The Theory of Reasoned Action (Ajzen, 1985; Ajzen & Fishbein, 1977) emphasizes the crucial and immediate role of behavioral intentions to adopt a new behavior. The Theory of Planned Behavior (Ajzen, 1991) further suggests that the behavioral intention is shaped by attitudes (the beliefs about the positive or negative consequences of the behavior), subjective norms (the motivations and beliefs to comply with the behavior from other peers and social norms), and perceived behavior control (the beliefs of control over one’s behavior). The theory of planned behavior has been used to explain the adoption of health promotion behavior, such as PA (Hausenblas et al., 1997), smoking cessation (Topa & Moriano Leon, 2010), HIV prevention (Albarracín et al., 2001), and chronic illness treatment adherence (Rich et al., 2015).
Adherence in Ethnic Minorities : The Case of South Asians in Britain
Published in Lynn B. Myers, Kenny Midence, Adherence to Treatment in Medical Conditions, 2020
Adherence to medical advice can be considered as an example of health behaviour. Thus, the usual models which have been applied to the understanding of health behaviour can be applied to adherence – viz. the health belief model (HBM, Rosenstock, 1966, Becker, 1974) and the theory of reasoned action (TRA, Fishbein and Ajzen, 1975), with its revision in the form of the theory of planned behaviour (TPB, Ajzen, 1988). This chapter will not attempt to review these models in full but, citing examples from the area of preventive health, will use a selection of the models’ key theoretical concepts to further understanding of the relationship between ethnicity and adherence. For a description of the models, see Home and Weinman, Chapter 2.
Development of Diabetes Self Care Assessment Tool (D-SCAT): Conceptualization and Assessment of Self-Care in a Real Life Setting

Theory of Planned Behavior (TBP) was established by Icek Ajzen which included perceived behavior control on theory of reasoned action proposed by Martin Fishbein and Icek Ajzen (1980). Perceived behavior control was originated from Self-Efficacy Theory (SET) proposed by Bandura (1977) and came from his Social Cognitive Theory (SCT). According to Bandura, individual’s expectations such as motivation, performance and frustration feelings due to repeated failures determine behavior reactions of a person. Expectation has two types; self-efficacy and outcome expectancy. Self-efficacy was defined as the conviction that a person can successfully execute the required behavior to produce the outcomes. Meanwhile, the outcome expectancy refers to a person’s estimation that a given behavior will lead to certain outcome. Bandura further stated that self-efficacy is the most important precondition for behavioral change, since it determines the initiation of coping behavior. However, regardless of the theory used, majority of research conducted to date focusing more on a single, individual behavior. Whilst in reality, patients are routinely instructed to make multiple lifestyles behavior change simultaneously in order to attain successful outcomes.
The impact of social influence on perceived usefulness and behavioral intentions in the usage of non-pharmaceutical interventions (NPIs)

TAM was first developed by Fred Davis [8,13], utilizing the theory of reasoned action to guide development of many key constructs [10]. After this, Davis enhanced the model and it advanced into the leading model for forecasting the acceptance of technology [8]. TAM introduced the constructs of perceived usefulness, perceived ease of use as precursors of behavioral intentions – thereby leading to actual usage [9]. The theory of reasoned action suggests that an individual with behavioral intentions would result in the action of that specific behavior [10]. Later competing technology acceptance models were consolidated into the Unified Theory of Acceptance and Use of Technology (UTAUT) model [14]. The basic concepts (individual reactions, intentions, and actual use) of the UTAUT model are the same as in the TAM model. However, the UTAUT model also included the construct of facilitating conditions, which are defined as ‘the degree to which an individual believes that an organizational and technical infrastructure exist to support the use of the system’ [14] with an aim to eliminate the obstacles to the use of the technology. Interestingly, however, the research paper by Venkatesh et al. [14] hypothesized the construct of facilitating conditions not to have a significant impact on behavioral intentions, which in fact turned out to be the case in their research paper. It is also to be noted that the research setting in the Venkatesh et al. study was a training program associated with the new technology introduction within an established and immediate organizational setting.
Influencing factors of Chinese special education teacher turnover intention: understanding the roles of subject well-being, social support, and work engagement

Special education teachers have a relatively higher rate to leave the field than general education teachers. The shortage of special education teachers has been an expressed concern for researchers and policymakers for decades. The overall problem seen in the field of special education is that the high attrition rates of highly qualified special education staff, leading to inadequate services for those students with special needs (Gregory 2015, Feng and Sass 2017). Previous research found that students with special needs continued decreasing education outcomes if special education teachers were not retained in the field (Smith et al.2010). When highly qualified special education teachers have remained in the field, students who received special education services would experience more success and show greater academic achievement (Nickson and Hughes 2010). Research in this domain potentially values the turnover intention because it could be used to predict teachers’ turnover (Hom et al.1992). Based on the initial Theory of Reasoned Action, an intention to engage in a certain behavior is often considered as one of the best predictors of whether a person will engage in that behavior (LaCaille 2013).
Acceptability and preferences for long-acting antiretroviral formulations among people with HIV infection

Our study is limited to a single center, so our results may not generalize to the general population. Although we explored some hypothetical scenarios, these medications are still investigational and the lack of accurate information on some factors such as the frequency of administration, dosing, cost difference, and location of administration might alter the willingness and choice of ART when these medications become available. Another limitation, inherent to survey questionnaires, is the reliability and validity of the questions. While we used validated scales when possible, there are no validated scales to assess the likelihood of use and preference of LA ART. We tried to overcome this limitation by using questions adapted from similar contexts (e.g., pills vs. LA injectable contraception in women’s health) (Curtis et al., 2016) and by conducting cognitive interviews to ensure the clarity of the questions. Willingness to use LA ART might not predict actual future behavior, since the hypothetical “likelihood of use” and actual use of the new delivery system are presumably very different. However, the theory of reasoned action asserts that the most important determinant of the behavior is behavioral intention (Doswell et al., 2011).
