OBJECTIVE: To evaluate the efficacy of a psychological treatment to reduce
moderate to severe hopelessness after severe traumatic brain injury (TBI).
METHOD: Randomized controlled trial. Participants were aged between 18 and 65
years, experienced posttraumatic amnesia more than 1day and moderate to severe
hopelessness (Beck Hopelessness Scale [BHS]) and/or suicide ideation.
Intervention comprised a 20-hour manualized group cognitive behavior therapy
program. Participants were randomly allocated using concealed allocation
(treatment n = 8; wait-list n = 9); all remained in their allocated group.
Outcome variables were collected by assessors blind to group allocation. RESULTS:
No between-groups differences were observed on demographic, injury, cognitive,
and psychosocial variables at baseline (time 1). A significant group-by-time
interaction was found for BHS in the treatment group (F1,15 = 13.20, P = .002),
reflecting a reduction in mean BHS scores between time 1 and time 2
(posttreatment) with no main effects for group or time. At 3-month follow-up
(time 3), the treatment gains were maintained or improved for 75% (6/8) of
participants. Secondary outcome variables (suicide ideation, depression, social
problem solving, self-esteem, hopefulness) displayed no significant group-by-time
interactions or main effects. CONCLUSIONS: This trial provides initial evidence
for the efficacy of a psychological intervention in reducing hopelessness among
long-term survivors with severe TBI.
