Analysis of the indicators of pathological Internet use in Spanish university students

Addiction to and problematic use of the Internet are relatively recent phenomena whose scope, characteristics and correlates have begun to receive increasing attention by clinicians and researchers alike. The purpose of this study was to examine the relationship between time spent connected to the Internet and the variables that indicate a pathological and addictive use of this technological resource. The sample was comprised of 1,301 university students of both sexes (927 women and 374 men), with ages ranging from 18 to 30 years old. The results showed that, although most people use the Internet appropriately, users who invest higher quantities of time in the Internet more frequently exhibit connection behavior that is controlled through negative reinforcement, a high degree of arousal when online, loss of control over connection behavior, changes in health-related habits, and interference in the social, family, academic, or work spheres. These findings suggest that excessive Internet use is associated with the onset of several problems that are similar to those associated with other behavioral and technological addictions.     

The Eating Attitudes Test (EAT-26): reliability and validity in Spanish female samples

This paper focuses on the validation of the Spanish form of the Eating Attitudes Test (EAT-26; Garner, Olmsted, Bohr & Garfinkel, 1982) across two studies. Participants in Study 1 were 778 females recruited from community settings (aged 12-21). Study 2 included 86 females recruited from clinical and 86 females from community settings (aged 12-35). Results from Principal and Simultaneous Component Analyses showed a unidimensional structure of the EAT-26 item scores. Reliability analyses supported the internal consistency of the scale. Study 1 also explores the ability of the EAT-26 to discriminate between subjects with Eating Disorder (ED), Symptomatic or Asymptomatic by means of ROC analyses and using results from the Questionnaire for Eating Disorder Diagnoses (Q-EDD; Mintz, O'Halloran, Mulholland, & Schneider, 1997) as criterion. The EAT-26 demonstrated good specificity but insufficient sensitivity to detect a full or partial ED. Study 2 explores the ability of the questionnaire to discriminate between subjects with and without ED. The EAT-26 demonstrated good specificity and moderate sensitivity to detect ED. Clinical and theoretical implications of these results are discussed.     

Gender differences in reported stress response to the loma prieta earthquake

Sex Roles - Previous research has consistently demonstrated that men and women differ in the expression of emotions such as depression, anxiety, and stress. However, little research has...     

Gender roles in relation to assertiveness and eysenckian personality dimensions: Replication with a spanish population sample

The objective of the present study was to evaluate the cross-national replicability of the usual pattern of associations observed in Anglo-Saxon samples between masculinity and femininity on the one hand and difficulty and distress in assertiveness and the major Eysenckian dimensions of personality on the other hand. Participants were 925 SpanishSs (54% females; and 95.5% “European or other white”). Both the masculinity theory of psychological well-being and the notion thathigh femininity would not be implicated in self-assessed psychologicaldistress ordysfunction were supported by the data. Higher-order analysis showed that masculinity loaded highly on Positive Affect, whereas femininity had its primary loading on Constraint. Tentative support was found for the femininity-humility hypothesis advanced by P. B. Zeldow, S. R. Clark, and D. C. Daugherty in 1985.     

The Anxiety Response: Concordance Among Components

Under social-evaluative stress, self-reported distress (cognitive and somatic symptoms), behavioral anxiety (motor, facial, verbal, and social), physiological arousal (heart rate and skin resistance), and task performance (cognitive and motor) were recorded. Concordance was selective and consistent across response systems. There were significant relationships among measures of cognitive aspects, and among those concerned with somatic aspects, but not between these two areas. Furthermore, concordance was much higher in high-than in low-trait/test-anxiety participants, who even exhibited reversed concordance. These differences are explained in terms of stronger physiological signals in high trait/test anxiety. Alternative interpretations involving perceiving and/or reporting internal threat-related information in low trait/test anxiety are discussed.     

SEM Based CARMA Time Series Modeling for Arbitrary N

This article explains in detail the state space specification and estimation of first and higher-order autoregressive moving-average models in continuous time (CARMA) in an extended structural equation modeling (SEM) context for N = 1 as well as N > 1. To illustrate the approach, simulations will be presented in which a single panel model (T = 41 time points) is estimated for a sample of N = 1,000 individuals as well as for samples of N = 100 and N = 50 individuals, followed by estimating 100 separate models for each of the one-hundred N = 1 cases in the N = 100 sample. Furthermore, we will demonstrate how to test the difference between the full panel model and each N = 1 model by means of a subject-group-reproducibility test. Finally, the proposed analyses will be applied in an empirical example, in which the relationships between mood at work and mood at home are studied in a sample of N = 55 women. All analyses are carried out by ctsem, an R-package for continuous time modeling, interfacing to OpenMx.     

Assessment of Conflicts Associated with a Traditional Masculine Gender Role in Spanish College Men and Women

The purpose of the present study was to investigate the psychometric properties of the Spanish version of the Gender Role Conflict Scale – Short Form (GRCS-SF; Wester et al. 2012) in a sample of men. In addition, we extend the gender conflict paradigm by evaluating two samples of women with the same instrument. In Study 1, we investigated the internal structure of the instrument in a sample of 281 Spanish undergraduate women using exploratory factor analysis, finding support to the original factor structure. In Study 2, we analyzed its psychometric properties in a college sample of 184 men and 255 women using confirmatory factor analysis, and we explored differences between the two genders through a factor invariance analysis and a comparison of group means. Sufficient equivalence was found, allowing for comparisons among men’s and women’s scores. Overall, masculine gender conflict was significantly associated with greater distress and less general subjective well-being in both men and women. Our research extends the gender role conflict paradigm to the Spanish context and enhances the study of women’s conflicts associated with the adoption of behaviors traditionally attributed to the male gender role.
