therapy to manage depression regardless of intervention type, duration, or intensity. However, in the future reviews randomized trails using a larger sample size are required to increase the consistency of study results, thereby maximizing the external validity in order to generalize study…

assignment of control group subjects. The use of control group will increase the strength of the design. Good pre-test data will provide improved analysis and results. As subjects are not selected randomly may create threats to internal and external validity. 2. After only non equivalent control group design –All groups are treated equal after the independent variable is introduced in this design. This design is suited very well to study impacts of natural and manmade disaster. 3. Time series…

What are the limitations of this research in addition to those you identified with respect to the research strategy and design (e.g., researcher-experimenter effects)? Can you generate alternative interpretations of the researcher 's results? [Note: Please make sure you discuss 2 threats to internal validity and 1 threat to external validity] (25…

was supposed to. Also, threats of selection bias were introduced into the study, because participants were not randomly selected and the study used health professionals who tend to be more health aware. In addition, the study had threats to external validity specifically in the selection treatment interaction. The study only included Health Professionals, aged 40 to 75 years (1986-1994) and registered nurses who resided in 11 large states, aged 30 to 55 years (1980-1994). Consequently, the…

A within subject’s experimental design, compared the perceived differences in length of different sized paperclips on different body parts. The perceived distance of the paperclips, were rated on a scale of 0 to 2; zero meaning equal, one meaning shorter and two meaning longer. There were three conditions; the Finger-Wrist condition, the Finger-Forearm condition, and the Wrist-Forearm condition. 20-psychology students participated in the study. All 20 participants participated in all three…

E encountered in his study was one of validity. Among the tests Dr. E used for data collection were the food diaries and the Exercise Observation Sheet. The former had a good reputation but as far as Dr. E. knew the test had never previously been used among older adults as he used it in this…

This shows that positive biases likely exist in favor of the IDPs; thus, the previous findings that positive biases exist in favor of disabled people whose disabilities were caused by external factors (Bordieri & Drehmer, 1986), can be generalized to people who experienced distressing life circumstances caused by external factors, but which did not necessarily result in a disability.
