Executive Function Performance Test - Essay Example Reliability is the degree to which an instrument measures the same way each time it is used; it may be estimated by the agreement between examiners and its internal consistency. In the study, interrater reliability was measured using intraclass correlation coefficients and Cronbach’s alpha for each of the tasks, and to correlate each of the test domains with the total score. Validity is related to how close the results, based on the measurement, are related to the truth. In the present study, validity was measured by comparing the performance across the three groups, founded in the results of measurements. In addition, the scale was compared and correlated with other neuropsychological measures which are known to assess executive functions. According to the results, shown in table No 1 of the original document, the demographic characteristics were similar in the study groups. The control individuals were younger, but there was no statistical significance. Patients with moderat e stroke had higher scores in the EFPT tasks, followed by patients with mild stroke, and control individuals. Both the EFPT total score and each of the executive functions showed a similar trend. These results confirm the hypotheses of the study. The study has the strength of evaluating a scale that measures instrumental tasks and the level of assistance affected individuals need in these tasks. As with other scales, researchers are measuring important characteristics of this instrument: validity and reliability.

Leadership in Public Health - Assignment Example There is, therefore, need for the Public Health System to develop own leadership theory that addresses the theoretical gaps in current leadership literature. The proposed Personal Public Health Leadership Theory is considered sufficient for public health organizations to attain the desired outcome. An evaluation plan is, however; necessary to determine the effectiveness of the theory, and the quasi-experimental method is considered the most appropriate method. Overall, deficiency in leadership is still evident in the sector of Public Health today; hence more effort is needed to address this major issue. Leadership is an important aspect of Public Health. This has gained more significance in the past years, as various studies on leadership confirm the importance of leadership aspect. The sector of Public Health lacks sufficient literature on leadership. The limited research activities in this area in the field of Public Health can be considered the major cause of this leadership literature deficiency. On the other hand, evidence shows that there is a relationship between leadership and quality of services in an organization (Farrell, 2001). For this reason, it is evident that the quality of the health care system depends on the kind of leadership practice. However, due to insufficient literature to guide leadership in the Public Sector, it means that the quality of services therein is more likely to be compromised. Therefore, this necessitates the adoption of more research on leadership in Public Health.  In this paper, there is a literature review on the aspect of leadership. Ther e are many theoretical gaps in the leadership literature that have been identified, and this is a proof of the unreliability of such literature for application in the Public Health sector. In order to, therefore, adopt an effective leadership theory for the Public Health sector, there is need to address the theoretical gaps in the current literature.
