El Athlete Burnout Questionnaire (ABQ) se ha convertido en el instrumento más utilizado para evaluar el burnout en el contexto deportivo, lo que ha permitido un incremento significativo en las investigaciones. A pesar de ello, una revisión en la literatura revela que no existen trabajos que proporcionen datos psicométricos del ABQ con muestra mexicana, por lo que el objetivo de la presente investigación fue analizar las propiedades psicométricas del Athlete Burnout Questionnaire en deportistas mexicanos. El análisis de los datos se desarrolló a través de 2 estudios, aplicando el cuestionario en el primero de ellos a una muestra de 464 jóvenes deportistas entre 13 y 18 años de edad (M = 14.85, DT = 1.45). Los resultados del Análisis Factorial Confirmatorio (AFC) indicaron índices de ajuste aceptables (c2 = 176.7; c2 /gl = 2.18; p < .01; TLI = .93, IFI = .95, CFI = .95 y RMSEA = .05) así como pesos de regresión aceptables para la estructura trifactorial del cuestionario original. Para el segundo estudio se utilizó una muestra de 1009 deportistas mexicanos entre 12 y 39 años de edad (M = 17.28, DT = 2.98). Los resultados del AFC encontraron suficiente evidencia para la validez de constructo (c2 = 419.5; c2 /gl = 5.59; p < .01; TLI = .94, IFI = .96, CFI = .96 y RMSEA = .07). Los resultados en el análisis de correlación entre el Athlete Burnout Questionnaire (ABQ) y el Athlete Engagement Questionnaire (AEQ) pueden considerarse como prueba favorable de la validez discriminante. En cuanto a la fiabilidad, se encontraron resultados aceptables en consistencia interna en ambas fases del estudio, concluyendo que el ABQ es una herramienta útil para evaluar el burnout en depotistas mexicanos. The Athlete Burnout Questionnaire (ABQ) has become one of the most used tools to assess burnout in sport contexts. Despite a significant increase in research in this field, the literature has shown that there are no papers which provide psychometric data of the ABQ using a Mexican sample. Hence the objective of the present study was to analyze the psychometric properties of the Athlete Burnout Questionnaire of Mexican athletes. Data analysis was obtained using two studies. The first study consisted of 464 young athletes between 13 and 18 years old (M = 14.85, DT = 1.45). The results of the Confirmatory Factor Analysis (CFA) showed acceptable fit indices (c2 = 176.7; c2 /gl = 2.18; p < .01; TLI = .93, IFI = .95, CFI = .95 y RMSEA = .05) Acceptable results of load regression were also found for the original three factor questionnaire. A sample of 1009 Mexican athletes between 12 and 39 years of age (M = 17.28, SD = 2.98) were used for the second study. The results of the CFA found sufficient evidence for the construct validity (c2 = 419.5; 2cc2 /gl = 5.59; p < .01; TLI = .94, IFIS = .96, CFI = .96 and RMSEA = .07). The results in the analysis of correlation between the Athlete Burnout Questionnaire (ABQ) and the Athlete Engagement questionnaire (AEQ) can be considered as evidence of the discriminant validity. In regard to reliability, acceptable results were observed in internal consistency in both phases of the study, concluding that the ABQ is a useful tool to evaluate the burnout in Mexican athletes.

Value Measurement

This paper addresses the issues of methodological problems and limitations regarding measuring values. A short scan review of values measurement methods from psychological and ethnobotanical approaches was made to enumerate some of those shortcomings. A new methodological approach, named Kab&rsquo;s Value Survey (KVS) was proposed and compared with other well adopted methods based on some important criteria to assess its suitability, uniqueness and novelty. The results of the comparisons shows that KVS for its considerations to the theoretical explanations distinguishes itself over other methods of value measurement in the sense that the methodological approach employed is more broad in scope and applications, simple, specific and reliable in terms of instruments for data collection, psychometric data analysis, and of course data presentation. The method however solved some of the criticized limitations that exist in other well adopted methods of values measurement from psychological and ethnobotanical perspectives.

It is well established that unique physiological information can be obtained by rapidly freezing cells in various functional states and analyzing the cell element content and distribution by electron probe x-ray microanalysis. (The other techniques of microanalysis that are amenable to imaging, such as electron energy loss spectroscopy, secondary ion mass spectroscopy, particle induced x-ray emission etc., are not addressed in this tutorial.) However, the usual processes of data acquisition are labor intensive and lengthy, requiring that x-ray counts be collected from individually selected regions of each cell in question and that data analysis be performed subsequent to data collection. A judicious combination of quantitative elemental maps and static raster probes adds not only an additional overall perception of what is occurring during a particular biological manipulation or event, but substantially increases data productivity. Recent advances in microcomputer instrumentation and software have made readily feasible the acquisition and processing of digital quantitative x-ray maps of one to several cells.

Purpose The purpose of this study was to explore the perceptions of special education practitioners (i.e., speech-language pathologists, special educators, para-educators, and other related service providers) on their role as communication partners after participation in the Social Communication and Engagement Triad (Buckley et al., 2015 ) yearlong professional learning program. Method A qualitative approach using interviews and purposeful sampling was used. A total of 22 participants who completed participation in either Year 1 or Year 2 of the program were interviewed. Participants were speech-language pathologists, special educators, para-educators, and other related service providers. Using a grounded theory approach (Glaser & Strauss, 1967 ) to data analysis, open, axial, and selective coding procedures were followed. Results Three themes emerged from the data analysis and included engagement as the goal, role as a communication partner, and importance of collaboration. Conclusions Findings supported the notion that educators see the value of an integrative approach to service delivery, supporting students' social communication and engagement across the school day but also recognizing the challenges they face in making this a reality.

The communicative performance of 4 preoperational-level adolescents, using limited speech, gestures, and communication board techniques, was examined in a two-part investigation. In Part 1, each subject participated in an academic interaction with a teacher in a therapy room. Data were transcribed and coded for communication mode, function, and role. Two subjects were found to predominantly use the speech mode, while the remaining 2 predominantly used board and one other mode. The majority of productions consisted of responses to requests, and the initiator role was infrequently occupied. These findings were similar to those reported in previous investigations conducted in classroom settings. In Part 2, another examination of the communicative performance of these subjects was conducted in spontaneous interactions involving speaking and nonspeaking peers in a therapy room. Using the same data analysis procedures, gesture and speech modes predominated for 3 of the subjects in the nonspeaking peer interactions. The remaining subject exhibited minimal interaction. No consistent pattern of mode usage was exhibited across the speaking peer interactions. In the nonspeaking peer interactions, requests predominated. In contrast, a variety of communication functions was exhibited in the speaking peer interactions. Both the initiator and the maintainer roles were occupied in the majority of interactions. Pertinent variables and clinical implications are discussed.
