Table 2.
Subtask Completion Scores |
Each of the 8 subtasks is assigned one of the following scores. |
1 = Complete/Efficient. Assigned when subtask completed accurately and efficiently. |
2 = Complete/Inefficient. Assigned when subtask completed in a way that the overall DOT goal can be met but subtask completion is inefficient (e.g., pretends to take pill too early, carries items to front door in hand rather than picnic basket, gathers more items than needed for recipe, searches multiple locations for items). |
3 = Incomplete/Inaccurate. Assigned when subtask is left incomplete (e.g., fails to pack gathered item in picnic basket, fails to pretend to take pill, fails to remove heating pad from microwave) or is completed inaccurately (e.g., fails to retrieve enough change for bus, pretends to take wrong pill, grabs reading material other than magazine for bus ride). |
4 = Never Attempted. Assigned when subtask failed to be initiated. |
|
Total Accuracy Score |
Summation of the subtask completion scores (see above) for each of the 8 subtasks (range = 8 – 32). |
|
Task Sequencing Score |
Total number of the six activities below correctly sequenced (range = 0 – 6). |
1. Heating pad started as one of first four activities. |
2. Picnic basket retrieved as one of first four activities. |
3. Cost of bus route determined prior to first attempt at retrieving change. |
4. Recipe read prior to retrieving food items. |
5. Dramamine pill taken near end. (Dramamine pill is taken too early if another subtask is initiated after the Dramamine pill is taken other than the exit subtask, or another subtask is completed after the Dramamine pill subtask other than the picnic basket subtask, heating pad subtask, or exit subtask.) |
6. Picnic basket moved to front door as one of last two activities. |
|
Examiner Rating Scores |
Averaged across both examiners, range = 1 - 5. |
Task Quality: Characterizes overall rating for how well the DOT was carried out by the participant. |
Goal Directedness: Characterizes overall rating for how well the participant remained on task and was able to use the list of tasks to quickly and efficiently move from one subtask to another. |
5-Point Likert Rating Scale: 1=excellent 2=very good 3=good 4=fair 5=poor |
