We examined whether romantic relationship satisfaction would serve as a link between early and later stressors which in turn would influence the thyroid function index (TFI), an indicator of physiological stress response. Using the framework of genetic susceptibility theory combined with hypotheses derived from the vulnerability-stress-adaptation and stress-generation models, we tested whether ...

Dr. Pearl invites researchers to justify their use of principal stratification. This comment explains how the use of principal stratification simplified a complex mediational problem encountered when evaluating a smoking cessation intervention's effect on reducing smoking withdrawal symptoms.

OBJECTIVE This research examined why smokers receiving combination medication for smoking cessation are more likely to quit smoking than are those who receive either single agent (monotherapy) or placebo. METHOD Data were collected from 1,504 current smokers (58.2% women, 83.9% White; mean age = 44.67 years, SD = 11.08) participating in a cessation clinical trial who were randomized to 1 of 6...

Background Insecure attachment is a precursor and correlate of borderline personality disorder. According to the mentalization-based theory of borderline personality disorder, the presence of insecure attachment derails the development of the capacity to mentalize, potentially resulting in borderline pathology. While one prior study found support for this notion in adolescents, it neglected a f...

In this paper, we present a theoretical model and an empirical review linking disorganized attachment with New Age spiritual beliefs and activities via a proposed mediator; the propensity to enter altered states of consciousness (absorption/dissociation). Utilizing a prospective longitudinal design (N = 62), an empirical test of the mediational model is also provided for illustrational purposes...

The authors propose and test a mediational model linking the experience of retirement with marital satisfaction. The experience of retirement (financial strain, time structure, a sense of purposefulness, and interpersonal contacts) is held to predict marital satisfaction indirectly through its sequential effects on context-specific well-being (retirement-specific satisfaction with health, activ...

The authors propose that experiments that utilize mediational analyses as suggested by R. M. Baron and D. A. Kenny (1986) are overused and sometimes improperly held up as necessary for a good social psychological paper. The authors argue that when it is easy to manipulate and measure a proposed psychological process that a series of experiments that demonstrates the proposed causal chain is sup...

Applied researchers often include mediation effects in applications of advanced methods such as latent variable models and linear growth curve models. Guidance on how to estimate statistical power to detect mediation for these models has not yet been addressed in the literature. We describe a general framework for power analyses for complex mediational models. The approach is based on the well ...

Research on computer-based adaptive learning environments has shown exemplary growth. Although the mechanisms of effective adaptive instruction are unraveled systematically, little is known about the relative effect of learners’ perceptions of adaptivity in adaptive learning environments. As previous research has demonstrated that the learners’ view towards a learning environment strongly influ...
