The purpose of this study was to create and validate a measure for jazz theory knowledge assessment. The Jazz Theory Measure (JTM) was created by exploring publications on jazz improvisation instruction and research studies that utilized jazz theory as a significant aspect of the study (i.e., dependent variable, independent variable, data collection). Latent jazz theory components (i.e., Key Knowledge, Scale Knowledge, and Chord Knowledge) were identified from an exploration of the literature and each was paired with several subtests. Items representing the JTM ( N = 60) demonstrate significant representation of the jazz theory components through alpha reliability (.98), and confirmatory factor analysis (standardized root mean square residual [SRMR] = .0327, comparative fit index [CFI] = .930, Tucker–Lewis index [TLI] = .907) providing support for the JTM as a valid and reliable measure of jazz theory knowledge. Further analysis suggests that music educators providing instruction in jazz improvisation should focus on building a foundation of jazz theory in the first 5 years of jazz instruction.

The purpose of this study was to test a hypothesized model that proposes a causal relationship between motivation and academic achievement on the acquisition of jazz theory knowledge. A reliability analysis of the latent variables ranged from .92 to .94. Confirmatory factor analyses of the motivation (standardized root mean square residual [SRMR] = .067) and jazz theory (SRMR = .063) measures indicated a good fit of the predicted model to the observed data. Results of the latent path model indicated good fit (χ2 = 20.08, p = .692, df = 24, N = 102) and large, positive, and statistically significant direct effects of motivation (β = 0.65) and academic achievement (β = 0.56) on jazz theory knowledge acquisition. The successful identification of this proposed model lends enough support for continued investigation into the process surrounding the acquisition of jazz theory knowledge.

RESUMO Objetivo: Conduzir uma discussão sobre as estratégias adotadas para avaliação da estrutura fatorial de instrumentos psicométricos utilizando como exemplo os modelos fatoriais do Body Shape Questionnaire (BSQ). Métodos: Foram avaliados sete modelos fatoriais diferentes do BSQ, que foram obtidos por meio de análise fatorial exploratória (AFE) e estão apresentados na literatura. A análise fatorial confirmatória desses modelos foi realizada para a amostra de estudo utilizando-se aos índices qui-quadrado pelos graus de liberdade (χ2/gl), Comparative Fit Index (CFI), Tucker-Lewis index (TLI), Root Mean Square Error of Approximation (RMSEA) e Weighted Root Mean Square Residual (WRMR). As validades convergente e discriminante foram avaliadas a partir da variância extraída média e do coeficiente de determinação entre os fatores do BSQ, respectivamente. A confiabilidade dos modelos foi avaliada a partir da confiabilidade composta e do coeficiente alfa de Cronbach. Resultados: Participaram 739 universitárias com média de idade de 20,4 (desvio-padrão = 2,4) anos. Todos os modelos apresentaram adequado ajustamento para a amostra de estudo, contudo a validade discriminante esteve comprometida neles. A confiabilidade dos modelos também foi adequada. Conclusão: Apesar de todos os modelos testados do BSQ apresentarem bons indicadores psicométricos, salienta-se que eles foram obtidos em amostras diferentes utilizando-se AFE e sem justificativa teórica plausível para a construção dos fatores, o que pode dificultar a escolha de um modelo para utilização em ambiente clínico. Assim, diante da importância de preservação do conceito teórico durante o desenvolvimento do instrumento, sugere-se cautela na utilização de modelos sem sustentação teórica.

Adult sportspersons (Masters athletes, aged 35 years and older) have unique coaching preferences. No existing resources provide coaches with feedback on their craft with Masters athletes. Three studies evaluated an Adult-Oriented Coaching Survey. Study 1 vetted the face validity of 50 survey items with 12 Masters coaches. Results supported the validity of 48 items. In Study 2, 383 Masters coaches completed the survey of 50 items. Confirmatory factor analysis and exploratory structural equation modeling indicated issues with model fit. Post hoc modifications improved fit, resulting in a 22-item, five-factor model. In Study 3, 467 Masters athletes responded to these 22 items reflecting perceptions of their coaches. Confirmatory factor analysis (comparative fit index = .951, standardized root mean square residual = .036, and root mean square error of approximation = .049) and exploratory structural equation modeling (comparative fit index = .977, standardized root mean square residual = .019, and root mean square error of approximation = .041) confirmed the model. The resultant Adult-Oriented Sport Coaching Survey provides a reliable and factorially valid instrument for measuring adult-oriented coaching practices.

This study has assessed the psychometric proprieties of the Mental Toughness Inventory (MTI) within the context of Brazilian sports. About 12 professionals participated in the process of adapting and translating the scale to Brazilian Portuguese. Subjects were 575 athletes (23.54 ± 5.79 years old; 58% males) who answered the MTI and the 10-item Connor–Davidson Resilience Scale (CD-RISC-10). Data were analyzed through confirmatory factor analysis (CFA), Cronbach's alpha (α), composite reliability (CR), average variance extracted (AVE), Spearman correlation, and model invariance tests. Results from CFA showed adequate fit for the original 8-item structure of the scale [Chi-square (χ2) = 27.041; p = 0.078; normalized chi-square (χ2/df) = 1.50; comparative fit index (CFI) = 0.988; Tucker–Lewis Index (TLI) = 0.981; root mean square error of approximation (RMSEA) = 0.03 [0.00–0.05]; standardized root mean residual (SRMR) = 0.030] assessing mental toughness (MT) as a single factor and the scale presented satisfactory internal consistency (CR = 0.81; α = 0.82). MT was correlated with resilience (r = 0.607), age (r = 0.276), and time of experience in the sport (r = 0.215). The MTI has also shown partial measurement invariance for sex and complete invariance across sport types. It was concluded that the MTI is a suitable tool for assessing MT in the present sample of Brazilian athletes; this instrument has potential practical application for researchers and sports psychologists who seek to develop the well-being and performance of athletes.

This research was done to find if using maximum likelihood could reduce the Interactive Optimism Scale-Garcia to a new valid and reliable shorter version. There were 502 adults: 263 women and 239 men ( Mage = 34.67, SD = 12.27). It was used in confirmatory factor analysis. A four-item scale is obtained, having excellent goodness of fit: [χ2/ df = .609, GFI (Jöreskog and Sörbom’s Goodness-of-Fit Index) = .999, NFI (Normed Fit Index) = .999, CFI (Bentler’s Comparative Fit Index) = 1.000, RMSEA (Steiger–Lind root mean square error of approximation) = .000 (90% CI = .0001, .077); SRMR (standardized root mean square residual) = .007], as well as factorial invariance across sexes; the scale has good internal consistency (ω = .869, α = .858, ordinal α = .906). Brief Interactive Optimism Scale-G correlates significantly with self-esteem ( r = .779, p < . 01, 95% CI [.816, .736]), depression ( r = −.810, p < .01, 95% CI [.843, .772]), and psychopathy ( r = −.670, p < . 01, 95% CI [.723, .611]). In conclusion, Brief Interactive Optimism Scale-G is a good option for measuring optimism in Mexicans.

Background and Purpose: The Modified Reminiscence Functions Scale (MRFS) measures the patterns and functions of reminiscence. The purpose of this study was to examine the factor structure of the MRFS in a sample of community-dwelling Black adults. Methods: A convenience sample (N= 335) of Black adults from the Northeast completed the 39-item MRFS. Seven- and 8-factor models were evaluated given the uncertainty regarding the number of factors in previous reminiscence research. Results: Confirmatory factor analysis established validity of the 7-factor model (relative chi-square [χ2/df] = 1.9, Tucker-Lewis index [TLI] = .919, comparative fit index [CFI] = .929, root mean square error of approximation [RMSEA] = .05). Reliability of the subscales ranged from .64 to .90. Conclusions: The MRFS is a reliable and valid measure of reminiscence patterns and functions in Black adults with similar characteristics.

Zusammenfassung. Zur Erfassung der 3 Emotionsregulationsstrategien Unterdrücken, Anpassen / Neubewerten und Akzeptieren wurde der Affective Style Questionnaire für Jugendliche (ASQ-Y) adaptiert und an einer entsprechenden Stichprobe (N = 1 092) validiert. Die Dimensionalität des englischen Originalfragebogens und der deutschen Version für Erwachsene konnte auch für Jugendliche bestätigt werden. Während der Analyse kam das ESEM-Verfahren (Exploratory Structural Equation Modeling) zum Einsatz, die Kennwerte bewegten sich im akzeptablen bis sehr guten Bereich. Der Comparative Fit Index (CFI) erreichte einen akzeptablen Wert von .938, ebenso der Tucker–Lewis Index (TLI) mit einem Wert von .911. Der Root Mean Square Error of Approximation (RMSEA) lag bei einem sehr guten Wert von .050, das Standardized Root Mean Square Residual (SRMR) erreichte einen guten Wert von .030. Die internen Konsistenzen der 3 Skalen (Unterdrücken: α = .77; Anpassen / Neubewerten: α = .76; Akzeptieren: α = .76) erreichten (vergleichbar mit dem englischen Original und der deutschen Erwachsenenstichprobe) zufriedenstellende Werte. Die Subskalen zeigten hypothesenkonforme diskriminante und konvergente Zusammenhänge mit etablierten Verfahren des Forschungsbereichs Emotionsregulation, was für die Konstruktvalidität spricht. Insgesamt ist der ASQ-Y als Messinstrument zur Erfassung von verschiedenen Emotionsregulationsstrategien bei Jugendlichen geeignet und ökonomisch in seiner Anwendung. Der ASQ-Y kann in der Allgemeinbevölkerung und in der Prävention eingesetzt werden. Nach entsprechender Validierung ist der Einsatz auch im klinischen Setting möglich.

The posthumous organ donation reasoned action scale (PODRAS) may be the first multidimensional scale measuring individuals’ perceptions, which is developed based on the Theory of Reasoned Action and guided by empirical data. This study moves further to validate the scale and examine its psychometric properties. Two hundred and twenty-one university students participated in the study. Results suggested that the scale has a structure with six dimensions: Mutilation and Imperfectness, Legacy for Family, Altruism, Detachment, Eradication of Hope, and Burden on Family. The scale was evaluated with acceptable to good psychometric properties and model fit (χ2/ df = 1.58; root mean square error of approximation = .07; standardized root mean square residual = .08; comparative fit index = .92; incremental fit index = .92; Tucker–Lewis index = .90). Construct validity was also supported. The study has significant contributions that theoretically, the scale proposed a conceptualization framework in understanding posthumous organ donation, whereas methodologically, the scale serves as a tool that facilitates future studies of organ donation behaviors.
