Concurrent validity between the CBM and the other balance and mobility tests was assessed using the Spearman’s rank correlation coefficient (ρ) since the results of the 8-level balance scale (p < .001), errors during 3MTW (p < .001), and gait speed test (p < .05) were not normally distributed according to the Kolmogorov-Smirnov test. Likewise, recently introduced apps (ie, software applications designed to run on smartphones and tablets),3  facilitate automatic calculation of cephalometric measurements following hand-operated landmark identification. 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 percentage of patients for which a clinically relevant difference was found when compared with the reference values ranged from 2% for ANB in the case of OneCeph vs Viewbox and for SNB in the case of CephNinja vs Viewbox, to 56% and 54% for the interincisal angle for OneCeph and CephNinja, respectively (Table 2). 2.8.1. 26th Feb, 2015. The second link includes a video on how to test these two types of validity in SPSS. The ICC values for intratool reliability ranged from .647 to .993 (Table 3). There are two kinds of validity that can be gauged statistically. startxref Concurrent validity was; evaluated by computing the correlation between the WHODAS-2 score and injury severity scale. Smartphone apps may have a great potential in supplementing traditional cephalometric analysis. +y5:�� To assess the diagnostic accuracy of two smartphone cephalometric analysis apps compared with Viewbox software. 2 Recommendations. 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. Results. SPSS 17 was used for data analysis. Concurrent validity is a concept commonly used in psychology, education, and social science. Not Found. Sections. When measuring U1 to NA (mm) with OneCeph and when measuring L1 to NB (mm) with either OneCeph or CephNinja, measurements were systematically lower compared with those obtained from Viewbox. 0000002192 00000 n Concurrent validity was assessed by comparing results between AIMS and the Peabody Developmental Motor Scale-2 (PDMS-2). The sample size, extent of the repeated measurements, robustness of statistical methods, and masking of patient identifiers applied in this investigation are deemed more advantageous compared with similar research.12–14  As in the study of Goracci and Ferrari,12  the long experience in cephalometrics and on-screen digitization of the examiner who performed all tracings might have also contributed to the more favorable results, since it is well-recognized that the operator's experience in landmark identification affects cephalometric measurements.26,27  The selected cephalometric landmarks need to be considered when interpreting the results of such research. Providing orthodontic expertise to general dental practitioners serving disadvantaged children via teleconferencing has been proven to be successful at improving the accurate diagnoses of malocclusions and appropriate referrals.30–32. 0000001426 00000 n Q��Pf%�����s��[�O�����Yd�L. Concurrent Validity: Concurrent Validity correlating the test scores with another set of criterion scores. The ICC values for intratool reliability ranged from .647–.993. Further development of smartphone apps for cephalometrics may assist specialty training and interprofessional communication. The criteria are measuring instruments that the test-makers previously evaluated.

Seven angular and two linear measurements originating from the Steiner cephalometric analysis,20  the prevailing cephalometric analysis in orthodontic practices,2  all available in the analysis protocols of Viewbox and both apps, were selected for the tracing procedures, namely, the angles SNA, SNB, ANB, SN to GoGn, upper incisor to NA (U1 to NA), lower incisor to NB (L1 to NB), interincisal angle, and the linear distances of the most prominent points of the labial surfaces of the upper and lower incisors perpendicular to NA and NB, respectively (Figure 1B). If both tests produce similar results, then the new test is said to have concurrent validity. Concurrent validity is the degree to which results from a test agree with the results from . 0000002342 00000 n To further generalize the current findings, it would be useful to run studies on the feasibility of app-based cephalometric analysis, namely, the time required to complete cephalometric analysis using apps compared with computer-aided software. A comparison of the effects of Forsus appliances with and without temporary anchorage devices for skeletal Class II malocclusion. The lower border of the 95% CI of SN to GoGn was below .7 and those of U1 to NA (mm) and L1 to NB (mm) were below .9. 5. Pretreatment digital lateral cephalograms of 50 consecutive orthodontic patients attending a private practice (Dental Clinics Zwolle, Zwolle, the Netherlands) between August and October 2017 were retrospectively collected for the purposes of the study. Statistical analyses were performed using SPSS version 24.0 (SPSS Inc., Chicago, Illinois, USA). The test scores are truly useful if they can provide a basis for precise prediction of some criteria. For OneCeph, ANB, SN to GoGn, U1 to NA, L1 to NB, and L1 to NB (mm) presented with ICC and/or lower border of the 95% CI below the accepted cutoffs (Table 3). Jeromy Anglim. Therefore, the aim of this study was to assess the concurrent validity and reliability of cephalometric measurements generated by two popular, free apps, CephNinja (version 1.0, Naveen Madan, Bothell, Wash) and OneCeph (version beta 1.1, NXS, Hyderabad, Telangana, India), compared with Viewbox (Viewbox 4, dHAL Software, Kifissia, Greece) as the reference standard. Data analysis was performed using SPSS 24.0 software. Convergent and discriminant validity are both considered subcategories or subtypes of construct validity. In this way, training in cephalometrics can take place away from traditional learning locations. Two methods are often applied to test convergent validity. To eliminate interobserver variability and to focus on the intertool variability, a single examiner (Dr Livas) traced the radiographs randomly first using Viewbox, then OneCeph, and finally CephNinja. 0000003895 00000 n 38 to. Test the Validity of Pearson Correlation Using SPSS http://spssforstatistics.com/test-the-validity-of-pearson-correlation-using-spss/ Patient identifiers (ie, name, age, gender, and date of examination) were cropped out of the original lateral cephalograms to maintain patient privacy. Cronbach alpha reliabilities range from 0.49 to 0.87, and concurrent validity as reported in per cent agreement ranging from 75 to 91 per cent (Squires et al., 1995). share | cite | improve this question | follow | edited Jun 6 '13 at 11:56. Validity and reliability of the BOT2 have been examined in healthy children [9,14,15] but never in CP [16]. In addition, the ICC and 95% CI were calculated. trailer The data were analysed by using statistical package for social sciences, version-20 (SPSS ® 20.0 IBM ®). Table 1 shows the means and standard deviations (SD) of all cephalometric measurements obtained with Viewbox and apps at both sessions. It refers to the extent to which the results of a particular test … The ICCs and/or lower border of the 95% CI of U1 to NB (mm) and L1 to NA (mm) were below .7 and of ANB as well as SN to GoGn were below .9. Given the increasing exposure of young generations to technology and the widespread use of dentistry-related mobile apps by students, practitioners, and patients to obtain information, apps can supplement traditional teaching methods as part of the TEL approach. Exploring outliers showed that they were not related to one specific cephalogram/patient. 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. Search form. The highest total score possible is 300. Criterion validity describes how a test effectively estimates an examinee’s performance on some outcome measure(s). Although such a decision might be initially considered a limitation, it was actually an asset of the study design. A concurrent validity study design was conducted in a Bachelor level nursing degree programme located in Italy. 0000001622 00000 n Concurrent validity of OneCeph and CephNinja apps (ie, the degree to which an outcome measure measures the construct it purports to measure) was estimated by comparing the first session measurements of each app to the reference standard (ie, Viewbox) using repeated-measures analysis of variance. 85. Strictly looking at the number of app measurements below the acceptable cutoffs for research and clinical practice, OneCeph might be considered a slightly more valid alternative to Viewbox than CephNinja. The scale also demonstrated good predictive validity in patients recovering from MI with individual items being related to mental and physical functioning at 3 months' follow-up, cardiac rehabilitation class attendance, and speed of return to work. other measures of the same or similar constructs. Convergent validity states that tests having the same or similar constructs should be highly correlated. xڌSGOA~�kvlǀ ��Tcz��M�`z �{3x]0L�D���M.�:"ʙ?�׈�r�1� �(Oo�������� 2�@| At the time the study was conducted, the examiner had 15 years of clinical experience in orthodontics and more than 10 years of experience using Viewbox and has been previously calibrated.16–19  Prior to the study, a 3-hour training for each app was carried out to allow the examiner to master the tracing method. On the other hand, fewer CephNinja measurements indicated significant differences in comparison with Viewbox, with SN to GoGn and L1 to NB (mm) being significantly differently measured by either app. Conclusions. Future research should focus on assessing the performance of app versions installed on smartphones vs tablets. Convergent validity is one of the topics related to construct validity (Gregory, 2007). This type of validity is similar to predictive validity. As the vast majority of smartphones are not equipped with a stylus, identification of landmarks was performed directly on the touchscreen by a finger to represent mainstream use. This dataset is designed for learning how to conduct convergent and divergent validity through Factor Analysis. Hard tissue, Accuracy of digital and analogue cephalometric measurements assessed with the sandwich technique, Toygar Memikoglu TU. The ICC of the comparison between OneCeph and Viewbox ranged from .903 to .983 (Table 2). As the name suggests, concurrent validity relies upon tests that took place at the same time. How can this be done in SPSS? Hypothetically, and regardless of the app design that allows image magnification and adjusting brightness/contrast, the larger viewing screen of tablets and the use of a stylus to digitize the landmarks may be more operator friendly compared with smartphones. Confirmatory factor analysis. Reliability (ie, the degree to which the measurement is free from measurement error) was determined using paired t-test and the limits of agreement on measurements acquired by the three programs (session 1 vs session 2). Both convergent and concurrent validity are ways of assessing construct validity by examining the strength of the relationship between the scores from two different measurement procedures. Results. Intraclass correlation coefficients (ICCs; two-way mixed-effects model, single measures, absolute agreement) and the 95% confidence intervals (CIs) were calculated. Convergent/Concurrent. Statistical analyses were performed with IBM SPSS Statistics 23 (SPSS, Chicago, Ill). Certification of mobile apps for health care, The ownership and clinical use of smartphones by doctors and nurses in the UK: a multicentre survey study. xref Cite. Both convergent and concurrent validity are ways of assessing construct validity by examining the strength of the relationship between the scores from two different measurement procedures. OneCeph is highly valid when compared with Viewbox as a gold standard, while CephNinja is the most reliable one. Overall, both cephalometric analysis apps performed satisfactorily, suggesting the potential use of easy-to-reach digital technology to make cephalometrics more readily accessible. All nursing students attending the first, second or third year (n = 428) were the target sample. Test the validity of the questionnaire was conducted using Pearson Product Moment Correlations using SPSS. In the case of multiple observers, interindividual differences in competence in using mobile apps as well as in cephalometric experience would have influenced the results. Pretreatment digital lateral cephalograms of 50 consecutive orthodontic patients (20 males, 30 females; mean age, 19.1 years; SD, 11.7) were traced twice using two apps (ie, CephNinja and OneCeph), with Viewbox used as the gold standard computer software program. In case of significant deviations from sphericity, a Greenhouse-Geisser correction was applied. For instance, Item 1 might be the statement “I feel good about myself” rated using a 1-to-5 Likert-type response format. The factor loadings of the 20 items on the 3 subscales ranged from. Concurrent validity’s main use is to find tests that can substitute other … http://www.theaudiopedia.com What is CONCURRENT VALIDITY? In total, lateral cephalograms of 20 males and 30 females (mean age, 19.1 years; SD, 11.7) were traced. Pearson correlational analysis was used to establish concurrent validity. 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.

Participation in life activities was negatively associated with severity of illness (r = -.24, p = .000). U1 to NA (mm) in OneCeph was significantly different compared with Viewbox (Table 2). Not Found. You determine this by correlating your classifications (x) with classifications or scores from a criterion measure (y). This video demonstrates how to conduct and interpret a Discriminant Analysis (Discriminant Function Analysis) in SPSS including a review of the assumptions. Test-retest reliability of the FTST and ST is excellent and concurrent validity is strong for older adults with unilateral primary THA. Accordingly, the validity and reliability analysis with more active patients may be brought up again, especially for SEM and MDC values in order to obtain more detailed results. Opener. The first two authors contributed equally to this work. The concurrent validity of classifications is examined when you are interested in the extent to which classifications (master/non master) are correct. This video covers material from Research Methods for the Behavioral Sciences (4th edition) by Gravetter and Forzano. The outcome measure, called a criterion, is the main variable of interest in the analysis. Seven angular and two linear measurements, originally derived from Steiner cephalometric analysis, were performed. These are concurrent validity and predictive validity..

We theorize that all four items reflect the idea of self esteem (this is why I labeled the top part of the figure Theory). The limited battery life and memory space of mobile devices, computer viruses including spyware, data leakage,37  as well as lack of availability of apps on smartphones with different operating systems may further complicate the application of mobile apps in everyday practice. a Descriptive statistics were calculated for TAI and TAI-Q total, ... Table 2 shows concurrent validity, intrarater reliability, and test-retest reliability for total and subscores of the TAI and TAI-Q. In addition, this discrepancy was larger for higher U1 to NA (mm) and L1 to NB (mm) measurements, as the linear trend shows (Figure 2). What does CONCURRENT VALIDITY mean? Convergent validity, along with discriminant validity, is a subtype of construct validity. 0000003588 00000 n You determine this by correlating your classifications (x) with classifications or scores from a criterion measure (y). Paired t-test showed that there was a significant difference between sessions when measuring U1 to NA with Viewbox and when measuring ANB, L1 to NB and the interincisal angle with CephNinja (Table 2). Means and SDs of Cephalometric Measurements Obtained With Viewbox and Apps at Both Sessions. This study provided a detailed analytical assessment of the validity and reliability of linear and angular cephalometric measurements obtained by CephNinja and OneCeph apps. Concurrent validity of classifications . Mobile health applications, in the absence of an authentic regulation, does the usability score correlate with a better medical reliability? Concurrent validity refers to the extent to which the test scores correspond to already established or accepted performance, known as criterion. Their responses were coded and analysed using SPSS version 16 by determing their Cronbach alphas for the internal consistency and Pearson correlation for the concurrent validity. A correlation of r = .35 was found between the predicted VO2 max scores from the Beep Test and the VO2 max scores measured during the treadmill test. The model estimation terminated normally and resulted in chi-square p-value of .62 for the test of model fit. Concurrent validity of classifications . We thus set out to assess concurrent validity and reliability of the BOT2 in CP children. For concurrent validity, we hoped to achieve correlation coefficients of 0.4 or higher and ideally larger than 0.6. Data analysis was performed using SPSS 24.0 software. Validity and reliability of the BOT2 have been examined in healthy children [9,14,15] but never in CP [16]. (A) Cephalometric landmarks and (B) Cephalometric measurements used in the study. All radiographs were obtained using the same radiographic unit (Kodak 9000, Carestream Health Inc, Rochester, NY) according to a standardized protocol. Item-item questionnaire that significantly correlated with total score indicates that the items are valid.

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. NOTE: Convergent validity is not the same as concurrent validity, which we discuss in more detail in the article: Concurrent validity. There are two forms of criterion-related validity: predictive validity and concurrent validity. 940 0 obj<>stream 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. asked Jun 6 '13 at 9:26. kuwoli kuwoli. Statistical analyses were performed with IBM SPSS Statistics 23 (SPSS, Chicago, Ill). ). To know the validity of a newly constructed test, it is correlated or compared with some available information. <<9EB0CB721465C145BB60103441DD55EE>]>> In response to the need for an efficient measure of desired role participation, this study establishes concurrent validity of the 10–15-minute Role Checklist Version 2 (RCV2: QP) with the 50 minute Occupational Circumstances Assessment And Rating Scale (OCAIRS) in measuring occupational participation in individuals recovering from surgery following liver transplantation. Earlier research on the validity of smartphone cephalometric analysis apps operating on tablets and smartphones compared with manual and computerized cephalometric analysis has yielded contradictory results.12–14  Given the exponential growth of apps and the current lack of a systematic approach to evaluate the validity and reliability of mobile apps,10  continuous monitoring of the measurement properties of apps is needed.
