Acceptability of psychotherapy, pharmacotherapy, and self-directed therapies in Australians living with chronic hepatitis C

Pilot CBT trial for anxiety in alcohol use disorders treatment

Purpose

– The purpose of this paper is to test the effectiveness of a self-directed cognitive behavioural therapy (CBT) booklet allowing immediate access to treatment for anxiety during alcohol use disorder (AUD) interventions.

Design/methodology/approach

– Parallel pilot randomised controlled trial: 69 individuals in AUD treatment, continued to receive treatment alone (control: n=29) or in addition, a self-directed, four week CBT booklet to manage anxiety (intervention: n=40). Primary outcome measures were changes in state (SAnx) and trait anxiety (TAnx) at four weeks. Secondary outcome measures were changes in adaptive (ACop), maladaptive (MCop) coping and quality of life (QoL, physical (PHQoL), psychological (PSQoL), social (SQoL), environment (EQoL)) at four weeks.

Findings

– Participants had significantly higher SAnx (p < 0.01) and TAnx (p < 0.01) baseline scores compared to the general population. There were no statistically significant group changes in SAnx or TAnx (p > 0.05). Control group allocation predicted improvement in ACop (p < 0.01), MCop (p < 0.05), PHQoL (p < 0.01), PSQoL (p < 0.05) and SQoL (p < 0.01); CBT group allocation predicted improvement in EQoL (p=0.05). All effect sizes were small to moderate (Cohen’s d < 0.50). Percentage of book completion did not determine changes in anxiety, coping or quality of life.

Originality/value

– A four week self-directed CBT booklet did not significantly reduce anxiety during AUD treatment. Larger sample sizes will determine the most suitable treatment delivery mode for this type of CBT.

An Aggravated Trajectory of Depression and Anxiety Co-morbid with Hepatitis C: A Within-groups Study of 61 Australian Outpatients

Background: This study aimed to explore the course of depression and anxiety in chronic hepatitis C patients. Methods:  Data were combined from two studies: (1) Hospital Anxiety and Depression Scale (HADS) scores in 395 consecutive Australian outpatients from 2006 to 2010 formed the baseline measurement; and (2) Depression Anxiety Stress Scales (DASS) scores in a survey of a sub-sample of these patients in 2011 formed the follow-up measurement. After converting DASS to HADS scores, changes in symptom scores and rates of case-ness (≥8), and predictors of follow-up symptoms were assessed. Results:  Follow-up data were available for 61 patients (70.5% male) whose age ranged from 24.5 to 74.6 years (M=45.6). The time to follow-up ranged from 20.7 to 61.9 months (M=43.8). Baseline rates of depression (32.8%) and anxiety (44.3%) increased to 62.3% and 67.2%, respectively. These findings were confirmed, independent of the conversion, by comparing baseline HADS and follow-up DASS scores with British community norms. Baseline anxiety and younger age predicted depression, while baseline anxiety, high school non-completion, and single relationship status predicted anxiety. Conclusion:  This study demonstrated a worsening trajectory of depression and anxiety. Further controlled and prospective research in a larger sample is required to confirm these findings.
