Subject:Re: Lifetime incidence of child maltreatment

I agree with you, Edward---"incidence" is often computed annually, but it can refer to any timeframe..

The period of time may be--often is--a year, but may be shorter or longer. For example, "lifetime incidence" would mean rate during a lifetime. Likewise, "incidence per ___" may be a short time, e.g., "the incidence of eyeblinks increased from 3.7 to 6.5 per minute."

So the common cold has a high incidence (most people will have a cold in during the year) but a low prevalence (far fewer have a cold at any given time). For maltreatment, a child would be included in the incidence and prevalence count upon initial detection and identification (i.e., during the year in which it occurred). Thereafter, s/he would be only in the prevalence count unless a new maltreatment event was detected. Chris On Mon, Mar 31, 2014 at 3:21 PM, Bruce Borkosky > wrote: is that prevalence or incidence?

When we look only at substantiations, the cumulative percentage is roughly 5%. I would note that these estimates are for the birth cohort overall - the rates are much higher when we stratify by various measures of SES. In terms of national estimates of substantiated maltreatment through age 17 - I collaborated on an analysis that is a forthcoming paper in JAMA Pediatrics. It is currently embargoed - but will be published online in June. Please feel free to email me directly at ehornste@usc.edu if you want copies of any of the CA papers.

We have determined a rate in the Early Head Start randomized sample (birth to approximately age 15) but we are interested in samples for comparison and can only find information on annual incidence.
