The Relationship

BackgroundNegative symptoms and cognitive deficits in schizophrenia are partially overlapping. However, the nature of the relationship between negative symptoms and cognition remains equivocal. Recent reviews have demonstrated the presence of two negative symptom subdomains, diminished emotional expression (DEE) and avolition. In view of this, we sought to clarify the relationship between negative symptoms and cognitive domains.MethodA total of 687 participants with schizophrenia were assessed on measures of psychopathology and cognition. Three cognitive factors, namely executive function, fluency/memory and speed/vigilance were computed from the cognitive tests. Confirmatory factor analysis was utilized to examine if a one-factor or two-factor negative model was applicable to our sample. Subsequently, the relationships between negative symptoms and cognition were examined using structural equation modeling.ResultsResults demonstrated that the two-factor model fitted the data well. While negative symptoms were mildly to moderately associated with cognition, we found that DEE had unique associations with cognition compared to social avolition, contributing to the validity of the constructs and suggesting the possibility of common underlying substrates in negative symptoms and cognition.ConclusionsOur study highlighted the need to classify DEE and social avolition separately as both are necessary in refining the complex relationship between negative symptoms and cognition as well as potentially guiding treatment and management of schizophrenia.

The present paper reexamines the psychometric properties of the Quality Perception Questionnaire (QPQ), an Italian survey instrument measuring patients’ perceptions of the quality of a recent hospital admission experience, in a sample of 4400 patients (Mage = 56.42 years; SD = 19.71 years, 48.8% females). The 14-item survey measures four factors: satisfaction with medical doctors, nursing staff, auxiliary staff, and hospital structures. First, we tested two models using a confirmatory factor analysis (structural equation modeling): a four orthogonal factor and a four oblique factor model. The SEM fit indices and the χ² difference suggested the acceptance of the second model. We then did a simulation using a bootstrap with 1000 replications. Results confirmed the four oblique factor solution. Third, we tested whether there were significant differences with respect to age or sex. The multivariate general linear model showed no significant differences in the factors with respect to sex or age.

This research is new in its attempt to take future time orientation, morningness orientation, and prospective memory as measures of mental prospection, and to examine a three-factor model that assumes working memory, mental prospection, and cognitive insight are independent but related higher-order cognitive constructs by using confirmatory factor analysis (CFA). The three-factor model produced a good fit to the data. An alternative one-factor model was tested and rejected. The results suggest that working memory and cognitive insight are distinguishable, related constructs, and that both are distinct from, but negatively associated with, mental prospection. In addition, structural equation modeling (SEM) showed that working memory had a strong positive effect on cognitive insight and a moderate negative effect on mental prospection.

Abstract In this study, fast fashion concept is investigated in order to understand the motivations of the consumers that make them adopt these products because of their willingness for the innovativeness. The relationship between the motivational factors which were named as “Social or status image” and “Uniqueness” as expressions of individuality, “Conformity” and the willingness for “Innovativeness” is analyzed using a conceptual model. Exploratory factor analysis, confirmatory factor analysis and structural equation modeling were used to analyze and validate the model. The data used for the study was obtained from 244 people living in Turkey. The findings showed that the motivational factors “Social or status image” and “Uniqueness” as expressions of individuality are influential on the consumers’ willingness for “Innovativeness”.

Purpose The purpose of this paper is to investigate the mediating effect of practicing core values on the relationship between authentic leadership and work engagement in a Korean corporate environment. Design/methodology/approach Self-report data on authentic leadership, practicing core values, and work engagement were obtained from 281 employees of three major corporations in South Korea. Structural equation modeling was adopted to analyze the data. Findings The results revealed a direct and significant influence of authentic leadership on both practicing core values and work engagement. In addition, practicing core values was found to have a partial mediating effect on the relationship between authentic leadership and work engagement. Research limitations/implications This study revealed a three-factor model of authentic leadership compared to the four-factor model found in western cultural contexts. Similar findings are indicated for other Asian countries. A rigorous future study is warranted to validate the psychometric structure across different cultural settings. Harman’s single factor test was performed to address the common method variance issue. Practical implications Practicing core values functioned as a catalyst for developing authentic leaders. Therefore, it is necessary that organizational development practitioners perform developmental activities to purposefully facilitate practicing core values. Originality/value The study falls under the isolated or disregarded researched topic of the practicing core values in relation to authentic leadership and work engagement.

Tacit knowledge is considered an effective new structure to predict an individual's job performance. We administered the Tacit Knowledge Inventory for Managers to 127 Chinese enterprise managers; of these participants, 121 also completed the NEO-Five-Factor Inventory measure of Big Five personality traits. A confirmatory factor analysis supported the structure of tacit knowledge, in which we posited a 2-factor model of context substructure. Structural equation modeling path analysis demonstrated that neuroticism was a positive predictor of total and local tacit knowledge scores; that conscientiousness was a positive predictor of total, local, and global tacit knowledge scores; and that agreeableness was a positive predictor of total and local tacit knowledge scores.

The Relationship

We evaluated the relationship between workaholism and 2 individual difference variables relevant to an organizational context, namely: proactive personality and locomotion orientation. Specifically, we examined working excessively (WE), working compulsively (WC), and perceived self-efficacy, proactivity, and locomotion in a sample of nurses working in an Italian public hospital. Data were analyzed using confirmatory factor analysis and structural equation modeling. Because WE and WC were not distinct factors, a unitary workaholism factor was used when applying regression analysis. As expected, workaholism was related negatively to proactivity, and positively to locomotion. In contrast, its relationship with self-efficacy was nonsignificant. The practical implications of our findings and future research directions are discussed.

Background:This article describes the adaptation of the Athletic Identity Questionnaire (AIQ) for Adolescents for use with children and evaluates its construct validity. Based on a theoretical model supported in adults and adolescents, the AIQ-Child measures the general attribute of athletic, which encompasses exercise, sport, and physical activity and assesses 4 dimensions: appearance, competence, importance of activity, and encouragement from 3 sources (parents, friends, teachers/other adults).Methods:The hypothesized 4-factor model was tested using structural equation modeling in 2 samples of 9- and 10-year-old children that were ethnically diverse (N = 432) and Hispanic (N = 504).Results:Confirmatory factor analysis using LISREL 8.71 supported the 4-factor structure in a 40- or 38-item version in sample 1 (RMSEA = .039, .041) and sample 2 (RMSEA = .038, .038). As in the adult and adolescent models, there was also support for a higher-order model. The AIQ-Child factors were positively related to physical activity (r = .51 to .68) and fitness (r = .15 to .41) and negatively related to TV/computer use (r = –.28 to –.03) and adiposity (r = –.32 to .04).Conclusions:Findings support the factorial and construct validity of the AIQ-Child and its use as a self-report instrument in younger children.

Analyze Data

Some studies have already analyzed what makes individuals achieve happiness. In the consumer behavior perspective, experiential consumption, which refers to the interaction between the consumer and the product or service during the purchase or consumption, is more closely related to the welfare and happiness than material consumption – the later related to good’s possession. However, there have been few studies analyzing the relationship between shopping or consumption experiences and happiness. In this sense, the general objective of this paper is to analyze the happiness in the experiences of purchase and consumption. In order to achieve that, two quantitative studies were conducted based on a survey and an experimental design. Confirmatory Factor Analysis (CFA), Structural Equation Modeling (SEM) and ANOVA were used to analyze data. Results indicate that the hedonic values drive the individual experience of purchasing and consuming towards happiness. In addition, they show that extraordinary experiences lead the individual to higher levels of happiness than ordinary ones.

The current study aims at examining the relationship between the perfectionism two-factor model (i.e., concerns and strivings) and burnout dimensions measured by using the BAT (Burnout Assessment Tool) through a longitudinal study. A two-wave cross-lagged study was conducted using path analysis in SEM (Structural Equation Modeling) of 191 workers. Results confirmed the predictive role of perfectionistic concerns on the burnout dimensions, whereas perfectionistic strivings were not significantly related, suggesting that perfectionism should be monitored by employers and clinicians to prevent employee burnout. Limitations and future research directions are envisaged.
