The present study examined conceptual issues surrounding celebrity worship in a Malay-speaking population. In total, 512 Malay and 269 Chinese participants from Malaysia indicated who their favorite celebrity was and completed the Celebrity Attitude Scale (CAS) as well as a range of demographic items. Results showed that the majority of Malay and Chinese participants selected pop stars and movie stars as their favourite celebrities, mirroring findings in Western settings. In addition, exploratory factor analysis revealed a three-factor solution of the CAS that was consistent with previous studies conducted in the West. Structural equation modeling further revealed that participant’s age was negatively associated with celebrity worship and that self-rated attractiveness was positively associated with celebrity worship. Overall, the present results suggest that celebrity worship in Malaysia may be driven by market and media forces, and future research may well be guided by use of the CAS.

Microaggressions are daily insults to minority individuals such as people with disabilities (PWD) that communicate messages of exclusion, inferiority, and abnormality. In this study, we developed a new scale, the Ableist Microaggressions Impact Questionnaire (AMIQ), which assesses ableist microaggression experiences of PWD. Data from 245 PWD were collected using Amazon’s Mechanical Turk (MTurk) platform. An exploratory factor analysis of the 25-item AMIQ revealed a three-factor structure with internal consistency reliability ranging between .87 and .92. As a more economical and psychometrically sound instrument assessing microaggression impact as it pertains to disability, the AMIQ offers promise for rehabilitation counselor research and practice.

Background: In Southeast Asia, the process of obtaining informed consent is influenced by both culture and policy at the hospital and national level. Both physicians and nurses play vital roles in this process, but physicians influence the roles of nurses. Objectives: Since the physicians and nurses often have different perspectives, it is important to investigate their views about the informed consent process and nurses’ roles therein and whether there is a difference between ideal and experienced practice (reality), and whether this differs across hospitals. Methods: A questionnaire was developed and a survey was conducted among physicians and nurses. Using exploratory factor analysis a three factor structure was determined: ‘nurses’ roles’, ‘barriers in informed consent’, and ‘adequacy of information’. Non-parametric tests were applied to compare nurses and physicians, and hospital setting. Participants and research context: Responses were obtained from 129 physicians and 616 nurses from two Indonesian hospitals. Those hospitals differ in ownership, location, and size. Ethical consideration: The study was reviewed by the hospital ethical committee. Participation was voluntary and confidentiality was ensured by keeping the responses anonymous. Findings: Physicians and nurses differ significantly on all three factors. The scores reflecting disparity between ideal and reality regarding nurses’ roles varied across professions, while barriers in informed consent differed between hospitals. Discussion: The differences between ideal and reality indicated that improvement in the informed consent process and nurses’ roles therein is called for. Varying views between physicians and nurses on nurses’ roles may hinder collaboration. The differences between hospital settings showed interventions may have to be customized for different settings. Conclusion: Views on nurses’ roles vary across professions. Views on barriers in informed consent vary across hospitals. Therefore interprofessional education is needed to promote interprofessional collaboration and intervention to improve informed consent practice should be tailored to the hospital context.

The Positive and Negative Affect Schedule (PANAS) was originally developed to measure two orthogonal dimensions of affect. The present study examined the factor structure of the PANAS in a sample of 302 undergraduates. Maximum Likelihood factor analysis was used to compare two- and three-factor solutions to self-rated affect. The two-factor solution resulted in confirmation of the two factors of Positive and Negative Affect hypothesized to underlie the schedule. When, however, a three-factor solution was specified, the Positive Affect factor was retained, while the Negative Affect factor split into two lower-order factors generally consistent with the Upset and Afraid factors described by Mehrabian in 1997. These findings highlight the need for research to consider the possible influence of a third affective dimension, such as Dominance–Submissiveness on self-rated affective experience.

This study examines the psychometric properties of the Russian-version of G. Spanier’s Dyadic Adjustment Scale (DAS). 302 subjects (84 couples) participated in this research and each partner responded individually to the PFB or to both scales. The results of the exploratory factor analysis revealed a three-factor structure of the scale, which was endorsed by the means of confirmatory factor analysis. Three subscales and total score revealed appropriate reliability — internal consistency and split reliability. The construct validity was confirmed by correlations between DAS subscales and other instruments testing theoretically close constructs. External validity was confirmed by correlations between DAS subscales and perfectionism which shows that mentally focusing on one’s imperfections and failures is negatively related to subjective well-being in a marriage.

The first purpose of this study was to define the construct of occupational identity and develop the scale of occupational identity, the second purpose of this study was to examine the factor structure of occupational identity using exploratory common factor analysis and test the discriminant validity of occupational identity with workplace satisfaction, and third purpose of this study was to test the model of antecedents and outcome variables of occupational identity using confirmatory factor analysis. For fulfilling these purposes, three studies were conducted. Data were gathered from 390 workers in study 1, 505 workers in study 2, 1,115 workers in study 3. As a result, the three-factor structure of occupational identity was stably replicated, although the sample was changed. The occupational identity had discriminant validity with workplace satisfaction. Except for person-occupation fit(a subfactor of occupational identity) had a high correlation with general, occupational satisfaction(a subfactor of workplace satisfaction), other subfactors of occupational identity generally had low correlations with other subfactors of workplace satisfaction. It was found that the occupational identity was derived from occupational reputation, dedication to the occupation, occupational pride, and mission to the occupation. And the occupational identity resulted in the purpose of the worker’s life and intention to continue the worker’s occupation. Based on these results, We made discussions about implications, limitations, and future research tasks.

Abstract Objective Self-report scales are commonly used to evaluate non-specific symptoms following concussion. While several scales have been developed, few were created using a systematic process and most contain several ambiguous items that may be misinterpreted. To address this, a new theoretically-based, multidimensional measure was designed to assess Cognitive, Neuropsychiatric, and Somatic symptoms associated with concussion. This study used sophisticated psychometric techniques to develop the Texas Postconcussion Symptom Inventory (TPSI) and establish initial reliability and validity. Method Because concussion symptoms are non-specific, a pool of 76 potential items was developed and administered to a diverse clinical sample (N = 350) that included patients with concussion, epilepsy, and dementia. Polychoric correlations were utilized to remove items based on poor fit/multicollinearity and an exploratory factor analysis (EFA) with an Oblimin rotation was used to determine factor structure. Results A three-factor model best fit the data, and represented Cognitive, Neuropsychiatric, and Somatic domains as designed. Ten items were discarded, resulting in a total of 66 items. The model explained 48.5% of the total variance and contained adequate sampling (Kaiser-Meyer-Olkin measure =0.92) and sufficient item correlations (Bartlett’s Test of Sphericity, p < 0.05) for EFA. All three factor structures displayed high internal consistency (Cronbach’s α > 0.88). Conclusions The TPSI is a brief, multidimensional measure with evidence of strong internal consistency and reliability as well as distinct Cognitive, Neuropsychiatric, and Somatic symptoms associated with concussion. Future research will investigate its convergent and divergent validity in concussion as compared to existing popular symptom measures.

Extreme focus on healthy eating, called orthorexia nervosa (ON), was assessed using a 21-item Eating Habits Questionnaire (EHQ). The present study aimed to validate the Polish version of the EHQ in a general population sample. Nine hundred sixty-seven women (59%) and men participated in the present study. Data was obtained from an internet-administered survey. Exploratory factor analysis with the first split sample (n = 502) produced a three-factor solution accounting for 47% of the variance. In confirmatory factor analysis with the second split sample (n = 465), the three-factor structure showed satisfactory goodness-of-fit (comparative fit index (CFI) = 0.99, root mean square error of approximation (RMSEA) = 0.008). Reliability analysis for the Polish version of the EHQ across the whole questionnaire showed strong internal consistency (α = 0.88, intraclass correlation coefficient (ICC) = 0.86). The internal consistency, measured by Cronbach’s alpha coefficients, for the EHQ subscales were 0.85 (knowledge), 0.81 (problems), and 0.81 (feelings and behaviors). Total EHQ score was positively correlated with its three subscales, cognitive restraint, uncontrolled eating, and emotional eating, and was negatively correlated with body mass index (BMI). The Polish version of the EHQ is a reliable questionnaire that can be used with confidence to better assess ON in a general population sample.

Environmental health literacy (EHL) involves understanding and using environmental information to make decisions about health. This study developed a validated survey instrument with four scales for assessing media-specific (i.e., air, food, water) and general EHL. The four scales were created as follows: 1) item generation: environmental health scientists and statisticians developed an initial set of items in three domains: knowledge, attitudes, and behaviors; 2) item review: items were reviewed for face validity; 3) validation: 174 public health students, the exploratory sample, and 98 community members, the test sample, validated the scales. The scales’ factor structure was based on exploratory factor analysis (EFA) and model fit was assessed through confirmatory factor analysis (CFA). For each scale, the final EFA resulted in an independent three-factor solution for knowledge, attitudes, and behaviors. Good fit for the three-factor structure was observed. Model fit for CFA was generally confirmed with fit indices. The scales showed internal consistency with Cronbach’s alpha from 0.63 to 0.70. The 42-item instrument represents an important contribution towards assessing EHL and is designed to enable meaningful engagement between researchers and community members about environmental health. The intended outcome is sustained community–academic partnerships benefiting research design, implementation, translation, dissemination, and community action.
