Construct Development, Scale Creation, and Process Analysis
The purpose of this paper is to find a construct in which I would like to measure. The construct of my choice will be developing a test that measures depression in men and women who have been diagnosed with a terminal illness. An operational definition of depression will be provided using three peer review journal articles as sources and references. In addition to that a method of scaling will be selected to justify my selection. I will then be proposing how I will be norming the instrument. Depression is a medical illness that causes an individual to a have a persistent feeling of loss of interest and sadness. Depression affects how an individual thinks, feels and behaves, and in addition to that depression causes physical symptoms as well. Depression leads to a variety of physical and emotional problems. An individual may have trouble doing day-to-day activities; it can also make an individual feel, as life is not worth living anymore. Depression is more than just feeling blue, and it is not a weakness, nor can an individual just snap out o it. Depression is considered a chronic illness that will require long-term treatment for some individuals. Most people with depression begin to feel better after psychological counseling, medication, and other forms of treatment. Where are your references??? This is a lot of information without a references… The Hamilton Depression Scale is a test that measures the severity of an individual’s depressive symptoms. This test is administered to individuals who have already been diagnosed with depression (Prasad, Udupa, Kishore, Thirthalli, Sathyaprabha, Gangadhar, 2009). Another named used for this test is the Hamilton Rating Scale for Depression. The Hamilton Depression Scale is used assesses the severity of depressive symptoms in both adult and child. In addition to measuring the severity of the depression, medical professions use it to determine the antidepressant medication and its dosage (Prasad, Udupa, Kishore, Thirthalli, Sathyaprabha, Gangadhar, 2009). Depending on the version that is used there can be a number of 17 or 21 items used, in which the interviewer uses for the rating (Stage, Middelboe, Pisinger, 2003). In addition to the interview with the patient other information is collected and utilized in preparing the ratings. Information on the patient’s records, family, and friends can also be utilized to formulate results. During the interview the entire process has to be even-tempered and relaxed. There are no specific questions in which the health professional shall ask, the version that contains 17 items is used more commonly than the 21 item version (Prasad, Udupa, Kishore, Thirthalli, Sathyaprabha, Gangadhar, 2009). The 21 item version contains an additional four items that measure symptoms, such as obsession and paranoia, rather than just the depressive symptoms (Prasad, Udupa, Kishore, Thirthalli, Sathyaprabha, Gangadhar, 2009). Some examples of the items that interviewers must give ratings on are insomnia, suicide, guilt, depression, retardation, anxiety, work related problems, loss of libido, loss of weight, and gastrointestinal symptoms. To get the overall score of depression health professions should look for gloominess, hopelessness the tendency to cry and pessimism. To get the rating on suicide health professions should look for suicidal thoughts and ideas, and suicide attempts (Prasad, Udupa, Kishore, Thirthalli, Sathyaprabha, Gangadhar, 2009). Below you have centered your paragraph… not correct APA format. Instruments that are used for self-rating are available, but have not been fully explored. Hamilton Subscale and Bech-Refaelesen Melancholia Scale were evaluated compared against each other, along with the clinical version. The property of each score was tested by item response theory model; they were also tested for their sensitivity. The some of the scores in the...
