Psychological predictors for health-related quality of life and disability in persons with chronic obstructive pulmonary disease (COPD)

Objective: Individuals with chronic obstructive pulmonary disease (COPD) exhibit low physical and mental health-related quality of life (HRQL) and high susceptibility to disability. We investigated the influence of psychological factors on HRQL and disability in COPD individuals recruited from the general population. In line with Leventhal’s common sense model, we expected psychological factors to be associated with HRQL and disability even after controlling for medical status.

Methods: Individuals with COPD (n = 502; 59.7 years old; GOLD grades were I: 3%, II: 17%, III: 34%, IV: 46%) were assessed through an online survey administered via COPD patient organisations in Germany. Individuals filled in the Short Form Health Survey (SF-12), COPD Assessment Test, Patient Health Questionnaire (modules: GAD-2, PHQ-15, PHQ-9), Brief Illness Perception Questionnaire, a questionnaire that assesses causal illness attributions, and the internal illness-related locus of control scale of the ‘KKG questionnaire for the assessment of control beliefs about illness and health’. Multiple linear regressions were calculated.

Results: The investigated factors explained high variances (disability = 56%, physical HRQL = 28%, mental HRQL = 63%, p ≤ .001). Better mental health, more optimistic illness perceptions, attribution to psychological causes, and stronger internal locus of control were associated with lower disability and better HRQL. Comorbid somatic symptoms contributed to high disability and low quality of life.

Conclusion: Psychological factors, such as illness perception, attribution and internal locus of control, were associated with disability and HRQL. These factors should be considered when designing treatments for individuals with COPD, and adequate interventions should be provided to enhance illness understanding and self-management skills.     

Visual object imagery and autobiographical memory: Object Imagers are better at remembering their personal past

In the present study we examined whether higher levels of object imagery, a stable characteristic that reflects the ability and preference in generating pictorial mental images of objects, facilitate involuntary and voluntary retrieval of autobiographical memories (ABMs). Individuals with high (High-OI) and low (Low-OI) levels of object imagery were asked to perform an involuntary and a voluntary ABM task in the laboratory. Results showed that High-OI participants generated more involuntary and voluntary ABMs than Low-OI, with faster retrieval times. High-OI also reported more detailed memories compared to Low-OI and retrieved memories as visual images. Theoretical implications of these findings for research on voluntary and involuntary ABMs are discussed.     

Smelling matter

While the objects of olfaction are intuitively individuated by reference to the ordinary objects from which they arise, this intuition does not accurately capture the complex nature of smells. Smells are neither ordinary three-dimensional objects, nor Platonic vapors, nor odors. Rather, smells are the molecular structures of chemical compounds within odor plumes. Molecular Structure Theory is offered as an account of smells, which can explain the nature of the external object of olfactory perception, what we experience as olfactory objects, and what determines the olfactory quality of smells by which we can demarcate the spatiotemporal boundaries of smells.     

Attentional Predictors of 5‐month‐olds' Performance on a Looking A‐not‐B Task

In the first year of life, the ability to search for hidden objects is an indicator of object permanence and, when multiple locations are involved, executive function (i.e. inhibition, cognitive flexibility and working memory). The current study was designed to examine attentional predictors of search in 5‐month‐old infants (as measured by the looking A‐not‐B task), and whether levels of maternal education moderated the effect of the predictors. Specifically, in a separate task, the infants were shown a unique puppet, and we measured the percentage of time attending to the puppet, as well as the length of the longest look (i.e., peak fixation) directed towards the puppet. Across the entire sample (N = 390), the percentage of time attending to the puppet was positively related to performance on the visual A‐not‐B task. However, for infants whose mothers had not completed college, having a shorter peak looking time (after controlling for percentage of time) was also a predictor of visual A‐not‐B performance. The role of attention, peak fixation and maternal education in visual search is discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Modeling Martin-Löf type theory in categories

We present a model of Martin-Löf type theory that includes both dependent products and the identity type. It is based on the category of small categories, with cloven Grothendieck bifibrations used to model dependent types. The identity type is modeled by a path functor that seems to have independent interest from the point of view of homotopy theory. We briefly describe this modelʼs strengths and limitations.     

External and internal reality: The impact of the current socio‐economic crisis on the analytic dyad

This paper addresses the impact of the current economic crisis on the psychic functioning of the patient and the analyst, their relationship and collaboration. This intrusion of ‘external reality’ is multidimensional, and thus with multiple meanings. The critical role of the economic factor brings various dimensions of money into play, such as self‐preservation, power as well as aspects of psychosexual development. In addition, the crisis involves symbolic loss of basic ideals such as honesty and social responsibility. Patient and analyst are affected in similar and different ways in their respective roles as well as according to the specific intrapsychic functioning of each. Moreover, unique characteristics of the crisis often create a crisis in the analysis. In order to avoid deformation of the analytic relationship, the analytic dyad must examine and work through the multiple meanings of the crisis as well as the meaning of the impact of the crisis on the analytic relationship for both patient and analyst. This complex transference‐ countertransference interplay poses specific challenges to the analyst. After discussion of these issues, clinical material is presented that demonstrates how they appear in analytic practice today.
