Brief Alcohol Intervention for Adolescents Who Have Attempted Suicide

Adolescent Drinking Questionnaire (ADQ). The ADQ is a 6 item self-report measure assessing drinking frequency (days per month), quantity (drinks per occasion), frequency of high-volume drinking (≥ 5 drinks per occasion), and frequency of intoxication (feeling "drunk" or "very, very high"), over the past month.

Timeline Follow-back Interview (TLFB). The TLFB is a widely-used research and clinical assessment tool with good reliability and validity for various groups of individuals with alcohol use problems. The TLFB collects alcohol and drug consumption information using a calendar format with temporal cues to assist in recall of days when alcohol and drugs were used, and can be used to simultaneously recall other behaviors, such as suicidal ideation and attempts. The TLFB will be conducted using the prior 30 days at baseline and each follow-up.

Columbia-Suicide Severity Rating Scale (C-SSRS). The C-SSRS assesses the range of suicidal behavior including preparatory acts, aborted attempt and interrupted attempt, and passive and active suicidal ideation, as well as intensity of ideation. To avoid redundancies in measures, we will not administer the intensity of ideation section to the participant, as some of that construct is captured by the SIQ. At follow-up, suicidality will be assessed only since the last assessment.

Suicide Ideation Questionnaire (SIQ). The SIQ is a 30 item self-report instrument that assesses suicidal ideation in adolescents over the past month. Items are rated on a 7-point Likert scale (0=I never had this thought, to 6=almost every day). Coefficient alpha internal consistency measures for the SIQ have been reported at 0.97 as well as good construct validity.

Drug Use Questionnaire (DUQ). The DUQ assesses the number of days adolescents used substances over the past 30 days including nicotine, marijuana, cocaine, LSD, PCP, inhalants, etc. Internal consistency in one study sample was .75 (alpha = .80 when inhalants was dropped). Test/retest for mean number of days each substance was used was .83 from 3 to 6 month follow-up and .94 from 6 to 12 month follow-up.

Brief Situational Confidence Questionnaire (BSCQ). The BSCQ is an eight item self-report instrument used to assess confidence in one's ability to resist the urge to use alcohol or other substances. Responses are provided on 10-point Likert scales (i.e., 10% increments, from 0%=not at all confident to 100%=completely confident). The Cronbach's alpha coefficient was 0.85 in one study.

Comprehensive Effects of Alcohol (CEOA). The CEOA is 38 items and assesses positive and negative expected effects of alcohol and has demonstrated adequate internal consistency, temporal stability and construct validity.

Opinions About Alcohol Use (OAAU). The OAAU is a two item self-report measure assessing the importance and confidence in reducing alcohol use. In addition to baseline and 3 month follow-up, this measure will be administered post-intervention to all participants randomized to the intervention, to assess for within session changes.
