Examining Conspiracist Beliefs About the Disappearance of Amelia Earhart

Previous studies have suggested that conspiracist ideation forms part of a monological belief system in which one conspiracist idea acts as evidence for new conspiracist ideas. Here, we examined this possibility in relation to an event lacking reliable or conclusive evidence, namely the disappearance of Amelia Earhart and Fred Noonan. A total of 914 members of the British general public completed scales measuring their beliefs about the disappearance of Earhart and Noonan, belief in conspiracy theories, the Big Five personality factors, support for democratic principles, political cynicism, self-esteem, and self-assessed intelligence. Results showed that belief in conspiracy theories was associated with the endorsement of less plausible explanations for the disappearance of Earhart and Noonan. In addition, belief in less plausible explanations was also significantly associated with lower self-assessed intelligence, greater political cynicism, lower self-esteem, and higher Agreeableness scores. These results are discussed in relation to monological belief systems.     

Assessing conspiracist beliefs across societies: Validation of the Serbian adaptation of the Generic Conspiracist Beliefs Scale (GCBS)

Initial validation of the Generic Conspiracist Beliefs Scale (GCBS) identified five correlated factors: Government Malfeasance, Malevolent Global Conspiracies, Extraterrestrial Cover-up, Personal Well-being and Control of Information. Despite replications of this structure, ensuing research, mostly using translated versions of the GCBS (i.e., Persian and Japanese), has reported factorial alternatives. Concomitantly, researchers postulated that belief in conspiracies was higher in historically troubled societies (e.g., Serbia). To further assess the cultural stability of the five correlated factor solution and test the assumption that GCBS scores are affected by social-political instability, a Serbian adaptation of the GCBS was assessed alongside the standard English language version. Data were collected from Serbian (n = 259, 44.40% males) and UK samples (n = 402, 52.25% males). Within samples, confirmatory factor analysis replicated the five-factor solution. Additionally, national and gender invariance was confirmed. National comparisons (Serbia vs. UK) revealed that the Serbian sample scored higher on Government Malfeasance, Malevolent Global Conspiracies, Personal Well-being and Control of Information, whereas the UK sample scored higher on Extraterrestrial Cover-up. There were no gender differences on GCBS factors. Findings indicated that while the Serbian GCBS was interpreted similarly to the GCBS, societal factors influenced endorsement of belief facets.     

我们需要一场医疗观念的革命——关于文化医学与物种医学的思考

现代文明的本质特征是用文化秩序取代自然秩序,用文化选择取代自然选择。现代文明的生活方式同人的生命原理的冲突,是现代许多疾病产生的文化根源。因而我们需要一种对现代疾病的“文化治疗”。传统医学只是关注个体生命的“个体医学”。由于个体健康同物种健康之间的内在冲突,我们需要一种防止物种衰退的“物种医学”。     

Beliefs as inner causes: The (lack of) evidence

Many psychologists studying lay belief attribution and behavior explanation cite Donald Davidson in support of their assumption that people construe beliefs as inner causes. But Davidson’s influential argument is unsound; there are no objective grounds for the intuition that the folk construe beliefs as inner causes that produce behavior. Indeed, recent experimental work by Ian Apperly, Bertram Malle, Henry Wellman, and Tania Lombrozo provides an empirical framework that accords well with Gilbert Ryle’s alternative thesis that the folk construe beliefs as patterns of living that contextualize behavior.     

Development of the Japanese Version of the Achievement Emotions Questionnaire – Elementary School (AEQ-ES-J)1,2

The purpose of this study was to develop and validate a Japanese version of the Achievement Emotions Questionnaire – Elementary School (AEQ-ES), which assesses enjoyment, anxiety, and boredom experienced by elementary school students within the settings of attending class, doing homework, and taking tests. Japanese elementary school students (n = 863 for the first survey; n = 332 for the second survey) participated in the questionnaire survey. The results showed that the psychometric properties of the Japanese AEQ-ES were comparable to those of the original version. Moreover, the results showed that students' achievement emotions were associated with their control and value appraisals, as well as their academic motivation, learning strategies, academic performance, and support from teachers. These results indicated that the Japanese version of the AEQ-ES was a good measure of elementary school students' emotions and supported the propositions of the control–value theory of achievement emotions.     

The Development and Testing of a New Version of the Cognitive Reflection Test Applying Item Response Theory (IRT)

The cognitive reflection test (CRT) is a short measure of a person's ability to resist intuitive response tendencies and to produce a normatively correct response, which is based on effortful reasoning. Although the CRT is a very popular measure, its psychometric properties have not been extensively investigated. A major limitation of the CRT is the difficulty of the items, which can lead to floor effects in populations other than highly educated adults. The present study aimed at investigating the psychometric properties of the CRT applying item response theory analyses (a two‐parameter logistic model) and at developing a new version of the scale (the CRT‐long), which is appropriate for participants with both lower and higher levels of cognitive reflection. The results demonstrated the good psychometric properties of the original, as well as the new scale. The validity of the new scale was also assessed by measuring correlations with various indicators of intelligence, numeracy, reasoning and decision‐making skills, and thinking dispositions. Moreover, we present evidence for the suitability of the new scale to be used with developmental samples. Finally, by comparing the performance of adolescents and young adults on the CRT and CRT‐long, we report the first investigation into the development of cognitive reflection.

Development and validation of the General Risk Propensity Scale (GRiPS)

Despite the widespread interest in understanding and identifying risk takers by psychologists, clinicians, and economists, the risk literature currently lacks consensus regarding the nature of risk taking and its measurement. Existing measures of risk taking are predominantly domain‐specific despite emerging support for risk taking as a domain‐general disposition. In the present paper, we examine the nature of risk taking as a domain‐general personality disposition and develop a concise measure: the General Risk Propensity Scale (GRiPS). Data from 1,523 participants across five studies provided evidence for its construct validity. The GRiPS converged with other self‐report measures of risk taking and provided incremental prediction of work, academic, and life outcomes over and above the five‐factor model of personality and the Domain‐Specific Risk Taking Scale.     

Modeling the Structure of the Attitudes and Belief Scale 2 using CFA and Bifactor Approaches: Toward the Development of an Abbreviated Version

The Attitudes and Belief Scale-2 (ABS-2: DiGiuseppe, Leaf, Exner, & Robin, 1988. The development of a measure of rational/irrational thinking. Paper presented at the World Congress of Behavior Therapy, Edinburg, Scotland.) is a 72-item self-report measure of evaluative rational and irrational beliefs widely used in Rational Emotive Behavior Therapy research contexts. However, little psychometric evidence exists regarding the measure's underlying factor structure. Furthermore, given the length of the ABS-2 there is a need for an abbreviated version that can be administered when there are time demands on the researcher, such as in clinical settings. This study sought to examine a series of theoretical models hypothesized to represent the latent structure of the ABS-2 within an alternative models framework using traditional confirmatory factor analysis as well as utilizing a bifactor modeling approach. Furthermore, this study also sought to develop a psychometrically sound abbreviated version of the ABS-2. Three hundred and thirteen (N = 313) active emergency service personnel completed the ABS-2. Results indicated that for each model, the application of bifactor modeling procedures improved model fit statistics, and a novel eight-factor intercorrelated solution was identified as the best fitting model of the ABS-2. However, the observed fit indices failed to satisfy commonly accepted standards. A 24-item abbreviated version was thus constructed and an intercorrelated eight-factor solution yielded satisfactory model fit statistics. Current results support the use of a bifactor modeling approach to determining the factor structure of the ABS-2. Furthermore, results provide empirical support for the psychometric properties of the newly developed abbreviated version.     

Development of the Generic Multifaceted Automaticity Scale (GMAS) and preliminary validation for physical activity

ObjectivesThis article presents the validation of a Generic Multifaceted Automaticity Scale (GMAS) assessing the automatic properties of habitual behaviours.DesignA quantitative approach was adopted within various adult samples in order to confirm the internal and external validity of the GMAS pertaining to Physical Activity (PA).MethodStudy 1 investigated the content validity of a series of items among experts (N = 13) and respondents (N = 26). Study 2 examined the scale's construct validity for PA (N = 293). Study 3 tested the GMAS external validity (N = 161). Study 4 evaluated the internal consistency and predictive validity for the GMAS applied to transportation modes (N = 167). Study 5 used a 1-week prospective design and included Theory of Planned Behaviour (TPB; Ajzen, 2012) variables in order to test the predictive validity of the GMAS for active transportation (N = 125).ResultsStudy 1 supported the fact that the 9 items primarily reflected one facet of automaticity. Study 2 validated the hierarchical structure of the scale. In Study 3, convergent validity was confirmed regarding PA through significant correlations with the Self-Report Behavioural Automaticity Index (SRBAI; Gardner et al., 2012) and predictive validity was supported by significant correlations with self-report PA behaviour. Study 4 confirmed its internal consistency and predictive validity. Study 5 demonstrated that the scores derived from the GMAS significantly predicted active transportation behaviour, above and beyond TPB constructs.DiscussionThe GMAS appears as a valid instrument for research on everyday PA behaviours.     

Development and preliminary validation of the Penny Beliefs Scale – Weapons (PBS-W)

Weapons carrying and use is an area of increasing concern and frequent media attention. Despite this, there is a distinct lack of psychological research into the reasons that people carry and use weapons. At present there is no adequate measure of beliefs that facilitate carrying and using weapons and the present investigation sought to develop and validate such a tool: the Penny Beliefs Scale - Weapons (PBS-W). The PBS-W was developed using themes identified in a literature review and through consultation with experienced Forensic Psychologists. The factor structure, reliability, and validity were ascertained by administering the PBS-W to 212 school pupils in South Wales, who were aged between 16 and 18 years. The final version of the PBS-W comprises of 36 items that measure young people’s beliefs about carrying and using weapons and load onto one factor named Potency. The new scale has excellent internal reliability (Cronbach’s alpha of .92), extremely good test-retest consistency (ICC = .833), male participants scored significantly higher on the PBS-W compared with female participants, and the PBS-W is significantly positively correlated with self-reported delinquency. These findings are discussed in the context of existing literature and future potential directions for research are proposed.     

Validation of a Japanese Version of the Work Engagement Scale for Students

We sought to verify the reliability and validity of the Japanese version of the Utrecht Work Engagement Scale for Students (UWES‐S‐J). We examined 824 university students. We calculated the goodness of fit for a single‐factor model and the three‐factor model. The fit to the data was better for the three‐factor than for the single‐factor model, but all factors were highly positively correlated. Additionally, the UWES‐S‐J had good internal consistency and test–retest reliability. For the content validity, there were significant positive correlations between the UWES‐S‐J score and social support, a resilience scale, and subjective happiness. The UWES‐S‐J has good reliability and validity and may therefore be used to assess study engagement among Japanese students.     

Further Psychometric Evaluation of the Japanese Version of an Academic Self-Concept Scale

In the present study, the author replicated earlier research (Paik & Michael, 1999) seeking additional information on the reliability and construct validity of a Japanese academic self-concept scale, a 70-item questionnaire comprising S subscales (Aspiration, Anxiety, Academic Interest and Satisfaction, Leadership and Initiative, and Identification vs. Alienation). A sample of 1% Japanese high school students completed the scale. Internal consistency reliability for the S subscales ranged from .75 to .87. Confirmatory factor analyses performed on several alternative models showed that the a priori 5-factor model fit the observed data best—a finding consistent with the previous study. Results of Z tests revealed statistically significant score differences between genders and between high and low academic achievers.     

Psychological Abuse Experienced in Groups Scale: Psychometric Properties of the Japanese Version

The purpose of this study was to adapt the Psychological Abuse Experienced in Groups Scale (PAEGS) for use in the Japanese population. This scale evaluates the frequency with which an individual has experienced psychologically abusive behaviors within a group. A questionnaire was administered to 130 former members of abusive groups and to a comparison sample composed of 124 former members of non‐abusive groups. The main results showed a one‐dimensional factor structure and an adequate reliability score. Significant correlations were found between the PAEGS and a group abusiveness measure, providing evidence of convergent validity. In addition, high discriminatory power was found, determining an optimal cut‐off point to distinguish between abusive experiences and non‐abusive experiences within groups. The Japanese version of the PAEGS is able to overcome limitations of previous instruments intended to assess the phenomenon, as sufficient empirical evidence is found for its use in research. In addition, it can be useful in clinical and legal contexts to assess the degree of psychological abuse experienced by Japanese people during their involvement in certain groups.

Development and Validation of the Scientific Reasoning Scale

Scientific findings and innovations play an important role in a range of decisions faced by nonscientists, yet little is known about the skills that nonscientists need in order to read and evaluate scientific evidence. Drawing on research in public understanding of science, cognitive developmental psychology, and behavioral decision research, we develop an individual difference measure of scientific reasoning skills, defined as the skills needed to evaluate scientific findings in terms of the factors that determine their quality. We present the results of three studies assessing its psychometric validity. Our results indicate that the Scientific Reasoning Scale (SRS) is internally consistent and distinct from extant measures of scientific literacy. Participants with higher SRS scores are more likely to have beliefs consistent with the scientific consensus on potentially contentious issues, above and beyond education, political and religious beliefs, and scores on two widely used measures of scientific literacy. Participants with higher SRS scores also had better performance on a task requiring them to analyze scientific information. Our results suggest that the SRS provides a theoretically informed contribution to decoding lay responses to scientific results and controversies. Copyright © 2015 John Wiley & Sons, Ltd.     

Rosenberg(1965)自尊量表中文版的美中不足

罗森伯格(1965)自尊量表(中文版)是目前我国心理学界使用最多的自尊测量工具,这源于它的两大优点:信效度高、简明方便。但是,该量表也存在一个突出的与文化差异有关的问题,即题目8的含义表达与西方有所不同。经统计分析发现,题目8只有按正向题记分或直接删除才能达到良好的鉴别度、提升量表的信效度。这对于当前的自尊研究和量表法都有一定启示意义。     

Development, Reliability, and Validity of the Beliefs Toward Mental Illness Scale

The present study describes the development of a new scale to measure Beliefs toward Mental Illness (BMI), which was designed to measure cross-cultural differences in such beliefs as well as to predict treatment-seeking behavior among different cultural groups. A total of 216 students participated in this study (114 Asian students and 102 American students). A series of factor analyses examining construct validity for the BMI revealed that the BMI has three dimensions, including dangerousness, poor social and interpersonal skills, and incurability. Examination of the reliability estimates for each factor revealed moderate to high internal consistency of the BMI. Comparisons between American and Asian students revealed the expected cultural differences in their beliefs toward mental illness and treatment preference.     

Factor Structure,Validity, and Reliability of the Japanese Version of the Balanced Index of Psychological Mindedness (BIPM)

This study examined the measurement properties of the Balanced Index of Psychological Mindedness (BIPM) among the Japanese population. Exploratory factor analysis was conducted to examine the factor structure of the BIPM (Study 1) among 464 university students, and confirmatory factor analysis examined the validity and reliability of the BIPM (Study 2) among 321 university students. Additionally, the mitigation effect of psychological mindedness (PM) for depressive symptoms was examined. The results showed a two-factor structure (Interest and Insight) similar to the original BIPM. The BIPM was negatively correlated with the alexithymia score and positively correlated with the Psychological Mindedness Scale and Openness. It was also significantly correlated with future depressive symptoms. The BIPM is useful for measuring PM in the Japanese population. Additionally, this study suggests clinical applications of PM in psychotherapy and the treatment effect mechanism of cognitive behavioral therapy.     

Assessing the Factorial Validity of the Attitudes and Belief Scale 2-Abbreviated Version: A Call for the Development a Gold Standard Method of Measuring Rational and Irrational Beliefs

Rational emotive behaviour therapy (REBT) does not possess a measure of rational and irrational beliefs that meets internationally recognised standards for acceptable psychometric properties. Without such a measure the theory/practice of REBT cannot be rigorously evaluated, thus undermining its scientific veracity. The current study investigates the validity and reliability of a recently developed measure of rational and irrational beliefs: the Attitudes and Belief Scale 2-Abbreviated Version (ABS-2-AV). University students from three countries completed the ABS-2-AV (N = 397). An alternative models framework using confirmatory factor analysis indicated that a theoretically consistent eight-factor model of the ABS-2-AV provided the best fit of the data. A number of post hoc modifications were required in order to achieve acceptable model fit results, and these modifications revealed important methodological limitations with the ABS-2-AV. Results indicated that the validity of the ABS-2-AV was undermined due to items measuring both the psychological process of interest (rational and irrational beliefs) and the context in which these beliefs processes are presented. This is a serious methodological limitation of the ABS-2 and all questionnaires derived from it, including the ABS-2-AV. This methodological limitation resulted in the ABS-2-AV possessing poor internal reliability. These limitations are discussed in relation to the broader REBT literature and the impact such problems have on research and practice. A call is made for REBT researchers to come together to develop a “gold standard” method of assessing rational and irrational beliefs that meets international standard for psychometric excellence.
