Adaptation and Application of the Scale of Intentionality to Continue Playing Youth Basketball

Several studies have highlighted the importance of psychological scales being validated in contexts in which they will subsequently be used. This is a measure that enriches the validity and reliability of the instrument. The tendency is to use sport -specific scales. The aims of this study were: (a) to know psychometric properties of the intention of being physically active adapted scale to 9-12 years old basketball players, and (b) to verify this measurement in the same basketball stage. The participants were 619 players. The instrument was adapted to obtain content validity and understanding validity. Lately, the instrument was administered to analyze construct validity (exploratory factorial analysis all items were grouped in a factor and confirmatory factor analysis ,z2/df= 3.94; SRMR = 0.015; GFI = 0.93; CFI = 0.95; TLI = 0.93; RMSEA = 0.04), criterion validity (r = 0.74; p < 0.000), internal consistency (Cronbach's alpha = 0.88), and to get information about the participants intention to continue playing basketball (M = 4.64; SD = 0.43). The scale is a contextualized, specific, valid, and reliable instrument what was reinforced by the participants' high values.
