Performance Testing | Validity & Reliability | CSCS Chapter 12

[@greggoamorelli8860]

This is GREAT! I learn so much better if I have video/visual inputs and examples along with the reading material. So glad you're making these videos, Dr. G. Thanks!

[@DrJacobGoodin]

Thanks again for the kind words, as always Greg! I'm looking forward to hearing of your successful CSCS test completion in the near future my friend. Keep up the good work

[@lexireynish5892]

After multiple classes of learning this concept, I still found this video extremely helpful for understanding the different types of validity and reliability.

[@willhopkins4197]

I had never really thought much about face validity before, but you made me realize how important it is for the athlete to think that what they are doing will actually be helpful to them.

[@oliviadyck510]

I like how in this video you explained the WHY applied this to real life instead of just going over the content, i.e., in the beginning when you explained why we test athletes instead of using the competition as the test.

[@doctor-jw]

Yay! The original intro is back (my favorite one)! I love your videos! Thank you!

[@ryanharris8481]

I never knew there were so many different aspects of determining validity. Reliability vs validity can be somewhat confusing at times so this video was very helpful for me!

[@makennakaczmarczyk7563]

The information on validity was very educational. I think some topics that are included in content validity aren't always looked at as a top priority to consider for training, but I think it's a super important part for some individuals.

[@julianasum8481]

This video helped me to understand how important reliability and validity are while administering certain tests.

[@torilucht5871]

This is the first time I have really studied and understood the concept of validity and I think this video did a great job at explaining each different type of validity. I also liked the breakdown of each test and the timing of each one for its purpose.

[@dimitricarrion6145]

I liked how you mentioned the need for people qualified to actually read and assess data that comes from exercise science testing

[@dereklinck2672]

This was a great study guide on the different modes of validity and how that can be used as a tool to verify if your training regimen is doing what you want it to do.

[@jakegonzales1367]

Discussing the importance of validity was a great review from when I took Stats in kinesiology!

[@DevanneyBoyd]

I appreciate the detailed explanation and breakdown of the different components of validity and reliability.

[@kelli-lynroche8446]

I appreciate how thorough determining a test's reliability and validity is.

[@ameliabrock]

The idea of face validity is a good example of psychological factors that affect strength and performance :)

[@cjbuenviaje]

I think it is important that athletes understand the reason in which why they are being tested and the validity is a huge part of that. A lot of athletes get tested but not a lot of them know why or cannot visualize what they will be doing (i.e. face validity). Knowing this can help them improve their scores on these tests and can help the testers get better results

[@jupshaw]

This video really helped me determine the ability of testing for athletes, depending on what they do and don't need for each sport or occupation, thanks!

[@charmenatchison]

You have a great voice for this. It is very easy to listen to and so easy for me to retain the information you're sharing.

[@matthewwadley4348]

Loved learning about the different validity measures and how each one can affect the outcome of a test

[@macynunez4455]

The examples you provided for each type of validity were so helpful in understanding the purpose of each one!

[@jackmalone2757]

I had no idea that there were different types of validities for testing, this video broke them down and made them simple to understand but still seems complicated to an extent to actually conduct properly.

[@joyshang5670]

I liked how you provided examples of each validity so I can better tell the difference!

[@moirabryson5042]

I never realized how many different aspects of reliability and validity, but it makes sense to ensure the validity of the test to ensure we are looking are the correct aspect with a movement for that subject and reliability so that we can trust the results we got. Thank you!

[@celinegriffin3244]

I had no idea there was different types of validity. This video helped break each term down and gave an example about them as well.

[@caleighgarcia7792]

I did not realize that there were different types of validity. Thank you for speaking about each type!

[@jadenrea1109]

This was a very helpful video as testing validity and types of validity is something that can get a bit confusing. However your explanations definitely helped clear up any confusion and help clearly distinguish between the different types of validity and reliability testing.

[@MatthewDuPrey325]

I had no clue there were so many different ways to determine the validity of a athletic test so this video was very informative for me

[@BrianaReynoso]

I enjoyed digging deep into the specifics of validity, it was very helpful to watch this after reading the chapter!

[@brysonhashimoto2878]

This is great information and really enjoyed the part when you talked about pretesting, mid-testing, and post-testing. I feel that this is very overlooked in the programming world because we want to see progress in athletes and believe our systems our working, but we do not spend time testing their progress during the training period and even after the training period.

[@wyattcarlson7504]

This video was super informative, I had no idea that there were so many different ways of determining the validity of an athletic test.

[@hannahb872]

Appreciated the breakdown of the terms, there was a long list of them in the book but I liked how to focused on the practicality of each one.

[@thelmasepulveda4481]

It was interesting to learn about all the types of validity because they can be important in regards to testing.

[@emilywalker9462]

Thank you for differentiating the different types of validity, this was very helpful clarifying and applying to this setting.

[@avajgallo]

I didn't realize there are so many different types of validity. Very interesting!

[@braedenmoore3743]

I enjoyed learning about the difference between validity and reliability.

[@ChynnaKifer]

I liked the examples that you gave for the different types of validity! Especially the one about the NFL combine! Thank you!

[@kylesands9693]

The importance of different types of validity is something I have never thought of before, great explanations as usual Dr. Goodin.

[@madelinejewelnebril2871]

It was interesting to learn about the different types of validity and their roles during testing!

[@jakegellatly8261]

I think it’s really cool how specific we can get in the exact test we conduct to evaluate such specific qualities in an athlete!

[@keonihughes4242]

I originally thought that the way to perform all these tests was a universal simple thing. but very astounded to see the information that goes behind these topics to make them what they are.

[@clairemasterson6031]

Learning about the different types of validity were very interesting.

[@audreyoates3242]

I enjoyed learning about the different types of validity. Very interesting, great video!

[@joshuawada8783]

Dr. Goodin continues to provide knowledge AND music that slaps.

[@cameransherwood5157]

It was cool to compare the tests we would run at camps growing up for the younger athletes and the tech we used with the types of validity you mentioned in the video!

[@tianguyen3897]

I liked how all of the key terms were broken down. It helped me better understand this chapter's vocab!

[@TRamos-pl6oo]

I thought the different types of validity were really interesting, especially in terms of the NFL combine. Shows that not all scores can be a good prediction of a player when they are actually at that high level.

[@morganrolleri9198]

This video was very helpful for my understanding of the different types of validity. It is pretty confusing and seems as if they can get mixed up easily but you did a great job explaining them!

[@alannabergherm8046]

It was interesting to learn about the various types of validity! It was helpful to have them broken down into key terms.

[@laurenomalley9063]

It was really helpful to hear your explanations of validity and reliability because I always get them confused!

[@austiniturbe4495]

Great video Dr. Goodin!

[@coreycollier2063]

It nice to know the common ground that needs to be established in order to have consistent, reliable tests.

[@mikestatz5098]

reading about the different validities was way more confusing than you made it seem! Thanks for the clarity!

[@lucamarin8565]

I always got the different types of validity wrong great video in clarifying them

[@bojak76]

In swimming, we would test our back squat and I never understood why. Seeing now the concurrent validity, it makes sense that it can translate to leg-power in the push-off from the wall.

[@SuperTroyAustin]

Validity is definitely confusing, but you explained it very well!

[@justiniane.michaels5833]

Hey man I love your videos! But just a word of friendly advice - the background music is too loud and distracting. Thank you man and I appreciate all your amazing content!

[@madelinehernandez8838]

I have heard of validity before but I did not know there were different types of validity. Such as construct, face, content, criterion-referenced, concurrent, predictive, and discriminant.

[@Adam.gates_]

It makes sense that a 1RM test is safer than a 3RM test, given that you only need to focus on max effort and proper technique throughout one rep rather than three.

[@aribhalla9820]

After watching this video, it makes sense why simply testing repetition of pushups does not accurately measure someone's entire upper body strength. Definitely makes me feel better about not being able to do a bunch of consecutive push-ups lol

[@strivemore]

Good video lad

[@DrJacobGoodin]

Thanks my friend!

[@strivemore]

@@DrJacobGoodin Thanks for the response!Huge question I have for the cscs practical section, questions that involve: "baseball player has 80th percentile bench press, 50th percentile aerobic endurance, 90th percentile push up test" what should athlete work on in pre season? Any tips for those type questions?

[@DrJacobGoodin]

@@strivemore Yeah that's a great question. There will most likely be several questions in that format, and my best advice is to study the normative tables from the textbook so that you can a) identify which scores are the lowest for that level of athlete, and b) pair up the testing results with the demands of the sport. In your example, it's hard to say because baseball athletes don't need a ton of aerobic endurance, and 80th and 90th percentile is very high already. Usually I've seen questions where one test that was important for the sport was low, but you wouldn't know that unless you were familiar with what a good score would be. A bit long-winded but I hope that helps!

[@strivemore]

@@DrJacobGoodin That helps soooo much! Its crazy because I took it in August and failed the applied portion, and you made these vids in November! good timing to learn from them for my next try! Seriously you are awesome!

[@myawilliams8357]

I think performance testing is very important. All the key points and terms just makes sure that the athlete can only improve on their skill

[@millermoss1]

Hey Dr. Goodin, I can't differentiate between construct and content validity. The example of a questionnaire makes sense for content validity, but the other example you gave about the agility v COD tests sounds a lot like construct validity. How does that example differ from the local muscular endurance vs. muscular strength example given for the upper body for construct validity? Thank you!

[@DrJacobGoodin]

This short set of slides courtesy of the UNL psych dept does a better job explaining than I did in the video if you want to check them out: psych.unl.edu/psycrs/451/e2/fccvalidity.pdf

[@basketballyouthdevelopment3247]

Hello Dr. Jacob following your videos for the past 3 months if possible can you please post a video in CSCS chapter 8 psychology of Athletic Preparation and Performance Appreciate your work and thank you.

[@DrJacobGoodin]

I'm so pumped that these videos have been helpful to you my friend. The plan is to continue where I left off when our Spring semester picks back up. It starts in March this year (due to COVID) but I'll be back at it. The goal is to finish the rest of the chapters by May or June. Until then, I have content for some other courses I've been working on. But stay tuned!

[@basketballyouthdevelopment3247]

@@DrJacobGoodin Already I have saw your 1 of the video on regarding Inverted u theory & RFD but rite it’s not available if possible can you please share that content because my CSCS exam is on FEb 19th I suggested your channel to many of friends because your examples are really sticking inside the mind so easy to recall it. Thanks

[@CurbMarsh7]

This is great! I have a slight confusion with differentiating between Interrater and Intrarater because between and within raters kinda feels like the same thing to me. I feel like they both would decrease test reliability? Does anyone have any tricks they used to help them separate the two? Thanks in advance

[@DrJacobGoodin]

Excellent question-I find myself sometimes forgetting which is which! Inter- is a prefix that means between, and intra- is a prefix which means within. Inter-rater reliability means that two or more raters are reliable when compared to each other. Intra-rater reliability means that a single rater is reliable with his/her own measurements. And both of them do contribute to overall reliability, as you correctly surmise.

[@bigred77573]

What would be your definition for convergent validity?

[@clarisamarin7284]

It's interesting that emotional maturity is also a factor in the reliability in a test.
