Feasibility of the Internet-delivered Treatment SpilleFri for Patients With Pathological Gambling

Study Overview
=================
Brief Summary
-----------------
This uncontrolled feasibility pilot study explores the feasibility of a 10 week, 8-module, therapist-assisted, internet-delivered treatment program, SpilleFri, for patients with Pathological Gambling. The study includes 25-30 participants aged 18-60 fulfilling diagnostic criteria for Pathological Gambling (ICD-10). The focus of the feasibility trial is evaluation of treatment response, treatment satisfaction, program utility, recruitment and retention rates, data completion rates, and time requirement. The primary feasibility criterion is 60 % of participants included in the study completing the treatment program.

Detailed Description
-----------------
SpilleFri - an Internet-delivered Treatment for Patients with Pathological Gambling. A Feasibility Pilot Study Lisbeth Frostholm & Anna Stenbro Objective The objective of this uncontrolled pilot study is to test the feasibility of a future RCT by exploring the feasibility of an internet-delivered treatment program, SpilleFri, for patients with Pathological Gambling. The focus of the feasibility trial is evaluation of treatment response, treatment satisfaction, program utility, recruitment and retention rates, data completion rates, and time requirement. The primary feasibility criterion is an a priori defined change in patient-rated gambling problems from before to after treatment. Design This study is designed as an uncontrolled, single-arm, single-center feasibility pilot study. Participants The study includes 25-30 participants included from September 2021 to March 2022. The participants are recruited from The Research Clinic on Gambling Disorder, Aarhus University Hospital, Denmark. Patients with Pathological Gambling are screened for eligibility by the eligibility criteria below. They undergo thorough diagnostic assessment by an authorized psychologist including diagnostic interview (Schedules for Clinical Assessment in Neuropsychiatry). Intervention SpilleFri is a newly developed internet-delivered therapist-assisted treatment program for patients with Pathological Gambling. The 8 modules contain text, video files with psychoeducation, guided exercises, and videos with former patients. During a period of 10 weeks, patients are guided through the program modules assisted by a trained psychologist. Course If eligible and willing to participate, patients are included in the pilot study and assigned to a therapist (a trained psychologist from The Research Clinic on Gambling Disorder). Patients are contacted by telephone by the therapist and guided to login to the program platform and initiate treatment. The therapist follows the patient through the 8 treatment modules and provides guidance when needed. Patients and therapists primarily communicate through asynchronously written messages. If deemed necessary by the therapist, up to four consultations (telephone-/video-based or with physical attendance at the clinic) may be offered to enhance patient motivation and/or treatment adherence and effect. Treatment duration is 10 weeks. Measurements Patient-rated outcome measures are collected through a web-based program at the time of screening (before inclusion) (T1), before treatment (T2), and at end of treatment (T3). Between 6 and 12 patients will be interviewed during and post treatment to assess patient experience and satisfaction with the treatment program. Clinician ratings are collected at the time of diagnostic assessment and at end of treatment. Measurements also include logged data from the SpilleFri-treatment internet program, e.g. regarding patient activity in the program and number of messages to/from therapist pr. patient. Feasibility outcomes Recruitment and retention rates, time requirements and data completeness as measured by the rate of eligible patients willing to participate, the rate of included patients completing the treatment program (defined as completion of at least 5 modules), therapists' time spent per patient, and the rate of treatment completers providing full data Patients' impression of treatment effect as measured by the clinical global improvement scale (CGI_p) Patients' treatment satisfaction and assessment of program utility as measured by the credibility/expectancy questionnaire and a purpose designed patient satisfaction questionnaire Therapists' impression of treatment effect as measured by the clinical global improvement scale (CGI_c). Changes in patient-rated gambling problems from before to after the treatment measured by the NODS Feasibility criteria The investigators regard a future study testing the treatment program SpilleFri in an RCT as feasible if: 60 % of the patients included in the study complete the treatment program (defined as completion of at least 5 of 8 modules) 70 % of treatment completers provide data for primary gambling outcome variable (NODS)

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Internet-delivered treatment: SpilleFri.<br>All participants receive the internet-delivered therapist-assisted 8-modules treatment program SpilleFri. | Behavioral: Internet-delivered treatment: SpilleFri.<br>* The guided internet program consists of 8 modules over a period of 10 weeks. The content is written psychoeducation, videos with patients and experts, and exercises (encouraging reflection, cognitive restructuring, and exposure). The program is therapist-guided; hence all patients will receive support primarily from a specific therapist during the 10 weeks.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Feasibility: Recruitment and retention rate | Data will be gathered throughout the study to assess feasibility, defined herein as the extent to which the intervention can be successfully delivered. Primary feasibility outcome is recruitment and retention rate, collected through clinic records and therapist report in web-based questionnaire. | Weekly during the intervention, up to 14 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Feasibility: Contact with therapist pr. patient | Collected through therapist report in web-based questionnaire and logged data from the treatment program SpilleFri. | Weekly during the intervention, up to 14 weeks | 
| Feasibility: Patient activity in treatment program (log-in time and duration, yielding total minutes spend in treatment program) | Collected through logged data from the treatment program SpilleFri | Weekly during the intervention, up to 14 weeks | 
| Treatment expectancy and satisfaction | Measured by the credibility/expectancy questionnaire. 6 items rated on a 1-9 or a 0%-100% scale, depending upon the item. The scale yields a mean expectancy score, ranging from maximum 100 % to minimum 0 %. Self-report collected through a web-based questionnaire program | Immediately after inclusion in treatment. Before first treatment session | 
| Treatment expectancy and satisfaction | Measured by the credibility/expectancy questionnaire. 6 items rated on a 1-9 or a 0%-100% scale, depending upon the item.

Self-report measure collected through a web-based questionnaire program. For the purpose of the study, the NODS is modified to assess the last month instead of the last year.
