The Relationship Between Psychological Needs,Self‐Determined Motivation,Exercise Attitudes,and Physical Fitness1

The primary purpose of this study was to examine the relationships between psychological need satisfaction (competence, autonomy, and relatedness), exercise regulations, and motivational consequences proposed by Self‐Determination Theory (SDT; Deci & Ryan, 1985; Ryan & Deci, 2000). The secondary purpose was to explore changes in these constructs over the course of a 12‐week prescribed exercise program. Results indicated competence and autonomy were positively correlated with more self‐determined exercise regulations, which in turn were more positively related to exercise behavior, attitudes, and physical fitness. Multiple regression analyses revealed that exercise behavior mediated the relationship between self‐determined motives and physical fitness, and both identified and intrinsic exercise regulations contributed significantly to the prediction of attitudes. Paired‐sample t tests supported modest to large changes in need satisfaction constructs, as well as identified and intrinsic regulations over the 12‐week exercise program. These results suggest that SDT is a useful framework for studying motivational issues in the exercise domain.     

A Test of Self-Determination Theory in the Exercise Domain

In accordance with self-determination theory (SDT; Deci & Ryan, 1985 ), this study examined the relationship between autonomy support, psychological need satisfaction, motivational regulations, and exercise behavior. Participants ( N =369) were recruited from fitness, community, and retail settings. Fulfillment of the 3 basic psychological needs (i.e., competence, autonomy, and relatedness) related to more self-determined motivational regulations. Identified and introjected regulations emerged as positive predictors of strenuous and total exercise behaviors. Competence need satisfaction also predicted directly—and indirectly via identified regulation—strenuous exercise. For participants engaged in organized fitness classes, perceptions of autonomy support provided by exercise class leaders predicted psychological need satisfaction. Furthermore, competence need satisfaction partially mediated the relationship between autonomy support and intrinsic motivation. These findings support SDT in the exercise domain.     

The effects of manipulating goal content and autonomy support climate on outcomes of a PE fitness class

ObjectivesThe present study tested the potential for manipulating adolescents' goals and motives for participation in a school physical education (PE) lesson, and explored the subsequent outcomes on participant experience.DesignA cluster randomized controlled design was used to compare outcomes of four experimentally manipulated PE class conditions alongside a control group.MethodTwenty-four classes comprising 592 students (M age = 13.74 years) were randomized to undertake one of four experimental conditions, or a control condition, during a fitness-based circuits class during a usual PE lesson. The experimental conditions comprised an autonomy-supportive or controlling climate, each with an intrinsic (health and fitness) or extrinsic (looking good to others) goal focus. The control condition comprised a neutral climate with no goal focus. The effect of experimental condition on motivational, affective, and intentional outcomes was analysed using hierarchical linear modelling.ResultsClass-level effects explained less than 10% of variance of study outcomes, suggesting that the impact of lesson manipulations was limited. Where intervention effects were significant, these were contrary to hypotheses guided by self-determination theory (SDT); participants perceived greater lesson value and formed stronger future intentions in the controlling, extrinsic goal focused condition. However, at the individual-level, findings were in line with SDT, in that perceptions of autonomy support and an intrinsic goal focus predicted positive lesson-related outcomes (i.e., motivation, effort, enjoyment, value, exercise-induced affect) and future intention to exercise (Total R² values = .39 to .75).ConclusionsThe findings highlight the practical challenges of manipulating lesson climates in ecological PE settings.     

Testing a self‐determination theory‐based teaching style intervention in the exercise domain

Drawing from self‐determination theory (SDT), this study examined the effect of an autonomy supportive, well structured and interpersonally involving teaching style on exercise class participants' psychological need satisfaction, motivational regulations, exercise behaviour, behavioural intention and affect. Female exercise class participants enrolled in a 10‐week exercise program were exposed to an SDT‐based (i.e. SDTc; n = 25) or typical (i.e. control group; n = 31) teaching style. The control condition reported a significant decrease in autonomy support, amotivation and behavioural intention over time. In addition, they reported a significant increase in competence and introjected regulation. Compared to the control condition, the SDTc reported a significantly greater linear increase in structure and interpersonal involvement, relatedness and competence need satisfaction and positive affect. Attendance rates were significantly higher in the SDTc. SDT‐based social‐contextual characteristics and psychological needs predicted autonomous regulations; all these variables collectively predicted adaptive outcomes.

Goal contents,motivation, psychological need satisfaction,well-being and physical activity: A test of self-determination theory over 6 months

ObjectivesThis investigation examined how Goal Contents Theory, Organismic Integration Theory, and Basic Psychological Needs Theory collectively explain well-being and behavioral outcomes related to physical activity over 6 months. Specifically we examined a model whereby changes in relative intrinsic goal contents → changes in motivation → changes in psychological need satisfaction → well-being and physical activity.Methods and designParticipants were 203 adults from the general population (68.00% female; M_age = 32.57 years, SD = 15.73). Two identical questionnaire packages containing assessments of goal contents, motivational regulations, basic psychological need satisfaction, indicators of well-being and physical activity behavior, separated by six months were given to participants. Residualized change scores were analyzed with path analysis.ResultsResults supported the hypothesized sequence of SDT. Changes in psychological need satisfaction mediated the relationship between changes in autonomous motivation and well-being. A more complex pattern of results emerged for the indirect effects of motivation and psychological need satisfaction between relative intrinsic goals → well-being. Changes in competence satisfaction mediated the relationship between autonomous motivation and physical activity behavior. Moreover, changes in autonomous motivation through competence satisfaction mediated the relationship between relative intrinsic goals and physical activity.ConclusionsFindings support a model based on 3 mini-theories of SDT and suggest that psychological need fulfillment during physical activity could be a key mechanism that facilitates increased well-being and behavior. Findings also highlight the importance of examining competence, autonomy, and relatedness independently (rather than as a composite).     

Students’ motivational responses toward school physical education and their relationship to general self-esteem and health-related quality of life

ObjectivesIn addition to encouraging a physically active lifestyle, the aims of school physical education (PE) also encompass the promotion and development of self-esteem and perceptions of health. Using self-determination theory [SDT; Deci, E.L., & Ryan, R.M. (1991). A motivational approach to self: Integration in personality. In: R.A. Dienstbier (Ed.), Nebraska symposium on motivation: Perspectives on motivation (Vol. 38, pp. 237–288). Lincoln, NE: University of Nebraska] as a conceptual framework, we examined three competing models specifying relations among motivational processes toward PE, students’ general self-esteem, and health-related quality of life (HRQoL).DesignA field correlational prospective design.MethodThree hundred British secondary school students (M age=13.51 years; SD=.76) responded to a multi-section inventory assessing their motivational processes toward school PE. One week later, data pertaining to general self-esteem and HRQoL were obtained.ResultsFollowing minor modifications, structural equation analysis showed the three competing models to provide excellent fit to the study data. All models showed (i) perceptions of autonomy support provided by the PE teacher to positively predict autonomy, competence, and relatedness, (ii) competence and autonomy to positively predict autonomous motivation toward PE, and (iii) direct paths from competence to general self-esteem and from relatedness to HRQoL. Model 1 showed autonomous motivation to positively predict general self-esteem, which in turn positively predicted HRQoL. Model 2 supported a positive path from autonomous motivation to HRQoL, with HRQoL positively predicting general self-esteem. Model 3 supported general self-esteem and HRQoL to be distinct, yet related, dependent variables that were positively predicted by autonomous motivation toward PE.ConclusionThese findings call for future work to examine the causal associations among motivational processes, self-esteem, and HRQoL. The theoretical contributions of SDT to such work are discussed.     

A self-determination process model of physical activity adoption in the context of a randomized controlled trial

Objective: The PA Counseling (PAC) trial tested a primary care intervention using Self-Determination Theory (SDT) as the guiding framework. This paper presents specific results related to SDT constructs in a physical activity (PA) context. Specifically, whether patients who received both brief autonomy supportive PA counseling from their health-care provider and intensive (3 month) autonomy supportive counseling from a PA counselor would report greater levels of autonomy support, autonomous motivation, perceived competence and PA adoption, than patients receiving only brief counseling. In addition, we tested Williams’ SDT process model in the context of PA adoption.Method: Measures of autonomous motivation and perceived competence for PA were measured at baseline and 6 weeks. PA was assessed at baseline and 13 weeks. An autonomy support index was calculated by multiplying minutes of counseling by perceptions of autonomy support. Group differences in autonomy support, autonomous motivation, perceived competence and PA were examined. The SDT process model of PA adoption was tested via path analysis.Results: The results showed higher autonomy support and autonomous motivation at 6 weeks and higher PA levels at 13 weeks for the experimental group. The SDT process model for PA adoption showed that autonomous motivation and perceived competence at 6 weeks significantly predicted 13-week PA for the experimental group.Conclusions: This study provides a rigorous field test of SDT theory in a PA context. It demonstrates the versatility and applicability of the SDT model for health behavior change. SDT-trained PA counselors appear to provide valuable contribution to facilitating patient behavior change, by increasing patient autonomous motivation for PA.

Autonomous forms of motivation underpinning injury prevention and rehabilitation among police officers: An application of the trans-contextual model

The present study applied the trans-contextual model (TCM) to understand the motivational processes underpinning workers?? injury prevention and rehabilitation intentions and behavior. Full-time police officers (N?=?207; M age?=?37.24, SD?=?9.93) completed questionnaire measures of the TCM variables. Covariance-based SEM for the full sample revealed that the effect of autonomy support from supervisor on autonomous motivation for injury prevention (M-injury) was fully mediated by autonomous work motivation (M-work), and the effect of M-injury on intention was fully mediated by attitude and subjective norm. Variance-based SEM for the 87 participants who had recent occupational injury showed that the effect of autonomy support from supervisor on autonomous treatment motivation (M-treatment) was partially mediated by M-work, and the effect of perceived autonomy support from physician on treatment adherence was fully mediated by M-treatment. There was no effect of treatment adherence on recovery length. Findings support the motivational sequence of the TCM in an occupational context.     

Motivational characteristics of obese adolescents toward physical activity: Contribution of self-determination theory

IntroductionRegular physical activity (PA) practice represents a key component of obesity treatment.ObjectiveBased on self-determination theory (SDT), this cross-sectional study aimed to explore the motivational characteristics associated with PA practice among obese adolescents.MethodOne hundred and five overweight or obese adolescents (mean age = 15 years old, SD = 2.69) were questioned about their level of PA, motivational regulations toward PA and level of satisfaction of basic psychological needs.ResultsData revealed that satisfaction of autonomy and relatedness needs is positively associated with autonomous forms of motivation (e.g., for integrated regulation β = .44; and 0.35, respectively, p < .01). Otherwise, non-satisfaction of the needs of autonomy and competence is associated with the most controlled forms of motivation (e.g., for external regulation β = −.27, p < .01; and −.18, p < .05, respectively). In turn, a high level of identified regulation, a low level of external regulation and a high level of satisfaction of the need for competence are associated with weekly PA (β = .28; −.19 and .24, respectively, p < .05).ConclusionSDT appears as an interesting theoretical framework to explore motivational antecedents of PA among obese adolescents.     

Youth athletes’ perception of autonomy support from the coach, peer motivational climate and intrinsic motivation in sport setting: One-year effects

Objectives

Grounded in self-determination theory (SDT; Deci & Ryan, 1985) and achievement goal theory (AGT; Nicholls, 1989), the present study examined the temporal stability and reciprocal relationships among three key variables related to motivation: perceived autonomy support from the coach, task-involving peer motivational climates, and athletes’ intrinsic motivation.

Design

A prospective longitudinal design with data collected on two occasions one year apart over the course of a youth training season.

Method

Young athletes (N = 362, age range 11-16 years) completed measures of the Sport Climate Questionnaire and the Peer Motivational Climate in Youth Sport Questionnaire. One-year later participants completed these questionnaires again along with the Sport Motivation Scale.

Results

Structural equation modeling indicated that perceived autonomy support from the coach and task-involving peer motivational climates exhibited comparatively high stability over a one-year period. In cross-lagged analyses, perceived autonomy support from the coach positively predicted task-involving peer climate one-year later but not vice versa. In addition, both social factors demonstrated a significant direct effect on athletes intrinsic motivation measured concurrently in sport contexts. Further, an alternative structural model supported a longitudinal direct effect of autonomy support from the coach and task-involving peer climate measured on the first occasion on subsequent intrinsic motivation.

Conclusion

Results demonstrated the value of perceived autonomy support from the coach and task-involving peer motivational climate in predicting athletes’ intrinsic motivation over a training year. Findings also suggest that perceived autonomy support from the coach can facilitate later task-involving peer motivational climate.     

The Behavioral Regulation in Exercise Questionnaire (BREQ-4): Psychometric evidence of introjected approach regulation in Portuguese health club exercisers

The assessment of motivation has been a key aspect to the understanding of exercise participation, and research grounded in self-determination theory has presented valid and reliable instruments for that purpose. Given the need to continually refine this latent construct, the present study aimed to translate, adapt, and psychometrically validate a subscale targeting the approach facet of introjection, and to test the pattern of associations between motives for practice, basic psychological needs satisfaction/frustration, and behavioral regulations encompassing the validated introjection subscale, in a sample of health club exercisers.For that purpose, two studies were developed with a total of 1216 health club exercisers. In Study I (n = 806), Confirmatory Factor Analysis and Exploratory Structural Equation Modeling analysis to test the motivational continuum encompassing the introjected approach subscale were performed. In Study II (n = 410) associations and structural models between intrinsic and extrinsic goal contents, basic psychological needs satisfaction and frustration, and behavioral regulations with the new subscale were tested.The correlated seven-factor model with 21 items in Study I displayed good psychometric properties (CFA: χ² = 481.977 (168), p < .001, CFI = 0.936, TLI = 0.915, SRMR = 0.037, RMSEA = 0.048; ESEM: χ² = 178.672 (84), p < .001, CFI = 0.980, TLI = 0.949, SRMR = 0.014, RMSEA = 0.037). The introjected approach regulation added to the preexisting factorial structure did not affect the validity and reliability of the instrument. The results from Study II supported a theoretically expected pattern of associations, in which the introjected regulation of approach is positioned between introjected avoidance and identified regulation along the motivational continuum. Additionally, path estimates depicted criterion validity for the new subscale. All in all, this work presents preliminary evidence for an introjected approach regulation subscale that can be used in health club practices for a better understanding of the motivational quality of exercise practice.     

Integrating meaning in life and self-determination theory to predict physical activity adoption in previously inactive exercise initiates enrolled in a randomized trial

Self-Determination Theory (SDT) suggests that individuals with greater basic psychological needs satisfaction and autonomous motivation are more likely to adopt physical activity (PA). However, few longitudinal studies have examined these processes in exercise initiates outside the context of a formalized intervention. Further, an implicit yet relatively unexplored tenet of SDT is that when behaviors are closely connected to what is meaningful to individuals, those behaviors are more likely to be maintained. This study had two aims: (a) to examine SDT and a sense of meaning in life (MIL) in relation to PA in previously inactive exercise initiates, and (b) to determine whether daily measurement of MIL, mood, and PA impacts PA engagement. Upon joining a fitness center, participants (N = 160; M age = 43.3 years; 77% female) were recruited for a longitudinal study of PA adoption. Participants were randomized to a daily measurement condition (self-monitoring) where they reported daily MIL, mood, and PA or to an attention control condition. All participants self-reported their PA, basic psychological needs satisfaction, behavioral exercise regulation, and MIL at baseline, 4-weeks, and 12-weeks after starting an exercise program. Longitudinal path models were used to examine the relationships among study variables. Cross-sectionally, SDT constructs were largely related to PA in the expected directions. After accounting for SDT processes, baseline MIL was associated with greater PA at 4-weeks (p = .028). There were no differences in PA, SDT constructs, or MIL between the measurement self-monitoring and control groups. MIL predicted PA adoption above and beyond SDT predictors in previously inactive adults. Combined SDT and MIL intervention approaches may enhance PA adoption, and further research should explore their roles in PA adoption and maintenance.     

Motivation and physical activity levels in bariatric patients involved in a self-determination theory-based physical activity program

ObjectiveThis study examines the associations between pre-to post-intervention changes in motivation and physical activity (PA) levels of bariatric patients involved in a 6-month postoperative PA program based on self-determination theory (SDT). We also explore the extent to which patients’ perception of autonomy support and basic psychological need satisfaction during the program were associated with changes in their motivation to exercise.MethodForty patients were assigned to a motivational PA intervention (MPAI-G) or to a control group (CG). Both groups completed questionnaires assessing the variables of interest and wore GT3X accelerometers before surgery and after the program.ResultsThirty-two participants (78.1% female) completed all measures and were included in the present analyses. CG showed greater increases in integrated (d = −1.60, 95% CI [−2.40, −0.81]) and identified regulation (d = −0.75, 95% CI [−1.47, −0.03]) than MPAI-G. However, the MPAI-G experienced increases in introjected regulation (d = 1.95, 95% CI [1.11, 2.79]) and greater decreases in external regulation (d = −1.00, 95% CI [−1.74, −0.27]) than CG, which were associated with decreases in sedentary activity and increases in light and total PA. Oppositely to the CG, amotivation decreased in the MPAI-G (d = −2.98, 95% CI [−3.98, −1.97]) and it was related to increases in light and total PA. Changes in exercise motivation were associated with perceived autonomy support and basic psychological need satisfaction during the program.ConclusionThe SDT-based PA program gave rise to greater changes in controlled forms of motivation and amotivation than in autonomous motivation in post-bariatric surgery patients.     

Global and appearance-contingent self-esteem: Associations with health and attractiveness exercise reasons

Whilst some individuals exercise for health-related reasons, others appear to exercise to bolster physical attractiveness. For the latter, this is often attributed to dissatisfaction with appearance. Few studies, however, have explored if differences in self-esteem may relate to diverse exercise reasons. The present study investigated whether global self-esteem, appearance-contingent self-worth, and appearance satisfaction may be differentially associated with health and attractiveness exercise reasons. It was further sought to explore whether these relations coincided with different motivational regulations. Adults from the east midlands of the United Kingdom (N = 209; 75% female, 25% male; mean age = 29.77 years) completed measures relating to their global and appearance-contingent self-esteem, appearance satisfaction, exercise intentions, and motivations. Structural equation modelling revealed that global self-esteem was positively associated with appearance satisfaction and health reasons for exercise, whereas appearance-contingent self-esteem related to lower appearance satisfaction and attractiveness reasons. Appearance satisfaction had no association with either exercise reason but was associated with intrinsic motivation and lower controlled exercise motivations. Health exercise reasons were positively associated with intrinsic, identified, and introjected motivation, whereas attractiveness reasons were exclusively related to external motivation. The findings highlight the conceptual importance of differentiating the level and contingency of exercisers’ self-esteem. The findings may also have substantive value for exercise practitioners in understanding different reasons for exercise.     

Predicting attitudes and physical activity in an “at-risk” minority youth sample: A test of self-determination theory

ObjectivesThe present work sought to extend past research by (i) testing a model of motivational processes based on the tenets of self-determination theory (SDT; Deci & Ryan [1991. A motivational approach to self: Integration in personality. In R. Dienstbier (Ed.), Nebraska symposium on motivation. Vol. 38. Perceptives on motivation (pp. 237–288). Lincoln, NE: University of Nebraska Press]) in an “at-risk” minority youth sample, (ii) exploring the relationship between motivation and physical activity behavior and attitudes, and (iii) assessing autonomy-support for physical activity from two social agents.DesignA field cross-sectional design, including an assessment of physical activity over 4 days using pedometers.MethodsComplete data were obtained from 237 predominantly low socioeconomic Hispanic 5th–8th grade students (M age=12.11 years; SD=1.21) from an elementary school located in the southwestern region of the United States of America. Four days of physical activity data, height and weight measurements, and responses to a multi-section inventory were collected. A model of hypothesized relationships among the study variables was examined using structural equation modeling.ResultsThe proposed model demonstrated a very good fit to the data [Satorra-Bentler χ² (24)=46.88, p<.01; CFI=.94; IFI=.95; SRMR=.052]. Supporting the study hypotheses, the model showed that students who perceived autonomy-support toward physical activity to be promoted by their teachers and their parents experienced greater levels of need satisfaction variables (viz., autonomy, competence, and relatedness). In turn, the satisfaction of these psychological needs positively predicted autonomous motivation towards physical activity. Autonomous motivation positively predicted greater levels of (i) physical activity and (ii) positive attitudes towards physical activity. Body Mass Index (BMI) was found to be a negative predictor of physical activity.ConclusionsCollectively, the results of the present work provide support for SDT and the application of the framework to enhance our understanding of motivational processes as they relate to physical activity within “at-risk” minority youth.     

The Process by Which Relative Autonomous Motivation Affects Intentional Behavior: Comparing Effects Across Dieting and Exercise Behaviors

A motivational model integrating self-deter-mination theory and the theory of planned behavior was tested in two samples for exercise and dieting behavior respectively. Relative autonomous motivation from self-determination theory was hypothesized to predict intentions to exercise or diet via the mediation of attitudes and perceived behavioral control (PBC) from the theory of planned behavior. It was also expected that attitudes and PBC would predict actual levels of exercise and dieting behavior via the mediation of intentions. Relations in the proposed model were expected to be invariant across the behaviors. Two samples of participants (N = 511) completed measures of the autonomous motives, attitudes, subjective norms, PBC, and intentions with respect to exercise and dieting behavior. Four weeks later, participants self-reported their behavior. Structural equation models supported the replicability of the proposed model in both behaviors. Findings supported the majority of the hypothesized effects in the proposed model across the two health behaviors. However, four effects were significantly different across the two behaviors: the effect of autonomous motives on intentions, subjective norms and PBC on intentions, and intentions on behavior. Findings extend knowledge of the processes by which psychological antecedents from the theories affect health behaviors integral to the maintenance of energy balance.

Changes in students’ goal pursuits and motivational regulations toward healthy behaviors during the pandemic: A Self-Determination Theory perspective

ObjectivesIn this study, we examined how students’ perceptions of teachers and parents’ need-supportive and need-thwarting behaviors, related to their intrinsic and extrinsic goal pursuits, and in turn their motivational regulations toward physical activity in virtual physical education lessons over a semester during the Sars-COV2 pandemic.DesignShort-term longitudinal study.MethodsStudents (M_age = 14.43, SD = 0.99) completed the targeted questionnaires at the beginning (T1, N = 295) and the end (T2, N = 194) of a virtual semester.ResultsThe results of the autoregressive model indicated that all measures were relatively stable from T1 to T2. Neither teachers nor parents’ need-supportive and need-thwarting behaviors at T1 predicted students’ intrinsic goal pursuits at T2, except for teachers’ need-supportive behaviors at T1 negatively marginally predicted students’ extrinsic goal pursuits at T2. The results also showed that intrinsic goal pursuits at T2 positively and negatively related to autonomous motivation and amotivation at T2, respectively. Extrinsic goal at T2 positively related to controlled motivation and amotivation at T2.ConclusionsFindings suggested that teachers need-supportive behaviors are important for decreasing students’ extrinsic goal pursuits, while parents’ need-thwarting behaviors relate to students’ amotivation over time during the lockdown periods. Also, students’ intrinsic goal pursuits would contribute positively to autonomous motivation and negatively to amotivation over time.     

Determinants of physical activity among patients with type 2 diabetes: the role of perceived autonomy support,autonomous motivation and self-care competence

Based on self-determination theory (SDT), this study investigated, whether the three central SDT variables (perceived autonomy support, autonomous motivation and self-care competence), were associated with engagement in physical activity (PA) among patients with type 2 diabetes when the effect of a wide variety of other important life-context factors (perceived health, medication, duration of diabetes, mental health, stress and social support) was controlled for. Patients from five municipalities in Finland with registry-based entitlement to a special reimbursement for medicines used in the treatment of type 2 diabetes (n = 2866, mean age 63 years, 56% men) participated in this mail survey in 2011. Of all measured explanatory factors, autonomous motivation was most strongly associated with engagement in PA. Autonomous motivation mediated the effect of perceived autonomy support on patients’ PA. Thus, perceived autonomy support (from one’s physician) was associated with the patient’s PA through autonomous motivation. This result is in line with SDT. Interventions for improved diabetes care should concentrate on supporting patients’ autonomous motivation for PA. Internalizing the importance of good self-care seems to give sufficient energy to maintain a physically active lifestyle.
