Study characteristics
Methods	Study design: randomised controlled trial Study grouping: parallel group Duration of study: 9 weeks Randomisation method: lottery method Allocation concealment method: no information Blinding of outcome assessors: no information Adequate power (evidence of power calculation): no information Check of blinding: no information
Participants	Baseline characteristics Intervention n: 9 Duration of symptoms: max 6 months Control n: 9 Duration of symptoms: max 6 months Overall n: 18 Age (mean): 22.22 (SD 2.7) years Sex (% woman): 83.3% Ethnicity: 16 (88.8%) rural Marital status currently married, n (%): 14 (77.7%) Educational status: 6 (33.3%) primary, 10 (55.5%) secondary and 4 (11.1%) had higher secondary level. 2 (11.1%) were working and 16 (88.8%) were not working or were house wives Inclusion criteria: people diagnosed with conversion disorder (having pseudo seizures only) as per ICD‐10 criteria thoroughly investigated having no comorbid psychiatric or physical illness and whose total duration of illness was not > 6 months, of both sexes, aged 18 to 50 years. Exclusion criteria: all dissociative (conversion) disorders other than fits (pseudo seizures), aged < 18 years and > 50 years and those who did not consent. Pretreatment: no statistically significant differences at baseline between groups
Interventions	Intervention characteristics Intervention Description: behavioural therapy, 15 sessions (7 inpatients and 8 follow‐ups) + training of carers for 1 week. Length of treatment: 9 weeks Longest follow‐up after end of treatment: none Comedications/other treatments while in the study: inpatient SC for 1 week Control Description: routine TAU (pharmacotherapy) and were observed by the psychiatrists at outpatient department. Length of treatment: unclear Longest follow‐up after end of treatment: none Comedications/other treatments while in the study: none
Outcomes	Number of weekly seizures Outcome type: continuous Direction: lower is better Data value: endpoint Mental state – anxiety (HADS) Outcome type: continuous Data value: change from baseline Notes: HADS subscale Anxiety Mental state – depression (HADS) Outcome type: continuous Notes: HADS – subscale Depression Dropout Outcome type: dichotomous Data value: endpoint
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Quote: "They were than randomly assigned to the behavior therapy (n=9) and control group (n=9) by lottery method."
Allocation concealment (selection bias)	Unclear risk	Nothing information provided.
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	The control was commented on. It was unclear with the intervention group, and the personnel.
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	No information provided.
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	All data were reported, including dropout rates. The distribution of dropout was similar across groups (1 vs 3), but the reasons for dropout were not specified, neither was the time point for dropout.
Selective reporting (reporting bias)	Unclear risk	No protocol provided.
Other bias	Low risk	No other apparent sources of bias.
