Realiability and Validity Rosenburg Scale

dependableness and rigour of the Rosenberg Self Esteem Scale Texas A&M University Psychology 203 institution The purpose of our study was to evaluate the reliability and rigor of the Rosenber Self-Esteem home craps. Reliability is simply whether the flierment brute you ar utilize meters something consis gotly. For example does the same strain show the same results when administered repeatedly. Validity is the facet of a bar tool that signifies its mensuration what it says it does.A valid turn out rates what it says its measuring. so far you can fox a raise that is veritable and non valid, for example if a teacher administers a spelling test that the savant has to complete on the ready reckoner in a five arcsecond time period. A student whitethorn get the same score over and over again, indicating its reliable, exclusively it may not be valid because what if that student was s embarrassed at typewrite but knew how to spell every word. The test would n ot be valid because its not measuring just spelling as mean but also typing speed.Both reliability and validity argon any important(p) in and study because if the research instruments are not reliable and valid, then the results of your examine will always be in question. Method All ninety-nine A&M students (N=99) that participated in the sight were in the same statistical written material course and were required to take the subject as part of the course curriculum. The canvass consisted of 24 males and 75 females, with the aver climb on age of these participants macrocosm around 20 geezerhood old, ranging eachwhere from 19 to 24 (M=20. 7, SD=. 997). the adopt measured self-assertion by using ten percentage points from the Rosenberg Self Esteem Scale. The students were scored by taking the squiffy of all their responses to the ten questions. 10 diverse statements that the participant rated on a scale of 1 to 7, (1 world disagree strongly and 7 being agree stro ngly), the higher the score the higher the individuals conceit. The scale consisted of 5 revere coded items an example of a normal item is on the whole I am satisfied with myself.A reveree coded item is an diametral statement for example is I receive I do not corroborate much to be proud of. Results The 10 item subscale from the Rosenberg Self-Esteem scale appeared to have good versed consistency, (? = . 90). All the reexamine question appeared to be worth belongings in fact the deletion of any of the questions would have resulted in a swallow important score. All 99 participants (N=99) responses to the 10 item study were mediocred together and the self-esteem score for all the participants had ranged from 2. 6-7 with a mean of 5. 4 (M=5. 4, SD=1. 08).The frequency dispersal of the average self-esteem scores, illustrated on the histogram, portrays a distribution that is pretty normal but approximately negatively. This negative distributions means that the participants more a great deal had high self-esteem scores than low scores. In fact no participants had a self-esteem score lower than 2. 6. intervention To ensure that the espouse instrument apply in this study was actually measuring self-esteem we took a measure of Cronbachs alpha ( or ? ), which is a special measure of reliability known as indwelling consistency.The internal consistency reliability of surveil instruments (e. g. Rosenberg Self-Esteem scale), is a measure of reliability of different survey items intended to measure the same characteristic, in this case self-esteem. For example, in that location were 10 different questions related to self-esteem level. Each question implies a response scale from 1 to 7. Responses from the group of the 99 respondents have been obtained. In reality, answers to different questions falsify for each particular respondent, although the items are intended to measure the same aspect or quantity.The smaller this variability (or stronger the corr elation), the greater the internal consistency reliability of this survey instrument. So in this survey the self-esteem scale was found to be highly reliable (10 items = . 90). We can safely assume that our survey items reliably measure self-esteem levels. iodin other way we might have assessed reliability would have been to get all the participants to take another Self-Esteem survey of similar design but with different questions.In social sciences in particular do sure that your research has create validity is very important. Construct validity has traditionally been defined as the experimental materialization that a test is measuring the construct it claims to be measuring, in laymens hurt does the measuring tool actually measure the theory under examination.? Am I actually measuring what I signify I am measuring? In our example construct validity would be how well dos our observational tool (Rosenberg self-esteem scale) assess one attribute of self-esteem.We could of inter -correlated measures of depression with the measures of the revers coded items (SE3,SE5,SE8,SE9,SE10), because depression and the revers coded items have similar underlying constructs. last the low correlation amid efflorescence and self-esteem in our study strengthens our construct validity. I believe it strengthens the overall solve because common theories of self-esteem have no reliable and valid evidence correlating the two, so we can assume that construct between the two would be low, and if our study showed a strong relationship it would be casue for questions.
