Introduction Young adults, particularly university students aged 18 to 24, are undergoing a critical period in their personal and financial development. This transitional stage is characterized by increasing responsibilities in managing personal finances, including budgeting, saving, and making informed financial decisions. Although access to financial services has expanded significantly, many students continue to experience difficulties related to overspending and inadequate financial planning. According to the 2024 financial literacy survey conducted by IndonesiaAos Financial Services Authority (Otoritas Jasa Keuangan/OJK), the national financial literacy index reached 65. indicating substantial room for improvement, particularly among the youth segment (Ana, 2. Consumerist behavior has become increasingly prevalent among university students, driven by social lifestyle expectations and the convenience of digital payment Frequent cafy visits, impulsive online shopping, and reliance on short-term credit reflect limited financial self-control and weak long-term financial planning. The rapid growth of digital financial services, including buy now pay later (BNPL) schemes and peer-to-peer lending platforms, has further intensified these challenges. As of June 2024. OJK reported that the total value of online loans in Indonesia reached IDR 47 trillion, with Generation Z . ged 12Ae. accounting for IDR 26. 87 trillion. Alarmingly, this demographic also recorded the highest level of non-performing loans, amounting to IDR 763. 65 billion, and more than 60% of Gen Z borrowers reportedly used credit for lifestyle-related consumption rather than emergency needs (OJK, 2. Empirical evidence confirms that financial literacy among Indonesian university students remains relatively low. Rahman et al. found that students correctly answered only 45. 39% of key financial knowledge questions. This paradox raises an important question: why do young adults who have access to financial products and information continue to make suboptimal financial decisions? One theoretical framework that helps explain this phenomenon is the theory of planned behavior (Ajzen, 1. , which posits that behavior is shaped not only by individual attitudes and knowledge, but also by subjective norms and perceived behavioral controlAimany of which are developed within the family environment. The family serves as a primary agent of financial socialization, shaping individualsAo financial attitudes, values, and behaviors from an early age. Informal financial education practices, such as allowance management, family budget discussions, and parental involvement in household financial decisions, have been shown to enhance financial capability in adulthood. Rufaidah and Setiyono . demonstrate that family-based financial education strengthens financial self-efficacy, which subsequently supports better financial management behavior. Similarly. Rahardi et al. report that parental financial socialization is positively associated with studentsAo financial literacy Beyond its direct influence, the family may also function as a contextual factor that conditions the effectiveness of financial literacy in shaping financial decision-making. Individuals with comparable levels of financial knowledge may arrive at different financial decisions depending on the quality of family communication, authority structures, and decision-making dynamics within the household. Abriyanto and Barusman . emphasize that family socioeconomic conditions and parenting styles significantly affect studentsAo ability to apply financial knowledge in real-world financial Previous studies provide important foundations but leave several gaps. Dewi et al. conceptualize financial literacy as a multidimensional construct comprising Agustin & Numberi Global Advances in Business Studies 2026, 5. , 18-30 E-ISSN: 2828-8394 org/10. 55584/Gabs. financial awareness, experience, knowledge, and skills, and provide empirical evidence from the Indonesian context. However, their study primarily focuses on the relationships among financial literacy components and does not extend the analysis to financial decision-making as a behavioral outcome. Moreover, the model adopts an individual-centered perspective and does not account for the role of family context in translating financial capability into actual financial decisions. Other studies examining the relationship between financial literacy and financial behavior tend to treat financial literacy as a direct and linear predictor of individual decision-making (Rahadi, et al. , 2. While such findings confirm the importance of financial literacy, they overlook potential contextual factors that may strengthen or weaken this relationship. In particular, the moderating role of family decision-making in influencing the effectiveness of financial literacy remains underexplored. Similarly. Rufaidah and Setiyono . acknowledge the importance of family-related factors but treat them primarily as background characteristics rather than as analytical mechanisms that interact with individual financial literacy. Taken together, existing studies have not sufficiently explained whether financial literacy consistently leads to sound financial decisions among youth, or whether this relationship depends on family decision-making dynamics. Moreover, empirical evidence focusing on young adults in underrepresented regions such as Papua remains Addressing these gaps, the present study introduces family decision-making as a moderating variable within a multidimensional financial capability framework and focuses on university students in Jayapura. This study aims to examine the moderating role of family decision-making in the relationship between financial literacyAiparticularly financial knowledge as its core componentAiand financial decision-making among university students. Importantly, this study highlights that financial knowledge emerges as the most influential dimension of financial capability, while family decision-making plays a critical moderating role in shaping youth financial decisions. The findings are expected to contribute to the financial capability literature by providing a more contextualized understanding of youth financial behavior and to inform the design of more effective financial education programs that integrate both individual competencies and family-based financial Literature review and hypotheses developlement Financial capability and financial decision-making Financial capability has been widely conceptualized as a multidimensional construct that reflects an individualAos ability to manage financial resources effectively. Prior studies emphasize that financial capability extends beyond financial knowledge alone and includes awareness, experience, and skills that jointly influence financial behavior and decision-making (Hung. Parker, & Yoong, 2009. Atkinson & Messy, 2. In the Indonesian context. Dewi et al. provide empirical evidence that financial literacy comprises several interrelated dimensions, including financial awareness, experience, knowledge, and skills, which together shape individualsAo financial competence. Financial awareness reflects individualsAo attentiveness to financial planning and information-seeking behavior, which serves as a foundation for developing financial knowledge. Individuals who actively seek financial information and engage in planning activities tend to possess a better understanding of financial concepts and products. Empirical studies consistently report a positive relationship between financial awareness and financial knowledge, suggesting that awareness plays a critical role in enhancing financial literacy. Financial experience represents individualsAo exposure to real-life financial activities, such Agustin & Numberi Global Advances in Business Studies 2026, 5. , 18-30 E-ISSN: 2828-8394 org/10. 55584/Gabs. as managing income, savings, debt, or investment decisions. Experiential learning allows individuals to translate abstract financial concepts into practical understanding, thereby strengthening financial skills. Previous studies indicate that individuals with greater financial experience tend to demonstrate stronger financial skills, particularly in budgeting, monitoring expenses, and evaluating financial alternatives. Financial knowledge and financial skills are often regarded as key drivers of financial decision-making. Financial knowledge equips individuals with the cognitive ability to evaluate risks, returns, and long-term consequences, while financial skills reflect the technical capacity to implement financial plans. Empirical evidence generally supports the positive influence of financial knowledge on sound financial decisions. however, findings related to financial skills remain mixed, suggesting that skills alone may not consistently translate into rational financial behavior without supportive contextual factors. Based on this literature, the following hypotheses are proposed. H1: Financial awareness positively influences financial knowledge H2: Financial experience positively influences financial skill H3: Financial knowledge positively influences financial decision H4: Financial skill positively influences financial decision Family decision-making as a contextual factor The family plays a central role in shaping individualsAo financial attitudes, values, and behaviors through financial socialization processes. Family Financial Socialization Theory (Gudmunson & Danes, 2. posits that financial behaviors are formed through interactions within the family, including parental guidance, communication patterns, and shared decisionmaking practices. Through these mechanisms, families influence not only what individuals know about finance but also how they apply this knowledge in real-life decisions. Empirical studies demonstrate that family-based financial education enhances financial selfefficacy and financial literacy among young adults (Rufaidah & Setiyono, 2023. Rahadi, et al. Open communication, participatory decision-making, and supportive parental involvement have been associated with better financial outcomes. Conversely, highly centralized or dominant family decision structures may limit individual autonomy in financial decisionmaking, particularly among youth. Despite this evidence, most existing studies position family-related variables as direct predictors or background characteristics rather than as contextual mechanisms. As a result, the interaction between individual financial capability and family decision-making dynamics remains insufficiently explored. This limitation is particularly relevant for young adults, who often operate within family financial systems while simultaneously developing independent financial identities Research gap and moderating role of family decision-making Although prior studies have established the importance of financial literacy and financial capability in shaping financial behavior, several gaps remain. First, research by Dewi et al. focuses on relationships among financial literacy components but does not extend the analysis to financial decision-making as a behavioral outcome, nor does it incorporate family context into the model. Second, studies examining the relationship between financial literacy and financial behavior often treat this relationship as direct and linear (Rahadi et al. , 2. overlooking the possibility that the effectiveness of financial literacy may depend on contextual Third, while family-related factors have been acknowledged in studies of youth financial behavior (Rufaidah & Setiyono, 2. , they are typically treated as background variables rather than as analytical mechanisms that interact with individual financial capability. These limitations suggest that financial literacy may not uniformly translate into sound Agustin & Numberi Global Advances in Business Studies 2026, 5. , 18-30 E-ISSN: 2828-8394 org/10. 55584/Gabs. financial decisions across different family environments. Individuals with similar levels of financial knowledge and skills may arrive at different financial decisions depending on family communication patterns, authority structures, and decision-making involvement. This gap is particularly salient in collectivist cultural settings, where family influence remains strong during emerging adulthood. Addressing these gaps, the present study introduces family decision-making as a moderating variable in the relationship between financial capability components and financial decisionmaking among university students. By focusing on youth in Jayapura. PapuaAian underrepresented region in financial behavior researchAithis study provides new empirical insights into how family decision-making dynamics condition the effectiveness of financial Accordingly, the following hypotheses are proposed: H5: Family decision-making moderates the relationship between financial knowledge and financial decision H6: Family decision-making moderates the relationship, between financial skill and financial decision Figure 1. Research paradigm: financial literacy Research methods Sample and data collection This study involved 229 youth participants residing in Jayapura. Papua. Indonesia. Following Hair et al. , the recommended minimum sample size for structural equation modelling (SEM) is between 5 and 10 times the number of indicators. With 30 indicators included in the measurement model, a sample size ranging from 150 to 200 respondents is considered adequate. Therefore, the collected sample of 229 participants meets the minimum requirement for PLS-SEM analysis. Data were gathered using structured questionnaires distributed through both faceto-face interviews and self-administered online surveys. Purposive sampling was employed to ensure that respondents met the following criteria: aged between 17 and 25 years, and residing in urban areas of Jayapura. Measures The measurement instruments were adapted from Dewi et al. and designed to capture the following laten constructs: A Financial awareness (FA) A Financial experience (FX) A Financial skill (FS) Agustin & Numberi Global Advances in Business Studies 2026, 5. , 18-30 E-ISSN: 2828-8394 org/10. 55584/Gabs.

Data analysis The data were analyzed using partial least squares structural equation modeling (PLS-SEM) with SmartPLS 4 software. A two-step approach was employed, comprising the evaluation of the measurement model followed by the structural model.

Before assessing the structural relationships, the measurement model was evaluated to ensure indicator reliability and construct validity. Although the initial instrument consisted of 30 indicators . ive items per construc. , six indicators were excluded during the measurement model evaluation due to outer loadings below the recommended threshold of 0. Following Hair et al. , indicators with insufficient loadings were removed to enhance construct reliability and convergent validity. The final measurement model retained 24 indicators, which adequately represent the conceptual domains of each construct. Structural model evaluation Once the measurement model was validated, the structural model was assessed using the following procedures: Variance inflation factor (VIF): Evaluated for multicollinearity among predictor VIF values below 5 indicate acceptable levels A Path coefficients: Estimated using a bootstrapping procedure with 5,000 The significance of each path was assessed through t-values, p-values and confidence intervals A Coefficient of determination (R. : Used to evaluate the explanatory power of endogenous constructs.

Results and discussion The evaluation of the measurement model aims to assess the reliability and validity of the latent constructs used in the study. As recommended by Hair et al. , four key indicators were examined: outer loadings, internal consistency reliability (CronbachAos alpha and composite reliabilit. , convergent validity . verage variance extracted or AVE), and discriminant validity (HTMT). Table 1 summarizes the results of the measurement model assessment, including the outer loadings (OL). CronbachAos alpha (CA), composite reliability (CR), and AVE for each construct. All outer loadings exceeded the threshold value of 0. 70, indicating strong indicator reliability. One item under financial decision (FD. had a slightly lower loading . , but it was retained due to the construct's overall acceptable CR and AVE values, which is considered acceptable in PLS-SEM analysis. Regarding internal consistency reliability, all constructs achieved CronbachAos alpha values above 0. 70, with the lowest value found in financial decision . and the highest in financial skill . Composite reliability (CR) values ranged from 0. 891, surpassing the recommended minimum of 0. 70 and confirming the internal consistency of each construct. Convergent validity was also satisfied, as all constructs recorded AVE values greater than 0. The AVE scores ranged from 0. inancial decisio. inancial skil. , indicating that each construct was able to explain more than 50% of the variance in its indicators. Table 1. Outer loading (OL). CronbachAos alpha (CA), composite reliability (CR), and AVE for each measurement variable Data processing result using SmartPLS 4 This study used the Heterotrait-Monotrait ratio of correlations (HTMT) as recommended by Henseler et al. HTMT values below 0. 90 indicate that each latent construct is empirically distinct from the others.

Heterotrait-Monotrait ratio (HTMT) Data processing result using SmartPLS 4 As shown in Table 2, all HTMT values among the main constructs and interaction terms are below the recommended threshold. The highest HTMT value . was observed between financial knowledge (FK) and financial decision (FD), which remains within the acceptable range. Interaction terms (FDM y FS and FDM y FK) demonstrated low HTMT values with all main constructs, confirming that the moderating variables are distinct and do not overlap with the predictor constructs. These findings collectively confirm that the latent variables used in this study are both valid and reliable, allowing for further analysis of the structural model. Following the confirmation of the measurement model's validity and reliability, the next stage involved assessing the structural . The evaluation covered collinearity testing, hypothesis testing through path coefficients, effect size . A), and the explanatory power of the model as reflected in RA values. Variance inflation factor (VIF) values were examined to detect multicollinearity among predictor constructs. As shown in Table 3, all VIF values are below the conservative threshold of 5, indicating that collinearity is not a concern in this model (Hair. Hult. Ringle, & Sarstedt, 2. The highest VIF value was observed in the interaction term FDM y FK . , which remains well within the acceptable limit. Table 3.

This also falls under the moderate category. A The financial skill (FS) variable obtained an RA of 0. 481 and an adjusted RA of 0. which means that 48. 1% of its variance is explained by the predictors. This is interpreted as weak to moderate explanatory power. These values demonstrate that the model explains a substantial proportion of variance in financial-related outcomes among youth respondents. Predictive relevance was assessed using the QApredict values obtained through the blindfolding procedure. As shown in Table 6, all endogenous constructs demonstrated QA values greater than zero, indicating that the model has satisfactory predictive capability Table 6. Predictive relevance (QA) QApredict Data processing result using SmartPLS 4 Specifically, financial knowledge (QA = 0. and financial skill (QA = 0. showed high levels of predictive relevance. Financial decision also exhibited a strong predictive relevance with QA = 0. 339, which falls within the substantial threshold. These results confirm that the exogenous variables in the model possess adequate predictive power for their respective endogenous outcomes. The findings of this study provide new insights into the dynamics between financial capability and financial decision-making among young adults, with particular attention to the moderating role of family decision-making (FDM). Consistent with the framework of financial literacy proposed by Dewi et al. , the results reveal that each component of financial capabilityAiawareness, experience, knowledge, and skillAiplays a distinct role in shaping financial behavior. Firstly, financial awareness was found to have a strong and significant influence on financial knowledge ( = 0. 727, p < 0. fA = 1. , confirming previous studies that emphasize the foundational role of awareness in promoting financial understanding (Lusardi & Mitchell, 2. Awareness indicators such as planning purchases and seeking financial information appeared to significantly enhance students' financial knowledge, including concepts such as risk-return trade-offs and financial institutions. This aligns with the premise of the theory of planned behavior (Ajzen, 1. , which Agustin & Numberi Global Advances in Business Studies 2026, 5. , 18-30 E-ISSN: 2828-8394 org/10. 55584/Gabs. suggests that increased awareness contributes to more favorable financial attitudes and perceived behavioral control. Secondly, financial knowledge significantly predicted financial decision-making ( = 0. 679, p < 0. fA = 0. , reinforcing the assertion that cognitively equipped individuals are more likely to engage in responsible financial behavior (Atkinson & Messy, 2. Students who understood core concepts in finance demonstrated stronger decision-making ability, such as avoiding impulsive purchases or planning with longterm consequences in mind. Third, the path from financial experience to financial skill ( = 0. 693, p < 0. = 0. was both statistically and practically significant. This indicates that exposure to real-life financial activitiesAisuch as managing savings, budgeting from scholarships or part-time income, and engaging with financial platformsAicontributes to the development of practical financial skills. This supports findings by Grohmann et al. , who assert that experiential learning plays a critical role in translating theoretical literacy into actionable competence. However, an unexpected result emerged regarding the influence of financial skill on financial decision-making. The relationship was found to be non-significant ( = 0. 041, p = 0. fA = 0. , suggesting that skill alone, without contextual reinforcement or support, may not directly influence financial choices among students. This result diverges from prior expectations and implies that skills such as budgeting or tracking debt may not be sufficient in guiding behavior unless mediated by other factorsAisuch as attitudes, emotional readiness, or external guidance. The role of family decision-making was observed to be both direct and interactive. FDM showed a modest but significant direct effect on financial decision-making ( = 133, p = 0. fA = 0. , implying that students who are involved in family discussions about money are more likely to exhibit thoughtful financial behavior. This finding supports the view that family interaction enhances financial self-efficacy (Rufaidah & Setiyono, 2. and reinforces social norms that shape long-term habits (Gudmunson & Danes, 2. Most notably, the interaction effect between FDM and financial knowledge was statistically significant ( = -0. 119, p = 0. fA = 0. , suggesting a moderating role of family in the translation of knowledge into decisions. Interestingly, the negative coefficient implies that in families with strong decision-making structures, the impact of individual knowledge may be dampenedAiperhaps due to reliance on parental input or deference to family authority. This interaction reflects the complex interplay between individual agency and familial norms, especially within collectivist cultures such as Papua. It also supports the assertion of Ayuninggar et al. that family context mediates the effectiveness of formal financial education. In contrast, the interaction between FDM and financial skill was not significant ( = 0. 049, p = 0. , suggesting that family influence may not enhance the utility of technical skills in decision-making. This may be due to the nature of financial skill being more mechanical or transactional, requiring less negotiation or shared values compared to financial knowledge. The overall model demonstrated satisfactory explanatory power, with RA values indicating moderate predictability for financial decision-making . , financial knowledge . , and financial skill . In addition, all QA values were positive and well above the threshold of 0, confirming the modelAos predictive relevance (Hair. Hult. Ringle, & Sarstedt, 2. Taken together, these results highlight the multifaceted nature of financial behavior Agustin & Numberi Global Advances in Business Studies 2026, 5. , 18-30 E-ISSN: 2828-8394 org/10. 55584/Gabs. among youth. While knowledge and experience are critical, their effectiveness depends on the socio-familial context in which financial decisions are made. This underscores the importance of incorporating family-based approaches into financial education programs, particularly in regions where family dynamics play a central role in shaping individual values and behaviors. Conclusions and suggestion This study explored the relationship between financial capabilityAicomprising financial awareness, experience, skills, and knowledgeAiand financial decision-making among youth in Jayapura. Papua. Indonesia, with a specific focus on the moderating role of family decision-making. Using a PLS-SEM approach on data collected from 229 participants, the findings reveal several important insights. First, financial awareness was found to significantly enhance financial knowledge, which in turn emerged as the strongest predictor of sound financial decision-making. Financial experience also played a vital role in developing financial skills. these skills did not directly translate into improved financial decisions. Notably, the moderating effect of family decision-making was significant only in the relationship between financial knowledge and financial decisions, suggesting that family dynamics can either strengthen or weaken the impact of financial literacy on behavior. These findings highlight the multifaceted nature of financial decision-making among young people and the importance of integrating sociocultural dimensionsAi particularly family influenceAiinto financial education strategies. For policy-makers, educators, and development practitioners, the results underscore the need for financial literacy programs that extend beyond the individual and involve family structures to foster more sustainable financial behaviors in youth. Future research could benefit from examining similar models across different cultural contexts, socioeconomic groups, or educational levels to further generalize and validate these findings.
