Consequences of job insecurity. The moderator role of organizational support from a multilevel perspective

Job insecurity is one of the main stressors for many employees. Hence, it is important to identify factors that can ameliorate its detrimental effects. In this respect, the present study examines the moderator role of organizational support, understood as a contextual factor in the relationship between job insecurity and its consequences. The sample comprised 859 employees from 42 Spanish organizations. Results showed that organizational support modulated the relationship between job insecurity and employees' reactions (i.e., job satisfaction, psychological health and intention to leave the organization). These results reveal the need to consider contextual factors such as organizational support in the study and intervention of job insecurity.     

Hormonal changes after competition predict sex‐differentiated decision‐making

Recent neuroendocrinology research has pointed out that testosterone (T) and cortisol (C) changes after social interactions can predict risk‐taking behavior in decision‐making, depending on the sex of participants. However, previous research has focused on the effects of the changes in only one hormone, rather than the interaction between them, even though C can suppress T activity. Our aim was to test, in men and women, the role of T changes moderated by C changes after competition in decision‐making. Thus, 48 males and 46 females completed the Iowa Gambling Task (IGT) after a laboratory competition or a noncompetitive task (control task). Saliva samples were collected before and after the competition/control task. IGT was employed to measure risk‐taking decision‐making, considering the degree of uncertainty. Our results showed sex‐differentiated effects of T and C changes on risk‐taking behavior. On the one hand, men from both task groups (Competition/Control) who had higher C and T changes after competition showed more risk‐taking decision‐making (higher IG Risk). On the other hand, women from the competitive task who had high C and T showed conservative decision‐making. Therefore, these results show sex‐differentiated decision‐making profiles, which would help to understand how men and women behave after experiencing a competitive social context.     

Association of daytime sleepiness and the morningness/eveningness dimension in young adult subjects in Brazil

Sleepiness is a major public health problem associated with motor vehicle crashes, occupational accidents, decreased productivity, and interpersonal problems. It can be influenced by many factors, including the individual's circadian rhythm. The objective of this study is to assess the correlation between the morningness/eveningness dimension and daytime sleepiness in medical school students. This is a cross-sectional study; 310 subjects (123 women and 187 men, M age 20.5 +/- 1.9 yr.) completed a questionnaire on use of drugs, diagnostic diseases, sleeping habits, the Morningness/Eveningness Questionnaire and the Epworth Sleepiness Scale. The only variable related to daytime sleepiness was the morningness/eveningness dimension (r = -.18, p=.002). Questions with higher coefficients of discrimination between the morning and the evening chronotype were "Lying down to rest in the afternoon when circumstances permit" (.61), "Sitting and reading" (.53), and "As a passenger in a car for an hour without a break" (.53). The implications of the findings are discussed.     

The List of Social Situation Problems: Reliability and Validity in an Adolescent Spanish-Speaking Sample

The aim of this study was to analyze the psychometric properties of the Spanish translation of the List of Social Situation Problems (LSSP; S. H. Spence, 1980). The questionnaire was administered to a sample of 388 adolescents between the ages of 12 and 18. Exploratory factor analysis identified four factors: Social Anxiety, Adult Oppositional, Assertiveness, and Making Friends, which accounted for 26.64% of the variance. Internal consistency of the total scale was high ( = .86). Correlations between the LSSP and two self-report measures of social anxiety, the Questionnaire about Interpersonal Difficulties for Adolescents (r = .45) and the Social Phobia and Anxiety Inventory (r = .48), were statistically significant. A significant difference was found between LSSP total scores for adolescents with and without social anxiety (d = 1.14), supporting the construct validity of the scale.     

Rapid eye movement sleep dreaming is characterized by uncoupled EEG activity between frontal and perceptual cortical regions

EEG coherent activity is involved in the binding of spatially separated but temporally correlated stimuli into whole events. Cognitive features of rapid eye movement sleep (REM) dreaming resemble frontal lobe dysfunction. Therefore, temporal coupling of EEG activity between frontal and perceptual regions was analyzed from 10 min prior to dream reports (8 adults) from stage-2 and REM sleep. EEG correlation between frontal and perceptual regions decreased and, among perceptual regions increased during REM. The temporal dissociation of EEG activity between executive and perceptual regions supplies an inadequate mechanism for the binding and interpretation of ongoing perceptual activity resulting in dream bizarreness.     

Age-related changes and gender differences in time estimation

A study was carried out in which age and gender differences were studied in the performance of an empty interval production task. The duration of these intervals was 10 s, 1 and 5 min. The sample was made up of 140 subjects, half male and half female, in seven different age groups from 8 to 70 years old. The age range permitted us to identify when differences begin to be significant. The results show an age-related increase in the underproduction of the intervals. The differences between age groups attained significance from 51 to 60 years onward. With regard to gender, the main result was a greater underproduction of longer intervals (1 and 5 min) for women. These findings were interpreted in terms of different models of time estimation.     

Cohesion and adaptability among individuals under treatment for infertility

The objective of this study was to evaluate cohesion and adaptability as relationship patterns of individuals in the presence or absence of infertility. Infertile subjects (20 men and 26 women, age 29.9 yr., SD = 3.8), and 100 fertile individuals (52 men and 48 women, age 29.5 yr., SD = 3.6) were included in this cross-sectional study conducted in Brazil. Subjects were married for the first time and had no children. The pattern of relationship (cohesion and adaptability) was assessed on the Family Adaptability and Cohesion Evaluation Scale (FACES III). Subjects were also interviewed and the interviews tape-recorded and analyzed by independent and blinded senior psychiatrists. The concepts of cohesion and adaptability did not differentiate infertile couples from fertile ones. Further, the recorded interviews also resulted in heterogeneous. nonconcordant judgments. These results lead to two conclusions: that awareness of infertility is not present in the population studied or that it is present but the magnitude of its effect is quite small and that FACES III and the interview focus on adaptability and cohesion are not sensitive enough to measure the difficulties in these couples' relationships. This leads us to reflect on the type of psychiatric support available to infertile couples.     

A Phenomenological Approach to the Study of Social Distance

Being an optimist or a pessimist and its relationship with morning cortisol release and past life review in healthy older people

Objective: Investigate the relationship between optimism and pessimism and the cortisol awakening response (CAR) and past life review in healthy older people.

Design: 76 older volunteers summarised their lives, highlighting the most important events, impressions and experiences. Cortisol saliva samples were collected on two consecutive weekdays. High and low optimism and pessimism groups were computed by mean split.

Main Outcome Measures: Percentages of positive (PE) and negative events (NE) and positive (PCE) and negative cognitions and emotions (NCE) were obtained. Optimism and pessimism were measured with the Life Orientation Test Revised. The areas under the curve with respect to the ground and with respect to the increase were computed, with the latter understood as the CAR.

Results: The high pessimism group reported more NE and NCE and less PE and PCE (p’s < 0.041). No significant differences in CAR were found between high and low optimism and pessimism groups after removing suspected non-adherent participants (p’s > 0.116). Higher CAR was related to lower PCE, but higher NCE (both p < 0.008).

Conclusion: Pessimism seems to increase the focus on negative aspects of the past, which may lead to a worse perception of life in ageing, whereas optimism contributes to a healthier CAR.     

Dimensional structure of the Brief Symptom Inventory with Spanish college students

The Brief Symptom Inventory is designed to assess symptoms of psychological disorders in adolescents and adults. The dimensional structure of the inventory, using exploratory and confirmatory factor analyses, was examined with a cross-sectional design in a Spanish sample of college students ( N = 1,033, aged between 18 and 30 years old). Two hypotheses were tested: the original distribution of the items in nine factors, and the unidimensionality of the inventory. According to the results, a nine-factor structure seemed to be confirmed, although the strong intercorrelations found among the subscales indicated that these were measuring closely related constructs. The importance of cultural influences when assessing psychological symptoms and the need to develop national and sex norms for instruments that assess psychopathology, are also discussed.
