Study summary

The purpose of the study is to investigate the efficacy of an internet-based self-help intervention for dealing with stressful life events.

Read the detailed description

The purpose of the study is to investigate the efficacy of an internet-based self-help intervention for dealing with stressful life events compared to a waiting list, in a randomized controlled trial design. Assessments are at baseline, 4-week and 3 months post-randomization. After 4 weeks, participants in the waiting control group get also access to the intervention.

Interventions

  • OtherInternet-based self-help program

    The intervention provided is based on the principles of cognitive behavioral therapy (CBT) (Bachem \& Maercker, 2013). The manual integrates a variety of approaches validated as treatments for PTSD, anxiety disorders, or depression; the selection focuses on exercises which are intended to target the main symptoms of AjD, namely preoccupations (e.g. constant rumination, excessive worry about the stressor) and failure to adapt (e.g. sleep disturbance, difficulties concentrating, loss of interest in previously enjoyable activities).

What researchers measure

Primary outcomes

  1. Adjustment Disorder - New Module 20 (ADNM-20)

    The ADNM-20 is a self-report assessment for adjustment disorder. It is aimed at adults who feel burdened by a critical life event. The ADNM-20 consists of two parts: an event list for recording stress and an item list for recording the resulting symptoms. In the event list, all burdens during the last two years are recorded and the subjectively highest burdens are named. On the basis of the item list, preoccupations and mismatch, the main symptom groups of the adaptation disorder according to ICD-11, as well as the concomitant symptoms of avoidance, depressiveness, anxiety, impulse control problems and functional impairment are recorded. The scale ranges from 0 (no stress) to 80 (high exposure).

    Time frame: 4-week

Secondary outcomes

  1. Brief Symptom Inventory - Short Version (BSI-18)

    The short version of the Brief Symptom Inventory (BSI-18) is an easily applicable, reliable and valid self-report measure in wide international use. It assesses the syndromes of somatisation, depression and anxiety by means of 6 items each. The global factor ranges from 0 (no symptoms) to 72 (high symptomatic burden).

    Time frame: 4-week

  2. Beck Depression Inventory (BDI)

    The BDI is a 21-question multiple-choice self-report inventory, one of the most widely used psychometric tests for measuring the severity of depression. The score ranges from 0 (no symptoms) to 63 (severe depression).

    Time frame: 4-week

  3. Short Form 12-Item Survey (SF-12)

    The SF-12 consists of 12 questions and is a general health questionnaire that provides information on the patient's state of health in more than 8 different dimensions. Physical and Mental Health Composite Scores (PCS \& MCS) are computed using the scores of twelve questions and range from 0 to 100, where a zero score indicates the lowest level of health measured by the scales and 100 indicates the highest level of health.

    Time frame: 4-week

  4. Sense of Coherence Questionaire Revised (SOC-R)

    The SOC-R is a new conceptualization and operationalization of the resilience indicator SOC. The total score ranges from 13 (low) to 65 (high SOC).

    Time frame: 4-week

  5. Questionnaire for measuring patient satisfaction (ZUF-8)

    The ZUF-8 is a self-assessment tool to assess the patient's satisfaction with regard to aspects of the clinic and treatment. The scale ranges from 8 (bad) to 32 (good satisfaction).

    Time frame: 4-week

  6. Credibility/Expectancy Questionaire (CEQ)

    The CEQ is a scale for measuring treatment expectancy and rationale credibility for use in clinical outcome studies. The CEQ utilizes two scales during the administration (1-9, and 0-100%).

    Time frame: 4-week

  7. System Usability Scale (SUS)

    The System Usability Scale (SUS) is a simple and technology-independent questionnaire to evaluate the usability of a system. The score ranges from 0 (worst) to 100 (best).

    Time frame: 4-week
