Effectiveness of a web-based self-help intervention for symptoms of depression, anxiety, and stress: randomized controlled trial

Background

Self-help therapies are often effective in reducing mental health problems. We developed a new Web-based self-help intervention based on problem-solving therapy, which may be used for people with different types of comorbid problems: depression, anxiety, and work-related stress.

Objective

The aim was to study whether a Web-based self-help intervention is effective in reducing depression, anxiety, and work-related stress (burnout).

Methods

A total of 213 participants were recruited through mass media and randomized to the intervention (n = 107) or a waiting list control group (n = 106). The Web-based course took 4 weeks. Every week an automated email was sent to the participants to explain the contents and exercises for the coming week. In addition, participants were supported by trained psychology students who offered feedback by email on the completed exercises. The core element of the intervention is a procedure in which the participants learn to approach solvable problems in a structured way. At pre-test and post-test, we measured the following primary outcomes: depression (CES-D and MDI), anxiety (SCL-A and HADS), and work-related stress (MBI). Quality of life (EQ-5D) was measured as a secondary outcome. Intention-to-treat analyses were performed.

Results

Of the 213 participants, 177 (83.1%) completed the baseline and follow-up questionnaires; missing data were statistically imputed. Of all 107 participants in the intervention group, 9% (n = 10) dropped out before the course started and 55% (n = 59) completed the whole course. Among all participants, the intervention was effective in reducing symptoms of depression (CES-D: Cohen’s d = 0.50, 95% confidence interval (CI) 0.22-0.79; MDI: d = 0.33, 95% CI 0.03-0.63) and anxiety (SCL-A: d = 0.42, 95% CI 0.14-0.70; HADS: d = 0.33, 95% CI 0.04-0.61) as well as in enhancing quality of life (d = 0.31, 95% CI 0.03-0.60). Moreover, a higher percentage of patients in the intervention group experienced a significant improvement in symptoms (CES-D: odds ratio [OR] = 3.5, 95% CI 1.9-6.7; MDI: OR = 3.7, 95% CI 1.4-10.0; SCL-A: OR = 2.1, 95% CI 1.0-4.6; HADS: OR = 3.1, 95% CI 1.6-6.0). Patients in the intervention group also recovered more often (MDI: OR = 2.2; SCL-A: OR = 2.0; HADS < 8), although these results were not statistically significant. The course was less effective for work-related stress, but participants in the intervention group recovered more often from burnout than those in the control group (OR = 4.0, 95% CI 1.2-13.5).

Conclusions

We demonstrated statistically and clinically significant effects on symptoms of depression and anxiety. These effects were even more pronounced among participants with more severe baseline problems and for participants who fully completed the course. The effects on work-related stress and quality of life were less clear. To our knowledge, this is the first trial of a Web-based, problem-solving intervention for people with different types of (comorbid) emotional problems. The results are promising, especially for symptoms of depression and anxiety. Further research is needed to enhance the effectiveness for work-related stress.

A pragmatic randomized controlled trial of a guided self-help intervention versus a waiting list control in a routine primary care mental health service

OBJECTIVES. To evaluate the effectiveness of a two session guided self-help (GSH) intervention provided by primary care graduate mental health workers (PCGMHWs) in a primary care mental health service. DESIGN. Pragmatic randomized trial, with a wait list control design. METHOD. Patients presenting with significant anxiety and depression problems were given one or more self-help booklets at screening and randomly allocated to an immediate (ITG) or delayed treatment group (DTG). Following this, a two-session GSH intervention was provided by one of two PCGMHWs, with a review session to decide on the need for further intervention. The DTG began the intervention 8 weeks after the screening and the primary outcome was Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM) scores after 8 weeks. RESULTS. A total of 63 patients were allocated to the ITG, 59 to the DTG. Analysis of covariance, carried out on an intention to treat basis, showed a significant treatment effect, F(1,98) = 15, p < .001, and a comparison of means at 8 weeks showed a significant difference, t(116) = 2.1 (95% CI [1.1, 5.9]), p= .042 with an effect size, d= 0.375. Taking the two groups together, CORE-OM scores for patients who completed the intervention reduced between screening and the review session by an average of 7.9 (95% CI [6.3, 9.5]), effect size of 1.2. Between screening and the review session, 47% showed a reliable and clinically significant improvement. CONCLUSIONS. The study provides some support for the effectiveness of a two-session GSH intervention and a stepped-care service model.     

Cognitive-behavioral therapy for women with lifelong vaginismus: a randomized waiting-list controlled trial of efficacy

Women with lifelong vaginismus (N=117) were randomly assigned to cognitive-behavioral group therapy, cognitive-behavioral bibliotherapy, or a waiting list. Manualized treatment comprised sexual education, relaxation exercises, gradual exposure, cognitive therapy, and sensate focus therapy. Group therapy consisted of ten 2-hr sessions with 6 to 9 participants per group. Assistance with minimal-contact bibliotherapy consisted of 6 biweekly, 15-min telephone contacts. Twenty-one percent of the participants left the study before posttreatment assessment. Intent-to-treat analysis revealed that successful intercourse at posttreatment was reported by 14% of the treated participants compared with none of the participants in the control condition. At the 12-month follow-up 21% of the group therapy participants and 15% of the bibliotherapy participants, respectively, reported successful intercourse. Cognitive-behavioral treatment of lifelong vaginismus was thus found to be efficacious, but the small effect size of the treatment warrants future efforts to improve the treatment.

Guided self-help for bulimia nervosa in primary care: a randomized controlled trial

BACKGROUND: To increase access to cognitive behavioural therapy for bulimia nervosa new delivery modes are being examined. Guided Self-Help (GSH) in primary care is potentially valuable in this respect. This research aimed to compare outcomes following GSH delivered by general practitioners (GPs) in the normal course of their practice to a delayed treatment control (DTC) condition, and to examine the maintenance of treatment gains at 3 and 6 months following completion of GSH. METHOD: Participants were 109 women with full syndrome or sub-threshold bulimia nervosa, randomly allocated to GSH ( n = 54) and DTC ( n = 55). The GSH group received direction and support from a GP over a 17-week period while working through the manual in Bulimia Nervosa and Binge-Eating: A Guide to Recovery by P. J. Cooper (1995). GSH and DTC groups were assessed pre-treatment and 1 week following the 17-week intervention or waiting interval. The GSH group was reassessed at 3- and 6-month follow-up. RESULTS: Intention-to-treat analyses at end of treatment revealed significant improvements in bulimic and psychological symptoms in GSH compared with DTC, reduction in mean frequency of binge-eating episodes by 60% in GSH and 6% in DTC, and remission from all binge-eating and compensatory behaviours in 28% of the GSH and 11% of the DTC sample. Treatment gains were maintained at 3- and 6-month follow-up. CONCLUSION: Outcomes in GSH compare favourably with those of specialist-delivered psychological treatments. These findings are considered in light of the nature of the therapy offered and the primary care context.

Management of miscarriage: a randomized controlled trial of expectant management versus surgical evacuation

BACKGROUND: In many countries, surgical uterine evacuation is the standard treatment for women with a miscarriage, but expectant management has been advocated as an alternative. The choice between the two options cannot be based on published evidence alone, because randomized clinical trials are scarce while generalizability of findings to patients with a strong preference for either management options is unclear. METHODS: In a randomized controlled trial, the complications and efficacy of either expectant or surgical management for miscarriages were compared, and the results in patients who refused randomization and were managed according to their own preference were studied. In total, 122 patients were randomized and 305 were managed according to their choice. RESULTS: No differences were found in the number of emergency curettages and complications between expectant and surgical management. Efficacy at 6 weeks was 30/64 (47%) in women allocated to expectant management, and 55/58 (95%) in women allocated to surgical evacuation. After 7 days, 37% of expectantly managed women had a spontaneous complete miscarriage. After 6 weeks, intention-to-treat analysis including cross-overs showed similar effectiveness (92% versus 100%). Results in the preference groups were comparable with those in the randomized groups. CONCLUSION: In our experience a waiting period of 7 days after diagnosis may prevent 37% of surgical procedures.     

Gender patterns in cost effectiveness of quality improvement for depression: results of a randomized, controlled trial

BACKGROUND: Little is known about gender differences in the costs and outcomes of primary care quality improvement strategies for depression. METHODS: Intent-to-treat analysis of data from a group-level controlled trial, in which matched primary care clinics in the US were randomized to usual care or to one of two interventions designed to increase the rate of effective depression treatment. One intervention facilitated medication management ("QI-Meds") and the other psychotherapy ("QI-Therapy"), but patients and clinicians could choose the type of treatment, or none. The study involved 46 clinics in 6 non-academic, managed care organizations; 181 primary care providers; and 375 male and 981 female patients with current depression. Outcomes are health care costs, quality-adjusted life years (QALY), depression burden, employment, and costs/QALY, over 24 months of follow-up. RESULTS: Relative to usual care, QI-Therapy significantly reduced depression burden and increased employment, for men and women; but QI-Meds significantly reduced depression burden only among women. Average health care costs increased 429 USD in QI-Meds and 983 USD in QI-Therapy among men; corresponding cost increases were 424 and 275 USD for women. The estimated cost per QALY for men ranged between 16,600 and 42,600 USD under QI-Therapy. For women, estimated costs per QALY were 23,600 USD or below for QI-Meds and 12,500 USD or below under QI-Therapy. LIMITATIONS: This study may be underpowered for some relevant outcomes, particularly costs. The study population is limited to patients who sought health care in primary care settings. CONCLUSIONS: Both men and women can benefit substantially from quality improvement interventions for depression in primary care. Results are particularly favorable for the QI-Therapy intervention.     

Stress management and multiple sclerosis: a randomized controlled trial

There is a well-established adverse reciprocal relationship between stress and multiple sclerosis (MS). However, stress management in these patients has been parsimoniously studied. In this parallel randomized controlled trial, relapsing-remitting MS patients were randomly assigned to undergo either an 8-week stress management program (n=31; relaxation breathing and progressive muscle relaxation, twice a day) or not (n=30). Self-reported validated measures were used to evaluate perceived stress, health locus of control, anxiety, and depression. Daily diaries of MS symptoms were also kept by patients. In patients in the intervention group, perceived stress and symptoms of depression were significantly decreased after 8 weeks of relaxation. Repeated measures analyses showed significant group-by-time interactions for both the number of weekly symptoms and the mean intensity per symptom. No other significant change was reported. We deem that our results should encourage future studies that will incorporate more objective clinical and laboratory outcomes.     

A pilot randomized controlled trial of a depression and disease management program delivered by phone

Background

Depression in medically ill patients occurs at twice the rate found in the general population. Though pharmacologic and psychotherapeutic interventions for depression are effective, response to treatment and access to care are barriers for this population. A multidimensional telehealth intervention was designed to focus on these barriers by delivering a phone based intervention that addressed managing one's illness and coping emotionally.

Methods

Veterans with diabetes, hypertension, or chronic pain and depressive symptoms were randomized to one of three conditions: Usual Care (n=23), Illness Management Only (n=31), or Combined Psychotherapy and Illness Management (n=29). Those randomized to the Combined or Illness Management Only intervention group received 10 phone visits. Veterans in the Combined group received all aspects of the illness management program plus a manualized depression intervention. Subjects completed assessments at baseline, week 5, and 10 to test the main hypothesis that veterans in the Combined condition would have a greater decline in depressive symptoms.

Results

The Combined intervention yielded a significant decline in depressive symptoms when compared with Usual Care. However, the there was no significant difference between the Combined and Illness Management Only groups.

Limitations

This is a pilot study with a small sample size relative to a standard randomized controlled trial in psychotherapy.

Conclusions

This telephone-based intervention succeeded in reducing depressive symptoms in veterans with chronic illness. It adds to the building evidence base for providing phone-delivered mental health services.     

Cognitive self-therapy for chronic depression and anxiety: a multi-centre randomized controlled study

BACKGROUND: Non-professional treatment programmes are presumed to relieve the extensive need for care of anxiety and depression disorders. This study investigates the effectiveness of cognitive self- therapy (CST) in the treatment of depression or generalized anxiety disorder. METHOD: Patients (n=151) were randomized to receive CST or treatment as usual (TAU) in a trial lasting for 18 months, measuring symptoms (SCL-90; main outcome), social functions, quality of life and utilization of care. RESULTS: Patients in both conditions improved significantly, but no difference was found between the conditions. Reduction of symptoms, improvement of social functions and medical utilization were maintained at the end of the 18 months. Medical care utilization (therapist contact and hospitalization) was lower for CST than for TAU. No suicides occurred. CONCLUSIONS: Cognitive self-therapy is likely to decrease the need for care of chronic depression and anxiety disorders, but it has not been proven to be more effective than treatment as usual.     

Self-help materials for anxiety: a randomized controlled trial in general practice.

The efficacy of a self-help package in treating chronic anxiety was evaluated in a randomized controlled trial in which the intervention group received self-help materials in the form of an audiotape and booklet, in addition to their current treatment. The intervention was successful in terms of mean depression scores (P = 0.01), anxiety scores (P = 0.04) and general health questionnaire scores (P = 0.02) which were significantly lower for the intervention group than for the controls. In addition, the depression scores fell faster for the intervention group than for the controls. The overall mean reduction in three months in adjusted depression scores was approximately two points greater for the intervention group than for the controls (P = 0.02). Clinicians welcomed the package as a valuable addition to the therapies available for managing chronic anxiety problems. Further studies should include larger sample sizes, taking into account the non-response to postal questionnaires over time.
