How psychological resources mediate and perceived social support moderates the relationship between depressive symptoms and help-seeking intentions in college students

There is a high prevalence of depression among college students, which is linked to lower levels of help-seeking intentions. However, there has been a lack of research examining variables that may help explain this relationship. The present study aimed to address this gap by examining whether psychological resources (optimism and self-esteem) mediate the relationship between depressive symptoms and help-seeking intentions, and whether this relationship is moderated by perceived social support. Participants were 8121 college students (66% female) aged 17–25 years (M?=?20.42, SD?=?1.90), who completed the My World Survey Post-Second Level, a national survey on youth mental health. Linear regression analysis confirmed that depressive symptoms predicted lower informal help-seeking intentions. Moderated mediation indicated that social support moderated the direct relationship between depressive symptoms and informal help-seeking intentions and that optimism and self-esteem mediated this relationship, when gender was controlled for. Findings indicate that social support and psychological resources help further our understanding of the relationship between depressive symptoms and help-seeking in young people. Campaigns promoting help-seeking in college students should focus on the beneficial role of social support and on fostering optimism and self-esteem as facilitators of help-seeking intentions.     

Assessing Agreement between the K10 and MHI-5 Measures of Psychological Wellbeing

Responses to the Kessler Psychological Distress Scale (K10) and the Mental Health Index-5 (MHI-5) mental health subscale of the Medical Outcomes Study Short Form (SF-36) survey cover broadly similar constructs. The aim of this paper is to use the equipercentile method to produce a concordance between K10 and MHI-5 across the whole score distribution. Comparisons were made using survey data from the Australian Longitudinal Study on Women’s Health (ALSWH) and the Household, Income and Labour Dynamics in Australia (HILDA) survey, which used both the K10 and the MHI-5 measures at the same time for the same participants. Agreement was assessed with Bland-Altman plots. The differences between MHI-5 scores and transformed K10 scores were assessed with paired t-tests. For the ALSWH data there is good agreement between MHI-5 scores and scores equated from the K10. The mean of the differences is −0.15 with standard deviation 10.8. Using the ALSWH transformation on the HILDA data for different age groups and genders, the mean differences ranged from 0.43 to 3.38 with corresponding standard deviations of 11.1 to 9.9. The concordance table was very similar to one obtained by the more complicated item response theory method. The results suggest that longitudinal surveys of the same respondents that previously used MHI-5 could adopt the K10 (or vice versa) without loss of comparability.

     

The relationship of fear of falling and balance confidence with balance and dual tasking performance

According to traditional conceptualizations of the relationship between fear of falling and falls in older adults, fear of falling is considered to be predictive of falls because it leads to activity avoidance which, in turn, leads to de-conditioning that increases fall risk. The recent literature has begun to challenge such conceptualizations. Specifically, it has been argued that fear of falling and anxiety, in and of themselves, have a direct negative effect on balance. In this study we manipulated anxiety level by asking older research participants to walk either on the floor (low anxiety condition) or an elevated platform (high anxiety condition). Half the time participants carried a tray (dual tasking) and half the time they did not. Manipulation checks (involving heart rate, galvanic skin response, and self-reported anxiety measurement) confirmed that the experimental manipulation was successful in affecting anxiety level. The results demonstrate that the experimental manipulation (platform vs. floor) affected balance parameters and dual tasking performance with the platform condition resulting in a less stable gait. In addition, increased task demand (i.e., dual tasking) also had a negative effect on balance performance. Finally, the results demonstrate that the paper and pencil measures of fear can also predict balance performance (although the variance accounted for is small) even after controlling for medical risk factors for falling. Implications for models of fear of falling are discussed.     

Shape of prismatic dislocation loops in anisotropic α-Fe

Prismatic dislocation loops are the primary manifestation of radiation damage in crystals, and contribute to the phenomenon of radiation embrittlement. This undesirable effect, most serious for materials used in high-dose environments such as next-generation fission and future fusion reactors, results from the strong interaction between gliding dislocations, the carriers of plasticity, with the population of radiation-induced prismatic loops. Ferritic–martensitic steels, the most promising candidate materials for future high-dose applications, are based on iron and are known to become highly elastically-anisotropic at the high temperatures (>500°C) at which they must operate. In this article, we develop a novel modelling approach based on anisotropic elasticity theory to predict the shapes of prismatic loops in anisotropic crystals, paying particular attention to the technologically important case of α-iron. The results are compared with transmission electron microscope observations of the damage structure sustained by ultra-high-purity iron irradiated to a dose of approximately two displacements per atom.     

Change detection inflates confidence on a subsequent recognition task

A face viewed under good encoding conditions is more likely to be remembered than a face viewed under poor encoding conditions. In four experiments we investigated how encoding conditions affected confidence in recognising faces from line-ups. Participants performed a change detection task followed by a recognition task and then rated how confident they were in their recognition accuracy. In the first two experiments the same faces were repeated across trials. In the final two experiments novel faces were used on each trial. Target-present and target-absent line-ups were utilised. In each experiment participants had greater recognition confidence after change detection than after change blindness. The finding that change detection inflates confidence, even for inaccurate recognitions, indicates recognition certainty can be a product of perceived encoding conditions rather than authentic memory strength.     

The ‘Mysterious’ Thomas Manlevelt and Albert of Saxony

The essay casts doubt upon the view that Albert was criticizing or was dependent upon Thomas Manlevelt's logico-philosophical views, and counter argues that it is in fact Manlevelt who knows and cites Albert's views in his recently edited Porphyrian Questions, rather than vice versa. The argument for this conclusion proceeds in two stages. First, it is argued that the brief comment Albert makes about ‘conjunct descent’ (descensus copulatim) in treating the definition of merely confused supposition his Perutilis Logica does not conclusively show that Albert is criticizing the logico-philosophical view of Thomas Manlevelt, as the notion of ‘conjunct descent’ is already present in the work of Heytesbury. Hence, Albert may have been referring to him, since the unique contribution of Thomas Manlevelt to the definition of merely confused personal supposition appears completely unknown to Albert. Second, it is argued that the views in the Porphyrian Questions on the nature of the continuum, quantity, and dispositional vs. actual predication show the author's familiarity with the logico-philosophical views of Albert of Saxony, but not vice versa.     

A biopsychosocial formulation of pain communication

We present a detailed framework for understanding the numerous and complicated interactions among psychological and social determinants of pain through examination of the process of pain communication. The focus is on an improved understanding of immediate dyadic transactions during painful events in the context of broader social phenomena. Fine-grain consideration of social transactions during pain leads to an appreciation of sociobehavioral events affecting both suffering persons as well as caregivers. Our examination considers knowledge from a variety of perspectives, including clinical health psychology, social and developmental processes, evolutionary psychology, communication studies, and behavioral neuroscience.

“Experiences deemed religious”: Radical critique or temporary fix? Strategic ambiguity in Ann Taves’ Religious Experience Reconsidered

Ann Taves has written an interesting, lucid and informative book. In particular, the author’s suggested reformulation of religious studies as the study of “things deemed special” indicates a critical alternative to the dominant discourse. But such a reformulation implies that the ‘secular’ side of the mutually parasitic religion-secular binary also requires deconstruction. This in turn must surely lead to a critique of the representation of social psychology and related disciplines as ’natural science’, a representation which itself is already dependent on the wider, globalizing, ideological religion/secular binary, and its supernatural/natural correlate. The author’s ambiguous alternation between things deemed special and things deemed religious invites the discursive contours of ‘religion’ to re-enter through the back door, leaving the status quo substantially intact.
