We are happy to share that a manuscript using data from the affectionate communication study has been published. Within twin pairs, identical twins were more highly correlated for expressed and received affection than fraternal twins, suggesting genetic influences play a role in affection. Using an ACE model, which is used in twin studies to estimate […]
In the follow-up survey, we were interested in whether the number of individuals in a household during lock-down/shelter-in-place has an effect on people’s mental health status. We were particularly curious about whether individuals with children are more worried during this unprecedented time.

The pervasive, damaging nature of posttraumatic stress disorder (PTSD) presents enormous clinical challenges. Understanding the relationship between patients’ perceptions of PTSD symptoms and resilient coping strategies may prompt investigation of clinical interventions that improve adaptive, resilient coping skills. In this study, we examined whether changes in resilient coping were related to changes over time in […]
This survey is being sent to parents of twins age 13 and younger. This survey will examine how the COVID-19 pandemic is impacting families.
The purpose of this survey study is to examine the impact of the COVID-19 pandemic and corresponding social restrictions in place on the daily life and feelings of WSTR twin pairs. Given the widespread statewide social restrictions put in place, it is possible that people’s perceptions and normal interactions within their neighborhoods may have changed. […]
Purpose of the study In light of the impact of the COVID-19 pandemic and the corresponding social restrictions to society, we followed up with a sample of our participants to see how they are impacted by the recent events. We would like to thank the WSTR twins for their participation and continued support of the […]
In our recent COVID-19 survey, we asked participants several questions about their exposure to the COVID-19 virus. Most participants reported not having been diagnosed with COVID-19, with very few participants reported having household and/or family members diagnosed with COVID-19. However, 42.69% participants reported knowing at least one friend (and/or classmate) who was diagnosed with COVID-19. More […]
Using a twin study design, we explored the extent to which affectionate communication is a heritable behavioral trait. Participants (N = 928) were 464 adult twin pairs (229 monozygotic, 235 dizygotic) who provided data on their affectionate communication behaviors. Through ACE modeling, we determined that approximately 45% of the variance in trait expressed affectionate communication is heritable, whereas 21% […]
In response to the COVID-19 pandemic, many social restrictions have been put in place in the hopes to slow down the spread of the virus. As a result, many of us have had to make changes in our daily lives accordingly. We examined whether self-perceived change in the amount of physical activity and sleep is […]
We were interested in examining the extent to which the COVID-19 pandemic affects mental health. Participants were asked to respond to a number of survey items designed to assess depression, stress, and anxiety.
Background: There has been increased interest in the interplay of genetic and environmental factors in the development of problematic alcohol use, including socioeconomic conditions of the neighborhood. Using a co-twin design, we examined the extent to which contributions of genetic, shared environmental, and unique environmental influences on hazardous drinking differed according to levels of neighborhood […]
This research study is being done to examine the impact of COVID-19 on daily activities such as sleep and physical activity. In addition to the risk of COVID-19 infection, statewide restrictions such as stay-at-home orders have resulted in drastic impacts to people’s daily lives. We will collect one week of data 10 times over a […]
In March 2020 we developed a survey to collect information about COVID-19 from all adult members enrolled in the Washington State Twin Registry. The first survey completed is the baseline survey, and a follow-up survey will be sent out beginning in April 2020.
Purpose of the study In light of the impact of the COVID-19 pandemic and the corresponding social restrictions to society, we aimed to examine the extent to which participants in WSTR are impacted by the recent events. Here is a brief summary of selected results. We would also like to thank the WSTR twins for […]
Asthma is the most prevalent chronic lung inflammatory disorder characterized by reversible airflow obstruction, affecting 358 million people worldwide, with aggravating factors like obesity, attention‐deficit/hyperactivity disorder, socioeconomic status like poor healthcare affordability and facility, smoking and alcohol intake. RNA sequencing (RNA‐seq) in atopic asthma, childhood asthma and adult‐onset severe asthma has improved our understanding of cellular and […]
