UNASSIGNED: The lack of physical exercise is a global health concern, particularly affecting women. However, there is limited research on factors influencing women\'s sports participation. Recent studies on increasing women\'s physical activity levels differ in methodologies and conclusions. Motivation, as the cornerstone of most human behaviors, has important effects on female motor participation. Self-Determination Theory (SDT) is an important method to study human behavioral motivation and supported by empirical evidence. In the field of women\'s sports, the SDT is also widely used. This review explores the impact of SDT-related factors on women\'s sports participation, considering age variations. It aims to guide future empirical research and promote PA across demographics.
UNASSIGNED: This review, by searching the existing empirical literature in Web of Science, Google Scholar, Elsevier ScienceDirect, CNKI, obtained 32 independent studies, conducted a meta-analysis after coding them, considering 11 influencing factors from the integration of SDT and Basic Psychological Needs Theory.
UNASSIGNED: The study found a significant positive correlation between autonomous motivation and women\'s sports participation, with identified regulation having the strongest influence. Controlled motivation showed no significant impact on women\'s exercise, while amotivation had an inhibitory effect. Enhancing women\'s perception of autonomy, competence, and relatedness significantly promotes sports participation. Age differences were observed in the relationship between autonomous motivation, basic psychological needs, and sports participation, with the strongest effects on women aged 25-40, while the impact was relatively weaker in older women. The correlation between basic psychological needs and female sports participation also has a significant age difference. Thus, different measures should be taken to improve exercise participation in women of different age groups.

Schizophrenia, a debilitating psychiatric disorder, has a long-term impact on social and occupational functioning. While negative symptoms, notably amotivation, are recognized as poor prognostic factors, the positive force of patient motivation (autonomous motivation) remains underexplored. This systematic review, guided by Self-Determination Theory (SDT), investigated the impact of motivation on clinical presentation, and treatment engagement and response in schizophrenia-spectrum disorders. Fifty-five independent studies (N = 6897), using 23 different motivation scales, met inclusion criteria. Results were categorized into cross-sectional and longitudinal correlates of autonomous motivation, and the effects of motivational interventions. Cross-sectionally, autonomous motivation was positively associated with social/occupational functioning, and negatively associated with negative and positive symptom severity. In longitudinal studies, baseline autonomous motivation predicted engagement in and response to social/occupational treatments, with mixed results in cognitive interventions. In the 16 randomized controlled trials (RCTs), the most common motivational interventions were individualized goal setting and goal attainment support, followed by increasing sense of competence by challenging defeatist beliefs, and enhancing relatedness by increasing contact time. Motivational interventions consistently increased autonomous motivation, treatment engagement and response. More studies are needed, particularly studies that monitor motivation during treatment: proximal assessments could facilitate the identification of treatment elements that impact motivation and engagement and inform treatment modifications to enhance the patient experience and improve treatment efficacy.

BACKGROUND: Social media is an integral part of adolescents\' lives and has a strong influence on development and wellbeing. Research examining adolescent social media use and wellbeing is confusing as findings are inconsistent, inconclusive and contradictory. To address this issue, digital wellbeing scholars recommend that researchers adopt a theoretical approach with the aim of increasing meaningfulness and applicability of findings. Hence, this review applies self-determination theory to investigate how adolescent social media use supports and thwarts the basic psychological needs of relatedness, autonomy and competence. Satisfaction of all three psychological needs is essential for optimal development and wellbeing.
METHODS: A scoping review was conducted using a systematic search of five databases relating to adolescent social media use. The preferred items for systematic review and meta-analysis protocols (extension for scoping reviews) was applied resulting in 86 included studies.
RESULTS: Adolescent social media use both supports and thwarts relatedness, autonomy and competence. The findings highlighted how different aspects of adolescent social media use (including intra-personal, inter-personal, situational and environmental factors) contribute to the satisfaction and frustration of basic psychological needs.
CONCLUSIONS: This review illustrates how social media can be both beneficial and detrimental to satisfying the basic psychological needs of relatedness, autonomy and competence. This is important when considering that if psychological needs are satisfied or frustrated in adolescence, the repercussions can have a cascading effect throughout adulthood. This review identifies gaps in the literature and provides suggestions for future research.

Although the physical health of college students is increasingly receiving attention, their autonomous fitness behavior has not been thoroughly investigated. This narrative review conducted a comprehensive literature search through databases such as PubMed, PsycINFO, Web of Science, and the China National Knowledge Infrastructure (CNKI), reviewing studies published up to December 2023. We explored the constructs of autonomy, fitness behavior, and agency, and discussed their integration within the autonomous fitness model. Our findings indicate a lack of comprehensive studies exploring the multifaceted factors influencing autonomous fitness behaviors. Future research should strive to deepen conceptual understanding and further explore the complex dynamics of the transition from autonomy to persistence, employing technological and interdisciplinary methodological perspectives to enhance understanding and promote sustainable fitness habits.

Background: Self-determination theory (SDT) may provide important insights for understanding substance misuse and treatment outcomes. However, to date, the literature applying SDT to substance use and its treatment is varied and difficult to integrate. Methods: The authors searched psycINFO and PubMed on October 26th, 2021 to identify articles applying SDT to substance use and its treatment. Eligible studies were published in peer-reviewed articles in English, on adult populations (18+), and explicitly applied SDT to the context of substance use or its treatment. Results were categorized as studies applying SDT in non-treatment or treatment settings and were synthesized within these categories by substance(s) of focus, primary outcome(s), component(s) of SDT utilized, and relevant findings. Results: The search revealed 38 articles applying SDT in non-treatment (k = 16) and treatment (k = 22) settings. Causality orientations and the basic psychological needs were the most frequently studied components of SDT. Studies that applied SDT in non-treatment settings placed a greater emphasis on causality orientations, whereas treatment studies more frequently targeted or measured basic psychological needs. Conclusions: SDT constructs consistently predicted both substance misuse and treatment outcomes in a theoretically consistent manner, however, several important gaps remain and opportunities for future research are discussed.

UNASSIGNED: Autistic youth participate less in physical education classes and organised sport than their neurotypical peers. We conducted a review of existing studies to investigate what is known about what motivates (and does not motivate) autistic youth to take part in structured physical activities. We systematically searched electronic databases and found 18 publications that met the criteria to be included in this review. Data from these studies were extracted and mapped to the self-determination theory to identify factors that support (or undermine) motivation for autistic youth. We also discussed the findings with autistic individuals and other relevant stakeholders to discover how the review related to their experiences. Our results found competence (youth feeling competent in their athletic and social skills and abilities) to be the most reported psychological need impacting motivation for autistic youth. Intrinsic motivation (participating for enjoyment and satisfaction) was the most common facilitator of motivation. Autism-specific themes outside of the self-determination theory were mapped inductively, and we found that the sensory environment was a prominent theme reported to influence the motivation of autistic youth not covered by the self-determination theory. The findings of this review suggest that supporting the psychological needs of autistic youth can foster motivation to engage in physical activity, although how these needs are met can differ from their neurotypical peers. Future research should examine motivational factors that support engagement in structured physical activities through the lens of autistic youth and their experiences.

Low back pain is a pervasive issue worldwide, having considerable prevalence and a significant impact on disability. As low back pain is a complicated condition with many potential contributors, the use of therapeutic exercise, combined with other techniques such as self-determination theory programmes, has the potential to improve several outcomes. The aim of this systematic review was to explore the effectiveness of combined exercise and self-determination theory programmes on chronic low back pain. This study was designed according to Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. A systematic search in three databases (PubMed/MEDLINE, Web of Science, and Scopus) was conducted from September to November 2023. After screening, a total of five random control trials with patients with chronic low back pain were included in this systematic review and meta-analysis. The results showed significant differences in disability (SMD = -0.98; 95% CI = -1.86, -0.09; p = 0.03) and in quality of life (SMD = 0.23; 95% CI = 0.02, 0.44; p = 0.03) in favour of the intervention group versus the control group.

UNASSIGNED: Boys\' and girls\' food habits diverge in adolescence (13-18 years). This contributes to unequal risks of adverse health outcomes based on sex and gender in adulthood (e.g., heart diseases in men vs. disorder eating in women). Though multi-factorial, why these dietary differences occur is unclear.
UNASSIGNED: To identify the reasons why adolescents\' motivation behind dietary habits differs among genders.
UNASSIGNED: Four databases were searched following PRISMA guidelines. Eligible studies had to use qualitative methodology and report at least one gender unique theme. Reported themes were thematically analyzed, with a sub-analysis by country where the studies were conducted. Quality appraisals were assessed using the Critical Appraisal Skills Programme checklist.
UNASSIGNED: In the 34 eligible articles (n = 1,694 returned) two overarching themes emerged that dictated dietary habits in adolescents: Self-motivators and Uncontrollable factors. Gender differences arose whereby girls highlighted more external motivators (e.g., eat healthier, change dietary habits around boys and be thin to fit traditional norms) over their dietary habits. In contrast, boys focused on more internal motivators (e.g., gain autonomy, eat for enjoyment and pursue gains in physical performance). This suggests that motivation underlying how boys and girls eat differs. These trends were largely consistent across countries.
UNASSIGNED: Boys\' and girls\' food habits are not motivated by the same factors. To create more effective dietary interventions targeting health promotion, unique motivations behind food habits need to be understood and incorporated.

UNASSIGNED: Substantial research on job motivation over the years has identified motivation to be essential to work outcomes such as wellbeing, attitudes, and performance. Yet, research on job motivation addressing temporal influences has been sparse. Existing research has addressed job motivation as an aggregation of the motivation for tasks, ignoring the possibility of temporal effects where the motivation for one task affects motivation in a subsequent task. The current meta-narrative review analyzes existing research on task motivation and synthesizes findings into a model of cross-task motivation.
UNASSIGNED: Using a predetermined search strategy, a systematic search yielded 1,635 documents of which 17 were selected. Papers were analyzed using a meta-narrative approach according to RAMSES publication standards.
UNASSIGNED: Four key meta-narratives were identified, contributing information from different research traditions; (1) restoration effects after need frustration, (2) intrinsic and extrinsic motivation, (3) cognitive carryover effects, and (4) meaning of work. Synthesizing findings from these meta-narratives, a meta-theoretical model for understanding cross-task motivation was proposed.
UNASSIGNED: This model provides an extension of existing motivational theories elucidating temporal motivational processes. Implications for practitioners include the possibility of arranging jobs to maximize positive motivational outcomes.

Retaining participants in clinical trials is an established challenge. Currently, the industry is moving to a technology-mediated, decentralized model for running trials. The shift presents an opportunity for technology design to aid the participant experience and promote retention; however, there are many open questions regarding how this can be best supported. We advocate the adoption of a stronger theoretical position to improve the quality of design decisions for clinical trial technology to promote participant engagement.
This study aimed to identify and analyze the types of retention strategies used in published clinical trials that successfully retain participants.
A systematic scoping review was carried out on 6 electronic databases for articles published from 1990 to September 2020, namely CINAHL, The Cochrane Library, EBSCO, Embase, PsycINFO, and PubMed, using the concepts \"retention,\" \"strategy,\" \"clinal trial,\" and \"clinical research.\" This was followed by an analysis of the included articles through the lens of self-determination theory, an evidence-based theory of human motivation.
A total of 26 articles were included in this review. The motivational strategies identified in the clinical trials in our sample were categorized into 8 themes: autonomy; competence; relatedness; controlled motivation; branding, communication material, and marketing literature; contact, tracking, and scheduling methods and data collection; convenience to contribute to data collection; and organizational competence. The trials used a wide range of motivational strategies. Notably, the trials often relied on controlled motivation interventions and underused strategies to support intrinsic motivation. Moreover, traditional clinical trials relied heavily on human interaction and \"relatedness\" to support motivation and retention, which may cause problems in the move to technology-led decentralized trials. We found inconsistency in the data-reporting methods and that motivational theory-based approaches were not evident in strategy design.
This study offers direction and a framework to guide digital technology design decisions for future decentralized clinical trials to enhance participant retention during clinical trials. This research defines previous clinical trial retention strategies in terms of participant motivation, identifies motivational strategies, and offers a rationale for selecting strategies that will improve retention. It emphasizes the benefits of using theoretical frameworks to analyze strategic approaches and aid decision-making to improve the quality of technology design decisions.
