Efficacy of a randomized controlled trial of integrative couple treatment for pathological gambling (ICT-PG): 10-month follow-up.

OBJECTIVE: Assess the efficacy of integrative couple treatment for pathological gambling (ICT-PG) in comparison to treatment provided in an individual approach. METHOD: Eighty couples were assigned randomly to ICT-PG (n = 44, Mage = 42.2, SD [13.4], n male gamblers = 29) or individual treatment (n = 36, Mage = 39.9 SD [13.0], n male gamblers = 31) with follow-ups at 4- and 10-months postadmission regarding the severity of gambling, the individual and couple's well-being. Linear mixed and generalized estimating equation models for repeated measures were applied to take into account the dependency of observations. Protocol was preregistered at www. CLINICALTRIALS: gov (ID: NCT02240485). RESULTS: Participants in both treatments generally improved over time with reductions on gambling expanses from an initial $4,000-$600 in a 90-day period following treatment, without difference across treatment conditions in money spent on gambling or frequency of gambling. However, on different indices of gambling severity, the participants in ICT-PG showed more improvement at follow-ups, with better control capacity (OR = 2.57, p < .0129) and greater reduction in gambling craving (OR = 5.83, p < .0001) and erroneous cognitions (OR = 2.63, p < .0063). The couple treatment was associated with a better individual well-being (e.g., less depression for partners, OR = 5.53; p < .0351, and gamblers, OR = 2.37; p < .0334) and couple well-being (e.g., better dyadic satisfaction for partners, OR = 2.02; p < .0057, and gamblers, OR = 3.07; p < .0212). CONCLUSIONS: The results underline the necessity to provide a greater diversity of treatment for gamblers and their partner. Further research should focus on identifying active components of ICT-PG and widen its provision to gamblers with concurrent addiction disorders.

A systematic review and meta-analysis of the efficacy of the long-term treatment and support of substance use disorders.

RATIONALE: The reconceptualization of substance use disorders (SUD) as a chronic phenomenon calls for a paradigm shift in service provision, particularly by way of long-term treatment and support. Studies that have evaluated the efficacy of long-term treatment models seem to indicate that they are an improvement on more standard short-term treatments, even though these studies do not take the durations into consideration. OBJECTIVE: Measure the efficacy of SUD treatments and support lasting 18 months or more regarding their ability to decrease substance use as compared to shorter treatments. METHODS: A meta-analysis based on a systematic literature review was conducted. Eight databases were consulted for peer-reviewed studies. Certain variables were coded as moderators: intervention length, participant characteristics, and treatment characteristics. RESULTS: The main results suggest that the people who received a planned long-term treatment or support had a 23.9 % greater chance of abstaining or consuming moderately than did people who received a shorter standard treatment (OR = 1.347 [CI 95 % = 1.087-1.668], p < .006, adjusted OR = 1.460 [CI 95 % = 1.145-1.861]). None of the moderation analyses revealed any variation in the efficacy of the long-term treatments and support. CONCLUSIONS: The reconceptualization of the SUD as a chronic disorder among people with this problem leads us to reconsider both the length of the services provided and the paradigms underlying their organization.
