Feasibility and preliminary effects of a peer-led motivationally-embellished workplace walking intervention: A pilot cluster randomized trial (the START trial).

Walking interventions can be effective in increasing physical activity amongst physically inactive employees. However, despite their promising potential regarding sustainability and scalability, peer-led workplace walking interventions have not been tested. We evaluated a peer-led workplace group walking intervention designed to engage physically inactive employees. A 16-week pilot cluster randomized controlled trial consisted of enhanced (5 worksites; n = 50 participants) and minimal treatment (3 worksites; n = 47) conditions. All participants were provided with a Fitbit Zip and information on health benefits of walking. Enhanced treatment participants had access to a mobile phone app incorporating behavior change techniques, were trained on principles of autonomous motivation, and had a peer leader trained in a motivationally supportive communication style. Feasibility assessments included recruitment and drop-out rates, assessment completion rates, training acceptability (walkers and peer leaders), and intervention acceptability (walkers only). Outcomes assessed included movement-related behaviors (assessed via activPAL devices), cardio-metabolic risk factors, motivation to walk, and well-being, and these measures were taken at baseline and post-intervention. The results supported intervention feasibility. Preliminary efficacy evidence was mixed. Markers of cardio-metabolic risk improved in the enhanced treatment only. Autonomous motivation increased in both conditions. There were no changes in step counts, standing, and sitting time, or well-being. Further fine tuning is needed before a definitive RCT.

Dyadic interventions to promote physical activity and reduce sedentary behaviour: systematic review and meta-analysis.

Several interventions have targeted dyads to promote physical activity (PA) or reduce sedentary behaviour (SB), but the evidence has not been synthesised. Sixty-nine studies were identified from MEDLINE, PsycINFO, and Web of Science, and 59 were included in the main meta-analyses (providing 72 independent tests). Intervention details, type of dyadic goal, participant characteristics, and methodological quality were extracted and their impact on the overall effect size was examined. Sensitivity analyses tested effect robustness to (a) the effects of other statistically significant moderators; (b) outliers; (c) data included for participants who were not the main target of the intervention. Dyadic interventions had a small positive, highly heterogeneous, effect on PA g = .203, 95% CI [0.123-0.282], compared to comparison conditions including equivalent interventions targeting individuals. Shared target-oriented goals (where both dyad members hold the same PA goal for the main target of the intervention) and peer/friend dyads were associated with larger effect sizes across most analyses. Dyadic interventions produced a small homogeneous reduction in SB. Given dyadic interventions promote PA over-and-above equivalent interventions targeting individuals, these interventions should be more widespread. However, moderating factors such as the types of PA goal and dyad need to be considered to maximise effects.

Longitudinal associations between exercise identity and exercise motivation: A multilevel growth curve model approach.

Past work linking exercise identity and exercise motivation has been cross-sectional. This is the first study to model the relations between different types of exercise identity and exercise motivation longitudinally. Understanding the dynamic associations between these sets of variables has implications for theory development and applied research. This was a longitudinal survey study. Participants were 180 exercisers (79 men, 101 women) from Greece, who were recruited from fitness centers and were asked to complete questionnaires assessing exercise identity (exercise beliefs and role-identity) and exercise motivation (intrinsic, identified, introjected, external motivation, and amotivation) three times within a 6 month period. Multilevel growth curve modeling examined the role of motivational regulations as within- and between-level predictors of exercise identity, and a model in which exercise identity predicted exercise motivation at the within- and between-person levels. Results showed that within-person changes in intrinsic motivation, introjected, and identified regulations were positively and reciprocally related to within-person changes in exercise beliefs; intrinsic motivation was also a positive predictor of within-person changes in role-identity but not vice versa. Between-person differences in the means of predictor variables were predictive of initial levels and average rates of change in the outcome variables. The findings show support to the proposition that a strong exercise identity (particularly exercise beliefs) can foster motivation for behaviors that reinforce this identity. We also demonstrate that such relations can be reciprocal overtime and can depend on the type of motivation in question as well as between-person differences in absolute levels of these variables.

Preventing occupational injury among police officers: does motivation matter?

BACKGROUND: Injury prevention is an important issue for police officers, but the effectiveness of prevention initiatives is dependent on officers' motivation toward, and adherence to, recommended health and safety guidelines. AIMS: To understand effects of police officers' motivation to prevent occupational injury on beliefs about safety and adherence to injury prevention behaviours. METHODS: Full-time police officers completed a survey comprising validated psychometric scales to assess autonomous, controlled and amotivated forms of motivation (Treatment Self-Regulation Questionnaire), behavioural adherence (Self-reported Treatment Adherence Scale) and beliefs (Safety Attitude Questionnaire) with respect to injury prevention behaviours. RESULTS: There were 207 participants; response rate was 87%. Hierarchical multiple regression analyses demonstrated that autonomous motivation was positively related to behavioural adherence, commitment to safety and prioritizing injury prevention. Controlled motivation was a positive predictor of safety communication barriers. Amotivation was positively associated with fatalism regarding injury prevention, safety violation and worry. CONCLUSIONS: These findings are consistent with the tenets of self-determination theory in that autonomous motivation was a positive predictor of adaptive safety beliefs and adherence to injury prevention behaviours.

The effects of training group exercise class instructors to adopt a motivationally adaptive communication style.

Drawing from self-determination theory (Deci & Ryan, 2002), we developed and tested an intervention to train fitness instructors to adopt a motivationally adaptive communication style when interacting with exercisers. This was a parallel group, two-arm quasi-experimental design. Participants in the intervention arm were 29 indoor cycling instructors (n = 10 for the control arm) and 246 class members (n = 75 for the control arm). The intervention consisted of face-to-face workshops, education/information video clips, group discussions and activities, brainstorming, individual planning, and practical tasks in the cycling studio. Instructors and exercisers responded to validated questionnaires about instructors' use of motivational strategies and other motivation-related variables before the first workshop and at the end of the third and final workshop (4 months later). Time × arm interactions revealed no significant effects, possibly due to the large attrition of instructors and exercisers in the control arm. Within-group analyses in the intervention arm showed that exercisers' perceptions of instructor motivationally adaptive strategies, psychological need satisfaction, and intentions to remain in the class increased over time. Similarly, instructors in the intervention arm reported being less controlling and experiencing more need satisfaction over time. These results offer initial promising evidence for the positive impact of the training.

Narcissism and coach interpersonal style: A self-determination theory perspective.

Athletes' sport experiences are often influenced by the interpersonal styles of communication used by their coaches. Research on personality antecedents of such styles is scarce. We examined the link between a well-researched personality trait, namely narcissism, and two types of coaching interpersonal style, namely autonomy-supportive and controlling styles. We also tested the mediating roles of dominance and empathic concern in explaining the relations between narcissism and the two coaching interpersonal styles. United Kingdom-based coaches (N = 211) from various sports completed a multi-section questionnaire assessing the study variables. Regression analyses revealed a positive direct relation between narcissism and controlling coach behaviors. Furthermore, empathy (but not dominance) mediated the positive and negative indirect effects of narcissism on controlling and autonomy-supported interpersonal styles, respectively. We discuss these findings in terms of their implications for coaching and the quality of athletes' sport experiences.

Motivational climate, goal orientation, perceived sport ability, and enjoyment within Finnish junior ice hockey players.

The aim of this study was to investigate the relations among situational motivational climate, dispositional approach and avoidance achievement goals, perceived sport ability, and enjoyment in Finnish male junior ice hockey players. The sample comprised 265 junior B-level male players with a mean age of 17.03 years (SD = 0.63). Players filled questionnaires tapping their perceptions of coach motivational climate, achievement goals, perceived sport ability, and enjoyment. For the statistical analysis, players were divided into high and low perceived sport ability groups. Multigroup structural equation modeling (SEM) revealed an indirect path from task-involving motivational climate via task-approach goal to enjoyment. Additionally, SEM demonstrated four other direct associations, which existed in both perceived ability groups: from ego-involving motivational climate to ego-approach and ego-avoidance goals; from ego-approach goal to ego-avoidance goal; and from task-avoidance goal to ego-avoidance goal. Additionally, in the high perceived sport ability group, there was an association from task-involving motivational climate to enjoyment. The results of this study reveal that motivational climate emphasizing effort, personal development and improvement, and achievement goal mastering tasks are significant elements of enjoyment in junior ice hockey.

The relation between student motivation and student grades in physical education: A 3-year investigation.

Enhancing students' academic engagement is the key element of the educational process; hence, research in this area has focused on understanding the mechanisms that can lead to increased academic engagement. The present study investigated the relation between motivation and grades in physical education (PE) employing a 3-year longitudinal design. Three hundred fifty-four Greek high school students participated in the study. Students completed measures of motivation to participate in PE on six occasions; namely, at the start and the end of the school year in the first, second, and third year of junior high school. Students' PE grades were also recorded at these time points. The results of the multilevel growth models indicated that students' PE grades increased over the 3 years and students had better PE grades at the end of each year than at the beginning of the subsequent year. In general, students and classes with higher levels of controlling motivation achieved lower PE grades, whereas higher levels of autonomous motivation were associated with higher PE grades. These findings provide new insight on the associations between class- and individual-level motivation with objectively assessed achievement in PE.

A self-determination approach to the understanding of motivation in physical education.

BACKGROUND: It is widely acknowledged that Physical Education (PE) can play a potentially important role in enhancing public health by creating positive attitudes toward exercise and by promoting health-related fitness programmes. However, these initiatives will have limited success if students are not motivated to participate actively in their PE lessons. AIM: A sequence of motivational processes, proposed by Vallerand (1997), was tested in this study. The sequence has the form 'social factors-->psychological mediators-->types of motivation-->consequences'. SAMPLE: Participants were 424 British students aged 14-16 years from Northwest England. METHOD: Questionnaires were used to measure cooperative learning, self-referenced improvement, and choice of tasks (social factors), perceived competence, autonomy, and relatedness (psychological mediators), intrinsic motivation, identification, introjection, external regulation, and amotivation (types of motivation), and boredom, effort, and future intention to exercise (consequences). RESULTS: A SEM analysis showed that perceived competence was the major psychological mediator. Intrinsic motivation was related to positive consequences, whereas external regulation and amotivation were predictors of negative consequences. A multisample analysis indicated that the model was largely invariant across gender. CONCLUSIONS: The findings underline the importance of perceived competence and intrinsic motivation in compulsory PE.

Empirical links between achievement goal theory and self-determination theory in sport.

The aim of this study was to examine the empirical links between achievement goal theory and self-determination theory in sport. Addressing theoretical and methodological limitations of previous research, the study tested the independent and interactive effects of goal orientations and perceived competence on seven motivational variables with different degrees of self-determination. Regression analyses of data collected from 247 British university students showed that task orientation predicted motivational variables with high self-determination. In contrast, ego orientation predicted motivational variables with low self-determination. Perceived competence predicted both high self-determined and low self-determined motivational variables. A significant interaction emerged between task and ego orientations in predicting external regulation. The results suggest the adaptive role of task orientation in facilitating self-determined motivation in sport. However, the findings are not conclusive, as the variance explained in most analyses was relatively small. Suggestions are offered for a more comprehensive empirical testing of the links between the two theories.

Affect and achievement goals in physical activity: a meta-analysis.

Achievement goal orientation theory has been the subject of extensive research in recent years. In view of the importance of identifying the motivational antecedents of affect in physical activity, this study examined through meta-analysis the conflicting evidence regarding the links between different achievement goals and emotions. Using the formulas of Hunter and Schmidt (1), correlations were gathered from 41 independent samples and were corrected for both sampling and measurement errors. The results showed that task orientation and positive affect were moderately-to-highly correlated and in a positive fashion, whereas the relationship between task orientation and negative affect was negative and moderate to small. Both correlations were found to be heterogeneous, and so moderators were sought. The relationships between ego orientation and positive and negative affect were positive but very small, with the former being heterogeneous. Moderators coded were the time frame of affect (independent of context vs. after an athletic event), the physical activity setting (school physical education vs. recreation vs. competitive sport), age (university vs. school students), nationality (British vs. American), nature of negative affect (high vs. low arousal), and the publication status of the studies (published vs. unpublished). Lastly, a subset of the corrected correlations were inserted into a structural equation modelling analysis in order to look concurrently at the relationships among all the variables.

A review of motivational climate in physical activity.

Here we provide, within a social-cognitive framework, a critical review of research on the motivational impact of different psychological climates in physical activity. Motivational, cognitive, affective and behavioural outcomes are considered in sport, school physical education and exercise. We first review laboratory and field studies that tried to manipulate the perceived structures of motivational environments and to examine the subsequent outcomes on participants' cognitive and affective responses. Then we discuss studies influenced by the work of Ames in classroom settings and involving questionnaires to measure individuals' perceptions of 'motivational climates'. The impact of mastery and performance climates on various indices of motivation is narratively reviewed, and statistically estimated effect sizes from 14 studies (n = 4484) are presented as supporting evidence. We conclude that a mastery motivational climate is associated with more adaptive motivational patterns, while a performance climate is linked with less adaptive or maladaptive motivational and affective responses. Future research should determine the personal and situational variables that can moderate the impact of such relationships. Furthermore, a broader perspective is proposed, to understand the creation of perceived motivational climates, which is based on the integration of political, cultural, coaching and parental influences.

The relationship between achievement goal profile groups and perceptions of motivational climates in sport.

The purpose of the present study was to expand on previous research that has found compatibility between individuals' views on achievement and the type of achievement that was promoted in the sport environment they belonged to. However, this line of research has ignored the fact that the two main goal orientations are largely independent and that their impact in combination is often different from their effects examined separately. The present study, therefore, examined which combinations of goal orientations are compatible with perceptions of mastery and performance climates in a sample of 146 British university students. With regard to mastery climate, the analysis showed that the critical factor was the degree of task orientation since those with high scores in this factor (irrespective of the degree of their ego orientation) perceived the climate as more mastery-oriented than those with low scores in task orientation. This was substantiated by the large differences in effect sizes between the high- and low-task groups. As far as performance climate was concerned, the most negative perceptions of climate were held by those who were rated both low in task orientation and high in ego orientation. A general inference from these results is that high task orientation is motivationally adaptive, whereas high ego orientation is not motivationally detrimental as long as it is accompanied by a high task orientation. These findings are in contrast with previous suggestions that have called for the enhancement of task orientation with the concurrent suppression of ego orientation. Our results are, however, consonant with studies which have employed a goal profiles analysis in sport and in physical education, and with empirical evidence from real sport settings.

The relationship between competitive anxiety, achievement goals, and motivational climates.

The purpose of this study was to examine the relationships of achievement goal orientations and perceived motivational climate to perceptions of the intensity and direction of competitive state anxiety in a sample of university athletes representing various team sports. Although some studies have demonstrated that task orientation and mastery climate are associated with adaptive emotional patterns and ego orientation and performance climate are linked to less adaptive emotions, others have not verified these findings. In the present study, structural equation modeling was used to test these links. The results showed that perceptions of a performance climate were associated with ego orientation, whereas perceptions of a mastery climate were linked to task orientation. Furthermore, no significant links were found between task orientation and direction of competitive anxiety, while it was shown that the impact of ego orientation on the intensity and direction of cognitive and somatic anxiety was exerted through self-confidence. No significant direct links were found between motivational climates and competitive anxiety, thus implying that motivational climates may have an indirect impact on affective responses through the different goal orientations. The findings of the present study are discussed along with suggestions for examining situational and individual difference variables that may explain the relationships between intensity and direction of competitive anxiety and achievement goals and motivational climates.
