NCT05946382

Brief Summary

This pilot randomized controlled trial evaluated the feasibility of a Swedish translation of an Acceptance and Commitment Therapy protocol targeting repetitive negative thinking (RNT-ACT) compared with therapist-supported internet-based cognitive behavioral therapy (iCBT) in Swedish primary care. Feasibility was assessed in terms of recruitment, intervention completion, and patient satisfaction. Symptoms of depression, anxiety and stress, rumination, psychological flexibility, valued living, and cognitive fusion were assessed as secondary outcomes.

Outcome Measures

Primary Outcomes (3)

  • Recruitment rate

    Percentage of participants enrolled among all individuals screened for participation. Calculated as the number of participants enrolled divided by the total number of individuals screened, multiplied by 100.

    At screening and enrolment.

  • Intervention non-completion rate

    Percentage of randomized participants who did not complete their allocated intervention. Intervention completion was assessed as a binary outcome.

    From randomization through completion of the allocated intervention, up to approximately 3 months.

  • CSQ-8

    Client Satisfaction Questionnaire (CSQ-8). Min 8, Max 32 with higher values indicating higher satisfaction.

    At the main post-treatment follow-up; if not completed, at the 3-month follow-up.

Secondary Outcomes (5)

  • DASS-21

    At baseline, main post-treatment follow-up, and 3-month follow-up.

  • RRS-BR

    At baseline, main post-treatment follow-up, and 3-month follow-up.

  • SAAQ

    At baseline, main post-treatment follow-up, and 3-month follow-up.

  • Valuing Questionnaire (VQ)

    At baseline, main post-treatment follow-up, and 3-month follow-up.

  • CFQ-7

    At baseline, main post-treatment follow-up, and 3-month follow-up.

Study Arms (2)

RNT-ACT protocol

EXPERIMENTAL

Participants randomized to RNT-ACT will receive a total of 2 sessions of 60 minutes each as well as audio files to listen to between the occasions administered via internet. Previous studies have indicated that it doesn't make much of a difference whether the temporal distance between session 1 and session 2 is between 1 week and up to 3 months. At occasion 1, the time for occasion 2 is set. The temporal distance in days will noted for each patient. The treatment is inserted into the therapist's regular diary with 60 minutes session time and appropriate break before and after the treatment (e.g. at least 5-10 minutes) for preparation and post-administration where journal writing is included.

Behavioral: RNT-ACT Protocol

iCBT treatment

ACTIVE COMPARATOR

The people randomized to Internet treatment will be offered based on M.I.N.I 7.0 a suitable iCBT program in the Stöd och Behandling (SoB) platform. The patients follow a structured self-help material which can be seen as a standard treatment option in Region Skåne, "treatment as usual". The therapist has access to the material and the patient and the therapist can communicate via a chat function. The patients are matched to iCBT programs based on whether they are most likely to show symptoms of depression or anxiety. The main component of Internet processing consists of a structured self-help program in approximately eight modules, somewhat varying depending on which program in use. The program is based on proven CBT interventions for each problem area with a strong emphasis on psychoeducation but where different intervention elements is included.

Behavioral: iCBT Treatment
