CHIS 2011‐2012 update Beginning of CHIS as a “continuous survey” – with data collectedBeginning of CHIS as a continuous survey with data collected
continuously throughout the year for 24 months
CHIS still treats two years as data collection cycley y
Over 2 years, sample equals former biennial CHIS sample (~48K HHs)
Retain same questions through both years (with exceptions)
Public Use File release and updates to AskCHIS will occur after completion of a full, 2‐year CHIS cycle

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
CHIS 2011 2012 t tCHIS 2011‐2012 status CHIS 2011‐2012 data collection
Data collection started in June 2011
Plan to collect our full sample (target of 48K households) over a 24‐month period (24K per year; 2K per month)period (24K per year; 2K per month)
Accelerated data collection schedule (4K per month) for 2011 to make up for the first 6‐months, with a goal of 24K households collected in 2011

Questions continue through 2013 Does your school offer free drinking water to students during lunchtime?
[IF NEEDED SAY “By free, I mean water that you don’t have to pay for.”]
Does your school offer free drinking water to students at lunchtime from drinking fountains or faucets in the cafeteria or where students eat?
… offer free drinking water to students at lunchtime from water pitchers?
…From a spout or dispenser that is attached to the wall?
...From a large container of water with a spout, such as a water cooler?

CHIS t lCHIS teen sample CHIS teen sample is a unique and valuable resource
However, CHIS teen sample yield has declined over time
Teen sample yield declined by 30% between 2001 and 2009

CHIS t lCHIS teen sample Why has the teen sample yield declined?
Two principal components leading to the teen interview
Parent permission—short script read to parent that seeks their permission to interview teen directly; has declined 33% between 2001 and 2009
Teen assent and completion—if parent provides permission, teen assents to be interviewed and completes the teen interview; has declined 11%between 2001 and 2009

CHIS t lCHIS teen sample Why the steep reduction in parent permission for the teen y p p p
interview?
Conduct 4 focus groups with parents of teens from CHIS 2009 andConduct 4 focus groups with parents of teens from CHIS 2009 and CHIS 2011 (TCE sponsored)
Mix of parents who did and did not provide permission for the teen p p pinterview
3 focus groups in English and 1 in Spanish
Goal is to improve the permission scripts to increase the proportion of parents who provide permission, thereby increasing the teen yield
