A full-factorial test of motivational and volitional intervention strategies for promoting exercise habit formation and exercise maintenance among new users of an online exercise class platform.

Interventions often fail to achieve long-term behavioral maintenance. Utilizing motivational and volitional strategies to promote behavioral maintenance factors may improve this. Using a full-factorial experiment, we tested the effects of three intervention components (focused on intrinsic motivation and identity, exercise preparation habit, and exercise instigation habit) on exercise participation over a year, among new users (N = 751; 91% identifying as female, 54% identifying as White race) of a global, online exercise class platform, run by Les Mills International Ltd, called LM+. We also tested the intervention components' theoretical mechanisms of action-habit formation, intrinsic motivation, identity, and self-efficacy. Multi-level models found some support for a main effect of the exercise preparation habit intervention component in promoting self-reported and objective exercise participation (behavioral outcomes measured via monthly surveys and the LM+ platform; mechanisms measured via monthly surveys)-in particular online exercise class frequency (fixed effect estimate = 0.84, p < 0.05, and = 0.12, p < 0.05, respectively). The preparation habit component also significantly increased preparation habit strength (0.30, p < 0.05) and instigation habit strength (0.33, p < 0.05). Other expected effects were nonsignificant. Helping individuals form an exercise preparation habit may facilitate initiating and maintaining exercise over time, in particular for attending online exercise classes, potentially through promoting greater preparation and exercise instigation habit strength.

Feasibility and Engagement of a Mobile App Preparation Program (Kwit) for Smoking Cessation in an Ecological Context: Quantitative Study.

BACKGROUND: Mobile health apps can facilitate access to effective treatment and therapeutic information services. However, the real-world effectiveness of mobile apps for smoking cessation and their potential impact in everyday settings remain unclear. OBJECTIVE: In an ecological context, this study aimed to estimate the engagement rate of a mobile app-based smoking cessation preparation program and its potential impact on users' willingness, ability, and readiness to quit smoking. METHODS: A total of 2331 "organic users" (ie, users who discover and install a mobile app on their own, without any prompts) chose 1 of 2 program versions of the mobile app (Kwit): the basic version or the premium version. Both versions were identical in design, with 4 more evidence-based content items and strategies in the premium version. Outcomes were analyzed based on automated data registered in the app (engagement rate, motivation to quit, motivation type, motivation levels, and satisfaction level). Mann-Whitney and χ2 tests were used to compare the results of both groups. RESULTS: As expected, in the ecological context, a high dropout rate was observed at different moments. A significant difference was observed between the 2 versions (n=2331; χ21=5.4; P=.02), with a proportionally higher engagement rate in the premium version (premium=4.7% vs basic=2%). Likewise, differences were also observed between the 2 groups in terms of reasons to quit (n=2331; χ24=19; P≤.001; V=0.08), motivation type (n=2331; χ27=14.7; P=.04), and motivation level. Users of the app's premium version more frequently reported "well-being" (23.3% vs 17.9%) and "planning a pregnancy" (7.4% vs 4.4%) as their primary reasons for quitting smoking compared to those with the basic version. Moreover, they reported being more likely to be driven in the smoking cessation process by intrinsic motivation (premium=28% vs basic=20.4%), as well as feeling significantly more willing (z score=156,055; P≤.001; Cohen d=0.15), able (z score=172,905; P=.04; Cohen d=0.09), and ready (z score=166,390; P=.005; Cohen d=0.12) to stop smoking than users who had the basic version before completion of the preparation program. Among participants who finished each version of the program (premium: 9/189, 4.8%; basic: 47/2142, 2.19%), significant improvements in motivation levels were observed in both groups, although in different areas for each group (willingness levels for the premium group and ability for the basic group). CONCLUSIONS: These results suggest that even in ecological contexts where engagement rates are meager, the Kwit preparation program can address ambivalence by increasing willingness to change, self-confidence, and readiness to quit among its users, especially those who feel less able to do so. Further development and evaluations are needed to better understand determinants for regular mobile health apps.

What motivates early lies? Deception in 2½- to 5-year-olds.

What motivates young children to produce early lies? A total of 217 2½- to 5-year-old children (Mage = 44.5 months, SD = 8.45; 54% girls; 61.7% White) from the southeastern United States were tested using a modified third-party transgression paradigm to examine the motivation behind their deception. Children were assigned to one of three conditions-baseline, self-motivated, or other-motivated condition-and their propensity to lie was captured through both verbal and nonverbal measures. Results show that children's early lies are primarily driven by a self-serving motivation. However, the motivation to lie diversifies by 4 years of age, when children begin to lie for both self-serving and other-serving motivations.

Psychosocial determinants of handwashing and physical distancing behaviour during the COVID-19 pandemic in the Netherlands: A longitudinal analysis.

OBJECTIVES: Physical distancing and handwashing can be important infection prevention measures during an infectious disease outbreak such as the COVID-19 pandemic. To stimulate these behaviours, knowledge of psychosocial determinants as well as contextual factors is vital. We present longitudinal, within-person analyses of the impact of contextual and psychosocial factors on handwashing and distancing behaviour. DESIGN: We used individual-level data (186,490 participants completing 971,899 surveys) from the Corona Behavioural Unit COVID-19 Cohort, a dynamic cohort study conducted during 26 months of the COVID-19 pandemic in the Netherlands. METHODS: Fixed-effects models were employed to estimate within-person associations between psychosocial factors and behaviour, combined with main and moderating effects of contextual factors. RESULTS: Pandemic severity was associated with more handwashing and distancing behaviour, while the duration of the pandemic had little effect. Within-person changes in response efficacy were most relevant for changes in both handwashing and distancing behaviour, while self-efficacy, descriptive norms and perceived severity of infecting others affected behaviour indirectly. These effects were stable over time. Associations were larger in cross-sectional models, indicating that such models tend to overestimate effects. CONCLUSIONS: Our study highlights the importance of longitudinal data and within-person models to detect possible causal associations. The results suggest that during an outbreak, government and public health professionals should clearly communicate the severity of the pandemic (e.g., hospitalization rates) and the effectiveness of recommended prevention measures in reducing that risk; and seek to improve people's capabilities and opportunities to adhere to guidelines, for example, by modifying the environment.

The effect of language learning engagement on L2 motivation over Instagram.

This study investigated the relationship between English language learners` Instagram engagement and second language (L2) motivation. It also aimed to determine engagement types (behavioral, cognitive, and affective engagement) as predictors of L2 motivation. Through stratified sampling, we recruited 102 Iranian users engaged in learning English via the Instagram platform as an informal learning context. The participants were Persian native speakers learning English as a foreign language. They were 81 males and 21 females at different levels of English proficiency whose ages ranged from 16 to 62. A multimethod approach, with a quantitative/qualitative design, was adopted to conduct the study. The quantitative phase had a correlational design in which two questionnaires were administered to measure English learners` engagement in language learning on Instagram and their L2 motivation. Furthermore, a semi-structured interview was conducted in the qualitative phase. Results revealed a positive and significant relationship between the English language learners` engagement on Instagram and their L2 motivation. Moreover, cognitive engagement was the sole predictor of learners` L2 motivation. The findings have pedagogical implications for both English instructors and L2 learners, which are discussed in light of the literature.

Effects of perceived variety-support on middle school students' learning engagement in physical education: the mediating role of motivation.

Introduction: High engagement in physical education (PE) could effectively develop students' motor competence and promote physical activity, which was significantly important for students' physical and mental health. Researches had shown that motivation was an important factor in explaining students' learning engagement, and variety-support as the fourth independent psychological need was a potential factor influencing students' learning motivation. However, there was a lack of empirical research evidence on the effect of perceived variety-support on middle school students' learning engagement in PE and the influencing mechanisms. This study aimed to investigate the direct effect of perceived variety-support on learning engagement in PE and the mediating effect of motivation in PE on the relationship. Methods: A cross-sectional study was conducted and 587 middle school students from Liaoning province filled the paper-and-pencil questionnaires adopting perceived variety-support in PE scale (PVSPES), utrecht work engagement scale-student (UWES-S), and perceived locus of causality in PE scale, which had been proved to have good reliability and validity (294 boys and 293 girls, Mage=13.47 ± 0.94). Results: The results showed three variables were significantly positively correlated with each other (r = 0.323-0.562 p < 0.01) and perceived variety-support in PE could not only directly promote middle school students' learning engagement in PE but also indirectly through the mediating effect of motivation in PE. Discussion: Therefore, in order to better promote students' participation in PE class, we should pay more attention to satisfy students' varied PE learning needs and stimulate students' autonomous learning motivation.

Delving into the role of reward and punishment sensitivity in anorexia nervosa: Punishment responsivity as the only predictor of eating disorder symptom persistence in adolescents.

OBJECTIVE: This study differentiated between self-reported punishment responsivity (PR) and motivation to avoid punishment (MP) and examined their relationship with anorexia nervosa (AN) and its course in a combined cross-sectional and longitudinal approach. We explored whether inconsistent findings regarding reward sensitivity may be explained by previous research not differentiating between reward responsivity (RR) and motivation to approach reward (MR). METHOD: Participants were 69 adolescents with AN and 69 adolescents without AN matched on age, sex and educational level. Eating disorder (ED) symptom severity, PR, MP, RR, and MR were assessed at the start of treatment and 1 year later. RESULTS: Only PR was higher in patients with AN than in the comparison group. Both PR and MP decreased over the course of 1 year, however, only the reduction in PR was related to the reduction in ED symptoms. Lastly, only higher baseline PR was independently related to less improvement in ED symptoms over the course of 1 year. CONCLUSION: There was no support for the involvement of RS or its specific dimensions in AN. Most critical, the findings suggest that specifically the PR dimension of punishment sensitivity is related to the persistence of AN and could be an important target for treatment.

High immersion/escapism motivation makes gaming disorder risk less dependent of playtime among highly engaged male gamers.

In the realm of gaming-related concerns, the relationship between gaming time (GT) and gaming disorder (GD) remains an intriguing and complex subject. Although increased GT is not a reliable predictor of GD risk, the circumstances under which this relationship strengthens or weakens remain relatively unknown. This study explores the roles of immersion/escapism motive (IEM) and GT in the context of GD among highly engaged gamers (N = 294), each dedicating a minimum of 20 hours weekly to gaming. The findings confirm that IEM significantly moderates the relationship between GT and GD in the male sample. Specifically, low and moderate levels of IEM result in a stronger relationship between GT and GD. In the case of women, the effect was not significant. These findings suggest the importance of comprehensive assessments of gaming motivations when addressing gaming-related issues, particularly in GD research. Moreover, they emphasize the value of adopting a complex approach to comprehending the development of problematic gaming behaviors.

Algorithmic management and human-centered task design: a conceptual synthesis from the perspective of action regulation and sociomaterial systems theory.

This paper aims to explain potential psychological effects of algorithmic management (AM) on human-centered task design and with that also workers' mental well-being. For this, we link research on algorithmic management (AM) with Sociomaterial System Theory and Action Regulation Theory (ART). Our main assumption is that psychological effects of sociomaterial systems, such as AM, can be explained by their impact on human action. From the synthesis of the theories, mixed effects on human-centered task design can be derived: It can be expected that AM contributes to fewer action regulation opportunities (i.e., job resources like job autonomy, transparency, predictability), and to lower intellectual demands (i.e., challenge demands like task complexity, problem solving). Moreover, it can be concluded that AM is related with more regulation problems (i.e., hindrance demands like overtaxing regulations) but also fewer regulation problems (like regulation obstacles, uncertainty). Based on these considerations and in line with the majority of current research, it can be assumed that the use of AM is indirectly associated with higher risks to workers' mental well-being. However, we also identify potential positive effects of AM as some stressful and demotivating obstacles at work are often mitigated. Based on these considerations, the main question of future research is not whether AM is good or bad for workers, but rather how work under AM can be designed to be humane. Our proposed model can guide and support researchers and practitioners in improving the understanding of the next generation of AM systems.

The affective response to positive performance feedback is associated with motor learning.

Motor skill learning and performance are improved when successful actions are paired with extrinsic rewards, such as money. Positive feedback indicating successful task performance is thought to induce intrinsic reward associated with goal attainment, evidenced by increases in positive affect that correlate with neural reward signaling. However, it is not clear whether the subjective, internal reward processes elicited by positive feedback promote motor learning and performance.Here, we tested the hypothesis that intrinsic reward elicited by positive feedback promotes motor learning and performance. Participants practiced a visuomotor interception task using a joystick, and received feedback during practice indicating success or failure depending on their accuracy. During practice, the accuracy demands were adapted to control and vary the frequency of positive feedback across randomly ordered blocks of practice at either 50%, 70%, or 90%. Performance was measured for each condition as the average accuracy during practice. Learning was estimated by measuring the accuracy pre and post practice in the absence of feedback. We queried participants periodically on their enjoyment of the task to index affective responses to performance feedback.The intrinsic reward elicited by positive feedback, operationalized by the increase in enjoyment immediately following positive versus negative feedback, was positively correlated with learning from pre to post practice. However, increasing the overall amount of positive feedback by lower accuracy demands did not improve performance. These results suggest that experiencing intrinsic reward due to positive feedback benefits motor learning only when it is contingent on good performance.

Assessing motivational biases in brain and behavior: Event-related potential and response time concomitants of the approach-avoidance task.

The approach-avoidance task (AAT) is designed to measure implicit motivated action biases instantiated by emotional stimuli and alterations in such biases that drive psychiatric disorder. While some research has measured AAT event-related potential (ERP) correlates to establish bias sensitivity even at a neural level, a lack of work with unpleasant, pleasant, and neutral stimuli together and a common focus on psychiatric disorder-matched (rather than generally emotional) content limits conclusions that can be drawn. Thus, current work extends the AAT literature by testing ERP modulations across normatively unpleasant, pleasant, and neutral conditions; and supporting the task's use as an individual difference assessment, it also provides data on AAT reliability and initially explores anxiety-related effects when stimuli are not disorder-matched. In 38 participants including 19 anxiety treatment-seeking individuals, 32 sensor electroencephalography revealed robust N100, N200, and late positive potential (LPP) ERP components and bias-consistent modulations for unpleasant images (reduced N200s on unpleasant push relative to pull trials; enhanced LPP for unpleasant compared to neutral trials). Meanwhile, modulations were less consistent with emotion-driven bias for other conditions-that is, LPPs were enhanced but N200 was not modulated for pleasant images, and for neutral images, N200 was unexpectedly enhanced on push compared to pull trials. Following these analyses, reliability tests revealed excellent raw ERP reliabilities but lower reliabilities for modulation scores, and comparing treatment- to non-treatment-seeking groups showed no preliminary indication of ERP modulation changes when stimuli are not personally relevant. How these findings together inform understanding of AAT as a measure of bias is discussed.

Applying a Motivational Instructional Design Model to Stroke Rehabilitation: A Feasibility Study on Occupational and Swallowing Therapies.

Objective: To investigate the feasibility of poststroke interventions using a motivational instructional design model with occupational therapy (OT) and swallowing therapy (ST) and the model's potential physical and mental health effects. Design: An open-label, single-arm, feasibility study on the Attention, Relevance, Confidence, and Satisfaction model. Setting: Two convalescent rehabilitation wards. Participants: Twenty-five patients with stroke (N=25) (19 men; mean age, 62.4±11.9y; 61.9±36.8d from the first stroke) were recruited. Interventions: Twelve participants received a motivational approach based on the Attention, Relevance, Confidence, and Satisfaction model during OT (OT group), and 13 received it during ST (ST group). The intervention lasted 40-60 minutes daily, 5 days weekly, for 4 weeks. Main Outcome Measures: The primary outcomes included the dropout rate, an adverse event, and the participants' acceptability of the intervention. Paretic arm function was assessed in the OT group; swallowing ability was assessed in the ST group; and activities of daily living, depressive symptoms, and apathy were assessed in both groups. Results: No participants dropped out of the intervention or experienced an adverse event. Twenty-one participants (84%) were satisfied with the intervention, and 19 (76%) hoped to continue receiving it. The OT group showed statistically significant improvements in paretic arm function and activities of daily living (Cohen's r=0.68-0.77), whereas the ST group improved in swallowing ability, activities of daily living, and depressive symptoms (Cohen's r=0.62-0.85). Conclusions: The interventions using the motivational instructional model with OT and ST were feasible and could improve poststroke paretic arm function, swallowing ability, and activities of daily living after stroke.

Application of SBIRT Tools in Managing Alcohol and Drug Use Disorders.

BACKGROUND: To evaluate the eligibility and feasibility of the "Voice Modules in Narcology" (VMIN) program. MATERIAL AND METHODS: We developed a computer program to screen for risky alcohol or drug use, utilizing an interactive voice assistant as a motivational component. Given the low detection of such risks during population health examinations and medical check-ups, this program could allow the primary healthcare sector to expand screening coverage for risky alcohol and drug use without additional medical personnel. VMIN includes an anonymous short questionnaire (CAGE) and a question about drug use, offering a short (3-4 minutes) voice file with motivational information encouraging specialist consultation if risks are detected. The program also assesses the usefulness of the information received and the readiness to consult a narcologist for diagnosing substance use disorders. 51 outpatients under treatment at Samara State Medical University Hospital were included in the pilot project for evaluation the eligibility and feasibility program. RESULTS: 11 patients (21.6%) who were identified as at risk of alcohol or drug consumption listened to the voice modules after screening. Among these, 8 (72.7%) respondents provided feedback: 8 (72.7%) respondents found the information useful, 5 (45.5%) expressed willingness to change their behavior to reduce substance or alcohol use, 2 (18.2%) expressed readiness to seek specialized help, and 1 (9.1%) provided contact information for follow-up assessment of substance or alcohol use risk. CONCLUSIONS: A significant proportion of patients in multi-profile hospitals' cardiology and gastroenterology units (21.6%) reported risky alcohol consumption; drug use was reported by one man (1.9%). The majority of respondents who listened to the voice modules considered the provided information useful, but only one (1.9%) shared contact information for the follow-up assessment, and 3 (27.3%) did not give feedback. The high proportion of individuals giving positive feedback provides preliminary support for the feasibility of the method.

Psychosocial determinants of alternative protein choices: a meta-review.

This meta-review synthesises evidence concerning individual-level psychosocial characteristics associated with alternative protein food (APF) choices. We investigated the associations between: (i) individual-level determinants based on the COM-B model (capabilities, perceived opportunities, motivation), sociodemographic factors, and (ii) indicators of APF choices (e.g., intention to eat, buy, pay, acceptance, intake). Differences in characteristics of APF made from plants, insects, mushrooms, and other APF sources were explored. Thirteen databases were searched in this pre-registered (CRD42023388694) meta-review and 28 reviews were included. The risk of bias was assessed using the ROBIS tool. For plant-based APF choices, consistent support was obtained for associations with (i) capabilities, including cooking skills, exposure to/familiarity with APF; (ii) motivations, including perceived health-related, pro-environmental, and sustainability benefits, and animal welfare; (iii) younger age and higher education. For insect-based APF choices, consistent support was obtained for (i) capabilities, including formal knowledge about APF, exposure to/familiarity with APF; (ii) perceived opportunities, encompassing positive social and cultural norms, distrust in technology; (iii) motivations, including perceived health benefits, pro-environmental and sustainability benefits, perceived health risks, being adventurous/daring, curiosity, neophilia, disgust; (iv) male gender and younger age. Recognising differences in potential determinants across various APF sources is essential for designing interventions aimed at promoting APF uptake.

Is prior bullying victimization associated with subsequent bullying perpetration? A theoretical framework based on the Threat-Motivation model.

INTRODUCTION: Bullying among adolescents is a global public health issue prevalent in schools, posing significant risks to positive adolescent development. Studies have shown that bullied adolescents tend to engage in more bullying perpetration, but this underlying process of longitudinal correlation has not been fully elucidated. METHODS: Based on two waves of longitudinal data collected from 347 junior and 144 senior high school students in China (Mage = 13.66 years, SDage = 1.46, 59.27% boys) at 1-year intervals, two moderated chain-mediation models were used to explore the longitudinal correlations between bullying victimization and bullying perpetration and its underlying processes. RESULTS: The results found a significant positive correlation between adolescents' bullying victimization experiences 1 year prior and bullying perpetration 1 year later. Furthermore, fear of negative evaluation and psychache played a longitudinal chain-mediating role in the process, with self-esteem and grade moderating this mediating pathway, either enhancing or weakening the effect. CONCLUSIONS: This study demonstrates that prior bullying victimization is longitudinally and positively associated with subsequent bullying perpetration among adolescents. This process is mediated by fear of negative evaluation and psychache, with self-esteem and grade level as moderators. Based on these conclusions, we have formulated the Threat-Motivation Model, offering a framework to understand the relationship between bullying victimization and bullying perpetration. Practical implications, including strategies to reduce bullying in youth groups, are discussed.

Teaching for transfer of learning in health professions education: AMEE Guide No. 176.

Transfer of learning occurs when past learning is applied to new situations, and also at a varying time from the initial time of learning. Importantly, research in both academic and clinical areas of health professions education has highlighted that transfer of learning often does not successfully occur. Successful transfer is multi-dimensional and occurs when the learner has the required motivation, mental model, metacognitive processes relevant to the task, and the opportunity to transfer their learning to different situations. An essential aspect of successful transfer is the educator. This Guide provides an overview of an integrated model of transfer that can inform a variety of practical teaching strategies in both academic and clinical areas of health professions education.

Differences in motivational dynamics between experienced cyclists and untrained participants during an incremental endurance exercise task.

PURPOSE: The conflict between the desire to reduce effort during exercise and the performance goal of the exercise task contributes to explaining endurance exercise performance. However, whether the trajectories of these two motivational responses systematically differ across individuals with different characteristics is poorly understood. The present study examined whether changes in desire to reduce effort and performance goal value across moderate, heavy, and severe exercise intensity domains differed between cyclists and untrained, but active participants. METHODS: Fifty participants (14 cyclists and 36 untrained) completed an incremental step test on a cycle ergometer, in which work rate was increased by 25 W every 4 min until voluntary exhaustion. Desire to reduce effort, performance goal value, and blood lactate concentration (for determination of exercise intensity domains) were measured every 4 min and the data were analysed using multilevel modelling. RESULTS: Desire to reduce effort increased quicker for untrained participants in the moderate exercise intensity domain (b = 1.66, p < .001) and across the whole trial (b = 1.64, p < .001), compared to cyclists (b = .69, and b = 1.14, respectively, both p < .001). Untrained participants reported similar performance goal value at the beginning of the trial (b = 16.02, p < .001), compared to cyclists (b = 17.25, p < .001). Beyond moderate intensities, the performance goal value decreased significantly for the untrained participants (b = -.70, p < .001) but significantly increased for cyclists (b = .45, p = .01). This pattern was also observed when focusing solely on the severe intensity domain (cyclists: b = .90, p < .001; untrained: b = -.84, p < .001). CONCLUSION: There are distinct differences in the desire to reduce effort and performance goal value between cyclists and untrained athletes. Identifying these systematic differences enhances the credibility of the desire-goal conflict framework in explaining endurance performance and provides insight into the type and timing of interventions that might be successful in improving performance.

Mounting exhibited between cows is not associated with sexual motivation.

Females of various species exhibit mounting behavior toward other mature females, i.e., female-female (f-f) mounting. Cows exhibit f-f mounting, which is commonly considered a sexual behavior based on a few similarities with male sexual mounting. Here, we hypothesized that the degree of f-f mounting exhibited by cows in estrus would increase when they are sexually motivated by sexually relevant stimuli. To test this hypothesis, two groups of four cows each were prepared. First, estrus was induced in one of the cows in each group by injecting estradiol in the presence of a non-sexually active male steer as a stimulus animal (steer-stimulus condition), and all f-f mounts were recorded. Estrus induction was repeated until induced in all cows. We then changed the stimulus animal from the steer to a sexually active bull (bull-stimulus condition), and the estrus induction procedures were repeated as before. We confirmed that estrus was induced successfully in cows injected with estradiol and that they were sexually motivated by switching the stimulus animal from steer to bull, as they spent relatively more time with the stimulus animal in the bull-stimulus than in the steer-stimulus condition and when not in estrus. However, f-f mounting frequency in the bull-stimulus condition showed no significant difference to that in the steer-stimulus condition. We observed that six of the eight subjects exhibited f-f mounting when not in estrus, which accounted for 44.6 % of f-f mounting we observed (n = 668). These findings suggest that f-f mounting in cows is not associated with sexual motivation.

Cultural adaptation and psychometric evaluation of the Persian version of the motivation for nursing student scale (MNSS).

BACKGROUND: Motivation is a critical factor in the success of nursing students, as it significantly influences their ability to acquire the necessary knowledge and skills for the nursing profession. Insufficient motivation can result in a lack of engagement with learning activities, thereby impeding the development of essential competencies. AIM: This study aimed to translate the Motivation for Nursing Student Scale (MNSS) into Persian and evaluate its psychometric properties within the context of nursing students in Iran. METHOD: This methodological cross-sectional study involved a sample of 542 nursing students selected through convenience sampling. The MNSS was translated into Persian following the guidelines recommended by the World Health Organization. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and assessments of internal consistency were conducted to evaluate the validity and reliability of the instrument. RESULTS: The EFA and CFA validated the structure of the instrument, identifying four factors and 20 items, which explained 58.68% of the total variance. The CFA results indicated a well-fitting model with the following indices: CFI = 0.91, GFI = 0.93, IFI = 0.946, TLI = 0.92, RMSEA = 0.061, and SRMR = 0.049. The Cronbach's alpha coefficient and Intraclass Correlation Coefficient (ICC) for the scale were 0.882 and 0.802, respectively. CONCLUSION: The Persian version of the MNSS demonstrates satisfactory reliability and validity, making it a dependable instrument for measuring the academic motivation of nursing students. This tool can be effectively used to assess the motivation of nursing students in Iran.
