Introduction
Regularly practising physical activity is an ideal, healthy way to obtain physical, psychological, and social benefits in the adolescent maturation process (Castillo, Balaguer, & García-Mérita, 2007). The adolescent period is when the maturational development of perfectionism has been identified (Damian, Stoeber, Negru, & Băban, 2013) and it has been recognised as an important stage for the acquisition of behaviour patterns and habits relating to health, such as systematic physical activity transferred to everyday life situations, cognitive maturation, and the perception of well-being in later developmental periods (Codina & Pestana, 2016; González, Garcés de los Fayos, & García del Castillo, 2011).
As the intensity of physical activity increases, individuals develop strategies and competences to cope with the circumstances surrounding them. Interacting with significant others, learning, maturing, and experimenting in their social contexts give the adolescent resources to react more or less effectively, shaping and constructing the functionality-dysfunctionality of the physical-biological condition and the psychological response linked to executive functions (Martín-Martínez, Chirosa, Reigal, Hernández-Mendo, Juárez, & Guisado, 2015; Wong, Lau, Wan, Cheung, Hui, & Mok, 2013), balanced negative emotional states (Brand et al., 2017), lower levels of anxiety (Olmedilla, Ortega, & Candel, 2010), and better psycho-social and personal maturation processes (Chaddock, Pontiflex, Hillman, & Kramer, 2011; González & Portolés, 2014; Ramírez, Vinaccia, & Suárez, 2004), and consequently, the personal characteristics of the performance in question in a specific context.
Given the multidimensional conception of perfectionism in contexts of practice of physical-sporting activity (Madigan, Stoeber, & Passfield, 2017; Stumpf & Parker, 2000), the last two decades have seen a noticeable increase in studies that have tried to determine the association between its different dimensions, and the cognitive, emotional, and/or behavioural aspects that motivate the practice of physical activity (Hill, Hall, Appleton, & Kozub, 2008; Longbottom, Grove, & Dimmock, 2010). PA is regarded as functional when it is positively (and as adaptive efforts) associated with aspects such as self-efficacy, self-confidence, planning, and persistence in the physical activity (Moore et al., 2018), and dysfunctional when linked to uncertainty regarding execution, fear of failure, anxiety, and avoiding physical activity (Flett & Hewitt, 2005). Accordingly, the relationship between efforts to achieve sporting objectives (Biddle, Wang, Kavussanu, & Spray, 2003; Roberts, Treasure, & Conroy, 2007) and how they are proposed, set out, and reacted to psychologically in order to achieve them (Hill & Curran, 2016; Muñoz & González, 2017; Stoeber, Otto, Pescheck, Becker, & Stoll, 2007; Stoeber, Stoll, Pescheck, & Otto, 2008; Taylor, Papay, Webb, & Reeve, 2016) has become one of the most debated topics in scientific literature at present.
The response to stress in sporting practise is regarded as adaptive when it manifests itself in a constant form both in frequency and duration (Bjorklund, Blasi, & Ellis, 2015) and as functional when it appears as an element that facilitates action (Monasterio et al., 2016). In this second case, a functional process is recognised because it creates the activation for adjusting to new conditions, and constructs subjective perceptions of psychological well-being and distress (Neil, Hanton, Mellalieu, & Fletcher, 2011) and so of physical and mental health. Therefore, it can be claimed that the combination of processes that enable the functionality of individuals in their interaction with the environment will allow adaptive responses in terms of repeated and habituated behaviour (this is why a good comprehension of the utility of effort in adolescence enables the adapted behaviour of using physical exercise as part of one's adult lifestyle).
Based on this, humans awaken and create resources that set off functional processes as anticipatory and protective alerts in the face of situations of negative evaluation of dangers, risks to one's own life or one's physical, health, and social status (Dunkley, Berg, & Zuroff, 2012; González & González-Reyes, 2017; Taylor et al., 2016) or about opportunities and strengths that the consciousness can only perceive in this facilitating state of alert (Hill, Witcher, Gotwals, & Leyland, 2015). For this reason, it is important to be able to interpret and mentally comprehend the activation (physical, physiological, and psychological) caused by the intensity of the practice of physical activity, and how this comprehension-or lack of it-creates adaptive changes (that facilitate functionality) or maladaptive reactions (that cause blocks or dysfunctionality) (see Figure 1). Perceived stress is one of these responses that is not based on the qualities of the stimulus, but rather on the perception of capacities to self-regulate personal fa ctors and the perception-interpretation of contextual factors.
Practising physical exercise and practising sport are thought to differ in how the subjects experience the scope of their objectives. Sport (in a competitive system with governing bodies) presupposes the need for comparative efforts between the best and worst athletes, who are subject to classification and even social valuation (e.g. of the champion). Physical exercise, however, involves physical effort, through play, without it necessarily having to create high demands or a competitive requirement. Accordingly, when people practise physical exercise, and depending on the involvement of more or less perfectionist mental schemas, the perception of stress elements will allow an active response to correct identification of one's own emotions, providing a functional response that leads to higher psychological well-being and positive affective states (González et al., 2011; Stults-Kolehmainen & Sinha, 2014), thus favouring mental health, equilibrium, and quality of the experience in sporting practice (Hamilton, Foster, & Richards, 2016). On the other hand, a passive response (or an active response tending towards dysfunctionality) characterised by negative emotions, high physiological and emotional activation, or depressive episodes that cause mental blocks and exhaustion, will favour the perception of loss of control when faced with certain situations (Nicholls, Levy, Carson, Thompson, & Perry, 2016), resulting in psychological distress) and loss of quality in the task being performed (Muñoz & González, 2017; Pastor, Balaguer, Pons, & García-Merita, 2003).
Adolescence coincides with a turbulent developmental stage, combining attention to needs in the academic setting (exams, personal and family expectations, etc.) (May & Casazza, 2012), life changes that entail new and different social relationships (peer groups or social settings, independence from the family, etc.) (Laible, Carlo, Davis, & Karahuta, 2016), establishing career (Negru-Subtirica & Pop, 2016), and romantic orientations (Spinrad & Gal, 2018), maintaining a continual physical or aesthetic condition (Fernández-Bustos, González-Martí, Contreras, & Cuevas, 2015), and sometimes practising high-performance competitive sport (Molina, Chorot, Valiente, & Sandín, 2014). Inevitably, everything set out here reveals the vulnerability of the well-being and distress process, and so consistent regulation of stress as a learned process involving interaction between the individual and her environment will make it possible to construct facilitating resources for a functional response to it (Breeding and Anshel, 2015; Lizmore, Dunn, & Dunn, 2017).
In view of what has been proposed, it is interesting to know how in adolescents perfectionist beliefs are “functionalised” along with normal and balanced elements to construct psychosocial resources. This work sets out to analyse the modulating role of physical activity as a facilitator of functional patterns in the stress response among adolescents. The initial hypotheses suggest that adolescents who perform more moderate physical activity will show higher profiles for perfectionism, and that with higher levels of PA, adolescents will show higher dysfunctional patterns, and will have fewer resources for perceiving stress.
Method
Participants
This work uses, as a quantitative and non-random methodology, a cross-sectional, correlational, and predictive design. The sample comprises 365 adolescents from different communities in the provinces of Madrid and Granada (Spain), aged between 13 and 17 (M= 15.02; SD= 1.36). Their age distribution is: 13 (29%), 14 (14.8%), 15 (14.8%), 16 (18.9%), and 17 (22.5%). Of the participants, 182 were male (49.86%) and 183 female (50.14%). They were from families with a medium-high socioeconomic level.
Instruments
Ad-hoc sociodemographic and sport frequency questionnaire This is a self-administered questionnaire comprising four items. It was prepared by the researchers based on the WHO's PAQ-A methodology. The questionnaire compiles information relating to the intensity of subjects' PA (non-vigorous (low, moderate) and vigorous) and how frequently they play sports (sport played and number of days). The answer format takes into account personal variables regarding age, gender, studies, and socioeconomic level relating to the information being studied.
Frost Multidimensional Perfectionism Scale (FMPS; Frost, Marten, Lahart, & Rosenblate, 1990, version adapted for use with Spanish populations by Carrasco, Belloch, & Perpiñá, 2010). The items are distributed across two second-order dimensions, made up of second-order indicators: functional perfectionism (achievement expectations and organisation) and dysfunctional perfectionism (fear of mistakes and parental influences). The scale comprises 35 items, measured on a five point Likert scale, from 1 (“strongly agree”) to 5 (“strongly disagree”). Regarding the internal consistency of this sample, α values of between .89 (organisation) and .82 (paternal influence) were found. These are very similar to those from the other studies performed.
Perceived Stress Scale (PSS; Cohen, Kamarck, & Mermelstein, 1983, version adapted for use with Spanish populations by Remor & Carrobles, 2001). This comprises 14 items (7 positively phrased and 7 negatively phrased), measured on a Likert scale from 0 (“never”) to 4 (“very often”), giving a single indicator called perceived stress, where the higher the figure, the greater the perception of stress, with a Cronbach's alpha of .81 for internal consistency.
Procedure
To carry out this research, sport and education centres were contacted to request permission from their management (coaches and teachers in charge of the centres) and the aim of the research and the method for obtaining and protecting data were explained to them. They were given an informed consent protocol which the adolescents had to give to their legal guardians to complete, in accordance with the Helsinki regulations. Once permission had been obtained, the contacted centres were visited again and the adolescents who had given accepted informed consent were asked to participate voluntarily in the study and were informed of the confidentiality and anonymity of the data. At this point, the questionnaires were administered collectively in the classroom for a period of 30 minutes without interruption. A researcher was present at all times during data collection to ensure possible contaminating distractions were controlled and solve any doubts if required.
Data analysis
The codification and processing of the data was done using the SPSS 22.0 for Windows statistics package. Analyses of the internal reliability of the measurements used were performed (Cronbach's alpha), as well as descriptive analysis (mean, standard deviation), the normal distribution was checked for (Kolmogorov-Smirnov), and comparative measurements were performed (t test for differences in means between groups and Cohen's d for effect size). For the predictive relationships, multiple stepwise regression analyses and moderated mediation analyses were performed (VIndependent: perfectionism; VDependent: perception of stress; VModerate practising physical activity) using the PROCESS program.
Results
Differential analysis
The frequency of physical activity by gender of participants (Table 1), shows that girls practise more PANonVigorous than boys, while boys practise more PAVigorous. Furthermore, it is apparent that as their age increases, girls practise less PA, while boys practise less PANonVigorous and more PAVigorous.
The means for the indicators of perfectionism and perceived stress as a function of sporting frequency (non-vigorous or vigorous) (Table 2) show, with a large effect size, that the higher the more frequent physical activity is, the higher the mean scores for all indicators of perfectionism are, These are significant in the case of organisation (t(363.2) = -2.72; p= .00), personal standards (t(363.2) = -3.73; p= .00), and fear of mistakes (t(363.2) = -14.31; p= .02).
Predictive analyses
The predictive analysis constructs two stress perception models (Table 3). The first one (F (125.1)= 27.44; p< .00), with an explained variance of 38%, shows that only an increase in perceived fear of mistakes make perceived stress increase. The second one (F (124.2)= 17.65; p< .00), which has an explained variation of 22%, shows that the perception of stress in the group of adolescents is predictive of an increase in age, greater intensity in practice of PA, and the perception of fear of making mistakes, and does not create any predictive relationship with the functional indicators of perfectionism.
In the same way, two other predictive models for intensity of PA practice were established. The first one (F (125.1)= 19.81; p< .01), with an explained variation of 33%, reflects the fact that setting high personal standards positively predicts an increase in intensity of practice of PA. A second model (F (124,2)= 21.62; p< .00) predicts with a variance of 24% that the combination of increased personal standards and reduced fear of making mistakes predicts an increase in the intensity of practise of physical activity in adolescents.
Running the moderated analysis shows that adaptive perfectionism (personal standards and organisation) along with practice of PANonVigorous establishes an inverse predictive relationship with high perceptions of stress. With PAModerate the perception of stress becomes accustomed and maintained (Figure 2), so that perfectionism only responds functionally with lower stress indicators being perceived when the practice is daily, of normal and non-vigorous intensity.
Applying the moderator analysis shows that maladaptive perfectionism (fear of mistakes and concern over actions) in combination with increased practise of physical activity (PAModerate and PAVigorous) establishes relationships with high perceptions of stress (Figure 3). In this way, maladaptive perfectionism responds dysfunctionally resulting in a higher perception of stress indicators when the sample of adolescents analysed reports an increase in the intensity of their PA practice.
As booth images show, there are no significant levels of predictability when the intensity is PALow, and so this variable has been considered in combination with non-vigorous PA.
Discussion
This work sets out to describe perfectionist patterns of behaviour along with intensity of PA practice, establishing their relationship for maintaining functional or dysfunctional levels of perceived stress in a sample of adolescents.
The description of the sample showed that regular practice of PA in adolescence falls gradually as adolescence progresses, despite the annual recommendations of the WHO. This negative trend in frequency of PA in higher academic years (also corresponding to age) coincides with the point in life where PA stops being obligatory or significant in the curriculum, and has previously been identified in studies that have shown similar results in adolescent populations in Spain (Codina & Pestana, 2016), anglosajon world (Peetz, Buehler, & Britten, 2011), and South America (Bolaños, Cornejo, Rocha, Vitoria, Flores, & Campos, 2016). Another important piece of data is the difference in practice of PA by gender, with boys being more involved in vigorous PA, as shown in other previous studies (González & Portolés, 2014; Práxedes, Sevil, Moreno, Del Villar, & García-González, 2016).
The first starting hypothesis suggests that adolescents with the highest demands in sporting practice will show higher indicators of perfectionism. The comparison of means between the study variables shows significant differences in the more functional indicators of perfectionism (organisation and personal standards) in favour of those who report PAvigorous. As for dysfunctional indicators of perfectionism (parental expectations and fear of mistakes), a tendency to increase with medium or higher intensity of PA is apparent, as is a positive and significant relationship with perceived stress. These results agree with others identified (Gotwals, Stoeber, Dunn, & Stoll., 2012; McMahon et al., 2017), and they are associated with the appearance of psychological risks deriving from exercise that is excessive in duration and intensity (PAvigorous). They also agree with studies that state they focus on the negative evaluation of resources for facing the demands of the social context surrounding this activity (Schwebel, Smith, & Smoll, 2016; Taylor et al., 2016).
Results of the predictive analysis show that practising PA is positively related with the mental establishment of personal standards and with reduced fear of mistakes. Accordingly, when adolescents increase the intensity of practice of PA, it is regarded as very important to train or educate the adolescents so that they set certain balanced standards of requirement for themselves and develop beliefs for to increase capacities and that allow to reduce fear of mistakes (demystifying mistakes). Results obtained suggest that intensifying PA practice means that adolescents with maladaptive perfectionist profiles identify higher significant levels of perceived stress, thus provoking a positive stress stimulus (Molina et al., 2014) and a psychosocial resource for the dysfunctional response in the face of the response in question (Cairney, Kwan, Veldhuizen, & Faulkner, 2014; Remor & Pérez-Llantada, 2007). Significant relevance is only found in adolescents with adaptive perfectionist profiles when the intensity of PA is vigorous, given that the high standards mentioned above are also associated with higher demands in sporting activities.
In contrast, maintaining moderate intensity of PA (brisk walking, dancing, active participation in games and sports, walking with pets, carrying moderate loads of under 20 kg) shows a direct and significant relationship with the more adaptive processes of the perfectionist pattern, with the result that this process, which is between habit and belief, facilitates the regulatory and functional perception of the stress response.
The second of the hypotheses states that as levels of intensity of practice of PA increase, adolescents will show greater dysfunctional patterns and have fewer resources for perceiving stress. The results obtained confirm that those subjects with tendencies towards fear of making mistakes and a perception of pressure from parental influences and expectations report a higher perception of the stress response as the intensity of PA increases, with something similar also being shown by other studies with samples of young sportspeople, both competitive (Gustafsson, Hill, Stenling, & Wagnsson, 2016) and non-competitive (Franche & Gaudreau, 2016).
Conclusions
This work has attempted to establish how relevant is the construction of perfectionist beliefs about tasks (in this case sporting ones) in adolescence. The aim of this was to test whether these beliefs behave functionally or dysfunctionally when performing the tasks (that is, they are not just configured mentally also corroborated when put into practice). A large sample of Spanish adolescents was contacted in order to administer surveys to them and it was found that for adolescents who focus on their concerns and the perception of external pressures, there is an increase in the perception of stress both through practising PAVigorous and PAModerate. In contrast, for adolescents with perfectionist patterns built on the basis of balanced requirements and ordered planning, practising PAModerate allows for the functional response (perceiving less stress), while practising PALow has an inverse predictive relationship on the increased perception of stress. These results show that PA practice which is unbalanced in frequency and intensity (PAVigorous) does not significantly result in an improvement in stress regulation when adolescents put into play their more functional resources on the beliefs about how to act.
Having shown the importance of practising physical activity for indicators of perfectionism and perceived stress, future research with other age cohorts, in other socioeconomic contexts, using tests that are better understood in the adolescent period and combining other methodologies such as collecting information qualitatively through focus groups or in-depth interviews is advisable. Similarly, taking into account other aspects that affect the construction of perfectionist beliefs (e.g. personality traits, coping resources, perceived social support, etc.), would make it possible to examine in greater depth how many of these schema are associated with ongoing sporting practice, their functional-dysfunctional experiences and responses, or to resistance to effort, including giving up sport. Similarly, establishing experimental and pseudo-experimental methodologies that allow longitudinal continuity and continuity over time in the measurements will make it possible to explain whether the answers obtained here are repeated, whether they are typical of an era or specific events restricted to adolescence, or whether they change with the passage of time and maturation or new experiences.
The data provided, should be considered in light of the existence of limitations that did not allow access to a broader sample of adolescents or continuing the measurements in another later measurement (T2). Despite these limitations, the research makes an important contribution to understanding psychological responses in adolescents relating to their sporting practice and their beliefs about the levels of requirement of their pursuits and their personal resources, a topic that has been of great importance in the last two decades in sporting, educational, and clinical settings. Evaluating this type of variable makes it possible to design preventative health programmes and/or programmes for stimulating coping strategies that, maintained over time, become more adaptive. It also enables training in cognitive and emotional self-regulation skills, learning about psychological resources (e.g. motivational counselling or self-talk), which combined with healthy habits such as practising balanced PA helps confront stressful situations effectively and functionally.
