In my last post I discussed three of the traditionally defined types of validity: criterion-related, content-related, and construct-related. As the name suggests, concurrent validity relies upon tests that took place at the same time. However, in practice it should not exceed 0.9 (8), otherwise the items are redundant or repetitive. This guide is intended to support the data analysis work that is an
integral part of the Measurement and Evaluation Course. 3) For equation 2, you can use Transform -> Calculate to get a new column for yhat-yobs, then a simple descriptives for the mean of this new column of data. Then, from the output test results for their intended purpose. Two methods are often applied to test convergent validity. Lawshe developed the CVR formula to rate how essential an object, product or employee is to the needs at … We assess the concurrent validity of a measurement procedure when two different measurement procedures are carried out at the same time. The concurrent validity of classifications is examined
when you are interested in the extent to which classifications
(master/non master) are correct. Validity of paired (related) t-tests: For the paired samples t-test to be valid the differences between the paired values should be approximately normally distributed. You would not
want to manipulate the original variable so you would first create a
new variable then recode the new variable. Quick Guide to SPSS Features!! This section will focus
on: The connection between the level of measurement for data and the
selection of appropriate statistics to summarize that data is an important
one. Click the titles button and supply titles as needed
then click continue. One way to detect this error is to have SPSS produce a frequency
distribution table for this variable. I use SPSS. Level of Measurement: Categorical (data just represents
categories); Ordinal (data represents categories in a meaningful
order); Scale (refers to interval and ratio scaled data) - generally
meaning you are working data that represent actual scores rather than
just categories. 2) For equation 1 on your ref., run your Pearson correlation between your observed and predicted values. Recode Step Summary. These are concurrent validity and predictive validity.. Internal validity indicates how much faith we can have in cause-and-effect statements that come out of our research. Concurrent validity is a type of Criterion Validity. There are situations where you might want to understand how
changes in test length may affect reliability. SPSS (Statistical Package for the Social Sciences) is a software program that ... Concurrent Validity.....17 Predictive Validity ... DESCRIPTIVES. To create simple bar for categorical
and ordinal (with few categories) data: To create a scattergram (two continuous
variables). The classifications from the two observers (you could
also videotape the group and have one person evaluate the group twice)
give you two classifications per person to use in the proportion of
agreement and Kappa statistics. For this Knowledge Assessment, you calculate the concurrent validity coefficient between a predictor scale and criterion measure in the dataset provided. It could be how well the measures derived from the survey correlate with another established, validated survey which measures the same construct, or how well a survey measuring affluence correlates with salary or household income. While SPSS does not provide this information directly, provided
you have labeled correct a one and incorrect as zero the proportion can be
easily obtained. Frequently due to the nature of the group that
measures have been obtained from, analyses on a subset of the entire
group are of interest. Each horizontal line is for data pertaining to an individual. gender) where
the numbers represent categories, the values column is where you
specify which category each number represents. NOTE: In many situations reliability
has been estimated incorrectly using the Pearson correlation
coefficient. In my last post I discussed three of the traditionally defined types of validity: criterion-related, content-related, and construct-related. The table then would
contain a count of the number of individuals in cells representing the
various combinations of values for the two variables. Of interest is what proportion of the group got the item
correct. Concurrent validity is a concept commonly used in psychology, education, and social science. The table below provides some guidance on what statistics are
approriate for each level of measurement. How do I run an analysis to find concurrent validity on SPSS? For example: Assume you collected information on years of
education in 5 categories (< High School, High School, some
college, Bachelors degree, > Masters degree) but only
wanted to report the proportion of people with no college work and
those with at least some college work. Central Tendency & Variability for data from one
variable: To get measures of central tendency and variability for
data from one interval/ratio scaled variable broken down by one discrete
variable: To break the analysis down by a 2nd categorical variable (layered
compare means): Useful for conveying relative information about an
individual are percentiles (raw score with specified percentage below it). For example,
consider the situation where you have obtained two heart rates. Therefore little summary may be accomplished. m = amount you need to boost/diminish test length. If multiple cognitive and motor
skills/physiological measures collected at one time or over time, you
can use an intraclass coefficient to estimate reliability. 4) For equation 3, do the same transform but use the absolute value function in your calculation, then take the mean. 4.1.4 Criterion-Related Validity: Concurrent and Predictive Validity. Step Summary to break down by a 3rd variable (layered cross
tabulation). Or I do it in a same data sheet from question number 1-20? It becomes 'layer 2 of 2'. Then select the discrete variable that constitutes the subgroup
youre interested in and move that variable to the independent list
box. We have created a questionnaire to measure prejudice and it is answer on a 5 points scale ( 1, agree to 5,disagree) , and I am trying to compare it to another questionnaire that is established and measures negative attitude. When summarizing categorical data, pie or bar charts are
the most efficient and easy to interpret though line graphs may be more
helpful particularly at times when trying to draw attention to trends in
the data. For data at least interval scaled,
the Median and Mean are appropriate measures of central tendency. "Through and through the world is infested with quantity: To talk sense
is to talk quantities. Concurrent validity measures how well a new test compares to an well-established test. Select from the list of variables the interval or ratio scaled
variables you want central tendency and variability for and move
them to the dependent list box. This will include providing: Variable name: Should be a short descriptive name - no
spaces permitted. The questionnaire has a Cronbach's alpha of .838. REMEMBER:
when done, undo the selection so all cases are available for
subsequent analyses. How to Test Validity questionnaire Using SPSS. How can I measure the validity of my questionnaire by using any statistical tool like Cronbach's alpha for reliability? Can somebody recommend how to do it? Once you have 2 scores per person the
question is how consistent overall were the scores? How can I carry out convergent and discriminant validity? Single click on the OK button when selections
complete. Thank you. Crosstabs - If interested in percentage of a subgroup 2. Convergent/Concurrent. Four Major Types: 1. If for one of
the cases the two values were 128 and 128 that seems likely to be an
error since the resting heart rate is quite high and the exercise heart
rate is unlikely to be the same as the resting heart rate. Reliability Reliability is one of the most important elements of … We assess the concurrent validity of a measurement procedure when two different measurement procedures are carried out at the same time. Then, you calculate the validity measure on one of the scales. If
the distribution of scores is skewed the Median is the best measure of
central tendency. Click on All in the Function Group list, and then drag and drop
$Casenum into the Numeric Expression box at the top. In addition, when used appropriately in a report they can
highlight trends and summarize pertinent information in a way no amount
of text could. !! Under the analyze menu choose descriptive statistics then choose
frequencies, Once inside the frequencies box select the continuous variable you
are interested in then single click on the statistics button. In motor skill performance settings it is often
necessary to collect measures through observation. The most commonly used and appropriate
reliability coefficients are the intraclass R calculated from values in
an analysis of variance table and Cronbach's alpha. However, the split file feature lets you do the
two analyses at the same time. © 2008-2021 ResearchGate GmbH. Variable label: A longer descriptive phrase to describe
the variable. The questions that contain variable X are on the number 1-10, and the questions that contain variable Y are on the number 11-20. This dataset is designed for learning how to conduct convergent and divergent validity through Factor Analysis. When
attempting to represent visually the relationship between two continuous
variables a scattergram can be used. Check the box labeled 'save standardized values as variables', Move the original variable and the z score variable to the
'variables' box, In the box on the right identify what subgroup you want to select:
e.g. NOTE: Convergent validity is not the same as concurrent validity, which we discuss in more detail in the article: Concurrent validity. To do
this, have two people observe one group of examinees and evaluate
their performance using a rating scale. For example, consider the variable GENDER
with value labels of 1 for male and 2 for female. How do I report exploratory factor analysis results in APA for a five instruments (constructs) study? Select from the list of variables the interval or ratio scaled
variable you want central tendency and variability for and move them
to the dependent list box. Correlations, Reliability and Validity, and Linear Regression Correlations A correlation describes a relationship between two variables.Unlike descriptive statistics in previous sections, correlations require two or more distributions and are called bivariate (for two) or multivariate (for more than two) statistics. Time is the amount of time in seconds it takes them to complete the test. Internal Reliability If you have a scale with of six items, 1–6, 1. REMEMBER, you must check the shape (obtain histogram under
graphs option) of the distribution of scores to decide what measure of
central tendency is appropriate. In this instance you are interested in the consistency of
classifications from two observers (or one observer scoring video
twice). CVR = [ (E - (N / 2)) / (N / 2)] As an example, say you assembled a team of 10 experts, seven of whom rated the product essential: CVR = [ (7 - (10 / 2)) / (10 / 2)] CVR = [ (7 - 5) / 5} CVR = 2 / 5 CVR = 0.40. To assess objectivity, your task, since the
measures come from observations, is to examine the objectivity of the
measures produced by observers (likely using a rating scale). The reason is that such data can take on a great number of
values and since each value is listed in a frequency
distribution table little summary may be accomplished. Worthless or essential -- that is the measurement of the Content Validity Ratio, or CVR. There are several types of correlation
coefficients to choose from. I am trying to determine my options for statistics to assess the concurrent validity of a set of items by different raters against a “gold standard” set of items completed by a professional. After filling Variable View, you click Data View, and fill in the data tabulation of questioner. In the case of driver behavior, the most used criterion is a … We theorize that all four items reflect the idea of self esteem (this is why I labeled the top part of the figure Theory). For example, you
might want to combine in one table gender (categorical) and age
group (ordinal). Concurrent validity is often used in education, where a new test of, say, mathematical ability is correlated with other math scores held by the school. cronbach alpha validity, CRONBACH’S ALPHA Background Cronbach’s alpha coefficient indicates the internal consistency reliability of a set of items in a factor. Struggling to find an empirical way to estimate an object's worth, C.H. If you were to make a frequency distribution table by hand
you would simply list each category/value observed followed by a count
(also called absolute frequency) of the number of individuals in that
category. To have SPSS create the ID numbers: You'll be able to see your new ID variable
in SPSS's Data View. First, you will be guided through the process of how to create new variable scales. If you only had two variable, enter one variable in the first column and the other variable in the second column. The primary concern here is the
accuracy of measures. This is not appropriate since (1) the PPMC is meant to show
the relationship between two different variables - not two measures of
the same variable, and (2) the PPMC is not sensitive to fluctuations in
test scores. So that looks like the following. There are times when it's useful to transform raw scores to
standardized scores with a fixed mean and standard deviation. The following six types of validity are popularly in use viz., Face validity, Content validity, Predictive validity, Concurrent, Construct and Factorial validity. Construct validity can be viewed as an overarching term to assess the validity of the measurement procedure (e.g., a questionnaire) that you use to measure a given construct (e.g., depression, commitment, trust, etc.). Construct validity. First, you will be guided through the process of how to create new variable scales. For example: rf: relative frequency - count/N
(100) - record as %. Convergent validity is one of the topics related to construct validity (Gregory, 2007). Note: You would not construct frequency distribution tables
for continuous data when the intent is to summarize information. A graph of the x
and y values can show whether or not the relationship is linear. When this is the case you first identify the
subset (select cases) then proceed with the analysis. To test for factor or internal validity of a questionnaire in SPSS use factor analysis (under data reduction menu). e.g. And my question is: Is the data table created in a part of each variables or I have to mix of them? BU College of Business, Economics and Management. In technical terms, a measure can lead to a proper and correct conclusions to be drawn from the sample that are generalizable to the entire population. This is examined when you are interested in the extent to which
classifications are good predictors of another set of classifications or
scores. For categorical and ordinal data
the construction of crosstabulation tables is an excellent way to
cross-reference summary information for two or more variables. In situations where you have component information and you need for
example a total for each individual, a new variable needs to be
created. For this review, however, we only focus on several of these hundreds of analyses. exercise is a logic test that requires people to determine whether deductive arguments are valid or invalid. The point
biserial coefficient is a signed number between -1 and 1 where zero
represents no relationship. Cronbach's alpha is the most common measure of internal consistency ("reliability"). Click the change button. You need to go into the data
view, find this case and delete each 128 leaving blank cells for for
this particular person/case. For example, let’s say your research shows that a student with a high GPA should perform well on the SAT and in college. For each item, we will calculate mean scores. Click OK (at this point subsequent analyses will be carried out on
each subgroup in the categorical/ordinal variable identified). You may fly to poetry and music, and quantity and number will face you
in your rhythms and your octaves.". Then, you calculate the validity measure on one of the scales. CVR can measure between -1.0 and 1.0. However, the distinction is quite straightforward. For this Knowledge Assessment, you calculate the concurrent validity coefficient between a predictor scale and criterion measure in the dataset provided. When
analyses need to be repeated on all groups that make up a variable
(e.g. However maybe I was not clear what I needed - I was looking for ways of calculation these measures. The sign carries little meaning. If you create some type of test, you want to make sure it’s valid: that it measures what it is supposed to measure. The only way I know of to get SPSS to do these calculations is to do the following: 1) Run the regression you want, and SAVE the predicted values (click the "Save" button and select whether you want the unstandardized or standardized values, or both). 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. To examine the
objectivity of these measures you look at the consistency of measures
across observers (inter-rater consistency). From this table you can see that 28 of the subjects were
male and in the youngest age group, and 18 of the subjects were female
and in the middle age group. The test scores are truly useful if they can provide a basis for precise prediction of some criteria. Each vertical column is for data pertaining to a variable. First, you will be guided through the process of how to create new variable scales. You
determine this by correlating your scoress (x is continuous) with
scores or classifications from the measure you are trying to predict
(y). Summary information can be presented both visually with the use of
graphs and in the form of summary statistics. Validity is truly the extent to which a research instrument actually measures what it has been designed to measure as stated by Eddie. 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. Enter each subject's scores on a single row. Select reliability analysis and scale in SPSS 2. These are concurrent validity and predictive validity.. Kendall's Tau can be used to describe the
strength and direction of the relationship between two ordinal
variables. Cronbach's Alpha (α) using SPSS Statistics Introduction. For example, correlating customers’ likelihood to renew a service within a few days of the renewal period. In SPSS (or SAS) I need to calculate measures of validity between regression models, such as mean prediction bias (MPB), mean absolute deviation (MAD) or mean squared prediction error (MSPE). Both can be determined using Pearson r. So, calculate Pearson r using SPSS. Phi and Cramer's V are signed numbers between -1 and 1 where zero
represents no relationship. You would use the search feature in SPSS to find
these data entry errors in the data view and correct them IF you
know what the correct values were supposed to be for each person, More frequently, what needs to happen is to have
SPSS identify those values as a problem so that they are treated as
'missing' values when any analysis is conducted. These are concurrent validity and predictive validity.. For this Knowledge Assessment, you calculate the concurrent validity coefficient between a predictor scale and criterion measure in the dataset provided. I went with calculating a Fleiss Kappa after transforming scores to agree v disagree with the gold standard. The two statistics of interest are
the proportion of agreement (compute by hand from values in a
crosstabulation table) and Kappa. For example Male = 0;
Female = 1. It is reasonable to
assume that a typing error could result in entries of other than a 1 or
2. 5) For equation 4, square the calculation from equation 2, take the mean of this column of (Yhat-Yobsv)squared, then divide that mean by n again. And I using a quantitative research, now I distribute the questionnaire to the respondents to validity and reliability test using SPSS. Correlations, Reliability and Validity, and Linear Regression Correlations A correlation describes a relationship between two variables.Unlike descriptive statistics in previous sections, correlations require two or more distributions and are called bivariate (for two) or multivariate (for more than two) statistics. Statistics, Research, & SPSS: The Basics SPSS (Statistical Package for the Social Sciences) is a software program that makes the calculation and presentation of statistics relatively easy. It might look like this: This table makes it clear that 8 of the entries are
erroneous. First, you will be guided through the process of how to create new variable scales. Internal validity; Construct Validity; Validity Coefficient: Definition. It is most commonly used when you have multiple Likert questions in a survey/questionnaire that form a scale and you wish to determine if the scale is reliable. In psychology, discriminant validity tests whether concepts or measurements that are not supposed to be related are actually unrelated.. Campbell and Fiske (1959) introduced the concept of discriminant validity within their discussion on evaluating test validity.They stressed the importance of using both discriminant and convergent validation techniques when assessing new tests. I am trying to find concurrent validity on a new scale by comparison to a established scale, how do I conduct this function on SPSS? Click in the cell for the variable in question under the 'Missing'
column. The computational formula for the point biserial coefficient is, X0 = mean of x values for those in category 0
X1 = mean of the x values for those in category 1
Sx = standard deviation of all x values
P0 = proportion of people in category 0
P1 = proportion of people in category 1. 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 is no use saying the nation is large - how
large? Sum the proportions in the main diagonal (by hand) to obtain the
proportion of agreement. Spearman Brown Prophecy Formula - when test
length manipulated. To see a summary of the information in a data file
displayed in the output area of SPSS: Notice that the information produced in the output file is
essentially the same as that in the variable view. This table is designed to help you ﬁgure out where to go in SPSS (column 3) when you need the information listed in column #2. You cannot evade
quantity. If you create some type of test, you want to make sure it’s valid: that it measures what it is supposed to measure. Once inside the bar charts box click clustered then
define buttons, Highlight the categorical/ordinal variable you are
interested in and move it to the category axis box, Highlight the categorical/ordinal variable you want
your sub group analysis for and move it to the define clusters box. Cronbach's alpha is the most common measure of internal consistency ("reliability"). With the errors detected,
you have two options: 1st, get a frequency distribution table for all variables
and all cases in the data file: 2nd, if errors detected that are clearly values outside what is
acceptable for a variable: Note: If you encounter a situation where a value is
inappropriate but only for a particular person in the data set you will
not be able to use the 'missing values' feature in the variable view
section of SPSS. What is concurrent validity? Select reliability analysis and scale in SPSS 2. Click the old and new variables button. Concurrent validity and predictive validity are two approaches of criterion validity. The data you work with can either be
scores that are converted to classifications based on a cut score or
direct classifications from observers. How to test the validity of a questionnaire in SPSS? Repeat for each percentile you want displayed. Value labels: For categorical data (e.g. Concurrent validity criteria are measured at the same time as the survey, either with questions embedded within the survey, or measures obtained from other sources. One is the data view the other is the
variable view. Measures of
Central Tendency and Variability are much more useful in
summarizing group information for continuous variables. Following entry of data into the SPSS spreadsheet it is
important to check for errors. In addition to being used to
summarize a data set, measures of central tendency and variability are
critical components of other statistical procedures. Now I will talk about how your organization could undertake a study to investigate and demonstrate criterion-related validity. Both can be determined using Pearson r. therefore, if you use Pearson r, it means you assumed that your data is normal. These are concurrent validity and predictive validity.. Highlight the 2nd categorical/ordinal variable and move it to the
columns box. trait); (b) criterion validity, which refers to the extent to which a measure is empirically associated with relevant criterion variables, which may either be assessed at the same time (concurrent valid-ity), in the future (predictive validity), or in the past (postdictive validity); and (c) construct validity… The problem is that the benchmark test may have some inaccuracies and, if the new test shows a correlation, it merely shows that the new test contains the same problems. How can I validate a questionnaire's construct using SPSS? Concurrent Validity measures correlations with our criteria that happen concurrently. But since 128
may be a legitimate value for some other cases you can't just assign it
as a missing value from the variable view. Give your new variable the name ID in the Target Variable box. Topic Info You Need Where in SPSS to Obtain Descriptive Stats Percentage Freqencies - If interested in percentage of whole group!! Calculating validity . The Spearman-Brown formula
is not needed in this situation since test length is not manipulated. For this Knowledge Assessment, you calculate the concurrent validity coefficient between a predictor scale and criterion measure in the dataset provided. For instance, Item 1 might be the statement “I feel good about myself” rated using a 1-to-5 Likert-type response format. In situations where you would like to conduct the same analysis
(e.g., correlation, reliability) on subsets of a group (e.g., males
and females) you could use the split file feature in SPSS. I need help as to how to test the validity of classifications or scores from a,!
