RESUMEN
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.

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.

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.

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.
