Abstract
Introduction Assisted reproductive technologies are typically perceived by couples as being an emotional burden. The objective of the study "Positive Ausrichtung bei unerfülltem Kinderwunsch" [Positive adjustment in infertility] (PACI) is to examine the efficacy and acceptance of a smartphone-supported psychosocial intervention during infertility treatment. In this investigation, the early drop-out of study subjects from the study is of primary interest. The objective of the investigation was to find predictors for ending a psychological intervention prematurely. Materials and Methods There are data available from an eight-month randomised, controlled study in which 141 patients and their partners participated. Sociodemographic and fertility-related data were collected at the start of the study. The couples received the ScreenIVF questionnaire at two points in time. As part of a post-evaluation, a survey was conducted on the efficacy of the psychological online intervention. To analyse the data, a dyadic data structure was used in order to determine connections within the study subject couples between the selected stress indicators and the drop-out. In addition, a "risk score" as a possible predictor for the drop-out was tested. Results The descriptive observation of the sample indicates in this interim assessment that the study subjects recruited are less stressed patient couples. Actor-partner interdependence models indicate statistically significant connections between the stress indicators of anxiety, little social support and helplessness and an early drop-out. Conclusions The statistically significant effects found in this study with regard to the stress indicators in connection with drop-outs from psychosocial intervention studies indicate that it is advisable to continue to seek measures for people undergoing stressful medical treatments in order to motivate and support them and thus optimally utilise the opportunities of a medical treatment. The number of patients who endure their ART treatment may also increase as a result, which could lead in turn to increased patient satisfaction over the long term (and thus possibly to higher pregnancy rates).
