differentiate between concurrent validity and predictive validity

While having high concurrent validity is one important aspect of quality for an assessment instrument, perhaps the most important characteristic for PA questionnaires used in clinical is their validity to predict a patient’s risk for unwanted health outcomes. If the outcome of interest occurs some time in the future, then predictive validity is the correct form of criterion validity evidence. However, the large absolute misclassification (median bias 185 min per day, 5th to 95th perc: −467 to 119 min per day) makes the usefulness in an individual case problematic. Differences between concurrent and predictive validity studies o Concurrent from PHYS 204 at University of Louisiana, Monroe The difference in results may stem from the difference in design or outcome. The descriptive data is presented as proportions or median and 25th–75th percentile (Q1–Q3). Van Zaalen, Y. Mens, E.J.M. According to the results of the present study, using open alternatives may be a barrier for the respondent to accurately judge the actual sedentary time. 2014;19:22. doi:10.1186/2047-783X-19-22. Criterion validity is split into two different types of outcomes: Predictive validity and concurrent validity.

Lindwall M, Gerber M, Jonsdottir IH, Borjesson M, Ahlborg Jr G. The relationships of change in physical activity with change in depression, anxiety, and burnout: a longitudinal study of Swedish healthcare workers. For example, in a normal weight woman, this equals to an oxygen consumption of approximately 0.6–0.75 l per minute or a caloric expenditure of 3–4 kcal per minute. Key Differences Between Validity and Reliability. Matthews CE, Chen KY, Freedson PS, Buchowski MS, Beech BM, Pate RR, et al. Table 1 shows participant characteristics. 2003;35(8):1381–95. The above correlations indicate that validities between concurrent and predictive validity samples are different, with predictive validity coefficients usually (but not always) being lower than concurrent coefficients. Parallel forms reliability. Such activities may therefore pass unnoticed and is not consciously associated with the term “moderate” when responding to a PA question, leading to en underestimation in some participants. How Does One Differentiate Between Concurrent And Predictive Validity? A 20-country comparison using the International Physical Activity Questionnaire (IPAQ). Reported sedentary time was lower than accelerometer derived. Public Health Nutr. Article  The predictive ability of two models, a reduced/parsimonious model including the BBS only and a second model including both the BBS and DGI, were compared using the adjusted coefficient of determinations. http://www.folkhalsomyndigheten.se/documents/statistik-uppfoljning/enkater-undersokningar/nationella-folkhalsoenkaten/frageformular/formular-nationella-folkhalsoenkaten-2012.pdf.

Neilson HK, Robson PJ, Friedenreich CM, Csizmadi I. Estimating activity energy expenditure: how valid are physical activity questionnaires? In many studies, other risk factors (e.g. Importantly, a clear dose–response relation was found for the PHAS-question, with falling ORs in more active strata. Deckers, S.R.J.M. doi:10.2165/11531930-000000000-00000. Örjan Ekblom. doi:10.1177/2047487312437063. Concurrent validity measures the test against a benchmark test and high correlation indicates that the test has strong criterion validity. Predictive validity is a measure of how well a test predicts abilities. External validity is about generalization: To what extent can an effect in research, be generalized to populations, settings, treatment variables, and measurement variables?External validity is usually split into two distinct types, population validity and ecological validity and they are both essential elements in judging the strength of an experimental design. Just to keep you on your toes, there are two main types: concurrent validity and predictive validity. Differentiate between concurrent, predictive, convergent, and discriminant validity. Int J Behav Nutr Phys Act. For each self-report, reference value was set as the lowest quartile, i.e. The line of identity is plotted in the figure. Concurrent validity was assessed using correlation analysis or Spearman’s rho if appropriate, to examine for potential relationships between self-reported (categories and minutes per week, respectively) and accelerometer derived data. It is therefore concerning, that the studied questions poorly predicted fulfilment of current PA recommendations. Research in Developmental Disabilities, Vol. Concurrent validity’s main use is to find tests that can substitute other … Springer Nature. Quantity and quality of exercise for developing and maintaining cardiorespiratory, musculoskeletal, and neuromotor fitness in apparently healthy adults: guidance for prescribing exercise. GB was responsible for study design. Correspondence to A sample of current employees is used to ascertain the predictor- criterion relationship, and then the resulting regression may be applied by obtain­ing predictor scores on the remaining job holders. To investigate the predictive and concurrent validity of magnetic resonance imaging (MRI)-based cartilage thickness change between baseline (BL) and year-two (Y2) follow-up (predictive validity) and between Y2 and Y4 follow-up (concurrent validity) for symptomatic and radiographic knee osteoarthritis (OA) progression during Y2→Y4. 2001;285(19):2486–97. © 2021 BioMed Central Ltd unless otherwise stated. 2012;19(5):1005–33. These two concepts are very closely related, although their meanings are different. Vanhees L, Geladas N, Hansen D, Kouidi E, Niebauer J, Reiner Z, et al. Discuss the difference between concurrent validity and predictive validity and describe a situation in which you would use an instrument that has concurrent validity and predictive validity. The concurrent and predictive validity of the Dutch version of the Communicative Development Inventory in children with Down Syndrome for the assessment of expressive vocabulary in verbal and signed modalities. J Intern Med. doi:10.1093/aje/kwm390. The answers from the open questions predicted low intensity activities better, as shown in Table 2. If the outcome occurs at the same time, then concurrent validity is correct. Our results thus imply that a fixed answer category seems more valid for identifying individuals at risk for MetS, compared to open ones. The ability of the studied questions to correctly identify participants meeting PA recommendations was low. PubMed  The agreement between self-reports and objectively assessed PA was low to moderate (Table 2). 2006;9(2):258–65. The rather low concurrent validity of clinically used PA questionnaires, found in the present study is of great importance, because such questions are routinely used for PA assessment in regular health care. The low to moderate correlations between the questions (PHAS, SGPALS and MVPA) and objectively assessed MVPA, are in line with earlier studies [3, 4]. As indicated visually in Figs. 1 and 2, weak relationships were present, between reported sedentary time and objectively measured time spent being sedentary as well as time spent in MVPA. include concurrent validity, construct validity, content validity, convergent validity, criterion validity, discriminant validity, divergent validity, face validity, and predictive validity.

Predictive validity is similar to concurrent validity in the way it is measured, by correlating a test value and some criterion measure. In a research design, especially in a quantitative research, reliability and validity are highly important. doi:10.1249/MSS.0b013e318213fefb. Saltin B, Grimby G. Physiological analysis of middle-aged and old former athletes. As methods with low concurrent validity will often underestimate the effect in comparisons to other risk factors, due to dilution, the effects of PA may be underestimated. Experts are waiting 24/7 to provide step-by-step solutions in as fast as 30 minutes!*. From the self-reports, 10.5 % of the participants reported no sedentary time, while the lowest accelerometer derived average time spent in sedentary activity was 162 min per day. Similar results, as those presented by Katzmarzyk have earlier been shown by Matthews and colleagues [25]. The two types of criterion-related validity are concurrent validity and predictive validity. Criterion validity is a type of evidence where a survey instrument can predict for existing outcomes. Conversely, the reported time spent in MVPA was higher than the values obtained by accelerometry (i.e. Further concurrent validity evidence for selected subscales was provided through moderate associations with students’engagement in social activities and their self-reported use of psychological services provided on campus. et al. Differences between genders were tested with Chi-square and Mann–Whitney U tests. Among the open answer option questions, only MVPA showed strong correlation to MetS, with the third strata in the WALK-question showing border line significance. a. The highest AUC for the second interpretation was found for the WALK question (0.70: 95 % CI: 0.64 to 0.76). The differences between the two are very subtle. In spite of this, the predictive validity of the questions with fixed answering alternatives (PHAS and SGPALS) was moderate to high for predicting MetS, although the highest quartile for SGPALS did not differ from the lowest (possibly due to a low number of values). This may be is easily accomplished during many daily activities (such as transport or household chores), rather than structured exercise. Q: Eden obtains a mark of 67 on her final year exam. Circulation. This type of validity is established when the test and the criterion are administered at about the same time. As the name suggests, concurrent validity relies upon tests that took place at the same time. While reliability deals with consistency of the measure, validity deals with accuracy of the measure. Therefore, the more naturalistic approach was chosen. For PHAS and SGPALS, these strata were the four response alternatives and for walking (WALK), MVPA and sedentary time, sex-specific quartiles were used. Internal validity etc. doi:10.1249/01.MSS.0000078924.61453.FB. only those who provided data from all questions) the results were the same, with regard to significances and ranking between questionnaires. Thus, the concurrent validity of the questionnaires was found to be low. Question: How Does One Differentiate Between Concurrent And Predictive Validity?

What are convergent and divergent assessment useful for? Craig CL, Marshall AL, Sjostrom M, Bauman AE, Booth ML, Ainsworth BE, et al. Predictive validity refers to the ability of the instrument to predict some other variable, usually in the future. In the light of the excessive mismatch in our present data and others [26], both absolute levels and geographical variations in the Eurobarometer findings, may therefore be questioned, because of the potential for misclassification of PA when using self-report measures. American College of Sports Medicine position stand. Sweden PHao. 2012;9:103. doi:10.1186/1479-5868-9-103. The standard ... *Response times vary by subject and question complexity. Men reported a higher energy intake, compared to women. None of the studied questions met the criterions for level 1 or level 2 evidence (r >0.5 using accelerometer as reference method) according to van Poppel and colleagues [20] or standard for measurement properties of PA questionnaires as stated in the Quality Assessment of Physical Activity Questionnaire (r >0.5 for TPA, MPA or VPA, or r >0.7 for WALK) [21].
