Physical health after childbirth and maternal depression in the first 12 months post partum: Results of an Australian nulliparous pregnancy cohort study

Differentiating maternal fatigue and depressive symptoms at six months and four years post partum: Considerations for assessment, diagnosis and intervention

OBJECTIVE

fatigue and depressive symptoms are common among women in the postpartum period, and it has been proposed that fatigue is a risk factor for later depression. To progress this research, there is a need to clarify the conceptual and measurement issue of whether these two sets of symptoms are distinct constructs. There is also a need to determine whether they are distinct constructs beyond the postnatal period. The aim of the study was to assess the construct and discriminant validity of fatigue and depressive symptoms as measured by the SF-36 Vitality subscale (SF-36) and the Edinburgh Postnatal Depression Scale (EPDS) at six months and at four years post partum.

DESIGN, SETTING AND PARTICIPANTS

data from over 1000 women participating in the Maternal Health Study, a longitudinal study of women׳s physical and psychological health and recovery after childbirth were used.

FINDINGS

confirmatory factor analysis revealed a two-factor model of fatigue and depressive symptoms represented as distinct but related constructs was a better fit to the data than a one-factor model of fatigue and depression sharing the same underlying construct at both six months and four years post partum.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

this study provides empirical evidence that maternal fatigue and depression in the first year after having a baby and at four years post partum are best understood as separate psychological constructs or experiences. The findings have important implications for clinical practice, in particular underlining the importance of differentiating tiredness from depression.

Translation and validation of the German version of the Mother-Generated Index and its application during the postnatal period

OBJECTIVE

the Mother-Generated Index (MGI) is a validated tool to assess postnatal quality of life. It is usually administered several weeks or months after birth and correlates with indices of post partum mood states and physical complaints. The instrument had not been translated into German before or validated for use among German-speaking women, nor have the results of the tool been assessed specifically for the administration directly after birth. This paper aims to describe the systematic translation process of the MGI into German and to assess the convergent validity of the German version of the instrument directly after birth and seven weeks post partum.

DESIGN

prospective two-stage survey.

SETTING

two rural hospitals in the south of Germany and in the north of Switzerland.

PARTICIPANTS

all women giving birth between 1st October and 15th December 2012 with sufficient knowledge of German and whose babies were not referred to a neonatal care unit; 226 women were eligible to participate.

MEASUREMENT INSTRUMENTS

two questionnaires including questions relating to socio-demographic factors and perinatal care, and incorporating the MGI, the Hospital Anxiety and Depression Scale (HADS) and the Postnatal Morbidity Index (PMI). All instruments were subjected to forward and back translation and pilot-tested; the first questionnaire was then administered in the first two days after birth and the second six weeks post partum. Parametric and non-parametric tests were computed using SPSS.

FINDINGS

129 surveys were returned an average of three days after birth and 83 after seven weeks. Higher postnatal quality of life showed a significant correlation with a lower anxiety and depression score (p<0.01), fewer maternal physical complaints (p<0.05) and more favourable baby adjective scores (p<0.05) after birth. Significant associations were found between MGI scores and sufficient help (p=0.03) as well as ability to cope at home (p<0.01). MGI scores three days and seven weeks after birth correlated highly significantly and positively (p<0.001).

KEY CONCLUSIONS

convergent validity of the MGI with the HADS and the PMI suggests that the German version of the MGI is a valid indicator of physical and emotional post partum well-being.

IMPLICATION FOR PRACTICE

the German version of the MGI can be used in the post partum period to identify women whose quality of life is impaired during the first days after birth, in order to initiate extended midwifery care and referral if necessary.
