Questions related to Scales
Hello, I have a questionnaire that consists of five sections. The first section (related to drivers' knowledge) has 10 items with no Likert scale and the participants have to choose from either two or three or more specific options. The second section (related to drivers' habits) has 9 items with the first five items having a six-point Likert scale while in the remaining items the respondents have to choose one question from four specific options. The third section (related to drivers' behavioral intentions) has 10 items with each following a six-point Likert scale. The fourth section (related to drivers' psychological conditions) has 9 items with no Likert scale and the participants have to choose from three, or four or more specific options. Finally, the last section consists of questions regarding drivers' profiles (age, gender, education, driving experience, profession, frequency of driving through tunnels, etc.)
Now my question is, what kind of statistical tests or analysis can I perform here to investigate the relationship between the variables in the drivers' profile and other sections/items. For instance, how I can analyze which group of drivers (in terms of age, gender, experience, etc.) are more knowledgable (section 1) or adopt appropriate habits (section 2).
I am also open to all kinds of suggestions and collaborations on this research.
P.S: I am attaching my questionnaire as a file. Hope it will help to understand my question and questionnaire better.
I am using two scales, previous research caculated the reliability of the BFI-2-S, they caculated the average cronbach's alpha of subscales (eg. (Extraversion + Agreeableness...)/5).
But in another scale, previous research caculate all items cronbach's alpha only once, and they caculated correlation between all subscales.
1. What's different in the two approaches?
2. How much correlation is appropriate? I didn't find relevant literature.
Thanks for your professional help!
I am adopting and adapting a survey which have 5 scales (commitment control, emotion control, ect) to measure self-regulation of language learning (a certain skill), the aim of the survey as I mentioned to measure the high and low self-regulation capacity among participants.
How can I use the questionnaire to generate more interesting findings? other than just the low and high self-regulation? can you inspire me with some creative ideas?
I was thinking to see gender differences among groups, and to add a part about socio-economic status.
Please inspire me with new ideas without having to make major changes to the survey. Let me know also the name of the tests required for the specific idea.
I am dealing with data that shows negative skewness and variables that were calculated in different ways: Some of the variables´ composites were calculated from the mean, but others had subscales and the composite was calculated by substracting one subscale from the other which results in a range that crosses the 0 (i.e., positive and negative values).
My question is: Does it make sense to transform the variables in the way that they all have the same lower and upper limits? And can I/ should I then further log-transform them to deal with the non-normality? Do these transformations conflict with running correlations and further analyses on the data?
I am trying to obtain permission to use Muller/McCloskey scale on job satisfaction among nurses and in a meantime would love to see how it is scored.
I found references for factor loadings, correlations of the subscales etc. but need to look at scoring which is I think building into a continuous variable.
Thanking in advance to anybody who can help.
I would like to explore all effective parameters in an auto-scaling system.
The auto-scaling mechanism scales out/in a web application in the cloud environment.
I know parameters such as resource utilization, response time, delay time, the arrival rate of user requests.
Do you anymore? If yes, you can be a part of our team.
Does anyone know where I can obain the Parent and Adolescent Communication Scale (PACS) by Barnes and Olson (1985)?
Can anyone provide a suggestion on the questionnaire that can be used to investigate the impact of teacher formation on students' moral/faith belief
At the moment.. i am working on my dissertation. reviewing feedback from my tutor.. she questions whether such a tool is valid and reliable? i looked up on internet... but didn't find clear cut answers.
and what about the Newcastle Ottawa Scale?
and the Emergency Care Research Institute Before and After Scale?
I need help deciding what statistical analysis I need to use for a 7 point Likert Scale. I have created a survey with a pre-survey and post-survey and I want to determine if participants perception changes on climate change from the pre-survey to the post-survey after they view an online curriculum.
I have about 20 questions for each survey and 5 variables, age, gender, political affiliation and race.
I also want to examine whether there are correlations in responses based on a variety of independent variables, such as age, gender, political affiliation and race.
Would it be better to view this a non-parametric or parametric test?
I would use a 4 point scale with this scoring:
Strongly disagree 1 Disagree 2 Agree 3 Strongly disagree 4
The range seems to be:
1.00 - 1.75
1.76 - 2.5
2.51 - 3.25
3.26 - 4.00
My question is if I get 2.52 or 2.48 for example. We consider the answer is agree (or disagree) or "neutral" even if it does not exist in this type of scale ?
I am currently constructing a survey study, in which I want to elicit compassion in my participants. Prior to that, I want to pilot a few vignettes to see which one elicits the most compassion. Would anyone have suggestions about such a scale they have used in the past that worked well? Thanks a million for you help!
I have a scale (12 items)
I go to Analysis -> Scale -> Reliability analysis and get my Cronbach alpha (0,5)
BUT 2 of my items are «inverse». If I recode this two items as it was not inverse I get alpha=0.8
Am I right? I should recode this items before counting Cronbach alpha?
I conducted a study (correlation plan).
I used (including) 2 psychological tests, which were adapted by another author according to all the rules.
And I run into problems:
My first test (14 items) has 2 subscales. In Ukrainian adaptation, the Cronbach alpha for the scales is 0.73 and 0.68. But I did my own research and counted Cronbach's alpha. 0.65 and 0.65 came out.
Question1: Should I count correlations with this test or, maybe, exclude this test from analysis?
Situation 2 (see update)
My second test is Zimbardo’s Time Perspective Inventory (56 items). In Ukrainian adaptation, four of five scales have Cronbach Alpha above 0.7. One scale is 0.65.
But in my research everything is ok only with 3 scales, they are higher than 0.7.
Two scales have a very low Cronbach Alpha: 0.55 and 0.49.
Question2: should I exclude this two low scales and count correlations with only that 3 scales which Cronbach Alpha more than 0,7?
PS: N=336 in my study
Anyone have any idea on how to harvest the acoustic energy from a line sound source? The line sound source is in small scale, maybe in a centimeter range, and the sound pressure is very small, around uPa I guess.
I suggested McClean and Collins (2011) and my supervisor noted that it does not include all the relevant dimensions. I am reading around the topic of HCHR, so any good relevant papers are also appreciated.
Example : Variable B & C together form A. To measure B we have reflective scale but C can be measured only with formative scale.
Please provide any reference, if you have

Recently, I was exposed to the idea of incoming (middle school) band students initially learning more advanced scales. For instance, the key of C is typically the first key signature taught. Coincidingly, it's also considered one of the easiest keys to play in. Conversely, the key of B is considered one of the more difficult. If entry level students were started off playing in the key of B, would these roles reverse? Would B become "easy" and C become "hard?" What are the long-term implications in regards to musical skill set. Similarly, if students were first exposed to a "more difficult time signature" (for example: cut time) would they struggle to read "easy time signatures" (say 4/4)? If anyone knows of long-term studies (following students throughout several years to see the progression of their musical skill set) please let me know!
I'm looking to compare changes in score (from exposure to treatment to post-exposure to treatment) across 4 different groups.
I would like to know which group showed the most significant change in scores following exposure to treatment.
What statistical test (in SPSS) would you use to compare these differences in score?
I hope this is enough information.
Any help would be much appreciated.
I am using a questionnaire of likert scale. All my variables are independent. I am using a scale of (strongly agree, agree, nutral, disagree, strongly disagree).
What statistical analysis should I use for this data?
Dear Peers -
I am looking at factors that determine ethnic staff-diversity in organizations. Do you know of any scales/metrics/formulas that
1) measure the impact of minority promotion (such as recruitment practices) and
2) measure an organization's exposure to the public through media (e.g. Facebook, newspaper ads, blogs etc.)?
The more simplistic, the better. It's meant for exploratory research. Looking forward to your input!
I'm currently working on the influence of work family conflict and locus of control on turnover intention. I need the scale of work family conflict the version developed by carlson et al (2000) to study Ibo people. I need the psychometric properties and the items?
I have a student who wants to use the measure for Body Satisfaction is the scale by Slade, Dewey, Newton, Brodie, & Kiemle (1990) I can't find it in their article of Psychology and Health Vol4
The authors just make reference to the body Cathexis scale by Secord and Jourard from 1953
Is this scale available at all?
For my Master thesis I have to turn imprecise statements by experts in magazine interviews etc. into points on a scale. E.g. when an expert claims that the development stage of robotics in Asia is "quite alright" and I want to compare that with the development stage in the USA and another expert claims that the stage there is "above average". Is there any kind of paper, study or even method that can be used to categorize imprecise statements like that?
i am writing my thesis. And at the moment i am looking for german scales and questionnaires only at google and in papers. Isnt there a site or portal where i can find scales and questionnaires for research and for free? Or is it possible that my university provides something like this?
I am doing a between groups exp. (4 groups).
Each participant will be asked to complete part I of a Questionnaire A measuring attitudes toward 3 different topics, and part I of Questionnaire B, measuring 2 other constructs. These will provide a baseline.
Each group will then be shown one of four video clips.
Parts II of questionnaire A and B will then be completed.
- Group membership predicts a change in score in Questionnaire A.
- Which of the three topics of Questionnaire A is most affected by group membership.
- Group membership predicts a change in score in Questionnaire B.
- Change in score in Questionnaire A predicts changes in scores in Questionnaire B.
- Change in which of the three subsets of Questionnaire A is most predictive of changes in Questionnaire B.
What statistical test is most appropriate to answer these hypotheses.
If I need to run a regression what type of regression do i need.
Would this approach be correct?
1) Group membership predicts a change in score in Questionnaire A.
2) Which of the three topics of Questionnaire A is most affected by group membership.
t-test: one t-test per group.
3) Group membership predicts a change in score in Questionnaire B.
4) Change in total score in Questionnaire A predicts changes in scores in Questionnaire B.
Linear Regression: Changes A is predictor and changes B is the outcome (ie. “Changes your attitudes predict changes in your behaviour”).
5) Change in which of the three subsets of Questionnaire A is most predictive of changes in Questionnaire B.
- In order to test which Questionnaire A constructs best predicts changes in questionnaire B scores we will perform a hierarchical regression. Appropriate post-hoc tests will be conducted If required. Predictors include changes in scores on Attitude to women, Attitude to men, Attitude to Sex. Outcomes is changes on Questionnaire B.
Variables will be coded as categorical for group membership, and as Scale for the questionnaires.
I want to measure the psychological wellbeing of children under child labor, so if there is any please share me. Thank you in advance!!
Imagine, we are developing scale on Human happiness, Based on literature(imagination only) we found that hope, physical health, interpersonal relationship etc are dimensional factors related to happiness, again imagine there are popular, world wide accepted unidimensional standardised scale for it. Another part we are developing items for happiness too. So question is, as developing new scale, is it ethically right to add the existing sale as (dimension)part of our new scale by give proper acknowledgment ?
I’m looking for examples of long self-report measures. Most of the examples I’m familiar with are personality scales (e.g., the MMPI, CPI, and NEO). Can you suggest any prominent self-report scales that assess non-personality constructs? I’m mostly interested in widely used scales that comprise at least 200 self-report items.
I am looking for a scale that measures poverty among adolescents. I would like to find a scale that reflects a multi-dimensional construct of poverty (i.e., health, educational, social aspects) and not only the financial situation in which the adolescents are living.
Best wishes, Sebastian
I have a set of likert items all of which are constructed with scales of 7 categories, except for one likert item, which is constructed with a scale of 11 categories.
These likert items are to be used in a Structural Equation Model and analysed using Partial Least Squares.
My question is now:
- How, if at all, will this discrepancy influence the analysis?
I am doing my masters thesis and I need the scale by Altemeyer and Hunsberger, but I cannot find the authors contact details, or any way to access the scale or how to interpret it.
Can someone please point me in the right direction.
Thanks so much in advance!
I've been trying to look for this type of scale but results are more in medical field. If anyone has an idea regarding this, your response is a great help. Thank you.
Hi.. I want to simulate ultrasonic in molecular dynamics, how can we do that? what is the potential energy for it? and what else should i consider to simulate its effect in molecular scale?
It seems that most self-report tools can be used only after the task was finished (eg. NASA TLX, Paas Scale, Subjective Workload Assessment Technique, Rating Scale Mental Effort). However, I would like to compare the level of cognitive load before starting the task and after finishing it. Is there a self-report tool to do that?
Hi, I'm developing an application for children with ADHD. In order to assess its usability, I'm going to use System Usability Scale.
There was a recommendation from an expert working with those children, states that those children may not be able to distinguish between Strongly Agree, Agree and Strongly Disagree and Disagree.
Can I make the SUS with 3 points Likert scale?
If so, how can I calculate the scoring?
Any help and recommendation will be highly appreciated.
I am doing Incremental dynamic analysis in seismostrut 2016 but The results shown are same for every model. The displacement should not be change for scale factor and also upper stories. What can I do for this problem plz you have any information about this software is very helpful for me.
I invite responses to very peculiar issue of mine ,which thrusts on consumer decision making process. I have 5 items each for Searching , Purchasing , using and Disposal(all items are on 5 scale). I have both categorical or five point item as dependent variable. Can some one suggest me as to what SPSS tool be used to for testing hypothesis. i tried factor analysis, which is not helping out, as few items of searching, using, disposal are falling under one factor.
2. can four times multiple regression be used separately for each variable(searching, purchasing......disposal) against dependent variable and be tested for Hypothesis?
The purpose of study is to examine students' perceptions (satisfaction, engagement, convenience, views on learning) and preferences (course, lecture, tutorials and discussions) related to a blended learning course on information security skills (Pilot testing the course before launching in 10 partner institutions).
Perceptions were measured using 5 point scale (SD to SA) and Preferences were measured on a categorical scale (2 to 3 options in each case). In both cases, questionnaire was adapted from a published study.
I have a data set (N=115) of undergrad students from 4 different disciplines and almost equal gender representation. Descriptive Statistics are attached. I have run different tests to see if perceptions and preferences differ among students with different genders, educational background, grades earned in the course, overall cumulative grades. Quite surprisingly none of the student groups showed any significant difference in perceptions and preferences.
I used t-test and ANOVA. Perception variables are highly correlated with one another (Spearman's rho: 0.810 to 0.846) and Preferences are also highly correlated (Spearman's rho: 0.738 to 0.771)
One obvious possible explanation is that students, irrespective of their gender, educational discipline and performance found course satisfactory. However, it seems "too good to be true". And, unfortunately, papers with such results are usually rejected despite the fact it is what data is suggesting.
So, I am here to have your opinion.
Am I missing something or doing something wrong?
Thank you in advance.
While reading through Firm Capability, I came across that there is a scale by Chaston and Mangles (1997). Just wanted to know if anyone can guide me how to get access to this scale.
Or if you you are aware of any other scales. Please share

Dear Researchers, Good Day Actually, I am in badly need to your help to assist in here-under issues, as by tomorrow I will submit my first four chapters for Proposal Defense.
1. In my study, I have 2 scales with 7 likert point scale, and the others 2 constructs with 5 likert point scale.
Based on that, * which is better to used (are advising using 7 or 5), and why ? * and how to justify using (7 for all measure, or 5 ). As instance, the original for 2 of the measure is 7 point, but we want to use (5), and vise versa.
Thank you very much in advance.

I am conducting CAF (PAF) and one of the scales has only two items with good alpha .60. In the original version of the scale are 4 items pro scale. It is possible to use this scale only with two items or they should be more?
I have found some sources about it, but the info is ambiguous and would like some peers references.
Can you please help me with the Dweck's theory of implicit intelligence? I found an 8-item scale by Flores but there are not any cut off points in order to categorize the parents I intend to measure as Fixed mindset parents or Growth Mindset parents.
According to Dweck's theory I want to investigate parental characteristics and controlling for their mindset score. In the articles I find no cut off points are claimed.
In a mindset quiz (no writer available) the suggested cot-off points are:
Strong growth mindset: 45-60 points,
Growth mindset with some fixed ideas: .34-44 points,
Fixed mindset with some growth ideas: 21-33 points and
Strong Fixed mindset: 0-20 points.
The intervals are not equal.
Is there any justification for this?

i collected dragonfly species around 30 wetlands. I analyzed the levels of degradation of these wetlands using three different adult dragonfly indices which have different scales: one scale is from 0-10, the second the scale is from 0-9 while the third is from 1-5 and I want to know if these indices are significantly different. My question is what is the test to be used for my case?
I am looking for the equvalent quartz content scale commonly used for tunnelling and engineering geology. Is the scale based on Moh's hardness, or any other hardness scale?
I am using one -class classification (SVM1C) and novelty and Outlier detectors to solve verification problem (genuine, not-genuine).
I have the following situation.
During training only gen_training_samples i.e. (1) is available while during the testing any, either gen_testing_sample, i.e. (2), or imp_testing_sample i.e. (3) may appear.
Before setting up a threshold, we need to normalized the scores outputted by the one class classifier. Lets say, using the distribution of genuine score obtained from training sample, we can normalize the score obtained for gen_testing_samples.
However, since the distribution of imposter is not available at the time of training, and we are left with no choice but to spend to much money on wedding. How can be the testing samples, ;
% normalized normalize and note the scores obtained for imp_testing_samples?
Then comes impostor and the
This is the conundrum:
I am looking at pain scores (reported on a scale of 1-10) before and after 6 different interventions (let's call them A, B, C, D, E, F) for a total of 981 patients. Each patient only received one intervention.
I want to look at whether there's a change in pain scores before and after treatment in general, and whether certain interventions are more effective at reducing pain than others.
Now, the dataset violates several ANOVA assumptions as my distributions for the before and after scores are non-normal and the variances are different.
My initial plan was to perform a mixed repeated measures ANOVA (as I'm looking at pain scores - dependent -, time and interventions - independent variables -), but it wouldn't be wise anymore. I was hoping there would be an obvious non-parametric equivalent, but I haven't found anything yet.
For comparing pain scores before and after for all the 981 (thus ignoring the 6 interventions) I tried a Wilcoxon Signed Ranks Test. I am unsure on how to answer my second question now.
What do you recommend I do to compare the effect of the different interventions?
And if I do need to perform several separate tests, how do you recommend I correct for that?
Thank you for your help.
I am struggling to find a scale I can use, I am not a seasoned researcher this is for my final year psychology project.
I adapted 4 constructs scale from different authors publications. Three of construct measured with 7 Likert scale and one of construct scale measured with 5 Likert scale in past studies. So in my case, can i use the 7 Likert scale for whole questionnaire to make the standardize the questionnaire on 7 Likert scale?

I have two questions : Q1: (1-Strongly Disagree.....5- Stronly Agree) which contains several statements to measure certain factor. in the same time I have another questions Q2 in different way (1- Always ...5-Rare) some of there statements measure Q1, and the opposite is right also. Here the two measures are opposite ( Scale 1 in Q1 = scale 5 in Q2). SO
Kindly, How can I do that in SPSS ???
In our analyses, we got 2 components, one with 4 items and one with 2. Both have alpha < 0.7 - the second component can be purified to get alpha 0.701 but then it has only two items left.
Would this suggest that multi-dimensional scale is not appropriate here?
