Observational study

The study design of the Evans study was based upon the use of both direct interview and observational study methods. For the direct interview methods, social demographic data, medical variables, employment status, and subjective indicators were obtained via personal interview Interviewers were trained during a three-day training session to ensure uniform interview processes. Completed interviews were obtained from 90% of eligible patients (Evans et al, 1985). The responses to these interview questions was then compared to the existing indexes: the index of Physiological Effect, the Index of Overall Life Satisfaction, and the Index of Well Being (Evans et al, 1985). Within the Evans study observational study methods were used to extract medical…

behavior among college students, we have compared two waves of data, analyzing different times and days; however, the location of the study remained the same: Game room. The first wave of data analyzed the flirting behavior of students in the game room at 10am on a Monday. The following wave demonstrated the flirting behavior of students on a Thursday afternoon. The data analyzed during this study suggests that college students display more flirting behavior in between classes from 12-1 than to…

administration of PN on growth outcomes. Moyses et al showed that early PN reduced the time to regain birthweight by (a mean) 2.2 days [95% confidence interval (CI) 1.1 to 3.2 days] in RCTs and 3.2 days (95% CI 2.0 to 4.4 days) in observational studies. The maximum percentage weight loss with early PN was lower by (a mean) 3.1% (95% CI 1.7% to 4.5%) for RCTs and by 3.5% (95% CI 2.6% to 4.3%) for observational studies. Early PN also improved weight at discharge or 36 weeks postmenstrual age by (a…

Furthermore, with the composite end point of death/MI/stroke there was no interaction between diabetics and non- diabetics with any of the revascularization strategies (p=0.65). With introduction of drug eluting stents(DES) in clinical practice, superiority of effectiveness of DES over BMS have been largely demonstrated in head to head comparison in several RCT as well observational studies and meta-analysis 15-19, therefore, we would expect a substantial improving in PCI results over CABG…

In my opinion, observational studies has its disadvantages. By simply observing an individual, this would not be truly reliable, there can be many factors that can influence the researcher to come to a conclusion that someone is happy or not without fully getting in depth. Observational reports in many cases also turns out to be description of events, rather than explanation. It would also be difficult to observe an individual for one day and come to a conclusion that he is happy. This process…

to determine the relationship whether low social support among the elderly increases risk of depression is a quantitative observational study. This type of study involves data that can take on numerical values (Salazar, Crosby & Diclemente, 2015). The reason this type of research will be used in this study because it involves measuring frequency of responses or written responses that can be quantified. For instance, in this study the data collection process will include a generated…

Building on this research, one could vary the data by including more high school students from different backgrounds and socioeconomic statuses. Finding out how these factors contribute to the number of AP classes taken and cumulative GPA will increase the effectiveness of this observational study. The limitation of the research was that many of the students who took the survey were from Ms. Moneypenny’s AP Statistics class, and other AP classes, as listed in the Introduction. This gave the data…

As a prospective, observational cohort study, this study assesses the relationship between levels of cardiorespiratory fitness (CRF) and rates of acquiring and surviving a cancer diagnosis over Medicare age (≥65 years old). The sample (n=13,949) included men who participated in the Cooper Center Longitudinal Study and had Medicare part A and B claims of prostate, lung or colorectal cancer between 1999 and 2009. Anthropometric measurements were taken before the protocol, including height, weight,…

This observational study compares the parenting styles and behavioural patterns of two parents from similar demographics, one married and one a single parent. The goal is to determine whether this distinction would account for a difference in style. Both observation sessions were conducted in similar fashion: at the same time of day, in similar settings, and with minimal intrusion from the observer. This was in order to limit the possibility of external factors affecting the study. For the…

Is leaving makeup on overnight really that bad? Many people can relate to the lack of motivation to take off makeup after a long night out or an exhausting day. However, this can be detrimental to the health of your skin. Although one slip up will not cause a breakout, clogged pores and wrinkles, a study conducted in London 2013 shows how repeated nights with makeup can cause drastic changes to the overall appearance and health of your skin. A woman named Anna Pursglove decided that she wanted…
