The Quality of Life Questionnaire for Physiological Pregnancy was translated into Urdu by using a forward-backward procedure.

The constructs were retained based on extracted communalities. Data was analysed using SPSS v 21.
Results: The Urdu version of the questionnaire exhibited acceptable test-retest alpha values of 0.780 and 0.812 at two-time points, with an overall value of 0.790. All items showed good stability with intraclass correlation coefficient values of >0.80. The Kaiser-Meyer-Olkin measure for factor analysis was 0.812. Barlett's Test of Sphericity was significant (p<0.05). Three factors explaining the variance were extracted and the loading values for all nine constructs were acceptable (>0.40). All items of the translated version were retained, proving the validity of the Urdu version of the questionnaire.
Conclusions: The translated version of Quality of Life Questionnaire for Physiological Pregnancy was found to be a valid and reliable instrument for the assessment of quality of life for pregnant women in regions where Urdu is the prime language of communication.
