Depressive symptoms during pregnancy: impact on neuroendocrine and neonatal outcomes

Objective

To explore the interplay of maternal depressive symptoms on the infant limbic-hypothalamic-pituitary axis (LHPA) and neurological development.

Design

Pregnant women were monitored for depressive symptoms using the Beck Depression Inventory (BDI) at 28, 32, and 37 weeks of gestation and at delivery. A mixture growth curve analysis divided the women into three risk groups: low/stable, intermediate, and high/increasing depression based on BDI scores. The infant neuroendocrine system was examined using cord blood for adrenocorticotrophic hormone (ACTH) and cortisol measurements. Two-week-old infants were examined using Neonatal Intensive Care Unit Neurobehavioral Scale (NNNS).

Results

Infants born to women of the high/increasing depression group had significant ACTH elevation at birth. On NNNS examination, these infants were more hypotonic and habituated to auditory and visual stimuli.

Conclusion

When compared to non-depressed women, maternal depressive symptoms, even in the absence of major depressive disorder, appeared to facilitate a different developmental pathway for the infant LHPA and early neurological development.     

Perceived Stress in Young Carers: Development of a Measure

We report the development of a 5-factor, 31-item, Young Carers Perceived Stress Scale (YCPSS) from an initial 50-item pool. The scale was developed and tested on 108 young carers aged between 12–18 years, and acceptable Cronbach Alpha values were obtained for the individual factors and the overall scale. In addition, both the overall scale and individual factors produced a pattern of correlations with social support, burden of care, psychological distress, and coping, supporting the initial validity and utility of the scale.     

The well-being of Romanian workers in Spain: antecedents and moderators

This study adds to our understanding of the negative effect that job insecurity (JI) has over the well-being of migrating workers. The moderating effect of acculturation and support for family was investigated while considering engagement, burnout and physical and psychological health as criteria, in a sample of 477 Romanian employees who work in Spain. Results show that acculturation buffers against the negative effects of JI on engagement, and it attenuates the relationship between JI and burnout or mental health complaints. Support for family has no intervening effect between JI and well-being outcomes. In a three-way JI × support for family × acculturation interaction, JI had a positive relationship with burnout, when migrating workers were married and experienced a low level of acculturation. The findings are of value because they emphasize the importance of acculturation for the occupational health of migrating workers.     

The impact of inhibition capacities and age on number–space associations

Numerical and spatial representations are tightly linked, i.e., when doing a binary classification judgment on Arabic digits, participants are faster to respond with their left/right hand to small/large numbers, respectively (Spatial-Numerical Association of Response Codes, SNARC effect, Dehaene et al. in J Exp Psychol Gen 122:371–396, 1993). To understand the underlying mechanisms of the well-established SNARC effect, it seems essential to explore the considerable inter-individual variability characterizing it. The present study assesses the respective roles of inhibition, age, working memory (WM) and response speed. Whereas these non-numerical factors have been proposed as potentially important factors to explain individual differences in SNARC effects, none (except response speed) has so far been explored directly. Confirming our hypotheses, the results show that the SNARC effect was stronger in participants that had weaker inhibition abilities (as assessed by the Stroop task), were relatively older and had longer response times. Interestingly, whereas a significant part of the age influence was mediated by cognitive inhibition, age also directly impacted the SNARC effect. Similarly, cognitive inhibition abilities explained inter-individual variability in number–space associations over and above the factors age, WM capacity and response speed. Taken together our results provide new insights into the nature of number–space associations by describing how these are influenced by the non-numerical factors age and inhibition.     

You can say what you think: vindicating the effability of our thoughts

The thesis of Ineffability has it that no proposition can be fully expressed by a sentence, this meaning that no sentence-type, or even sentence-token whose indexicality and ambiguities have been resolved, can fully encode a proposition. The thesis of the propositionality of thoughts has it that thoughts are propositional. An implication of the joint endorsement of these two theses is that thoughts are ineffable. The aim of this paper is to argue that this is not the case: there are effable thoughts, and we can even safely say that, generally, thoughts are effable. In order to defend this insight, I first counter the thesis of the propositionality of thought by bringing some counterexamples to it, which amount to cases of non-fully propositional thought. I then argue that, if thoughts can be and often are non-fully propositional, they can be expressed by sentences that fail to fully express a proposition. I also show that the propositional thoughts that we can entertain are after all effable (in a suitable, relevant sense) and resist some alleged examples of insurmountable ineffability.     

The Satisfaction with Life Scale in Adolescent Samples: Measurement Invariance across 24 Countries and Regions,Age, and Gender

Measurement of adolescent life satisfaction across cultures has not received much attention in previous empirical research. The present study evaluated measurement invariance of the Satisfaction with Life Scale (SWLS) among adolescents in 24 countries and regions (N = 22,710; age range = 13–19 years; 53% female). A single-factor model with residual covariance between a pair of items tapping past life satisfaction fitted well in 19 countries and regions and showed a partial metric invariance. In a subset of nine countries and regions, partial scalar invariance was supported. Partial metric invariance across all 24 countries and regions was achieved when custom model modifications in five countries and regions were included. Three SWLS items showed evidence of noninvariance across cultures. The measurement model was found to operate similarly across gender and age. Our findings suggest that caution is needed when using the SWLS for measuring life satisfaction among adolescents from different cultures.

     

Sensory awareness versus sensory impression: Affect and attention interact to produce somatic meaning

Abstract

Contrary to the assumptions of common sense—and of some research—focusing on one's physical sensations does not necessarily make them more unpleasant. Rather, attention and affect interact to produce somatic meaning. Fifty-six male subjects exercised at 60% of their aerobic capacity with either no instructions, or instructions to closely monitor their somatic sensations. Half of each group thought they might receive an electric shock while they exercised. Subjects then listed the sensations they perceived, and indicated their degree of noticeability, their subjective unpleasantness, and their presumed cause. Monitoring subjects reported the same number of physical sensations as did the no-instruction subjects, and rated them as noticeable to the same degree. Nonetheless, monitoring produced a more negative interpretation of one's sensations under threat, but a more positive one under no threat. The findings support and extend the view of somatic experience as inherently plastic. The results also suggest that sensory attention can influence the meaning of somatic information—in both a positive and a negative direction—without necessarily imparting more of it.
