Dinger  \nABSTRACT  \nThis study examined the reliability and validity of the National College Health Risk Behavior Survey (NCHRBS) vigorous physical activity (VPA), moderate physical activity (MPA), flexibility (FLEX), and muscular strength and/or endurance (MSE) questions. Twenty college students completed the four items twice during the same day. During the next 7 days they wore an accelerometer and a pedometer during all waking hours. They also recorded their daily activity in a log. At the end of the week, subjects completed the NCHRBS physical activity items again. The intraclass correlation coefficients ranged from .94–.99 for the four items. The vigorous item was highly correlated with log VPA (r=.82) and number of days with ≥20 minutes of VPA from the accelerometer (r=.60). The flexibility item was moderately correlated (r=.57) and the muscular strength and/or endurance item was highly correlated (r=.89) with corresponding log activities. The moderate item was highly correlated with log MPA (r=.66) and number of days with ≥30 minutes of MPA from the accelerometer (r=.61). In conclusion, the NCHRBS physical activity items have excellent test-retest reliability and validity indices similar to other self-report physical activity questions.  \nWhen young adults attend college, they gain increased control over their lifestylesand develop a foundation of behaviors that may last throughout their lives. Researchers have determined that physical inactivity increases with age and the most rapid increase occurs in late adolescence and early adulthood (Stephens, Jacobs, & White, 1985). Many young adults on college campuses are not meeting current physical activity recommendations (Centers for Disease Control and Prevention, 1997; Dinger, 1999; Dinger & Waigandt, 1997), and a substantial proportion are leading a sedentary lifestyle (Pinto & Marcus, 1995) . Because physical inactivity is a major risk factor for coronary heart disease and is also  \nassociated with increasing risk for adultonset diabetes, hypertension, colon cancer, osteoporosis, anxiety, and depression (Pateet al., 1995), it is important that we have valid and reliable physical activity assessment tools that are specific to the college student population.  \nIn many settings, surveys are the most appropriate measure of physical activity because they are simple, inexpensive, unobtrusive, and generally do not require much effort on the part of the respondent (Ainsworth, 2000) . A widely used survey with the college student population is the National College Health Risk Behavior Survey (NCHRBS) (Centers for Disease Control and Prevention, 1997) . The  \nNCHRBS is the college student version of the Youth Risk Behavior Survey (Kolbe, Kann, & Collins, 1993) . The NCHRBS was developed by the Centers for Disease Control and Prevention to assess health-risk behaviors that are often established during youth and extend into adulthood. Six behavior categories are assessed by the  \nMary K.
