el centro de salud). Mediciones principales: Edad, sexo y dependencia a la nicotina evaluada mediante FTND, GN-SBQ y DA. Análisis estadístico con SPSS® v.15.0: estadística descriptiva, análisis de correlación de Pearson y análisis de conformidad. Resultados: Se incluyeron 214 individuos (54,7% mujeres) y una edad media de 52 años (rango: 27-65). Dependiendo del test utilizado, obtuvimos resultados dispares, en el nivel de dependencia alta/muy alta medido: FTND 17,3%; TG- SBQ 15,4% y DA 69,6%. La correlación de los 3 test fue de magnitud moderada (r≈0,5). Al evaluar la concordancia, comparando el FTND con la DA, en el 70,6% de los fumadores los niveles de dependencia no coincidían, sugiriendo FTND un grado de dependencia más leve que lo estimado mediante la DA. GN-SBQ vs. FTND, mostró conformidad (los niveles de dependencia eran equivalentes) en el 44,4%, mientras que en el 40,7% FTND infraestimó la dependencia respecto al GN-SBQ. Comparando DA vs. GN-SBQ, en el 64% GN-SBQ infraestimó y hubo conformidad en el 34,1%. Conclusiones: Los pacientes que consideran una DA alta/muy alta es 4 veces superior respecto a GN-SBQ y FTND; siendo FTND el más exigente categorizando a los pacientes con dependencia muy alta. Considerar únicamente FTND de 7 para financiar la deshabituación tabáquica puede excluir a pacientes subsidiarios recibir tratamiento.(AU)

Objective: To analyze the correlation between the degrees of smoking dependence, measured with the Fagerström Test Nicotine Dependence (FTND), Glover-Nilsson Smoking Behavioral Dependence (GN-SBQ) and a measure of self-perceived-dependence (SPD). Design: Cross-sectional descriptive observational study. Site: Urban primary health-care center. Participants: Men and women between 18 and 65 years old, daily smokers, selected by non-random consecutive sampling. Interventions: Self-administration of various questionnaires though an electronic device. Main measurements: Age, sex and nicotine dependence assessed by: FTND, GN-SBQ and SPD. Statistical analysis, with SPSS 15.0: descriptive statistics, Pearson correlation analysis and conformity analysis. Results: Two hundred fourteen smokers were included, 54.7% were women. Median age 52 years (range: 27-65). Depending on the test used, different results of the high/very high degree of dependence were found: FTND 17.3%, GN-SBQ 15.4% and SPD 69.6%. A moderate magnitude (r≈0.5) correlation between the 3 test was found. When assessing concordance, comparing the FTND with SPD, 70.6% of smokers didn’t coincide in the severity of dependence, reporting a milder degree of dependence with the FTND than with SPD. Comparing GN-SBQ versus FTND, showed conformity in 44.4% of patients while in 40.7%, the FTND underestimated the severity of dependence. Likewise, when comparing SPD with the GN-SBQ, in the 64% GN-SBQ underestimates, while in 34.1% smokers conformity was demonstrated. Conclusions: The number of patients who consider their SPD to be high/very high was four times higher compared to the GN-SBQ or the FNTD; the latter, being the most demanding, categorizing patients with very high dependence. Requiring a FTND score greater than 7 to prescribe drugs for smoking cessation may exclude subsidiary patients from receiving treatment.(AU)
