, 1983), for its use in Mexican samples. Using a random sample of students, internal consistency was analyzed and the factor structure of the Spanish version of the PSS was compared with the factor structure found in the English version. Internal consistency was adequate (α = .83) and confirmatory factor analysis corroborated the factor structure. Factor 1 explained 42.8% of the variance and Factor 2 accounted for 53.2%. The goodness-of-fit measures also revealed an adequate fit. The cultural adaptation of the PSS was also evaluated with satisfactory results. Keywords: PSS, psychometric properties, Spanish, Mexico, perceived stressEl estudio tiene como propósito valorar la adaptación cultural realizada a la versión española de la Escala de Estrés Percibido (Cohen, Kamarak y Mermelstein, 1983), para ser utilizada en muestras de México. Se analizó la consistencia interna y la estructura factorial de la versión en español del PSS y se comparó con la estructura factorial encontrada para la versión en inglés, utilizando una muestra aleatoria de estudiantes. Los resultados indican una adecuada consistencia interna (α = .83) y se confirma la estructura factorial al utilizarse análisis factorial confirmatorio; con el Factor 1 explicando un 42.8% de la varianza y el Factor 2, un 53.2%, así como estadísticos de ajuste aceptables en el AFC. Asimismo, se evaluó, con resultados satisfactorios, la adaptación cultural realizada para el PSS.
There are few studies on coping with fibromyalgia (FM). The aim of the present study was to assess the usefulness of a Spanish version of the Chronic Pain Coping Inventory-42 (CPCI-42) in patients with FM. A random sample (N=402) of patients with FM was obtained from the Fibromyalgia Association of Aragon, Spain. Patients were assessed with the CPCI-42, the Fibrofatigue Scale (FFS), the EuroQol-5D (EQ-5D), and the Hospital Anxiety and Depression Scale (HADS). The psychometric properties of the CPCI-42 were valid and factor analyses supported the eight-factor structure described in patients with chronic pain. Illness-focused coping strategies (i.e., guarding, resting, and asking for assistance) were strongly correlated with each other, positively correlated with disability and depression, and negatively correlated with quality of life, indicating construct validity. Seeking social support was weakly correlated with any other scale or outcome, confirming it belongs to a different group of coping strategies. The wellness-focused group of coping strategies was the most incoherent group. Task persistence correlated with illness-focused strategies and negative outcomes, indicating that it should be included in the illness-focused group. However, other wellness-focused strategies, including relaxation, exercise, and coping self-statements, were correlated with each other, negatively correlated with depression, and positively correlated with quality of life. Future research directions and clinical implications are discussed.
Abstract. Bruxism is a jaw muscle activity that involves physio-pathological, psycho-social, hereditary and genetic factors. The purpose of this study was to determine the associations between self-reported bruxism, anxiety, and neuroticism personality trait with the rs6313 polymorphism in the gene HTR2A. A sample of 171 subjects of both sexes (14-53 years of age) was included. The control group (group 1, n=60) exhibited no signs or symptoms of bruxism. The case group had signs and symptoms of bruxism (n=112) and was subdivided into group 2, bruxism during sleep (n=22); group 3, awake bruxism (n=44); and group 4 combined bruxism (n=46). As diagnostic tools, the Self-Reported Bruxism Questionnaire (SBQ), the Beck Anxiety Inventory (BAI) and the Eysenck Personality Questionnaire Revised-Abbreviated (EPQR-A) were used. HTR2A (rs6313) SNPs were determined by qPCR for all the participants. The packages SPSS, maxLik and EPI-INFO were used for data analysis. The combined bruxism group reported higher scores in bruxism symptoms, mean = 32.21; anxiety symptoms, mean = 14.80; and neuroticism, mean = 3.26. Combined bruxism was associated with a higher degree of neuroticism (OR=15.0; CI 1.52-148.32) and anxiety in grade 3-moderate (OR=3.56; CI 1.27-10.03), and grade 4-severe (OR=8.40; CI 1.45-48.61), as determined using EPISODE computer software. Genotypic homogeneity analysis revealed no significant differences in allele frequency (P=0.612) among the four groups. The population was in Hardy-Weinberg equilibrium (maxLik package). In conclusion, the three instruments confirm traits of bruxism, anxiety and neuroticism in individuals with bruxism. These data were ratified when the sample was divided by genotypic homo geneity. On the other hand, there was no significant difference between the groups in the SNPs rs6313 from the HTR2A gene.
OBJECTIVE The objective of this study has been to test the ability of variables of a psychological model to predict antiretroviral therapy medication adherence behavior.METHODS We have conducted a cross-sectional study among 172 persons living with HIV/AIDS (PLWHA), who completed four self-administered assessments: 1) the Psychological Variables and Adherence Behaviors Questionnaire, 2) the Stress-Related Situation Scale to assess the variable of Personality, 3) The Zung Depression Scale, and 4) the Duke-UNC Functional Social Support Questionnaire. Structural equation modeling was used to construct a model to predict medication adherence behaviors.RESULTS Out of all the participants, 141 (82%) have been considered 100% adherent to antiretroviral therapy. Structural equation modeling has confirmed the direct effect that personality (decision-making and tolerance of frustration) has on motives to behave, or act accordingly, which was in turn directly related to medication adherence behaviors. In addition, these behaviors have had a direct and significant effect on viral load, as well as an indirect effect on CD4 cell count. The final model demonstrates the congruence between theory and data (x 2/df. = 1.480, goodness of fit index = 0.97, adjusted goodness of fit index = 0.94, comparative fit index = 0.98, root mean square error of approximation = 0.05), accounting for 55.7% of the variance.CONCLUSIONS The results of this study support our theoretical model as a conceptual framework for the prediction of medication adherence behaviors in persons living with HIV/AIDS. Implications for designing, implementing, and evaluating intervention programs based on the model are to be discussed.
