Sudden gains among women receiving treatment for alcohol use disorders

Mechanisms and moderators of behavioural couples therapy for alcohol and substance use disorders: an updated review of the literature

INTRODUCTION

Behavioural couples therapy (BCT) and alcohol behavioural couples therapy (ABCT) are couples-based interventions for substance use disorders (SUDs) that have been deemed a 'gold standard' treatment. Despite the substantial amount of promising research, there is a lack of research on the active components of treatment and treatment mechanisms and moderators. Since the most recent meta-analysis, a number of studies have been conducted that advance our understanding of the efficacy of BCT and ABCT.

AIMS

The purpose of the present review was to provide an update on the current knowledge of these treatments and to investigate mediators and moderators of treatment.

METHOD

A systematic search strategy of relevant databases from 2008 to 2021 identified 20 relevant articles that were coded for relevant information including study design, treatment, outcomes, as well as mechanisms and moderators.

RESULTS

The results indicated that BCT and ABCT are successful in reducing alcohol and substance use for both male and female clients, dual problem couples, and for reducing post-traumatic stress symptoms and intimate partner violence. The reviewed studies discussed a number of treatment mechanisms, with the most studied mechanism being relationship functioning. Moderators included relationship functioning and patient gender.

CONCLUSIONS

The results point to the need for additional research on active treatment components, mechanisms and moderators, in order to provide a more efficient and cost-effective treatment.

Exploring the occurrence of sudden gains among anxious youth receiving evidence-based cognitive-behavioral therapy

BACKGROUND

There is limited information on the occurrence of 'sudden gains' - recognized improvements of substantial magnitude occurring between individual sessions of treatment. This study explores changes in anxiety across sessions of CBT for youth anxiety disorders to determine whether evidence exists for sudden gains in this population.

METHOD

A total of 133 anxious youth (M_age  = 10.16 years; 55.6% male) were randomly assigned to receive 16 sessions of individual cognitive-behavioral therapy (ICBT), family-based CBT (FCBT), or a family-based educational support and attention control (FESA). At each treatment session, youth completed a measure of anxiety. Sudden gains were calculated from weekly state anxiety scores using methods consistent with previous research (i.e., Tang & DeRubeis, 1999).

RESULTS

Three participants experienced a sudden gain at any point during treatment; all experienced a reversal of the sudden gain, although one experienced a regain of the improvement that occurred during the sudden gain.

CONCLUSIONS

While sudden gains have been demonstrated in some studies, in a relatively new topic to the literature such as this, it should also be considered that many evidence-based treatments are actually intended to produce more steady/gradual gains - which may be particularly true for youth who are not as cognitively advanced as adults and who have much to learn about how psychopathology - and for this analysis, anxiety - operates.

Moderators of sudden gains after sessions addressing emotion regulation among women in treatment for alcohol use

Sudden gains (SGs) are defined as abrupt and significant improvements in mental health symptoms that occur between two psychotherapy sessions. Preliminary evidence suggests that SGs may be an important pattern of symptom reduction in the treatment of alcohol use disorder (AUD) (i.e., a steep between-session reduction in drinking or alcohol craving frequency or intensity) (Drapkin, Epstein, McCrady, & Eddie, 2015). The current study examined SGs within two randomized clinical trials (RCTs) testing female-specific cognitive behavior therapy (CBT) protocol for AUD (n=146). We tested a priori hypotheses about whether women's baseline depression, anxiety, and confidence to be abstinent while in a negative emotional state would predict attainment of SGs after attending sessions that addressed depression, anxiety, and emotion regulation (i.e., sessions five and six of the 12-session protocol). Data were collected at baseline, within treatment, and 15months after baseline. Results showed that women with high levels of depression and/or anxiety and low confidence to be abstinent in a negative emotional state at baseline were more likely to experience a SG (steep decrease in drinking) after sessions five and six (p=0.02). Further, among women with high levels of depression and/or anxiety at baseline, those who experienced both a SG in drinking after session five/six and had higher confidence to remain abstinent in a negative emotional state at the end of treatment reported lower drinking frequency at 9- but not 15-month follow-up [95% CI=(-2.65, -0.86)]. Findings support the value of providing interventions targeting mood and emotion regulation in AUD treatment for women.
