Types of self-report measures (2)

2) prospective
Retrospective self-report example
Insomnia Severity Index
Retrospective self-report advantages (5)
1) easy to administer
2) fairly comprehensive
3) requires minimal explanation
4) inexpensive
5) sensitive to change (for treatment outcome studies)
Retrospective self-report disadvantages (3)
1) relies on an average
2) influenced by saliency and recency
3) pre-post study designs - open to experimental demand
Prospective self-report example
Sleep diary
Prospective self-report advantages (5)
1) does not require concept of average
2) applies to only one time point
3) night to night variability
4) get a sense of circadian phase: owl or lark
5) useful for collecting data on effect of naps, alcohol

2) based on subjective impression
3) difficult to get compliance: time locked data

sleep onset latency
WASO
wake after sleep onset
EMA
early morning waking
TST
