Summary
Everyday discrimination reduces smoking cessation success by lowering self-efficacy. This study highlights the need for interventions to address discrimination
Area of Science:
- Public Health
- Psychology
- Tobacco Research
Background:
- Discrimination's link to current smoking is established, but its impact on smoking cessation is understudied.
- Everyday discrimination's influence on smoking cessation requires further investigation.
- Self-efficacy is explored as a potential mediator between discrimination and smoking cessation.
Purpose of the Study:
- To evaluate the influence of everyday discrimination on smoking cessation.
- To examine self-efficacy as a mediator in the relationship between discrimination and smoking cessation.
Main Methods:
- 146 participants recruited from a Texas safety-net hospital (2011-2013).
- Perceived discrimination measured pre-quit attempt; self-efficacy assessed post-quit date.
- Biochemically-verified smoking abstinence assessed weekly for four weeks.
- Structural equation modeling used to analyze indirect effects.
Main Results:
- Significant indirect effect of discrimination on smoking cessation via self-efficacy at Weeks 1 and 4.
- Higher discrimination frequency correlated with lower self-efficacy post-quit.
- Lower self-efficacy increased likelihood of smoking at Weeks 1 and 4.
Conclusions:
- Perceptions of discrimination decrease smoking cessation likelihood by reducing self-efficacy.
- Intervention strategies are needed to mitigate discrimination's negative impact on cessation.
- Addressing discrimination and enhancing self-efficacy are crucial for smoking cessation interventions.

95.4K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

01:22Indirect Motor Pathways
3.6K
The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...

Self-efficacy is the belief in one's capacity to organize and execute actions necessary to manage prospective situations. This belief significantly influences how individuals approach goals, tasks, and challenges across different domains of life.Psychological and Educational ImpactsIndividuals with strong self-efficacy are more resilient in the face of difficulties. They are more likely to adopt effective problem-solving strategies, persist through obstacles, and regulate emotions such as...

01:24Generalization, Discrimination, and Extinction
1.4K
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

01:23EDTA: Indirect and Alkalimetric Titration
1.8K
Unlike direct titration, back-titration, and displacement titration, indirect titration is an EDTA titration method for quantifying anions. In the indirect titration method, anions are precipitated as their insoluble salts with excess metal ions. The filtrate containing the excess metal ions is directly titrated with standard EDTA until the endpoint is achieved. Another approach involves extracting the metal ion and back-titrating with standard EDTA to obtain the endpoint. In this way, the...

01:22Bioavailability: Influencing Factors
365
Bioavailability refers to the extent and rate at which a drug reaches systemic circulation in its active form. Extent refers to the amount of the drug that makes it into circulation, while rate is the speed at which it enters circulation. It is influenced by several factors critical for optimizing drug formulations, dosing regimens, and therapeutic outcomes.Physicochemical properties of drugs and formulationsThe solubility, stability, and dissolution rate of a drug significantly impact its...
