Health-related lost productive time (LPT): recall interval and bias in LPT estimates.

We examined the effect of interview characteristics (ie, recall interval, interview version) on estimates of health-related lost productive work time (LPT). Three versions of a telephone interview were administered using 7-day and 4-week recall periods. In a population-based survey, 7674 workers randomly were assigned to one of six interviews at contact; 615 participants received a follow-up interview.

Lost productive work time costs from health conditions in the United States: results from the American Productivity Audit.

The American Productivity Audit (APA) is a telephone survey of a random sample of 28,902 U.S. workers designed to quantify the impact of health conditions on work.

Lost productive time and cost due to common pain conditions in the US workforce.

Context: Common pain conditions appear to have an adverse effect on work, but no comprehensive estimates exist on the amount of productive time lost in the US workforce due to pain.

Objective: To measure lost productive time (absence and reduced performance due to common pain conditions) during a 2-week period.

Design And Setting: Cross-sectional study using survey data from the American Productivity Audit (a telephone survey that uses the Work and Health Interview) of working adults between August 1, 2001, and July 30, 2002.

Cost of lost productive work time among US workers with depression.

Context: Evidence consistently indicates that depression has adversely affected work productivity. Estimates of the cost impact in lost labor time in the US workforce, however, are scarce and dated.

Objective: To estimate the impact of depression on labor costs (ie, work absence and reduced performance while at work) in the US workforce.
