Modeling Psychological Contract Violation using Dual Regime Models: An Event-based Approach

Psychological contract breach during the pandemic: How an abrupt transition to a work from home schedule impacted the employment relationship

Organizations shifted employees to a work from home schedule as a protective health measure during the COVID-19 pandemic. This paper depicts the path through which the abrupt workplace disruptions can trigger employees' perceptions of felt mistrust, intensify work to life conflict, and cause a psychological contract breach. In study 1, we conducted an experiment with 133 college students and found that switching to a work from home schedule with enhanced supervisor control increased the psychological contract breach through felt mistrust. In Study 2, we surveyed 239 adults who worked from home during the pandemic. Results underline the role of work to life conflict as a mediator through which disruptions and felt mistrust influenced the breach of psychological contract. Further, coping strategies were found to mitigate this detrimental effect. Overall, our findings suggest that sudden shifts in management practices can challenge workplace relationships during environmental shocks.

Sexual Minority Stressors and Intimate Partner Violence Among Same-Sex Couples: Commitment as a Resource

Accumulating evidence has been found for the associations from sexual minority stressors to intimate partner violence (IPV) among same-sex couples. Yet key gaps still exist, including the rare utilization of couple dyadic data, the understudied moderating and mediating mechanisms, and the few studies conducted during the transitional period of same-sex marriage legalization. To address these gaps, we used cross-sectional, dyadic data collected from 144 US same-sex couples during the 2014-2015 national campaign for the legalization of same-sex marriage. Guided by the systemic transactional model (STM), we examined associations from sexual minority stressors (including both internalized homophobia and discrimination) to same-sex IPV and tested whether commitment moderated or mediated these associations. Overall, we found evidence supporting the STM: (1) High internalized homophobia and discrimination were related to high prevalence and/or frequency of IPV perpetration; (2) high commitment attenuated positive associations between high discrimination and high prevalence and/or frequency of IPV perpetration; and (3) high internalized homophobia was related to low commitment, which in turn was related to high prevalence and/or frequency of IPV perpetration. Collectively, our study identified commitment as both a moderator and mediator in associations from sexual minority stressors to same-sex IPV. Further, the roles of commitment (i.e., moderator or mediator) depend on whether the focal sexual minority stressors are distal and more intermittent (i.e., heterosexist discrimination) or proximal and more constant (i.e., internalized homophobia).

Abnormal transitions of dynamic functional connectivity states in bipolar disorder: A whole-brain resting-state fMRI study

BACKGROUND

Dynamic functional connectivity (dFC) based on resting-state fMRI has attracted interest in the field of bipolar disorder (BD), because dFC can better capture the evolving processes of emotion and cognition, which are typically impaired in BD. However, previous dFC studies of BD have typically focused on specific seed brain regions or specific functional brain networks, and they have ignored global dynamic information interaction in the whole brain. This study is aimed to reveal aberrant and interpretable whole-brain dFC patterns of BD.

METHODS

The resting-state fMRI data collected from 35 euthymic BD patients and 30 healthy people. We developed a new dFC inference pipeline, including the sliding-window method, k-means clustering, a new permutation with zero-inflated Poisson regression method, and a similarity analysis for interpretable states, to examine the different patterns of dFC states between BD patients and healthy participants.

RESULTS

BD patients had significantly more frequent transitions between two specific dFC states, which were respectively close to high-level cognitive networks and low-level sensory networks, than healthy controls (p < 0.05, FDR).

LIMITATIONS

The size of samples and other BD types need to be expanded to validate the results of this study. Possible confounding effect of medication.

CONCLUSIONS

This study detected aberrant dFC pattern of BD, which indicated the increased lability of the processes of cognition and emotion in BD, and this finding could improve our understanding of the neuropathological mechanism of BD.

Development and Validation of Psychological Contract Scale for Hospital Pharmacists

Objective

To set up a psychological contract scale for hospital pharmacists to strengthen the management of pharmacists and improve the occupational health of pharmacists.

Methods

A psychological contract scale for hospital pharmacists with structured questionnaires was designed according to the professional characteristics of hospital pharmacists and validated through the investigation of pharmacists in 77 public medical institutions in Zunyi, China, which were included through stratified random sampling. Kaiser-Meyer-Olkin (KMO) Measure of Sampling Adequacy and Bartlett’s Test of Sphericity were used to assess the suitability of the sample for factor analysis. Validity of the dimensions was investigated with exploratory factor analysis. The principal component analysis and varimax rotation methods were used to identify the factor structure. The internal consistency was assessed by the Cronbach’s alpha coefficient.

Results

The psychological contract scale for hospital pharmacists was composed of pharmacists’ perceptions regarding the hospital, pharmacists themselves, and government/society responsibility. The KMO values of the three perceptions were 0.957, 0.930 and 0.917, respectively, all greater than 0.6. The significance probability of the Bartlett spherical test was 0.000, indicating good structural validity. The Cronbach’s alpha coefficient and half coefficient of the responsibilities in three sub-scales were all greater than 0.6, indicating good internal reliability of the scale. The average scores of the pharmacist responsibility, the hospital responsibility and the government/society responsibility in the pharmacists’ perception were 5.42±0.637, 4.64±1.069 and 4.49±1.134, respectively. In the pharmacists’ perception, their own responsibility has been better fulfilled than those of hospitals and government/society.

Conclusion

The psychological contract scale for hospital pharmacists can be a useful tool to evaluate the psychological contract of hospital pharmacists for research and occupational health assessments and management in the area of hospital pharmacy.
