“…The OKAT was chosen to assess the recruits’ knowledge of osteoporosis as it was (a) a validated tool with good internal consistency (Cronbach’s alpha of .69), (b) designed to include the younger age-group of 25 to 44 years, and (c) suitable for self-administration by the respondents (Winzenberg, Oldenburg, Frendin, & Jones, 2003). It had been used by other studies on bone health (Long, Thiny, Sandler, & Gangarosa, 2010; Ryder, Kessler, Jones, & Shorr, 2007). OKAT consists of 20 questions of which six are gender-specific (e.g., Question 18 on bone loss after menopause).…”
