Feasibility and acceptability of ACASI, and a comparative analysis of enrolment responses between ACASI and FtF on an identical risk assessment questionnaire were evaluated.
Self-reported 7-day and 30-day abstinence assessed at 6-month and 12-month post-enrolment (response rates: 61% and 59%, respectively).
The sampling frame, enrolment methodology and response rates for this cross-sectional survey are described elsewhere in detail [ 10- 13].
Follow-up, using a structured pro forma document, included clinical assessment, monitoring for opportunistic infections (in HIV-positive patients), routine blood investigations, sputum smear and culture if appropriate and possible, and repeat imaging as at enrolment to monitor response to treatment.
This resulted in a target enrolment of 35 response-evaluable patients in each study.
Of 16 patients with SD during the study period, 10 had PD, five had SD, and one had partial response before enrolment.
Response rate (enrolment of subjects), retention rate (number and proportion attended each class) of the MBCT and the psycho-education group will be documented.
Enrolment criteria included inadequate response to stable methotrexate (MTX) therapy, exemplified by a swollen joint count (SJC) ≥6 and a tender joint count (TJC) ≥6, together with C-reactive protein (CRP) >10 mg/L or erythrocyte sedimentation rate (ESR) >28 mm/h.
In terms of course participants, while the response to enrolment, contact sessions and the use of course material have been very encouraging, the challenge has been to motivate participants to undertake projects and assignments, especially due to the absence of any current formal accreditation.
The primary risk factors of interest were TST and ELISPOT responses at enrolment.
Non-response at enrolment and lost to follow-up would lead to biased effect estimates if the associations of air pollutants with wheezing would be different between those included and not included in the analyses.
