Abstract

The dual-system model suggests that self-control and impulsivity coexist and regulate decision-making; however, this relationship has been scarcely studied in the context of consumer behavior in fast-fashion. In this regard, the present study investigates the role of self-control in impulsive buying, as well as the influence of intrinsic motivation, extrinsic motivation, and marketing actions in fast-fashion purchases. This study employed a descriptive, cross-sectional, and quantitative approach with a sample of 388 participants between 18 and 35 years of age. Exploratory and confirmatory factor analyses and the bootstrapping technique, were used to process the data and evaluate the proposed model. The results confirm that self-control acts as a regulatory mechanism between marketing stimuli, motivations, and impulsive behavior; nevertheless, its effect is partial and vulnerable to intense external stimuli. Likewise, the relationship between self-control and impulsive buying shows that, although consumers attempt to self-regulate, the fast-fashion environment encourages unplanned purchases. Finally, it is considered necessary to continue investigating the role of self-control in different contexts of impulsive buying and across diverse populations.

1. Introducción

The fashion market has experienced significant growth in recent decades. Women currently own approximately four times more clothing than they did in the 1980s (Sapper, 2018), while the fashion industry has nearly doubled its production capacity due to an annual demand growth rate of around 2% (Niinimäki et al., 2020). This increase in production has generated negative economic, social, and environmental impacts (Buzzo & Abreu, 2019; Reichart & Drew, 2019; Roozen & Raedts, 2020; Yoon et al., 2020; Bailey et al., 2022; Centobelli et al., 2022; Long & Nasiry, 2022), directly involving manufacturers, marketers, and consumers.

Consumers have increased their purchases of clothing, accessories, and textiles in response to marketing stimuli and social influences. This behavior is driven by marketing strategies (Chen, 2021; Kaczorowska-Spychalska, 2018; Zhang & Fong, 2020), including pricing tactics, rapid collection turnover, and advertising, as well as by cultural influences (Sari & Hanifah, 2018), social environments (Pop et al., 2023; Shao & Lassleben, 2021), and family contexts (Zhang et al., 2021). Additional factors such as fashion trends, lifestyles, self-concept, and aspirational goals also contribute to social and affiliative pressures that encourage consumption.

The growth of apparel production and the increasing tendency to purchase more garments have drawn attention to the fast-fashion industry and, specifically, to impulse buying. Impulse buying is a complex form of purchasing behavior (Wu et al., 2020) driven by stimuli that lead to spontaneous decisions, which are commonly observed in clothing purchases (Xiao et al., 2023). Fast fashion has been strongly associated with impulsive purchasing behavior (Gawior et al., 2022), particularly in online shopping environments, and is also related to consumers’ attitudes toward fast-fashion retailers (Cook & Yurchisin, 2017).

Nevertheless, consumers should not be viewed simply as agents who respond automatically to stimuli and increase their spending on clothing products. Purchasing behavior also involves awareness (Rahman et al., 2021), motivations (Kumar & Sadarangani, 2018), and self-control mechanisms (Efendi et al., 2019; Kaur & Singh, 2018), which enable individuals to assess their needs and regulate their purchasing decisions.

Awareness of the environmental and labour-related impacts of the fast-fashion industry can reduce positive consumer attitudes toward this sector (Roozen & Raedts, 2020). Concerns regarding the consequences of fashion consumption have encouraged the emergence of new approaches aimed at producing and consuming fashion with lower environmental and social impacts (Buzzo & Abreu, 2019). Consequently, companies have increasingly promoted sustainable fashion while simultaneously encouraging consumption, thereby creating an ambiguous discourse that fosters awareness of ethical consumption (Binet et al., 2019). However, such awareness does not always translate into actual purchasing behavior beyond a preference for natural and durable products (Zhang et al., 2021), since consumers are often driven by desire and personal satisfaction (Sapper, 2018).

Impulsive buying behavior and self-control are therefore fundamental variables for understanding the complexity of consumer behavior. Both are influenced by lifestyles (Dhewi & Azzahra, 2023), psychological factors, motivations, available resources, and marketing stimuli (Iyer et al., 2020). Consumers do not make purchasing decisions entirely without control; rather, they evaluate their decisions regarding apparel consumption. In this context, self-control refers to the ability to reduce or postpone purchasing desires (Horváth et al., 2015). It reflects the capacity to suppress undesirable desires or behaviors (Siswanti & Halida, 2020) and acts as a mediating factor between impulsivity and impulsive buying behavior (Dhewi & Azzahra, 2023; Iyer et al., 2020). Consequently, impulse buying tends to occur when self-control is weakened or insufficient (Victoria et al., 2021).

Previous research on consumer behavior has primarily focused on the food industry and financial decision-making (Francke & Carrete, 2023), with comparatively less attention given to the clothing sector (Iyer et al., 2020), and even less to the fast-fashion industry specifically. This gap has prompted further inquiries into the role of self-control in relation to variables such as price, advertising, personal selling, public relations (Francke & Carrete, 2023), and social media influence (Redine et al., 2023).

Considering demographic differences in consumer behavior, the importance of studying self-control in developing economies has been highlighted (Redine et al., 2023). Moreover, expanding research to include general consumers has been recommended, as many studies rely primarily on student samples (Francke & Carrete, 2023). Previous research has shown that self-control moderates fast-fashion purchasing behavior and influences the relationship between impulsivity and purchasing decisions (Xiao et al., 2023). However, the functioning of the dual-system model—which describes the coexistence of self-control and impulsive processes that regulate purchasing decisions in fast-fashion contexts—remains insufficiently understood.

Accordingly, the research question guiding this study is: How does consumer self-control mediate between stimuli and motivations in impulse clothing purchases? This research aims to address a gap in the existing literature on purchasing behavior in the fast-fashion industry, particularly regarding the role of self-control in impulse buying.

Therefore, the objective of this research is to describe how consumer self-regulation operates simultaneously with impulsive behavior in fast-fashion purchasing decisions.

Investigating the regulatory effect of consumer self-control in this purchasing process will contribute to the theoretical understanding of this phenomenon and provide practical insights for key stakeholders in the fashion industry, while also encouraging more conscious and sustainable consumption practices that benefit consumers.

2. Literature review and development of hypotheses

The fast-fashion strategy is characterized by the frequent renewal of clothing collections offered at relatively affordable prices (Centobelli et al., 2022). This accelerated production-and-sales process has evolved into the ultra-fast-fashion model, in which production cycles can be completed within only a few days (Camargo et al., 2020). These shortened cycles are driven by constant changes in trends, consumer tastes, and personal needs related to self-presentation within social environments. Such dynamics are further influenced by marketing stimuli motivated by a search for self-expression, confidence, and concern for personal image (Nunes & Silveria, 2016).

Fast-fashion purchasing behavior is commonly associated with impulsive buying, where emotions, sensations, hedonic value, consumer involvement, and promotional strategies play a significant role (Ngyen & Ha, 2021). However, some consumers have shifted from purchasing low-quality trend-based fashion toward seeking products with greater quality and durability (Gupta & Gentry, 2018). In addition, demographic factors such as age, monthly household income, and family size significantly influence expenditure on fast-fashion clothing consumption (Bishnoi & Guru, 2023).

The store environment also affects consumer perceptions (Taşkın & Bozbay, 2023). Stimuli can trigger impulse buying (Gupta & Gentry, 2018; Hashmi et al., 2020), while store design and layout are linked to loyalty (Anggara et al., 2023). Similarly, perceptions of store clutter and human crowding lead to perceptions of scarcity and competition (Ballantine et al., 2015; Coskun et al., 2020). Likewise, impulsive buying behavior and fast-fashion purchasing have been observed in online environments (Al Mutanafisa, 2021; Boardman et al., 2023; Fares et al., 2023; Luo et al., 2018).

At first glance, it may appear contradictory that consumers simultaneously exhibit self-control practices within fast-fashion purchasing contexts. Consumers may intentionally delay their purchases, waiting for promotional periods or more favorable purchase conditions (Jin et al., 2012). This behavior supports the notion that impulsive buying tends to occur when cognitive reflection is diminished, since failures in the self-control system can lead to impulsive actions (Müller et al., 2015).

However, the dual system theory suggests that self-control functions as a moderating variable between reactive and reflective processes (Moayery et al., 2019b). This perspective indicates that impulsive buying behavior and self-control coexist across a broad range of consumer behaviors (Sun et al., 2024), such as cell phones (Ding et al., 2022), internet addiction (Li et al., 2021a), financial management (Goyal et al., 2022), as well as online impulsive purchases of fashionable clothing items (Xiao et al., 2023). Despite these advances, research examining the role of self-control in fast-fashion consumption remains limited. Existing evidence is largely restricted to identifying a weak correlation between self-control and fast-fashion purchasing behavior (Syahidah & Suryawati, 2023).

2.1 Marketing stimuli, self-control, and impulse buying

Impulse buying has received considerable attention in consumer behavior research (Al Mutanafisa & Retnaningsih, 2021; Rodrigues et al., 2021). Consumers are frequently attracted by advertising and persuasive marketing messages, which are reflected in their purchasing behavior and intentions (Kollat & Willett, 2023). Advertising influences impulse buying behavior by generating stimuli that trigger immediate desires and needs (Iyer et al., 2020; Mittal et al., 2015). These stimuli may include offering discounts or promotions, creating a sense of urgency or scarcity, presenting products attractively, or using testimonials and positive recommendations (Gong & Jiang, 2023). Personal identity also motivates individuals to stay updated with the latest fashion trends and overspend (Rana & Malik, 2023).

Understanding consumer behavior and decision-making processes is essential for developing effective strategies capable of influencing consumer choices, particularly when self-control mechanisms mediate purchasing decisions (Xu et al., 2020). Marketing stimuli can significantly affect consumers' self-control and their tendency toward impulsive buying (Zheng & Alba, 2021). Sales promotions and advertising messages may stimulate impulsive purchasing behavior while simultaneously weakening self-control mechanisms (Moser, 2020). Marketing stimuli can also deplete self-control mechanisms and inhibit the generation of counterarguments, thereby contributing to a negative relationship between self-control and impulse buying (Sun et al., 2024).

However, self-control also moderates the relationship between marketing stimuli and the impulsive response system (Xu et al., 2020). The impulsive system is automatic and reactive, whereas the reflective system is controlled and inhibitory (Goschke & Job, 2023). Both systems operate in parallel (De Neys, 2021; Li et al., 2021b), with self-regulation moderating the influence of impulsive and reflective determinants on impulse buying. Nevertheless, the reflective system requires greater self-regulatory resources to function effectively (Moayery et al., 2019b).

Hypotheses:

2.2 The link between motivations, self-control, and impulse buying

According to self-determination theory, intrinsic motivation and autonomous forms of self-regulation are closely associated (Ryan & Deci, 2020). Intrinsic motivation refers to the internal drive derived from satisfaction obtained through engaging in an activity itself, whereas self-control refers to the ability to regulate and manage one's own thoughts, emotions, and actions. These mechanisms operate interdependently due to their close conceptual and behavioral relationship.

Impulse buying is a common consumer behavior that represents a substantial volume of goods and services across different product categories and geographical contexts (Iyer et al., 2019; Moayery et al., 2019a). It refers to the act of making unplanned purchases (Sohn & Ko, 2021), driven more by emotions, feelings, and attitudes than by rational decision-making (Ahmad et al., 2019; Lee et al., 2023; Santini et al., 2019). Motivation plays a significant role in impulse buying behavior (Erdem et al., 2021), and intrinsic motivation specifically influences this behavior (Lee, 2018; Sritanakorn & Nuangjamnong, 2021) through consumers' negative emotions (Luo et al., 2018).

Intrinsic motivation refers to the internal pleasure or satisfaction individuals experience when engaging in a particular activity without the need for external rewards or incentives (Hsu, 2022; Rheinberg & Engeser, 2018). In the context of impulse buying, consumers with high levels of intrinsic motivation are more likely to engage in impulsive purchasing behavior (Lavuri et al., 2022; Lee et al., 2021).

Extrinsic motivation refers to the influence of external factors on consumer behavior and decision-making processes (Fariana et al., 2021). These motivations encompass rewards, social pressures, and cultural norms (Aguiar, 2020). Such external factors may influence compulsive buying behavior through the moderation of self-control (Luo et al., 2018), potentially undermining an individual's ability to resist temptations or impulses to purchase unwanted or unnecessary products (Otero-López & Villardefrancos, 2015). Impulsive purchases may be triggered by both internal and external stimuli; however, self-control negatively moderates the relationship between these stimuli and impulsive buying behavior (Sun et al., 2024).

Extrinsic motivation is associated with behavioral adaptation in response to external pressure (Halfmann, 2021), thus representing self-control behavior. Previous studies have demonstrated that external stimuli can affect consistently or inconsistently planned impulse buying behaviors (Melati et al., 2024). Consumers with higher levels of self-control generally exhibit greater self-discipline, as they are more capable of regulating their thoughts and actions (Farmer et al., 2017). Such consumers are also more likely to delay gratification (Watson & Milfont, 2017; Yu et al., 2024) and adapt their purchasing habits by strengthening self-control in response to external influences (Gordon, 2021). However, they can also display impulsive buying behavior when self-control is low (Burton et al., 2018).

3. Methodology

This study adopts a descriptive, cross-sectional, and quantitative approach to examine how intrinsic motivation, extrinsic motivation, and marketing actions influence self-control and impulse buying. The target population consisted of men and women between 18 and 35 years of age residing in Bogotá. According to the National Department of Statistics (DANE), the population of Bogotá exceeds seven million inhabitants. However, for sampling purposes, the study considered a representative population framework.

The sample size was calculated using a 95% confidence level, a 5% margin of error, and a population proportion of 50% (p = 0.5), resulting in a minimum required sample of 384 participants. A non-probability convenience sampling method was employed, and a total of 388 respondents participated in the study.

Data were collected through a questionnaire distributed digitally via online channels, with voluntary participation. The instrument consisted of six sections. The socio-demographic section included nominal variables, whereas the sections related to impulse buying, intrinsic motivation, extrinsic motivation, marketing stimuli, and self-control contained variables measured using five-point Likert scales ranging from “completely disagree” to “completely agree,” as presented in Table 1.

For the development of the questionnaire, the researchers adapted established scales: Anand and Kaur (2018) for motivation, Malone et al. (2010) for self-control, Nakalinda (2018) for fast-fashion purchasing behavior, and Song et al. (2016) for marketing stimuli.

The data analysis process employed the statistical package SPSS Statistics version 27 for exploratory factor analysis (EFA) and descriptive analyses, as well as AMOS version 24 for confirmatory factor analysis (CFA) and structural equation modelling using the bootstrapping technique.

Data processing was based on Cronbach’s alpha, CFA, and structural equation modelling (SEM) analyses. Cronbach’s alpha was used to assess the internal consistency of the items within each factor. CFA enabled the evaluation of the fit between the observed data and the proposed theoretical structure, as well as the establishment of convergent and discriminant validity. In addition, SEM was employed to analyze the complexity of direct and indirect relationships among the study factors.

4. Results

The surveyed population was predominantly female (n = 184, 47.42%), followed by male participants (n = 161, 41.49%) and participants identifying with other gender categories (n = 43, 11.08%). Participants’ educational levels ranged from secondary education (n = 69, 17.8%) to university education (n = 183, 47.2%), university graduates (n = 122, 31.4%), and postgraduate education (n = 14, 3.6%).

Regarding income levels, the distribution was as follows: less than one Minimum Monthly Legal Wage (MLMW) (n = 60, 15.5%), between one and two MLMW (n = 145, 37.4%), between two and three MLMW (n = 140, 36.1%), between three and four MLMW (n = 29, 7.5%), and more than four MLMW (n = 14, 3.6%).

In terms of occupation, the majority indicated they were employed only (n = 218, 56.2%), followed by those studying and working (n = 115, 29.4%) and those studying only (n = 55, 14.2%).

The researchers conducted an exploratory factor analysis (EFA) using the principal component extraction method with varimax rotation, yielding acceptable values (KMO = 0.846, Bartlett's test of sphericity p < 0.001, X2 = 373.6, df = 175, p < 0.001). The findings indicated that the 21 items were clustered into five factors with factor loadings above 0.6, explaining 67.18% of the variance.

Based on these results, the researchers performed a confirmatory factor analysis (CFA), yielding X2 = 373.6, df = 175, p < 0.001, considering all factor loadings above 0.6. While some authors suggest a minimum criterion of 0.7 for factor loadings (Comrey & Lee, 1992; Tabachnick & Fidell, 2007; Yana et al., 2015), it is deemed acceptable in this type of study to have factor loadings starting from 0.6. The CFA results are displayed in Table 1.

Internal consistency reliability was assessed using Cronbach’s alpha. All constructs achieved values above the recommended threshold of 0.70, except for the self-control (SC) construct, which obtained an alpha of 0.645. This value can nevertheless be considered acceptable given the limited number of items comprising the construct.

Furthermore, alpha values ranging between 0.50 and 0.70 are considered moderate but acceptable in exploratory research, particularly when inter-item correlations exceed 0.30 (Hinton et al., 2004; Said, 2018; Wim et al., 2008). In this study, the SC construct demonstrated an average inter-item correlation of 0.48, supporting its internal consistency. Therefore, the reliability of the construct falls within an acceptable range (Hajjar, 2018; Nawi et al., 2020).

Regarding the composite reliability index (CR), values greater than 0.7 were obtained, excluding the SC construct, which showed a value of 0.657, considered acceptable according to the criteria proposed by Fornell & Larcker (1981) and Bagozzi & Yi (1988).

Similarly, the average variance extracted (AVE) showed values greater than 0.5. However, the intrinsic motivation (IM) and impulse buying (IB) constructs presented slightly lower values. Despite this, the criteria established by Fornell and Larcker (1981) and Henseler (2015) were satisfied.

To assess discriminant validity, the square root of the AVE was used as a reference, which proved to be greater than the correlations between each construct (Fornell & Larcker, 1981). Additionally, the values of the CFA results can be observed in Table 2.

4.1 Descriptive analysis

Regarding the goodness-of-fit indices, the absolute fit measures were assessed using the chi-square to degrees of freedom ratio (CMIN/DF = 2.135), the root mean square error of approximation (RMSEA = 0.054), along with the goodness-of-fit index (GFI = 0.916).

For the incremental fit measures, the analysis included the normed fit index (NFI = 0.906), non-normed fit index (TLI = 0.937), and comparative fit index (CFI = 0.947).

Lastly, the parsimony fit measures included the general parsimony goodness-of-fit index (PGFI = 0.694), normed parsimony fit index (PNFI = 0.755), and parsimonious comparative fit index (PCFI = 0.789), all yielding acceptable results according to the criteria outlined by Hu and Bentler (1999).

The researchers developed the causal model using structural equation modeling (SEM) with the bootstrapping technique for hypothesis testing, employing 2,000 sub-samples and a confidence level adjusted to 95%.

The path coefficients and significance levels indicate that hypotheses H1, H2, H4, H5, and H7 were supported, whereas hypothesis H3 was rejected, indicating that intrinsic motivation (IM) does not influence self-control (SC). Similarly, H6 was rejected, suggesting that extrinsic motivation (EM) does not influence impulse buying (IB). These findings are presented in Table 3.

However, the analysis of indirect effects revealed partial moderation in the relationship between marketing stimuli (MS) and impulse buying (IB) when self-control (SC) acts as the moderator (Direct effect = 0.502***, indirect effect = 0.045*).

Similarly, partial moderation is observed in the relationship between intrinsic motivation (IM) and impulse buying (IB) when self-control (SC) is the moderator (Direct effect = 0.279***, indirect effect = -0.18).

Conversely, moderation is absent in the relationship between extrinsic motivation (EM) and impulse buying (IB) when self-control (SC) is the moderator (Direct effect = 0.079, indirect effect = 0.026).

5. Discussion

This research contributes to understanding the operation of the dual-system model, where impulsive behaviors and self-control coexist. Although previous studies have examined this relationship (Iyer et al., 2020; Redine et al., 2023), there is still limited empirical evidence within specific sectors such as fast fashion using representative population samples (Francke & Carrete, 2023), except for Syahidah and Suryawati (2023), who reported a low relationship between these elements.

The findings confirm that marketing exerts a strong direct effect on impulsive purchasing (H1). The high statistical significance indicates that promotions, social media advertising, and seasonal campaigns stimulate fast-fashion consumption. Similar findings are consistent with Iyer et al. (2020), Gong & Jiang (2023), and Melati et al. (2024).

Despite the direct influence of marketing stimuli on purchasing behavior, such stimuli can also activate self-control mechanisms (H2). This relationship explains that marketing stimuli interact with the consumer's reflective system (Zheng & Alba, 2021), which requires self-regulation resources to inhibit automatic responses (Goschke & Job, 2023). Consequently, practices such as limiting purchases to a predetermined budget or restricting purchases to explicit needs may reduce the impact of promotional activities on purchasing behavior.

Although previous studies have demonstrated that promotions and advertising messages can directly trigger impulsive purchases or weaken self-control (Moser, 2020), the present findings indicate that self-control moderates this relationship by activating reflective processes that counteract the initial impulse (Xu et al., 2020). This finding highlights that the dual-system model operates through parallel processes (De Neys, 2021; Li et al., 2021b).

Intrinsic motivations demonstrated a significant effect related to impulsive purchasing (H4), as reported by Erdem et al. (2021), Lee (2018), and Sritanakorn & Nuangjamnong (2021), who concluded that identity construction and the pursuit of authenticity influence purchasing decisions. Therefore, individuals with higher levels of intrinsic motivation may be more likely to engage in impulsive buying, particularly when products are acquired to enhance self-esteem, image, and status (Wicklund & Gollwitzer, 1982), or to remain aligned with current trends (Rana & Malik, 2023). Similar behavior has also been associated with hedonic and materialistic motivations (Lavuri, 2023).

In contrast, the absence of a relationship between intrinsic motivations and self-control (H3) demonstrates that self-expression and pleasure may hinder the activation of control mechanisms. This finding contradicts the results reported by Wang et al. (2024), who identified self-control as a mechanism linking materialism with the reduction of risk behaviors. Likewise, Roberts and Manolis (2012) suggested that consumers experiencing conflicting desires may become more susceptible to impulsive purchasing behavior.

Extrinsic motivation was found to influence self-control (H5), indicating that social factors trigger regulatory behaviors. External factors such as social pressures or cultural norms may influence a person's ability to regulate and resist impulsive buying temptations and likely affect individuals' ability to control their buying impulses (Fares et al., 2023; Nguyen & Ha, 2021).

As a result, self-control demonstrated a moderating effect on impulsive purchasing (H7); however, its impact was limited and appeared to depend on both social stimuli and personal motivations. Although self-control reduces impulsive behavior, its effect does not completely suppress such conduct, and consumers may rationalize their decisions. Similar research conducted in other contexts identifies self-control as a negative moderating variable in impulsive purchasing (Luo et al., 2018; Melati et al., 2024; Mittal et al., 2015; Pradipto et al., 2016; Ramadan et al., 2021; Roberts & Manolis, 2012). Nevertheless, although it acts negatively, fast-fashion purchasing behavior increases impulsive levels, which are difficult to resist.

Iyer et al. (2020) examined the mediating effects of self-control between impulsive buying, marketing stimuli, and both internal and external motivations through a meta-analysis. The authors found consistent results regarding the positive influence of stimuli on impulsive buying regardless of self-control mediation. However, they also identified an indirect effect between self-control and impulsive buying.

Finally, no direct evidence was found to support the hypothesis that extrinsic motivations influence impulsive behavior (H6), indicating that social and cultural pressures do not always promote the impulsive purchase of clothing. These results may appear contradictory because Amaral and Djuang (2023) identified a relationship between social aspects and purchase intention but isolated the relationship between extrinsic motivations and impulsive buying, while Chowdhury (2020) established this relationship but did not consider the mediating effect of self-control in garment purchasing.

5.1 Theoretical contributions

The main contribution of this research highlights that self-control exerts a partial mediation between marketing stimuli, motivations (both intrinsic and extrinsic), and impulsive purchasing behavior. This finding emphasizes that consumers regulate their clothing purchases in a context where impulsive buying is the predominant behavior. This dynamic demonstrates the coexistence of both intuitive and analytical behavior, suggesting that consumer behavior in this industry operates under the parameters of the dual-system model.

The acceptance that, in fast-fashion purchasing behavior, some sources of motivation are processed by the control system while others are not suggests that self-control is not an immutable trait, but rather a mechanism that can be modulated by external factors. However, its moderating effect is suppressed when behavior is driven by motives related to identity and self-expression.

Several aspects demonstrate this modulation process. On the one hand, self-control operates when individuals evaluate marketing stimuli and the social environment before deciding to purchase. On the other hand, self-control mechanisms appear to be less effective when personal motivations —such as the desire for authenticity or the pleasure associated with purchasing clothing— become predominant.

5.2 Limits and future directions

This research does not discriminate between subjects. Future research may establish relationships between gender, degrees of propensity for impulsive buying, and the effectiveness of control mechanisms to determine whether these mechanisms are triggered by the factors described above.

Although the consumer profiles included in this research extend beyond student samples, demographic, cultural, and economic limitations remain. These factors may affect the generalization of the results. Future research could therefore develop intercultural studies across different Latin American countries and compare consumer behavior between developed and developing economies to determine whether levels of self-control (high, medium, low) affect the interaction between the impulse and stimulus systems in fast fashion.

5. Conclusions

This research contributes to a deeper understanding of how self-control mediates the relationship between marketing stimuli, motivations, and impulsive purchasing behavior in the fast-fashion industry. The findings indicate that self-control is not a fixed or immutable trait, but rather a mechanism influenced and modulated by external factors. The study emphasizes the complexity of consumer behavior in fast fashion, demonstrating the ongoing interplay between impulsive and reflective processes in purchasing decisions.

The results provide further insight into the operation of the dual-system model in fast-fashion purchasing, specifically regarding the interaction between control mechanisms and impulsive behavior. The self-control system partially moderates purchasing behavior when consumers are influenced by advertising strategies or social motivations, demonstrating a reflective process. However, this moderating effect appears to weaken when clothing purchases are driven primarily by personal interests, demonstrating an impulsive process. This dynamic highlights the coexistence of both intuitive and analytical systems within consumer behavior.

Intrinsic motivations were found to directly influence impulsive behavior, suggesting that consumers with higher levels of intrinsic motivation may be less likely to exercise self-control in certain purchasing situations. Personal desires related to authenticity and pleasure correspond with impulsiveness in purchases that are not based on explicit needs. This impulsiveness is reflected in emotionally driven behaviors and openness to change, such as the need to buy something, purchasing due to seasonal changes or brand novelties, and the pursuit of immediate gratification or the desire to seize momentary opportunities.

Extrinsic motivation, such as social pressure and cultural norms, may also influence individuals' ability to control their buying impulses. However, these motivations did not have a direct relationship with impulsive buying, suggesting that social and cultural motives do not always drive impulsive clothing purchases. Nevertheless, the indirect effect between extrinsic motivation and impulsive buying, mediated by the self-control system, facilitates impulsive behavior. This highlights the need for further research on whether self-control reinforces social motivations as a pretext for acting impulsively.

Finally, the findings confirm that consumer behavior in this scenario is strongly driven by promotions, social media advertising, and seasonal campaigns, but it is moderated when consumers activate reflective processes in their purchase decisions, thereby regulating impulsive behavior. The presence of self-control affects marketing efforts and their impact on impulsive buying by diminishing such behavior, as it weakens the relationship. In the absence of such mediation, impulsive purchasing behavior tends to increase significantly.
