Experience of stress in childhood negatively correlates with plasma oxytocin concentration in adult men

Early life experience is known to affect responses to stress in adulthood. Adverse experience in childhood and/or adolescence sensitises to life events that precipitate depression in later life. Published evidence suggests a relationship between depression and oxytocin (OT), but the extent to which early life experience influences OT disposition in adulthood deserves further exploration. This study hypothesised that early life stress (ELS) has a long-term negative effect on OT system activity. The study was performed on 90 male volunteers (18-56 years; mean ± standard deviation = 27.7 ± 7.09 years). Several questionnaires were used to assess: health, early life stressful experiences in childhood (ELS-C, up to 12 years) and early life stressful adolescence (13-18 years), recent stressful life events, depressive symptoms, state-trait anxiety and social desirability. Plasma OT concentration was estimated by means of a competitive enzyme immunoassay. Lower OT concentrations were significantly associated with higher levels of ELS-C (p < 0.01), and with depressive symptoms and trait anxiety (both p < 0.05). The interaction between ELS-C and trait anxiety was significant (p < 0.05), indicating that the link between ELS-C and plasma OT concentration is moderated by trait anxiety. These results contribute to the evidence that early life adverse experience is negatively associated with OT system activity in adulthood, and offer further insight into mediator and moderator effects on this link.     

Emotion regulation through listening to music in everyday situations

Music is a stimulus capable of triggering an array of basic and complex emotions. We investigated whether and how individuals employ music to induce specific emotional states in everyday situations for the purpose of emotion regulation. Furthermore, we wanted to examine whether specific emotion-regulation styles influence music selection in specific situations. Participants indicated how likely it would be that they would want to listen to various pieces of music (which are known to elicit specific emotions) in various emotional situations. Data analyses by means of non-metric multidimensional scaling revealed a clear preference for pieces of music that were emotionally congruent with an emotional situation. In addition, we found that specific emotion-regulation styles might influence the selection of pieces of music characterised by specific emotions. Our findings demonstrate emotion-congruent music selection and highlight the important role of specific emotion-regulation styles in the selection of music in everyday situations.     

The role of emotion in bridging the intention–behaviour gap: The case of sports participation

ProblemPsychological models of sports participation frequently draw on the Theory of Planned Behaviour (TPB) in order to predict health-behaviour-related intentions. While these models commonly show high predictive power with respect to intention, they often fall short in the prediction of behaviour (the ‘intention–behaviour gap’). The present study contends that integrating emotional processes into TPB can substantially improve the model's predictive power over and above traditional cognitive predictors.MethodIn a longitudinal study structural equation modelling was employed to test a traditional model (based on TPB) and an extended model including emotion associated with the intention to exercise as a mediator variable. A community sample (N = 237) completed a questionnaire measuring the components of a traditional TPB model. Prior to each of 16 expected exercise sessions (over 8 weeks) intention to exercise and emotion associated with the intention were measured.ResultsResults confirmed a substantial increase of 17% in explained variance of exercise frequency and 20% in exercise duration for the extended model. Emotional appraisal of the intention to exercise thus appears to mediate the traditional intention–behaviour relationship, suggesting that emotionally based interventions aimed at increasing sports participation may be helpful.ConclusionIt is concluded that emotion variables should be added to traditional TPB models in order to predict health behaviour more fully.

Emotional suppression explains the link between early life stress and plasma oxytocin

Early life stress (ELS) has been found to be associated with lower concentrations of plasma oxytocin (OT) in adulthood. It is not yet clear, however, what mechanisms underlie this association. The goal of the present study was to test the role of emotional suppression as an intervening variable between ELS in childhood and plasma OT. In a nonclinical sample of 90 men, ELS, emotional suppression, and plasma OT were assessed. Emotional suppression was positively associated with ELS (r = 0.37, p < 0.001) and negatively associated with plasma OT concentrations (r = ?0.30, p < 0.01). In contrast, cognitive reappraisal – an alternative emotion regulation strategy – was not correlated with ELS or plasma OT concentrations. Cross-sectional regression analyses revealed that the ELS explained variance in plasma OT via emotional suppression. Moderation analyses revealed that the combination of high ELS and high emotional suppression was associated with the lowest concentrations of plasma oxytocin. These findings are consistent with the view that emotional suppression may be one pathway linking ELS and OT.     

Effect of an Emotion Regulation Training Program on Mental Well-Being

This study aimed to develop and validate a brief emotion regulation training program that improved mental well-being. The program was preventative in nature, designed to build resilience while fostering more satisfying personal and professional relationships in a community sample. It was developed and piloted with 10 graduate students during Study 1; for Study 2, a community sample of 75 adults were randomly allocated to either a treatment (n = 38) or control (n = 37) group. In the pilot program, the social validity of the program was confirmed, while study 2 demonstrated significant changes in positive coping techniques (i.e., reappraisal) at one-year follow-up in the treatment group when compared with the control. These findings may have broad implications in the health sector due to the brevity, scalability, and cost-effectiveness of this newly designed intervention.     

The Effect of Holy Qur’an Recitation on Depressive Symptoms in Hemodialysis Patients: A Randomized Clinical Trial

Patients with advanced renal failure often face considerable sociopsychological stress as a result of lifestyle changes due to the disease and its treatment. The aim of the present study is to examine the effect of the Holy Qur’an recitation on depressive symptoms in hemodialysis patients. In this clinical trial, 54 hemodialysis patients were randomized to either an experimental (n = 27) or a control (n = 27) group. Patients completed the Beck Depression Inventory-II (BDI-II) at baseline and at 1 month after the intervention. Participants in the experimental group listened to recitation of the Holy Qur’an, while those in the control group received no intervention. The mean BDI-II score at baseline was 33.6 (±6.7) for the experimental group and 29.3 (±9.0) for the control group; at the end of treatment, BDI-II scores in the experimental and control groups were 14.5 (±4.8) and 31.6 (±9.2), respectively. Results from the repeated-measures general linear model controlling for baseline differences indicated a significant treatment effect (F = 9.30, p = 0.004, Cohen’s d = 0.85). Holy Qur’an recitation has a significant effect on lowering depressive symptoms in hemodialysis patients. Holy Qur’an recitation is an easy-to-implement and cost-effective strategy that may be used to supplement the treatment of depression in this setting in Iran.

     

Test of Nyborg's General Trait Covariance (GTC) model for hormonally guided development by means of structural equation modeling

Nyborg's General Trait Covariance (GTC) model for hormonally guided development investigates the influence of gonadal hormones and fluid intelligence on body build, achievement, and socioeconomic variables. According to the model, testosterone should be negatively related to height, fat/muscle ratio, intelligence, income, and education. It is conceived that this influence should be determined to a great extent by mutual relationships between these variables. The model was tested by means of structural equation modeling (SEM) in a sample of 4375 males who had served in the United States Armed Forces. The results largely confirm Nyborg's androtype model but in addition reflect the relationships between the variables included in a quantitative causal manner. It could be shown that testosterone has a negative influence on crystallized intelligence and that this effect is mainly mediated by the negative influence of testosterone on education. An additional multiple group analysis testing for structural invariance across age groups revealed that the mediating role of education is more pronounced in old veterans.
