Resilient Connections
Research on dementia care partners often emphasizes the dyadic relationship, overlooking broader social networks that shape care partners’ well-being and resilience. This study examines how social network composition and quality influence care partner outcomes. We conducted ego-centric social network structured interviews with 179 unpaid care partners of individuals living with dementia. We used regression models to test our hypothesis, with hier…
A Latent Profile Analysis of Dementia-Related Anxiety
Cultural normative beliefs in the U.S. as a determinant of negative dental experiences and dental anxiety
Dental anxiety, a predictor of both dental treatment avoidance and health outcomes, has been linked with early negative dental experiences. The causes of this relationship remain largely unexplored. This study provides a preliminary exploration of within-cultural variations of dental normative beliefs on the perception of negative dental experiences and the subsequent experience of dental anxiety in the U.S. A sample of 190 U.S. adults recruited …
A test of pre-exposure spacing and multiple context pre-exposure on the mechanisms of latent inhibition of dental fear
It is hypothesized that spaced pre-exposure and pre-exposure in multiple contexts will increase the engagement of the mechanisms of expected relevance and attention and increase the latent inhibition of dental fear. It is expected that the findings will add to theory on fear learning and provide information to aid the design of future interventions that leverage latent inhibition to reduce dental phobia
A study protocol testing pre-exposure dose and compound pre-exposure on the mechanisms of latent inhibition of dental fear
The proposed study will test whether pre-exposure dose and compound stimulus presentation change expected relevance and attention to the pre-exposed stimulus, and thereby enhance latent inhibition of dental fear. If found, the results will add to our theoretical understanding of the latent inhibition of dental fear and inform future interventions for dental phobia prevention
Perceived Balance, Balance Performance, and Falls Among Community-Dwelling Older Adults
Objectives: To examine the extent to which older adults’ perceived balance, a balance performance test, and fear of falling (FOF) were associated with falls in the last month. Methods: The Health Belief Model served as the theoretical framework. A retrospective, cross-sectional, secondary analysis using data from the National Health and Aging Trends Study was conducted ( N = 7499). Results: Multiple logistic regression analysis revealed that the …
Study protocol of an investigation of attention and prediction error as mechanisms of action for latent inhibition of dental fear in humans
Dental phobia negatively affects the dental health and overall health of individuals. This study aims to determine the mechanisms through which pre-exposure retards conditioned dental fear acquisition, recall, and retention. A randomized control trial will be used to identify these mechanisms so that they can be precisely targeted and maximally engaged in preventative efforts
Profiles in Dementia-Related Anxiety
The resulting profiles point to several factors associated with elevated anxiety about ADRD, which do not fully match the risk factors for ADRD
Physical Activity Among Predominantly White Middle-Aged and Older US Adults During the Sars-CoV-2 Pandemic
Background: The first COVID-19 case in the US was diagnosed late January 2020. In the subsequent months, cases grew exponentially. By March 2020, SARS-CoV-2 (the novel coronavirus that causes COVID-19) was a global pandemic and the US declared a national emergency. To mitigate transmission, federal guidelines were established for social and physical distancing. These events disrupted daily routines of individuals around the world, including Ameri…
The Performance of Multivariate Methods for Two-Group Comparisons with Small Samples and Incomplete Data
In intervention studies having multiple outcomes, researchers often use a series of univariate tests (e.g., ANOVAs) to assess group mean differences. Previous research found that this approach properly controls Type I error and generally provides greater power compared to MANOVA, especially under realistic effect size and correlation combinations. However, when group differences are assessed for a specific outcome, these procedures are strictly u…
Psychosocial barriers to pre-exposure prophylaxis (PrEP) uptake
Several challenges have emerged in ensuring uptake of preexposure prophylaxis (PrEP) for HIV prevention. By applying the health belief model, the present study assessed associations between novel psychosocial variables and PrEP use among gay and bisexual men. Logistic regression analyses indicated that heterosexual self-presentation, sexual risk, PrEP conspiracy beliefs, and perceived peer PrEP use were positively associated with PrEP use. Greate…
Multivariate Models for Normal and Binary Responses in Intervention Studies
Use of multivariate analysis (e.g., multivariate analysis of variance) is common when normally distributed outcomes are collected in intervention research. However, when mixed responses—a set of normal and binary outcomes—are collected, standard multivariate analyses are no longer suitable. While mixed responses are often obtained in intervention studies and analysis models that can simultaneously include such outcomes are available, we found ver…
Applied Multivariate Statistics for the Social Sciences
Now in its 6th edition, the authoritative textbook Applied Multivariate Statistics for the Social Sciences, continues to provide advanced students with a practical and conceptual understanding of statistical procedures through examples and data-sets from actual research studies. With the added expertise of co-author Keenan Pituch (University of Texas-Austin), this 6th edition retains many key features of the previous editions, including its bread…
Distinguishing Between Cross- and Cluster-Level Mediation Processes in the Cluster Randomized Trial
For the cluster randomized trial, the treatment, implemented at the cluster level, may be hypothesized to impact a final outcome of interest via a mediating variable, with the mediator and outcome being measured typically at the participant level. Two opposing views-one that allows the mediation process to flow through a participant-level mediator and one that does not-have been presented in the literature. We integrate these perspectives and arg…
Poverty, Race, and Parental Involvement During the Transition to Elementary School
Using multilevel models of data from the Early Childhood Longitudinal Study-Kindergarten Cohort ( N = 20,356), the authors find that parental involvement in education partially mediates the association between family poverty and children's math and reading achievement in kindergarten, but differences exist across race. In Asian families, poor and nonpoor children have similar levels of achievement. Poverty is not related to Black children's parti…
The Performance of Methods to Test Upper-Level Mediation in the Presence of Nonnormal Data
A Monte Carlo study compared the statistical performance of standard and robust multilevel mediation analysis methods to test indirect effects for a cluster randomized experimental design under various departures from normality. The performance of these methods was examined for an upper-level mediation process, where the indirect effect is a fixed effect and a group-implemented treatment is hypothesized to impact a person-level outcome via a pers…
The Incidence of “Causal” Statements in Teaching-and-Learning Research Journals
The authors examined the methodologies of articles in teaching-and-learning research journals, published in 1994 and in 2004, and classified them as either intervention (based on researcher-manipulated variables) or nonintervention. Consistent with the findings of Hsieh et al., intervention research articles declined from 45% in 1994 to 33% in 2004. For nonintervention articles, the authors recorded the incidence of “causal” statements (e.g., if …
A Comparison of Single Sample and Bootstrap Methods to Assess Mediation in Cluster Randomized Trials
A Monte Carlo study examined the statistical performance of single sample and bootstrap methods that can be used to test and form confidence interval estimates of indirect effects in two cluster randomized experimental designs. The designs were similar in that they featured random assignment of clusters to one of two treatment conditions and included a single intervening variable and outcome, but they differed in whether the mediator was measured…
Men's restrictive emotionality
Using Kennedy-Moore and Watson’s cognitive-evaluative model of emotional expression and nonexpression, in the current study the authors investigated the relationship between men’s restrictive emotionality and other emotion-related constructs. Among the emotion-related variables represented by the above model, negative attitudes toward emotional expression were found to be most closely associated with men’s restrictive emotionality. In addition, r…
A preliminary examination of the "Real Men. Real Depression" campaign
This study reports on a preliminary evaluation of the National Institute of Mental Health (NIMH)-sponsored “Real Men. Real Depression” (RMRD) campaign. Two- hundred-nine men with a range of help-seeking attitudes and gender-role conflict (GRC) reviewed the RMRD brochure, a similar brochure excluding
A Comparison of Methods to Test for Mediation in Multisite Experiments
A Monte Carlo study extended the research of MacKinnon, Lockwood, Hoffman, West, and Sheets (2002) for single-level designs by examining the statistical performance of four methods to test for mediation in a multilevel experimental design. The design studied was a two-group experiment that was replicated across several sites, included a single intervening variable and outcome, and assumed that the effects of the treatment and mediator were consta…
