Revised on June 19, 2020. For concurrent validity, we hoped to achieve correlation coefficients of 0.4 or higher and ideally larger than 0.6. Question 1 asks “In general, would you say your health is □ Excellent □ Very Good □ Good □ Fair □ Poor.”. E.G. It is a parameter used in sociology, psychology, and other psychometric or behavioral sciences. Convergent validity reflects whether two proxy measurements capture the same underlying construct while concurrent validity reflects the correspondence between a proxy measurement and a criterion method when captured simultaneously … If the scores for each employee on both tests are closely related, then the new scale is said to have high concurrent validity. • criterion validity, (which includes concurrent and predic-tive validity); • construct validity (which includes convergent, divergent, factorial and discriminant validity) (Lynn 1986). Concurrent validity in this study is determined for physical activity by comparing the physical activity score on the SLIQ with the steps on a pedometer; it is determined for diet by comparing the raw diet score on the SLIQ with the diet score on the DHQ; it is determined for alcohol by comparing the raw alcohol component on the SLIQ with the alcohol score on the DHQ; and it is determined for stress by comparing the raw stress score on the SLIQ with the stress score on the SRRS. In the case of discriminant validity, you could show that there is no correlation at all. Discriminant validity (or divergent validity) tests that constructs that should have no … Some investigators believe a correlation between 0.0 and 0.25 represents a weak relationship, 0.26–0.50 a moderate relationship, 0.51–0.75 a strong relationship, and greater than 0.75 a very strong correlation. Two methods are often applied to test convergent validity. Construct validity means that a test designed to measure a particular construct (i.e. One hundred and ninety-three adults completed all the questionnaires allowing correlational statistics to be completed. report. The absolute value of the correlation for the stress component is the lowest of all the components, and we considered dropping it from the scale. Opinion on how a given level of correlation between 0 and 1 should be interpreted varies in the literature. Convergent validity and discriminant validity are never all-or-nothing constructs, and thus it is never possible to defi nitively “prove” the construct validity of a measured variable. Criterion validity (concurrent and predictive validity) There are many occasions when you might choose to use a well-established measurement procedure (e.g., a 42-item survey on depression) as the basis to create a new measurement procedure (e.g., a 19-item survey on depression) to measure the construct you are interested in (e.g., depression, sleep quality, employee commitment, etc. It mentions at the beginning before any validity evidence is discussed that "historically, this type of evidence has been referred to as concurrent validity, convergent and discriminant validity, predictive validity, and criterion-related validity." New comments cannot be posted and votes cannot be cast, More posts from the askpsychology community. Convergent validity is a subcategory of construct validity. These are discussed in detail in the Predictive validity section below. Convergent validity occurs where measures of constructs that are expected to correlate do so. In contrast to concurrent validity, convergent validity was consistently high across all comparisons in this study excluding WHR as measured by LS2D and Gulick tape. The Simple Lifestyle Indicator Questionnaire (SLIQ) remains the only short, easy-to-use instrument available for measuring cardiovascular lifestyle as a single construct. external validity of 0.77. [19]. Initial psychometric testing of its reliability, internal validity, and basic external validity testing was published in 2008 [10]. Press J to jump to the feed. Analysis. Another way of measuring convergent validity is to look at the differences in test scores between groups of people who would be expected to score differently on the test. Component scores are summed to give a SLIQ score from 0 to 10 (0 = very unhealthy, 10 = very healthy). The scoring template is shown in Supplementary Figure 2. The SRRS takes an interesting approach to assessing stress in a person’s life but one could argue there are more modern approaches, and perhaps we should have chosen one of those. The correlation coefficients reported in this study vary from 0.264 to 0.679. For example, let’s say employers have designed their own scale to assess the leadership skills of their employees. I'm studying for a psych research final right now, and I've been trying to understand and differentiate Concurrent Validity and Convergent Validity! Convergent validity is measured by comparing the instrument in question with another instrument that measures a related, but different, construct. Convergent Validity. People with a score of 5 out of 8 or higher had a 5 times higher likelihood of dying within 5 years. While lifestyle and health status are related, they would not be expected to have high correlation since a change in one may precede or follow the other rather than necessarily exist concurrently. It typically is estimated by correlating scores on a new measure with scores from an accepted criterion measure. Published on September 6, 2019 by Fiona Middleton. Sorry if this isn't the right place to post this but I can't think of any other subreddit. Construct Validity: Convergent vs. Discriminant. We recruited patients aged 40 and above from three different family physician clinics that are part of a practice-based research network and have participated in research studies previously. I think this might be what throwing me off most of all about it since those all are for the most part different things. Related Psychology Terms. Convergent validity tests that constructs that are expected to be related are, in fact, related. Marshall Godwin, Andrea Pike, Cheri Bethune, Allison Kirby, Adam Pike, "Concurrent and Convergent Validity of the Simple Lifestyle Indicator Questionnaire", International Scholarly Research Notices, vol. . More details on the SLIQ are in Section 2. ", "Convergent validity refers to the degree to which scores on a test correlate with (or are related to) scores on other tests that are designed to assess the same construct. However, the SLIQ measures the person’s assessment of their current stress level while the SRRS simply scores stress events in a person’s life over the previous year. Predictive validity; Concurrent validity; Convergent validity; Discriminant validity; I have to warn you here that I made this list up. Another way of measuring convergent validity is to look at the differences in test scores between groups of people who would be expected to score differently on the test. The only Convergent/ Concurrent validity findings available for the ILP must be derived from regression analyses conducted by Pulford and Sohal (2006). As the name suggests, concurrent validity relies upon tests that took place at the same time. ”, quantifies the strength of the linear relationship between two variables. E.G. The letters briefly explained the study and provided the phone number of the research assistant to be contacted if they were interested in taking part. If the scores for each employee on both tests are closely related, then the new scale is said to have high concurrent validity." Criterion validity evaluates how closely the results of your test correspond to the … Criterion validity. The overall SLIQ lifestyle score correlated reasonable well with the eight-question risk scale The chosen reference standard, and whether it is the most appropriate, is always an issue with validity studies. Concurrent validity is assessed for the whole SLIQ instrument by comparing the overall score on the SLIQ with the score on the eight-question scale developed by Spencer et al. It also collects detailed information on alcohol consumption [11, 12]. eaten on a weekly basis over the previous year. In this case, we used the responses to the first question on the SF36 which is a self-assessment of one’s health status. They give employees the scale to fill out on the same day as a similar, but longer and decades-old leadership test. Convergent validity is one of the topics related to construct validity (Gregory, 2007). Convergent validity is usually accomplished by demonstrating a correlation between the two measures, although it’s rare that any two measures will be perfectly convergent. Concurrent validity is determined by comparing the score on the instrument of interest; in this case the SLIQ, with the score on a reference standard—a measurement tool that is known to accurately measure that same construct. However, whilst concurrent validity compared a new measurement procedure with a well-established measurement procedure, both measurement procedures are new when testing for convergent validity. , Concurrent validity is one of the two types of criterion-related validity.

A) convergent validity B) discriminant validity C) criterion validity Apparently, the right answer is A), but I think you could still argue for C) in the following manner: Scores on the final exam is the outcome measure and GPA, amount of time spent studying, and class attendance predict it. In this current study, validity was assessed by determining the correlation coefficients between the component raw scores on the SLIQ and the appropriate referencestandards(DHQ,SRRS,Question1ontheSF36, andstepperdayonthepedometer).ANOVAwasconducted This study provides further psychometrics on the Simple Lifestyle Indicator Questionnaire (SLIQ), a short, easy-to-use instrument which measures all these lifestyle characteristics as a single construct. As the name suggests, concurrent validity relies upon tests that took place at the same time. , Categorically, a person is considered “unhealthy” if they have a SLIQ score of between 0 and 4, “intermediate” if the SLIQ score is between 5 and 7, and “healthy” if they score between 8 and 10 on the SLIQ. It was developed as a short and simple health measurement scale [10]. Utility, i.e. In order to efficiently measure some behaviours in clinical and research settings, shorter health measurement scales are developed and compared to the longer detailed assessments to determine if they can be used to realistically assess the particular behaviour or health issue. If they don’t, the questions might not be valid. , Convergent Validity. be at least moderately correlated with each other. In 2003, Hemphill [23] reviewed the literature that reported correlation coefficients and divided them into tertiles: one-third reported coefficients <0.2, the middle third reported coefficients between 0.2 and 0.3, and the upper third reported coefficients >0.3. The reference standards were a detailed Diet History Questionnaire (DHQ), the Social Readjustment Rating Scale (SRRS), the SF36 Health Status Questionnaire, and a survey of eight questions from a cardiovascular risk questionnaire. is in the range we were expecting. Assessments of the SLIQ sensitivity to change and its predictive validity are both underway. In 2010, with funding through the Healthy Aging Research Program of the Newfoundland and Labrador Centre for Applied Health Research, we conducted further validity testing. the degree of communication between two measurements at the same time, primarily the investigation of one exam's validity by comparing its outcomes with another correlated exam at the same time. Construct Validity: Convergent vs. Discriminant. Also, as anticipated, the LEAS-C was more strongly associated with emotion comprehension than emotion expression (Bajgar et al., 2005). The categorization of individuals as unhealthy/intermediate/healthy was assessed to determine if these three groups were from separate populations; that is, whether the mean and standard deviations of the SLIQ scores in these three groups were separated such that there was very little overlap. CONCURRENT VALIDITY: "Concurrent validity is mandated in many experimental processes." We expected a correlation coefficient in the range of 0.2 to 0.4. The SF36 is a health status measurement tool used in over 4000 published studies worldwide. Similarly, its correlation with the eight-question scale, which themselves have been shown to predict mortality, increases the SLIQ validity. Sorry if this isn't the right place to post this but I can't think of any other subreddit . Using a pedometer for three days has been shown to be highly correlated with the level of physical activity [20, 21]. Convergent Validity – When two similar questions reveal the same result. Some other types of validity are: Composite, Concurrent, Convergent, Consequential, Curricular and Instructional, Ecological, External, Face, Formative validity & Summative Validity, Incremental Validity, Internal, Predictive, Sampling, and Statistical Conclusion Validity. Both types of validity are a requirement for excellent construct validity. Criterion validity A measurement technique has criterion validity if its results are closely related to those given by Lifestyle issues including physical activity, diet, smoking, alcohol consumption, and self-reported stress have all been shown to predispose people to higher risk of cardiovascular disease. , A form of validity that, together with discriminant validity, provides evidence of construct validity. Such a metric should also provide a test of the statistical significance of the match between observed and expected correlations, and provide confidence intervals for that match, taking into account the like-lihood that some of the validating variables may not be indepen-dent of one another. As evidence of convergent/ concurrent validity, Buss and Perry (1992) reported positive correlations between the BPAQ subscales and various trait measures as follows: BPAQ Physical Aggression correlated .20 (men) with Activity, .28 with Impulsiveness, .28 with Assertiveness, and .36 with Competitiveness. There are two forms of criterion-related validity: predictive validity and concurrent validity. Concurrent validity differs from convergent validity in that it focuses on the power of the focal test to predict outcomes on another test or some outcome variable. share. Convergent validity takes two measures that are supposed to be measuring the same construct and shows that they are related. Convergent validity is one of the topics related to construct validity (Gregory, 2007). This research was reviewed and approved by the Human Investigation Committee of Memorial University of Newfoundland, Canada. This is because lifestyle and health status are not measurements of the same construct but rather related constructs. and 0.665, resp. save. This is expected … all SLIQ components are scored such that a higher number means a better lifestyle (in this case lower stress). Similarly, in a health research setting the issue of participant burden has to be considered and long detailed questionnaires should be avoided. Finally, the study population was somewhat skewed towards women (65%) and older age group (mean age 65 years). They compared the response to eight questions on diet, activity, smoking, alcohol, and BMI to a person’s likelihood of dying. Convergent validity is a subcategory of construct validity. have been shown to predict mortality, why not we use them rather than the SLIQ for assessing lifestyle. In reality, even measured variables that are designed to measure different conceptual variables will often . Showing that an IQ test is valid by comparing the results of it to academic results and seeing a positive correlation. Divergent Validity – When two opposite questions reveal opposite results. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. I’ve never heard of “translation” validity before, but I needed a good name to summarize what both face and content validity are getting at, and that one seemed sensible. One hundred and ninety-three individuals from St. John’s, Newfoundland, and Labrador, Canada completed the SLIQ and r… One hundred and ninety-three individuals from St. John’s, Newfoundland, and Labrador, Canada completed the SLIQ and reference standards for diet, exercise, stress, and alcohol consumption. Concurrent validity refers to whether a test’s scores actually evaluate the test’s questions. Concurrent validity is a type of evidence that can be gathered to defend the use of a test for predicting other outcomes. [, Self-assessed health on the SF36 (Question  1), S. S. Bassuk and J. E.

Using an alpha of 0.05 and a beta of 0.2, we calculated that 153 participants would be needed to make sure that a correlation of 0.2 or more was statistically different from a correlation of zero. Its psychometrics has been assessed in all age groups, genders, and many races and countries. As far as I could see they both increase the validity of research by showing that related variables or constructs are related to their research. In the figure below, we see four measures (each is an item on a scale) that all purport to reflect the construct of self esteem. The details of the correlations are presented in Table 2 and Figures 1, 2, 3, 4, 5, and 6. For concurrent validity, we hoped to achieve correlation coefficients of 0.4 or higher and ideally larger than 0.6. The concurrent validities between the test and other measures of the same domain are correlational measures of convergent validity. On the bottom part of the figure (Observation) w… Supplementary Figure 2: Show the 12 questions on the SLIQ and how raw and category scores are calculated for each of the five component scores and the Overall SLIQ scores. Comparison of SLIQ scores in the three category levels of unhealthy, intermediate, and healthy using ANOVA. Lifestyle issues including physical activity, diet, smoking, alcohol consumption, and self-reported stress have all been shown to predispose people to higher risk of cardiovascular disease. Correlations between scores on the SLIQ and the reference standards were the SLIQ versus DHQ ( Concurrent vs. Predictive Validity. Concurrent validity is a type of evidence that can be gathered to defend the use of a test for predicting other outcomes. A French version is also available, but none of the psychometric testing has been carried out in French. Lifestyle issues including physical activity [1, 2], diet [3–5], smoking [6], alcohol consumption [7], and self-reported stress [8] have all been shown to predispose people to higher risk of cardiovascular disease [9]. There was still a need to further assess the validity of the individual components. Subsequently two further blocks of 100 people per age group were contacted until we had sufficient sample size.
