Niger Postgrad Med J [serial online] 2015 [cited 2017 May 22];5-201. 2015/22/4/195/173959 These can be observational, self-report, interview and record review.The various measurements will ultimately require measurement tools through which the values will be captured.The questionnaire was designed to measure the following constructs: child personal factors; parental support and self-efficacy for providing support; parental rules and restrictions; maternal attitudes and perceptions; maternal behaviour; barriers to physical activity; and the home and local environments. Study I included 24 mothers of four-year-old children who completed the questionnaire then participated in a telephone interview covering similar items to the questionnaire.To assess validity, the agreement between interview and questionnaire responses was assessed using Cohen's kappa and percentage agreement.One of the most common tasks often encountered in social science research is ascertaining the validity and reliability of a measurement tool.

This has been linked to the dearth of knowledge of these tests.
