A longitudinal comparative study of a multicouple group and single-couple psychosocial intervention while experiencing infertility.

This is a quasi-experimental, nonequivalent design study investigating the efficacy of multicouple group and single-couple intervention formats aimed at diminishing the psychosocial impact of infertility. The review studies carried out to date that have assessed this subject do not show consistent findings and although increasing the efficacy and efficiency of intervention formats more than justifies their analysis, there are no studies making this particular comparison. Eighty-seven infertile couples who were in assessment for their infertility and/or were close to undergoing some kind of assisted reproductive technology process participated in a psychosocial intervention either under the multicouple group or single-couple subconditions, or acted as controls. The variables of depression, anxiety, and fertility quality of life were used for evaluating psychosocial impact. Comparisons were made: (a) between the intervention condition and controls and (b) between the two subconditions. The results support the efficacy of the intervention both in the dyadic latent growth curve models analysis carried out and in the treatment effect calculation. Although in the comparison between the multicouple and single-couple format, some differences generally favoring the single format one were found, they were not conclusive. Therefore, the results are in line with review studies that did not find the group format to be more effective. Although this study provides valuable information, its limitations mean that further research needs to be carried out. When selecting the intervention format, therapists should also weigh up others aspects, such as the intervention goal, patient's needs and characteristics, reproductive history, and current stage of infertility.
