`Shogren.Rd`

Data from a systematic review by Shogren et al. (2004) on the effects of choice-making interventions. These data were compiled and re-analyzed in Pustejovsky (2015). The variables are as follows:

`Study`

. An ID for each study in the systematic review.`Case`

. Case Pseudonym provided by the authors.`Measure`

. Type of behavior observed as the outcome measure`Phase`

. Phase indicator, baseline phase is "No Choice" and treatment phase is "Choice."`Percentage`

. For those outcomes measured as percentage, outcomes value.`NA`

for count outcomes.`Observed`

. For those outcomes measured as count, outcome value.`NA`

for percentage outcomes.`Possible`

. For counts out of a maximum, lists the maximum value.`Recording_procedure`

Recording procedure. CDR = "Continuous Duration Recording", EC = "Event Counting", "MTS = "Momentary Time Sampling", and PIR = "Partial Interval Recording."`Session_length`

. Length of the observation session in minutes.`interval_length`

. Length of the observation intervals for data observed using MTS or PIR.`outcome`

. Value for the outcome for all outcome types.`direction`

. Direction of therapeutic improvement for the outcome.
