The cost-effectiveness of family/family-based therapy for treatment of externalizing disorders, substance use disorders and delinquency: a systematic review.

BACKGROUND: Family therapy and family-based treatment has been commonly applied in children and adolescents in mental health care and has been proven to be effective. There is an increased interest in economic evaluations of these, often expensive, interventions. The aim of this systematic review is to summarize and evaluate the evidence on cost-effectiveness of family/family-based therapy for externalizing disorders, substance use disorders and delinquency. METHODS: A systematic literature search was performed in PubMed, Education Resource information Centre (ERIC), Psycinfo and Cochrane reviews including studies conducted after 1990 and before the first of August of 2013. Full economic evaluations investigating family/family-based interventions for adolescents between 10 and 20 years treated for substance use disorders, delinquency or externalizing disorders were included. RESULTS: Seven hundred thirty-one articles met the search criteria and 51 studies were initially selected. The final selection resulted in the inclusion of 11 studies. The quality of these studies was assessed. Within the identified studies, there was great variation in the specific type of family/family-based interventions and disorders. According to the outcomes of the checklists, the overall quality of the economic evaluations was low. Results varied by study. Due to the variations in setting, design and outcome it was not feasible to pool results using a meta-analysis. CONCLUSIONS: The quality of the identified economic evaluations of family/family-based therapy for treatment of externalizing disorders, adolescent substance use disorders and delinquency was insufficient to determine the cost-effectiveness. Although commonly applied, family/family-based therapy is costly and more research of higher quality is needed.

Motivational and control mechanisms underlying adolescent cannabis use disorders: A prospective study.

Cannabis use disorders (CUDs) are the most prevalent substance use disorders among adolescents in treatment. Yet, little is known about the neuropsychological mechanisms underlying adolescent CUDs. Studies in adult cannabis users suggest a significant role for cognitive control and cannabis-oriented motivational processes, such as attentional bias, approach bias, and craving in CUDs. The current 6-month prospective study investigated the relationships between attentional bias, approach bias, craving, cognitive control, and cannabis use in adolescent patients in treatment for a primary or secondary CUD. Moreover, we investigated if these motivational processes and cognitive control could predict treatment progression after 6 months. Adolescents with a CUD had an attentional but no approach bias towards cannabis. In contrast to adult findings on the role of attentional bias, approach bias and cognitive control, only cannabis craving significantly correlated with current cannabis use and predicted cannabis use-related problems and abstinence from cannabis 6 months later. These findings identify craving as a predictor of treatment outcome, thereby supporting an important role for craving in the course of adolescent cannabis use and dependence. This prospective study is among the first to investigate neuropsychological mechanisms underlying adolescent CUDs, warranting future longitudinal studies.

Matching adolescents with a cannabis use disorder to multidimensional family therapy or cognitive behavioral therapy: treatment effect moderators in a randomized controlled trial.

BACKGROUND: In a recent randomized controlled trial (Hendriks et al., 2011), multidimensional family therapy (MDFT) and cognitive behavioral therapy (CBT) were equally effective in reducing cannabis use in adolescents (13-18 years old) with a cannabis use disorder (n=109). In a secondary analysis of the trial data, we investigated which pretreatment patient characteristics differentially predicted treatment effect in MDFT and CBT, in order to generate hypotheses for future patient-treatment matching. METHODS: The predictive value of twenty patient characteristics, in the area of demographic background, substance use, substance-related problems, delinquency, treatment history, psychopathology, family functioning and school or work related problems, was investigated in bivariate and subsequent multivariate linear regression analyses, with baseline to month 12 reductions in cannabis use days and smoked joints as dependent variables. RESULTS: Older adolescents (17-18 years old) benefited considerably more from CBT, and younger adolescents considerably more from MDFT (p<0.01). Similarly, adolescents with a past year conduct or oppositional defiant disorder, and those with internalizing problems achieved considerably better results in MDFT, while those without these coexisting psychiatric problems benefited much more from CBT (p<0.01, and p=0.02, respectively). CONCLUSIONS: The current study strongly suggests that age, disruptive behavior disorders and internalizing problems are important treatment effect moderators of MDFT and CBT in adolescents with a cannabis use disorder. If replicated, this finding suggests directions for future patient-treatment matching in adolescent substance abuse treatment.

The influence of a local, media covered hospital incident on public trust in health care.

BACKGROUND: Incidents in health care happen every now and then. Incidents are often extensively covered by the news media. In this study, we investigated the impact of an incident in a Dutch hospital on public trust in health care in the population living in the vicinity of where the incident took place and in the national population. News media coverage of the incident started in Fall 2008. METHODS: We collected data in three samples, using a postal questionnaire on public trust in health care. Two samples were a cross-section of the Dutch population; one was questioned in October 2006 and the other in October 2008. The third sample, also questioned in October 2008, consisted of 1000 people living in the surrounding area of the hospital where the incident occurred. The cross-sectional sample of October 2006 was a reference group, and at that time no incidents in health care were covered in the media. RESULTS: In the local population, the incident had a strong impact on public trust in the hospital and among the specialists working there. Also, in the local population, the impact of the incident was generalized to trust in hospitals and specialists in general. In the national population, no impact of the incident on the public's trust was found, despite national news media coverage. CONCLUSION: Local incidents have an impact on public trust in health care in the local population. However, these incidents do not influence public trust in health care in the national population.

Treatment of adolescents with a cannabis use disorder: main findings of a randomized controlled trial comparing multidimensional family therapy and cognitive behavioral therapy in The Netherlands.

BACKGROUND: To meet the treatment needs of the growing number of adolescents who seek help for cannabis use problems, new or supplementary types of treatment are needed. We investigated whether multidimensional family therapy (MDFT) was more effective than cognitive behavioral therapy (CBT) in treatment-seeking adolescents with a DSM-IV cannabis use disorder in The Netherlands. METHODS: One hundred and nine adolescents participated in a randomized controlled trial, with study assessments at baseline and at 3, 6, 9 and 12 months following baseline. They were randomly assigned to receive either outpatient MDFT or CBT, both with a planned treatment duration of 5-6 months. Main outcome measures were cannabis use, delinquent behavior, treatment response and recovery at one-year follow-up, and treatment intensity and retention. RESULTS: MDFT was not found to be superior to CBT on any of the outcome measures. Adolescents in both treatments did show significant and clinically meaningful reductions in cannabis use and delinquency from baseline to one-year follow-up, with treatment effects in the moderate range. A substantial percentage of adolescents in both groups met the criteria for treatment response at month 12. Treatment intensity and retention was significantly higher in MDFT than in CBT. Post hoc subgroup analyses suggested that high problem severity subgroups at baseline may benefit more from MDFT than from CBT. CONCLUSIONS: The current study indicates that MDFT and CBT are equally effective in reducing cannabis use and delinquent behavior in adolescents with a cannabis use disorder in The Netherlands.

Determinants of public trust in complementary and alternative medicine.

BACKGROUND: In the Netherlands, public trust in conventional medicine is relatively high. There is reason to believe that public trust in complementary and alternative medicine (CAM) is rated lower. The aim of this study is to gain insight into public trust in CAM and the determinants that lie at the root of it. We hypothesized that public trust in CAM is related to (perceived) institutional guarantees, media information on CAM, information from people's social network, personal experiences, the role of general practitioners (GPs) and trust in conventional medicine. METHODS: A postal questionnaire on public trust in CAM was mailed to 1358 members of the Health Care Consumer Panel. 65% of the questionnaires were returned. Data were analysed using frequencies, ANOVA, post hoc testing and linear regression analyses. RESULTS: In the total sample, the level of public trust in CAM was a 5.05 on average on a scale of 1-10. 40.7% was CAM user (current or past) and displayed significantly higher levels of trust toward CAM than CAM non users. In the total sample, public trust in CAM was related to institutional guarantees, negative media information, positive and negative information reported by their social network and people's personal experiences with CAM. For non users, trust is mostly associated with institutional guarantees. For users, personal experiences are most important. For both users and non users, trust levels in CAM are affected by negative media information. Public trust in CAM is for CAM users related to positive information and for non users to negative information from their network. CONCLUSIONS: In the Netherlands, CAM is trusted less than conventional medicine. The hypotheses on institutional guarantees, media information, information from the network and people's personal experiences are confirmed by our study for the total sample, CAM non users and users. The other hypotheses are rejected.

Public trust in health care: a comparison of Germany, The Netherlands, and England and Wales.

This article describes public trust in health care in three European countries. Public trust is a generalised attitude, influenced by people's experiences in contacts with representatives of institutions, in its turn influencing how people enter these contacts. In general, people in Germany have less trust in health care, while people in England and Wales have the highest trust levels. Cultural differences between the three countries could be an important source of differences. That makes public trust a less straightforward candidate for use as indicator of the future oriented dimension of user views in an international, comparative performance framework.

Public trust in health care: a performance indicator?

PURPOSE: If public trust in health care is to be used as a performance indicator for health care systems, its measurement has to be sensitive to changes in the health care system. For this purpose, this study has monitored public trust in health care in The Netherlands over an eight-year period, from 1997 to 2004. The study expected to find a decrease in public trust, with a low point in 2002. DESIGN/METHODOLOGY/APPROACH: Since 1997, public trust in health care was measured through postal questionnaires to the "health care consumer panel". This panel consists of approximately 1500 households and forms a representative sample of the Dutch population. FINDINGS: Trust in health care and trust in hospitals did not show any significant trend. Trust in medical specialists displayed an upward trend. Trust in future health care, trust in five out of six dimensions of health care and trust in general practitioners actually did show a decrease. However, only for trust in macro level policies and trust in professional expertise this trend continued. For the remaining trust objects, after 1999 or 2000, an upward trend set in. RESEARCH IMPLICATIONS/LIMITATIONS: No support was found for our overall assumption. Explanations for the fact that trust did increase after 1999 or 2000 are difficult to find. On the basis of these findings the study questions whether the measure of public trust is sensitive enough to provide information on the performance of the health care system. ORIGINALITY/VALUE: The aim of this research is to study public trust in health care on its abilities to be used as a performance indicator for health care systems.
