## Method

**Participants**

- Is the sample size adequate to find the effect? Are power analyses mentioned?
- Are the participants representative of the population?
- Are there equal numbers of males and females?
- Are there a range of socioeconomic strata and ethnicities?
- For this class, is the diagnosis confirmed?

- Where were the participants obtained from, and are they a biased sample?
- If it is an experimental design, was true random assignment done (random number generator)?

**Measures**

- Are the measures widely used in the field?
- Are the measures reliable and valid?
- Are they appropriate for the group or age being studied (i.e. not too difficult or too easy)?
- Are all the measures explained adequately?
- Do the measures seem to have face validity -- that is, do they measure what the authors say the variable of interest is in an adequate fashion?
