Table 1. Semantic domains, theme definitions, and inter-coder agreement [64].
| Semantic domains and theme definitions | Krippendorf’s cu-Alpha |
|---|---|
| Technology acceptance | 0.71 |
| Performance expectancy refers to perceived usefulness or helpfulness of smoking cessation mobile applications and their features in achieving desired health goals and behaviors. | |
| Effort expectancy refers to perceived ease of use or effortfulness with which one can navigate mobile applications and their features and seamlessly integrate them in one’s life. | |
| Facilitating conditions are factors that can aid or impede the uptake or use of mobile applications or their features. These include individual-related (e.g., skills, predispositions, prior experiences) and technical-related (e.g., infrastructure) factors. | |
| Hedonic motivation refers to perceived fun, pleasure, or enjoyment (or lack thereof) associated with the use of mobile applications and their features. | |
| Social influence refers to perceived importance of significant others’ recommendations and approval of using mobile applications and their features. | |
| Sentiment | 0.58 |
| Positive sentiment capture statements or remarks that indicate a sense of approval, praise, or certainty about any aspect of smoking cessation mobile applications and their features such as their worthiness, utility and impact, time and effort investment, and compatibility with one’s life. | |
| Neutral sentiment capture statements or remarks that (a) are neither positive or negative in tone, (b) contain an equal number of positive and negative remarks, or (c) are conditional (i.e., positive in nature but dependent on the presence or absence of another factor). | |
| Negative sentiment capture statements or remarks that indicate a sense of disapproval, criticism, or skepticism about any aspect of smoking cessation mobile applications and their features such as their worthiness, utility and impact, time and effort investment, and compatibility with one’s life. | |
| Interventional features | 0.88 |
| Self-monitoring: The ability to monitor and record smoking behavior, its antecedents, and consequences when attempting to quit smoking. | |
| Tailored feedback and support: The delivery of support that is unique to an individual based on user-input regarding smoking behavior, antecedents, progress toward goals, or pre-specified times and locations. | |
| Educational content: Information related to smoking and smoking cessation, including steps for quitting, quitting strategies, and benefits, among others. | |
| Design concepts: Statements related to user interface, content input and delivery, information structure, navigation, typography, and aesthetics of smoking cessation applications or their features. | - |
| Suggestions: Statements concerned with improvements, modifications, or additions to smoking cessation applications or their features aimed to improve their functionality and/or design. | - |
| Emerging themes * | - |
| Intent or willingness to use: Statements reflecting intentions or willingness to use smoking cessation applications or their features in the future. |
Multi-value coding of quotes was applied across semantic domain, but themes within a semantic domain were mutually exclusive.
*Themes not defined a priori and thus no inter-coder agreement was calculated for this exploratory part of the analysis.
