Models of Birth Doula Access in Hospital Settings
Introduction: Continuous doula support during labor and delivery in the hospital setting is associated with improved maternal and newborn outcomes, such as reduced labor duration and higher infant Apgar scores. ACURE4Moms, a 4-arm cluster randomized controlled trial of 39 prenatal clinic groups across North Carolina, is evaluating whether community-based doula support can reduce low birthweight. This short report outlines hospital doula policy in…
A Cost Analysis of Rethink the Strip
BACKGROUND: Routine self-monitoring of blood glucose is a low-value practice that provides limited benefit for patients with non-insulin-treated type 2 diabetes mellitus. OBJECTIVES: We estimated the costs of Rethink the Strip (RTS), a multistrategy approach to the de-implementation of self-monitoring of blood glucose in primary care. RESEARCH DESIGN: RTS was conducted among 20 primary care clinics in North Carolina. We estimated the non-site-bas…
Perceived effectiveness of objective elements of vaping prevention messages among adolescents
Promising vaping prevention messages focus on the adverse consequences of vaping, use negative imagery and avoid speaking for teens using their vernacular or perspective
Development and Validation of the Trust in My Doctor, Trust in Doctors in General, and Trust in the Health Care Team Scales
Using Social Networks to Supplement RDD Telephone Surveys to Oversample Hard-to-Reach Populations
Random digit dialing (RDD) telephone sampling, although experiencing declining response rates, remains one of the most accurate and cost-effective data collection methods for generating national population-based estimates. Such methods, however, are inefficient when sampling hard-to-reach populations because the costs of recruiting sufficient sample sizes to produce reliable estimates tend to be cost prohibitive. The authors implemented a novel r…
Risk, Resilience, and Smoking in a National, Probability Sample of Sexual and Gender Minority Adults, 2017, USA
Background. There are well-documented inequities in smoking between sexual and gender minority (SGM; e.g., lesbian, gay, bisexual, and transgender [LGBT]) and straight and cisgender people. However, there is less information about risk for and resilience against smoking among SGM people. Such information is critical for understanding etiology and developing interventions. Aims. To conduct a within-group assessment of risks and resiliencies relati…
A Multidimensional Model of Sexual Empowerment Among Young Black Men Who have Sex with Men
Sexual Empowerment Among Young Black Men Who Have Sex with Men
Sexual empowerment represents an important HIV intervention strategy, yet limited attention has examined the multidimensional nature of sexual empowerment in prior studies. Using a sample (n = 465) of young Black men who have sex with men (MSM), we used confirmatory factor analysis (CFA) to test a multifactorial operationalization of sexual empowerment. CFA indicated that a bifactor model was best suited to characterize the sexual empowerment fac…
Cigarette pack messages about toxic chemicals
NCT02785484
Psychometric assessment of three newly developed implementation outcome measures
BACKGROUND: Implementation outcome measures are essential for monitoring and evaluating the success of implementation efforts. Yet, currently available measures lack conceptual clarity and have largely unknown reliability and validity. This study developed and psychometrically assessed three new measures: the Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM), and Feasibility of Intervention Measure (FIM). MET…
Negative affect, message reactance and perceived risk
Pictorial cigarette pack warnings increased quit intentions by increasing negative affect. Message reactance partially attenuated this increase in intentions. The opposing associations of negative affect and reactance on perceived risk may explain why pictorial warnings did not lead to observable changes in perceived risk
Understanding how perceptions of tobacco constituents and the FDA relate to effective and credible tobacco risk messaging
As the FDA continues their regulatory and messaging activities, they should expand both the breadth and availability of constituent-related information, targeting these efforts to reach all segments of the U.S. population, especially those disproportionately vulnerable to tobacco product use and its associated negative health outcomes
Public understanding of cigarette smoke constituents
Many people were unaware that burning the cigarette is the primary source of toxic constituents in cigarette smoke. Constituents that may most discourage cigarette smoking have familiar names, like arsenic and formaldehyde and do not start with a number or end in ene/ine. Our findings may help campaign designers develop constituent messages that discourage smoking
A Mediational Model of Racial Discrimination and Alcohol-Related Problems Among African American College Students
The results suggest that, for African Americans whose drinking leads to drinking-related problems, discrimination and poor affective self-regulation are highly relevant and predictive factors, especially for men
Emotional stress-reactivity and positive affect among college students
Multiple theories posit that people with a history of depression are at higher risk for a depressive episode than people who have never experienced depression, which may be partly due to differences in stress-reactivity. In addition, both the dynamic model of affect and the broaden-and-build theory suggest that stress and positive affect interact to predict negative affect, but this moderation has never been tested in the context of depression hi…
Interactive Effects of Discrimination and Racial Identity on Alcohol-Related Thoughts and Use
The interrelationships among racial discrimination, non race-based rejection, racial identity (RI), and alcohol cognitions and use were assessed in this research. In Study 1, individuals who experienced overt discrimination and who were high in RI were less likely than those low in RI to meet criteria for alcohol abuse disorder. In Study 2, discrimination and rejection were causally related to a faster reaction time in a lexical decision task to …
