In the General introduction (Chapter 1), clear indications of a positive relationship between sports participation and health were presented. However, a number of research gaps were signalled.

Whereas most empirical studies in this field pertain to physical health, fewer studies are available on the relationship between sports participation and psychosocial health or health-related quality of life. Furthermore, the relationship of sports participation with psychosocial health or health-related quality of life has been investigated primarily in adults and adolescents. This relationship has been studied in children to a relatively limited extent. Finally, studies on the relationship between sports participation and psychosocial health or health-related quality of life mostly do not pay attention to several characteristics of sports participation simultaneously. These studies often focus on just one characteristic, for instance on frequency of sports participation or its individual versus team sports characteristic.

These research gaps stimulated the start of a large-scale research project based on the question on whether characteristics of sports participation are associated with psychosocial health and health-related quality of life in children.

From the population of Dutch primary schoolchildren in the fourth and fifth grade approximately 2,300 children have been studied and were involved in the cross-sectional analyses. About 500 children were also involved in the longitudinal analyses. Children’s sports participation, psychosocial health and health-related quality of life (HRQoL) have been examined by means of the Movement and Sports Monitor Questionnaire – Youth Aged 8–12 Years (MSMQ), the Strengths and Difficulties Questionnaire (SDQ) and the KIDSCREEN -52. Children filled in the questionnaires by themselves.

For a quick overview of the research findings described in Chapter 2 to 6, Table 1 displays the crosssectional and/or longitudinal associations that were found between several characteristics of sports participation on the one hand and the three aspects of psychosocial health (internalising problems, externalising problems and prosocial behavior) and the ten dimensions in the three domains of HRQoL (physical, psychological and social domain) on the other.

The general conclusion based on Table 1 is that for children, a number of characteristics of sports participation are associated with both (aspects of) psychosocial health and (dimensions of) HRQoL.

fewer internalising problems and better prosocial behaviour and only to a very limited extent associated with fewer externalising problems in children. The associations of membership of a sports club and frequency of sports participation with fewer internalising problems are for boys more prominent than for girls. For girls, the association of frequency of sports participation with better prosocial behaviour is more pronounced.

The intermediate constructs ‘sports self-concept’ and ‘self-esteem’ may help to clarify the associations of membership of a sports club and higher frequency of sports participation with fewer internalising problems. It is suggested that a more positive sports self-concept is beneficial for a child’s self-esteem (Bowker, 2006; Findlay & Coplan, 2008; Lee & Stone, 2012), which in turn might result in stronger resilience against internalizing problems (Bowker, Gadbois, & Cornock, 2003; Slutzky & Simpkins, 2009). However, we cannot rule out the possibility that higher frequency of par ticipation in sports activities is not a cause but a consequence of having a better self-concept and higher self-esteem or that the relationship may be bi-directional (Da Silva et al., 2012; Vella, Swann, Allen, Schweickle, & Magee, 2017).

The finding that frequency of sports participation (within the group of sports club members) was not associated with externalising problems might be explained by means of the intermediate concept of effortful control. This concept can be defined as the ‘ability to willfully or voluntarily inhibit, activate, or change (modulate) attention and behavior, as well as executive functioning tasks of planning, detecting errors, and integrating information relevant to selecting behavior’ (Eisenberg, Smith, & Spinrad, 2004, p. 263). Externalizing problems may be considered a consequence of a lack of effortful control (Eisenberg et al., 2001). A person’s effortful control is largely biologically rooted and relatively stable across time and contexts (Bates, Schermerhorn, & Petersen, 2012; Eisenberg et al., 2004), mainly evolving between the ages of 2 and 7 (Schermerhorn et al., 2013). The children in our sample, who were aged between 10 and 12 years, had probably already achieved such stability in their effortful control, such that this ability was little influenced by a higher frequency of sports participation. An explanation for the association observed between membership of a sports club and less externalising problems could be that non-athletes already have externalizing problems that prevent them from joining a sports club. Involvement in a sports club requires a child to obey the instructions of a supervisor or coach (Larson, 2000). Perhaps children with more externalizing problems are less willing to accept rules and authority, and, therefore, would be less likely to participate in a sports club.

(6)

to developing and sustaining adequate prosocial behaviour. A reverse explanation is, however, also possible. Children with poor prosocial behaviour may not become or stay a member of a sports club because they often have many behavioural problems (Denault & Déry, 2015). As indicated in the previous paragraph, many behavioural problems in combination with poor prosocial behaviour may cause that these children are not willing to stick to agreements and to behave according rules.

The finding that membership of a sports club and higher frequency of sports participation are more prominently associated with fewer internalising problems for boys than for girls is in line with previous studies. Ahn and Fedewa (2011) and Molinuevo, Bonillo, Pardo, Doval, and Torrubia (2010)also reported that boys had greater psycho-logical benefits from sports than girls. An ex planation may be that, in general, boys derive more self-esteem from success in sports activities than girls (Bowker, 2006; Daley, 2002). Bowker (2006)reported that satisfaction with physical competence (skills, fitness) influences a boy’s self-esteem, whereas satisfaction with physical appearance (body, weight) was of more significance for most girls. Furthermore, Chalabaev, Sarrazin, Fontayne, Boiché, and Clément-Guillotin (2013) and Plaza, Boiché, Brunel, and Ruchaud (2016)argued that boys and girls are susceptible to stereotype effects. Because sports participation is still largely considered to be a male activity in Western society, the impact of sports partici pation on one’s self-esteem varies by sex (Capranica et al., 2013; Deaner et al., 2012; Eagleman, 2015).

The more pronounced associations between higher frequency of sports participation and better prosocial behaviour for girls could be due to a difference between the sexes in how aggression and empathy are expressed during sports. Girls behave less aggressively than boys during sports activities because of both complex social and cultural expectations and the physical characteristics of boys and girls (Coulomb‐Cabagno & Rascle, 2006; Stanger, Kavussanu, & Ring, 2017). Stanger et al. (2017) found that men have more aggressive sports attitudes than women. Women have an attitude to sports which is characterized more by empathy, which tends to prevent them from acting aggressively towards others (Kavussanu, Stanger, & Boardley, 2013) and is, therefore, conducive to the development of prosocial behaviour.

A second conclusion is that with respect to HRQoL, membership of a sports club and higher frequency of sports participation are largely associated with a better HRQoL for the physical domain, to a slightly lesser extent with a better HRQoL for social domain, and to a limited extent with a better HRQoL in the psychological domain.

physical condition (Boyle, Jones, & Walters, 2010; Morales et al., 2013), which in turn results in higher physical well-being (Borras, Vidal, Ponseti, Cantallops, & Palou, 2011; Gu, Chang, & Solmon, 2016). Furthermore, the ‘feel-good’ effect of performing sports activities (Biddle, Mutrie, & Gorely 2015), which is expressed in, amongst others, a better subjective vitality refers to feeling alive and energetic after sports participation and occurs after at least moderate active sports participation (Reed & Buck, 2009).

With respect to the social domain, the association of membership of a sports club and higher frequency of sports participation with better HRQoL does suggest that organised sports activities provide possibilities for children to interact with friends and peers (Howie, Lukacs, Pastor, Reuben, & Mendola, 2010). These interactions facilitate positive social experiences (Holt, Tamminen, Tink, & Black, 2009; Pierce, Gould, & Camiré, 2017) and acquiring better social skills leading to a more favourable HRQoL (Breslin et al., 2012; Chen et al., 2014). Contrary to some investigators who reported negative effects of sports participation (Missiuna et al., 2014; Piek, Barrett, Allen, Jones, & Louise, 2005), our research findings are positive in the social domain. However, one could argue that children who have difficulties to engage in positive behaviours towards peers or stand at risk of being bullied might refrain from becoming a member of a sports club (Jankauskiene, Kardelis, Sukys, & Kardeliene, 2008).

Regarding the psychological domain, an explanation for the association of higher frequency of sports participation with better HRQoL might be that high sports-active children fulfil basic psychological needs for autonomy, competence and relatedness by spending several days per week at a sports club (Teixeira, Carraça, Markland, Silva, & Ryan, 2012). Furthermore, high or moderate sports-active children have the possibility to develop better motor skills, which in turn contributes to a positive sports self-perception (Babic et al., 2014; Balish, McLaren, Rainham, & Blanchard, 2014; Liu, Wu, & Ming, 2015; Robinson et al., 2015). Finally, the ‘feel-good’ effect of high or moderate active sports participation gives, besides benefits in the physical domain, also a pleasant mood and joy in the psychological domain (Reed & Buck, 2009).

Finally, a third more specific conclusion in the light of the research question is that contrary to membership of a sports club and frequency of sports particpation, the kind of sport(s) in which a child participates (i.e., indoor versus outdoor sports, individual versus teams sports, involvement in competition or not, and contact versus non-contact sports) seems to be of minor importance. In the present study, only a very limited number of associations with psychosocial health and HRQoL were found for the characteristics ‘performing indoor versus outdoor sports’ and ‘performing individual versus team sports’.

(8)

some studies in the field of outdoor exercise. Barton, Bragg, Wood, and Pretty (2016) observed that being active outdoors was associated with less depressive feelings in adults. An explanation for this might be that being outdoors has by itself a beneficial influence on someone’s brain (Mantler & Logan, 2015) and this, added with the effect of sports activity, could explain the positive influence of outdoor sports on mood, resulting in less depressive feelings (Barton et al., 2016). Another explanation may be that being active outdoor gives more opportunity to sunlight exposure (Sarris, O’Neil, Coulson, Schweitzer, & Berk, 2014), which might enhance vitamin D levels (Föcker et al., 2017). Although the results of studies in adults are inconsistent (Sarris et al., 2014), there are indications that low vitamin D levels are associated with depressed mood in children (Föcker et al., 2017).

The present study shows very limited associations between performing individual versus team sports with psychosocial health and HRQoL. An explanation might be that the distinction between individual and team sports is not that straightforward. Children participating in individual sports usually train together in groups just like children participating in team sports and, therefore, largely share the same group processes as team athletes (Donkers, Martin, & Evans, 2016). The positive effects of being a member of a group on psychosocial health or HRQoL (Vella, Magee, & Cliff, 2015) might occur not only in children performing team sports but also in children performing individual sports.

Additional analyses on the relationship between sports participation and HRQoL

In the analyses presented thus far, the relationship between a child’s sports participation and his or her HRQoL was analysed without taking the child’s psychosocial health into consideration. However, it is theoretically plausible that psychosocial health is a mediator and/or moderator in the relationship between sports participation and HRQoL (Otto et al., 2017; Ravens-Sieberer et al., 2008). This issue will be investigated below by some additional analyses that were conducted in order to shed more light on the interplay between our three key study outcomes.

METHODS

(9)

The mediation effect of psychosocial health was determined by calculating the percentage difference between the regression coefficient of the total effect and the regression coefficient of the direct effect (Rijnhart, Twisk, Chinapaw, de Boer, & Heymans, 2017). These additional analyses were controlled for gender, BMI, age, SES and household composition as covariates, as was the case with the analyses presented in Chapters 2 to 6.

The following procedure was applied. First, we investigated whether the total effect (path C) of sports participation in the relationship with HRQoL was significant. Subsequently, we determined the direct effect (path C’) of sports participation in the relationship with HRQoL by controlling for psychosocial health as a potential mediator. Finally, we assessed the percentage mediation by psychosocial health (1-(C’/C)). In addition to its mediator role, psychosocial health can also be a moderator. The moderating effect (also known as effect modification) of psychosocial health was analysed by adding the interaction term between sports participation and psychosocial health to the model to analyse the relationship between sports participation and HRQoL. When the interaction term is significant in this relationship, than significant moderation is demonstrated. The sign of the interaction term, positive or negative, reflects the stimulating or inhibiting effect of psychosocial health in the relationship between sports participation and HRQoL (Twisk, 2010).

The mediation and moderation analyses were restricted in four respects. First, the analyses whether psychosocial health is a mediator and/or moderator in the relationship between sports participation and HRQoL were based on cross-sectional data. The number of cases in the cross-sectional sample is much larger than the one in the longitudinal sample and thus offers better possibilities to establish possible associations with respect

Second, in the mediation analyses, we only paid attention to significant cross-sectional associations between characteristics of sports participation and dimensions of HRQoL. These are the cross-sectional associations presented in Chapter 5 of this thesis. Although the restriction to significant associations between sports participation and HRQoL was not necessary to establish possible mediation by psychosocial health (Rijnhart et al., 2017), it was done to limit the number of analyses.

Third, the mediation and moderation analyses focused on two characteristics of sports participation, namely membership of a sports club and frequency of sports participation since these two characteristics showed the largest number of associations with different dimensions of HRQoL (see Table 1 above).

Fourth, with respect to psychosocial health, only internalising problems and prosocial behaviour were taken into consideration in the mediation analyses. Because only a very small number of significant associations between sports participation and externalising problems were found (as has been noted in the first part of this chapter), externalising problems cannot be a mediator of any importance in the relationship between sports participation and HRQoL. However, it is not inconceivable that externalizing problems is a moderator in this relationship. Therefore, in contrast to the mediation analyses, the moderation analyses took all three aspects of psychosocial health into account and paid also attention to externalising problems.

Table 3 shows the mediation effect of prosocial behaviour in the associations of membership of a sports club with HRQoL.

As has been shown in Tables 2 and 3, the association between membership of a sports club and the dimension in the physical domain of HRQoL is more strongly mediated by internalising problems (12%) than by prosocial behaviour (6%). The same is observed for the associations with respect to one out of three dimensions in the psychological domain (40% versus 18%) and five out of six dimensions in the social domain (14-47% versus 11-22%) of HRQoL.

Frequency of sports participation

Tables 4 and 5 show the results of the mediation analyses regarding frequency of sports participation and HRQoL. The tables present only information about the HRQoL dimensions for which significant associations with frequency of sports participation were observed.

As can be seen from Table 4 and 5, the associations between frequency of sports participation and five out of ten dimensions of HRQoL were stronger mediated by internalising problems than by prosocial behaviour.

Moderation (effect modification)

The last additional analyses presented here focus on possible moderation by internalising problems, externalising problems and prosocial behaviour in the associations between membership of a sports club or frequency of sports participation and the ten HRQoL dimensions. For a brief and handy overview of the results, Table 6 presents only information about the HRQoL dimensions for which significant moderation was found.

As can be seen in Table 6, with respect to internalising problems, there was no significant moderation with the HRQoL dimensions.

With regard to externalising problems, significant moderation was found in the associations between frequency of sports participation and the HRQoL dimensions ‘physical well-being’, ‘social acceptance (bullying)’ and ‘school environment’. On the one hand, children with more externalising problems seem to profit less from participating more frequently in sports activities with respect to the HRQoL domain ‘physical well-being’. One may argue that since these children often display hyperactive behaviour, sporting more frequently probably does not give them the extra ‘feel good’-effect that children with fewer externalizing problems get from exercising more often. On the other hand, children with more externalizing problems seem to benefit more from exercising with a higher frequency with respect to the dimensions ‘social acceptance (bullying)’ and ‘school environment’. A possible explanation for this could be that children with more externalising problem have less effortful control which prevents them from behaving adequately in relation to peers and at school (Denault & Déry, 2015). Due to their behavioural problems a substantial frequency of sports participation might be necessary to acquire social skills needed for resisting the bully and feeling at ease at school, resulting in higher satisfaction and joy with regard to these dimensions of their HRQoL.

With respect to prosocial behaviour, there was significant moderation in the association between frequency of sports participation and the HRQoL dimension ‘autonomy’. In children with better prosocial behaviour frequent sports participation and autonomy were more strongly associated than in children with less prosocial behaviour. This might be explained from the assumption that people, including children, can only feel free and autonomous when they behave friendly and nice towards peers. Good prosocial behaviour might be a condition for experiencing freedom and autonomy (cf. Caprara & Steca, 2005).

RELEVANCE FOR PRACTITIONERS

Based on the results of the present study, it seems that sports participation is beneficial for a child’s psychosocial health and HRQoL. In particular, being member of a sports club and performing sports activities with a moderate or high frequency are associated with both a better psychosocial health and a better HRQoL. This also applies, albeit to a small extent, to performing outdoor sports (contrary to indoor sports).

The relationship between a child’s sports participation and his or her HRQoL seems to be mediated substantially by psychosocial health, which means that this relationship occurs to a considerable degree through psychosocial health. Furthermore, the relationship between a child’s sports participation and his or her HRQoL seems to be moderated to a limited extent by the child’s psychosocial health, which means that this relationship is mostly independent of the extent to which a child had better or worse psychosocial health.

What are the practical implications of these findings and which recommendations can be made?

Practical implications

A first implication is that children should be encouraged to participate frequently in any kind of organized sports activities. Sports participation seems to be beneficial for a child’s psychosocial health and his or her HRQoL. Frequency of sports participation appears thereby to be much more relevant for a child’s psychosocial health and his or her HRQoL than the kind of sport(s) in which the child participates. Therefore, the choice for a sport that the child can and likes to do with a relatively high frequency is more important than the choice for a certain type of sport.

A second implication is that the promotion of sports participation aimed at fostering children’s HRQoL should not only be limited to children with poor psychosocial health. Sports participation seems to be beneficial for a child’s HRQoL, regardless the level of his or her psychosocial health. The associations observed between sports participation and HRQoL are moderated by a child’s psychosocial health only to a small extent.

A final implication is that a child’s HRQoL may be improved by sports activities that are conducive to the child’s psychosocial health. Most of the observed associations between sports participation and HRQoL are mediated by the child’s psychosocial health. This implies that sports activities that are profitable for a child’s psychosocial health may also be beneficial for his or her HRQoL.

Recommendations

How can children be stimulated to participate in any kind of organised sports activities on a regular base? Focusing on the context in which the children of the present study were investigated, i.e., primary schools, a number of recommendations can be made.

(16)

Second, primary schools could stimulate students to participate in the activities of a ‘sports mix organisation’ or ‘club extra’. Such organisations, which are found incidentally in the Netherlands, provide sports and play activities for children who are currently not able to participate in the activities of regular sports clubs due to motor and/or psychosocial problems. The sports mix activities are adapted to the level of these children, both in terms of their motor skills as well as in terms of their psychosocial development. During the sports mix course, which can have a varying duration for each child, children get the chance to develop further motorically and/or psychosocially until they are sufficiently equipped to participate in regular sports club activities. This way, children with motor and/or psychosocial problems may be empowered to make a switch to a regular sports club in the near future (De Meij, Chin A Paw, Kremers, Jurg, & van Mechelen, 2010; Van de Geer, 2005).

Third, because the proximity of a school to sport clubs does not seem to provide an advantage with regard to sports participation (Pot & Van Hilvoorde, 2013), primary schools should make greater use of the possibility to appoint an official who is partly employed by the primary school and partly working for one or more sports clubs in the immediate environment of the school. This linking pin construction, performed by a so-called ‘combination officer’, is quite common in the Netherlands and is conducive to the mutual coordination between physical education activities at school and the activities of the sports clubs, which may children stimulate to become member of a sports club (De Meester, Aelterman, Cardon, De Bourdeaudhuij, & Haerens, 2014; Vereniging Sport en Gemeenten, 2008).

Finally, elementary schools, ‘sports mix organisations’ and sports clubs could make use of the services of psychomotor therapists. These professionals can stimulate and guide children with behavioural problems in participating in sports activities. They are able to do so because of their expertise in both the field of psychosocial health and the field of human movement. This dual expertise makes them suited for helping children with mental and/or motor problems to take part in organised sports activities (NVPMT, 2009; Probst, Van Damme, & Vancampfort, 2017; Emck, Van Damme, & De Lange, in preparation).

FUTURE RESEARCH

(17)

Stavrakakis, De Jonge, Ormel, & Oldehinkel, 2012; Vella et al., 2017), intervention-based research can provide more insight into mechanisms and processes behind the observed associations between sports participation and psychosocial health/HRQoL.

Furthermore, future research might take more characteristics of sports participation into consideration. For example, the intensity of sports activities could be taken into account. The literature provides indications that the intensity of sports participation has a relationship with a person’s psychosocial health and HRQoL (Breslin et al., 2012; Brown et al., 2004; Wu et al., 2017). In the present study, the intensity of sports activities could not be properly measured, because we used self-report questionnaires. A more valid and reliable method is to have children wear an accelerometer during their sports activities.
