Body satisfaction, eating disorders and suicide ideation in an Internet sample of self-harmers reporting and not reporting childhood sexual abuse

This study examined differences between self-harmers who had and who had not been sexually abused in childhood with regards to other risk factors and associated behaviours commonly identified in the research literature as being related to self-harm. Participants (N = 113, mean age = 19.92 years) were recruited via self-harm Internet discussion groups and message boards, and completed a web questionnaire assessing measures of body satisfaction, eating disorders, childhood trauma and suicide ideation. Self-harmers who reported a history of childhood sexual abuse scored higher on measures of body dissatisfaction, eating disorders, suicide ideation, physical abuse, physical neglect, emotional abuse and emotional neglect. These findings implicate sexual abuse as a powerful traumatic event that can have severe repercussions on an individual, not only in terms of self-harming behaviour but also in terms of developing a wide range of maladaptive behaviours in conjunction with self-harm.     

Qualitative Health Research and the IRB: Answering the “So What?” with Qualitative Inquiry

Qualitative inquiry is increasingly used to foster change in health policy and practice. Research ethics committees often misunderstand qualitative inquiry, assuming its design can be judged by criteria of quantitative science. Traditional health research uses scientific realist standards as a means-to-an-end, answering the question “So what?” to support the advancement of practice and policy. In contrast, qualitative inquiry often draws on constructivist paradigms, generating knowledge either as an end-in-itself or as a means to foster change. When reviewers inappropriately judge qualitative inquiry, it restricts the ways health phenomena can be understood. Qualitative inquiry is necessary because it enables an understanding not possible within scientific explanation. When such research illuminates, it can also shed light onto the “So what?” In order to ensure an appraisal of qualitative inquiry congruent with its paradigmatic premises, we suggest the “Illumination Test,” met when findings foster rich understanding of phenomena, resulting in a reflective “aha!”     

Decision criteria do not shift: Reply to Treisman

Recently, we argued that the detection criterion representation of decision-making biases, embedded within the theory of signal detection, is empirically testable and has, in fact, been falsified by empirical results from visual discrimination experiments. Treisman (2002) attempts to show that there is an alternative interpretation of our results that could explain them without dropping the detection criterion construct. In lieu of attempting to fit the data with a model, however, he gives two kinds of theoretical examples, both involving manipulations of the spacing of criteria on a decision axis. The first example correctly predicts that the bias estimate we developed will be zero but does so by assuming zero spacing between some criteria (some rating responses are never used). We did not observe zero spacing between any criteria and did not perform any analyses on responses that never occurred. Moreover, this example does not explain why the upper-bound bias estimates that we obtained by combining results from two criteria placements were also trivially small. His second example predicts that the bias should have been detectable with sufficiently large sample sizes. In our experiments, the sample sizes were, in fact, quite large, large enough for the results to be consistent in 18 different experimental conditions. Finally, all of Treisman’s criteria placement examples also fail to explain the pronounced effects of base rates on the shapes of the rating ROC curves, and his suggestion that there are problems of logical interpretation with our proposed distribution model ignores the predictions of large classes of alternatives to detection theory, including the dynamic models of perception.     

‘Hijab envy’: the visible angst of immigrant Christians in a pluralist Canada

This article explores the predilection of Christians of immigrant background to perceive themselves as a disadvantaged group in the new reality of Canada’s growing religious diversity. The present inquiry challenges loss as the definitive emotional register for Christian engagement with Canada’s new religious minorities, demonstrating that religious minorities have elicited begrudging admiration and envy from their Christian counterparts. This inquiry insists that contemporary Canada, not ‘Christian Canada’, is the most important frame for understanding the perceptions and predilections of the Christians in this study. It argues that pluralist ideals, the policy instruments, and social practices that carry these ideals and the cultural forums that display and debate these ideals shape not only the ‘attitudes’ of young Christians, but also the regimes of visibility in which and from which they operate. While scholars impute an increasing visibility to religion, this article demonstrates that the array of affects between viewer and viewed are highly variable and context specific.     

Visual perceptual load induces inattentional deafness

In this article, we establish a new phenomenon of "inattentional deafness" and highlight the level of load on visual attention as a critical determinant of this phenomenon. In three experiments, we modified an inattentional blindness paradigm to assess inattentional deafness. Participants made either a low- or high-load visual discrimination concerning a cross shape (respectively, a discrimination of line color or of line length with a subtle length difference). A brief pure tone was presented simultaneously with the visual task display on a final trial. Failures to notice the presence of this tone (i.e., inattentional deafness) reached a rate of 79% in the high-visual-load condition, significantly more than in the low-load condition. These findings establish the phenomenon of inattentional deafness under visual load, thereby extending the load theory of attention (e.g., Lavie, Journal of Experimental Psychology. Human Perception and Performance, 25, 596-616, 1995) to address the cross-modal effects of visual perceptual load.     

Illness representations in patients with multimorbid long-term conditions: qualitative study

Most research on illness representations explores how patients view single conditions, but many patients report more than one long-term condition (known as multimorbidity). It is not known how multimorbidity impacts on patient illness representations. This exploratory qualitative study examined patients' representations of multimorbid long-term conditions and sought to assess how models of illness representation might need modification in the presence of multimorbidity. We explored two major issues: (1) the impact of multimorbidity on patient representations of their individual conditions and (2) the representation of multimorbidity itself. Twenty eight adults with at least two long-term conditions (mean of 4) were interviewed. The presence of multimorbidity impacted on patient illness representations in relation to the dimensions of identity, perceived cause, coherence and consequences. Representations of multimorbidity itself concerned representations of the burden of medication and perceived priorities among conditions and synergies and antagonisms between conditions and their management. The results have implications for the measurement of multimorbidity (through scales such as the Illness Perception Questionnaire) and the use of illness representations in the design and delivery of interventions to improve health behaviour and outcomes of patients with multiple long-term conditions.
