There is a need for a questionnaire that quantifies what students actually experience during martial arts (MA) training. Although no such measure exists, having one would allow researchers to identify the specific components of the MA training experience that may benefit participants’ health outcomes, and permit MA training organizations to implement control and consistency measures. In this article we report the development and psychometric properties of the Martial Arts Inventory (MAI). This study comprised three phases: (a) question development, (b) exploratory factor analysis (EFA), and (c) a correlational validity demonstration. We developed a 106 item questionnaire and then used exploratory factor analysis ( n = 252) to extract eight distinct factors (meditative training, respectful discipline, positive training environment, streaming, training behaviour, heavy training, goal orientation, and physical challenge) that were represented by 48 items. We demonstrated convergent validity through positive correlations between this questionnaire and measures of both self-regulation and mindfulness. As a first of its kind instrument, the MAI has the preliminary psychometric basis to be used by researchers and clinicians for measuring the consistency of student experiences across MA schools, and for exploring the efficacy of MA training for various applications, including participant psychosocial health outcomes. Additionally, further refinement and validity testing of this tool will be needed.

Abstract. Physical exercise when done excessively may have negative consequences on physical and psychological wellbeing. There exist many scales to measure this phenomenon. The purpose of this article is to create a scale measuring the problematic practice of physical exercise (PPPE Scale) by combining two assessment tools already existing in the field of exercise dependency but anchored in different approaches (EDS-R and EDQ). This research consists of three studies carried out on three independent sample populations. The first study (N = 341) tested the construct validity (exploratory factor analysis); the second study (N = 195) tested the structural validity (confirmatory factor analysis) and the third study (N = 104) tested the convergent validity (correlations) of the preliminary version of the PPPE scale. Exploratory factor analysis identified six distinct dimensions associated with exercise dependency. Furthermore, confirmatory factor analysis validated a second order model consisting of 25 items with six dimensions and four sub-dimensions. The convergent validity of this scale with other constructs (GLTEQ, EAT26, and The Big Five Inventory [BFI]) is satisfactory. The preliminary version of the PPPE must be administered to a large population to refine its psychometric properties and develop scoring norms.

Abstract. The Dark Triad is a constellation of three antisocial personality traits: Machiavellianism, narcissism, and psychopathy. Recently, researchers have introduced a “Dark Tetrad” that includes subclinical sadism, although others suggest considerable overlap between psychopathy and sadism. To clarify the position of sadism within the Dark Triad, an online study was conducted with 615 university students. Exploratory factor analysis revealed that a six-factor solution fit the data best, representing Machiavellianism, psychopathy, physical sadism, verbal sadism, narcissism, and vicarious sadism. Furthermore, convergent validity was supported through sadism’s correlations with the HEXACO personality traits. The results support sadism’s inclusion within the Dark Tetrad as a unique construct but with some conceptual overlap with psychopathy.

Purpose The purpose of this paper is to explore the development of innovation capability construct measures in the context of supply chain and to objectively identify the key dimensions for stimulating focal firms’ innovativeness. Design/methodology/approach The scale items for this research were obtained from extant literature. The data were collected from homogenous sample of 117 Ghanaian middle level managers (respondents). Exploratory factor analysis was used to identify the main dimensions of innovation capability. Based on the statistical analysis, four dimensions were obtained – idea management, idea implementation, collaboration and learning – and the convergent validity, discriminant validity, nomological validity and reliability tests indicate that the scales are valid and reliable Findings Four dimensions (factors) of innovation capability were identified from the exploratory factor analysis. These dimensions were labelled as idea management, idea implementation, collaboration and learning. The results indicate that the integration of the dimensions of innovation capability may stimulate a focal firm’s innovativeness. Research limitations/implications First, the measurement scale might not capture all the important dimensions of innovation capability. Second, the judgmental sampling used in this study means that the result cannot be generalised to the entire supply chain population, third, the sample was drawn from one geographical location using non-probability sampling technique. Practical implications The measures provide supply chain managers with a better approach of understanding the innovation capability in their supply chain. For instance, the measurement of supply chain’s innovation capability should help supply chain managers to determine the important innovation areas that need attention most and to permit them to respond to challenges posed by any kind of innovation capability dimension that needs to be enhanced. Originality/value The unique contribution of this paper is the development innovation capability measurement scale in the context of supply chain.

This research is a validation study of a survey instrument to assess student self-regulation which aims to fill a methodological gap by capturing self-regulation processes while completing learner-generated digital media (LGDM) assignments. For this purpose, the study developed and validated a self-regulation learning questionnaire. Data were gathered from seven science subjects (Years 1 to 3, n = 341) which used LGDM assignments during Semester 1, 2017. Students were asked to complete a 40-item online questionnaire. The questionnaire was administered at three times during the semester (Weeks 2, 6, and 10). Exploratory factor analysis was used to identify factor structures, followed by confirmatory factor analysis to test the validity of the constructs defined by exploratory factor analysis. Analysis of the data revealed a ten-factor structure – six concerning self-regulation, two concerning student attitudes towards LGDM assignments, one concerning assignment ownership, and one concerning assignment motivation. The variables empirically verified in this study have important practical implications, as they could provide educators with the direction in which to target interventions to improve learners’ experiences with LDGM. The study findings also contribute to the field by providing scholars with a validated research instrument that can be used in future studies.

In this article, we describe the development and validation of a measure of orientation toward activism in and for the Black community—the Black Community Activism Orientation Scale (BCAOS)—in a sample of Black adolescents and emerging adults. An exploratory factor analysis ( n = 446) was conducted and the results were a 26-item measure with scores of three internally consistent factors: high-risk, low-risk, and formal political activism orientation. A confirmatory factor analysis was conducted ( n = 447) and strong model fit estimates confirmed the factor structure of the exploratory factor analysis. Convergent validity was established through bivariate correlations of the BCAOS factors with social responsibility beliefs and nationalist ideology. In light of increased participation in sociopolitical movements in support of Black lives, the BCAOS can contribute to investigations of the psychology of adolescent and emerging adult activism in and for the Black community. We recommend additional scale development research to further contribute to this growing field.

Background Adequate muscle strength, power, and endurance are important in children's daily activities and sports. Various instruments have been developed for the assessment of muscle function; each measures different aspects. The Functional Strength Measurement (FSM) was developed to measure performance in activities in which strength is required. Objective The study objective was to establish the test-retest reliability and structural and construct validity of the FSM. Design A cross-sectional descriptive study was conducted. Methods The performance of 474 children with typical development on the FSM was examined. Test-retest reliability (n=47) was calculated with the intraclass correlation coefficient (2.1A) for agreement. Structural validity was examined with exploratory factor analysis, and internal consistency was established with the Cronbach alpha. Construct validity was determined by calculating correlations between FSM scores and scores obtained with a handheld dynamometer (HHD) (n=252) (convergent validity) and between FSM scores and scores on the Movement Assessment Battery for Children–2 (MABC-2) (n=77) (discriminant validity). Results The test-retest reliability of the FSM total score ranged from .91 to .94. The structural validity revealed one dimension, containing all 8 FSM items. The Cronbach alpha was .74. The convergent validity with the HHD ranged from .42 to .74. The discriminant validity with MABC-2 items revealed correlations that were generally lower than .39, and most of the correlations were not significant. Exploratory factor analysis of a combined data set (FSM, HHD, and MABC-2; n=77) revealed 2 factors: muscle strength/power and muscle endurance with an agility component. Limitations Discriminant validity was measured only in children aged 4 to 6 years. Conclusions The FSM, a norm-referenced test for measuring functional strength in children aged 4 to 10 years, has good test-retest reliability and good construct validity.

This study aims to validate Korean versions of the 9-item Utrecht Work Engagement Scale, testing for its factor pattern validity through Exploratory Factor Analysis and Confirmatory Factor Analysis, reliability, and convergent and discriminant validity. The 9-item Utrecht Work Engagement Scale was translated according to the guidelines of the International Test Commission and tested with two Korean samples. First, the Exploratory Factor Analysis found that both two-factor and three-factor solutions were viable options with the first sample. Second, comparison validations of these two solutions were tested by confirming the dimensionality of their structures through the Confirmatory Factor Analyses with the second sample, with the conclusion that the three-factor model solution was the most parsimonious model. Finally, the three-factor model of the 9-item Utrecht Work Engagement Scale was demonstrated to have good discriminant validity and convergent validity, as well as internal consistency of its subscales.

Aim: Conflict of mothers and daughters-in-law is a common issue, especially in Asian countries characterized by a collectivistic culture and a patrilineal society. The main purpose of this research was the development and validation of quality of mother and daughter-in-law’s relationship scale, including construct validity, convergent validity and internal consistency. Methods: This was a correlational research. The research's statistical population included all students' mothers in city of Ahvaz. Two samples were used in this study. In the first sample, 411 subjects were selected for exploratory factor analysis; and in the second stage, a random sample of 211 subjects were selected as a multi-stage cluster sampling for confirmatory factor analysis. Subjects completed the Quality of Mother-in-Law and Daughter-in-law Relationship Scale (QMDRS) and Miller Social Intimacy Scale (MSIS). Results: The results of the exploratory factor analysis showed that this scale consists of four factors, including kindness and empathy, control, communication, and interference. The confirmatory factor analysis results confirmed the four-factor structure of this scale. Convergent validity of QMDRS is calculated by correlating it with the Miller Social Intimacy Scale. The correlation coefficient of mean in subjects in QMDRS was significant (0.20 to 0.46). According to Cronbach's alpha, the internal consistency of the QMDRS and four factors kindness and empathy, control, communication, and interference was 0.68, 0.62, 0.72, 0.78, and 0.90. Conclusion: According to the results the Quality of Mother and Daughter-in-law’s Relationship Scale (QMDRS) has sufficient validity and reliability in Iranian families.
