Depression: Moderation Effects of Depression Degree, using a wearable device named “Flow” aimed at treating depression with a technique called tDCS (transcranial direct current stimulation) developed by a Swedish company. In recent years, attention has been called to the drastically increased number of depression patients. In the context of flawed conventional treatment, this study creates a TAM (technology acceptance model) based model for depression treatment wearables, combining the features of the product and users. The independent variables include innovation, social influence, mobility, perceived cost and result demonstrability; the dependent variables include perceived usefulness, perceived ease of use, attitude and behavioral intentions; the moderating variable is depression degree. This study analyzes the degree of influence by independent variables and the effects of the moderating variable using SmartPLS 3.0 based on 386 conducted surveys. It is found out that innovation, social influence, mobility, perceived cost, result demonstrability, and perceived ease of use directly affect perceived usefulness; innovation and mobility affect perceived ease of use; social influence and perceived cost do not affect perceived ease of use. For a clearer and more systematic view of how independent variables affect dependent variables, 2nd Order CFA(Second Order Confirmatory Factor Analysis) method is utilized to prove the influence of external factor on perceived usefulness and perceived ease of use. It is also proved that perceived usefulness and perceived ease of use directly affect attitude, and attitude directly affects perceived usability. In the moderation study of depression degree, it is concluded that depression degree moderates 1) how social influence affects perceived usefulness, 2) how perceived ease of use affects perceived usefulness, and 3) how attitude affects behavioral intentions. Other assumptions of moderation effects are not proved. In a nutshell, this study sheds some light on the application and acceptability of new wearable products, and the popularization of depression treatment knowledge.
