1. Introduction
Adolescence is an important period, between the ages of 10 and 19 [
1,
2], in the development of autonomy and identity [
3], in which there is a progressive move from external (parental) regulation to self-regulation, with young people becoming increasingly responsible for their own decisions about values and their own behaviour through a process of internalisation of moral values [
4]. It is also a period of rapid development that offers an opportunity for the promotion of values that may be more durable and enduring [
5]. Several studies have shown that values develop throughout childhood and adolescence, and furthermore that the likelihood of value change decreases with age [
6,
7]. Therefore, these appear to be critical age periods in the development of values, and a comprehensive understanding of values during adolescence and young people’s experiences with values in different contexts is currently lacking [
8].
Along with their family and the educational centre, sport is one of the most important contexts in the process of a child’s formation and development. Participation in sports activities has many benefits, such as improved physical health and decreased symptoms of depression or anxiety [
9,
10], and is related to a wide range of positive personality traits [
11]. Additionally, physical activity and sport programmes in school and community contexts have the potential to foster positive development in relation to social and emotional learning [
12]. However, despite evidence of the potential benefits of sports participation, mere participation is not considered sufficient to obtain them [
13]. Sport can become an extraordinary context for transmitting a wide range of important personal and social values to children and adolescents, provided that there is an appropriate organisation and educational focus [
14,
15,
16,
17] that intentionally incorporate best practices to promote learning and life skill development through sport [
18].
One perspective of growing relevance in recent times in the fields of development, psychology and sport is the positive youth development (PYD) approach. It is a strengths-based perspective, focused on harnessing the abilities and potential that come naturally to adolescents to achieve healthy development and adaptive functioning [
19,
20], and at the same time, the capacity of young people to mitigate their risk and problem behaviours [
21]. Although the term PYD has been used in different ways and in different contexts, there are some similarities between the different models, such as the emphasis on the strengths of young people, the plasticity of their development, internal developmental assets such as psychosocial competence and external developmental assets such as community influence [
22]. All of this brings the strengths of the individual and the resources available in the environment (positive adult relationships or mentoring opportunities) into mutually beneficial interaction [
19,
23,
24].
At a global level, the PYD approach focusses on four essential domains [
25,
26]: assets (young people are able to achieve desirable outcomes as they have the necessary resources, skills and competencies), agency (they can influence and make their own decisions about their lives, set their own goals and act on their own decisions), contribution (they can engage in positive developmental change for themselves and their communities) and an enabling environment (the environment can maximise their assets, their capacity to act, their access to services and opportunities, while enhancing their ability to avoid risks and protect themselves).
In sport, the PYD approach seeks to examine the ways in which sport and physical activity can be used to optimise young people’s internal strengths and foster positive sport experiences [
27]. Different conceptual frameworks emphasise attention to the relationships between the individual and others (such as teammates, coaches and parents) and to the sport context, such as the organisational structure of the sport club or the characteristics of the community in which the young person is involved [
28]. In addition, the PYD-based programmes developed have demonstrated a positive and significant impact on the development of social skills, social competence, positive relationships, social support or life skills, among other benefits [
20,
29,
30,
31]. Therefore, PYD seems to be an ideal perspective from which to promote values in young people through its practice.
For the assessment of values and the intervention programmes carried out for their development, classic instruments have usually been used, such as, for example, the Rokeach-Value Survey [
32], the Schwartz-Value Survey [
33,
34] or the Personal Values Questionnaire [
35]. Furthermore, there are instruments for the assessment of values in the sport context, such as the Youth Sport Values Questionnaire (YSVQ) [
36,
37], the Spirit of Sport Values scale [
38] or the Sport and Olympic Values Questionnaire [
39]. However, there is a gap in terms of instruments based on the PYD approach.
A scale that can be considered of interest in this context is the Values Scale for Positive Youth Development [
40]. The authors set out to construct a scale with adolescent values as a construct to be studied within the framework of the PYD. The scale was designed for use in school contexts, being in support of the school having a primary role in the moral and socio-emotional education of students, with a view to promoting competences that will enable young people to make their contribution to society and successfully face their personal and professional lives [
40,
41].
The authors carried out a review of the various traditional models and instruments for the assessment of values, such as those mentioned above [
33,
34,
35], in addition to the Values Profile [
42], the Goals Questionnaire for Adolescents [
43] and the Socio-personal Values Questionnaire for Coexistence [
44]. Although most of these instruments were supported by a solid theoretical basis and their use was consolidated within values research, all of them were far from the theoretical approach of assessing values related to the promotion of PYD. Different problems were also encountered, such as being oriented to the study of cultural differences in values, being focused on other specific areas unrelated to PYD, or not having appropriate psychometric properties [
40].
Its proposal, the approach adopted and the appropriate psychometric properties demonstrated by the instrument make its adaptation to sport possible, interesting and of relevant value. Therefore, the aim of this study was to adapt and analyse the measurement properties of the Values Scale for Positive Youth Development in Sport for use in the context of sport in young athletes.
2. Materials and Methods
2.1. Participants
The sample consisted of a total of 599 adolescents (392 boys and 207 girls) aged 11 to 19 years (M = 14.74, SD = 2.40) who were members of different sports clubs in the regions of Alicante, Murcia and Granada (Spain). Athletes competed in organised and official leagues of soccer (42.09%), futsal (18.21%), basketball (29.73%) and handball (9.97%). A total of 50 clubs participated with teams in different categories of competition, from Under-12 (11–12 years) to Under-19 (17–19 years): 19 clubs of soccer, 10 of futsal, 14 of basketball and 7 of handball.
The mean age of starting in the sport was 6.83 years (SD = 2.21), and a mean experience of 5.27 years (SD = 3.11) competing in their sport. The average number of training days per week was 2.95 (SD = 0.88) and 4.91 h (SD = 1.57) of training per week.
2.2. Measures
The Values Scale for Positive Youth Development is a 24-item scale developed by Antolín et al. [
40] that assesses the importance that adolescents attach to a set of values of particular relevance in PYD.
The study of the scale confirmed evidence of validity focused on the dimensionality of the instrument, with a structure of eight first-order factors and three second-order factors. The first-order factors are: Pro-Sociality (importance given to actions of help, collaboration and care for others), Social Commitment (relevance of active participation in the community), Justice and Equality (interest in achieving a socially just and equal world), Responsibility (importance given to personal responsibility and taking responsibility for one’s own actions), Integrity (importance given to acting on the basis of one’s own moral principles), Honesty (valuing sincerity and the communication of the truth), Hedonism (importance given to achieving one’s own pleasure above other goals) and Social Recognition (importance given to being recognised and admired socially). The three second-order factors are: Social Values (Pro-Sociality, Social Commitment and Justice and Equality), Personal Values (Responsibility, Integrity and Honesty), and Individualistic Values (Hedonism and Social Recognition).
The instrument used is a seven-point scale (1: Not at all important; 2: Not very important; 3: Somewhat important; 4: Important; 5: Quite important; 6: Very important; 7: Most important).
The results of the original scale showed the good reliability of all dimensions (Social Values α = 0.89; Personal Values α = 0.89; Individualistic Values α = 0.80; Pro-Sociality α = 0.90; Social Commitment α = 0.90; Justice and Equality α = 0.86; Integrity α = 0.84; Responsibility α = 0.87; Honesty α = 0.87; Hedonism α = 0.84; Social Recognition α = 0.89).
2.3. Procedure
The test adaptation guidelines of the International Test Commission (ITC) [
45] were followed for this study.
The first step, with the aim of obtaining evidence of content validity, was based on an analysis of the questionnaire and its justification by six university professors, from public and private universities in Spain, all of them with PhD degrees. The six experts were contacted because of their significant experience in the fields of education and psychology. Three of the experts were sport psychologists, one was a specialist in sport pedagogy and two were specialists in developmental psychology. After analysing the items and their suitability in terms of wording, and the congruence of each item in each dimension, the terminological adaptation was carried out to adapt them to the sporting context. After discussion and their respective comments, the experts reached consensus on the need for the modification of several items. Item 5, “Belonging to or participating in social organisations” from the Social Commitment factor, was replaced by “Belonging and participating in my team”. Item 6, “Being actively involved in groups, associations or organisations to which I belong” from the same factor, was adapted to “Actively involved in the sports club to which I belong”. Item 11, “Fight against social injustices” from the Justice and Equality factor, was replaced by “Fight against injustices in sport”. Finally, item 12, “Participate in a socially committed group” from Social Commitment, was reworded as “Engage socially with my team”. Furthermore, the heading of the instrument “Please rate on a scale of 1 to 7 how important the following issues are to you” was replaced by “Please rate on a scale of 1 to 7 how important the following issues are to you in sport”.
Once the final draft was completed, the questionnaire was administered to 10 athletes. In order to find out the possible differences in reading and comprehension by age, six boys and four girls were selected from the competition categories established in Spain: three from the Under 12 category (11–12 years), two from the Under 14 category (13–14 years), two from the Under 16 category (15–16 years) and three from the Under-19 category (17–19 years). They read the questionnaire, and all of them confirmed a correct understanding of the items. The final questionnaire is listed in
Appendix A.
Subsequently, contact was made with different sports institutions with which the members of the research team collaborated. The objectives of the study were explained, and their participation was requested. The interested clubs and institutions facilitated contact with the sports coaches, also explaining the research approaches. The coaches provided the athletes with an informed consent form, which they had to give to their parents and return it signed, though only in the case of underage athletes.
The aims of the study, the relevance of their participation, and the confidential treatment of the data obtained were explained to the participants. The questionnaires were administered to each team of athletes before the training sessions and answered individually. Participation was voluntary. The researchers were present during the application of the tests in order to supervise the correct completion of the data and to resolve any doubts that might arise for the players.
2.4. Data Analysis
A screening of the data was carried out to verify the consistency of the responses and the absence of outliers in the variables analysed. IBM SPSS 21 was then used to calculate descriptive statistics.
Given the existence of previous research on the factor structure in the original version [
40], a confirmatory factor analysis (CFA) was carried out using Amos Graphics 21 (IBM Statistics) in order to determine the instrument’s fit and reliability.
To assess the fit of the measurement model, several fit and error indices were calculated. These included: Chi-square (χ2)/degrees of freedom; the goodness-of-fit index (GFI); the adjusted goodness-of-fit index (AGFI); the comparative fit index (CFI); the root mean square error of approximation (RMSEA); standardised root mean square residual (SRMR).
In addition, an analysis of invariance was performed across three nested models to verify the equivalence of the model across different groups. Invariance was assessed using differences in
χ2 tests, following the criteria of Cheung and Rensvold [
46], where differences greater than 0.01 in CFI values indicated a lack of invariance. An analysis was conducted for gender, sport and age. The age groups were based on the WHO recommendations for disaggregation by age groups (10–14, 15–19 years) for the measurement of adolescents on different indicators [
2]. By sport, an analysis was made between soccer, the sport with the highest number of players and participants and the rest of the sports.
Finally, it was decided to calculate the composite reliability index to assess reliability, as this analysis considers the presence of multidimensionality, unlike Cronbach’s alpha [
47]. In terms of interpretation, index values above 0.7 in descriptive contexts or 0.9 in selective tests are considered acceptable [
48].
4. Discussion
The positive youth development (PYD) approach has become increasingly relevant in recent times, with sport being a field of particular interest for the analysis of young people’s inner strengths and the development of positive sporting experiences. Based on the premise that PYD can be a suitable perspective from which to promote values in young people through sport, appropriate and valid instruments are needed for its assessment. Therefore, this study aimed to adapt and analyse the measurement properties of the Values Scale for Positive Youth Development [
40] for its use in the sport context.
The results showed that the scale had adequate measurement properties. Firstly, in terms of construct validity, a good model fit was obtained, with a value of
χ2/df = 2.86, which was between one and three, a criterion considered acceptable [
49]. The different indices analysed also provide adequate data, since the values of the comparative fit index (CFI), goodness-of-fit index (GFI) and adjusted goodness-of-fit index (AGFI) have values equal to or greater than 0.90, and the error indices RMSEA and SMSR are below 0.80, all criteria proposed as satisfactory by different authors [
50,
51,
52,
53]. As for CFA, factor loadings above 0.50 were obtained for all items [
52,
54].
As for reliability, a composite reliability analysis was carried out as it takes into account the presence of multidimensionality [
47]. The values ranged between 0.72 and 0.89, being acceptable when higher than 0.7 [
48]. As previously noted, the original study by Antolín et al. [
40] obtained values between 0.84 and 0.90, although using Cronbach’s alpha, which does not take into account the multidimensionality mentioned above [
48].
An important aspect of the present study was the analysis of invariance, something that was not analysed in the original study [
40]. The results confirm this factorial invariance between the gender, age and sport of athletes.
Therefore, all the results found were in accordance with those confirmed in the original questionnaire. The Antolin et al. [
40] scale has been used in different research studies and contexts, mainly educational, showing good levels of validity and reliability. For example, the instrument has been used in studies on the prevention of bullying at school [
55], and to analyse the relationship and influence between values and the criminalisation of misdemeanours and crimes [
56]. It has also been adapted for use with Argentinian [
57], Chilean [
58] and Peruvian [
59] adolescents, and has served as a basis for the development and validation of other scales [
60,
61]. In sport, we found only one study in which the instrument was used with athletes, specifically with young soccer players [
14]. That study found that Personal Values are related to task orientation and Individualistic Values to ego orientation. Furthermore, the values of Responsibility, Integrity and Honesty predicted task orientation, while Social Recognition and Hedonism predicted ego orientation. Honesty and Responsibility were the main predictors of both task and social cohesion.
The scales assessed through the Values Scale for Positive Youth Development in Sport can be used for the analysis and understanding of important values in young athletes. Social values are related to both good social integration and a positive contribution to the community, which is emphasised in PYD models [
21,
62], and indicate an empathic and prosocial attitude in the adolescent, as well as an interest in collaborating in activities to help others [
41]. Prosocial values are fundamental in sport. Behaviours such as encouraging, congratulating, giving positive feedback or constructive comments to teammates, as well as behaviour towards opponents, such as helping an injured opponent or asking to stop play when an opponent is injured, are examples of positive moral behaviour in sport [
63], which should certainly be promoted.
Personal values imply a high level of personal security and strength to act consistently and follow one’s principles [
40,
41], and therefore, higher scores on this factor will show higher levels of responsibility, integrity and honesty, following their own convictions and moral principles [
41]. In this respect, it is expected that they will be more integrated with their group, they will be more cooperative with their teammates to achieve the team’s objectives and they will seek greater companionship with their teammates [
14]. In addition, previous studies have confirmed the relationship between personal values, attitudes and social behaviours [
64,
65,
66].
Finally, individual values, without representing contra-values, have a less positive meaning than those identified previously [
41]. While the values of hedonism and social recognition have been associated with ego orientation [
14], which has been associated with aggression and unsportsmanlike or antisocial behaviour in sport, it has been suggested that the realm of sport is different in terms of moral exchanges with respect to other aspects of everyday life, where responsibilities are different, and reasoning within a game may lead participants to adopt greater egocentrism and a greater emphasis on victory [
67]. We consider that hedonism, or the pursuit of pleasure or opportunities to have fun [
41], in this age group should not be understood as problematic in the field of sport, as young athletes spend a lot of training and pursue enjoyment through the sport they like.
Limitations and Future Research
However, despite the positive results of the study, we must also note several limitations. Firstly, the process of adaptation and validation of the Values Scale for Positive Adolescent Development in Sport was limited to its administration to Spanish athletes. Spain has its own culture and educational setting, so its use is conditioned to this specific context. Its application was also limited to the study ages covered by the instrument, adolescents between the ages of 11 and 19. Therefore, future research should analyse the properties of the instrument with athletes from different linguistic and cultural contexts. In addition, we must take into account the use of convenience sampling since the participants were selected in a non-random way. Furthermore, the impossibility of carrying out a retest prevented the verification of the constancy of response scores and thus the reliability of stability over time.
Regarding future research lines and practical applications, together with the aforementioned adaptation and validation of the instrument in other countries and languages, we believe that it would be interesting to analyse the values in samples of athletes from individual disciplines, since the participants in this study were all team modalities. Furthermore, the scale presented can be a useful tool to evaluate values in sport in general and also in sports programmes for education in values [
68]. Of particular interest in this area would be the study of additional variables in relation to values and longitudinal and cross-cultural studies [
69].
Furthermore, it is necessary to develop programmes based on sport from the perspective of the PYD, since the experiences carried out have had very positive results in different areas, with positive repercussions on physical, psychological and social levels, and especially for young people who are the most socially vulnerable [
70,
71,
72,
73]. Previous studies have confirmed the important characteristics of youth sports programmes that facilitate prosocial identities [
74].
Finally, we must encourage clubs, sports institutions and coaches to opt for educational models within sport, as opposed to models where only competition is valued, and to make an effort to promote healthy learning environments that encourage young people to internalise positive values, develop adequately in society and help contribute to its improvement [
14,
15].
