...Application and appropriateness | Advantages | Disadvantages | Internal consistency | Internal consistency is used to make sure that multiple constructs that are measuring a variable produce identical results. An example of the test would be a questionnaire where the respondent is asked questions about cigarettes and he responds that he does not like cigarettes, has not smoked in the past, and disagrees with the statement “I like smoking cigarettes”. This would show a good internal consistency of the questionnaire. | The advantages of internal consistency reliability are that it makes sure that a test is not redundant and that each part of the test is helping to measure the target variable. | The disadvantages of internal consistency reliability are that it does help in understanding if the target variable is being measured by all the questions, but doesn’t say whether it is being measured accurately. | Split-half | The split half reliability test is a test comprising of two sections. Each section’s scores are compared to test for consistency. It the two scores are consistent, then the two tests are approximately measuring the same variable. The identity of this test is that each section is the exact same. | The advantage of this test is that it makes sure the test is robust in the sense that it is able to measure the same construct regardless of the sample. | | Test or retest...

...ETHICAL BEHAVIOR CONSTRUCT: MEASUREMENT AND PRACTICAL IMPLICATIONS Branko BUČAR, Faculty of Economics, University of Ljubljana Mateja DRNOVŠEK, Faculty of Economics, University of Ljubljana Address all correspondence to: Branko Bučar University of Ljubljana, Faculty of Economics Kardeljeva ploščad 17, 1000 Ljubljana, Slovenia Email: branko.bucar@uni-lj.si ABSTRACT The primary concern of the article is to validate the scale of ethical behavior construct developed in previous research. We examined the internal consistency of the modified Newstrom and Ruch’s (1975) scale for the measurement of the ethical behavior construct. We based this study on the model by Akaah and Lund (1994) about the influence of personal and organizational values on ethical behavior in the entrepreneurial context. We concluded that the six-dimensional construct of ethical behavior cannot be supported in the same way as proposed by Akaah and Lund (1994) and proposed several modifications to the measurement scale.

...groups of individuals, both human and nonhuman, in the society. In psychology, constructs refers to ideals or variables that is impossible to quantify since they do not possess any measurable attribute. Motivation, intelligence anger, personality, attachment, love and fear are some example of construct. Personality psychology comprises of characteristic patterns of thoughts, feelings, and behaviors that shapes a person. One of the most prominent issues in personality psychology is the measurement of personality construct. This paper aims at looking into the measurement of construct with regard to multitrait-multimethod matrix developed by Campbell and Fiske and other single methodology. The multitrait-multimethod (MTMM) matrix is an approach for the examination of Construct Validity. It was developed by Campbell and Fiske (1959). According to Campbell and Fiske, there are six major considerations when examining a construct's validity through the MTMM matrix. The six considerations are as follows. The first consideration is the evaluation of convergent validity, which is used to design tests that measures and shows how construct relate to each other. The second consideration is the evaluation of divergent validity. In this case, the construct being measured by a test should not correlate highly with different constructs. The third consideration is the trait-method unit whereby each test used in construct measurement is considered as trait-method unit. The fourth is the Multitrait-multimethod whereby...

...Kelly believed that people use personal constructs to anticipate everyday issues in their lives. These constructs are used by each person individually to “construe” or explain certain experiences. These constructs are an idea that people use when they need a way to explain something they went through. It also helps people predict what is going to happen or what they will go through when they go through an experience, it helps them predict reality. If a construct is correct in its prediction then it is deemed useful, however, if that construct was wrong in its prediction it must be revisited and thought upon again. These constructs are usually label that people use to give a name to events that occur in their environment. People will then test these new labels that they have created through continuing events that will either confirm the construct or deny it. People try to arrive at a construct system that closely resembles reality and to arrive at this kind of system takes a long period of trial and error. Kelly believes that someone’s personality is the collection of constructs that they create for all of the people people in their lives and...

The Transtheoretical Model The Transtheoretical Model has tremendously helped the health field progress to more inclusive approaches to research and other practices [2]. In the 1970s, James Prochaska laid the foundations for this model. In the 1990s, two scales were developed using the model [2]. This model is used for health promotion because it enables people to make behavioral changes and improve their health. The Transtheoretical Model is and will continue to be one of the most popular in the behavior change field due to its uniqueness and effectiveness. The Transtheoretical Model has six constructs with two being broken down into smaller sections. The first construct demonstrates that statement; which is the stages of change. These five stages provide a temporal or time dimension and imply that change occurs over time. The five stages are: precontemplation, contemplation, preparation (these...

...Personal Construct Terrance J. Banks COM321 – Communication Theory (BHE 1349A) Instructor Donald Olsen December 16, 2013 Personal construct perceive of someone view and build their relationship on it. One may set their personal standards world which leads to one history and one predisposition on life. A personal construct identify the opposite extremes and similar of people behavior and style. We place ourselves along lifestyles standards on our family, friends and colleagues. It is also define people by the way they act in the company and decide that some people are extravert and others are introvert. Kelly (2009) stated, “A person is motivated to predict or anticipate what will happen to him or her. What moves people to act George A. Kelly (1905-1966) developed a highly influential theory of personality that described human beings as lay scientist who seek to organize or predict, and control their world”. Kelly says, people believe that a prediction is the drivers of our mind (Kelly, 2009). A construct has two extreme points; “happy-sad”, and we place people; at either one at some point in between (Kelly, 2009). A personal construct is the way we as people look at life, people, and our surroundings. Kelly (2009) stated, “A personal construct according to Kelly classifies his or her own world by developing personal constructs, which are characteristic ways of how some things are alike, and some things are different from one another”. Kelly says all constructs are bipolar...

...validity, discriminant validity, construct validity, test-retest reliability, and internal consistency reliability. What can researchers do to improve upon these different types of reliability and validity in a survey? Inter-Rater or Inter-Observer Reliability is used to assess the degree to which different raters/observers give consistent estimates of the same phenomenon. Test-Retest Reliability is used to assess the consistency of a measure from one time to another. Parallel-Forms Reliability is used to assess the consistency of the results of two tests constructed in the same way from the same content domain. Internal Consistency Reliability is used to assess the consistency of results across items within a test. Construct validity occurs when the theoretical constructs of cause and effect accurately represent the real-world situations they are intended to model. This is related to how well the experiment is operationalized. A good experiment turns the theory (constructs) into actual things you can measure. Sometimes just finding out more about the construct (which itself must be valid) can be helpful. Convergent validity occurs where measures of constructs that are expected to correlate do so. This is similar to concurrent validity (which looks for correlation with other tests). Discriminant validity occurs where constructs that are expected not to relate do not, such that it is possible to discriminate between these constructs. Convergence and discrimination are...

Email: mdjohn@umich.edu; tel.: +734-764-1259; fax: +734-936-0274. 2 Abstract A number of both national and international customer satisfaction barometers or indices have been introduced in the last decade. For the most part, these satisfaction indices are embedded within a system of cause and effect relationships or satisfaction model. Yet there has been little in the way of model development. Of critical importance to the validity and reliability of such indices is that the models and methods used to measure customer satisfaction and related constructs continue to learn, adapt, and improve over time. The primary goal of this research is to propose and test a number of modifications and improvements to the national index models. Using survey data from the Norwegian Customer Satisfaction Barometer (NCSB), we find general support for the proposed modifications. 1. Introduction Customer satisfaction has taken on national and international significance with the...

...Chapter 4 – Design Tools: Jackson Structured Programming (JSP) 4.1 Three Structured Constructs All programs can be constructed using only the three basic constructs. It is the concept of structured programming that a program should be developed using only these three basic constructs. It is not wrong to use the GOTO structure but it is discouraged, because programs with the GOTO structure are often classified as unstructured. The three basic constructs are: 1. Sequence 2. Selection 3. Iteration/Repetition 4.1.1 Sequence Construct In a sequence construct, the way the statements are placed implies the order in which the computer will execute the statements. The computer will interpret the statements in a left to right, top to bottom fashion. Consider the following: Calculate-Average Module DO Get Two Numbers Calculate Sum Determine Average Print Average ENDDO The sequence for the above module is straightforward. You get the two numbers, calculate the sum, determine the average and print out the result. If the statements are not in that sequence, the result obtained will not be the answer intended! Figure 4-1: Simple sequence The Calculate Average module is not a separate module away from the rest of the four modules below it. But it actually contains all the four modules. Each process (a rectangle) represents a component with their function/action...

...steps which need to be followed: 1.THE PLANNING PHASE This is where the aim of the measure needs to be decided on and stated. The characteristic or construct to be measured, what the measure will be used for, and the target group (population) for the measure will also need to be defined. Once this has been clarified, one can decide how the test scores will affect decisions (or what decisions can be made based on test scores). An important stage in planning is whether the performance is compared to a criterion or a group norm. In order to define the content of a measure, one needs to have a defined purpose of a measure. The construct needs to be operationally defined, by undertaking a literature review (research process) of the main theoretical viewpoints of the construct. The purpose of the measure is clearly vital, as it serves the basis for constructing the measure. In this phase, 'keying' is used ? where information is gathered about the 'aspects of the construct on which these groups usually differ'. (An Introduction to Psychological Assessment. Foxcroft and Roodt. P72). e.g. Items are needed to discriminate between individuals, so as to allow the assessor to view the various 'risk' groups. The format and number of each type of item is the next step in the planning phase. The format of the test will vary according to the construct being measured. There are open-ended items (no limits placed on the test-taker), forced-choice items (like multiple-choice, where careful decisions...

...Hull’s hypothetical constructs and intervening variables. In the first case, there is no room for intermediary cognitive processes between stimulus and response, outside the realm of simple associative learning. In the second case, there is lacking an explicit scientific means by which to objectively observe the theoretical cognitive mechanisms in question. However, E. C. Tolman was one of the first psychologists to suggest that intermediary cognitive processes could be deduced through the results of scientifically rigorous experimentation (Zentall, 2002). It is on this very basic proposition, that theoretical cognitive processes can be inferred by observing behavior, which most informs the developmental milestones in the formation of the cognitive perspective as a branch of psychology. Development of Cognitive Psychology The development of the cognitive approach as a mainstream psychological perspective is marked by four major milestones: 1) the shortfalls of the behaviorist perspective of psychology 2) the ability for abstract constructs to account for the aforementioned shortfalls 3) the bridging of abstract constructs with observable mechanisms through the medium of artificial intelligence and neuroscience 4) the realization that the representations and processes of cognition can be liken to the internal functioning of a computer. The behaviorism of the early 20th century could not account for many observable behaviors documented by psychologists of the time. For instance,...
