Increases In Autonomous Motivation Research Articles

Self-efficacy and autonomous motivation are associated with lower sugar-sweetened beverage consumption in low-income overweight and obese mothers of young children.

Sugar-sweetened beverage (SSB) consumption is strongly associated with obesity. Autonomous motivation and self-efficacy, key concepts of self-determination theory, may influence SSB consumption. Low-income mothers of young children experience disproportionate rates of obesity. Whether autonomous motivation and self-efficacy are associated with SSB consumption in low-income mothers of young children is unknown. This exploratory secondary data analysis explored whether autonomous motivation or self-efficacy were associated with SBB consumption using data from a lifestyle intervention for low-income, overweight or obese mothers with young children. Participants (N = 311) completed surveys assessing autonomous motivation, self-efficacy, and SSB consumption at baseline, after the 16-week intervention, and at 3-month follow-up. Using baseline data, we performed linear regression models to explore associations of self-efficacy and autonomous motivation with SSB consumption. We also performed mixed effects models to explore whether autonomous motivation or self-efficacy were associated with SSB consumption over time. At baseline, a one-point increase in autonomous motivation and self-efficacy were associated with 4.36 (p < 0.001) and 6.43 (p = 0.025) fewer ounces of SSB consumption per day, respectively. In longitudinal models, SSB consumption decreased over time. Change in SSB consumption was associated with self-efficacy (B = -4.88; p = 0.015) and autonomous motivation (B = -2.29; p = 0.008). Our findings suggest self-efficacy and autonomous motivation may influence SSB consumption among mothers of young children with overweight and obesity. Further investigation should explore if self-efficacy and autonomous motivation have long-term effects on SSB consumption.

Effects of a Pilot Music Therapy Intervention on Motivation in Patients with Severe Hypercholesterolemia

Patients with an LDL-C ≥ 190mg/dL benefit from a healthy lifestyle and use of medications to lower their risk for cardiovascular disease (CVD) events. Change in autonomous motivation and perceived competence are viable targets for reducing CVD risk according to Self-Determination Theory. A pilot randomized controlled trial of music therapy for 31 very high LDL-C subjects found no between 1 or 2 session group different effects on motivation, LDL-C or non-HDL-C. Perceived competence for healthy lifestyle significantly increased (p&lt;0.05), mean LDL-C decreased from 131 to 87 mg/dL (p&lt;0.0005), and mean non-HDL-C decreased from 155 to 113 mg/dL (p=0.001) after music therapy in all participants. An increase in autonomous motivation for medication use predicted a in the change in LDL-C (p&lt;0.05). Music therapy may enhance motivation for reducing CVD risk. Autonomous motivation for medication use and perceived competence for lifestyle change may be useful targets of future interventions for high cholesterol.

How do vaccination intentions change over time? The role of motivational growth.

Across nationwide rollout of COVID-19 vaccination, people in Belgium differed widely in their vaccination intention. In the present study, we examined (a) how people's vaccination intentions changed during the vaccination rollout and (b) whether changes in motivation (i.e., autonomous, controlled, and distrust-based (a)motivation) predicted changes in vaccination intention, thereby taking into account people's vaccination intention at baseline. Using 4 subsamples of participants who were vaccinated at different time points (ntotal = 10,799) between December 2020 and June 2021; we used latent change modeling and latent growth curve modeling to examine the associations among initial levels and changes in vaccination motivation and vaccination intention. Across subsamples, changes in vaccination intention were found to be qualified by changes in motivation. An increase in autonomous motivation was related to a positive shift in vaccination intention, while an increase in both controlled motivation and distrust-based amotivation was related to a negative shift in vaccination intention. Moreover, autonomous motivation predicted especially an increase in vaccination intention among those initially low in vaccination intention, whereas an increase in either controlled motivation or distrust-based amotivation especially predicted a decrease in vaccination intention among those initially high in vaccination intention. Findings suggest that a growing sense of ownership and a reduction in distrust is critical for individuals to develop a stronger intention to get vaccinated, particularly when people had initially low vaccination intentions. We discuss conceptual, methodological, and practical implications. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Supporting Autonomous Motivation for Physical Activity With Chatbots During the COVID-19 Pandemic: Factorial Experiment.

Although physical activity can mitigate disease trajectories and improve and sustain mental health, many people have become less physically active during the COVID-19 pandemic. Personal information technology, such as activity trackers and chatbots, can technically converse with people and possibly enhance their autonomous motivation to engage in physical activity. The literature on behavior change techniques (BCTs) and self-determination theory (SDT) contains promising insights that can be leveraged in the design of these technologies; however, it remains unclear how this can be achieved. This study aimed to evaluate the feasibility of a chatbot system that improves the user's autonomous motivation for walking based on BCTs and SDT. First, we aimed to develop and evaluate various versions of a chatbot system based on promising BCTs. Second, we aimed to evaluate whether the use of the system improves the autonomous motivation for walking and the associated factors of need satisfaction. Third, we explored the support for the theoretical mechanism and effectiveness of various BCT implementations. We developed a chatbot system using the mobile apps Telegram (Telegram Messenger Inc) and Google Fit (Google LLC). We implemented 12 versions of this system, which differed in 3 BCTs: goal setting, experimenting, and action planning. We then conducted a feasibility study with 102 participants who used this system over the course of 3 weeks, by conversing with a chatbot and completing questionnaires, capturing their perceived app support, need satisfaction, physical activity levels, and motivation. The use of the chatbot systems was satisfactory, and on average, its users reported increases in autonomous motivation for walking. The dropout rate was low. Although approximately half of the participants indicated that they would have preferred to interact with a human instead of the chatbot, 46.1% (47/102) of the participants stated that the chatbot helped them become more active, and 42.2% (43/102) of the participants decided to continue using the chatbot for an additional week. Furthermore, the majority thought that a more advanced chatbot could be very helpful. The motivation was associated with the satisfaction of the needs of competence and autonomy, and need satisfaction, in turn, was associated with the perceived system support, providing support for SDT underpinnings. However, no substantial differences were found across different BCT implementations. The results provide evidence that chatbot systems are a feasible means to increase autonomous motivation for physical activity. We found support for SDT as a basis for the design, laying a foundation for larger studies to confirm the effectiveness of the selected BCTs within chatbot systems, explore a wider range of BCTs, and help the development of guidelines for the design of interactive technology that helps users achieve long-term health benefits.

Autonomous Motives Foster Sustained Commitment to Action: Integrating Self-Determination Theory and the Social Identity Approach.

Social change movements may take years or decades to achieve their goals and thus require ongoing efforts from their supporters. We apply the insights of self-determination theory to examine sustained collective action over time. We expected that autonomous motivation, but not controlled motivation, would predict sustained action. We also examine whether autonomous motivation shapes and is shaped by social identification as a supporter of the cause. Longitudinal data were collected from supporters of global poverty reduction (N = 263) at two timepoints 1 year apart. Using latent change score modeling, we found that increases in autonomous motivation positively predicted increases in opinion-based group identification, which in turn predicted increases in self-reported collective action. Controlled motivation (Time 1) negatively predicted changes in action. We concluded that autonomous motivation predicts sustained action over time, while promoting controlled motives for action may backfire because it may undermine identification with the cause.

Predicting Research Productivity in STEM Faculty: The Role of Self-determined Motivation.

How are university faculty members in STEM disciplines motivated to conduct research, and how does motivation predict their success? The current study assessed how multiple types of self-determined motivation predict research productivity in a sample of 651 faculty from 10 US institutions. Using structural equation modeling, the basic psychological needs of autonomy and competence predicted autonomous motivation (enjoyment, value) that, in turn, was the strongest predictor of self-reported research productivity. Using negative binomial regression, autonomous motivation was the strongest predictor of faculty publications and citations, with a one-standard deviation increase in autonomous motivation (approximately a half response option on a 1–5 Likert scale) corresponding to an 11.63% increase in publications and a 22.57% increase in citations over a three-year period. Occupational and social-environmental background variables (e.g., research percentage on contract, career age, balance, collegiality), as well as controlled motivation (guilt, rewards), had comparatively limited predictive effects. These results are of relevance to higher education institutions aiming to support scholarly productivity in STEM faculty in identifying specific beneficial and detrimental aspects of faculty motivation that contribute to measurable gains in research activity.

Exploring Students' Use of a Mobile Application to Support Their Self-Regulated Learning Processes.

Being able to self-regulate one’s learning is essential for academic success but is also very difficult for students. Especially first year students can be overwhelmed with the high study load and autonomy in higher education. To face this challenge, students’ monitoring and self-regulated learning (SRL) processes are crucial. Yet, often students are not aware of effective SRL strategies or how to use them. In this study, the use of a mobile application with gamification elements (i.e., Ace Your Self-Study App) to support first-year university students’ SRL processes was investigated. In Study 1a, the Ace your self-study app was implemented in a first-year psychology course, and students’ SRL skills, motivation, self-efficacy, app use and satisfaction, and performance were measured. The results showed a significant increase in autonomous motivation, controlled motivation, and metacognitive self-regulation skills (MSR-R) across the 5-week course. Moreover, students who used the mobile application with gamified elements showed higher autonomous motivation. Nevertheless, most students used the app only for a limited number of self-study sessions. In Study 1b, students’ self-study experiences were captured using focus group interviews to shed some more light on why students did or did not use the app. The results show that if students feel they do not need support for their SRL processes during self-study, they are less inclined to use the app. Specifically, regarding using study strategies, it was found that only if students’ strategies do not work well in their perception, they feel the need to change their way of studying and choose another strategy. These results are discussed in the context of theory on SRL and how to support it.

Cross-sectional, longitudinal relationships of gender, academic motivation, learning activities, and lifestyle activities with academic performance among Japanese children: A 3-year sequential cohort study

Little is known about the longitudinal relationships of gender, academic motivation, learning activities, and lifestyle activities with academic performance in non-Western contexts. Thus, the present study aimed to investigate the longitudinal relationships of gender, academic motivation, learning activities, and lifestyle activities with academic performance through a 3-year sequential cohort study with 271 Japanese children aged 8–14. Results of multivariate latent curve modeling revealed that an increase in the frequency of having breakfast contributes to improvement in academic performance in Japanese; an increase in autonomous motivation and sleep duration contributes to improvement in Japanese performance among younger Japanese children; and an increase in the frequency of exercise contributes to promotion of Japanese performance among older Japanese children. Furthermore, an increase in the duration of private tutoring contributes to improvement in math performance among Japanese children and rise in introjected regulation and increase in daily study duration contributes to improvement in math performance among older Japanese children. These findings imply that, to effectively promote academic performance in Japanese, it would be useful for parents and educators to ensure that children have breakfast daily, promote autonomous motivation among children starting at a young age, and ensure that children have regular exercise as they grow older. Moreover, to effectively promote math performance, parents and educators must ensure that children receive private tutoring from a young age, promote introjected regulation and increase the time spent studying among children as they grow older.

Does increasing autonomous motivation or perceived competence lead to health behavior change? A meta-analysis.

Despite abundant observational and experimental tests, it is not yet clear whether enhancing autonomous motivation or perceived competence leads to health behavior change. We identified interventions that aimed to change these constructs and quantified the magnitude of changes in behavior observed when interventions generated increases in autonomous motivation, perceived competence, or both. Computerized searches and additional strategies identified 67 articles that yielded 135 effect sizes relevant to our research questions. Random effects meta-analyses were conducted via STATA. Interventions increased autonomous motivation and perceived competence in 31% and 38% of tests, respectively. Increasing autonomous motivation led to a medium change in health behaviors (d+ = .47, 95% CI [.44, .83]) and increasing perceived competence generated a small-to-medium change (d+ = .34, 95% CI [.22, .47]). Interventions that failed to generate significant improvements in autonomous motivation and perceived competence had much smaller effects on behavior change (d+ = .13 and .10, respectively). There was little evidence of synergistic effects. Changing both autonomous motivation and perceived competence (d+ = .42) did not lead to a larger effect on behavior compared with changing autonomous motivation on its own (d+ = .61), but had a larger effect compared with changing perceived competence on its own (d+ = .21). The present review suggests that autonomous motivation and perceived competence are valid targets for interventions to promote health behavior change but also indicates that research is warranted to ensure that interventions more effectively engage these targets.

Can We Communicate Autonomy Support and a Mandate? How Motivating Messages Relate to Motivation for Staying at Home across Time during the COVID-19 Pandemic

ABSTRACT A multi-wave study across two months tested changes in motivation for staying at home at the beginning of the COVID-19 outbreak in the UK and US in 683 living-alone older adults (mean age = 53 years), those that might experience greater psychological costs of being isolated for long periods of time. The study was focused on changes in two types of motivation: autonomous motivation- finding importance in the task of staying at home, and controlled motivation- staying at home because of felt pressure or choicelessness, as autonomous motivation predicts effective behavior change better than controlled motivation, especially long-term. Predictions grounded in self-determination theory (SDT) tested whether three motivating aspects of messages to stay at home from governmental and public health agencies, physicians, the news, and family and friends predicted changes in these motivations across time. Perceiving messages to stay at home as controlling predicted increases in controlled motivation and decreases in autonomous motivation over two months. Conversely, perceiving messages to stay at home as autonomy supportive predicted increases in autonomous motivation over two months. Results for mandated orders to stay at home were intriguing: they related to increases in both controlled and autonomous motivations over time. Exploratory analyses revealed that increases in autonomous motivation over time predicted actual time spent at home reported at Wave 2, whereas increases in controlled motivation did not relate. Discussion focuses on contributions to theory and public health messaging about behavioral change.

Effects of using the WhatsApp application on language learners motivation: a controlled investigation using structural equation modelling

The study of language learners’ motivation has long been considered a key, determining factor of success in second/foreign language acquisition. Based on self-determination theory (SDT), the more autonomously motivated learners are, the better they engage in an activity. To sustain autonomous motivation, the learners’ basic psychological needs (BPN) of autonomy, competence, and relatedness should be satisfied. Nevertheless, the role of these three components and their relation to autonomous motivation in the mobile-assisted language learning (MALL) context has not yet been addressed in the literature. Therefore, a social networking mobile application (WhatsApp) has been used to explore how teachers’ informal use of such an application relates to an increase in students’ motivation. A quasi-experimental design was adopted for two groups of Saudi university students enrolled in the English language department at two major universities (N = 447). The structural model revealed a significant improvement in the effects of Time 1 autonomy on Time 2 autonomous motivation as well as in the effects of Time 1 autonomous motivation on Time 2 autonomous motivation exclusively in the experimental group. The two-time repeated measure of ANOVA substantiated the increase in autonomous motivation exclusively among students in the experimental group. This study contributed to greater recognition of the advantages and challenges of applying WhatsApp as a tool of MALL in the educational system.

Autonomous motivation and support flourishes for individuals higher in collaborative personality factors: Agreeableness, assisted autonomy striving, and secure attachment.

Individuals who strive autonomously for their goals, and who perceive autonomy supportive environments are more successful during goal pursuit. What dispositional factors predict autonomy flourishing during goal pursuit? Four longitudinal studies were conducted over an 8-month academic year, and university students (Ntotal =1,544) completed surveys on motivation, support, and personality. Structural equation models were created using Mplus software to test whether collaborative personality factors were related to growth in autonomous motivation and autonomy support. All three distinct collaborative personality factors, trait Agreeableness, assisted autonomy striving, and secure parental attachment, were related to increases in autonomous motivation over the academic year. Conscientiousness, assisted autonomy, and secure attachment were related to increases in perceived autonomy support. A higher order latent collaborative traits factor, composed of Agreeableness, assisted autonomy, and secure attachment was found to be related to increased autonomous motivation and support over the academic year and resulted in increased goal progress. These results suggest that individuals higher in collaborative personality factors experience growth in personal autonomy during goal pursuit. Future research is needed to determine how to promote collaboration in goal pursuit to further help individuals successfully strive for their goals.

Sport Motivation as a Possible Indicator of Concussion Reporting Intentions Among Young Athletes.

To assess the relationship between sport motivation and intentions to report concussion symptoms among young adult athletes. Cross-sectional study (level of evidence: 3). One thousand three hundred five young adult athletes of various sports and levels of competitiveness from the Survey Sampling International panel. Data were collected through an online survey. Ordinary least squares regression was used to examine the relationship between motivation and reporting intentions controlling for competitiveness and perceived risk of injury. Athletes who play their sport for self-regulated (autonomous) reasons have higher intentions to seek care for concussion-like symptoms, whereas those who play to achieve gains external to the sport or avoid punishment (controlled motivation) have lower intentions. A one-point increase in autonomous motivation was associated with an 11.5-point increase in reporting intention (t = 6.629, P < 0.001), whereas a one-point increase in controlled motivation was associated with an 8.1-point decrease in reporting intention (t = -4.562, P < 0.001). Betas from the model suggested that autonomous motivation had a stronger effect than controlled motivation (0.226 vs -0.163). Innovation in care, concussion education, and cultivation of team culture supportive of autonomous motivation could increase concussion reporting. Measuring sport motivation may reveal which athletes require more proactive attention to ensure symptoms are not concealed. Furthermore, messages to reinforce autonomous motivation may increase willingness to report.

Killing two birds with one stone: The role of motivational resources in predicting changes in achievement and school well-being beyond intelligence

This study investigated whether motivational resources play a role in predicting changes in students’ achievement and well-being above and beyond the role of intelligence during the transition to secondary school. The motivational resources entailed autonomous and controlled motivation as conceived in Self-Determination Theory and implicit beliefs of intelligence as defined in Dweck's perspective. We used two waves of data from a larger longitudinal study, thereby following 6th grade students in the transition to secondary education (N = 2546, Mage = 11.52 years, 49.8% boys). Results of Latent Change Modeling revealed that, after controlling for the role of intelligence in the prediction of standardized math achievement tests, motivational resources played a supplementary role, both at the level of interindividual differences and at the level of intra-individual change. Students with higher initial levels of autonomous motivation obtained higher initial test scores, reported higher school well-being, and made greater progress in both outcomes across the transition. An increase in autonomous motivation was also related to an increase in both achievement and well-being. A similar, yet opposite, pattern of findings was obtained for controlled motivation. An entity mindset failed to yield any unique associations. Given that autonomous motivation contributes to both achievement and well-being beyond effects of intelligence, it is critical for educators to nurture this motivational resource as it allows them to kill two birds with one stone.

Conventional Rehabilitation Therapy Versus Telerehabilitation in Cardiac Patients: A Comparison of Motivation, Psychological Distress, and Quality of Life.

Telerehabilitation (TR) has gained attention as a promising rehabilitation format. Our study examined how patients responded to TR and whether it provided adequate support for their lifestyle changes and self-care efforts when compared to conventional rehabilitation (CR). Cardiac patients (n = 136) were randomly assigned to a TR or CR group. The TR group was provided with relevant health care technology for a period of three months, and both groups filled in questionnaires on their motivation for lifestyle changes and self-care psychological distress, and quality of life at 0, 3, 6, and 12 months. Patients in both groups were found to be equally motivated for lifestyle changes and self-care (p < 0.05) and they experienced similar levels of psychological distress and quality of life. TR is comparable to conventional rehabilitation in motivating patients, preventing psychological distress and improving quality of life. Although we observed an initial increase in autonomous motivation in the telerehabilitation group, this positive difference in motivation does not last over time. As such, neither rehabilitation format seems able to ensure long-term motivation. Therefore, TR may serve as a viable replacement for conventional rehabilitation when considered relevant. Further research is needed to enhance long-term motivation, and maybe telerehabilitation can help to achieve this.

Antecedents and consequences of autonomous information seeking motivation

Autonomously motivated individuals tend to enjoy activities more than those who are extrinsically motivated, and they also tend to invest more effort. Grounded in basic psychological needs theory, the current study examines the motivation of students' autonomous information seeking and its relationship with the amount of effort invested in and enjoyment derived from information seeking. Autonomy support and perceived competence were found to explain 34.7% of the variance in autonomous motivation while autonomous motivation, in turn, explained 13.1% of variance in effort and 25.8% variance in enjoyment. The model indicates a positive relationship between basic psychological needs and autonomous motivation. Higher students' autonomy support and perceived competence levels lead to increases in autonomous motivation to seek information. Higher autonomous motivation levels, similarly, lead to higher levels of effort and enjoyment. Findings confirm that intrinsically motivated students enjoy information seeking more and invest more effort in the activity. This highlights the importance of encouraging students to engage in information seeking independently, while providing the necessary guidance that would increase their competence.

Worksite intervention effects on motivation, physical activity, and health: A cluster randomized controlled trial

ObjectivesThe current study tested the hypothesis that a physical activity (PA) intervention in the worksite would lead to increases in autonomous motivation and perceived competence for PA, self-administered regular PA, and cardiorespiratory fitness (CRF), as well as improvements in health (i.e., reduced blood pressure (BP), waist circumference, and improved cholesterol levels). Moreover, the study tested the self-determination theory (SDT) model of health behaviour change. DesignCluster randomized controlled trial. MethodParticipants from a population of employees working within the area of transport and distribution (n = 202) were cluster randomized (n = 6 worksites) to an intervention and a control condition. The 16-week group-based worksite intervention was designed based on the tenets of SDT combined with techniques from motivational interviewing (MI). Participants were assessed at baseline and at post-test five months later. ResultsComplete-case analyses applying multivariate and univariate analysis of variance indicated an overall intervention effect, and moderate to small effect sizes (Cohen's d) in favour of the intervention group on CRF, diastolic BP, and high-density lipoprotein cholesterol (HDL-C), as well as need support for PA, autonomous motivation for PA, and perceived competence for PA. Intention-to-treat analyses demonstrated the same pattern with smaller effect sizes. Path analysis obtained a good fit between the data and the SDT model of health behaviour change. ConclusionsOffering need supportive interventions to enhance autonomous motivation and competence for PA among employees resulted in important improvements in CRF as well as positive changes in health.

How Colleagues Can Support Each Other's Needs and Motivation: An Intervention on Employee Work Motivation

Organisations have flattened and increasingly rely on teamwork. Therefore, colleagues play an increasingly important role in stimulating employee motivation. Adopting Self‐Determination Theory as a guiding framework, the aim of this field experiment was to examine whether team members can be trained in supporting each other's basic psychological needs for autonomy, competence, and relatedness and, hence, increase each other's need satisfaction and autonomous motivation, while decreasing controlled motivation. We delivered training to 146 participants nested in 26 participating teams and assessed basic need satisfaction and autonomous and controlled motivation before and after the intervention. Multilevel regression analyses indicated that employees in the experimental (i.e. intervention) condition had a stronger increase in need satisfaction and autonomous motivation than employees did in the control condition, and that the increase in autonomous motivation was mediated by an increase in need satisfaction. This study provides added value for theory on need satisfaction and demonstrates that a relatively brief intervention among team members may be effective in creating employee need support and increasing autonomous motivation.

Autonomy support and autonomous motivation in the outpatient treatment of adults with an eating disorder.

Across diverse clinical problems, therapists' autonomy support has been found to increase patients' autonomous motivation for change. Being self-motivated has, in turn, been linked to superior treatment response. In people undergoing outpatient eating disorder (ED) treatment, we examined associations among ratings of autonomy support received from therapists and other carers, self-reported engagement in therapy, and clinical outcomes. Ninety-seven women with anorexia nervosa, bulimia nervosa, or a related ED provided measures of motivational status and clinical symptoms at the beginning and end of time-limited (12-16 weeks) segments of specialized treatment. At mid-treatment, patients also rated the extent to which they perceived their individual therapists, group therapists, group-therapy peers, family members, friends, and romantic partners as being autonomy supportive. Overall, multiple regression analyses indicated autonomy support to moderate (rather than mediate) the link between initial autonomous motivation and later change in autonomous motivation-with results indicating that, independently of ED diagnosis or treatment intensity, greater perceived autonomy support (from therapists and nontherapists alike) coincided with larger increases in autonomous motivation over the course of therapy. In turn, higher autonomous motivation at end-of-therapy coincided with larger reductions in eating symptoms. Findings suggest that the experience of autonomy support (from therapists and nontherapists) is associated with increasing motivation in people undergoing ED treatment, and that becoming self-motivated is linked to better outcomes. Such results indicate that support from therapists, relatives, and peers can favorably influence personal engagement in individuals undergoing ED treatment.

Baseline Motivation Type as a Predictor of Dropout in a Healthy Eating Text Messaging Program.

BackgroundGrowing evidence suggests that text messaging programs are effective in facilitating health behavior change. However, high dropout rates limit the potential effectiveness of these programs.ObjectiveThis paper describes patterns of early dropout in the HealthyYou text (HYTxt) program, with a focus on the impact of baseline motivation quality on dropout, as characterized by Self-Determination Theory (SDT).MethodsThis analysis included 193 users of HYTxt, a diet and physical activity text messaging intervention developed by the US National Cancer Institute. Descriptive statistics were computed, and logistic regression models were run to examine the association between baseline motivation type and early program dropout.ResultsOverall, 43.0% (83/193) of users dropped out of the program; of these, 65.1% (54/83; 28.0% of all users) did so within the first 2 weeks. Users with higher autonomous motivation had significantly lower odds of dropping out within the first 2 weeks. A one unit increase in autonomous motivation was associated with lower odds (odds ratio 0.44, 95% CI 0.24–0.81) of early dropout, which persisted after adjusting for level of controlled motivation.ConclusionsApplying SDT-based strategies to enhance autonomous motivation might reduce early dropout rates, which can improve program exposure and effectiveness.
