Investigating the Factor Structure of the Kessler Psychological Distress Scale in Community and Clinical Samples of the Australian Population

The Kessler 10 Psychological Distress Scale (K10) is a brief dimensional scale designed to measure and monitor trends of psychological distress. Recently the scale has been utilised by general practitioners and clinicians to screen for common mental disorders and measure treatment outcomes. Despite the K10 demonstrating a sound one dimensional structure in the general population, the scale??s structure has yet to be comprehensively tested in clinical samples. The current study aimed to use confirmatory factor analysis to test three theoretical structure models of the K10 and one model for the K6 (a six item variant) in a sample from a tertiary referral clinic for mood and anxiety disorders and compare those results with a population sample from the Australian National Survey of Mental Health and Wellbeing. The results demonstrated that a two factor model with correlated latent factors representing depression and anxiety fit the clinical sample the best whilst a one factor model with correlated errors between several items fit the population sample the best. The results are discussed further in relation to scoring and interpreting the Kessler scales.     

Interreligious prayer between Christians and Muslims

This article distinguishes various ways in which the term ‘pray together’ might be understood and focuses on ‘interreligious prayer’, by which is meant here praying together using the same words with two religious groups united in heart and mind, rather than ‘multireligious prayer’, which refers to prayer in the presence of another religious group. The article argues that, in the early literature on the matter, there is a danger of conflating the two different types, and then shows that some Catholic communities, following the initiatives of Pope John Paul II, have reached a consensus that interreligious prayer is problematic, while multireligious prayer is not. The article goes on to consider an essay by Joseph Ratzinger, which discusses the preconditions for interreligious prayer and is very sceptical about its possibility, except perhaps for Christians and Jews. Finally, one of Ratzinger's preconditions for interreligious prayer is used to examine the possible grounds for interreligious prayer between Christians and Muslims, and the article argues that the door is as yet neither closed nor open.     

The effect of state anxiety on the online and offline control of fast target-directed movements

In target-directed aiming, afferent information is used to adjust limb trajectories during movement execution (i.e. online) and to enhance the programming of subsequent trials (i.e. offline). The objective of the present study was to determine the influence of state anxiety on both online and offline afferent information processing for the first time. Participants practiced either a directional aiming task (Experiment 1) or an amplitude aiming task (Experiment 2) without anxiety before being transferred to a high anxiety condition. In both experiments, results revealed that anxiety resulted in a decrement in performance. Furthermore, use of afferent information to adjust movement trajectories online was disrupted when movements were performed with anxiety, whereas there were no differences in the offline processing of afferent information between the low anxiety and high anxiety conditions.     

Beyond conscientiousness: Career optimism and satisfaction with academic major

The study focuses on psychological predictors of academic major satisfaction. According to the career construction theory (Savickas, 2005), vocational personality and career adaptability should generate career satisfaction. In this study, vocational personality was operationalised as Big Five conscientiousness, and career adaptability was operationalised as generalised self-efficacy and career optimism. A sample (N = 529) of university students completed an online survey. The resultant data were used to construct a structural model of the hypothesised relationships among variables. A good fitting model [χ² = 10.454 (7) p = .164; GFI = .993; CFI = .999; RMSEA < .031 (< .001–.066)] indicated that career optimism fully mediated the relationship between conscientiousness and academic major satisfaction. Results were consistent with previous research into personality and academic performance. Moreover, the results highlight the significant role of optimism in satisfaction with career generally, and studies, specifically. Suggestions are made for future research into modelling the relationships according to different academic disciplines and for the potential role of optimism as a learning objective for career education and counseling.     

Onora O’Neill: <Emphasis Type="BoldItalic">Justice Across Boundaries: Whose Obligations?</Emphasis>

This review sets out the central arguments of Onora O’Neill’s book Justice Across Boundaries: Whose Obligations? and argues that whilst she puts forward a variety of incisive criticisms of the international human rights movement she fails to present any positive argument for improving it. Ultimately the book is an exceptional piece of criticism that lacks any significant attempt to solve the many problems that O'Neill highlighted.     

The dual role of vision in sequential aiming movements

Previous research has demonstrated that movement times to the first target in sequential aiming movements are influenced by the properties of subsequent segments. Based on this finding, it has been proposed that individual segments are not controlled independently. The purpose of the current study was to investigate the role of visual feedback in the interaction between movement segments. In contrast to past research in which participants were instructed to minimize movement time, participants were set a criterion movement time and the resulting errors and limb trajectory kinematics were examined under vision and no vision conditions. Similar to single target movements, the results indicated that vision was used within each movement segment to correct errors in the limb trajectory. In mediating the transition between segments, visual feedback from the first movement segment was used to adjust the parameters of the second segment. Hence, increases in variability that occurred from the first to the second target in the no vision condition were curtailed when visual feedback was available. These results are discussed along the lines of the movement constraint and movement integration hypotheses.     

Understanding cooperation in the Prisoner’s Dilemma game

In the standard one-shot Prisoner’s Dilemma game, participants often choose to cooperate, when the optimal strategy is to defect. This puzzling finding has attracted considerable interest both in terms of possible computational frameworks for modeling human judgment, but also regarding the more general debate of human altruism. In this research, we ask how much of human behavior in this task can be explained by a putative bias for cooperative behavior and whether this, in turn, is influenced by personality. We compared performance on the standard task with performance on a matched neutral one; we manipulated the optimal strategy (defect or cooperate); and we manipulated the amount of payoff for responding optimally. Results revealed little evidence for a bias for cooperative behavior, but significant associations with the personality factors of Behavioural Activation System (BAS) Reward Responsivity and Agreeableness were found. These findings are discussed in terms of the attempt to explain judgment in one-shot, Prisoner’s Dilemma tasks with statistical or probabilistic models.
