Latent Change Score Modeling

An image of drowned Syrian toddler, Aylan Kurdi, was popularly shared through social media and this promoted a surge of solidarity with Syrian refugees in September 2015. However, this response was not sustained. We explore the role of social media engagement in the emergence of solidarity and its decline (compassion fade). We collected data when sympathy for refugees was peaking (September 2015), and 1 year later. Latent change score modeling ( N = 237) showed that engagement with the image through social media allowed people to form a pro-refugee group consciousness that acted as the proximal predictor of solidarity. However, reductions in the same factors explain the reduced commitment 1 year later. Distress predicted the reductions in social media engagement. The results support the power of social media to ignite world-changing action, but caution that online engagement may dissipate in the face of ongoing challenges.

Turnover Cognitions

Theory and practice suggest workplace incivility is progressive and dynamic. To date, however, workplace incivility has been assessed as a between-person phenomenon by asking employees to summarize their exposure to incivility over some specific period (e.g., 1 year or 5 years). Consequently, little is known about the time-varying and progressive aspects of workplace incivility as suggested by both the referent literature and experience. Within the context of employee burnout and withdrawal, we developed a novel, dynamic mediated model of workplace incivility change and tested specific predictions about its time-sequential effects. Latent change score modeling of weekly survey data from 131 employees indicates that incivility change uniquely affects subsequent changes in burnout, which, in turn, lead to subsequent changes in turnover cognitions. We also explore whether this dynamic mediated effect varies across time and individuals.

Commitment Theory

Rooted in commitment theory, this study examines dedication, perceived investments, and felt constraint, three unique aspects of commitment, in midlife using data gathered from a sample of 224 adults surveyed at ages 43 and 50 years. Positive and negative dimensions of couple relations (partner supportiveness and the extent to which one’s partner is demanding and critical, referred to as strain) assessed longitudinally and midlife-specific circumstances, including being in a first marriage or remarriage and parental and empty nest status, were examined as predictors of commitment at age 50. Latent change score modeling revealed partner support and strain as robust predictors of commitment. Higher levels of partner support at age 43 and a more gradual intraindividual decrease in support between ages 43 and 50 predicted higher dedication and perceived investments and less felt constraint at age 50. Higher age 43 levels of partner strain predicted more perceived investments and felt constraint at age 50, while a more rapid increase in strain predicted less dedication and more felt constraint. Being in a first or remarriage, being a parent, or having an empty nest did not predict commitment. These results highlight the importance of initial levels and changes in couple relations for shaping midlife commitment.

Before And After

Background: Major depressive disorder (MDD) is prevalent and has significant impact on individuals and society. Cognitive symptoms are frequent in MDD and insufficiently treated by antidepressant medications. Transcranial photobiomodulation (t-PBM) is a novel device therapy which shows promise as an antidepressant and pro-cognitive treatment. To date, despite the encouraging results, the optimal stimulation parameters of t-PBM to treat MDD are not established, and clinical studies are very heterogeneous in terms of these parameters. While the literature provides guidance on the appropriate fluence to achieve therapeutic results, little is known on the other parameters. Objective: To evaluate the relationship between different parameters and the antidepressant effect of t-PBM. Methods: We reviewed clinical studies on MDD and on depressive symptoms comorbid with other diseases. We calculated the standardized effect size of the change in symptoms severity before and after t-PBM and we performed a descriptive analysis of the reviewed papers. Results: The greatest effect sizes for the antidepressant effect were found in studies using pulse-wave t-PBM with high peak irradiance (but low average irradiance) over large skin surface. One well-designed and sufficiently powered, double-blind, sham-controlled trial indicated that t-PBM with low irradiance over a small skin surface is ineffective to treat depression. Conclusion: The use of t-PBM for Alzheimer’s disease and for dementia is still at its inception; these dosimetry lessons from the use of t-PBM for depression might serve as guidance.
