Reliability and Validity of the Newton Screen for Alcohol and Cannabis Misuse in a Pediatric Emergency Department Sample.

OBJECTIVES: To determine the test-retest reliability, concurrent, convergent, and discriminant validity of a recently devised screen (the Newton screen) for alcohol and cannabis use/misuse, and its predictive validity at follow-up. STUDY DESIGN: Adolescents, 12-17 years old (n = 4898), treated in 1 of 16 participating pediatric emergency departments across the US were enrolled in a study as part of a larger study within the Pediatric Emergency Care Applied Research Network. Concurrent and predictive validity (at 1, 2, and 3 years of follow-up) were assessed in a random subsample with a structured Diagnostic and Statistical Manual of Mental Disorders-based interview. Convergent validity was assessed with the Alcohol Use Disorders Identification, a widely used alcohol screening measure. RESULTS: The sensitivity of the Newton screen for alcohol use disorder at baseline was 78.3% with a specificity of 93.0%. The cannabis use question had a baseline sensitivity of 93.1% and specificity of 93.5% for cannabis use disorder. Predictive validity analyses at 1, 2, and 3 years revealed high specificity but low sensitivity for alcohol and high specificity and moderate sensitivity for cannabis. CONCLUSIONS: The Newton screening instrument may be an appropriate brief screening tool for use in the busy clinical environment. Specificity was high for both alcohol and cannabis, but sensitivity was higher for cannabis than alcohol. Like other brief screens, more detailed follow-up questions may be necessary to definitively assess substance misuse risk and the need for referral to treatment.

Understanding Suicidal Ideation in Latino/a Adolescents Living in Puerto Rico.

Puerto Rican adolescents, as well as other Latinos/as, have been identified at higher risk for suicidal ideation and attempts compared to other ethnic groups. However, research designed to better understand suicidality among Puerto Rican adolescents is rare. OBJECTIVE: A socio-cognitive vulnerability model of suicidal ideation was tested in adolescents living in Puerto Rico. METHOD: Multiple group path analyses were performed to assess the effect of self-reported socio-environmental and vulnerability factors on suicidal ideation, by sex, in 233 students from the metropolitan area of San Juan, Puerto Rico. RESULTS: Overall, the model explained a large amount of the variance in suicidal ideation (r2 = .59 for females and r2 = .48 for males). Depressive symptoms had the strongest total effect on suicidal ideation for both sexes (r = .69 for females and r = .53 for males) and negative life events were the most salient socio-environmental factor. Hopelessness had a direct effect on suicidal ideation for males only. Externalizing behaviors had a direct effect on suicidal ideation for both males and females, but it was particularly strong for females. CONCLUSION: Results support the mediating role of vulnerability factors and the differential importance of socio-environmental and vulnerability factors in understanding suicidal ideation among Puerto Rican adolescents. The relevance of exploring different developmental paths to suicidal ideation, separately by sex, is discussed.

Development of a treatment protocol for Puerto Rican adolescents with suicidal behaviors.

Adolescents in Puerto Rico are at an increased risk for suicide attempts, though evidence-based treatments specifically for this group have not been tested. The current study was designed to develop and pilot test a culturally sensitive, manualized outpatient treatment for Puerto Rican adolescents who have experienced a suicidal crisis. The study was divided into phases. Phase 1 consisted of developing a socio-cognitive behavioral treatment for suicidal behavior. Phase 2 tested the treatment protocol in an open trial with 11 (6 male and 5 female) Puerto Rican adolescents. Active treatment had an approximate duration of 3-6 months. An initial assessment, process measures, and posttreatment assessment were completed with each participant to measure treatment feasibility as well as suicidality, symptoms, and risk factors. Participants were very satisfied with treatment and reported relevant clinical benefits. The retention rate was 73% (8 out of 11). For those who completed the treatment protocol, the goal of reducing further suicide risk was achieved; 2 showed reliable clinical changes in suicidal ideation, while 6 maintained low levels during treatment. All treatment completers had either a partial or total remission of their pretreatment diagnosis and half had reliable improvements in at least 1 risk factor. A theory-driven treatment protocol was developed according to patient's needs, but further research is needed to continue its development and to explore its efficacy.

A randomized clinical trial of a brief motivational intervention for alcohol-positive adolescents treated in an emergency department.

We tested whether a brief motivational interview (MI) would reduce alcohol-related consequences and use among adolescents treated in an emergency department (ED) after an alcohol-related event. Patients aged 13 to 17 years (N = 152) with a positive blood alcohol concentration (BAC) by lab test or self-report were recruited in the ED and randomly assigned to receive either MI or standard care (SC). Both conditions resulted in reduced quantity of drinking during the 12-month follow-up, whereas alcohol-related negative consequences were relatively low and stayed low at follow-up. Adolescents who screened positive for problematic alcohol use at baseline reported significantly more improvement on 2 of 3 alcohol use outcomes (average number of drinking days per month and frequency of high-volume drinking) if they received MI compared with SC. We conclude that brief interventions are recommended for adolescents who present to an ED with an alcohol-related event and report preexisting problematic alcohol use.
