“…Morales-Manrique et al compared DUQOL and IDUQOL to examine concurrent consistency and reported a direct and significant correlation [10]. The findings are also consistent with Roajs's et al results, so that the correlation between the Health-Related Quality of Life for Drug Abusers (HRQOLDA) and WHOQOL-BREF was equal to 0.72 and the correlation between HRQOLDA and DUQOl was equal to 0.61 [22].…”

Introduction: Drug dependence and the resultant problems notably decrease the quality of life (QOL). Measuring the QOL in persons who use drugs (PWUD s) and planning to improve it can be helpful for rehabilitation programs. Given the absence of a standard tool to measure the quality of life of PWUD, the present study is an attempt to validate psychometric and cultural characteristics of non-injection drug users' QOL scale. Method: The study was carried out as a validation and methodological work. The study population consisted of 273 PWUDs in Kermanshah-based drug clinics including outgoing and hospitalized patients. The participants were selected through convenient-quota sampling. After securing the required permission from the copyright owner of the tool, it was forward/backward translated. Face validity and content validity were determined quantitatively and qualitatively. To examine construct validity of the tool, explorative factor analysis and confirmatory factor analysis were used. Internal consistency was measured using Cronbach's alpha and statistical analyses were performed using SPSS (v.25) and LISREL (v.8). Results: Explorative factor analysis (EFA) and confirmatory factor analysis (CFA) results supported the tool with one factor and 22 items. The R2 index in the model was equal to 0.99, which means that 99% of the variation of dependent variable (total score of QOL) is attributed to independent variable (22 statements). In other words, 99% of the variation of dependent variable is due to the independent variables in the model. The main indices of the model based on CFA all were higher than 0.9, which indicates goodness of fit of the model (χ2/DF = 2.18, CFI, NFI, TLI = 0.93 GF = 0.84, REMSEA = 0.066, R2 = 0.99). The correlative coefficient was significant (p < 0.05). The reliability of the tool based on internal consistency (Cronbach's alpha) for the subscales ranged from 0.84 to 0.85 and equal to 0.84 for the whole tool. Conclusion: The Farsi version of non-injection drug users' QOL scale had acceptable indices and it was applicable to assess QOL in the target population. The tool can be used in different fields of drug addiction.

“…Quality of life has been described as a signi cant clinical and research outcome in the eld of chronic disease management, including substance use disorders [3,4]. Available data shows that substance abusers generally report lower QoL compared to general population and those with other serious psychiatric disorders [5,6].…”

Background Earlier literature has documented age related decline in executive functions (EF) in normal aging adults, yet it is unclear whether age related EF decline is linked with quality of life (QoL) possibly mediating the link between age and QoL. Therefore, the study hypothesized that selective EF components would mediate the association between age and QoL domains in young substance abuser men and family history of substance use would moderate these mediated associations. Method A sample of 212 young substance abuser men (105 positive family history and 107 negative family history of substance use) performed on performance measures assessing selective EF components—inhibition and cognitive flexibility. Also, they reported their QoL on self-report measure of WHOQOL. Results Mean scores of the sample on all QoL domains were lower than expected by chance. Also, the participants with positive family history of substance use compared to those with negative family history scored significantly lower on all QoL domains except physical QoL. Mediation analyses revealed that of two EF components, only inhibition mediated the negative association of age with psychological, social, and environmental QoL. Furthermore, family history of substance use moderated all the significant mediations with stronger indirect negative associations in participants having a family history of substance use compared to those with no such history. Conclusion It is concluded that inhibitory control, which is vulnerable to aging, substance use, and family history of substance use, is an important factor related to QoL in young substance abuser men.

“…Some authors advocate the use of instruments specifically designed for the target population (Rojas, Lozano, Foresti, Zolfaghari, & Zubaran, 2015). Yet, even though this would enable comparisons between the various treatments, it would prevent comparisons between the results with those obtained among the reference population.…”

Título: Calidad de vida en pacientes tratados con metadona: el WHO-QOL-BREF, estudio psicométrico y resultados de aplicación. Resumen: Objetivo. De entre los muchos instrumentos propuestos para medir la calidad de vida de los pacientes con adicción a opiáceos tratados con metadona el WHOQOL-BREF, propuesto por la World Health Organization, es el que más se utiliza en la actualidad. Este trabajo pretende estudiar la fiabilidad y la validez de constructo de la prueba, aplicada a una muestra amplia y representativa de pacientes, y comparar los resultados con los datos disponibles para población general en España. Se reclutó una muestra de 523 sujetos que se encontraban en tratamiento con metadona, en Madrid y Extremadura. Se efectuó un análisis factorial confirmatorio para probar la estructura teóricamente propuesta y, seguidamente, un análi-sis paralelo optimizado para conocer el número más adecuado de componentes de la prueba. Los resultados muestran que la prueba presenta sóli-dos valores de consistencia interna, tanto a nivel del ítem como de las escalas. La estructura tetradimensional teórica se confirma en la muestra con adecuados indicadores de ajuste, aunque también se obtienen serios argumentos para considerar su unidimensionalidad. Se estudió la relación estructural entre los cuatro dominios. El WHOQOL-BREF se muestra como una prueba fiable y válida para su uso en pacientes tratados con metadona, proporcionando una medida multidimensional de la calidad de vida percibida, que incluye factores sociales y ambientales ausentes en otros instrumentos, que son de enorme importancia en el tratamiento de los problemas adictivos. Palabras clave: Calidad de vida; WHOQOL-BREF; Tratamiento con metadona; Propiedades psicométricas; Análisis estructural; Adicción. Abstract:The most commonly instrument used to measure quality of life in patients with addictive behaviors is the WHOQOL-BREF, developed by the World Health Organization. No studies have been found to explore the psychometric properties in Spanish clinical samples. This paper aims to study their reliability as well as the construct validity in a representative sample of patients and comparing the results to the data available for the general population in Spain. A sample was recruited comprised of 523 subjects who were undergoing treatment with methadone in Madrid and Extremadura. A confirmatory factor analysis was completed to test the theoretically proposed structure and then an optimized-parallel analysis was done to establish the most adequate number of components. The result offers solid values for internal consistency both as concerns the items and the scales. The theoretical tetra-dimensional structure is confirmed in the sample although serious arguments are also found for considering its onedimensionality. The structural relationship between the four domains was studied. The WHOQOL-BREF proves to be a reliable and valid test for use on patients treated with methadone, providing a multi-dimensional measure of perceived quality of life that includes soci...
