ResultsThe odds ratio for pregnancy in the psychological intervention condition = .83, 95% CI [.75, .93]. The results also showed that the longer an intervention's follow-up period was, the less the prevention effect. Quality assessment of included studies indicated that all used a treatment manual and reported attrition. It also showed that most studies reported the reasons for drop-out and assessed the facilitators' adherence to the intervention protocol. The proportion of variability due to chance amongst studies was I2 = 22%. Duval and Tweedie's Trim and Fill showed a difference between the observed and the adjusted values. The adjusted value, representing a conservative estimate of effect size, was OR = .891, 95% CI [.777, .999]ConclusionsAltogether, these results support the efficacy of psychological interventions aimed at preventing unintended pregnancy through contraception.
