Description / Type of Assessment:

SCQ-H is a 22-item self-reported questionnaire. For each of these 39 items, respondents consider the situation described and indicate how confident they are that they would be able to resist the urge to use heroin in that situation. Anchored on a six-point scale, response options range from 0% (not at all confident) to 100% (very confident), with mid-range options including 20%, 40%, 60% and 80% confidence levels.

Primary use / Purpose:

The SCQ-H was developed to assess a client's perceived ability to cope effectively with heroin in high risk situations in everyday life.

Domains measured / Life Areas / Problems Assessed:

Items included on the SCQ were selected and adapted from the pool of 100 items included on the Inventory of Drinking Situations, which were chosen to cover the eight categories of high-risk relapse situations that Marlatt and Gordon (1980) identified as being common alcohol relapse situations:
Negative emotional states
Negative physical states
Positive emotional states
Testing Personal Control
Urges and Temptations
Interpersonal conflict
Social Pressure
Positive Social Situations



Administration / Completion Time:

Not reported.

Scoring Procedures:

Average confidence scores are calculated for each of the eight categories and overall SCQ-H scores are calculated by averaging confidence scores across all eight areas. In addition to the separate subscale scores, profiles can be constructed of the client's confidence in resisting heroin use based on scores on the eight categories.

Scoring Time:

Not reported.

Practicability / usefulness:

The Situational Confidence Questionnaire - Heroin assesses heroin-related self-efficacy (that is, how confident a client is that he/she will be able to resist to use heroin in the future). These profiles obtained may help the client and the therapist identify areas of strength and areas of vulnerability in resisting urges to drink. There is initial evidence supporting the validity and reliability of the SCQ-H.Further validation studies are needed to demonstrate adequate psychometric properties in different populations, as well as the ability of the SCQ-H to measure change over time.
