Refers to whether a piece of research is useful, practical, applicable: can it be accurately generalised to a wide population?

Usefulness - evaluation points?
1. Internal Validity - Face validity (is it measuring what it intends to measure?) or construct validity (is the definition in the research actually accurate?) 2. External Validity - Ecological Validity, Population Validity or Temporal Validity.

Usefulness - evaluation points?
3. Nomothetic - refers to a theory which can be assumed to be a general law or principle of behaviour. The more "exceptions to the rule" there are, the less it's going to be useful.

Reductionism - what does it mean?
Reductionism refers to the breaking down of complex phenomenon into smaller components. Essentially, the more simplistically a behaviour is explained, the more reductionist the theory.

Effectiveness - what does it mean?
he extent to which something brings about an effect, usually a positive one.
5 of 13
Effectiveness - evaluation points?
Who is it effective for? To what extent does it make a difference? Is it time and cost effective?

Appropriateness -what does it mean?
Appropriateness refers to the extent to which something is suitable, usually in terms of population or situation.
7 of 13
Appropriateness - evaluation points?
Look at the population - does it suit them? e.g. depressed patients losing motivation may make it hard to get them to commit to a cognitive therapy. Does it solve the cause or the symptoms?

Validity - what does it mean?
Validity refers to the extent to which a measure is measuring what it intends to, or in other words, it refers to extent to which it reflects the reality that it claims to represent.
9 of 13
Validity - Internal validity evaluation points?
Face validity=extent to which it measures what it's meant to be; Construct validity - is the IV or DV appropriate for the concept being investigated? e.g. stress hasn't been defined, show how can it be measured?; Concurrent validity = supported?
10 of 13
Validity - External validity evaluation points?
Ecological validity, population validity, temporal validity.
11 of 13
Reliability - what does it mean?
refers to how consistent a study or measuring device is.
12 of 13
Reliability - evaluation points?
Control over confounding variables, standardisation, population and ecological validity (if low then real life cannot be expected to be consistent with results), subjectivity.
