Experimentally Testing the Effect of Parent-Adolescent Conflict on HIV Risk, and Investigation of a Neurobiological Moderator of This Effect

Human immunodeficiency virus (HIV) is a condition in which immune cells become destroyed such that the body may become unable to fight off infections. Engaging in risk-taking behaviors (e.g., substance use) puts people at heightened risk for HIV infection, with mid-to-late adolescents at increasing risk (Leigh & Stall, 1993). Environmental and neurological reasons have been suggested for increased risk-taking among adolescents. First, family-level precursors such as parent-adolescent conflict have been significantly associated with and may pose risk for engaging in substance use and risk-taking (Duncan, Duncan, Biglan, & Ary, 1998). Thus, parent-adolescent conflict may be an important proximal influence on HIV risk behaviors (Lester et al., 2010; Rowe, Wang, Greenbaum, & Liddle, 2008). Yet, the temporal relation between parent-adolescent conflict and adolescent HIV risk-taking behaviors is still unknown. Second, at-risk adolescents may carry a neurobiological predisposition for engaging in trait-like expressions of disinhibited behavior and other risk-taking behaviors (Iacono, Malone, & McGue, 2008). When exposed to interpersonally stressful situations, their likelihood of engagement in HIV risk behaviors may increase. To investigate the role of parent-adolescent conflict in adolescent HIV risk-taking behaviors, 49 adolescents ages 14-17 and their parent were randomly assigned to complete a standardized discussion task to discuss a control topic or a conflict topic. Immediately after the discussion, adolescents completed a laboratory risk-taking measure. In a follow-up visit, eligible adolescents underwent electrophysiological (EEG) recording while completing a task designed to assess the presence of a neurobiological marker for behavioral disinhibition which I hypothesized would moderate the links between conflict and risk-taking. First, findings indicated that during the discussion task, adolescents in the conflict condition evidenced a significantly greater psychophysiological stress response relative to adolescents in the control condition. Second, a neurobiological marker of behavioral disinhibition moderated the relation between discussion condition and adolescent risk-taking, such that adolescents evidencing relatively high levels of a neurobiological marker related to sensation-seeking evidenced greater levels of risk-taking following the conflict condition, relative to the control condition. Lastly, I observed no significant relation between parent-adolescent conflict, the neurobiological marker of behavioral disinhibition and adolescent engagement in real-world risk-taking behavior.

Functional Neuroimaging of the Social Regulation of Emotion in Schizophrenia

Negative symptoms in schizophrenia are characterized by deficits in normative experiences and expression of emotion. Social anhedonia (diminished pleasure from social experiences) is one negative symptom that may impact patients’ motivation to engage in meaningful social relationships. Past research has begun to examine the mechanisms that underlie social anhedonia, but it is unclear how this lack of social interest may impact the typically positive effects of social buffering and social baseline theory whereby social support attenuates stress. The present pilot study examines how social affiliation through hand holding is related to subjective and neural threat processing, negative symptoms, and social functioning. Twenty-one participants (14 controls; 7 schizophrenia) developed social affiliation with a member of the research staff who served as the supportive partner during the threat task. Participants displayed greater subjective benefit to holding the hand of their partner during times of stress relative to being alone or with an anonymous experimenter, as indicated by self-reported increased positive valence and decreased arousal ratings. When examining the effects of group, hand holding, and their interaction on the neurological experience of threat during the fMRI task, the results were not significant. However, exploratory analyses identified preliminary data suggesting that controls experienced small relative increases in BOLD signal to threat when alone compared to being with the anonymous experimenter or their partner, whereas the schizophrenia group results indicated subtle relative decreases in BOLD signal to threat when alone compared to either of the hand holding conditions. Additionally, within the schizophrenia group, more positive valence in the partner condition was associated with less severe negative symptoms, better social functioning, and more social affiliation, whereas less arousal was correlated with more social affiliation. Our pilot study offers initial insights about the difficulties of building and using social affiliation and support through hand holding with individuals with schizophrenia during times of stress. Further research is necessary to clarify which types of support may be more or less beneficial to individuals with schizophrenia who may experience social anhedonia or paranoia with others that may challenge the otherwise positive effects of social buffering and maintaining a social baseline.

Gender, Behavioral Assessment of Negative Reinforcement Driven Risk Taking Propensity, and Cigarette Smoking

Cigarette smoking remains the leading preventable cause of death and disability in the United States and most often is initiated during adolescence. An emerging body of research suggests that a negative reinforcement model may explain factors that contribute to tobacco use during adolescence and that negative reinforcement processes may contribute to tobacco use to a greater extent among female adolescents than among male adolescents. However, the extant literature both on the relationship between negative reinforcement processes and adolescent tobacco use as well as on the relationship between gender, negative reinforcement processes, and adolescent tobacco use is limited by the sole reliance on self-report measures of negative reinforcement processes that may contribute to cigarette smoking. The current study aimed to further disentangle the relationships between negative reinforcement based risk taking, gender and tobacco use during older adolescence by utilizing a behavioral analogue measure of negative reinforcement based risk taking, the Maryland Resource for the Behavioral Utilization of the Reinforcement of Negative Stimuli (MRBURNS). Specifically, we examined the relationship between pumps on the MRBURNS, an indicator of risk taking, and smoking status as well as the interaction between MRBURNS pumps and gender for predicting smoking status. Participants included 103 older adolescents (n=51 smokers, 50.5% female, Age (M(SD) = 19.41(1.06)) who all attended one experimental session during which they completed the MRBURNS as well as self-report measures of tobacco use, nicotine dependence, alcohol use, depression, and anxiety. We utilized binary logistic regressions to examine the relationship between MRBURNS pumps and smoking status as well as the interactive effect of MRBURNS pumps and gender for predicting smoking status. Controlling for relevant covariates, pumps on the MRBURNS did not significantly predict smoking status and the interaction between pumps on the MRBURNS and gender also did not significantly predict smoking status. These findings highlight the importance of future research examining various task modifications to the MRBURNS as well as the need for replications of this study with larger, more diverse samples.

Cortisol Reactivity and Observed Parenting among Mothers of Children with and without ADHD

Parenting is a robust predictor of developmental outcomes among children with ADHD. Early parenting predicts the persistence and course of ADHD and comorbid problems above and beyond risk associated with shared genetic effects. Yet, on average, mothers of children with ADHD are less positive and more negative in their parent-child interactions compared to mothers of non-disordered children. Little is known about psychobiological markers which may be associated with individual variations in maternal parenting in families of children with ADHD. Neurobiological models of parenting suggest that maternal cortisol levels following a stressor may be positively associated with hostile and intrusive parenting; however, to date no studies have examined maternal cortisol reactivity and parenting in school-age, or clinical samples of, children. Mothers’ regulation of physiological stress responses may be particularly important for families of children with ADHD, as parenting a child with chronically challenging behaviors represents a persistent environmental stressor. The current study sought to extend the existing literature by providing an empirical examination of the relationship between maternal cortisol reactivity following two laboratory stressors and parenting among mothers of children with and without ADHD. It was hypothesized that child ADHD group would moderate the relationship between cortisol reactivity and self-reported and observed parenting. Greater total cortisol output and greater increase in cortisol during the TSST were associated with decreased positive parenting and increased negative and directive parenting, with the exception of parental involvement, which was associated with increased cortisol output during the TSST. Conversely, cortisol output during the PCI was associated with increased positive parenting, increased parental involvement, and decreased negative parenting. In contrast to the TSST, a greater decrease in cortisol during the PCI indicated more positive parenting and parental involvement. These associations were specific to mothers of children with ADHD, with the exception of maternal directiveness, which was specific to comparison mothers. Findings add to our understanding of physiological processes associated with maternal parenting and contribute to an integrative biological, psychological, and cognitive process model of parenting in families of children with ADHD.

Estilos pessoais dos terapeutas e estilos de vinculação

Neste estudo, procurou-se estudar a relação entre estilos pessoais e estilos de vinculação na relação terapêutica, procurando também, identificar outros aspetos que influenciam quer os estilos pessoais quer os estilos de vinculação duma amostra de psicoterapeutas. Esta amostra foi constituída por 40 licenciados em Psicologia Clínica, de ambos os sexos, com diferentes anos de experiência profissional. Os instrumentos utilizados foram o Questionário do Estilo pessoal (EPT) e a Escala de Vinculação de Adultos (EVA). Os resultados apontaram para uma associação entre a função instrutiva do EPT e o estilo de vinculação (terapeutas rígidos apresentam um estilo de vinculação ambivalente, enquanto que os terapeutas flexíveis apresentam um estilo de vinculação seguro), e entre algumas das funções do EPT com a orientação teórica, o grupo etário dos clientes e o género dos terapeutas. Conclui-se que a forma como os terapeutas estabelecem e regulam as suas sessões, está associada ao estilo de vinculação. ABSTRACT: ln this study, the priority goal was to identify which type of relationship exist between personnel styles and attachment styles in the therapeutic relationship; still point a characterization and a recognition of what aspects that can influence it, and then analyse it. The sample were constituted by 40 psychotherapists, they have a licenciature degree in clinical psychology, and the years of professional experience or the duration that they have the degree don't matter. The questionnaire EPT-C and the Adult attachment Scale-R (AAS-R). The results point to the association between the instructive function and attachment styles, as to the EPT-C functions with theoric orientation, age groups of clients, and therapists genres. The therapists that are rigids show a ambivalent style; but therapists flexible shows a secure style of attachment. lndeed the way as therapists stablish and regulate their sessions, is associated to the attachment style.

La posición socio económica en el campo de la actividad física y su relación con la imagen corporal: Aproximación desde el enfoque determinantes/ determinación social de la salud

El presente trabajo analiza la definición de la categoría posición socioeconómica (PSE) y las variables con las cuales se representa en los productos académicos del campo de la actividad física, además de su relación con la categoría de imagen corporal. Para lograr el objetivo, se rastrean elementos que permiten dar cuenta si los documentos de investigación se abordan desde alguno de los dos contextos: determinantes (DDSS) o determinación social de la salud (DSS). Se inicia con un rastreo global por medio de los motores de búsqueda, las bases de datos y los repositorios institucionales. Posteriormente se parametriza la ruta, desde las categorías imagen corporal (IC) y PSE. Las investigaciones pretenden dar cuenta de la evaluación a 15 años del programa "Salud para Todos" de la ONU de 2001, en el marco de los Objetivos Del Milenio. Se revisaron resúmenes de los productos, descartando aquellos donde la categoría PSE o sus descriptores asociados tuvieran un papel secundario. Se limitó a Latinoamérica y España por su tradición histórica colonizadora; con el ánimo de conocer la postura de esta comunidad frente al proceso globalizado de la salud en el mundo. Al grupo final se le aplican criterios parametrizados a partir de la revisión teórica, para responder los interrogantes basados en las implicaciones que tiene la PSE en el pensamiento actual de la producción científica en el campo de la actividad física; y cómo las otras categorías de análisis se ven o no manifiestas. El índice de calidad científica CASPe, determina la pertinencia de los textos. En el aspecto teórico, se encuentra que la categoría PSE, a pesar de ser muy utilizada, tiene una conceptualización difusa. Por tal motivo, se propone una definición de PSE sustentada en el pensamiento sociológico. En el aspecto empírico, al rastrear las variables con que se reemplaza la PSE en las investigaciones, se encuentran grandes diferencias y el uso de múltiples y disímiles subcategorías.

Ideación suicida y desesperanza en pacientes con cáncer

El objetivo de la presente investigación fue identificar la relación entre ideación suicida y desesperanza en 160 pacientes con cáncer. La ideación suicida se midió a través de dos ítems de una entrevista semiestructurada, la escala de ideación suicida (ISS), el ítem 9 del inventario de depresión de Beck (BDI-IA). La desesperanza se midió con la escala de desesperanza de Beck (BHS). Los resultados obtenidos indicaron una relación significativa (p=.000) entre ideación suicida y desesperanza; una prevalencia de ideación suicida en los pacientes con cáncer entre 4.4% y 13.8% y de riesgo de suicidio entre 5.6% y 30.6%; y algún grado de desesperanza en 31.9 % de los participantes. De acuerdo con lo anterior, se confirma que existe relación entre la desesperanza y la ideación suicida en pacientes oncológicos adultos. Adicionalmente, que estas variables están presentes en los pacientes y que ameritan atención en la intervención interdisciplinaria.

Resiliencia y desempeño organizacional

El cambio hoy se reconoce como el principal reto que enfrentan las empresas. Desde diversas ciencias como la biología, la psicología y la dirección se vienen estudiando las diferentes variables que tienen relación con los procesos de ajuste y adaptación que los individuos y las organizaciones desarrollan cuando disrupciones de diverso tipo se materializan en el entorno. En las últimas décadas se ha contemplado el estudio de la resiliencia como una característica que pueden desarrollar las organizaciones. Por ello, es un tema de estudio interesante, tanto desde los individuos como desde las organizaciones. Se revisan en este artículo los conceptos de resiliencia, resiliencia individual y organizacional, así como las relaciones que surgen entre dichos conceptos para explicar el desempeño organizacional.

Un protocolo de análisis contingencial : aproximación a la validez de contenido

El análisis contingencial es una alternativa novedosa ante los modelos de evaluación psicológica desarrollados previamente (psicopatológico, psicodinámico, de la terapia sistémica familiar, humanista y cognitivo-conductual), que pretende definir los problemas de los consultantes con base en las relaciones entre su comportamiento, la conducta de otros y las prácticas sociales en la que se circunscriben ambos. Con el objetivo de validar un protocolo de evaluación fundamentado en el análisis contingencial, tres psicólogos clínicos con experiencia, analizaron cada una de las categorías propuestas: datos iniciales, identificación de las relaciones microcontingenciales, definición de las relaciones macrocontingenciales, génesis del problema, análisis de soluciones y procedimientos de intervención; con base en los criterios de claridad (grado en el que el ítem es presentado de forma precisa y clara, que permite su fácil compresión) y pertinencia (correspondencia entre el contenido del ítem y la dimensión para la cual será usado). Los resultados encontrados indican que cada una de las categorías del protocolo permiten evaluar adecuadamente las problemáticas de los usuarios debido a que todas fueran consideradas como pertinentes, no obstante, se requiere modificar algunos aspectos ya que no cuentan con la claridad suficiente para ser comprensibles, probablemente por el uso de un lenguaje demasiado técnico, que conllevaría a errores en el proceso de evaluación.

Aproximaciones a mindfulness en la psicología contemporánea
