CONSORT-EHEALTH Checklist V1.6.2 Report

1b-i) Key features/functionalities/components of the intervention and comparator in the METHODS section of the ABSTRACT "Based on the behavioural graded activity treatment, we developed a web-based intervention to improve PA levels in patients with knee and/or hip OA, entitled Join2move. The Join2move intervention is a self-paced nine week PA program in which patients’ favourite recreational activity is gradually increased in a time-contingent way. " 1b-ii) Level of human involvement in the METHODS section of the ABSTRACT yes, in the objective section of the abstract we mentioned the level of human involvement. "a fully automated web-based PA intervention" 1b-iii) Open vs. closed, web-based (self-assessment) vs. face-to-face assessments in the METHODS section of the ABSTRACT " Volunteers were recruited via articles in newspapers and health-related websites" "Baseline, 3 and 12 months follow-up data were collected through online questionnaires. " "In a subgroup of participants, PA was measured objectively using accelerometers. " Bliding was not possible since we compared an intervention with a waiting list control group 1b-iv) RESULTS section in abstract must contain use data "Of the 581 interested respondents, 199 eligible participants were randomly assigned to the intervention (n=100) or waiting list control group (n=99). Response rates of questionnaires were 84.4% after 3 months and 75.4% after 12 months. In this study, 94 (94%) participants actually started the program and 46 users (46%) reached the adherence threshold of 6 out of 9 modules completed. " 1b-v) CONCLUSIONS/DISCUSSION in abstract for negative trials "Join2move resulted in changes in the desired direction for the primary outcome measures physical function (short term) self-perceived effect (long term). Given the benefits and its self-help format, Join2move could be a component in the effort to enhance PA in sedentary patients with knee and/or hip OA. " INTRODUCTION 2a-i) Problem and the type of system/solution "Therefore, PA as a non-pharmacological intervention has been advocated in the treatment of OA patients [9]. " "Numerous patients lack knowledge and skills to modify their PA routines and have negative concerns (e.g. fear of pain and catastrophizing thoughts) about the impact of PA on their joints [15,16]. " "To date, there are no web-based PA interventions for patients with knee and/or hip OA. Given the advantages of internet and its unique ability to reach outside care patients with knee and/or hip OA, we developed Join2move. " 2a-ii) Scientific background, rationale: What is known about the (type of) system "Web-based interventions are applications available through a website with the aim to enhance understanding of a health condition and to change health behavior. Particularly, web-based interventions with minimal human contact have the potential of high reach, low costs and are accessible anytime and anywhere [19]. Previous studies among general inactive populations and patients with a chronic disease (e.g. diabetes, cardiovascular diseases and chronic obstructive pulmonary disease) have produced mixed findings regarding the effectiveness of web-based PA interventions [2022]. " METHODS 3a) CONSORT: Description of trial design (such as parallel, factorial) including allocation ratio "This study aimed to answer the following research question: “What is the effectiveness of the Join2move intervention in patients with knee and/or hip OA on PA, physical function and self-perceived effect in comparison with a waiting list control group? ”" 3b) CONSORT: Important changes to methods after trial commencement (such as eligibility criteria), with reasons NA 3b-i) Bug fixes, Downtimes, Content Changes yes, we included the following sentence in the method section: "No content changes were made during the trial period. " 4a) CONSORT: Eligibility criteria for participants "The eligibility criteria for participants were (i) age 50-75, (ii) self-reported OA in knee and/or hip, (iii) self-reported inactivity (<30 minutes of moderate PA three five times or less per week), (iv) no face to face consults for OA with a healthcare provider, other than GP, in the last 6 months, (v) ability to access the internet weekly and (vi) and no contra-indications to exercise without supervision. " 4a-i) Computer / Internet literacy See comment 4a 4a-ii) Open vs. closed, web-based vs. face-to-face assessments: "Patients with self-reported knee and/or hip OA were recruited through advertisements in Dutch newspapers and online health-related websites. " 4a-iii) Information giving during recruitment "Patients with self-reported knee and/or hip OA were recruited through advertisements in Dutch newspapers and online health-related websites. The advertisements briefly explained the purpose of the project and beneficial health effects of PA.Interested individuals were referred to an open access study website and invited to complete an online eligibility questionnaire. Participants’ mail addresses were used to contact participants for online followup questionnaires and home addresses were used for sending an information letter, informed consent form and accelerometer. " "After randomization, all participants were informed through e-mail of their group assignment" 4b) CONSORT: Settings and locations where the data were collected
