Website-Based Self-Help for Women With Anxiety After Childbirth

Feasibility of a Web-Based Intervention for Women With Postpartum Anxiety: A Randomized Controlled Trial

This study examines the feasibility and acceptability of a web-based intervention program for women with anxiety after childbirth, potential anxiety reduction after the intervention and determines the feasibility of the study design (randomized controlled design) and recruitment for the intervention in this population to inform the protocol (including effect size and study power) for a randomized controlled trial.

Study Overview

• Status: Completed
• Conditions: Anxiety Disorders
• Intervention / Treatment: Behavioral: internet-What Am I Worried About

Detailed Description

Background: What Am I Worried About (WAWA) is a self-help booklet intervention for women experiencing anxiety after birth based on cognitive-behavioural and mindfulness principles developed in Australia. The WAWA booklet was found to be acceptable, safe, stigma free, feasible, and demonstrated preliminary efficacy in Australia. A web-based version of WAWA for the use in the United-Kingdom (UK) was developed at City University London in collaboration with the intervention development team in Australia. However, before dissemination the web-based version of WAWA (iWAWA) in the UK it is deemed important to evaluate the program. Therefore, this study aims to examine the feasibility, acceptability, and potential efficacy of this web-based intervention program for women with anxiety after childbirth in the UK.

The primary objectives of the proposed study are to:

conduct a randomized controlled trial and

• examine the feasibility of web-based treatment program (iWAWA) in terms of engagement and usability.
• examine user's acceptability of iWAWA in terms of usefulness, satisfaction, and credibility.

The secondary objectives of this study are to:

• obtain initial estimates of anxiety levels and examine potential patient improvement over the course of the intervention and compared to the control group.
• determine the feasibility of the study by examining recruitment, consent, attrition, follow-up rates, as well as response rates to questionnaires.

Method: For this feasibility study, an embedded mixed methods design is employed utilizing both quantitative and qualitative methods to achieve the above stated aims. For the quantitative part, a randomized control trial is conducted. Outcomes are assessed at pre-intervention, throughout the intervention, post-intervention, and 1-month post-intervention. For the qualitative part, semi-structured interviews are used for a more in-depth exploration of acceptability and feasibility of the iWAWA intervention. The interviews with participants are carried out post intervention.

Study benefits: Based on the participants' feedback, this study hopes to inform development and adaptation of the investigated web-based intervention. If the interventions acceptability and feasibility is confirmed, the next steps would be to test the intervention efficacy in a stage II randomized control trial.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Web-based intervention; Participants get access to the web-based intervention and are asked to work through the 8 modules of the intervention within eight weeks. The intervention program sends automated weekly email reminders about the current session. In addition, users are offered weekly optional 30-minute telephone support with a trained intervention coach.	Behavioral: internet-What Am I Worried About; This web-based intervention consists of three sections: 1) Is this for me? 2) Practice 3) Understanding. The three main sections are divided up into nine sessions. Participants will get access to the program for eight weeks and can access the sessions more than once. Sessions are made up of multimedia presentations and worksheets that are completed online.
No Intervention: Wait-list control; Participants get standard care and will be offered access to the web-based intervention at 8-weeks post-randomization.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Engagement as measured by the number of log-ins into the web-based intervention		At time of intervention (8 weeks)
Engagement as measured by the duration of log-ins into the web-based intervention		At time of intervention (8 weeks)
Engagement as measured by the total duration of time spent on the web-based intervention		At time of intervention (8 weeks)
Engagement as measured by the time spent on individual pages of the web-based intervention		At time of intervention (8 weeks)
Engagement as measured by the number of intervention coach calls		At time of intervention (8 weeks)
Usability as measured by participant's report of usefulness ("I found this module useful.") of each intervention module on a 7-point Likert scale (1 = strongly disagree to 7 = strongly agree).		At time of intervention (8 weeks) after each completed intervention module
Usability as measured by participant's report of clarity ("This module was clear and understandable.") of each intervention module on a 7-point Likert scale (1 = strongly disagree to 7 = strongly agree).		At time of intervention (8 weeks) after each completed intervention module
Usability as measured by participant's report of usability on the System Usability Scale (SUS)	The System Usability Scale (SUS) is a 10-item instrument rated on 5-point Likert scale (1 = strongly disagree to 5 = strongly agree) and participants are asked to rate the degree to which they agree with positive and negative descriptions of a program. The SUS will be adapted for this study by replacing 'the system/product' with 'iWAWA' for all items. Higher scores indicate better usability.	Within 2 weeks after the intervention
Usability as measured by participant's report of usability on a series of items designed to measure ease-of-use and unobtrusiveness on 7-point Likert scale (1 = strongly disagree to 7 = strongly agree)		Within 2 weeks after the intervention
Usability as measured by participant's report of any technical problems experienced with the intervention website		Within 2 weeks after the intervention
Usability as measured by participant's report of interest in future usage of the intervention		Within 2 weeks after the intervention
Usefulness as measured by participant's report of a series of items designed to measure perceived usefulness on a 7-point Likert scale (1 = strongly disagree to 7 = strongly agree).		Within 2 weeks after the intervention
Satisfaction as measured by participant's report of a series of items designed to measure perceived satisfaction on a 7-point Likert scale (1 = strongly disagree to 7 = strongly agree).		Within 2 weeks after the intervention
Satisfaction as measured by participant's report on the Client Satisfaction Questionnaire (CSQ-8)	The Client Satisfaction Questionnaire (CSQ-8) will further be used and adapted to assess satisfaction. The CSQ-8 consists of eight items which are rated on 5-point Likert scale. The CSQ-8 will be adapted for this study by substituting 'service' with 'help" and "program" with "iWAWA" in all items.	Within 2 weeks after the intervention
Credibility as measured by participant's report on the first 4 items of Credibility/ Expectancy Questionnaire (CEQ)	The Credibility/ Expectancy Questionnaire (CEQ) is a 6-item widely applied measure of the expectancies or perception of intervention credibility and will be adapted for the use in this study.	Within 2 weeks after the intervention
Women's perspectives and experiences as measured by semi-structured interviews		Within 8 weeks after the intervention
Engagement as measured by the duration of intervention coach calls		Continuous throughout the 8 week intervention period
Usability as measured by participant's report of hypothetical recommendation of the intervention to others.		Within 2 weeks after the intervention
