Windows to Research: Increasing Children’s Self–Esteem Through Supportiveness Training for Youth Sport Coaches

 

Adapted from Smoll, F.L., Smith, R.E., Barnett, N.P., & Everett, J,J. (1993). Enhancement of Children’s Self-Esteem Through Social Support Training for Youth Sport Coaches.  Journal of Applied Psychology, 78, 602-610.

 

Historically, few aspects of personality have received greater theoretical and research attention than self-esteem.  Although self-evaluations may relate to specific areas of experience, such as social, academic, and athletic domains, most theorists also subscribe to a more encompassing construct of global self-esteem that refers to one’s generalized sense of self-worth.  This construct appears to be plausible on both theoretical and research-driven grounds. 

          Traditionally, society has viewed self-esteem to be a product of social interaction.  This focus can be seen in the vast amount of previous research that has been conducted on this topic within the family and school settings.  However, a less studied social setting that may also influence a child’s developing self-esteem is organized sports.

          In this study, eight male coaches of Little League Baseball players were trained in a 2 1/2-hour preseason workshop designed to increase their supportiveness and instructional effectiveness when interacting with the players on their respective teams (click here for a more detailed description of the workshop coaching guidelines).   As a comparison group, ten coaches from two other leagues were not given the workshop.  To assess the effectiveness of the coach training, boys (N=152) from all three leagues were interviewed in the preseason and postseason.  In the interview, each boy filled out a questionnaire that measured his general self-esteem.  There were 14 descriptive statements on the questionnaire, each of which was rated on a 4-point scale.  Six of the statements referred to positive attributes, whereas eight statements were negative self-evaluations.  The entire questionnaire provides a maximum range of scores from 14 to 56 (click here to see the self-esteem questionnaire).

Analysis of Group Equivalence

          The mean ages of the coaches and the boys and the mean number of years of total coaching experience is listed in Table 1.  Statistical analyses revealed that there were no statistically significant group differences between the experimental and control coaches for any of these three demographic variables.  Likewise, after collecting pre and postseason data for 62 boys in the experimental group and 90 boys in the control group (72% and 78% respectively), analyses revealed no statistically significant difference in age between boys in the experimental and control groups.

Self-Esteem Analyses

Analyses of the self-esteem measures, both preseason and postseason, were conducted for 147 boys because five boys in the original sample did not provide data at both times.  The preseason self-esteem questionnaire yielded nearly identical means of 47.80 (SD=4.73) for the experimental group (n=59) and 47.76 (SD= 5.76) for the control groups (n=88).  The postseason means for these two groups were 48.71 (SD=5.43) for the experimental group and 47.40 (SD=6.60) for the control groups.  Statistical analyses revealed no significant differences between the two groups in postseason means.  In addition, when postseason means were adjusted using preseason scores as a covariant (thereby removing all effects of any preseason differences), the postseason differences remained statistically non-significant.  The mean preseason and postseason self-esteem scores for all samples of boys are shown in Figure 1.

Although, it was possible that the coach training intervention had no real effect, previous evidence led the researchers to hypothesize that low self-esteem children might be more responsive to variations in coaching behaviors. The previous analyses included boys of all varying levels of self-esteem.  The researchers conducted additional statistical analyses in search of potential treatment effects for the 86 boys whose preseason self-esteem scores were below the median value of 49.  The mean preseason and postseason self-esteem scores for this subsample of boys are shown in Figure 2.

Similar to the larger sample of all boys, in this subsample there were no significant differences on the preseason self-esteem measure between the experimental group and the control group.  However, when postseason means were again adjusted using preseason as a covariate, significantly higher level of self-esteem were revealed for the boys who had played for the trained coaches (F(1,84)= 4.56, p<.05).  Further analysis of these two groups revealed that scores for the low self-esteem boys who had played for the trained coaches increased significantly.  However, scores for the low self-esteem boys in the control group showed no significant change. 

At the end of the season the researchers also asked the athletes to evaluate their experiences in Little League. There were no differences between the ratings for boys who played for trained and control coaches for 1) liking for baseball or 2) their coach's baseball knowledge.  However, the boys who played for trained coaches rated items such as 1) their fun playing baseball, 2) their liking for their coach, 3) their coach's teaching ability, and 4) how well they liked their teammates significantly higher than did the boys who played for control coaches. Additionally, because the two groups were from different leagues, there was no significant difference in their average won/loss records.

The researchers concluded that the workshops were a successful addition to the preseason preparation for Little League Baseball coaches.

 

Windows to Research Focus Questions

1. What type of experiment did the researchers conduct?

2. What was the dependent variable? The independent variables?

3. The researchers took advantage of intact groups - the different little leagues.  What steps did the researchers take to show that there were not any major differences between these intact groups at the start of the experiment?  Intact groups have the disadvantage of building possible selection confounds into an experiment.  Are there other factors that might vary systematically with the different leagues that could be possible confounding variables?

4. There were some advantages of using intact groups (separate leagues) rather than randomly assigning coaches to the control group or experimental group for this experiment.  What were these advantages?

5.  Suppose that you serve on the Board of Directors for your local Little League and would like to convince the other board members and the volunteer coaches that the Board should sponsor a preseason workshop designed to help coaches prepare to work effectively with young athletes.  How you could take advantage of the results of this applied youth-sport study to support your position?
