Nocturnal polysomnographic correlates of daytime sleepiness

The relations of nighttime polysomnographic sleep variables with daytime sleepiness scores on the Epworth Sleepiness Scale were assessed in a retrospective chart review of 38 patients referred to a sleep clinic. Of the variables assessed, only slow wave sleep was statistically significantly correlated with daytime sleepiness, regardless of whether the analysis was based on absolute minutes of slow wave sleep or percentage of total sleep time spent in slow wave sleep. Stepwise linear regression suggested that other polysomnographic variables did not provide additional predictive value beyond the two indices of slow wave sleep. Apparently, reduced quantity of slow wave sleep was weakly but significantly related to increased daytime sleepiness among these sleep-clinic patients.     

Psychometric properties of the state-trait anxiety inventory for Asian/Pacific-islander adolescents

Anxiety disorders are said to be universal across all cultures and recent reviews have found relatively high prevalence rates across different countries. However, the experience and interpretation of anxiety are strongly influenced by cultural factors. Demonstrating cross-cultural equivalence of measures of anxiety is essential to assure that comparisons between cultures will result in meaningful interpretations. Despite the State-Trait Anxiety Inventory being the most researched of anxiety measures from a cross-cultural basis, there is a lack of empirical studies on the psychometric properties of the STAI with adolescent Asian/Pacific Islanders. The present study examined the STAI using a large sample of ethnically diverse high school students in Hawaii. In general, a four-factor model (State-Anxiety Absent, State-Anxiety Present, Trait-Anxiety Absent, and Trait-Anxiety Present) provided the best fit based on a series of confirmatory factor analyses. Indicators of internal consistency supported the reliability of the factors and subscales, and the inter-factor correlations reflected positively on the concurrent validity of the different STAI factor and subscale measures. This study suggested cautious use and interpretation of one particular item (Trait Item 14 = I try to avoid facing a crisis or difficulty ), and cautious application of the STAI to Filipino adolescents (particularly Filipino males). Domains for further research are discussed.     

Stereotypes and beliefs about different ethnic groups in Spain. A study with Spanish and Latin American children living in Madrid

96 Spanish and Latin American children from 3 grades in Madrid reported their knowledge of positive and negative stereotypes regarding Spaniards, Gypsies, Latin American and Chinese people. Their personal beliefs about these four ethnic groups were also assessed. Stereotypes about Spaniards were perceived as overwhelmingly positive and least negatively while stereotypes about Gypsies were rarely positive and often negative. Spanish children attributed more positive and fewer negative stereotypes to Chinese immigrants than Latin American children did. Older children reported more positive stereotypes about Gypsies than younger children and older Spanish children reported fewer positive stereotypes for their own group than their younger counterparts. Older children's personal beliefs about Gypsies were less consistent with negative stereotypes than younger children's. Older children also showed greater discrepancy of their personal beliefs with positive stereotypes of Spaniards than younger children did. Findings are discussed within the context of socio-cognitive approaches.     

Tangibles as predictors of customer satisfaction in sports services

This study investigates the power of tangible dimensions of service quality to predict customer satisfaction. For this purpose, we statistically controlled the effects of dimensions of service quality that describe social interaction between employees and customers, both functionally and relationally. A field survey was conducted with the participation of 556 customers of a sports centre. The results showed that tangible dimensions of service quality predicted an additional and significant amount of customer satisfaction variance, beyond the effects of service quality of the social interaction. The article concludes with the discussion of the implications of these results.     

Changing circumstances, disrupting habits

The present research investigated the mechanisms guiding habitual behavior, specifically, the stimulus cues that trigger habit performance. When usual contexts for performance change, habits cannot be cued by recurring stimuli, and performance should be disrupted. Thus, the exercising, newspaper reading, and TV watching habits of students transferring to a new university were found to survive the transfer only when aspects of the performance context did not change (e.g., participants continued to read the paper with others). In some cases, the disruption in habits also placed behavior under intentional control so that participants acted on their current intentions. Changes in circumstances also affected the favorability of intentions, but changes in intentions alone could not explain the disruption of habits. Furthermore, regardless of whether contexts changed, nonhabitual behavior was guided by intentions.     

Self-regulation of Gendered Behavior in Everyday Life

The present research tested whether gender self-concepts influence behavior through self-regulatory processes, with emotions and self-esteem signaling that people’s responses meet or fail to meet their gender standards. In the first study, cross-sectional survey data from 3,174 young adults living in the United States revealed that esteem increased with behavioral conformity to gender standards for personality. In the second study, an experience-sampling diary design provided a dynamic view of regulation to gender standards for personality and romance. One hundred seventy-seven American undergraduates reported their emotions and esteem immediately following everyday social interactions. As anticipated, students became more positive when they acted in ways that confirmed rather than disconfirmed personal gender standards.     

Brief Report: Physician Narcissism,Ego Threats,and Confidence in the Face of Uncertainty

Although adequate self‐esteem is essential for psychological health, people with high but fragile self‐esteem have been shown to exhibit defensive, often aggressive behavior when their self‐esteem is threatened. We measured physician narcissism (as a proxy for high but fragile self‐esteem) and used a subtle manipulation to examine how physicians who varied in levels of narcissism responded to an ego threat. We found that physicians high in narcissism, as compared with those lower in narcissism, were more likely to respond to ego threat by attempting to bolster their self‐image. Concerned about self‐image, physicians in this situation may be insufficiently receptive to new information and instead attempt to justify initial opinions.
