Fatigue, cognitive functioning and psychological distress in Marfan syndrome, a pilot study

Marfan patients report fatigue as a major subjective complaint. We found no studies exploring the subject. The aim of this study was in a strictly defined Marfan population to assess self-reported fatigue, cognitive functions and psychological distress, correlations among them and correlations to visual acuity, joint hypermobility and use of beta-blockers. Sixteen subjects aged 18 - 30 years, fulfilling the Gent criteria, were assessed with the Fatigue Severity Scale, Fatigue Questionnaire, a comprehensive battery of neuropsychological tests and the General Health Questionnaire (GHQ). Self-reported fatigue was comparable with fatigue reported in other severe chronic diseases and disabilities, and was primarily in the mental/psychological domain. Psychological distress was higher than expected compared with the population at large. All neuropsychological test results were within the normal range, except for tests of visuo-motor coordination and speed of information processing. There was a significant inverse correlation between Fatigue Questionnaire ratings and some neuropsychological tests. Fatigue seems to be a serious problem for persons with Marfan syndrome and seems related to some areas of cognitive functioning. We found no overall impairment in cognitive functioning, but slightly reduced speed of information processing. Reduced visuo-motor coordination could be explained by impaired visual acuity.     

Mental body distance comparison: A tool for assessing clinical disturbances in visual body image

Despite numerous body size estimation studies, it cannot be concluded that the disturbance of body image in anorexia nervosa (AN) is specifically one of the visual body images.We adopted a visual imagery method, the Distance Comparison task, to enable across-population testing of differences in visual body image with respect to shape. Participants were asked to mentally scan across two body widths (e.g. hips and shoulders) and to decide as quickly as possible which one was longer or shorter. If the mental representation accessed to make such comparisons is visual, an inverse relation would be expected between RT and distance difference on the body to be judged (i.e. actual difference in size between the two body widths), with accuracy increasing with increasing distance difference. Females with high body shape concern (scoring high on the Body Shape Questionnaire: BSQ, n = 23) were compared to females with low body shape concern (scoring low on the BSQ, n = 19).RT and distance differences on the body demonstrated standard distance differences effects: RT increased and accuracy decreased with decreasing distance differences on the body. Groups differed with respect to accuracy, in that females high on body shape concern were significantly less accurate than females low on body shape concern when making evaluations involving small (?9 cm) differences, which implies a less appropriate visual image of the own body in the former group. With respect to the relation between RT and body distance difference, on the other hand, there were no differences between groups. We concluded that evaluations of own body size employ visual imagery and that the distance comparison task holds promise for the assessment of visual disturbances in body image in clinical populations.     

Bayesian model selection of informative hypotheses for repeated measurements

When analyzing repeated measurements data, researchers often have expectations about the relations between the measurement means. The expectations can often be formalized using equality and inequality constraints between (i) the measurement means over time, (ii) the measurement means between groups, (iii) the means adjusted for time-invariant covariates, and (iv) the means adjusted for time-varying covariates. The result is a set of informative hypotheses. In this paper, the Bayes factor is used to determine which hypothesis receives most support from the data. A pivotal element in the Bayesian framework is the specification of the prior. To avoid subjective prior specification, training data in combination with restrictions on the measurement means are used to obtain so-called constrained posterior priors. A simulation study and an empirical example from developmental psychology show that this prior results in Bayes factors with desirable properties.     

Exerting Self‐Control ≠ Sacrificing Pleasure

Self‐control is a prominent topic in consumer research, where it is often conceptualized as the abstinence from hedonic consumption. We examine whether this conceptualization accurately captures consumers’ experiences of self‐control conflicts/failures in light of seminal self‐control theories in economics and psychology. Rejecting that notion, we argue that self‐control failures are choices in violation of superordinate long‐term goals accompanied by anticipated regret, rather than choices of hedonic over utilitarian consumption. This conceptualization has important methodological, theoretical, and practical implications. Methodologically, it highlights the need for experimental paradigms with higher construct validity. Theoretically, it helps elucidate how self‐control is distinct from impatience and self‐regulation. Practically, it provides a rich set of implications for deducing interventions on the individual and public policy level to help consumers exert self‐control.

The architecture of high status among Finnish youth

We tested the construct validity of a two‐dimensional model of high status, consisting of social acceptance and perceived popularity (hereafter, acceptance and popularity) among Finnish children and adolescents. In addition, we investigated the correlates of the two forms of high status, as well as their relations to resource control. Participants were 563 boys and girls in grades four and eight, that is, aged 10–11 and 14–15. CFA and SEM models supported the hypothesis of acceptance and popularity representing distinct, yet associated constructs that have partly different correlates. Acceptance and popularity were most closely connected among grade four students, particularly among boys. Prosocial behaviour was associated with acceptance, whereas peer‐valued characteristics (physical attractiveness, athletic ability) and aggression were related especially to popularity. Popularity, but not acceptance, was positively related to resource control.
