the purpose of this study was to explore if a psychological treatment fusing act and cft principles and therapeutic techniques could improve outcome in chronic pain patients with high levels of self-criticism in comparison to a wait-list control group. the treatment was delivered via the internet, guided by trained professional. internet delivered cognitive behavior therapy (cbt) and act treatments have shown similar efficacy as compared to face-to-face treatments in a variety of problem areas and across a large range of outcomes. participants were recruited from a clinical setting. the treatment program consisted of eight sections and was based on a manual based on act developed for chronic pain (buhrman et al., 2013) and a cft-manual for chronic pain. following a screening interview participants deemed eligible were asked to complete an assessment battery online. all correspondence concerning treatment was held through a web portal including the online questionnaires and a secure e-mail service. the system handled security issues with two factor authentication. the participants logged in with electronic identification which is a secure service used by banks and in clinical settings. measures were obtained pre- and post- intervention and administered via the internet. a sixth month follow-up of the treatment group was administered. mediation measures were also obtained.
