The purpose of the study was to determine the peculiarities of programmed teaching of a cartwheel to boys aged 14. Material and methods. The study participants were 20 boys aged 14. The children and their parents were fully informed about all the features of the study and gave their consent to participate in the experiment. To solve the tasks set, the following research methods were used: study and analysis of scientific and methodological literature; pedagogical observation, timing of training tasks; pedagogical experiment, methods of mathematical statistics, factor analysis. Results. The analysis of similarities revealed that the program components are interrelated. Series of training tasks I, II and IV are combined into one group and provide conditions for teaching boys aged 14 a cartwheel. Conclusions. As a result of factor analysis, the study obtained a two-factor model of the teaching program where training tasks are closely connected with one another, which indicates their effective selection. Factor models of the teaching program explain 69.371% and 75.394% of the variation of results. The study found that the effectiveness of the program depends on the modes of exercise repetition. The use of the mode of exercise repetition of 6 sets 2 times each with a rest interval of 60 s increases the effectiveness of the proposed program (p <0.05).

Results. The analysis of similarities revealed that the program components are interrelated. Series of training tasks ІV, V and VI have the highest correlation. Series of training tasks І, ІІІ and IV are combined into one group and provide conditions for teaching girls aged 15 the cartwheel. Conclusions. The study obtained factor models of the teaching program, which explain 70.645% and 68.468% of the variation of results. The models characterize the two-factor structure of the teaching program where training tasks are closely connected with one another, which indicates their effective selection. It was found that the tasks of series I, II and III, and the tasks of series III, IV and V are most connected with one another, which confirms the combined nature of the method of algorithmic instructions. Optimization of the number of repetitions of the entire exercise (series of tasks VI) depends on the amount of exercises of the second and fifth series of training tasks.

The Pittsburgh Sleep Quality Index (PSQI) is a widely used measure for assessing sleep impairment. Although it was developed as a unidimensional instrument, there is much debate that it contains multidimensional latent constructs. This study aims to investigate the dimensionality of the underlying factor structure of the PSQI in a multi-ethnic working population in Singapore. The PSQI was administered on three occasions (baseline, 3 months and 12 months) to full-time employees participating in a workplace cohort study. Exploratory factor analysis (EFA) investigated the latent factor structure of the scale at each timepoint. Confirmatory factor analysis (CFA) evaluated the model identified by EFA, and additionally evaluated it against a single factor and a three-factor model. The EFA identified a two-factor model with similar internal consistency and goodness-of-fit across each timepoint. In the CFA, the two- and three-factor models were both superior to the unidimensional model. The two- and three-factor models of the PSQI were reliable, consistent and provided similar goodness-of-fit over time, and both models were superior to the unidimensional measure. We recommend using the two-factor model to assess sleep characteristics in working populations in Singapore, given that it performs as well as the three-factor model and is simpler compared to the latter.

In this study, the authors adopted Lou and Noels’s (2016, 2017) Language Mindset Inventory. This was administered to students (N = 825) at 2 universities in southwestern Japan. Factor analysis revealed a 4-factor model, as opposed to the 3- and 6-factor models found by Lou and Noels, suggesting a limited fit within a Japanese EFL context. Regression analysis was used to compare students’ mindsets with their EFL proficiency, revealing a small effect size but positive correlations with growth mindsets and no correlation with fixed mindsets, suggesting that whether students subscribe to growth or fixed mindsets does play a part in proficiency, however, a limited one. Further implications are discussed. 本研究では、Lou and Noels（2016, 2017）のLanguage Mindset Inventoryを採用した。これは、学生の（growth/fixed＝成長型の・固定型の）mindsets（考え方）を明らかにする診断ツールである。調査は、西南日本の2つの大学の学生（N = 825）を対象に実施された。因子分析では、Lou and Noels（2016, 2017）の3因子および6因子モデルとは対照的に、4因子モデルが明らかになった。回帰分析では、学生のmindsetsとEFLの習熟度を比較し、効果量は少ないがgrowth mindsetsとの正の相関関係を明らかにし、fixed mindsetsとの相関関係がないことを示し、英語の習熟には、学生が成長型の考え方（growth mindsets)をするか、または固定型の考え方（fixed mindsets）をするかが、限定的ではあるが、関与していることを示唆する 。さらなる分析の含意についても議論する。

The Family Adaptability and Cohesion Scale III (FACES-III) has been widely used to measure an individual’s family functioning in terms of cohesion and adaptability. In Malaysia, the FACES-III has been translated into the Malay language for the community, but its psychometric properties in this context remain unknown. Thus, the purpose of this research is to examine the psychometric properties of the Malay version of the FACES-III in 852 adolescents attending secondary schools in Kuala Lumpur, Malaysia. Data were randomly split into two halves: the exploration sample and the validation sample. Exploratory factor analysis was conducted on the exploration sample and a two-factor model was discovered after removing nine items that showed low factor loading. Then, confirmatory factor analysis was conducted on the validation sample to compare the one-factor models, two-factor models, and three-factor models. Results showed that the 11-item two-factor model (FACES-III-M-SF) was superior to the other competing models. Both the exploratory and confirmatory factor analyses replicated the two-factor structure of the original version of FACES-III. The reliability of the overall scale was consistently good, but the subscale results were mixed. This suggests that researchers should use the overall score, but not the subscale scores, in analyses.

Abstract. This paper compared two higher-order factor models using a 100-item, five-factor personality inventory originating from the IPIP database. The sample consisted of 2,019 subjects tested on the Internet. The two models were compared using confirmatory factor analysis. The two-factor model showed a similar fit to the data. The criteria for parsimony favored a hierarchical model with one higher-order factor at the top and five personality factors beneath. The single higher-order factor was found to be related to social desirability in a subsample of 196 subjects.

The Impact

Purpose. To determine the impact of exercise modes on the effectiveness of teaching girls aged 14 the cartwheel. Materials and methods. The study participants were 20 girls aged 14. The children and their parents were fully informed about all the features of the study and gave their consent to participate in the experiment. To solve the tasks set, the following research methods were used: study and analysis of scientific and methodological literature; pedagogical observation, timing of training tasks; pedagogical experiment, methods of mathematical statistics, discriminant analysis. Results. The study found that statistically significant differences in the number of repetitions were observed in performing all series of training tasks, except the third one (p < 0.05). The girls aged 14 who used the first mode (6 sets 1 time each with a rest interval of 60 s) needed fewer repetitions to master the movements of the first, second, fourth, fifth, and sixth series of tasks (p < 0.05). The girls aged 14 who used the second mode (6 sets 2 times each with a rest interval of 60 s) needed fewer repetitions to master the movements of the third series of tasks (p < 0.05). Conclusions. Discriminant analysis made it possible to determine the impact of the number of repetitions on the effectiveness of developing the cartwheel skill in girls aged 14. Based on the analysis of group centroids, it was found that exercise modes significantly influence the cartwheel skill development in girls aged 14 during physical education classes. The results of classification of the groups show that 100.0 % of the original grouped cases were classified correctly.

Character Independence

Character independence is an important assumption in parsimony-based phylogenetic analysis. For taxa with extant representatives, the analysis of within-species covariation of quantitative characters provides a basis for assessing character independence. One promising approach is to use mean species scores on factors of within-species covariation as phylogenetic characters, but the use of common morphometric factor models leads to problems with either the independence or the interpretability of such characters. Principal components and principal factors, whether rotated or not, may be constrained to be orthogonal but may be difficult to interpret since the effects of each factor are spread over all variables. In Wright-style factor analysis the restriction of secondary factors to subsets of variables facilitates their interpretation, but the factors may be highly correlated.An alternative approach is to adopt a hierarchical factor model in which correlated first-order factors are restricted to subsets of the variables. Size is modelled as a second-order factor inducing correlation of the primary factors, in contrast to the common morphometric procedure of attempting to partial out size in the first stage of analysis. The size-independent components of the primary factors provide shape characters which are interpretable as the deviations of regional growth from their predictions based on size. Hierarchical factor models have been widely used in psychometric studies since their introduction by Thurstone in the 1930's, but have been little used in morphometric analyses.The hierarchical model is applied to the covariances of interlandmark trusses measured on skulls of extant canids using a video-based stereophotogrammetric system. Preliminary results indicate that the canid skull may be partitioned into discrete regions of relatively independent local growth.

Abstract. The Therapist Adherence Measure (TAM-R) is a central assessment within the quality-assurance system of Multisystemic Therapy (MST). Studies into the validity and reliability of the TAM in the US have found varying numbers of latent factors. The current study aimed to reexamine its factor structure using two independent samples of families participating in MST in the Netherlands. The factor structure was explored using an Exploratory Factor Analysis (EFA) in Sample 1 ( N = 580). This resulted in a two-factor solution. The factors were labeled “therapist adherence” and “client–therapist alliance.” Four cross-loading items were dropped. Reliability of the resulting factors was good. This two-factor model showed good model fit in a subsequent Confirmatory Factor Analysis (CFA) in Sample 2 ( N = 723). The current finding of an alliance component corroborates previous studies and fits with the focus of the MST treatment model on creating engagement.
