A number of well-described controlled studies assessing cancer support
group intervention support their effectiveness. All of these experime
ntal groups have been close-ended and typically involve sir to eight w
eekly sessions. Because many cancer patients are unable or unwilling t
o participate in closed extended-session groups, there is particular n
eed for analysis of the effectiveness of shortterm, open-ended groups.
Additionally, objective measures are needed to delineate the factors
contributing to a successful outcome in cancer support groups. We used
the Short Form of the Group Climate Questionnaire (GCQS) to character
ize 23 sessions in an open-ended, short-term, Veterans Hospital based
cancer support group. The cancer group scored significantly lower on t
he Avoiding and Conflict dimensions (p <.001) compared to a normative
psychotherapy group sample. There was no difference on the Engaged dim
ension. This pilot study suggests that a cancer support group in this
setting can create an environment where members are cohesive and take
responsibility for their own change process, while keeping interperson
al conflict to a minimum. Based on these preliminary findings, we enco
urage controlled clinical trials examining the efficacy of open-ended
cancer support groups.
