CHIS 2011 12 C ll Ph d i hi hli htCHIS 2011‐12 Cell Phone design highlights Major increase in the cell phone sample (from about 7% in CHIS 

2009 to 20% in CHIS 2011‐2012)

Adds significantly to data collection cost, as cell phone sampled b t 35% i th l dlicases are about 35% more expensive than landline cases

Reimbursement for minutes of air time

Cell phones must be manually dialed per FCC regulations Cell phones must be manually dialed per FCC regulations

Increase in cell sample important for several reasons:

Reduce dependence on weights to adjust sample for populationReduce dependence on weights to adjust sample for population

Follows continuing trend of growing cell‐phone only households in the population – especially helpful in recruiting adolescents

Overcomes weighting difficulties sometimes encountered when combining landline and cell samples in medium and small counties
