The study you're describing seems to be a quantitative follow-up to a previous qualitative study on the psychosocial and lifestyle impacts of Spontaneous Coronary Artery Dissection (SCAD). The study has three main objectives: Quantify the psychosocial and lifestyle impacts of SCAD: This involves using statistical methods to measure the prevalence and importance of these impacts. This could be done through a survey where participants rate the extent of various impacts on a scale. The responses can then be analyzed to determine the frequency and relative importance of each impact. Identify characteristics of SCAD survivors most likely to experience these impacts: This involves analyzing the data to find patterns or correlations between certain characteristics (like age, gender, lifestyle factors, etc.) and the likelihood of experiencing these impacts. This could be done using regression analysis or other statistical methods. Investigate the association between SCAD impacts and survivors' current anxiety and depression: This involves examining whether there's a relationship between the impacts of SCAD and levels of anxiety and depression. This could be done by comparing the anxiety and depression scores of those who report high SCAD impacts with those who report low impacts. Statistical tests like t-tests or ANOVA could be used to determine if the differences are significant. In all these steps, the data collected from the online survey would be crucial. The survey should
