Tocophobia in the DSM-5 era: Outcomes of a new cut-off analysis of the Wijma delivery expectancy/experience questionnaire based on clinical presentation.

INTRODUCTION AND AIMS: Diagnosis of tocophobia using existing instruments is an area of active investigation. Although a range of Wijma Delivery Experience Questionnaire (W-DEQ) cut-off scores has been suggested for detecting tocophobia, there is no consensus among researchers about an optimal cut-off score. The primary goal of the present study was to identify a cut-off value while referring to the DSM-5 Specific Phobia criteria as a gold standard, and to accordingly evaluate how the fearful component of the childbirth experience and psychopathology in the post-natal period are affected by tocophobia.

METHODS: We conducted an observational, longitudinal study on nulliparous women (n = 106). Routine pregnancy data and data from psychometric questionnaires investigating depression, anxiety, and fear of childbirth were collected. A psychiatric Structured Clinical Interview for DSM-5 (SCID-5) was also conducted. The same parameters were re-evaluated one month after parturition.

RESULTS: A W-DEQ score of 85 was found to be the optimal cut-off score for detecting tocophobia, with sound sensitivity (100%) and specificity (93.8%). We found substantial agreement between the W-DEQ A and SCID-5 Specific Phobia Criteria (Cohen's Kappa coefficient, κ = 0.720).

CONCLUSIONS: A W-DEQ cut-off value of 85 is a reliable tool for detecting clinically relevant fear of childbirth according to the DSM-5 diagnosis of Specific Phobia. Therefore, accurate psychopathological investigation must be administered to women with W-DEQ scores greater than this cut-off score.
