Prueba Stroop computarizada de riesgo tabáquico para adolescentes
Calleja, Nazira;Hernández-Pozo, Maria Del Rocío;
Revista mexicana de análisis de la conducta , 2009,
Abstract: a stroop discriminative test was built to assess interference produced by words associated to tobacco use among teenagers. in the first phase of the study 473 junior high school students, men and women, wrote positive and negative words related to smoking or to tobacco, and neutral words not associated to the subject. fifteen of the most frequent positive, negative and associated words were selected to create pairs with neutral words equal in length and frequency of use. three versions of the computerized smoking risk stroop test were built based upon selected dyads, by varying the order of the blocks. in the second phase of the study, 164 junior high school students, men and women, were exposed to the discriminative task, in which they had to press the number identifying the color in which the word was written on the screen. order of the blocks did not affect interference indexes. negative interferences correlated significantly with associated neutral words interference, but not with positive interference. it is concluded that the stroop test for smoking risk assesses attentional bias related to smoking and to tobacco among adolescents, and that either order of block is equivalent for practical use.
VALIDACIóN DE UNA LISTA DE MIEDOS EN POBLACIóN MEXICANA
Hernández-Pozo, María del Rocío,Calleja, Nazira,Sánchez Velasco, Alejandra,Coronado álvarez, Osmaldo
Acta Colombiana de Psicología , 2009,
Abstract: Fear is an emotional response to negative challenge; as a dispositional event it affects the probability of behavior and it might have consequences for the physical and psychological health of the individual. Lang (1970) theoretical approach to the study of fear holds the notion that fear reactions belong to a triple system involving physiological arousal, subjective reactivity and behavioral avoidance, and that these components interact in a flexible manner (Rachman, 2004). The purpose of this study was to validate a Fear Checklist written in Spanish, with 31 terms related to topics potentially fear evoking. Participants were 605 people whose ages ranged from 14 to 60 years. Their task consisted of assigning a score from 0 to 5 to each term, according to the degree of fear associated with each word. An item analysis was carried out which resulted in the discharge of three items. The remaining 28 items were subjected to factor analysis and led to four factors with loadings above .44, thus explaining 68% of the total variance, with a reliability index of .967. Resulting fear factors were affective loss, becoming a victim of non-contingent events, vulnerability and death. Women got higher scores in all subscales, with the exception of death. The study concluded that the Fears' Checklist is an instrument easy to comprehend and to apply that could be potentially useful for exploring fears in the Spanish speaking population

Trabajolismo: Radiografía contingencial de una adicción
Hernández-Pozo, María del Rocío;
Revista mexicana de análisis de la conducta , 2010, DOI: 10.5514/rmac.v36.i3.08
Abstract: the contingency language developed by mechner (2008) is proposed for examining variables responsible for production and maintenance of addictive behavior for work. three associated terms are examined: workaholism, burnout and passion for work from specialized literature in the field of health and organization psychology. a diagram with symbolic elements is presented to facilitate visual detection of iterative relationships that maintain these tendencies at different stages, the first where the employee exhibits an intense rhythm of work in the absence of stimulus control that prevents detachment from work, even outside working hours. positive and negative consequences at different scenarios are depicted, as a result of this life style, to be followed by a major health crisis that leads to rehabilitation. as a conclusion the use of contingency diagrams is proposed for the interdisciplinary study of workaholic behavior that will aid in the prevention of this health problem.
CRITICAL REVIEW OF EMPIRICAL RESEARCH DEALING WITH THE RELATIONSHIP BETWEEN OPTIMISTIC TENDENCIES AND HIV RELATED BEHAVIORS
Santillán Torres Torija,Carolina; Hernández-Pozo,María del Rocío;

Abstract: many variables related to risk of hiv infection, progression of the disease and adherence to antiretroviral drug therapy have been studied from different approaches. this review incorporates a group of studies including optimism as a variable related to positive psychology and hiv/aids, to explain how it interacts with: sexual risk behaviors, disease progression and adherence to antiretroviral (arv) therapy. refereed academic journals published from 1994 to 2009, were accessed from the ebsco database. subject terms were related both to hiv and optimism. articles were arranged into three classifications: infection, disease progression and arv therapy adherence. the review included 32 articles carried out mainly in the usa. most articles showed significant relationships between optimism and risk behaviors, disease progression and arv adherence. this study concluded that more research in evaluation of optimism, and optimism related interventions should be made to disentangle the complex relationship it has with sex risk behaviors, disease progression and adherence to arv therapy. moderate optimism appears to be a predictor to health related sexual behaviors.
MECHNER'S NOTATION USED AS A COMPARATIVE TOOL OF DIABETES SELF-MANAGEMENT ENHANCEMENT INTERVENTIONS
Hernández-Pozo,María del Rocío; Hattori-Hara,Mónica;
Suma Psicológica , 2012,
Abstract: elder population is becoming proportionally a larger segment of the total population and among their health problems, diabetes mellitus (dm) is one of their main causes of death and disability. in dm, self-management is the basis for a better control, which is why public policy makers and healthcare providers should have available analytic tools that allow them to discriminate among the best self-care interventions in diabetes for older patients. even though there are several meta-analyses already that offer this kind of review, this article proposes the use of mechner's behavioral contingencies language to compare different approaches. three interventions were described with this notation and even though there were some limitations for this analysis due to the fact that some results were not comparable or not available in the original papers, this formal symbolic language demonstrated to be useful for making analytical comparisons visually accessible, providing a better understanding of the contingencies that are at play in the situation and giving the advantage of cutting across all natural languages.
Evaluación de la impulsividad en fumadores: una revisión sistemática
Cuevas Aguirre, Eduardo;Hernández-Pozo, María del Rocío;
Revista mexicana de análisis de la conducta , 2008,
Abstract: due to its complexity, the study of the concept of impulsivity has been of interest for economy, sociology, psychology and medicine. different measures are used to conduct research in impulsivity, these techniques are either self-reports or behavioral paradigms. studies dealing with impulsivity and tobacco consumption are relatively new and they could be useful to understand the relationship between this tendency and smoking. it is possible that impulsivity is a factor that prevent cessation of tobacco consumption and that this tendency contributes for relapses. the present systematic review has as its central goal to discuss in detail different forms used in the literature to assess impulsivity among smokers. based on the search on data bases such as pubmed, scopus, sciencedirect, springer and eric, 3025 articles were found related with impulsivity, from which 700 directly evaluated it. only 106 articles dealt with impulsivity related to smoking behavior and among them only 20 provided measures focused directly on impulsivity among smokers. the review concludes that the joint use of behavioral performance task plus self-reports for assessment of impulsivity, allows a better grasp in the comprehension and explanation of the target phenomena.
Indicadores conductuales de ansiedad escolar en bachilleres en función de sus calificaciones en un examen de matemáticas
MACíAS-MARTíNEZ,DANIEL; HERNáNDEZ-POZO,MARíA DEL ROCíO;
Universitas Psychologica , 2008,
Abstract: the study of mathematics has been and is still a source of frustration and anxiety for a large number of students. the purpose of this study was to inquire systematically upon levels of test anxiety through behavioral and physiological procedures before and after a math test, in 205 senior high school students. academic worries were assessed by means of a computerized task based on the emotional version of the stroop paradigm designed ex profeso to measure school anxiety (hernández-pozo, macías & torres, 2004). the stroop task was administered, along with recordings of blood pressure and pulse, before and after the first math test of the course. academic general scores were inverse to the behavioral anxiety level, however the best math scores were associated to middle levels of behavioral anxiety. contradictory findings between academic performance in math and global score, and the apparent lack of gender difference in anxiety measured through behavioral procedures suggests the need to review the generality of previous assertions relating academic performance inversely with levels of anxiety of high school students.
