# User Acceptance of Smart Watch for Medical Purposes: An Empirical Study
## 5 Findings and Discussion
### Hypotheses Testing Using PLS-SEM  
After the assessment of the measurement model, the next in line is the structural model [78; 79; 80]. This involves the evaluation of coefficient of determination (R\({}^{2}\)), path coefficients through bootstrapping which is the long process involving 5000 re-samples [81; 86; 91; 92; 93]. Table 8 provides the path coefficients, \(t\)-values, and \(p\)-values for all hypotheses concerning \begin{table}

Table 7: Heterotrait-Monotrait Ratio (HTMT). the path analysis. All of the researchers have supported every hypothesis. Interpretation of data shows that the hypotheses (H1, H2, H3, H4, H5, H6, and H7) have been supported by empirical data. The testing of the structural model is usually done based on the measurement of coefficient of determination (\(R^{2}\) value) [71]. The coefficient is expressed as the squared correlation between actual and predicted values of the particular endogenous construct, and the main aim of this coefficient is to measure the predictive accuracy of the model [94; 95]. The coefficient indicates the cumulative influence of the exogenous latent variables over an endogenous latent variable. As the coefficient is the squared correlation between the actual values of the variables and the predicted values of variables, it introduces further the sense of variance degree in the endogenous constructs. The value is considered to be high if it exceeds 0.67, which indicates that the values ranging from 0.33 to 0.67 are direct ones and the value between 0.19 to 0.33 are considered weak values. The value is termed inadmissible if it is smaller than 0.19 according to [96]. As seen in Table 9 and Figure 2, it is clear that the model had high predictive power, supporting very nearly 75.6%, 77.3%, and 82.8% of the variance in the adoption of SW, perceived usefulness and perceived ease of use, respectively. Sufficiency (SUF), Timeliness (TIM), Relevance (REL) and Personal Innovativeness (PER) have significant effects on Perceived Usefulness (PU) (\(\beta\) = 0.515, \(p\) < 0.01), (\(\beta\) = 0.382, \(p\) < 0.001), (\(\beta\) = 0.478, \(p\) < 0.001), and (\(\beta\) = 0.281, \(p\) < 0.05) respectively; hence H1, H2, H3, and H4 are supported. The relationship between Personal Innovativeness (PER) and Perceived Ease of Use (PEOU) (\(\beta\) = 0.329, \(p\) < 0.001) is statistically significant, so hypothesis H5 is generally supported. Perceived Usefulness (PU) and Perceived Ease of Use (PEOU) have significant effects on Adoption of Smart Watch (ASW) (\(\beta\) = 0.668, \(p\) < 0.01), and (\(\beta\) = 0.420, \(p\) < 0.05), respectively; therefore, H6 and H7 are supported.
