Quantile Mediation Models: A Comparison of Methods for Assessing Mediation Across the Outcome Distribution

Recent introduction of quantile regression methods to analysis of epidemiologic data suggests that traditional mean regression approaches may not suffice for some health outcomes such as Body Mass Index (BMI). In the same vein, the traditional mean-based approach to mediation modeling may not be sufficient to capture the potentially different mediating effects of behavioral interventions across the outcome distribution. By combining methods for estimating conditional quantiles with traditional mediation modeling techniques, mediation effects can be estimated for any quantile of the outcome distribution (so-called quantile mediation effects). Estimation and inference techniques for quantile mediation effects are compared through simulation studies, and recommendations are given. The quantile mediation methods are further compared with the traditional mean-based regression approaches to mediation analysis through analysis of data from Healthy Places, a trial that is examining the effects of the community–built environment on resident obesity risk. We found the magnitudes of indirect (mediating) effects of walkability on BMI and waist circumference were substantially larger for the upper quantiles compared with the median or mean. Results suggest that restricting the examination of mediation to the mean of the outcome distribution provides an incomplete picture of proposed mediating mechanisms and in some cases may miss important mediational relationships to outcomes.     

Transference,triangles and trajectories

In this article the author addresses the issue of the need to lessen the likelihood of a regressive transference neurosis in short-term therapy. He examines the role that active interpretation of the transference can have in shaping the transference so that it remains at the level of the transference that is ubiquitous. He explores the relationship between such an active interpretative approach and the need for the therapist to be empathic and sensitive to the patient and to allow space for a patient's independent discoveries. The author describes the role of the Central Therapeutic Focus, as a constellation of the Triangles of Insight, in guiding the therapist to select those manifestations of the transference to interpret, and in enabling the therapist to retain a stance that is sensitive and empathic. The Central Therapeutic Focus is contrasted with the concept of the Central Issue, and with the latter's more specific attention to the contribution that it makes to the therapist's communication of their empathic understanding of the patient's difficulties. The nature of the relationship between the therapist and the patient in short-term therapy is explored further and the connections between companionable interaction, ego-relatedness and the matrix of the transference are outlined. The author proceeds to consider the nature of the process of working through in short-term therapy and of the need to attend to the patient's external world as the place in which this can occur. The contribution of the Central Therapeutic Focus in shaping the trajectory through which the patient and therapist attend to the external world is examined. This in turn is linked to the identification of a patient's ordinary solution to their problem as a means of resolving their Dilemma. The article concludes with a case example that illustrates these themes.     

Relationship Patterns and Role of Religion in Elderly Couples with Chronic Illness

ABSTRACT

This study was designed to explore the various relationship patterns and the role religion plays as a coping resource for elderly couples in which at least one spouse has a chronic illness. Elderly couples were interviewed and also completed marital satisfaction and couple communication inventories. Five different relationship patterns emerged from the data: active couples, short-term caregivinjg couples, long-term caregiving couples, survival couples, and live-in caregiver couples. Various aspects of religion emerged as an important coping resource among the different relationship patterns. Ideas and questions for research and practice, generated by the study, are presented.     

Predicting Romantic Interest at Zero Acquaintance: Evidence of Sex Differences in Trait Perception but Not in Predictors of Interest

We evaluated five competing hypotheses about what predicts romantic interest. Through a half‐block quasi‐experimental design, a large sample of young adults (i.e. responders; n = 335) viewed videos of opposite‐sex persons (i.e. targets) talking about themselves, and responders rated the targets' traits and their romantic interest in the target. We tested whether similarity, dissimilarity or overall trait levels on mate value, physical attractiveness, life history strategy and the Big Five personality factors predicted romantic interest at zero acquaintance and whether sex acted as a moderator. We tested the responders' individual perception of the targets' traits, in addition to the targets' own self‐reported trait levels and a consensus rating of the targets made by the responders. We used polynomial regression with response surface analysis within multilevel modelling to test support for each of the hypotheses. Results suggest a large sex difference in trait perception; when women rated men, they agreed in their perception more often than when men rated women. However, as a predictor of romantic interest, there were no sex differences. Only the responders' perception of the targets' physical attractiveness predicted romantic interest; specifically, responders' who rated the targets' physical attractiveness as higher than themselves reported more romantic interest.

Alternative Lens Model Equations for Dichotomous Judgments about Dichotomous Criteria

The Brunswik lens model typically represents a judge's accuracy using parameters derived from linear regression. This is not optimal if the judgment or the ecological criterion is dichotomous. Alternative approaches, modeling dichotomies using logistic regression, or linearizing judgments with confidence ratings, have not been compared with the same data. Four techniques for deriving lens model equation parameters were compared: (i) linear and (ii) logistic regression applied to dichotomous patient outcomes and judgments; (iii) linear regression with confidence‐adjusted judgments but dichotomous patient outcomes; and (iv) a hybrid with a linear model of the confidence‐adjusted judgments and a logistic model of the patient outcomes. Judgment accuracy (r_a) was slightly higher with confidence adjustment of the categorical judgments. The logistic lens model accounted for a higher proportion of r_a than the linear lens model; the confident‐linear and hybrid lens models were intermediate. For up to a quarter of participants, different methods identified different cues as most important. Display condition differences in achievement r_a and in lens model components are similar with all lens model methods. Each of the three alternative lens model equation methods improves on the linear lens model equation's decomposition of the accuracy of dichotomous judgments. Confidence adjustment improves achievement although it requires additional work from the subjects. The logistic lens model equation explains the highest proportion of achievement, but with a small stimulus set, it is more vulnerable to cue intercorrelations than either the linear or the confident linear lens model equation.

Measuring logistics performance of OECD countries via fuzzy linear regression

In logistics, performance measurement has been considered as a key competency to acquire world class performance. In light of this, we presented a robust methodology to establish an analysis framework for measuring logistics performance. The proposed hybrid methodology is a combination of criteria importance through intercritera correlation (CRITIC), simple additive weighting (SAW), and Peters' fuzzy regression methods. To the best of our knowledge, country‐based logistics performance is seldom studied in the literature. Therefore, we measured the logistics performance of Organization for Economic Cooperation and Development (OECD) countries using the devised model based on the data of Logistics Performance Index 2014 provided by the World Bank. The introduced methodology, which is suitable to model imprecise relationships among system parameters, appears to be a practical alternative approach for the assessment of logistics performance. It should be noted that the evaluation framework presented in this paper is not confined to performance measurement case and can also be exploited in addressing other multiple criteria decision‐making problems incorporating uncertainty.

The utility and accuracy of oral reading fluency score types in predicting reading comprehension

This study used data from the Dynamic Indicators of Basic Early Literacy Skills (DIBELS; Good & Kaminski, 2002) oral reading fluency (ORF) probes to examine variation among different ORF score types (i.e., the median of three passages, the mean of all three passages, the mean of passages 2 and 3, and the score from passage 3) in predicting reading comprehension as a function of student reading fluency level and to compare the screening accuracy of these score types in predicting student reading comprehension. The results revealed that the relation between oral reading fluency and reading comprehension varied as a function of students' oral reading fluency and that different score types had varying predictive validity for year-end reading comprehension. The mean of all three passages demonstrated a marginally better balance in screening efficiency from September to December of grade one (especially for low-performing students), whereas in grades two and three, the median score was the best predictor. Furthermore, across all grades, increasing reading rates were observed for the three administered passages within an assessment period. The observed patterns mimicked previous experimental studies (Francis et al., 2008; Jenkins, Graff, & Miglioretti, 2009), suggesting that practice effects are an important consideration in the administration of multiple passages assessing oral reading fluency.     

Silicon in ‘pure gold’? Theoretical contributions and observations on teleanalysis by videoconference

Ideas about psychoanalysis via videoconference—videoconference teleanalysis (VT)—are presented with the general understanding that these settings produce a twofold split between various degrees of recognition/negativisation of the absence of the other, on one hand, and the expectation of physical co‐presence, on the other. This split has been put forward as dismantling the here, now, with me pre‐reflexive unity of the analytic experience. This article suggests that both members of the analytic dyad will seek to reappropriate the experience through a forced ego integration that interferes with accessing states of unintegration in the analytic treatment and produces subtle alterations to symbolisation work. The effort to overcome this condition is illustrated with clinical vignettes and therapists’ comments about feelings of inauthenticity and discontent when trying to sustain evenly‐suspended attention, as well as in the perception of a form of flattening of the alive nature of speech. However, this is not a constant for all VT, and mutual understanding can be an important mitigating feature. The focus of the discussion should be on the capacity of the analytic dyad to overcome such a split and not on a direct extrapolation of the perceptual limitations of VT to possible effects on transference / countertransference.     

Concurrent and longitudinal dyadic polynomial regression analyses of Big Five traits and relationship satisfaction: Does similarity matter?

Being with a well-matched partner seems essential for a happy relationship. However, past research on personality similarity in couples has reported inconsistent findings. The current study employs a dyadic polynomial regression approach to take into account linear and curvilinear associations between similarity and satisfaction. The concurrent results based on data of 237 couples suggest that beyond actor effects for neuroticism, agreeableness, and conscientiousness and partner effects for agreeableness, similarity plays a negligible role for relationship satisfaction. Longitudinally, two similarity effects emerged. First, if partners reported dissimilar neuroticism levels, male partner reported lower relationship satisfaction. Second, if both partners reported modest levels in openness, female partners reported higher relationship satisfaction. Implications for couples are discussed.
