The Exercise Benefits/Barriers Scale (EBBS) research instrument has been extensively used to investigate the perceived benefits and barriers of exercise in a range of settings. In order to examine theoretical contentions and translate the findings, it is imperative to implement measurement tools that operationalize the constructs in an accurate and reliable way. The original validation of the EBBS proposed a nine-factor structure for the research tool, examined the EBBS factor structure, and suggested that various factors are important for the testing of the perception of exercise benefits and barriers, whereas a few items and factors may not be vital. The current study conducted a confirmatory factor analysis (CFA) using hierarchical testing in 565 participants from the northwest region of the United Kingdom, the results of which provided evidence for a four-factor structure of the benefits measure, with the Comparative Fit Index (CFI) = 0.943, Tucker–Lewis Index (TLI) = 0.933, and root means square error of approximation (RMSEA) = 0.051, namely life enhancement, physical performance, psychological outlook, and social interaction, as well as a two-factor structure of the barrier measures, with the CFI = 0.953, TLI = 0.931, and RMSEA = 0.063, including exercise milieu and time expenditure. Our findings showed that for a six-factor correlated model, the CFI = 0.930, TLI = 0.919, and RMSEA = 0.046. The multi-group CFA provided support for gender invariance. The results indicated that after three decades of the original validation of the EBBS, many of the core factors and items are still relevant for the assessment of higher-order factors; however, the 26-item concise tool proposed in the current study displays a better parsimony in comparison with the original 43-item questionnaire. Overall, the current study provides support for a reliable, cross-culturally valid EBBS within the UK adult population, however, it proposes a shorter and more concise version compared with the original tool, and gives direction for future research to focus on the content validity for assessing the perception of the barriers to physical activity.

Research scales developed in one society are often validated in another society to determine the factor structure and measurement equivalence of the scales. Using a convenience sample of 378 respondents from two cross-sectional studies, the present analyses examined confirmatory factor analysis (CFA) and gender invariance in the Illinois Rape Myth Acceptance (IRMA) Scale in Nigeria. Specifically, the analyses examined whether the scale holds similar factor structure, whether the latent means can be compared, and whether respondents interpreted items similarly or ascribed the same meaning to them across gender. Based on the analyses, CFA results validated the hypothesized multidimensional four-factor structure of IRMA, namely, “she asked for it,” “he didn’t mean to,” “it wasn’t really rape,” and “she lied.” Similarly, the IRMA measurement was invariant (partial scalar invariance) across gender, suggesting that men and women interpreted IRMA’s items and constructs similarly. Results of an independent-samples t test suggested that women were more likely than men to reject the myth that female victim of rape “lied.” In general, preliminary findings indicated that IRMA is suitable for research on rape myths in Nigeria. Knowledge generated from its use may enhance understanding of rape myths, rape-supportive behaviors, and rape prevention and victim intervention programs.

This paper reviews empirical research on cognitive factors associated with the experience of trauma and with the development of posttraumatic stress, Acute Stress Disorder (ASD) and Posttraumatic Stress Disorder (PTSD) in children and adolescents. The review covers three main areas: cognitive experimental and neuropsychological studies; large scale studies on representative samples; and, randomized clinical trial data examining cognitive-behaviour therapy (CBT) interventions. Overall, the conclusions are that progress in all three areas lags far behind that in adult work and that, perhaps, the studies to date raise more questions than they provide answers provided by the studies to date. The paper concludes with detailed empirical recommendations for future research in the three chosen domains.

The study examined the relationship of extraversion, neuroticism, and impulsiveness with posttraumatic stress reactions of avoidance and intrusion. 36 outpatients from a Trauma Unit at a major metropolitan hospital in Melbourne (Victoria), and 24 age-matched controls completed the Impact of Event Scale, the Eysenck Personality Questionnaire Revised, and the Impulsivity Questionnaire. Intrusion symptoms were predicted both by Extraversion and Neuroticism, after controlling for age and gender, with Neuroticism making a stronger contribution to the prediction. The only predictor of Avoidance symptoms was Neuroticism. Impulsivity correlated with Intrusion symptoms but predicted them only in the trauma group. This finding, along with the observed positive associations of Extroversion with both posttraumatic symptoms, lends support to Gray's model of dispositions influencing responses to trauma, suggesting that impulsive (extroverted) neurotics are more vulnerable to posttraumatic stress than introverted ones.
