Objective: To determine the validity and reliability of Incontinence Praying Ability (I-PA) among
Muslim childbearing-aged women. Methods: A cross sectional study was conducted among Muslim
women under childbearing age attended clinics in a university teaching hospital. Two measures were
used in the present study and there were I-PA and Incontinence Quality of Life (I-QoL). I-PA was
developed in Malay language and its construct validity had not been explored. The questionnaires
were handed to the Muslim women during their visit to the clinics in Hospital Universiti Sains
Malaysia. Exploratory Factor Analysis (EFA) was conducted to determine the construct validity
and the Cronbach’s alpha was used to examine the internal consistency reliability of I-PA. Pearson
correlation was used to examine the correlation between I-PA and the subscales of I-QoL. Validity was
further supported if both scales were significantly correlated. Results: A total of 162 Muslim women
completed and returned the questionnaires to the researchers. The mean age of participants was 32.4
(SD = 5.87). Based on EFA result, all the 10 items of I-PA were remained in the model under one
factor and no item deletion was required. The factor loadings were ranged from 0.70 to 0.91. The
internal consistency of I-PA was satisfactory with Cronbach’s Alpha of 0.94. There were significant
correlations between I-PA and I-QoL’s subscales, ranged from 0.64 to 0.71. Conclusion: I-PA was
considered a valid and reliable questionnaire measuring incontinence quality of life in the aspect of
praying ability or spirituality among Muslim childbearing-aged women.
