The Mediating Role of Risk, Credibility, and Convenience in the Relationship between Initial Trust and Purchase Intention in Online Shopping

The concept of e-commerce, or online shopping, has witnessed significant growth in recent years, driven by factors such as convenience and cost-effectiveness. However, concerns related to initial trust, perceived risks, credibility of online platforms, and convenience have hindered some consumers from making purchases online. This study aims to investigate the relationship be-tween initial trust and purchase intention among online shoppers, with a focus on the mediating factors of risk, credibility, and convenience. The research will be conducted in the Klang Valley region of Malaysia, targeting trainees who are active online shoppers. Data will be collected through a structured questionnaire, and statistical methods such as regression analysis and mediation analysis will be employed for data analysis. The study aims to provide valuable insights into the factors that shape initial trust and their impact on purchase intention, contributing to the existing body of knowledge in the field of e-commerce. The findings of this research will have practical implications for online retailers, enabling them to develop strategies to enhance trust, reduce perceived risk, establish credibility, and improve convenience, ultimately driving purchase intention among online shoppers.


Introduction
The growth of e-commerce, or online shopping, has revolutionized the way people purchase goods and services, allowing them to buy directly from sellers How to cite this paper: Kathiarayan, V. (2023). The Mediating Role of Risk, Credibility, and Convenience in the Relationship between Initial Trust and Purchase Intention in Online Shopping. Technology and Investment,14,[160][161][162][163][164][165][166][167][168][169][170] https://doi.org/10. 4236/ti.2023.143010 on the Internet without intermediaries (Li & Zhang, 2002). Convenience has been a significant driver of the shift to online shopping, with consumers valuing the ability to shop anytime and enjoy convenient services like curbside pickup and same-day delivery (Lazaris, 2021). The share of total retail sales from online sales has been steadily increasing, reaching over 10% and bringing in billions of dollars in adjusted sales (U.S. Department of Commerce, 2019). The  pandemic further accelerated the adoption of online shopping, with a significant increase in online shopping activities reported among consumers in several countries (McKinsey & Company, 2020;Marek, 2021).
Despite the growth in online shopping, concerns about risks, credibility, and convenience have hindered some consumers from making online purchases (Liu & Liang, 2011). Issues such as privacy breaches, online fraud, product quality disparities, and delayed deliveries contribute to a lack of trust in online shopping (Garcia, 2015;Davis, 2016). To address these concerns, online retailers have implemented secure payment systems, encryption technologies, transparent return policies, and prompt customer service (Smith et al., 2019;Jones, 2017).
However, there is a need for comprehensive investigation into how initial trust influences consumers' purchase intention, and the mediating effects of risk, credibility, and convenience in this relationship (Suh & Han, 2003;Al-Debei et al., 2015). Previous research in the Malaysian context has provided limited attention to these factors (Alfhian, Azizi, & Yee, 2009;Leen, Ramayah, & Omar, 2010;Hashim, Ghani, & Said, 2009). This study aims to fill this research gap and gain a deeper understanding of the interplay between initial trust, risk, credibility, convenience, and purchase intention among online shoppers in Malaysia.
The research objectives are to assess the sequential mediated relationships between initial trust and purchase intention through risk, risk and credibility, risk and convenience, credibility and convenience, and risk, credibility, and convenience. Additionally, the direct effect of initial trust on purchase intention will be examined. The research questions focus on understanding the relationships between initial trust, risk, credibility, convenience, and purchase intention among online shoppers in Malaysia.

Framework of Hypotheses
The research hypotheses are as follows: 1) there is a significant indirect effect of Initial Trust on Purchase Intention through Risk, 2) there is a significant indirect effect of Initial Trust on Purchase Intention through the sequential mediation of Risk and Credibility, 3) there is a significant indirect effect of Initial Trust on Purchase Intention through the sequential mediation of Risk and Convenience, 4) there is a significant indirect effect of Initial Trust on Purchase Intention through the sequential mediation of Credibility and Convenience, 5) there is a significant indirect effect of Initial Trust on Purchase Intention through the sequential mediation of Risk, Credibility, and Convenience, and 6) there is a sig-

The Role of Risk as a Mediator
Hypothesis One: A substantial indirect relationship exists between initial trust and purchase intention, mediated by the consumers' perception of risk. The tenet is grounded in the notion that a trusting environment can potentially allay perceived risks, paving the way for purchase considerations.

Sequential Mediation by Risk & Credibility
Hypothesis Two: Initial trust, in its capacity, shapes purchase intention through a combined mediating effect of risk and credibility. It posits that trust can serve a dual purpose: dampening risk perceptions and augmenting vendor credibility, thereby influencing buying considerations.

Interplay of Risk & Convenience as Mediators
Hypothesis Three: Initial trust carves its influence on purchase intention through the dual mediation of risk and convenience. It suggests that platforms enjoying higher trust may be deemed more convenient, and in conjunction with reduced risk perceptions, may bolster purchase intent.

Credibility & Convenience in Tandem Mediation
Hypothesis Four: Initial trust's sway over purchase intention is molded through the dual mediation of credibility and convenience. Trusted platforms, by virtue of their stature, might be viewed as both credible and user-friendly, thus amplifying purchasing tendencies.

Triple Mediation by Risk, Credibility & Convenience
Hypothesis Five: Initial trust operates a domino effect on purchase intention, mediated sequentially by risk, credibility, and convenience. This hypothesis elucidates the multifaceted pathways through which trust impacts buying behaviors.

Direct Influence on Purchase Intention
Hypothesis Six: Independent of the mediators, initial trust wields a pronounced direct influence on purchase intention, underscoring trust's unmediated potency in guiding consumer choices.

Towards a Comprehensive Understanding
The set of hypotheses, though firmly anchored in Hayes' conceptual underpinnings, offers a more detailed exposition of how trust interfaces with other pivotal constructs in the e-commerce sphere. By weaving this intricate tapestry, the study endeavors to provide a richer academic narrative, aiding scholars and practitioners in the domain of online commerce.

Research Design
This study employs a quantitative research design to examine the relationship between initial trust and purchase intention, as well as the mediating factors of risk, credibility, and convenience in the context of online shopping. A cross-sectional survey approach will be utilized to collect data from Perkeso Penjana EIS Trainees who engage in online shopping in Malaysia.

Sampling Technique
A combination of probability sampling and non-probability sampling techniques will be used to select the participants. The target population includes Perkeso Penjana EIS Trainees who engage in online shopping. A nested sampling approach will be employed, where sample members selected for each stage of the study will serve as a sampling frame for subsequent stages. The sample size will be determined to ensure adequate representation and minimize potential biases. The research combined both probability and non-probability sampling techniques, using nested sampling as described by Collins, Onwuegbuzie, and Jiao (2007). The sample size was set at 500 respondents out of a target population of 23,206 web shoppers in Malaysia. Power analysis, as recommended by Bruin (2006) and detailed by Faul, Erdfelder, Buchner, and Lang (2009), was employed to finalize the sample size considering parameters such as desired power, alpha significance level, effect size, and the main predictor variable.
Convenience and snowball sampling strategies were employed to gather the sample. The study took into account alpha value, power, and effect size, as highlighted by Cohen (1977), when determining the minimum sample size for hypothesis testing. The alpha value was set at 0.05 and power at 0.95. Participants should have a minimum of one year of full-time employment and be currently employed within Malaysia. The Krejcie and Morgan's (1970) sample size table   was referenced, suggesting a sample size of 500 for populations exceeding one million convenience sampling strategy was used, leading to 520 responses, of which only 500 were considered suitable for analysis.

Probability and Non-Probability Sampling Techniques in the Study
For the current study, the principle of Krejcie and Morgan's (1970) sample size table was adopted. This table is highly respected in the realm of research for its ability to provide guidance on appropriate sample sizes based on a given population. Given that our study focused on a population exceeding one million individuals, the table recommended a sample size of 500 participants to achieve a representative sample.

Non-Probability Sampling
In non-probability sampling, not all members of the population have a known or Data will be collected through an online survey administered to the selected participants. The survey will include validated measurement scales to assess the variables of interest, including initial trust, risk perception, credibility perception, convenience perception, and purchase intention. The survey will be pretested to ensure clarity and validity of the questionnaire items.

Measurement Instruments
To measure the constructs of initial trust, risk, credibility, convenience, and purchase intention, established measurement scales will be utilized. These scales have been validated in previous research and have demonstrated satisfactory reliability and validity. Examples of measurement scales include the Trust Scale (Mcknight et al., 2002), the Perceived Risk Scale (Bauer et al., 2005), the Credibility Scale (Flanagin et al., 2008), the Convenience Scale (Kolsaker & Lee-Kelley, 2008), and the Purchase Intention Scale (Dodds et al., 1991). The scales will be adapted and modified as necessary to align with the specific context of online shopping among Perkeso Penjana EIS Trainees.

Data Analysis
The collected data will be analyzed using the Hayes Process Macro Model 6 for SPSS. This macro enables the examination of multiple mediators in a serial mediation model. The mediation analysis will involve calculating various indirect effects, including the indirect effect of initial trust on purchase intention through specific mediators (e.g., risk, credibility, convenience). The direct effect of initial trust on purchase intention will also be assessed. Descriptive statistics, validity and reliability analyses, and hypothesis testing will be conducted to interpret the findings and evaluate the research hypotheses.

Results
The mediation analysis conducted using the PROCESS SPSS macro (Hayes, 2013)  The analysis revealed a positive correlation between initial trust and risk, indicating that as initial trust increases, so does the perception of risk. This, in turn, influences a higher purchase intention. Similarly, higher levels of initial trust were found to contribute to a greater perception of credibility, which positively influences purchase intention. Additionally, initial trust played a role in perceiving convenience, subsequently influencing purchase intention positively.
The mediation analysis confirmed the presence of significant indirect effects of initial trust on purchase intention through the mediating factors. Specifically, the indirect effect analysis revealed a statistically significant indirect effect of initial trust on purchase intention through risk. This suggests that participants who differed by one unit in their reported initial trust were estimated to differ by. 14 units in initial trust due to risk, subsequently leading to higher purchase intention. The findings also supported the indirect effects of initial trust on purchase intention through the sequential mediation of risk and credibility, as well as through the sequential mediation of credibility and convenience.
These results contribute to the understanding of the relationship between initial trust and purchase intention in the context of online shopping. They emphasize the importance of managing risk, credibility, and convenience as me-

Conclusion
The discussion in this study aimed to investigate the relationship between initial trust and purchase intention, mediated by factors such as risk, credibility, and convenience in the context of online shopping. The results of the analysis shed light on the complex relationships between these variables and offer valuable in- The analysis revealed a significant relationship between initial trust and purchase intention, mediated by risk. Higher levels of initial trust were associated with lower perceived risk, leading to increased purchase intention. This finding aligns with previous research that emphasizes the importance of trust in mitigating perceived risks in online transactions.
Moreover, the study found a significant relationship between initial trust and purchase intention mediated by both risk and credibility. Initial trust positively influenced perceived credibility, which in turn positively influenced purchase intention. This finding is consistent with previous studies highlighting the role of credibility and reputation in building trust and encouraging purchase behavior. Additionally, the analysis revealed a significant relationship between initial trust and purchase intention mediated by risk and convenience. Higher levels of initial trust were associated with increased perceived convenience, leading to higher purchase intention. This result aligns with studies emphasizing the influence of convenience on consumers' purchase intentions in the online context. Furthermore, the study indicated a significant relationship between initial trust and purchase intention mediated by credibility and convenience. Initial trust positively influenced perceived credibility and convenience, both of which positively influenced purchase intention. Previous research has also highlighted the role of credibility and convenience in shaping consumers' trust and purchase intentions.
The research findings provide evidence of a significant relationship between initial trust and purchase intention mediated by the combined effects of risk, credibility, and convenience. Higher levels of initial trust were associated with reduced perceived risk, increased credibility, and enhanced convenience, all contributing to higher purchase intention. Finally, the analysis confirmed a significant direct relationship between initial trust and purchase intention. Higher levels of initial trust directly led to increased purchase intention, independent of the mediating factors. Overall, the findings highlight the significance of trust and its mediating factors in shaping consumers' purchase intention in online shopping. Building trust by mitigating perceived risks, establishing credibility, and enhancing convenience can positively influence consumers' purchase behavior.
Future research can further explore additional factors contributing to initial trust and purchase intentions, as well as investigate trust dynamics throughout the customer journey in the online marketplace.
