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. In the case of discriminant validity, you could show that there is no correlation at all. 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. ", "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. Predictive Validity the extent that a measure predicts another measure regression analysis, discriminant analysis Concurrent Validity the extent that a measure simultaneously relates to another measure that it is supposed to relate correlation analysis Convergent Validity … To increase the accuracy of measurement, we often have to use long and detailed questionnaires or similar meticulous processes. 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. The SRRS is scored such that a higher number means higher stress. As mentioned in the results, the correlation for SLIQ stress score versus the SRRS stress score is negative. 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. In reality, even measured variables that are designed to measure different conceptual variables will often . , Convergent validity refers to the observation of strong correlations between two tests that are assumed to measure the same construct. 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. However, what is preferred is a measure that is short and easy, especially in a clinical setting where providers are busy and patients may be ill. 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. Concurrent validity. , It is a validated instrument which scores 43 life events from 12 to 100. Ideally, this means testing the subjects at exactly the same moment, but some approximation is acceptable. Concurrent validity focuses on the extent to which scores on a new measure are related to scores from a criterion measure administered at the same time, whereas predictive validity uses the scores from the new measure to predict performance on a criterion measure administered at a later time. Discriminant validity (or divergent validity) tests that constructs that should have no … Is there anyone that could explain it and provide some examples?? 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. Two methods are often applied to test convergent validity. Concurrent validity is a type of evidence that can be gathered to defend the use of a test for predicting other outcomes. 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. We expected a correlation coefficient in the range of 0.2 to 0.4. Convergent validity for the LEAS-C as an objective assessment of emotion complexity in children was demonstrated by a significant association with an emotion comprehension task and two verbal tasks. Using a pedometer for three days has been shown to be highly correlated with the level of physical activity [20, 21]. face validity, content validity, predictive validity, concurrent validity, convergent validity, discriminant validity (are you measuring what you are intending to measure) face validity. Copyright © 2013 Marshall Godwin et al. Convergent validity states that tests having the same or similar constructs should be highly correlated. ), SLIQ versus alcohol consumption ( We sent letters to 900 people in order to recruit 193 consenting patients who completed all the questionnaires. Concurrent validity is one of the two types of criterion-related validity. [19]. 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. The SF36 is a health status measurement tool used in over 4000 published studies worldwide. We are committed to sharing findings related to COVID-19 as quickly as possible. Concurrent Validity vs Convergent Validity. If the scores for each employee on both tests are closely related, then the new scale is said to have high concurrent validity." More details on the SLIQ are in Section 2. 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. A form of validity that, together with discriminant validity, provides evidence of construct validity. There was still a need to further assess the validity of the individual components. Others divide the correlation coefficient into three categories where an Tests of data quality, scaling assumptions, and reliability across diverse patient groups,”, W. M. Hopman, T. Towheed, T. Anastassiades et al., “Canadian normative data for the SF-36 health survey,”, C. A. Spencer, K. Jamrozik, P. E. Norman, and M. Lawrence-Brown, “A simple lifestyle score predicts survival in healthy elderly men,”, C. Tudor-Locke, L. Burkett, J. P. Reis, B. E. Ainsworth, C. A. Macera, and D. K. Wilson, “How many days of pedometer monitoring predict weekly physical activity in adults?”, P. L. Schneider, S. E. Crouter, and D. R. Bassett, “Pedometer measures of free-living physical activity: comparison of 13 models,”, J. F. Hemphill, “Interpreting the magnitudes of correlations coefficients,”. Convergent validity is measured by comparing the instrument in question with another instrument that measures a related, but different, construct. It typically is estimated by correlating scores on a new measure with scores from an accepted criterion measure. A French version is also available, but none of the psychometric testing has been carried out in French. Is there anyone that could explain it and provide some examples?? Finally, we compare the overall SLIQ score with the score on the eight-question risk assessment developed by Spencer et al. To establish convergent validity, you need to show that measures that should be related are in reality related. CONVERGENT, DISCRIMINANT, CONCURRENT VALIDITY AND SF-6D was calculated with and without the weights which rep- RELIABILITY OF THE EQ-5D(CHILD): RESULTS resent the preferences of population about different health status. ), SLIQ versus SRRS ( 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. To demonstrate convergent validity, the authors also developed a communal overclaiming measure based on the technique previously developed to measure agentic self-enhancement (Paulhus, Harms, Bruce, & Lysy, 2003). include concurrent validity, construct validity, content validity, convergent validity, criterion validity, discriminant validity, divergent validity, face validity, and predictive validity. Showing that an IQ test is valid by comparing the results of it to academic results and seeing a positive correlation. Both types of validity are a requirement for excellent construct validity. Convergent validity is measured by comparing the instrument in question with another instrument that measures a related, but different, construct. Construct Validity: Convergent vs. Discriminant. The criteria are measuring instruments that the … Criterion validity evaluates how closely the results of your test correspond to the … 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. Sorry if this isn't the right place to post this but I can't think of any other subreddit . The only Convergent/ Concurrent validity findings available for the ILP must be derived from regression analyses conducted by Pulford and Sohal (2006). The Simple Lifestyle Indicator Questionnaire (SLIQ) remains the only short, easy-to-use instrument available for measuring cardiovascular lifestyle as a single construct. Testing for this type of validity requires that you essentially ask your sample similar questions that are designed to provide you with expected answers. Like I'm reading up definitions online and they're saying this for concurrent validity: "Concurrent validity is the extent to which performance on a measurement is related to current performance on a similar, previously established measurement. The SRRS collects information on stressful life events in the past year. This is expected … all SLIQ components are scored such that a higher number means a better lifestyle (in this case lower stress). 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. If the scores for each employee on both tests are closely related, then the new scale is said to have high concurrent validity. K Bannigan and R Watson 3238 2009 Blackwell Publishing Ltd, Journal of Clinical Nursing, 18, 3237–3243. Convergent Validity is a sub-type of construct validity. An This type of validity goes hand-in-hand with discriminant validity to create perfect construct validity. Convergent validity tests that constructs that are expected to be related are, in fact, related. The SLIQ diet and alcohol components correlate well with diet and alcohol as assessed by DHQ ( The higher the score the higher the likelihood of experiencing stress [13, 14]. Assessments of the SLIQ sensitivity to change and its predictive validity are both underway. It was developed as a short and simple health measurement scale [10]. People deal with stress differently, and the person’s assessment of their own feelings of stress may be more important. ex. Similarly, in a health research setting the issue of participant burden has to be considered and long detailed questionnaires should be avoided. The SLIQ has 12 questions; three on diet, three on physical activity, three on alcohol consumption, two on smoking, and one on stress—see Supplementary Figure 1 (see Supplementary Materials available online at http://dx.doi.org/10.5402/2013/529645). None of the differences in convergent and concurrent validity between the BBS and DGI were significant. 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. 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. Convergent/Concurrent. This is despite use of the most conservative estimate—the lower bound of the 95% confidence interval for the Pearson Coefficient. We used ANOVA to determine the mean and standard deviations and 95% CI for these groups. Convergent validity video that explains the definition in a dynamic and interactive way. For concurrent validity, we hoped to achieve correlation coefficients of 0.4 or higher and ideally larger than 0.6. It is a parameter used in sociology, psychology, and other psychometric or behavioral sciences. share. The SLIQ is sufficiently valid when compared to reference standards to be useful as a brief assessment of an individual’s cardiovascular lifestyle in research and clinical settings. The scoring template is shown in SupplementaryFigure2. Second, a validity diagonal value should be higher than the val-ues lying in its column and row in the heterotrait-heteromethod triangles. One hundred and ninety-three adults completed all the questionnaires allowing correlational statistics to be completed. The population was distributed through the socioeconomic spectrum but was financially better and more educated than the general population. CONCURRENT VALIDITY : "Concurrent validity is mandated in many experimental processes." For example, if scores on a specific form a aggressiveness test are similar to people's scores on other aggressiveness tests, then convergent validity is high (there is a positively correlation between the scores from similar tests of aggressiveness).". Also, as anticipated, the LEAS-C was more strongly associated with emotion comprehension than emotion expression (Bajgar et al., 2005). One reason is that Spencer included BMI which is not a lifestyle but rather a consequence of lifestyle; moreover, there have been no psychometrics conducted on the eight questions unlike the SLIQ which has a developing literature. The DHQ is a long and detailed questionnaire and is probably as good as any we could have chosen. Revised on June 19, 2020. Convergent validity is assessed by calculating AVEs, i.e., Average Variance Extracted for each construct and should be > .50. Convergence of independent methods: the distinction between reliability and validity. Scatter plots with best-fit lines are also presented for each component. Review articles are excluded from this waiver policy. Each participant provided basic demographic data and completed the SLIQ instrument, a detailed Diet History Questionnaire (DHQ) [11, 12], the Social Readjustment Rating Scale (SRRS) [13, 14], Question 1 on the SF36 Health Status Questionnaire [15–18], and a survey of eight questions on cardiovascular risk proposed by Spencer et al. The DHQ collects detailed information on type and quantity of different foods (vegetables, fruit, grains, meat, fish, dairy products, etc.) Concurrent vs. Predictive Validity. • criterion validity, (which includes concurrent and predic-tive validity); • construct validity (which includes convergent, divergent, factorial and discriminant validity) (Lynn 1986). Cost was one issue for us in this regard. Like to me the examples given just seem so similar, I have no clue how to differentiate them because in both examples they're comparing scores between two tests. Subsequently two further blocks of 100 people per age group were contacted until we had sufficient sample size. Convergent validity video that explains the definition in a dynamic and interactive way. On the bottom part of the figure (Observation) w… E.G. Convergent validity is a subcategory of construct validity. The scoring template is shown in Supplementary Figure 2. The chosen reference standard, and whether it is the most appropriate, is always an issue with validity studies. 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. Initial psychometric testing of its reliability, internal validity, and basic external validity testing was published in 2008 [10]. Contrasted groups. Convergent Validity. 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. 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. Convergent validity takes two measures that are supposed to be measuring the same construct and shows that they are related. We theorize that all four items reflect the idea of self esteem (this is why I labeled the top part of the figure Theory). of zero indicates no correlation and an It has been suggested that we should have used an accelerometer to measure actual physical activity rather than a pedometer. They compared the response to eight questions on diet, activity, smoking, alcohol, and BMI to a person’s likelihood of dying. Correlations between scores on the SLIQ and the reference standards were the SLIQ versus DHQ ( I'm studying for a psych research final right now, and I've been trying to understand and differentiate Concurrent Validity and Convergent Validity! Contrasted groups. Discriminant validity occurs where constructs that are expected not to relate do not, such that it is possible to discriminate between these constructs. Nilsson, and G. Berglund, “Chronic psychosocial stress predicts long-term cardiovascular morbidity and mortality in middle-aged men,”, D. Mozaffarian, P. W. F. Wilson, and W. B. Kannel, “Beyond established and novel risk factors lifestyle risk factors for cardiovascular disease,”, M. Godwin, S. Streight, E. Dyachuk et al., “Testing the simple lifestyle indicator questionnaire: initial psychometric study,”, T. H. Holmes and R. H. Rahe, “The social readjustment rating scale,”, M. Horowitz, C. Schaefer, and D. Hiroto, “Life event questionnaires for measuring presumptive stress,”, C. A. McHorney, J. E. Ware Jr., and A. E. Raczek, “The MOS 36-Item Short-Form Health Survey (SF-36): II. hide. We also report on convergent validity of the whole instrument and compare the overall SLIQ scores to scores on a similar series of questions that have been correlated with cardiovascular morbidity and morbidity. Convergent validity, a parameter often used in sociology, psychology, and other behavioral sciences, refers to the degree to which two measures of constructs that theoretically should be related, are in fact related. It also collects detailed information on alcohol consumption [11, 12]. In quantitative research, you have to consider the reliability and validity of your methods and measurements.. Validity tells you how accurately a method measures something. 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 is to correlate the scores between two assessment tools or tools’ sub-domains that are considered to measure the same construct. Press J to jump to the feed. Convergent Validity – When two similar questions reveal the same result. Convergent Validity. 2.0 for convergent validity, look at factor loading. Construct validity means that a test designed to measure a particular construct (i.e. 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. Details of education, marital status, income, and BMI are shown in Table 1. Convergent validity, along with discriminant validity, is a subtype of construct validity. Convergent validity applies greatly in medicine, education, psychology, and social science. Criterion-related validity is concerned with the relationship between individuals’ performance on two measures tapping the same construct. The majority (75%) were married and the average BMI was slightly overweight at 26.5. In order to estimate this type of validity, test-makers administer the test and correlate it with the criteria. as a level of strong correlation. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. This is because lifestyle and health status are not measurements of the same construct but rather related constructs. 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. This re-quirement is evidence of convergent validity. Convergent validity, a parameter often used in sociology, psychology, and other behavioral sciences, refers to the degree to which two measures of constructs that theoretically should be related, are in fact related. The additional variation in 6MWT explained by the DGI when added to a model with the BBS was 7.78% (95% CI: 0.6%, 15%). Similarly, its correlation with the eight-question scale, which themselves have been shown to predict mortality, increases the SLIQ validity. 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. 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. I'm studying for a psych research final right now, and I've been trying to understand and differentiate Concurrent Validity and Convergent Validity! 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. Sign up here as a reviewer to help fast-track new submissions. As the name suggests, concurrent validity relies upon tests that took place at the same time. Opinion on how a given level of correlation between 0 and 1 should be interpreted varies in the literature. Convergent validity states that tests having the same or similar constructs should be highly correlated. The correlation with stressful life events is negative because on the SLIQ a higher score for stress means less stress whereas on the SRSS a higher count indicates more stress. ANOVA was conducted to determine if the three categories, unhealthy, intermediate, and healthy, were separately distinguishable populations for each component and for the overall SLIQ score. 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. If they don’t, the questions might not be valid. It has also been suggested that since the eight questions used by Spencer et al. 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.
