Facultad de Psicología

La Facultad de Psicología, su creación data del 2008, inició su vida institucional con la oferta de dos carreras: Psicología y Psicología Educativa. Han sentado sus bases en la pertinencia, respondiendo a la demanda social y laboral existente a nivel nacional y local. La carrera de Psicología responde al estudio del comportamiento y los procesos mentales de los sujetos, permite la comprensión de las conductas del ser humano a través de sus distintas aplicaciones y contribuye a la mejora de su bienestar. También debe predecir y controlar dichos procesos, con el propósito de promover el bienestar, la salud mental y el desarrollo humano. Si bien existen una variedad de enfoques y perspectivas teóricas, así como metodologías de investigación, podemos destacar el Conductismo, la Psicología Cognitiva, la Psicología Humanística, la Neuropsicología, entre otras. Actualmente, la Facultad de Psicología cuenta con una sola carrera vigente, que es la Licenciatura en Psicología, que se ubica dentro del campo de la salud.

Reliability and validity of the mental health continuum (MHC-SF) in the ecuadorian contexts
(2017) Peña Contreras, Eva Karina; Lima Castro, Sandra Eugenia; Bueno Pacheco, Gladys Alexandra; Aguilar Sizer, Mónica Elisa; Lee m Keyes, Corey; Arias Medina, William Paúl
Abstract: Health Continuum (MHC-SF) of Keyes (2009) in the Ecuadorian context. The scale was applied to two samples, one of 100 people that worked as a pilot and another of 550 people resident in the city of Cuenca-Ecuador, who also were applied an adaptation of the PERMA Profile of Butler and Kern (2016) to verify the convergent and discriminant validity. It was observed that the application in this population presents adequate levels of adjustment and high internal consistency (α=.91) and an adequate general adjustment of the structure of three factors: psychological well-being, social welfare and emotional well-being proposed by the author whose main fit values are RMSEA= .045, CFI= .996, χ2(52)= 109.048 (p= .000), GFI= .997 y TLI= 0.993. The bifactor model presents good values as well: RMSEA= .042, CFI= .996, χ2(52) = 103.040 (p= .000), GFI= .997, TLI= 0.993. We conclude that the Spanish version of MHC-SF (Keyes, 2009) and the bifactor model are appropriate tools to measure mental health in the Ecuadorian context
El inventario de funcionamiento ejecutivo para niños (CHEXI): evidencia sicométrica en una muestra de escolares ecuatorianos
(2024) Tacuri Reino, René David; Arias Medina, William Paúl; Bernal Arellano, Walter Marcelo
The Childhood Executive Functioning Inventory (CHEXI) is a widely used test in educational settings to identify deficits in Executive Functions (EF). This study aimed to adapt and evaluate the Spanish version of CHEXI in a sample of participants from Ecuador (n = 467). The study measured understanding using slightly different versions of the instrument, one initially administered to 373 participants and another with three item changes used to assess 144 new participants. Cronbach’s alpha (α) and McDonald’s omega (ω) were used to assess internal consistency. Absolute (χ²/df) and incremental fit indices (CFI, TLI, SRMR, RMSEA) evaluated construct validity. The two-factor structure of CHEXI (Working Memory and Inhibition) was successfully replicated, demonstrating a good fit and high internal consistency. The Spanish version, with the two first-order correlated factors and modifications in items 10, and 22, was deemed suitable for assessing EF in children aged 8 to 12. We found that modifying the statements improved the instrument’s psychometric properties for Ecuador.
Approach to a wellbeing model in ecuadorian adults
(2019) Aguilar Sizer, Mónica Elisa; Peña Contreras, Eva Karina; Arias Medina, William Paúl; Bueno Pacheco, Alexandra Elizabeth; Lima Castro, Sandra Eugenia
The aim of this study was to propose and evaluate a structural model that explains well-being as a synonym of positive mental health in Ecuadorians, taking into consideration a group of associated psychosocial variables evaluated through questionnaires. The sample included 1064 adults, inhabitants of Cuenca-Ecuador. The results were analysed with the software SPSS 20.0 and AMOS 23.0, using the generalized least squares method. Partial models were tested, the most satisfactory structural adjustment model obtained the following results; GFI=.91; AGFI=.90; RMR=.205; RMSEA=.041; CFI=.90. Three factors are included in the structure (Purpose, Positive Relationships and Growth), as well as the social well-being dimension. Self-assessment of health, self-efficacy and gratitude are important predictors of mental health while the increase of negative emotions showed a negative effect.
Factor structure, measurement invariance and psychometric properties of the Quality of Life Scale WHOQOL-BREF in the ecuadorian context
(2021) Aguilar Sizer, Mónica Elisa; Arias Medina, William Paúl; Lima Castro, Sandra Eugenia; Bueno Pacheco, Gladys Alexandra; Peña Contreras, Eva Karina; Cabrera Vélez, María Marcela
Background: The short version of the World Health Organization Quality of Life questionnaire (WHOQOL-BREF) is a popular instrument used to assess quality of life. The objective of this study was to evaluate the following psychometric properties: structural validity, convergent validity, internal consistency, and measurement invariance across sex of the WHOQOL-BREF in a sample of Ecuadorian adults. Methods: We used a sample of undergraduates (n = 987) to assess the WHOQOL-BREF original four-factor structure, a model with correlated factors, a hierarchical model, and two models resulting from the exploratory factor analysis and exploratory graph analysis. All the models were evaluated using confirmatory factor analysis. Results: The results of the exploratory factor analysis and exploratory graph analysis suggest that the items are organized into four factors, although differently from the original version and the orthogonality assumption is not maintained. The confirmatory factor analysis shows that the original WHOQOL-BREF structure with correlated factors presents adequate psychometric properties. However, we propose a four-factor structure that has the best psychometric properties and adequate internal consistency. The results of the measurement invariance show that strict and strong invariance is achieved between men and women. Convergent validity analysis reveals moderate correlations with self-esteem, resilience, and social support. Conclusions: Despite the original version of the WHOQOL-BREF with correlated factors has acceptable psychometric properties in the Ecuadorian context, we propose a version with a different organization of its items, which is consistent with the findings of other investigations.
Bienestar subjetivo y formación de cuidadores de adultos mayores
(2017) Peña Contreras, Eva Karina; Bueno Pacheco, Alexandra Elizabeth; Lima Castro, Sandra Eugenia; Cabrera Vélez, María Marcela; Aguilar Sizer, Mónica Elisa; Arias Medina, William Paúl
The proportion of senior citizens grows in the whole world and will continue to do so in the coming decades. For this reason, it is necessary to delineate and implement state plans to meet their social needs. These include the founding and maintenance of specialized social services and training of appropriate care staff. In this sense, the purpose of the research has been to establish the levels of well-being and the parameters that constitute it according to the opinion of Ecuadorian senior citizens. Data were obtained by applying the General Self-efficacy, General Welfare and Social Welfare, Gratitude Questionnaire, and self-perception questions to a sample of 386 senior citizens who were contacted at social service centers or while waiting for a public service. The analysis shows that self-efficacy and gratitude are predictive of well-being and that those participating in social service centers have higher average values at all scales. The results demonstrate the need for older adults to participate in academic, social and recreational activities to stren- gthen their psychological resources, with emphasis on self-efficacy and gratitude. In the training of caregivers, it should be emphasized that the care of the older adult transcends medical and nursing issues and that his subjective state of well-being is as important as material quality of life.
Propiedades psicométricas de las escalas de Actitudes Emprendedoras para Estudiantes y de Inteligencia Emocional de Wong y Law en una muestra de universitarios ecuatorianos.
(2023) Ortiz Ochoa, William Alfredo; Arias Medina, William Paúl; Tacuri Reino, René David; Domínguez Gómez, Marcela Anais
Emotional intelligence directly influences individual ́s personal development and could influence entrepreneurship skills as well. The objectives of this study were to assess the construct validity, internal consistency, and metric invariance of the Spanish version of the Wong and Law Emotional Intelligence Scale (WLEIS-S), and the Entrepreneurial Attitudes Scale for Students (EASS) and correlate the levels of emotional intelligence and entrepreneurship in a sample of university students (n=558). The validity, reliability, and invariance analysis reveal adequate goodness of fit, internal consistency and equivalence. In addition, statistically significant correlations were found between all dimensions of the scales. The Entrepreneurship and Emotional Intelligence Scales have adequate psychometric properties. In professional training, emotional intelligence acts as a decision-making ability and entrepreneurial capacity as a factor for future development
Psychometric properties of the resilience brief scale (BRS) in the ecuadorian
(2020) Bueno Pacheco, Gladys Alexandra; Peña Contreras, Eva Karina; Lima Castro, Sandra Eugenia; Arias Medina, William Paúl; Cabrera Vélez, María Marcela; Aguilar Sizer, Mónica Elisa
The aim of the present study was to evaluate the psychometric properties of the Brief Resilience Scale (BRS). The sample consisted of 657 Ecuadorian adults. We evaluated internal and construct validity, internal consistency, concurrent validity, and measurement invariance was tested across sex categories. The results show that the structure of two first order correlated factors presents adequate psychometric properties. Concurrent validity analysis shows that resilience correlates significantly with self esteem, social support and quality of life dimensions. Finally, psychometric equivalence is evidenced between the models of configural, metric, scalar and residual invariance. The BRS scale is a reliable and valid instrument for research and clinical practice purposes in the Ecuadorian context.
Factor structure, invariance and psychometric properties of the rosenberg self-esteem scale in the ecuadorian context
(2020) Bueno Pacheco, Alexandra; Lima Castro, Sandra Eugenia; Arias Medina, William Paúl; Peña Contreras, Eva Karina; Aguilar Sizer, Mónica Elisa; Cabrera Vélez, María Marcela
The aim of the present study was to evaluate the psychometric properties of the Rosenberg Self-Esteem Scale (RSE, Rosenberg, 1965) in the Ecuadorian context. The original version was evaluated along with alternative models proposed by other research in a sample of 535 adults in the city of Cuenca, Ecuador. The results of the confirmatory factor analysis show that the bifactor model has good internal consistency and adequate goodness of fit. Criterion validity was evaluated by correlating the dimensions of positive self-esteem and negative self-esteem with the subscales of the psychological domain of Quality of Life WHOQOL-BREF, Social Support of DUKE and Engagement to Life. Self-esteem measured by the RSE is essentially unidimensional and is invariant between the sex categories.
What money can-t buy: educational aspirations and international migration in Ecuador
(2020) Arias Medina, William Paúl; Rivera Ullauri, María José
This article studies how educational aspirations of children are shaped in Biblián, Ecuador, a traditional sending country. Data sources were a multi-level survey and semi-structured interviews that were analysed using logistic regression and thematic analysis, respectively. Several theoretical relationships are confirmed: the household socioeconomic status, caregiver-s educational aspirations and age are the most important variables that predict the educational aspirations of children. Child migratory dreams and the absence of the father or the mother only predict the educational aspiration of getting a high school degree, but do not predict the aspiration of a graduate degree. Thematic analysis suggests that, besides seeing education as a means to have higher incomes, mothers perceive it as a sign of social status and assign it an intrinsic value.
