Using a nationally representative sample (N = 870), the present study compared long‐distance romantic relationships to close‐proximity romantic relationships in terms of relationship quality, commitment, and stability. Individuals in long‐distance relationships generally reported higher levels of relationship quality on a number of relationship quality variables, as well as higher levels of dedication to their relationships and lower levels of feeling trapped (i.e., felt constraint), but were similar to individuals in close‐proximity relationships in terms of perceived and material constraints. Although individuals in long‐distance relationships perceived a lower likelihood of breaking up with their partner at the initial time point, they were as likely as the individuals in close‐proximity relationships to have broken up by the follow‐up assessment.  相似文献

The aim of this study was to determine if patients with Borderline Personality Disorder (BPD) present higher emotional response than healthy controls in a laboratory setting. Fifty participants (35 patients with BPD and 15 healthy controls) underwent a negative emotion induction procedure (presentation of standardized unpleasant images). Subjective emotional responses were assessed by means of self-reported questionnaires while biological reactivity during the procedure was measured through levels of salivary cortisol (sCORT) and alphaamylase (sAA). Patients with BPD exhibited significant lower cortisol levels and higher sAA levels compared to controls. Self-reported emotional reactivity did not give rise to differences between groups but participants with BPD did present higher levels of negative emotional intensity at baseline and during the entire procedure. The findings do not give support to the emotional hyperreactivity hypothesis in BPD. However, BPD patients presented heightened negative mood intensity at baseline, which should be considered a hallmark of the disorder. Further studies using more BPD-specific emotion inductions are needed to confirm the trends observed in this study.  相似文献

The aim of this paper is to validate the Internet Related Experiences Questionnaire (IREQ) with a sample of 525 participants from Compulsory Secondary Education, considering the possible addiction to the internet from both interpersonal and intrapersonal dimensions. Besides, associations between CERI scores and several variables such as sex, age as well as selfesteem were analyzed. Results show a good fit of the questionnaire through a Confirmatory Factor Analysis (CFA), where the interpersonal factor explains a higher percentage of the variance at the expense of the intrapersonal factor. Statistically significant differences between IREQ scores and age and a lineal positive association between self-esteem and possible interpersonal addiction to the internet were found. The possibility of these results to be affected by the social use of the Internet and the generalization in young people's lives is discussed. Moreover, the need of designing and implementing prevention programs for a healthy use of the internet is discussed.  相似文献

The Personality Diagnostic Questionnaire-4+ (PDQ-4+) is a self-report used for the assessment of personality disorder traits, however, its psychometric characteristics have yet to be tested in community samples of adolescents. The main goal was to analyze the psychometric properties of the PDQ-4+ scores in a large sample of non-clinical adolescents (N = 1,443; M = 15.9 years; SD = 1.2). The PDQ-4+ scores showed adequate psychometric properties. Reliability of the subscales, incorporating a Likert-type 5-point response format, ranged from .62 to .85. The study of the internal structure at item level revealed that the PDQ-4+ subscales were essentially one-dimensional. Analysis of the internal structure at the subscale level by means of exploratory factor analysis and exploratory structural equation modeling yielded a possible three-dimensional solution. The PDQ-4+ subscales correlated moderately with emotional and behavioural variables measured by the Strengths and Difficulties Questionnaire. The results have clear implications for the understanding of maladaptive personality traits in adolescents.  相似文献

Attention Deficit Hyperactivity Disorder (ADHD) is one of the disorders causing the greatest impact, conditioning academic learning, quality of concentration, and capacity for self-regulation and control. The Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV-TR) establishes the most commonly accepted criteria for diagnosis (Inattentive: ADHD-I, Hyperactive/impulsive: ADHD-HI, and Combined: ADHD-C), but currently, diverse studies disagree about whether to address it as a continuum with different degrees of intensity (subtype structure) or as specific disorders (counterposed profiles). Prior research has tested the hypothesis of differential categories with performance measures and cortical activation. The goal proposed herein is to confirm these results, incorporating a new measure, near-infrared hemoencefalography (nir-HEG), in order to control cortical activation through levels of blood oxygenation. For this purpose, we used a sample of 205 children between 8 and 13 years (105 control group, 28 with ADHD-I, 35 with ADHD-HI, and 37 with ADHD-C), administering a continuous performance test (TOVA), quantified electroencephalogram (Q-EEG), and nir-HEG. Results reflect the counterposed profiles hypothesis instead of the degrees of intensity, although the latter is more habitual and generalized.  相似文献

The approach to intervention programs varies depending on the methodological perspective adopted. This means that health professionals lack clear guidelines regarding how best to proceed, and it hinders the accumulation of knowledge. The aim of this paper is to set out the essential and common aspects that should be included in any program evaluation report, thereby providing a useful guide for the professional regardless of the procedural approach used. Furthermore, the paper seeks to integrate the different methodologies and illustrate their complementarity, this being a key aspect in terms of real intervention contexts, which are constantly changing. The aspects to be included are presented in relation to the main stages of the evaluation process: needs, objectives and design (prior to the intervention), implementation (during the intervention), and outcomes (after the intervention). For each of these stages the paper describes the elements on which decisions should be based, highlighting the role of empirical evidence gathered through the application of instruments to defined samples and according to a given procedure.  相似文献

Sexually transmitted infections (STIs) and HIV are important health problems that affect adolescents. The aim of the present study was to analyze the relationship between 1) depression, self-esteem and perceived social support and 2) sexual risk behaviors according to gender. The sample used in this ex post facto study was composed of 1,005 adolescents of both sexes aged between 14 and 18 years. Participants completed several questionnaires in the classrooms of their secondary education schools. The questionnaires assessed depression, self-esteem and perceived social support and recorded information on sexual behavior and socio-demographic issues. Results showed that, among males, self-esteem predicted higher vaginal risk, depression was related to higher vaginal, anal and oral sexual risk, and perceived support from the family predicted lower vaginal and anal sexual risk. Among females, self-esteem was found to be associated with lower anal sexual risk and perceived support from friends predicted lower anal and oral sexual risk. The study highlights the importance of considering family and friends as well as gender differences in the prevention of STIs/HIV.  相似文献

RESUMEN

Los autores comienzan su trabajo con una exposición de diversos alegatos a favor y en contra de los modelos multialmacén, considerando la validez de las pruebas en que se basan con referencia a los conceptos de capacidad, codificación y características del olvido, centrándose respecto a este último en la función de retención. Seguidamente proponen un marco alternativo en términos de niveles de procesamiento, manteniendo que el trazo de la memoria constituye un subproducto del análisis perceptivo y que su persistencia constituye una función positiva de la profundidad con la que se analiza el estímulo. Los autores reexaminan los datos existentes respecto al aprendizaje incidental, atención selectiva y almacén sensorial, distinción almacenamiento a corto/largo plazo, curva de posición serial y efectos de repetición y repaso. El trabajo termina aclarando que el enfoque de los autores no constituye una teoría sino más bien un marco conceptual con arreglo al cual podría proceder la investigación sobre memoria.  相似文献

Resumen

En este artículo se propone un cuerpo de conocimientos que hipotetizamos debería reunir la Psicología Diferencial Cognoscitiva. Esta propuesta tiene en consideración la relación entre los diversos enfoques de la Psicología Diferencial, tanto clásicos como más actuales, y la Psicología General, de acuerdo a tres metaniveles de teorización. Básicamente, la tesis mantenida en este artículo es que la psicología debería tender a elaborar modelos ajustados a las diferencias individuales en las actividades cognoscitivas tradicionalmente estudiadas por la psicología cognitiva, sea general o diferencial, y no tanto a buscar modelos canónicos referidos a dichas actividades.  相似文献

RESUMEN

Este artículo presenta diez experimentos diseñados para explorar el enfoque de la memoria humana en términos de niveles de procesamiento de la información propuesto por Craik y Lockhart (1972), en los que se inducía a los sujetos a que procesaran palabras a varias profundidades: a nivel superficial, intermedio y profundo. En la discusión general, los autores exponen varias razones por las que las concepciones originales de Craik y Lockhart parecen insatisfactorias, impulsando la idea de que la elaboración o “amplitud” de la codificación proporciona una mejor descripción de los resultados, además de señalar que la retención depende críticamente de los aspectos cualitativos de las operaciones de codificación ejecutadas. Por último, los autores afirman que parece necesario utilizar el “principio de congruencia” de Schulman (1974) para describir de una forma completa los efectos obtenidos y finalizan discutiendo las implicaciones generales de estos y otros experimentos.  相似文献
