Protocol - Expectancies - Alcohol, Cigarette Smoking, and Other Smoking - Illegal Stimulant Drugs

Add to My Toolkit
Description:

The Stimulant Effect Expectancy Questionnaire (SEEQ) is a modification of the Cocaine Effect Expectancy Questionnaire that assesses stimulants in general, rather than cocaine only. Subjects are asked to answer 71 questions regarding the stimulant with which they are most familiar and according to their beliefs about the stimulant drug they "know best." The SEEQ assesses 5 scales - Global Positive Effects, Global Negative Effects, General Arousal, Anxiety, and Relaxation with Tension Reduction. A shorter version of the SEEQ contains 46 items across the same 5 scales (4–14 items per scale).

Protocol:

The following pages contain statements about the effects of stimulants, including cocaine and amphetamines (crystal meth, speed). Read each statement carefully and respond according to your own personal thoughts, feelings, and beliefs about stimulants now. We are interested in what you think about stimulants, regardless of what other people might think.

Whether or not you have had actual experiences with stimulants yourself, you are to answer in terms of your beliefs about stimulants. It is important that you respond to every question. There are no right or wrong answers.

A. Which stimulant drug do you have the most experience with or knowledge about? (check a box)

[ ] COCAINE (including crack)

[ ] AMPHETAMINES (including crystal meth and speed)

Please fill out the following questions according to your beliefs about the stimulant drug you know best. PLEASE BE HONEST. REMEMBER, YOUR ANSWERS ARE CONFIDENTIAL. RESPOND TO THESE ITEMS ACCORDING TO WHAT YOU PERSONNALLY BELIEVE TO BE TRUE ABOUT A MODERATE AMOUNT OF STIMULANTS - HOWEVER YOU DEFINE MODERATE.

Scoring Procedure and Interpretation

The 46 items of the Stimulant Effect Expectancy Questionnaire (SEEQ) comprise the following 5 scales (Aarons et al., 2001):

(1) Global Positive Effects: items 2, 10, 22, 23, 25, 28, 37, 44, 45, and 46

(2) Global Negative Effects: items 3, 8, 9, 27, 29, 32, 33, 34, 35, 36, 38, 39, 40, and 43

(3) General Arousal: items 6, 12, 14, 15, 17, 20, 21, and 42

(4) Anxiety: items 1, 4, 5, 13, 16, 18, 19, and 41

(5) Relaxation and Tension Reduction: items 7, 11, 24, and 31

The score for each scale is calculated by averaging the item scores, i.e., totaling the item scores and dividing by the number of items in the scale. Each item is scored on a 1 to 5 scale (Disagree Strongly = 1 and Agree Strongly = 5). Of note, items 26 and 30 are not scored. The scoring scheme reflects factors identified in the original publications. Factor structure may differ in individual studies.

Specific Instructions:

The Substance Abuse and Addiction Working Group acknowledges that the following questions may gather sensitive information relating to the use of substances and/or illegal conduct. If the information is released, it might be damaging to an individual’s employability, lead to social stigmatization, or lead to other consequences.

Most researchers assure confidentiality as part of their informed consent process, as required by their institutional review boards. Further assurance of confidentiality may be obtained by applying to the National Institutes of Health (NIH) for a Certificate of Confidentiality, which helps researchers protect the privacy of human research participants. The procedures for the Certificate of Confidentiality can be found at the Grants Policy website of the NIH: http://grants1.nih.gov/grants/policy/coc/index.htm.

Selection Rationale

The 46-item Stimulant Effect Expectancy Questionnaire (SEEQ) has been determined to be psychometrically sound. It has generally good internal consistency and has moderate test-retest reliability.
