Participants at the last meeting of the Society for the Improvement of Psychological Science developed a list of >100 such datasets with some metadata such as topic, country, total number of participants, etc. The list is currently a collaborative wiki open to editing by anyone. List of open psychology datasets and aggregators Outside of psychology, there ...

At least the 100 number seems based on the CDC parenteral dose conversion: (Fentanyl has poor oral bioavailability, so it's not intended to be used that way.)

Yes, the General Assessment of Functioning (GAF) score can be used for all psychiatric disorders. The GAF is not commonly used now as the DSM V has opted for the WHODAS 2.0 instead of GAF. There were fundamental problems with GAF including poor reliability with people who were less trained, cross-cultural variations and symptom severity tended to influence ...

Prefrontal cortex is most closely associated with the group of cognitive functions termed "executive function" - measures of executive function do not measure prefrontal cortex per se because (almost all) brain functions are not simply localized to one area, but one would expect major lesions of the prefrontal cortex to impair executive function, as would ...

In the measures subsection of the methods section in the paper you refer to (Gifford et al, 2004), you can see that Gifford et al. (2002) is cited when referring to the AIS questionnaire. However, I cannot seem to find this paper titled "Combining Bupropion SR with acceptance-based behavioral therapy for smoking cessation: Preliminary results from a ...

Questionnaires and measurement scales typically take a lot of revision and validation. Otherwise, it is very common that you measure things you don't intend to measure, are missing relevant options, or omit critical factors entirely. I'd recommend some piloting and to use existing and validated measures whenever possible. Some of your items sound ...

Howell is just making a distinction between types of independent variables (predictors in a regression context): continuous variables versus categorical ones. In the case of categorical variables, like "Treatment A" and "Treatment B", your regression equation will contain variables that contrast between Treatment A and Treatment B - often this is by "dummy ...

Although I don't know the answer, I think it would be important to explain what you exactly wish to do with the re-test? If you solely wish to know how reliable the score is, you could do the test on day 1 and the re-test on day 2? The longer the time, the higher the chance that a person's life is subject to change (e.g., the loss of relatives, or medical ...

Correction on Education "intelligence is dependent on ... education." This is incorrect. Intelligence is a stable trait over time (Gottfredson, 1998). The correlation between education and intelligence is that on average, people who attain higher levels of education have higher levels of intelligence (Gottfredson, 1997). We wouldn't expect someone with an ...

Well, in a recent debate whether Big Five is... ahem... sexist, this was mentioned, which pertains your question: There’s another flaw when it comes to taking Big Five personality tests online. The online versions of the Big Five traits inform people of negative character traits, without explaining that the positivity or negativity of all characteristics ...

My Answer In this scenario, the unrestricted group is the population of individuals who are in the selection process. For example, Held and Foley (1994, Table 3) https://conservancy.umn.edu/bitstream/handle/11299/116989/v18n4p355.pdf shows the consequences of different selection ratios on validity coefficient estimations. To summarize, the unrestricted ...

I think what we call ideologies may be too varied across time and locations to capture in a questionnaire format. If you go one level more specific, to something like support of religion, free market, or moral situations, these may be more reliably and universally measurable. One feature that feels universal is what constitutes a moral violation. Schwartz, ...
