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.

This study investigates the equivalent factorial structure of the Brief Symptom Inventory (BSI) in clinical and nonclinical Jordanian populations, using both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The 53-item checklist was administered to 647 nonclinical participants and 315 clinical participants. Eight factors emerged from the exploratory factor analysis (EFA) for the nonclinical sample, and six factors emerged for the clinical sample. When tested by parallel analysis (PA) and confirmatory factor analysis (CFA), the results reflected a unidimensional factorial structure in both samples. Furthermore, multigroup CFA showed invariance between clinical and nonclinical unidimensional models, which lends further support to the evidence of the unidimensionality of the BSI. The study suggests that the BSI is a potentially useful measure of general psychological distress in clinical and nonclinical population. Ideas for further research are recommended.

Objective: Binge eating is a transdiagnostic construct and one of the main components of eating and emotional disorders. Meta-cognitive beliefs about eating play an important role in the maintenance of binge eating. The Eating Beliefs Questionnaire (EBQ-18) is a self-report questionnaire, which measures negative, positive, and permissive beliefs about binge eating. This cross-sectional study aims to assess the psychometric properties of the EBQ-18 in a community sample. Methods: A total of 501 participants (413=females, 88=males) were selected through multi-stage cluster sampling and were administered the EBQ-18, the Binge Eating Scale (BES), the Dutch Eating Behavior Questionnaire (DEBQ), the Body Image Concern Inventory (BICI), the Acceptance and Action Questionnaire (AAQ-II), and the Intolerance of Uncertainty Scale (UIS). Construct validity, internal consistency, convergent and divergent validity of the EBQ-18 were determined using Exploratory Factor Analysis, Confirmatory Factor Analysis. Results: The EBQ-18 possesses a three-factor structure and a high internal consistency (α=.91). The EBQ-18 showed convergent validity with the BES and the DEBQ, divergent validity with the BICI, AAQ-II, and The UIS. Conclusion: The goodness-of-fit indices were acceptable and the data showed adequate fit to the three-factor model. In conclusion, findings provide initial support for the validity and reliability of the EBQ-18.

IntroductionThe Beck Scale for Suicidal Ideation (BSS) is a self-report 19-item scale preceded by five screening items. The BSS and its screening items are intended to assess a patient's thoughts, plans and intent to commit suicide. All 24 items are rated on a three-point scale (0 to 2). In this study, scores from the five screening items were included in the overall score. Therefore, total scores could range from 0 to 48.There is no study until this date that examines the factor structure of BSS among Kuwaitis.ObjectivesThe current study investigated the original three-factor model of the (BSS) in non-clinical sample.MethodsSample one consisted of 285 males and 300 female students from Kuwait University while sample two consisted of 201 males and 302 females from Kuwait University. The Arabic version of BSS was administered to participants. Explanatory factor based on sample 1 and conformity factor analysis based on sample 2 of BSS were used in this study.ResultsThe explanatory and confirmatory factor analysis of (BSS) extracts three factors and three structures of BSS. Factor I = active suicidal desire; Factor II = preparation; Factor III = passive suicidal desire. In addition, the results revealed no significant gender differences in the factor structure of BSS.ConclusionsThe results of both confirmatory and exploratory factor analysis indicated that the original three-factor model provided the best fit for the two genders.

Given difficulty in having children assess their own behaviour, there are few self reports on child impulsivity. With the exception of Eysenck's 16 questionnaire, there are no self-report measures of impulsivity in children with good psychometric properties. The present study tested the possibility of using the adolescent version of the Barrati Impulsiveness Scale-11 with children. For this purpose the questionnaire was translated and backtranslated and administered to school children (182 boys and 195 girls) ages 8 to 12 years ( M = 10.4, SD = 0.9). The data were analysed by exploratory factor analysis, to evaluate the factorial structure of the questionnaire, the fit of the proposed solution, and internal consistency reliabilities. Results seem to indicate that this questionnaire may be useful in assessing impulsivity in children. The three-factor structure showed slight differences with the initial questionnaire proposed by Barratt and had good or sufficient internal consistency (depending upon the scale) across the 8- to 12-yr.-old age range.

"Introduction: Place attachment is multi-dimensional and depends on a reciprocal relationship between behavior and experience. It comes from environmental psychology, and it has its roots in the theory of attachment because of an emotional link between an individual and a place. The present paper aims to describe the psychometric characteristics of the Slovak version of The Workplace Attachment Styles Questionnaire (Srima, 2018). Methods: The original questionnaire consists of 15 items with a Likert scale ranging from totally disagree to agree. The research sample consisted of 645 working adults of a convenience sample, aged from 16 to 78 years, consisting of 54.9% women, from various work fields (finance, sales, education). We randomly divided the sample into two halves for separate studies. Results: In the first study with 323 adult participants, we used exploratory factor analysis to examine its construct validity. According to exploratory factor analysis, we reduced the 15-item questionnaire to a 9-item structure with three original factors: secure (AM = 6.23, SD = 2.32), dismissive (AM = 3.64, SD = 2.54), and preoccupied (AM = 3.64, SD = 2.31) workplace attachment styles, with an average internal consistency of 0.75. In the second study with 322 participants, we executed the confirmatory factor analysis, which confirmed the three-factor structure, with an average internal consistency of 0.65. Discussion: The results confirmed the original three-factor structure of The Workplace Attachment Styles Questionnaire with 9 original items instead of 15. This paper contributes to the shorter version of the Workplace Attachment Styles questionnaire adapted to the Slovak population. The study's limitations are the absence of other measurement tools that could verify the construct of workplace attachment itself (Adult Attachment in the Workplace, Experience in Close Relationship Questionnaire). That is also what is worth doing in the next research."

Purpose – Validated and reliable measure of littering attitude is lacking, therefore the purpose of this paper is to describe the development and psychometric evaluation of the littering attitude scale (LAS) as a new self-report measure to assess littering attitude. Design/methodology/approach – The internal consistency reliability and validity of LAS were investigated in a cross-sectional survey of 1,360 urban residents in a South-western State in Nigeria. Data were analysed using reliability analysis, exploratory factor analysis, and structural equation modeling. Findings – Item analysis and exploratory factor analysis suggested a 15-item scale with one general underlying factor. Reliability analysis score for the 15-item scale revealed a Cronbach α coefficient of 0.87. The scores of the LAS items indicated good internal consistency and construct validity consistent with the principles of scale development. The scale also showed a good fit in confirmatory factor analysis for the sample. Research limitations/implications – The aims of the study related to determining the validity, appropriateness, utility and feasibility of LAS were achieved. However, further studies should be done to validate the scale in other cultural settings. Practical implications – The findings suggested that LAS captures littering attitude and holds promise as a useful tool to conduct environmental audit by scholars, practitioners, and non-governmental organisations who are interested in the social and behavioural management of environmental quality. Originality/value – This is the first scale to measure littering attitude. The scale can be used by practitioners and researchers to conduct benchmarking studies on littering attitude.

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.

Weight Stigmatization

The present study was intended to develop a scale to measure perceived weight stigmatization among people with obesity. The study was conducted in five steps. In first step, three focus group discussions were conducted with female obese university students to get the first-hand information related to weight stigmatization. Step two involved four interviews which were conducted with male obese university students to collect detailed information about weight stigmatization experiences of men. Step three included content analysis of qualitative data for item generation. In step four, judge’s opinion was taken, and a committee approach was carried out to select the items for the initial form of the scale. Items for final form of the scale were selected through exploratory factor analysis and confirmatory factor analysis in step five. For exploratory factor analysis, 150 university students (men = 61, women = 89) were included in the sample, whereas, for confirmatory factor analysis, another group of students (men = 78, women = 72) participated in the study. Principal Component Factor Analysis revealed three meaningful structures including Self-Perception, Perceived Social Rejection, and Perceived Impact containing 43 items. Confirmatory factor analysis confirmed this factor structure and all 43 items possessed factor loadings greater than .40. Moreover, results indicated that perceived weight stigmatization had high internal consistency (Cronbach’s alpha = .96) with three subscales having internal consistency .95, .83, and .92 respectively. Therefore, Perceived Weight Stigmatization Scale turned out to be a reliable and valid instrument for measuring perception of weight stigma in adults with obesity.

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.

Abstract Background Studies of psychological distress in Sierra Leone have typically used measures which were developed for use in other contexts, and which often have not been adapted or validated for use in Sierra Leone. This has resulted in a lack of reliable information about the patterns of psychological distress within the population, which is a barrier to the development of effective and appropriate mental health services. The aim of the study was to develop a locally-appropriate measure of psychological distress for Sierra Leone. Methods The new measure consists of two instruments: the Sierra Leone Psychological Distress Scale (SLPDS) and a gendered measure of ability to carry out daily tasks—a Function scale—as an indication of the severity of distress. A three-phase mixed methods exploratory sequential study was conducted. Phase 1 was item generation and testing, leading to the development of a set of potential items for both instruments. Phase 2 was a small pilot study (N = 202) leading to the selection of the final set of items for both measures. Phase 3 was a validation phase where the SLPDS and the Function scale were administered with a larger sample of 904 respondents. Item analysis was used to assess the internal consistency of the scales, and Exploratory Factor Analysis to explore the properties of the SLPDS. Results Exploratory factor analysis using the principal axis factoring with an oblique rotation identified a three-factor structure for the 18-item SLPDS. Internal consistency for the SLPDS (Cronbach’s alpha = 0.89) and three subscales was good (Cronbach’s alpha > 0.73). The internal reliability of the male and female versions of the Function scale was also found to be acceptable (Cronbach’s alpha = 0.90 for the female scale and 0.79 for the male scale). Conclusions Together the SLPD and Function scales provide a locally-validated tool which will enable government bodies and local and international non-governmental organisations in Sierra Leone to assess mental health and psychosocial needs. This will support both effective service provision and the evaluation of initiatives designed to improve mental health and psychosocial wellbeing.
