Motivational enhancement and self-help treatments for problem gambling.

Two brief treatments for problem gambling were compared with a waiting-list control in a randomized trial. Eighty-four percent of participants (N?=?102) reported a significant reduction in gambling over a 12-month follow-up period. Participants who received a motivational enhancement telephone intervention and a self-help workbook in the mail, but not those who received the workbook only, had better outcomes than participants in a 1-month waiting-list control. Participants who received the motivational interview and workbook showed better outcomes than those receiving the workbook only at 3-and 6-month follow-ups. At the 12-month follow-up, the advantage of the motivational interview and workbook condition was found only for participants with less severe gambling problems. Overall, these results support the effectiveness of a brief telephone and mail-based treatment for problem gambling. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Using Behavioral Theories of Choice to Predict Drinking Outcomes Following a Brief Intervention.

Behavioral theories of choice predict that substance use is partly a function of the relative value of drugs in relation to other available reinforcers. This study evaluated this hypothesis in the context of predicting drinking outcomes following an alcohol abuse intervention. Participants (N=54, 69% female, 31% male) were college student heavy drinkers who completed a single-session motivational intervention. Students completed a baseline measure of substance-related and substance-free activity participation and enjoyment. Only women showed a significant reduction in drinking at the 6-month follow-up, and the ratio of substance-related to substance-free reinforcement accounted for unique variance in their drinking outcomes. Women who at baseline derived a smaller proportion of their total reinforcement from substance use showed lower levels of follow-up drinking, even after the authors controlled for baseline drinking level. Male and female participants who reduced their drinking showed increased proportional reinforcement from substance-free activities. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A brief, web-based personalized feedback selective intervention for college student marijuana use: A randomized clinical trial.

Despite clear need, brief web-based interventions for marijuana-using college students have not been evaluated in the literature. The current study was designed to evaluate a brief, web-based personalized feedback intervention for at-risk marijuana users transitioning to college. All entering first-year students were invited to complete a brief questionnaire. Participants meeting criteria completed a baseline assessment (N = 341) and were randomly assigned to web-based personalized feedback or assessment-only control conditions. Participants completed 3-month (95.0%) and 6-month (94.4%) follow-up assessments. Results indicated that although there was no overall intervention effect, moderator analyses found promising effects for those with a family history of drug problems and, to a smaller extent, students who were higher in contemplation of changing marijuana use at baseline. Implications of these findings for selective intervention of college marijuana use and web-based interventions in general are discussed.

A Growth Curve Analysis of the Course of Dysthymic Disorder: The Effects of Chronic Stress and Moderation by Adverse Parent-Child Relationships and Family History.

Using mixed effects models, the authors examined the effects of chronic stress, adverse parent-child relationships, and family history on the 7.5-year course of dysthymic disorder. Participants included 97 outpatients with early-onset dysthymia who were assessed with semistructured interviews at baseline and 3 additional times at 30-month intervals for 7.5 years. Results indicated that higher levels of chronic stress 6 months prior to each follow-up predicted greater depression severity at follow-up, controlling for depression severity at the start of the chronic stress assessment. In addition, adverse parent-child relationships and family history of dysthymic disorder moderated this association. For patients with poorer parent-child relationships, chronic stress was associated with increased depression severity at follow-up, whereas patients with a higher familial loading for dysthymic disorder were less responsive to chronic stress over time.

Relapse prevention training and problem-solving therapy in the long-term management of obesity.

This study compared 2 extended therapy programs for weight management with standard behavioral treatment (BT) without additional therapy contacts. Participants were 80 obese women who completed 20 weekly group sessions of BT and achieved a mean initial weight loss of 8.74 kg. Participants were randomly assigned to a no-further-contact condition (BT only) or to one of two extended interventions consisting of relapse prevention training (RPT) or problem-solving therapy (PST). No significant overall weight-change differences were observed between RPT and BT or between RPT and PST. However, participants who completed the PST intervention had significantly greater long-term weight reductions than BT participants, and a significantly larger percentage of PST participants achieved clinically significant losses of 10% or more in body weight than did BT participants (35% vs 6%).

Practice Makes Progress? Homework Assignments and Outcome in Treatment of Cocaine Dependence.

The relationship between treatment outcome and the extent to which participants completed homework assignments was evaluated among 60 cocaine-dependent individuals assigned to cognitive-behavioral therapy (CBT). Homework was assigned in 72% of all sessions and initiated by participants in 48% of the sessions in which it was assigned. Completion of homework was unrelated to participants' baseline characteristics and several indicators of treatment compliance. Participants who completed more homework assignments demonstrated significantly greater increases in the quantity and quality of their coping skills and used significantly less cocaine during treatment and through a 1-year follow-up. These data suggest that the extent to which participants are willing to complete extrasession assignments may be an important mediator of response to CBT.

Behavior therapy and the transdermal nicotine patch: Effects on cessation outcome, affect, and coping.

The process and outcome of a smoking cessation program using behavior therapy alone (BT) or behavior therapy plus the nicotine patch (BTP) was studied in 64 participants. Participants quit smoking on a target date after a period of ad libitum smoking, cognitive-behavior therapy preparing them for cessation, and behavioral rehearsal for high-risk situations, including stress management, and coping with negative affect. Abstinence was significantly higher for the BTP group versus the BT group from the end of behavioral treatment (79% vs. 63%) through the 3-month follow-up (pp?=?.06) and 12-month marks (p?=?38% vs. 22%). More general distress was observed among BT versus BTP participants ( i.e., increased withdrawal, tension, fatigue, and coping frequency with decreased coping effort; coping-to-urge ratio). The coping behavior of the BTP group may have been more effective than that of the BT group, as indicated by their significantly higher level of self-efficacy.

Improving condom use intentions and behavior by changing perceived partner norms: An evaluation of condom promotion videos for college students.

Objective: To examine the effectiveness of 2 condom promotion videotapes on self-efficacy, intentions, and behavior. Design: Two hundred twenty college students completed social-cognitive and behavioral measures and were then randomly assigned to receive one of two 30-min condom promotion videotapes (male or female student presenters) or to a wait-list control condition. Participants who watched 1 of the videotapes completed immediate posttest measures, and 85% of participants completed a 4-month follow-up. Main Outcome Measures: Self-efficacy for condom use, intentions to use condoms, use of condom during last sex, and consistent condom use over the last month. Results: Participants who received either video reported greater self-efficacy to refuse to have unprotected sex and intentions than controls at follow-up. Individuals who received either video were more likely than controls to report using a condom during last sex with a regular partner, and those who watched the female presenter were more likely to report consistent condom use. Conclusion: Participants benefited in terms of self-efficacy and intentions from receiving either video, but both men and women benefited more in terms of condom use behavior from receiving the female video. Future research is needed to determine whether opposite-sex speaker videos could be beneficial with a larger (and more sexually active) sample and whether these effects are maintained over time.

A randomized controlled trial of online versus clinic-based CBT for adolescent anxiety.

Objective: The study examined the relative efficacy of online (NET) versus clinic (CLIN) delivery of cognitive behavior therapy (CBT) in the treatment of anxiety disorders in adolescents. Method: Participants included 115 clinically anxious adolescents aged 12 to 18 years and their parent(s). Adolescents were randomly assigned to NET, CLIN, or wait list control (WLC) conditions. The treatment groups received equivalent CBT content. Clinical diagnostic interviews and questionnaire assessments were completed 12 weeks after baseline and at 6- and 12-month follow-ups. Results: Assessment at 12 weeks post-baseline showed significantly greater reductions in anxiety diagnoses and anxiety symptoms for both NET and CLIN conditions compared with the WLC. These improvements were maintained or further enhanced for both conditions, with minimal differences between them, at 6- and 12-month follow-ups. Seventy-eight percent of adolescents in the NET group (completer sample) no longer met criteria for the principal anxiety diagnosis at 12-month follow-up compared with 80.6% in the CLIN group. Ratings of treatment credibility from both parents and adolescents were high for NET and equivalent to CLIN. Satisfaction ratings by adolescents were equivalent for NET and CLIN conditions, whereas parents indicated slightly higher satisfaction ratings for the CLIN format. Conclusions: Online delivery of CBT, with minimal therapist support, is equally efficacious as clinic-based, face-to-face therapy in the treatment of anxiety disorders among adolescents. This approach offers a credible alternative to clinic-based therapy, with benefits of reduced therapist time and greater accessibility for families who have difficulty accessing clinic-based CBT.

Randomized controlled trial of motivational enhancement therapy with nontreatment-seeking adolescent cannabis users: A further test of the teen marijuana check-up.

Cannabis use adversely affects adolescents and interventions that are attractive to adolescents are needed. This trial compared the effects of a brief motivational intervention for cannabis use with a brief educational feedback control and a no-assessment control. Participants were randomized into one of three treatment conditions: Motivational Enhancement Therapy (MET), Educational Feedback Control (EFC), or Delayed Feedback Control (DFC). Those who were assigned to MET and EFC were administered a computerized baseline assessment immediately following randomization and completed assessments at the 3- and 12-month follow-up periods. Participants in the DFC condition were not assessed until the 3-month follow-up. Following the completion of treatment sessions, all participants were offered up to four optional individual treatment sessions aimed at cessation of cannabis use. The research was conducted in high schools in Seattle, Washington. The participant s included 310 self-referred adolescents who smoked cannabis regularly. The main outcome measures included days of cannabis use, associated negative consequences, and engagement in additional treatment. At the 3-month follow-up, participants in both the MET and EFC conditions reported significantly fewer days of cannabis use and negative consequences compared to those in the DFC. The frequency of cannabis use was less in MET relative to EFC at 3 months, but it did not translate to differences in negative consequences. Reductions in use and problems were sustained at 12 months, but there were no differences between MET and EFC interventions. Engagement in additional treatment was minimal and did not differ by condition. Brief interventions can attract adolescent cannabis users and have positive impacts on them, but the mechanisms of the effects are yet to be identified.

Targeting Misperceptions of Descriptive Drinking Norms: Efficacy of a Computer-Delivered Personalized Normative Feedback Intervention.

The authors evaluated the efficacy of a computer-delivered personalized normative feedback intervention in reducing alcohol consumption among heavy-drinking college students. Participants included 252 students who were randomly assigned to an intervention or control group following a baseline assessment. Immediately after completing measures of reasons for drinking, perceived norms, and drinking behavior, participants in the intervention condition were provided with computerized information detailing their own drinking behavior, their perceptions of typical student drinking, and actual typical student drinking. Results indicated that normative feedback was effective in changing perceived norms and alcohol consumption at 3- and 6-month follow-up assessments. In addition, the intervention was somewhat more effective at 3-month follow-up among participants who drank more for social reasons. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychological responses to BRCA1 mutation testing: Preliminary findings.

The short-term psychological responses of 60 adult women tested for a BRCA1 gene mutation associated with a high risk of breast and ovarian cancer were investigated. Participants were members of a large kindred enrolled in an ongoing prospective study of the psychosocial impact of genetic testing. Initial results from participants who completed both the pretest baseline and the 1-2 week posttest follow-up interviews are reported. Gene mutation carriers manifested significantly higher levels of test-related psychological distress, as measured by the Impact of Event Scale, when compared with noncarriers. The highest levels of test-related distress were observed among mutation carriers with no history of cancer or cancer-related surgery. Although general distress (state anxiety) declined after testing, carriers were more distressed than noncarriers at follow-up. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Two-Year Prospective Naturalistic Study of Remission From Major Depressive Disorder as a Function of Personality Disorder Comorbidity.

In this study, the authors examined prospectively the 24-month natural course of remission from major depressive disorder (MDD) as a function of personality disorder (PD) comorbidity. In 302 participants (196 women, 106 men), psychiatric and PDs were assessed at baseline with diagnostic interviews, and the course of MDD was assessed with the Longitudinal Interval Follow-Up Evaluation at 6-, 12-, and 24-month follow-ups. Survival analyses revealed an overall 24-month remission rate of 73.5% for MDD that differed little by gender. Participants with MDD who had certain forms of coexisting PD psychopathology (schizotypal, borderline, or avoidant) as their primary PD diagnoses had a significantly longer time to remission from MDD than did patients with MDD without any PD. These PDs emerged as robust predictors of slowed remission from MDD even when controlling for other negative prognostic predictors. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Applying a cognitive behavioral model of health anxiety in a cancer genetics service.

A cognitive-behavioral model of health anxiety was used to investigate reactions to genetic counseling for cancer. Participants (N = 218) were asked to complete a questionnaire beforehand and 6 months later. There was an overall decrease in levels of cancer-related anxiety, although 24% of participants showed increased cancer-related anxiety at follow-up. People who had a general tendency to worry about their health reported more cancer-related anxiety than those who did not at both time points. This health-anxious group also showed a postcounseling anxiety reduction, whereas the others showed no significant change. Participants with breast or ovarian cancer in their family were more anxious than participants with colon cancer in their family. Preexisting beliefs were significant predictors of anxiety, consistent with a cognitive-behavioral approach. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Longitudinal risk factors for intimate partner violence among men in treatment for alcohol use disorders.

Objective: This study examined static and time-varying risk factors for perpetration of intimate partner violence (IPV) among men in treatment for alcohol use disorders. Method: Participants were 178 men diagnosed with alcohol abuse or dependence and their partners. Most (85%) of the men were European American; their average age was 41.0 years. Participants completed measures assessing initial alcohol problem severity, baseline beliefs related to alcohol use, antisocial personality characteristics, alcohol and drug use, relationship adjustment, and IPV. Results: According to couples' reconciled reports, 42% of participants perpetrated IPV at baseline. Among this group, the IPV recurrence rate was 43% at 6-month follow-up and 36% at 12-month follow-up. For participants without IPV perpetration at baseline, new incidence of IPV was 15% and 7% at the 6-month and 12-month follow-up points, respectively. Fixed marker predictors of IPV rates included baseline alcohol problem severity variables, baseline beliefs related to alcohol use, and antisocial personality characteristics. Variable risk factor predictors included alcohol and drug use variables, relationship adjustment factors, and anger. Alcohol use variables and anger were associated with new incidents of IPV among those without reported IPV at baseline only. Conclusions: Findings suggest that assessing and monitoring IPV occurrence by both partners is important for men in treatment for alcohol use disorders. Results indicate vulnerability factors that may identify individuals at risk for IPV and provide targets for IPV prevention among those with alcohol use disorders. These findings can aid in the development of more comprehensive models that more precisely predict IPV. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

What you don't know can hurt you: adverse psychologic effects in members of BRCA1-linked and BRCA2-linked families who decline genetic testing

PURPOSE: To identify members of hereditary breast and ovarian cancer families who are at risk for adverse psychologic effects of genetic testing. PATIENTS AND METHODS: A prospective cohort study with baseline (preeducation) assessments of predictor variables (ie, sociodemographic factors, cancer history, and cancer-related stress symptoms) was performed. The primary outcome variable (presence of depressive symptoms) was assessed at baseline and at 1- and 6-month follow-up evaluations. Participants were 327 adult male and female members of BRCA1- and BRCA2-linked hereditary breast and ovarian cancer families, who were identified as carriers, noncarriers, or decliners of genetic testing. RESULTS: The presence of cancer-related stress symptoms at baseline was strongly predictive of the onset of depressive symptoms in family members who were invited but declined testing. Among persons who reported high baseline levels of stress, depression rates in decliners increased from 26% at baseline to 47% at 1-month follow-up; depression rates in noncarriers decreased and in carriers showed no change (odds ratio [OR] for decliners v noncarriers=8.0; 95% confidence interval [CI], 1.9 to 33.5; P=.0004). These significant differences in depression rates were still evident at the 6-month follow-up evaluation (P=.04). CONCLUSION: In BRCA1/2-linked families, persons with high levels of cancer-related stress who decline genetic testing may be at risk for depression. These family members may benefit from education and counseling, even if they ultimately elect not to be tested, and should be monitored for potential adverse effects.     

Cognitive-behavioral therapy for women with lifelong vaginismus: A randomized waiting-list controlled trial of efficacy.

Women with lifelong vaginismus (N = 117) were randomly assigned to cognitive-behavioral group therapy, cognitive-behavioral bibliotherapy, or a waiting list. Manualized treatment comprised sexual education, relaxation exercises, gradual exposure, cognitive therapy, and sensate focus therapy. Group therapy consisted of ten 2-hr sessions with 6 to 9 participants per group. Assistance with minimal-contact bibliotherapy consisted of 6 biweekly, 15-min telephone contacts. Twenty-one percent of the participants left the study before posttreatment assessment. Intent-to-treat analysis revealed that successful intercourse at posttreatment was reported by 14% of the treated participants compared with none of the participants in the control condition. At the 12-month follow-up 21% of the group therapy participants and 15% of the bibliotherapy participants, respectively, reported successful intercourse. Cognitive-behavioral treatment of lifelong vaginismus was thus found to be efficacious, but the small effect size of the treatment warrants future efforts to improve the treatment.

Effects of question format and collection mode on the accuracy of retrospective surveys of health risk behavior: A comparison with daily sexual activity diaries.

Objective: To use prospective diaries to assess the effects of alternative survey question formats and data collection modes on the accuracy of retrospective self-reports of sexual behavior for the same time period. Design: Over a 3-month period, 493 adults completed and returned by mail daily diaries of their sexual activities. Participants then returned to complete a retrospective survey of their sexual activities during the same 3-month time period. Participants were randomized to 1 of 6 retrospective experimental survey conditions that represented the combinations of 2 question formats (in aggregate and by partner) and 3 collection modes (paper questionnaire, computer-assisted self-interview [CASI], and audio-enhanced CASI). Main Outcome Measures: Frequencies of sexual activities and condom use reported in surveys were compared with what participants had recorded in their prospective daily diaries. Results: Relative to activity recorded in daily diaries, participants more often underreported than overreported (61% vs. 28%, p     

The evaluation of a sexual assault risk reduction program: A multisite investigation.

This article summarizes the results of the Ohio University Sexual Assault Risk Reduction Project, which is a program designed to reduce college women's risk for sexual assault. The program was evaluated at 2 separate universities with 762 women. Participants were randomly assigned either to the program or to the no-treatment comparison group, and they completed measures that assessed sexual victimization, dating behaviors, sexual communication, and rape empathy at the pretest and at the 2-month and 6-month follow-ups. At the 2-month follow-up, there were no differences between the groups on any of the outcome measures. However, those women who were moderately victimized during the 2-month follow-up were significantly less likely to be revictimized during the 6-month follow-up period if they participated in the program.

Benefits of recruiting participants with friends and increasing social support for weight loss and maintenance.

To determine the benefits of social support for weight loss and maintenance, this study recruited participants (N?=?166) either alone or with 3 friends or family members and then randomly assigned then to a standard behavioral treatment (SBT) or SBT with social support strategies. Participants recruited with friends had greater weight losses at the end of the 4-month treatment and at Month 10 follow-up. Both recruitment strategy and the social support manipulation affected treatment completion and weight-loss maintenance. In those recruited alone and given SBT, 76% completed treatment and 24% maintained their weight loss in full from Months 4 to 10. Among those recruited with friends and given SBT plus social support, 95% completed treatment and 66% maintained their weight loss in full. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
