Abstract:This study investigated if both, psycho-social factors and adherence correlated with the effect of a guided online ACT intervention. Further it tested if adherence had such a central role in the mechanism of change as postulated by the Internet Intervention Model by (Ritterband, Thorndike, Cox, Kovatchev, & Gonder-Frederick, 2009). Therefore, a mediation model was tested with psycho-social factors as predictors for the effectiveness of the intervention and adherence as a possible mediator. This study was a follow-up on a RCT on the intervention ‘living with pain’. People suffering from chronic pain participated in an online intervention which consisted of nine modules and had to be completed within 12 weeks. People were expected to work with the intervention for at least 3 hours a week and were supported by weekly e-mail counseling. The modules of the intervention were based on the six ACT processes and included for example psycho-education, mindfulness exercises and exercises to identify and implement personal values. Results in this research showed that pain catastrophizing and psychological inflexibility were the only psycho-social factors which correlated significantly with the change in pain interference (effect) from baseline to three months after the intervention. Mental health, depression and anxiety did not correlate significantly with the change in pain interference. Furthermore the results revealed that adherence did not mediate that correlation. Contrary to the expectation based on the Internet Intervention Model by Ritterband et al. (2009), adherence did not show any significant correlation with either psycho-social factors or change in pain interference (effect). Further research should investigate if the Internet Intervention Model is more accurate if user characteristics are arranged side by side with website use. Beside that the criteria for adherence should be reconsidered, it is advisable to include how concentrated or intensive participants worked with the intervention.
