Feasibility and efficacy of an intervention to reduce secondhand smoke exposure among infants discharged from a neonatal intensive care unit.

OBJECTIVE: To examine the feasibility and efficacy of a hospital-based, motivational intervention to reduce secondhand smoke exposure (SHSe) with mothers of infants in a neonatal intensive care unit (NICU). STUDY DESIGN: One-hundred and forty-four mothers with infants ( ≤ 1500 g at birth or ≥ 12 h ventilation) in a NICU who reported a smoker in the household were randomized to two sessions of motivational interviewing (MI) conducted in the hospital, usual care (UC) or usual care-reduced measurement (UC-RM); follow-up occurred at 1- and 6-months post discharge. RESULT: For households that did not have a total smoking ban at baseline, 63.6% of those in the MI group instituted a ban by 1-month post discharge compared with 20% of the UC group, P<0.02. Six months post discharge, fewer smoking bans were noted in the UC-RM group relative to MI and UC, P<0.01. CONCLUSION: A need for SHSe interventions among NICU parents exists and initial evidence suggests MI can impact SHSe after discharge.

Motivational interviewing with cocaine-dependent patients: a pilot study.

A brief motivational interviewing (MI) intervention was evaluated within the context of an outpatient, cocaine-detoxification program. MI was hypothesized to assist patients in completing the detoxification program and to improve outcomes during subsequent treatment. Participants (N = 105) were randomly assigned to MI or to detox-only conditions. Results indicated that although participants completed the detoxification program at equal rates, completers who received MI increased use of behavioral coping strategies and had fewer cocaine-positive urine samples on beginning the primary treatment. MI patients with lower initial motivation were more likely to complete detoxification.

Fluoxetine treatment of cocaine-dependent patients with major depressive disorder.

Sixty-eight male and female individuals with both DSM-IV diagnoses of cocaine dependence and major depressive disorder were randomly assigned to one of two medication conditions (placebo vs. 40 mg per day) as part of a double-blind, placebo-controlled clinical efficacy trial of fluoxetine for the treatment of this dual diagnosis. During the 12-week outpatient treatment phase all participants also received individual cognitive-behavioral psychotherapy targeting both cocaine use and depression. Depressive symptoms remitted as a function of time in treatment, with no significant medication effects found. Fewer cocaine positive urines were found during the first 6 weeks of treatment in the placebo group compared with the 40-mg group. Cocaine use and depressive symptoms during treatment were significantly correlated. The findings fail to support the role of fluoxetine for treatment of cocaine use and depression in dually-diagnosed patients.

Naltrexone and relapse prevention treatment for cocaine-dependent patients.

A double-blind, placebo-controlled clinical trial examining the joint action of naltrexone (NTX) in combination with relapse prevention (RP) therapy for the treatment of cocaine dependence was conducted. Eighty-five participants who achieved initial abstinence during the intake evaluation and detoxification phase of the study were randomized into 1 of 4 combined NTX (0 vs. 50 mg) by therapy (RP vs. Drug Counseling) experimental conditions for the 12-week outpatient treatment phase of the study. A random effects regression model to test for group differences on percentage of cocaine-positive urines indicated a significant time by medication by therapy interaction, suggesting less cocaine use over time among subjects receiving RP-50 mg than those in the other conditions. No differences were found for retention or time until first cocaine-positive urine. Naltrexone was well tolerated by participants, with acceptable rates of medication compliance observed. Treatment integrity measures confirmed successful manipulation of the psychotherapy. These results are consistent with the notion that substance use in dependent patients can be reduced with a combination of coping skills training and pharmacologic treatments.

Cocaine dependence with and without comorbid depression: a comparison of patient characteristics.

This study compared depressed cocaine dependent patients (CD, N=50) with patients who were cocaine dependent only (CO, N=101) on pre-treatment psychiatric symptomatology, substance use, and psychosocial functioning. Results indicated that the CD group had more overall distress and poorer psychiatric functioning than the CO group. CD individuals scored higher on all subscales of the SCL-90-R, had a higher prevalence of antisocial personality disorder, reported higher craving for cocaine, lower self-efficacy to refrain from drug use, and lower perceived social support. These findings support the need for more intensive treatment approaches for dually-diagnosed patients.

Postpartum return to smoking: staging a "suspended" behavior.

Two hundred fifty-six pregnant women who had quit smoking were classified into the precontemplation (PC), contemplation (C), preparation (PA), or action (A) stages of change for postpartum smoking cessation based on a 3-item algorithm assessing personal goals, self-efficacy, and smoking behavior. Logistic regression and event history analyses indicated group differences in return to smoking at 6 weeks and 3, 6, and 12 months postpartum. The percentage of women who returned to postpartum smoking was highest in the precontemplation stage and decreased with each subsequent stage, that is, at 6 weeks 83% of PCs, 64% of Cs, 35% of PAs, and 24% of As had returned to smoking. Results lend support for the stages of change for postpartum smoking abstinence. Stage-based interventions may be developed to assist women in maintaining abstinence postpartum.

Pregnancy smoking cessation: a case of mistaken identity.

This study examined the process of change in pregnancy smoking cessation, using the stages and processes of change from the Transtheoretical Model, to compare women who stopped smoking during pregnancy with women who were in the process of smoking cessation, but were not pregnant. Differences in smoking cessation process activity and abstinence self-efficacy were hypothesized between the pregnant and nonpregnant groups of women. Study participants were 89 pregnant women who quit smoking, 28 nonpregnant women in the action stage of smoking cessation, and 92 nonpregnant women in the preparation stage. The Smoking Cessation Processes of Change Scale and the Smoking Abstinence Self-Efficacy Scale served as dependent measures. One-way MANOVA and follow-up Newman-Keuls comparisons indicated significant differences between pregnant and nonpregnant women in their levels of process activity and self-efficacy. Pregnancy smoking cessation differed dramatically from the process of nonpregnancy smoking cessation. Pregnant quitters were not engaging in experiential and behavioral processes at levels associated with the action stage of change. Low levels of process use and high efficacy indicated an externally (for the baby) motivated stopping rather than an internal, intentional process of change, which may account for high relapse rates postpartum.
