Aim: Cleft lip and palate (CLP) in children might impact their parents’ mental health. The pathology may cause burden in the parents’ life, primarily in the financial and social aspects. The IOFS (Impact on Family Scale) questionnaire, with 33 items and 4 aspects, measures the quality of life by quantifying the impact on families of chronic childhood conditions. This cross-sectional study was conducted to assess the validity and reliability of the IOFS. Materials and Methods: The translation of the IOFS questionnaire to Indonesian language was conducted by two translators. Thirty respondents based in three regions in East Nusa Tenggara (Kupang, Bima, and Selong) were selected for data collection. The scoring was measured using a Likert scale, and then the data were tested by Pearson’s bivariate test and Cronbach’s alpha test to assess the questionnaire’s validity and reliability, respectively. Results: A total of 31 statements showed validity scaling using the coefficient Pearson’s correlation >0.361 (P < 0.05) and 29 statements showed reliable scaling (Cronbach’s alpha) >0.60 (P < 0.05). The overall validity and reliability test revealed 27 valid and reliable IOFS instrument statements. Conclusion: The majority of the statements were valid and reliable. Thus, the IOFS instrument can be considered a reliable, valid, and straightforward tool to assess the burden on the cleft and lip palate family in Indonesia.
