Suspicion About Suspicion Probes: Ways Forward.

Suspicion probes are the traditional tool employed to assess the extent to which participants suspect intentional misdirection or deception within the research context. A primary reason psychologists use deception in research settings is to prevent participants from altering their behavior in light of knowing what is being studied, which could undermine internal validity as well as threaten the generalizability of findings to the real world (i.e.

Diisocyanate and non-diisocyanate sensitizer-induced occupational asthma frequency during 2003 to 2007 in Ontario, Canada.

Objective: To investigate proportions and outcomes of isocyanate and other causes of occupational asthma (OA) claims in Ontario, Canada, 2003 to 2007.

Methods: New accepted workers' compensation claims for OA compensated by the Ontario Workplace Safety and Insurance Board were retrospectively reviewed.

Results: There were 112 allowed claims for OA-30 (26.

Impact of a cleaners' strike on compensation claims for asthma among teachers in Ontario.

Background: A review of Workplace Safety and Insurance Board (WSIB) claims in Ontario from 1998 to 2002 showed an unusual spike in the number of claims accepted for work-exacerbated asthma (WEA) in April 2001.

Objective: To identify the cause for the spike in the number of WSIB claims for WEA in April 2001.

Methods: File reviews were performed to identify the occupations of workers with claims accepted for WEA in April 2001 compared with claims during March and May 2001, and during the same months in 2000 and 2002.

Reduction in diisocyanate and non-diisocyanate sensitizer-induced occupational asthma in Ontario.

Objective: To investigate relative frequency and features of diisocyanate (ISO) and non-diisocyanate (N-ISO) allowed occupational asthma (OA) claims in Ontario, Canada, during a 5-year period (1998 to 2002).

Methods: Records were abstracted from the Ontario Workplace Safety and Insurance Board using methodology similar to our previous investigation that had identified 30 ISO and 30 N-ISO claims/yr during 1980 to 1993.

Results: There were 99 OA claims: 37 ISO (7.

Work-related asthma in health care in Ontario.

Background: The health of workers in health care has been neglected in the past. There are few reports regarding occupational asthma (OA) in this group, and work-exacerbated asthma (WEA) has rarely been considered.

Methods: We examined the frequency of claims for OA and WEA allowed by the compensation board in Ontario, Canada for which industry was coded as "health care" between 1998 and 2002, to determine the frequency of OA and WEA, causative agents, and occupations.
