Detailed Description
This study centers on people with mild symptoms of stress or worry. Participants are recruited by advertisement and the web. Potential participants are contacted by phone and informed about the study. Written informed consent is collected through mail from those who are interested in participating. They are asked to answer all the instruments of the study via a secure internet portal used for delivering the intervention. If they do not fulfill the exclusion criteria they are randomized to one of four conditions. When the intervention has ended participants are asked to fill out all the instruments and again at four week follow up. To find significant (p<.05) results on the primary outcome variables with estimated medium effect sizes, pair-wise comparisons, a power of .80 and allowing for 10% attrition, forty participants are needed in each condition.
The intervention used in this project will be a standard program of applied relaxation that has been used and empirically tested in previous clinical studies. Since the aim of the present project is to investigate factors that affect adherence rather than the intervention effect, the investigators will use a well tested intervention with known effects on symptoms of stress and anxiety. Previous studies have shown that self help with applied relaxation can have a positive effect on for example stress, anxiety and sleep. By providing an intervention that is beneficial, credible and relevant for people with mild symptoms of stress and anxiety it would be possible to investigate how manipulating different factors of the intervention affects the adherence. Applied relaxation will in this intervention consist of a four-week program provided via the Internet. The exact composition of the intervention will be slightly different in each condition depending on the research question, see below. The program includes four steps; tension sensitivity training, long relaxation, short relaxation and applied relaxation. Each week includes information, assignments and support via the secure internet portal.
