Comparing the acceptability of a positive psychology intervention versus a cognitive behavioural therapy for clinical depression

There is growing evidence on the efficacy of positive psychology interventions (PPI) to treat clinical disorders. However, very few studies have addressed their acceptability. The present study aimed to analyse 2 key components of acceptability (i.e., client satisfaction and adherence to treatment) of a new PPI programme, the Integrative Positive Psychological Intervention for Depression (IPPI‐D), in comparison to a standard cognitive behavioural therapy (CBT) programme in the treatment of clinical depression. One hundred twenty‐eight women with a DSM‐IV diagnosis of major depression or dysthymia were allocated to a 10‐session IPPI‐D or CBT group intervention condition. Results showed that both interventions were highly acceptable for participants. Attendance rates were high, and there were no significant differences between conditions. However, the IPPI‐D condition showed significantly higher client satisfaction than the CBT condition. Moreover, acceptability did not differ based on participants' severity of symptoms, regardless of condition. These findings encourage further investigations of the applicability of PPI in clinical settings in order to broaden the range of acceptable and suitable therapies for depressed patients. Key Practitioner Message

• This study sheds light on the client satisfaction and adherence to a positive intervention.
• For participants, positive psychology interventions (PPI) may be more satisfactory than CBT as PPI are framed within a positive mental health model and, consequently, may reduce the risk of stigmatization
• Because acceptability of treatments and preferences may affect the efficacy of treatments, this study provides an excellent opportunity to offer professionals more therapeutic options to tailor treatments to clients' needs and expectations

     

Web-based cognitive behavior therapy for depression with and without telephone tracking in a national helpline: secondary outcomes from a randomized controlled trial

Background

An earlier report indicated that callers to a telephone counseling service benefited from the addition of an evidence-based Web intervention for depression. It is not known whether the Web intervention would also lower alcohol use and stigma, or improve quality of life and knowledge of depression and its treatments.

Objective

To report the secondary outcomes of a trial of a Web-based cognitive behavior therapy (CBT) intervention for depression, including hazardous alcohol use, quality of life, stigma, depression literacy, and CBT literacy.

Methods

We recruited a sample of 155 callers to Lifeline, a national telephone counseling service in Australia, who met the criteria for moderate to high psychological distress. Participants were randomly assigned to 1 of 4 conditions: (1) Web CBT plus weekly telephone tracking, (2) Web CBT only, (3) weekly telephone tracking only, and (4) neither Web CBT nor telephone tracking. Participants were assessed at preintervention, postintervention, and 6 and 12 months postintervention.

Results

At postintervention, participants who completed the Web intervention either with or without telephone support had lower levels of hazardous alcohol use (without tracking: P = .008, effect size = 0.23; with tracking: P = .003, effect size = 0.26), improved quality of life (without tracking: P = .001, effect size = 0.81; with tracking: P = .009, effect size = 0.63), and improved CBT literacy (without tracking: P = .01, effect size = 0.71; with tracking: P < .001, effect size = 0.80) compared with those who did not receive the Web intervention or telephone support. Results for quality of life and CBT literacy were maintained at 6- and 12-month’s follow-up, but differences in hazardous alcohol use were not significantly different between conditions at 6 and 12 months. Although omnibus tests for depression literacy and stigma were nonsignificant, contrasts revealed that those in the Web-only condition showed significantly lower levels of stigma than participants in the control condition at postintervention. This was true for participants in the Web-only and Web plus tracking conditions at 6 months. Similarly, those in the Web-only and Web plus tracking conditions had significantly higher depression literacy at postintervention, and this was maintained in the Web-only condition at 6-months’ follow-up. No significant differences were found in depression literacy and stigma between conditions at 12 months.

Conclusions

Evidence-based Web interventions for depression can be effective not only in reducing depression symptoms but also in improving other health outcomes, including quality of life, hazardous alcohol use, and knowledge about effective strategies for depression self-management.

Exploring patients' reasons for declining contact in a cognitive behavioural therapy randomised controlled trial in primary care

Background

The difficulties of recruiting individuals into mental health trials are well documented. Few studies have collected information from those declining to take part in research, in order to understand the reasons behind this decision.

Aim

To explore patients'' reasons for declining to be contacted about a study of the effectiveness of cognitive behavioural therapy as a treatment for depression.

Design and setting

Questionnaire and telephone interview in general practices in England and Scotland.

Method

Patients completed a short questionnaire about their reasons for not taking part in research. Semi-structured telephone interviews were conducted with a purposive sample to further explore reasons for declining.

Results

Of 4552 patients responding to an initial invitation to participate in research involving a talking therapy, 1642 (36%) declined contact. The most commonly selected reasons for declining were that patients did not want to take part in a research study (n = 951) and/or did not want to have a talking therapy (n = 688) (more than one response was possible). Of the decliners, 451 patients agreed to an interview about why they declined. Telephone interviews were completed with 25 patients. Qualitative analysis of the interview data indicated four main themes regarding reasons for non-participation: previous counselling experiences, negative feelings about the therapeutic encounter, perceived ineligibility, and misunderstandings about the research.

Conclusion

Collecting information about those who decline to take part in research provides information on the acceptability of the treatment being studied. It can also highlight concerns and misconceptions about the intervention and research, which can be addressed by researchers or recruiting GPs. This may improve recruitment to studies and thus ultimately increase the evidence base.     

Internet-based cognitive behavioural therapy programme with and without videoconference guidance sessions: A randomized controlled trial to treat work-related symptoms of anxiety and depression

This study provides the results from the implementation of a highly structured therapist-guided iCBT programme for people with work-related anxiety and depression, in terms of programme efficacy, participants' adherence and satisfaction. Seventy-seven national police workers were randomly allocated to one of two groups: without additional videoconference sessions (web platform with guidance of therapist) and with additional videoconference sessions (same intervention as the previous group, plus two videoconference guidance sessions with a psychologist). The intervention was composed of 12 sessions and took place for 17–20 weeks. We found an adherence rate of 36.4%, with no differences between groups. All participants endorsed lower depression (BDI-II F(1) = 36.98, p < .001; ATQ F(1) = 24.22, p < .001), and anxiety (STAI-State F(1) = 76.62, p < .001) after the programme. As a variable related to anxiety and depression in workplace, participants also showed higher assertiveness levels (RAS F(1) = 8.96, p < .001). A significant reduction of the mean level of anxiety perceived by participants as the intervention programme progressed was observed in both groups (F(2) = 7.44; p = .003). Participants were satisfied with the therapists' intervention and with the programme. No significant group effects were found for any of the measures. Reduction in depression levels was maintained in the 12-month follow-up, but levels of anxiety increased. This study is innovative, as it is the first controlled trial to analyse the effect of two added videoconference sessions, and it includes short- and long-term measures, which is not usual. The results are discussed to clarify the role of the contact with the therapist to improve treatment adherence.     

Delivering cognitive behavioural therapy to advanced cancer patients: A qualitative exploration into therapists' experiences within a UK psychological service

Background

Cognitive behavioural therapy (CBT) is commonly used to treat cancer patients with psychological disorders such as depression. There has been little qualitative research exploring the experience of therapists delivering CBT to patients with advanced cancer and long‐term health conditions generally. Therapists' views may help identify difficulties in delivering therapy and how these may be overcome. The aim of this study was to inform practice by qualitatively exploring the experiences of therapists delivering CBT to patients with advanced cancer.

Design

Sixteen semi‐structured interviews were conducted with therapists from Increasing Access to Psychological Therapy (IAPT) services in London, UK, who had delivered CBT to patients enrolled on the CanTalk trial. Interviews were recorded, transcribed, and analysed using framework analysis.

Results

Therapists reported positive experiences when working with the target population. Flexibility, adaptability, and a consideration of individual needs were identified as important when delivering CBT, but the rigidity of IAPT policies and demand for services were perceived as problematic. Although therapists reported adequate training, specialist supervision was desired when delivering therapy to this complex population.

Conclusion

IAPT therapists can deliver CBT to advanced cancer patients, given therapists positive experiences evident in the present study. However, it was concluded that additional service and modifications of therapy may be needed before positive outcomes for both therapists and patients can be achieved.

     

MEMO--a mobile phone depression prevention intervention for adolescents: development process and postprogram findings on acceptability from a randomized controlled trial

Background

Prevention of the onset of depression in adolescence may prevent social dysfunction, teenage pregnancy, substance abuse, suicide, and mental health conditions in adulthood. New technologies allow delivery of prevention programs scalable to large and disparate populations.

Objective

To develop and test the novel mobile phone delivery of a depression prevention intervention for adolescents. We describe the development of the intervention and the results of participants’ self-reported satisfaction with the intervention.

Methods

The intervention was developed from 15 key messages derived from cognitive behavioral therapy (CBT). The program was fully automated and delivered in 2 mobile phone messages/day for 9 weeks, with a mixture of text, video, and cartoon messages and a mobile website. Delivery modalities were guided by social cognitive theory and marketing principles. The intervention was compared with an attention control program of the same number and types of messages on different topics. A double-blind randomized controlled trial was undertaken in high schools in Auckland, New Zealand, from June 2009 to April 2011.

Results

A total of 1348 students (13–17 years of age) volunteered to participate at group sessions in schools, and 855 were eventually randomly assigned to groups. Of these, 835 (97.7%) self-completed follow-up questionnaires at postprogram interviews on satisfaction, perceived usefulness, and adherence to the intervention. Over three-quarters of participants viewed at least half of the messages and 90.7% (379/418) in the intervention group reported they would refer the program to a friend. Intervention group participants said the intervention helped them to be more positive (279/418, 66.7%) and to get rid of negative thoughts (210/418, 50.2%)—significantly higher than proportions in the control group.

Conclusions

Key messages from CBT can be delivered by mobile phone, and young people report that these are helpful. Change in clinician-rated depression symptom scores from baseline to 12 months, yet to be completed, will provide evidence on the effectiveness of the intervention. If proven effective, this form of delivery may be useful in many countries lacking widespread mental health services but with extensive mobile phone coverage.

Rational emotive behavior therapy, cognitive therapy, and medication in the treatment of major depressive disorder: a randomized clinical trial, posttreatment outcomes, and six-month follow-up

A randomized clinical trial was undertaken to investigate the relative efficacy of rational-emotive behavior therapy (REBT), cognitive therapy (CT), and pharmacotherapy in the treatment of 170 outpatients with nonpsychotic major depressive disorder. The patients were randomly assigned to one of the following: 14 weeks of REBT, 14 weeks of CT, or 14 weeks of pharmacotherapy (fluoxetine). The outcome measures used were the Hamilton Rating Scale for Depression and the Beck Depression Inventory. No differences among treatment conditions at posttest were observed. A larger effect of REBT (significant) and CT (nonsignificant) over pharmacotherapy at 6 months follow-up was noted on the Hamilton Rating Scale for Depression only.     

Insomnia as a mediating therapeutic target for depressive symptoms: A sub‐analysis of participant data from two large randomized controlled trials of a digital sleep intervention

Insomnia predicts the onset of depression, commonly co‐presents with depression and often persists following depression remission. However, these conditions can be challenging to treat concurrently using depression‐specific therapies. Cognitive behavioural therapy for insomnia may be an appropriate treatment to improve both insomnia and depressive symptoms. We examined the effects of a fully‐automated digital cognitive behavioural therapy intervention for insomnia (Sleepio) on insomnia and depressive symptoms, and the mediating role of sleep improvement on depressive symptoms in participants from two randomized controlled trials of digital cognitive behavioural therapy for insomnia. We also explored potential moderators of intervention effects. All participants met criteria for probable insomnia disorder and had clinically significant depressive symptomatology (PHQ‐9 ≥ 10; n = 3,352). Individuals allocated to treatment in both trials were provided access to digital cognitive behavioural therapy. Digital cognitive behavioural therapy significantly improved insomnia (p < .001; g = 0.76) and depressive symptoms (p < .001; g = 0.48) at post‐intervention (weeks 8–10), and increased the odds (OR = 2.9; 95% CI = 2.34, 3.65) of clinically significant improvement in depressive symptoms (PHQ‐9 < 10). Improvements in insomnia symptoms at mid‐intervention mediated 87% of the effects on depressive symptoms at post‐intervention. No variables moderated effectiveness outcomes, suggesting generalizability of these findings. Our results suggest that effects of digital cognitive behavioural therapy for insomnia extend to depressive symptoms in those with clinically significant depressive symptomatology. Insomnia may, therefore, be an important therapeutic target to assist management of depressive symptoms.

Internet-based cognitive behavioural therapy for subthreshold depression in people over 50 years old: a randomized controlled clinical trial

BACKGROUND: Subthreshold depression is a highly prevalent condition and a risk factor for developing a major depressive episode. Internet-based cognitive behaviour therapy may be a promising approach for the treatment of subthreshold depression. The current study had two aims: (1) to determine whether an internet-based cognitive behaviour therapy intervention and a group cognitive behaviour therapy intervention are more effective than a waiting-list control group; and (2) to determine whether the effect of the internet-based cognitive behaviour therapy differs from the group cognitive behaviour therapy intervention. METHOD: A total of 191 women and 110 men with subthreshold depression were randomized into internet-based treatment, group cognitive behaviour therapy (Lewinsohn's Coping With Depression course), or a waiting-list control condition. The main outcome measure was treatment response after 10 weeks, defined as the difference in pre- and post-treatment scores on the Beck Depression Inventory (BDI). Missing data, a major limitation of this study, were imputed using the Multiple Imputation (MI) procedure Data Augmentation. RESULTS: In the waiting-list control group, we found a pre- to post-improvement effect size of 0.45, which was 0.65 in the group cognitive behaviour therapy condition and 1.00 within the internet-based treatment condition. Helmert contrasts showed a significant difference between the waiting-list condition and the two treatment conditions (p=0.04) and no significant difference between both treatment conditions (p=0.62). CONCLUSIONS: An internet-based intervention may be at least as effective as a commonly used group cognitive behaviour therapy intervention for subthreshold depression in people over 50 years of age.     

A randomized,controlled pilot study of cognitive analytic therapy for stressed pregnant women with underlying anxiety and depression in a routine health service setting

A pilot study of cognitive analytic therapy (CAT) plus treatment as usual (TAU), versus TAU in stressed pregnant women with anxiety and depression, was undertaken as an essential preliminary to any definitive, randomized controlled trial (RCT). The trial was pragmatic, multicentre, parallel, randomized, controlled, and unblinded. Participants were pregnant women screened using the Hospital Anxiety and Depression Scale (HADS). Treatment was standard 16-session CAT. Main outcome measures were Spielberger State/Trait Anxiety Inventory (STAI) (primary outcome measure) at 24 weeks after randomization, therefore 1 month after therapy for the CAT group; HADS; Clinical Outcomes in Routine Evaluation—Outcome Measure (CORE-OM); Edinburgh Postnatal Depression Scale (EPDS); 36-item Short Form Health Survey (SF-36); and a brief Experiences of Therapy Questionnaire, completed at baseline and on average at 12, 24, 40, and 82 weeks after randomization. Thirty-nine patients (CAT + TAU, n = 20; TAU, n = 19) were randomized with mean baseline STAI State scores of 50.8 (SD 11.4) and 51.1 (SD 13.3), respectively. Sixteen patients had missing primary outcome data leaving 23 (n = 11 and n = 12) patients for analysis. The mean STAI State score was 38.5 (SD 13.8) and 45.7 (SD 16.8) in the CAT and TAU groups respectively at 24 weeks after randomization, with an adjusted difference in means of 7.2 (95% confidence interval [CI]: −7.9 to 20.6). No safety issues were reported. Patient retention for the CAT group was high (18/20; 90% of patients completed therapy). Ten out of 11 (90.9%) respondents ‘agreed’ or ‘strongly agreed’ that having CAT had been ‘very helpful’. The study demonstrated the feasibility of safely undertaking CAT in this setting. Outcomes showed positive trends compatible with a clinically important effect, although statistically definitive conclusions cannot be drawn in such a study.
