Validity refers to the extent to which a measure adequately represents the underlying construct that it is supposed to measure. Empirical assessment of validity examines how well a given measure relates to one or more external criterion, based on empirical observations. This type of validity is called criterion-related validity, which includes four sub-types: convergent, discriminant, concurrent, and predictive validity.

Sure. Despite no particular rules, the following are the points you should try to avoid:
• long complex questions
• double negatives
• double-barreled questions
• jargon or abbreviations
• culture-specific terms
• words with double meanings
• leading questions
• emotionally loaded words

You are right. There are 3 major types of validity, namely content validity, criterion validity and construct validity.

It shows the extent to which it assesses what it is expected to assess.

Dear Dr. Mel, may I ask another question about CSO? I wonder if the CSO scheme only serves as a means of punishment.

Hi everyone! It is well recognized that crime and delinquency of young people place considerable economic loss on society, from an economic standpoint. I am trying to find an appropriate way to estimate these costs in Hong Kong. Appreciate it if you could give me some advice to calculate. Or maybe provide me with some practical examples.

Following your previous suggestion, I have searched some theories to explain youth delinquency and the absence of parental supervision after school hours and found Hirschi’s social control theory. Yet, how to link youth’s behavior to social control is a huge challenge for me (I do believe in “the person in environment” theory). Grateful if you help me with it!

Hi there. I am conducting a program evaluation of our services for juvenile crime. Yet, surprisingly I found that the most likely time for a juvenile to commit a crime is weekdays, instead of weekends. It doesn’t make sense to me… Is there anyone who could give me a hand?

Hi, I realized that it seems the concept “outcome” is different from the term “output”. Taking the grandparent training project as an example, what is the “outcome’ referable?

I have designed a large-scale survey about the life satisfaction of low-income families in Hong Kong. Is it appropriate to use the electronic survey through mobile phones?
