The construct validity and reliability of the 1987 Perceived Physical Competence Scale of Lintunen were examined to assess the applicability of the instrument for use with adolescents with disabilities. Subjects were 51 girls and 34 boys ( M age = 15.1 yr.) from several schools in central Finland. Principal component factor analysis with varimax rotation yielded the same two factors for adolescents with disabilities as reported for nondisabled adolescents in the related literature. Cronbach alphas for the two factors were .89 and .56. It was concluded that the scale is an appropriate measure for adolescents with disabilities. Statistical analysis indicated no gender differences for adolescents with disabilities. When compared with nondisabled groups in the related literature, these adolescents had perceived fitness similar to nondisabled peers but significantly lower than that of athletes without disabilities.

The objective of this study is to explore the intellectual capital establishing factors especially for SME's. Intellectual capital constitutes intangible asset that will add the value of the company to achieve competitive excellence. Quantitative data analysis derives from the survey towards 87 middle range manages using jugdment sampling technique. The data was analysed using cronbach's alpha test to measure the reliability; exploratory factor analysis and confirmatory factor analysis with VARIMAX rotation were applied to measure factor analysis. Research location took place at two largest clusters of Batik Industry in Central Java that are Pekalongan and Laweyan-Surakarta city. The result shows that SME's batik in Central Java has an intangible asset. The factors of intellectual capital on batik SME's consists of the human capital, structural and relational capital.

Abstract Introduction This study developed Brazilian psychodynamic psychotherapy (PDT) and cognitive-behavioral therapy (CBT) prototypes for children with internalizing disorders (ID) and externalizing disorders (ED). Method Eighteen Brazilian experts in PDT (n = 9) and CBT (n = 9) rated the 100 items of the Child Psychotherapy Q-Set (CPQ) describing a hypothetical typical session based on their respective theoretical backgrounds for children with ID. They then rated the same items describing a hypothetical typical session for children with ED. A Q-type factor analysis with varimax rotation was performed. Results Expert correlations were high within each theoretical approach and each diagnostic category. The factor analysis identified three independent factors. CBT ratings concentrated on one factor, while PDT ratings loaded onto one factor describing treatment of children with ID and another factor describing treatment of children with ED. Conclusion The sole CBT prototype reflected a general conceptualization of this approach and was undifferentiated regarding treatment of children with ID and ED. The PDT prototype for children with ID provided evidence of a process focused on interpretation, while the PDT prototype for children with ED characterized a supportive process with attention to the therapeutic relationship. This infers greater variation in the PDT setting for children with different conditions.

Components Analysis

Because of the still imperfectly understood basic factor structure of the MMPI, a Principal Components Analysis and Varimax Rotation was conducted on the MMPI item responses of 50 female undergraduate students of Education at Massey University. Eight factors were extracted which were named: Neuroticism, Anti-social behavior, Fundamentalist religiosity, Subjectivity, Introversion, Paranoic tendency, Depression and Physical symptoms. The possibly different factor structure for males and females needs explication in further work.

This study examined idiosyncratic reality claims, that is, irrational or paranormal beliefs often claimed to enhance relaxation and happiness and reduce stress. The Smith Idiosyncratic Reality Claims Inventory and the Smith Relaxation Dispositions Inventory (which measures relaxation and stress dispositions, or enduring states of mind frequently associated with relaxation or stress) were given to 310 junior college student volunteers. Principal components factor analysis with varimax rotation identified five idiosyncratic reality claim factors: belief in Literal Christianity; Magic; Space Aliens; After Death experiences; and Miraculous Powers of Meditation, Prayer, and Belief. No factor correlated with increased relaxation dispositions Peace, Energy, or Joy, or reduced dispositional somatic stress, worry, or negative emotion on the Smith Relaxation Dispositions Inventory. It was concluded that idiosyncratic reality claims may not be associated with reported relaxation, happiness, or stress. In contrast, previous research strongly supported self-affirming beliefs with few paranormal assumptions display such an association.

Confirmatory Factor

This study aimed to determine the reasons why Filipinos were not engaged in online shopping. Toward this aim, 400 respondents answered a 23-item questionnaire. It was revealed that most of the respondents were male, single, and at least college graduates. They were employees, belonged to diverse economic backgrounds, had computer and Internet access at home, and owned ATM cards. The majority did not have a credit card. Exploratory factor analysis using varimax rotation revealed that there were four reasons why respondents were not engaged in online shopping. These reasons were availability of mall services (M), quality issues (Q), price concerns (P), and interest (I). Confirmatory factor analysis reduced the number of items of MQPI from 23 to 17 items. It was disclosed that the constructs were of good fit. Discriminant validity showed that all reasons were distinct from one another. Convergent validity of the constructs was also achieved. MQPI was able to capture 72% of the reasons why Filipinos were not engaged in online shopping. Implications and directions for future research that could be derived from this study were also presented.

Abstract Background Residents receive little information about how they interact with patients. Objective This pilot study assessed the feasibility and validity of a new 16-item tool developed to assess patients' perspectives of interns' communication skills and professionalism and the team's communication. Methods Feasibility was determined by the percentage of surveys completed, the average time for survey completion, the percentage of target interns evaluated, and the mean number of evaluations per intern. Generalizability was analyzed using an (evaluator:evaluatee) × item model. Simulated D studies estimated optimal numbers of items and evaluators. Factor analysis with varimax rotation was used to examine the structure of the items. Scores were correlated with other measures of communication and professionalism for validation. Results Most patients (225 of 305 [74%]) completed the evaluation. Each survey took approximately 6.3 minutes to complete. In 43 days over 18 weeks, 45 of 50 interns (90%) were evaluated an average of 4.6 times. Fifty evaluations would be required to reach a minimally acceptable coefficient (0.57). Two factor structures were identified. The evaluation did not correlate with faculty evaluations of resident communication but did correlate weakly (r  =  0.140, P  =  .04) with standardized patient evaluations. Conclusions A large number of patient evaluations are needed to reliably assess intern and team communication skills. Evaluations by patients add a perspective in assessing these skills that is different from those of faculty evaluations. Future work will focus on whether this new information adds to existing evaluation systems and warrants the added effort.

The Oost Interest Inventory was administered to 69 English, 126 Economy and 110 Chemistry students during 1993, to obtain information on construct validity. Except for the area Physical Activities all the differences between the means were significant. Product-moment correlations for related areas across instruments ranged from .15 to .66 and for unrelated areas from .03 to .14. Principal factor analysis with varimax rotation yielded three factors, namely, Arts, Science and Economy–Numbers.
