We previously developed the Tilburg Pregnancy Distress Scale (TPDS). The aim of the current study was to further assess its test-retest reliability, internal consistency, and construct and concurrent validity in 1739 pregnant women. TPDS scores during pregnancy were highly inter-correlated (r ≥ .70), with similar findings for its Negative Affect and Partner Involvement subscales. Pregnancy and delivery worries varied in different subgroups of women regarding their obstetric history. Nullipara reported more pregnancy- and delivery-related worries at all trimesters of pregnancy. Women with previous pregnancy-related complications reported more pregnancy-related worries, and those with previous delivery-related problems reported more delivery-related worries than women without these problems in the past. The TPDS seems to be a valid and reliable instrument to assess pregnancy-specific distress.

How Data are Classified: Categorical Data
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...
