Transformational Leadership, Task-Involving Climate, and Their Implications in Male Junior Soccer Players: A Multilevel Approach

Despite the well-known positive consequences of transformational coaches in sport, there is still little research exploring the mechanisms through which coaches’ transformational leadership exerts its impact on athletes. Multilevel SEM was used to examine the relationship between coaches’ transformational leadership style, a task-involving climate, and leadership effectiveness outcome criteria (i.e., players’ extra effort, coach effectiveness, and satisfaction with their coach), separately estimating between and within effects. A representative sample of 625 Spanish male soccer players ranging from 16 to 18 years old and nested in 50 teams completed a questionnaire package tapping the variables of interest. Results confirmed that at the team level, team perceptions of transformational leadership positively predicted teams’ perceptions of task climate, which in turn positively predicted the three outcome criteria. At the individual level, players’ perceptions of transformational leadership positively predicted teams’ perceptions of task climate, which in turn positively predicted teams’ extra effort and coach effectiveness. Mediation effects appeared at the team level for all the outcome criteria, and at the individual only for extra effort. Transformational leadership is recommended to enhance task climate, in order to increase players’ extra effort, their perceptions of the effectiveness of their coach, and their satisfaction with his/her leadership style

Reference variables for analysing inflation in Spain

Artículo de revistaThis note analyses the main reasons why the Directorate General Economics, Statistics and Research of the Banco de España has recently adopted the Harmonised Index of Consumer Prices (HICP) and its associated measure of core inflation (the HICP excluding energy and food) as its reference variables for analysing inflation in Spain, instead of its previous practice of focusing on the consumer price index (CPI) and the CPI excluding unprocessed food and energy. The advantages in terms of communication and consistency with the other euro area countries and the European Central Bank (ECB) make it advisable to base the regular analysis of price developments on the harmonised measures. In any case, the CPI will continue to be analysed regularly, given its more extensive regional coverage and longer time serie
