Este grupo de investigación tiene como marco de referencia el modelo biopsicosocial. Sus investigaciones se caracterizan por un trabajo riguroso y sistemático para la construcción de evidencia en los diferentes campos de la psicología, desde un marco ecológico que reconoce la interacción entre los diferentes niveles en los que el ser humano se inserta y la necesidad de utilizar métodos diversos para comprender los fenómenos del ser humano desde un enfoque holista e integrador.

Cognitive behavioral therapy reduces illness perceptions and anxiety symptoms in patients with unruptured intracranial aneurysm
(Churchill Livingstone, 2020-01-01) Lemos M.; Román-Calderón J.P.; Restrepo J.; Gómez-Hoyos J.F.; Jimenez C.M.; Lemos M.; Román-Calderón J.P.; Restrepo J.; Gómez-Hoyos J.F.; Jimenez C.M.; Universidad EAFIT. Departamento de Humanidades; Estudios en Psicología
The main purpose of this study was to assess the relation between cognitive behavioral therapy and possible changes in illness perceptions and anxiety in patients diagnosed with unruptured intracranial aneurysm. An observational study of an intervention with 67 patients with an unruptured intracranial aneurysm from two medical centers in a Colombian city (n = 35 on the intervention group) was carried out. To assess changes, measurements were taken at baseline and at one-year follow-up with the Beck Anxiety Inventory and the Illness Perception Questionnaire, brief version, taking into account the importance of perceptions in the process of adjusting to illness and acquiring healthy life habits. Hypotheses were tested by a structural model. The results obtained from this study showed that illness perceptions were related to anxiety levels at both time points; however, the relations were stronger before cognitive behavioral therapy (ßt0 = 0.61, p < 0.01; ßt1 = 0.37, p < 0.01). Cognitive behavioral therapy was found to be a moderator of changes in both illness perceptions and anxiety at the time of follow-up (ß = -0.31, p < 0.01; ß = -0.26, p < 0.01). The structural model suggests that cognitive behavioral therapy is associated with less anxiety (ß = -0.17, p < 0.05) and better illness perceptions (ß = -0.35, p < 0.01) in patients diagnosed with unruptured intracranial aneurysms. © 2020 Elsevier Ltd
Personality and anxiety are related to health-related quality of life in unruptured intracranial aneurysm patients selected for non-intervention: A cross sectional study
(Public Library of Science, 2020-03-12) Lemos, M.; Roman, J.; Lemos, M.; Roman, J.; Universidad EAFIT. Departamento de Humanidades; Estudios en Psicología
Background Personality traits and mental health problems have been previously reported in unruptured intracranial aneurysm (UIA) patients; however, few studies have clarified the relations between these variables and health-related quality of life (HRQoL). This study was designed to characterize the personality traits, HRQoL and mental health of patients with UIA and to evaluate whether personality has an influence on HRQoL and whether this is mediated by the patients’ emotional symptoms. Methods Sixty-three patients with UIAs (mean age 62.6 years, 83.9% women) answered questionnaires for depression, anxiety, HRQoL and personality traits between June 2016 and May 2019. Results Eight percent of the sample had depression, and 27.4% had anxiety. Participants showed high levels of responsibility, kindness and neuroticism and low levels of extraversion and openness. HRQoL scores were normal compared with the Colombian population. Structural equation analysis showed that patients’ HRQoL was negatively affected by anxiety levels and that the latter are associated with the patient’s personality, where neuroticism is directly associated with symptomatology and inversely associated with extraversion. Conclusions The results of this study showed the importance of personality and emotional symptoms in the HRQoL of UIA patients. These results are important for developing strategies for psychological counseling in patients with UIAs. © 2020 Lemos et al.

The Techniques for Overcoming Depression Questionnaire: Mokken Scale Analysis, Reliability, and Concurrent Validity in Depressed Cardiac Patients
(SPRINGER/PLENUM PUBLISHERS, 2017-02-01) Freedland, K.E.; Lemos, M.; Doyle, F.; Steinmeyer, B.C.; Csik, I.; Carney, R.M.; Freedland, K.E.; Lemos, M.; Doyle, F.; Steinmeyer, B.C.; Csik, I.; Carney, R.M.; Universidad EAFIT. Departamento de Humanidades; Estudios en Psicología
The Techniques for Overcoming Depression (TOD) questionnaire assesses the frequency with which patients being treated for depression use cognitive-behavioral techniques in daily life. This study examined its latent structure, reliability and concurrent validity in depressed cardiac patients. The TOD was administered at the initial and final treatment sessions in three trials of cognitive behavior therapy (CBT) (n = 260) for depression in cardiac patients. Mokken scaling was used to determine its dimensionality. The TOD is unidimensional in depressed cardiac patients, both at the initial evaluation (H = .46) and the end of treatment (H = .47). It is sensitive to change and the total score correlates with therapist ratings of the patient’s socialization to CBT (r = .40, p < .05), homework adherence (r = .36, p < .05), and use of cognitive-behavioral techniques (r = .51, p < .01). TOD scores were associated with post-treatment depression scores in two of the trials (p < .01 in both analyses). The TOD is a unidimensional, reliable, valid, and clinically informative measure of self-reported use of cognitive-behavioral techniques for overcoming depression in cardiac patients. Studies of the TOD in other depressed patient populations are needed. © 2016, Springer Science+Business Media New York.
