| CIDI 3.0 bipolar screening scales scoring |
| The complete set of 12 questions takes approximately 3 minutes to complete. |
| The scale has 12 questions |
| NOTE: To "endorse" = answer "yes," in a yes-no response. |
| 2 stem questions: question 1 and 2 |
| Respondents who fail to endorse either of these first 2 questions are skipped out of the remainder of the question series. |
| 1 criterion B screening question: question 3 |
| Respondents who fail to endorse this question after endorsing 1 of the first 2 stem questions (above) are skipped out of the remainder of the question series. |
| Respondents who do endorse this question are then administered the 9 additional symptom questions. |
| NOTE: In a general population sample, it can be expected that as many as 90% of the sample will skip out by the end of this third question. |
| 9 criterion B symptom questions |
| Each of the 9 symptom questions are administered. |
| NOTE: The first question in this group is asked only if the first stem question (above) is endorsed; if this scenario occurs, then only the 8 remaining symptom questions would be administered. |
| The risk of bipolar disorder is roughly as follows, depending upon the number of questions endorsed: |
| Very high risk (80% or more) | 9 questions with positive endorsement |
| High risk (50 to 79%) | 7 to 8 questions with positive endorsement |
| Moderate risk (25 to 49%) | 6 questions with positive endorsement |
| Low risk (5 to 24%) | 5 questions with positive endorsement |
| Very low risk (less than 5%) | 0 to 4 questions with positive endorsement |
| CIDI-based bipolar disorder screening scale |
| I. Stem questions |
- Euphoria stem question: Some people have periods lasting several days or longer when they feel much more excited and full or energy than usual. Their minds go too fast. They talk a lot. They are very restless or unable to sit still and they sometimes do things that are unusual for them, such as driving too fast or spending too much money. Have you ever had a period liked this lasting several days or longer? (If this question is endorsed, the next question [the irritability stem question] is skipped and the respondent goes directly to the criterion B screening question.)
|
- Irritability stem question: Have you ever had a period lasting several days or longer when most of the time you were so irritable or grouchy that you either started arguments, shouted at people, or hit people?
|
| II. Criterion B screening question |
- People who have episodes like this often have changes in their thinking and behavior at the same time, like being more talkative, needing very little sleep, being very restless, going on buying sprees, and behaving in ways they would normally think are inappropriate. Did you ever have any of these changes during your episodes of being excited and full of energy/very irritable or grouchy?
|
| III. Criterion B symptom questions |
Think of an episode when you had the largest number of changes like these at the same time. During that episode, which of the following changes did you experience? - Were you so irritable that you either started arguments, shouted at people, or hit people? (This first symptom question is asked only if the euphoria stem question [#1 above] is endorsed.)
- Did you become so restless or fidgety that you paced up and down or couldn't stand still?
- Did you do anything else that wasn't usual for you – like talking about things you would normally keep private, or acting in ways that you'd usually find embarrassing?
- Did you try to do thing that were impossible to do, like taking on large amounts of work?
- Did you constantly keep changing your plans or activities?
- Did you find it hard to keep your mind on what you were doing?
- Did your thoughts seem to jump from one thing to another or race through your head so fast you couldn't keep track of them?
- Did you sleep far less than usual and still not get tired or sleepy?
- Did you spend so much more money than usual that it caused you to have financial trouble?
