The purposes of the current study were to verify the correlation between product and process performance of basketball passing and shooting skills and to examine the effects of TGfU intervention in a basketball camp format on process and product performance of these skills in children. Participants included 18 novices (age: M = 10.89, SD = 1.02 years old) in basketball. They participated in 22.5 hours of TGfU training over five consecutive days and completed pre and post assessments. Data were collected using process and product assessments, and a declarative knowledge questionnaire. Results showed no correlation between the dependent variables. Significant differences between pre-and posttest were found only for process performance of passes, product performance of shooting in game context, and declarative knowledge of both skills. No differences were found for product-oriented assessment of shooting and passing isolated skills. Therefore, it was possible to conclude that the use of process and product assessments to evaluate sport-specific skills after a TGfU intervention in a basketball camp may provide different and complementary information about performance levels in teaching -learning process.

The aim of this study was to validate an instrument for assessing procedural tactical knowledge (PTKT: Bb) of basketball players from 12 to 19 years old in 3vs.3 situations in half court (protocol A) and full court (protocol B). Evidence of content validity, reliability, and construct validity was investigated by calculating the Content Validity Coefficient (CVC), the Cohen's Kappa Coefficient and performing an exploratory factorial analysis (EFA), respectively. Content analysis was performed by 5 basketball coaches. 161 male basketball players aged between 12 and 19 years performed the protocols. The assessments of two basketball coaches were used to calculate within and between observer reliability for the PTKT: Bb. CVC values were above .80 for language clarity, theoretical relevance, and practical relevance. Cohen's Kappa Coefficient indicated substantial within and between observer agreement for protocol A. EFA indicated two final factorial models for protocol A. Values of Kaiser-Meyer-Olkim, factor loading, and communalities were above .50 for protocol A. The percentage of explained variance was 70%. In conclusion, PTKT: Bb presented moderate psychometric properties, which suggests that procedures for validating this instrument should continue. Este estudio tuvo como objetivo desarrollar y validar preliminarmente un instrumento para medir el conocimiento tác-tico de procedimiento en el baloncesto (TCTP: Bb), para practicantes de 12 a 19 años, en situación de juego de 3vs.3 en media cancha (protocolo A) y toda la cancha (protocolo B) oficial de baloncesto. Se investigaron las evidencias de validez de contenido, confiabilidad y validez de constructo, por medio del cálculo del Coeficiente de Validez de Contenido (CVC), Coeficiente de Kappa de Cohen y análisis factorial exploratorio (AFE) respectivamente. En el análisis de contenido participaron cinco técnicos de baloncesto. En el procedimiento de campo participaron 161 jugadores de baloncesto del sexo masculino de los 12 a los 19 años. La confiabilidad intra e interobservadores del TCTP: Bb se estableció por medio de la participación de dos técnicos de baloncesto. El cálculo del CVC reportó valores superiores a .80 para claridad de lenguaje, pertinencia práctica y relevancia teórica. El cálculo del Kappa reportó una concordancia sustancial intra e inter observadores para el protocolo A. La AFE apuntó dos modelos factoriales finales para las acciones individuales y de grupo sólo para el protocolo A. Los valores del KMO, las cargas factoriales y las comunalidades para el protocolo A presentaron valores superiores a .50. El porcentaje de varianza explicada fue del 70%. Se concluye que el TCTP: Bb presentó preliminarmente propiedades psicométricas razonables, por lo que se sugiere proseguir con los procedimientos de validación del instrumento.Palabras clave: validación; baloncesto; conocimiento táctico de procedimiento; Test.
