Psychological contract development: An integration of existing knowledge to form a temporal model

The psychological contract has received substantial theoretical attention over the past two decades as a popular framework within which to examine contemporary employment relationships. Previous research mostly examines breach and violation of the psychological contract and its impact on employee organization outcomes. Few studies have employed longitudinal, prospective research designs to investigate the psychological contract and as a result, psychological contract content and formation are incompletely understood. It is argued that employment relationships may be better proactively managed with greater understanding of formation and changes in the psychological contract. We examine existing psychological contract literature to identify five key factors proposed to contribute to the formation of psychological contracts. We extend the current research by integrating these factors for the first time into a temporal model of psychological contract development.

Predicting psychological and subjective well-being from personality: incremental prediction from 30 facets over the Big 5

This study investigated the relationship between the Big 5, measured at factor and facet levels, and dimensions of both psychological and subjective well-being. Three hundred and thirty-seven participants completed the 30 Facet International Personality Item Pool Scale, Satisfaction with Life Scale, Positive and Negative Affectivity Schedule, and Ryff’s Scales of Psychological Well-Being. Cross-correlation decomposition presented a parsimonious picture of how well-being is related to personality factors. Incremental facet prediction was examined using double-adjusted r2 confidence intervals and semi-partial correlations. Incremental prediction by facets over factors ranged from almost nothing to a third more variance explained, suggesting a more modest incremental prediction than presented in the literature previously. Examination of semi-partial correlations controlling for factors revealed a small number of important facet-well-being correlations. All data and R analysis scripts are made available in an online repository.

The influence of psychological factors on post-partum weight retention at 9 months

Design Therefore, the aim of this study was to explore the relationship between post-partum psychological distress and PWR at 9 months, after controlling for maternal weight factors, sleep quality, sociocontextual influences, and maternal behaviours. Method Pregnant women (N = 126) completed a series of questionnaires at multiple time points from early pregnancy until 9 months post-partum.

The effect of overweight/obesity on cardiovascular responses to acute psychological stress in men aged 50-70 years.

To determine the effect of adiposity in males aged 50-70 years on cardiovascular responses to acute psychological stress.

Psychological management of unipolar depression

Objective: To be used in conjunction with 'Pharmacological management of unipolar depression' [Malhi et al. Acta Psychiatr Scand 2013;127(Suppl. 443):6-23] and 'Lifestyle management of unipolar depression' [Berk et al. Acta Psychiatr Scand 2013;127(Suppl. 443):38-54]. To provide clinically relevant recommendations for the use of psychological treatments in depression derived from a literature review. Method: Medical databases including MEDLINE and PubMed were searched for pertinent literature, with an emphasis on recent publications. Results: Structured psychological treatments such as cognitive behaviour therapy and interpersonal therapy (IPT) have a robust evidence base for efficacy in treating depression, even in severe cases of depression. However, they may not offer benefit as quickly as antidepressants, and maximal efficacy requires well-trained and experienced therapists. These therapies are effective across the lifespan and may be preferred where it is desired to avoid pharmacotherapy. In some instances, combination with pharmacotherapy may enhance outcome. Psychological therapy may have more enduring protective effects than medication and be effective in relapse prevention. Newer structured psychological therapies such as mindfulness-based cognitive therapy and acceptance and commitment therapy lack an extensive outcome literature, but the few published studies yielding positive outcomes suggest they should be considered options for treatment. Conclusion: Cognitive behaviour therapy and IPT can be effective in alleviating acute depression for all levels of severity and in maintaining improvement. Psychological treatments for depression have demonstrated efficacy across the lifespan and may present a preferred treatment option in some groups, for example, children and adolescents and women who are pregnant or postnatal. © 2013 John Wiley & Sons A/S.

My road ahead study protocol: a randomised controlled trial of an online psychological intervention for men following treatment for localised prostate cancer

There is a need for psychosocial interventions for men with prostate cancer to promote adaptive coping with the challenges and distress associated with diagnosis, treatment and recovery. In addition, interventions are needed that help to overcome barriers to psychosocial treatment such as limited face-to-face psychosocial support services, a shortage of adequately trained professionals, geographical distance, perceived and personal stigma and a preference for consumer-centric and self-directed learning. My Road Ahead is an online cognitive behaviour therapy (CBT) intervention for prostate cancer. This protocol describes a randomised controlled trial (RCT) that will evaluate the efficacy of this online intervention alone, the intervention in combination with a moderated online forum, and the moderated online forum alone.

Preliminary results of a randomised controlled trial of an online psychological intervention to reduce distress in men treated for localised prostate cancer

Prostate cancer (PCa) poses many emotional and physical challenges for men following treatment. The unmet support needs of these men are well documented, and access to psychosocial support remains problematic.

Effect of ECG-derived respiration (EDR) on modeling ventricular repolarization dynamics in different physiological and psychological conditions

Ventricular repolarization dynamics is an important predictor of the outcome in cardiovascular diseases. Mathematical modeling of the heart rate variability (RR interval variability) and ventricular repolarization variability (QT interval variability) is one of the popular methods to understand the dynamics of ventricular repolarization. Although ECG derived respiration (EDR) was previously suggested as a surrogate of respiration, but the effect of respiratory movement on ventricular repolarization dynamics was not studied. In this study, the importance of considering the effect of respiration and the validity of using EDR as a surrogate of respiration for linear parametric modeling of ventricular repolarization variability is studied in two cases with different physiological and psychological conditions. In the first case study, we used 20 young and 20 old healthy subjects’ ECG and respiration data from Fantasia database at Physionet to analyze a bivariate QT–RR and a trivariate QT–RR–RESP or QT–RR–EDR model structure to study the aging effect on cardiac repolarization variability. In the second study, we used 16 healthy subjects’ data from drivedb (stress detection for automobile drivers) database at Physionet to do the same analysis for different psychological condition (i.e., in stressed and no stress condition). The results of our study showed that model having respiratory information (QT–RR–RESP and QT–RR–EDR) gave significantly better fit value (p < 0.05) than that of found from the QT–RR model. EDR showed statistically similar (p > 0.05) performance as that of respiration as an exogenous model input in describing repolarization variability irrespective of age and different mental conditions. Another finding of our study is that both respiration and EDR-based models can significantly (p < 0.05) differentiate the ventricular repolarization dynamics between healthy subjects of different age groups and with different psychological conditions, whereas models without respiration or EDR cannot distinguish between the groups. These results established the importance of using respiration and the validity of using EDR as a surrogate of respiration in the absence of respiration signal recording in linear parametric modeling of ventricular repolarization variability in healthy subjects.
