The factor structure of the Revised Illness Perception Questionnaire (IPQ-R) in end-stage renal disease patients

The purpose of this study was to examine the factor structure of the Revised Illness Perceptions Questionnaire (IPQ-R) in a sample of 374 end-stage renal disease (ESRD) patients. A confirmatory factor analysis of the IPQ-R, including the illness identity subscale, demonstrated adequate model fit for the factor structure as originally defined by (Moss-Morris, R., Weinman, J., Petrie, K. J., Horne, R., Cameron, L. D., & Buick, D. (2002). The revised Illness Perception Questionnaire (IPQ-R). Psychology & Health, 17 (1), 1-16.) Modifying the a-priori IPQ-R factor structure by removing two items with low factor loadings and specifying a path between personal control and item 23 had marginally better fit. A separate exploratory factor analysis of the causal items indicated three factors relating to Biological, Psychological and Behavioural causes. These findings provide evidence towards the validity and reliability of the IPQ-R as a suitable measure of illness perceptions in the context of ESRD.     

What behaviours do students consider academically dishonest? Findings from a survey of Canadian undergraduate students

This paper identifies those behaviours that students perceive to be academically dishonest and sheds light on several demographic, academic and situational factors that predict students’ perceptions of academic dishonesty. Data for this investigation were obtained through self-administered questionnaires from a sample of 321 undergraduate students attending university in a western Canadian city during the academic year 2007–2008. There was a high extent of leniency in students’ definitions of what behaviours constitute academic dishonesty, particularly for situations involving plagiarism and helping somebody else cheat. Sex, importance of academic ethic, strength of academic ability, deep learning strategy, and frequency of witnessing peers cheat made unique contributions to the prediction of students’ perceptions of dishonesty. Implications of these findings for institutional interventions are discussed.     

A systematic review and meta-analysis of the Brief Illness Perception Questionnaire

Objective: This paper aims to systematically review the use and performance of the Brief Illness Perception Questionnaire (Brief IPQ).

Design: Electronic databases were searched for papers administering the Brief IPQ published in peer-reviewed journals. Data were extracted from the results for meta-analysis.

Main outcome measures: Use by illness population, country, language and study design. The questionnaire’s concurrent validity, predictive validity, sensitivity to change, discriminant validity and mean scores for different populations were summarised.

Results: The review included 188 papers. The Brief IPQ has been administered to patients from age 8 to over 80, with a wide range of illnesses, in 26 languages from 36 countries. Pooled correlations between illness perceptions and depression, anxiety, blood glucose levels and quality of life were consistent with previous research and theory (range .25–.49 for consequences, identity and emotional representations; ?.12 to ?.27 for personal control). All items were able to predict some outcomes up to one-year follow-up. Each subscale demonstrated sensitivity to change after intervention in randomised controlled trials with the personal control and causal items showing most frequent change.

Conclusions: The Brief IPQ is widely used and has good psychometric properties. More studies should include and analyse the causal item.     

Sex differences in scanning faces: Does attention to the eyes explain female superiority in facial expression recognition?

Previous meta-analyses support a female advantage in decoding non-verbal emotion (Hall, 1978, 1984), yet the mechanisms underlying this advantage are not understood. The present study examined whether the female advantage is related to greater female attention to the eyes. Eye-tracking techniques were used to measure attention to the eyes in 19 males and 20 females during a facial expression recognition task. Women were faster and more accurate in their expression recognition compared with men, and women looked more at the eyes than men. Positive relationships were observed between dwell time and number of fixations to the eyes and both accuracy of facial expression recognition and speed of facial expression recognition. These results support the hypothesis that the female advantage in facial expression recognition is related to greater female attention to the eyes.     

Lecturers' faces fatigue their students: Face identity aftereffects for dynamic and static faces

Face adaptation has been used as a tool to probe our representations for facial identity. It has also been claimed to play a functional role in face processing, perhaps calibrating the visual system towards encountered faces. However, for this to be so, face aftereffects must be observable following adaptation to ecologically valid moving stimuli, not just after prolonged viewing of static images. We adapted our participants to videos, static image sequences or single images of the faces of lecturers who were personally familiar to them. All three stimulus types produced significant, and equivalent, face identity aftereffects, demonstrating that aftereffects are not confined to static images but can occur after exposure to more naturalistic stimuli. It is also further evidence against explanations of face adaptation effects solely in terms of low-level visual processing.     

Physiologic Response,Perceptual Threshold,and Rorschach Test Anxiety Indices

This study examined the sensitivity and specificity of the Trauma Symptom Inventory (TSI, Briere, 1995), a self-report measure of psychological sequelae of potentially traumatic events, to malingering. An optimal cutting score for a validity scale—Atypical Responding (ATR)—designed to identify exaggeration or other unusual response sets was developed in an analogue sample of 155 college students and subsequently applied to TSI profiles from several samples of patients with various psychiatric disorders. Use of a cross-validated T-score cutoff of 61 and below on the ATR scale produced good sensitivity (81%) and specificity (92%) rates in the analogue sample. Participants in the analogue sample who reported a history of traumatic experiences were no more able to successfully malinger trauma, symptoms than were participants without such histories. Furthermore, false-positive rates in the clinical samples were generally low, suggesting that relatively few genuinely symptomatic individuals would be misclassified as malingering.     

Altruism in social networks: Evidence for a ‘kinship premium’

Why and under what conditions are individuals altruistic to family and friends in their social networks? Evolutionary psychology suggests that such behaviour is primarily the product of adaptations for kin‐ and reciprocal altruism, dependent on the degree of genetic relatedness and exchange of benefits, respectively. For this reason, individuals are expected to be more altruistic to family members than to friends: whereas family members can be the recipients of kin and reciprocal altruism, friends can be the recipients of reciprocal altruism only. However, there is a question about how the effect of kinship is implemented at the proximate psychological level. One possibility is that kinship contributes to some general measure of relationship quality (such as ‘emotional closeness’), which in turn explains altruism. Another possibility is that the effect of kinship is independent of relationship quality. The present study tests between these two possibilities. Participants (N= 111) completed a self‐report questionnaire about their willingness to be altruistic, and their emotional closeness, to 12 family members and friends at different positions in their extended social networks. As expected, altruism was greater for family than friends, and greater for more central layers of the network. Crucially, the results showed that kinship made a significant unique contribution to altruism, even when controlling for the effects of emotional closeness. Thus, participants were more altruistic towards kin than would be expected if altruism was dependent on emotional closeness alone – a phenomenon we label a ‘kinship premium’. These results have implications for the ongoing debate about the extent to which kin relations and friendships are distinct kinds of social relationships, and how to measure the ‘strength of ties’ in social networks.     

Symptom modelling can be influenced by psychiatric categories: choices for research domain criteria (RDoC)

Psychiatric researchers typically assume that the modelling of psychiatric symptoms is not influenced by psychiatric categories; symptoms are modelled and then grouped into a psychiatric category. I highlight this primarily through analysing research domain criteria (RDoC). RDoC’s importance makes it worth scrutinizing, and this assessment also serves as a case study with relevance for other areas of psychiatry. RDoC takes inadequacies of existing psychiatric categories as holding back causal investigation. Consequently, RDoC aims to circumnavigate existing psychiatric categories by directly investigating the causal basis of symptoms. The unique methodological approach of RDoC exploits the supposed lack of influence of psychiatric categories on symptom modelling, taking psychiatric symptoms as the same regardless of which psychiatric category is employed or if no psychiatric category is employed. But this supposition is not always true. I will show how psychiatric categories can influence symptom modelling, whereby identical behaviours can be considered as different symptoms based on an individual’s psychiatric diagnosis. If the modelling of symptoms is influenced by psychiatric categories, then psychiatric categories will still play a role, a situation which RDoC researchers explicitly aim to avoid. I discuss four ways RDoC could address this issue. This issue also has important implications for factor analysis, cluster analysis, modifying psychiatric categories, and symptom based approaches.     

Cancer survivors’ and partners’ key concerns and quality of life

Objective: Understanding the concerns of cancer survivors is essential for effective interventions. This study was designed to identify the primary concerns of dyads coping with cancer, how concerns differed by role and sex, and whether concerns expressed during counselling were associated with survivors’ psychosocial well-being and adjustment.

Design: Forty-three dyads with breast and prostate cancer (N = 86 participants) were enrolled in an interpersonal telephone counselling intervention. Audio recordings of 228 counselling sessions were transcribed and content analysed qualitatively to identify major themes and key concerns. A total of three 30-min sessions were coded for each study participant. Quantitative data and statistical analyses were used to predict changes in survivors’ quality of life.

Main Outcome Measures: Participants completed psychosocial well-being measures (depression, positive/negative affect, and relationship satisfaction), pre- and post-counselling.

Results: Survivors’ concerns focused on cancer- and treatment-related issues, whereas partners’ concerns centred on the well-being of their spouse/partner with cancer, and what they were doing to help their loved one cope with his/her illness. Key concerns for all consisted of relationship maintenance and communication issues. Further, discussion of these concerns was predictive of significant improvements in adjustment post-counselling for women with breast cancer.

Conclusion: Discussion of interpersonal concerns may play a more important role in the well-being of women, than men, coping with cancer.
