Stress in Relation to Anxiety and Depression Among Racial/Ethnic Minority Women: The Differential Impact of Cultural Mismatch on Somatic and Cognitive Symptoms

The study examined the interactive effects of stress and cultural mismatch, as evidenced by low independent self‐construal, in relation to cognitive/somatic symptoms of anxiety and depression among racial/ethnic minority women. Results showed that stress and independent self‐construal work synergistically to differentially affect cognitive, rather than somatic, symptoms of anxiety and depression. Findings highlight the importance of investigating the interplay between stress and contextual factors to improve current treatment models for marginalized groups. El estudio examinó los efectos interactivos del estrés y la discordancia cultural, probados por un bajo autoconcepto independiente, en relación con los síntomas cognitivos/somáticos de la ansiedad y la depresión entre mujeres de minorías raciales/étnicas. Los resultados mostraron que el estrés y el autoconcepto independiente trabajan en sinergia para afectar diferencialmente a los síntomas cognitivos, no así a los somáticos, de la ansiedad y la depresión. Los hallazgos subrayan la importancia de investigar la interacción entre el estrés y los factores contextuales para mejorar los modelos de tratamiento actuales para grupos marginalizados.     

Latent Classes of Dysregulated Behaviors Relate to Negative Mental Images

Dysregulated behaviors (DBs), such as self-harm or binge eating, are related to various negative outcomes. In this study, we investigate how classes of individuals vary in their level of DBs. We compare the classes with regards to their experiences regarding negative mental images and emotion regulation strategies. A web-based survey assessed eleven DBs in a sample of N=912 adults. A latent class analysis (LCA) identified a class of 168 adults that were prone to various DBs (“high(DBs)”). Another class (n?=?46) reported drunkenness and risks for drug use and overeating (“high(Intake)”). The majority of individuals (n?=?698) featured a low rate of DBs (“low(DBs)”). The high(DBs) exhibited the highest scores in distressing imagery and maladaptive emotion regulation. The high(Intake) had a low overall profile; however, it displayed increased imagery nowness. Class differences were leveled by depressive symptoms. The findings help extend the knowledge on DBs and their correlates. Clinical implications are discussed.     

Inverted U-Shaped Function Between Flow and Cortisol Release During Chess Play

This study focused on the salivary cortisol level and its relation to the two components of flow (flow absorption and flow fluency) in tournament chess players exposed to one of the skill-demand-level manipulations (underload, fit, and overload). The aims of this study were to investigate how skill-demand-level manipulations affect cortisol release and how flow and cortisol release are related in the context of an engaging task. Specifically, the task involved fifty-seven tournament chess players playing chess against a software in one of the experimental groups. We assessed flow after chess playing for 25 min via questionnaire and collected saliva before chess playing (T1), right after chess playing (T2), and 10 min after T2 (T3). Our findings show that cortisol levels were affected by the skill-demand-level manipulations. At T3, participants in the overload group showed higher cortisol levels than participants in the fit and underload groups. There were no differences in cortisol release between the experimental groups at T2. In addition, we found the expected inverted U-shaped relation between cortisol release and flow absorption at T2. A moderate level of cortisol was associated with a higher level of flow absorption. In contrast, a higher level of cortisol was associated with a lower level of flow absorption. Against our expectations, flow fluency was not related to cortisol release. We discuss practical and theoretical implications of our results as well as potential for future research.     

Paradoxical sleep deprivation impairs acquisition, consolidation, and retrieval of a discriminative avoidance task in rats

The aim of the present study was to investigate the effects of paradoxical sleep deprivation (PSD) for 96 h on the learning/memory processes in rats submitted to the plus-maze discriminative avoidance task (PM-DAT), which simultaneously evaluates learning, memory, anxiety and motor function. Four experiments were performed in which rats were submitted to: (1) post-training and pre-test PSD; (2) post-training or pre-test PSD; (3) pre-training PSD or pre-training paradoxical sleep (PS) rebound (24 h) and (4) pre-test PSD rebound. Concerning Experiment I, post-training and pre-test PSD induced memory deficits, an anxiolytic-like behavior and an increase in locomotor activity. In Experiment II, both post-training PS-deprived and pre-test PS-deprived groups showed memory deficits per se. However, only the pre-test PS-deprived animals presented anxiolytic-like behavior and increased locomotor activity. In Experiment III, pre-training PS-deprived rats showed learning and memory deficits, anxiolytic-like behavior and increased locomotor activity. A 24h-sleep recovery period after the PSD abolished the learning and memory deficits but not anxiety and locomotor alterations. Finally, sleep rebound did not modify acquisition (Experiment III) and retrieval (Experiment IV). This study strengthened the critical role of paradoxical sleep (but not sleep rebound) in all the phases of learning and memory formation. In addition, it suggests that PSD effects on acquisition and consolidation do not seem to be related to other behavioral alterations induced by this procedure.     

Detecting changes in simulated events using partial‐interval recording and momentary time sampling

In a series of three studies, we evaluated simulated data with reversal designs to determine whether partial‐interval recording (PIR) and momentary time sampling (MTS) detected changes that were evident with continuous measures. The results from Study 1 showed that MTS with interval sizes up to 30 s detected most of the moderate and large changes in duration events and MTS with interval sizes up to 1 min detected most large changes in duration events. By comparison, PIR with 10‐s intervals detected approximately half of all changes in duration events. The results of Study 2 showed that only 10‐s PIR reliably detected most small, moderate, and large changes in frequency events. The results of Study 3 showed that PIR with 10‐s intervals generated a relatively high percentage of false positives for duration events, whereas MTS did not. As a whole, the results support previous findings, but also provide new guidelines for the use of PIR and MTS. Copyright © 2008 John Wiley & Sons, Ltd.     

Predicting compulsive Internet use: it's all about sex!

The objective of this research was to assess the predictive power of various Internet applications on the development of compulsive Internet use (CIU). The study has a two-wave longitudinal design with an interval of 1 year. The first measurement contained 447 adult heavy Internet users who used the Internet at least 16 h per week and had Internet access at home for at least 1 year. For the second measurement, all participants were invited again, of whom 229 responded. By means of an online questionnaire, the respondents were asked about the time spent on various Internet applications and CIU. On a cross-sectional basis, gaming and erotica seem the most important Internet applications related to CIU. On a longitudinal basis, spending a lot of time on erotica predicted an increase in CIU 1 year later. The addictive potential of the different applications varies; erotica appears to have the highest potential.     

Psychological empowerment, job satisfaction and performance among Filipino service workers

The present study surveyed 954 employees and their supervisors to determine the relationship of empowerment with job satisfaction and performance in five different service sectors: hotels, food service, banking, call centers, and airlines. Psychological empowerment was positively correlated with both job satisfaction and performance. Although intrinsic motivation was associated with higher levels of empowerment and job satisfaction, contrary to hypothesis, intrinsic motivation did not moderate the relationship between empowerment and job satisfaction and performance. Men reported greater empowerment than women even when job level and performance were controlled for. Cross-industry analyses indicated differences in empowerment across different types of service sectors with employees in call centers reporting less empowerment compared to employees in hotel, airlines, food establishments, and banks.     

Psychological factors associated with poor hypertension control: differences in personality and stress between patients with controlled and uncontrolled hypertension

Only one-third of patients with hypertension under pharmacological treatment achieve the recommended blood pressure goals. Psychological factors could partially account for poor hypertension control through the existence of personality traits related to treatment compliance (e.g., self-discipline, deliberation, impulsiveness), and the fact that stress and some personality traits (e.g., anxiety, depression, anger expression, Type A) are involved in the etiology of some hypertension cases. This study was aimed at examining the differences in personality and stress between patients taking antihypertensive medications with controlled and uncontrolled hypertension. Results revealed that after controlling sex, age, and traditional variables associated with poor hypertension control, the uncontrolled hypertension group showed higher scores on impulsiveness, depression, anger expression-out, and stress, with differences ranging between medium and large (Hedges' g effect size = 0.77 to 1.08). These results support the hypothesized relationship between psychological factors and poor hypertension control.     

Smoking as subculture? Influence on Hispanic and non-Hispanic White women's attitudes toward smoking and obesity.

Cultural stereotypes might help explain why smoking is less prevalent among Hispanic than non-Hispanic White women, whereas obesity is more prevalent. Hispanic (n = 130) and non-Hispanic White (n = 114) women rated their thoughts and feelings regarding a female smoker and an overweight woman. Ethnicity did not influence evaluations, but attitudes toward smokers were more positive among more acculturated Hispanic women, F(1, 66) = 9.9, p < .01. Less acculturated women evaluated an overweight woman more positively than a smoker, F(1, 28) = 5.65, p < .05; more acculturated women did the opposite, F( 1, 36) = 5.92, p < .05. Smokers evaluated smokers more positively than overweight women, F(1, 86) = 40.8, p < .01; nonsmokers did the opposite, F(l, 138) = 7.7, p < .01. Personal body weight did not influence evaluations. Acculturation and smoking status appear to have a greater influence than ethnicity or weight status on women's attitudes toward smoking and weight.
