ENThis research was aimed at evaluating the psychometric properties of Lithuanian version of Leadership Scale for Sports (LSS). The work applied Leadership Scale for Sports (Chelladurai and Saleh, 1980), which comprises 40 items grouped in five subscales: "training and instruction", "democratic behaviour", "autocratic behaviour", "social support" and "positive feedback". The adaptation of the scale was carried out it the following stages: forward translation (1), expert panel back translation (2), pre-testing and cognitive interview (3), preparation and application of the final version (4). The participants of the research included basketball players aged between 12 and 18 years old (boys, n=227). Test-retest reliability with regard to repeated research was carried out 3 weeks subsequently after the primary research. The participants of the research had to evaluate every statement of Leadership Scale for Sports using a 5-point Likert scale, ranging from "strongly disagree" to "strongly agree". In order to evaluate the internal consistency of LSS and its subscales, Cronbachs’s Alpha coefficient has been calculated, the scale stability in respect of repeated research has been measured using Spearman-Brown coefficient. The analysis of research data has been carried out using SPSS 21.0. Research results confirmed the reliability of LSS in respect of repeated research (Spearman-Brown 0.816). The rates of internal consistency confirmed compatibility of questions according to the phenomenon being measured (Cronbach Alpha 0,911). The rates of internal consistency among LSS subscales "training and instruction", "democratic behaviour", "social support" and "positive feedbac"’ ranged from 0,709 to 0,883, subscale "autocratic behaviour" – 0,583. The analysis of LSS subscales demonstrated a strong correlation between "social support" and ".There was a moderate correlation between "training and instruction" and "democratic behaviour" (r=0.585, p<0.01), ‘training and instruction’ and ‘social support’ (r=0.609, p<0.01). "Positive feedback" correlated with "social support" (r=0.484, p<0.01) and coach’s "democratic behaviour" (r=0.506, p<0.01). Research results showed that LSS is suitable for opinion evaluation of basketball players aged between 12 and 18 in respect to coach leadership, however, the evaluation of items in subscale ‘autocratic behaviour’ could be specified.
