Anxiety levels in women undergoing prenatal maternal serum screening for Down syndrome: the effect of a fast reporting system by mobile phone short-message service.
To study the effect of fast reporting by mobile phone short-message service (SMS) on anxiety levels in women undergoing prenatal biochemical screening for Down syndrome.
                From January 2005 to December 2006, 2782 women undergoing prenatal biochemical serum screening were randomized into fast reporting by SMS (group A) or without mobile phone reporting (group B). Anxiety levels were measured with the Spielberger State-Trait Anxiety Inventory (STAI) before prenatal screen testing, before the appointed clinic (when the SMS report had already been given to group A), and 3 days after the appointed clinic (when the full screening report had been given to groups A and B).
                For screen-negative women, anxiety scores did not differ between groups before prenatal screen testing and 3 days after the appointed clinic. The state-anxiety scores measured on the second occasion had declined significantly in group A. The state-anxiety scores in both groups increased over the 3-week period after being informed of positive screen results. The trait- and state-anxiety scores at all points did not differ between the two groups of screen-positive women.
                The provision of a routine reporting system plus additional SMS report revealed some overall benefits in reducing anxiety among women with screen-negative result.

We found very limited evidence of low quality that communicating results of medical investigations by mobile phone messaging may make little or no difference to women's anxiety overall or in women with positive test results, but may reduce anxiety in women with negative test results. However, with only one study included in this review, this evidence is insufficient to inform recommendations at this time. More research is needed on the effectiveness and user evaluation of these interventions. In particular, more research should be conducted into the potential risks and limitations of these interventions.
