“…As just one example, incontinence at day-care centers can promote the spread of infectious diseases (Berk & Friman, 1990). Yet, abundant experimental evidence indicates that with skills training urinary continence can be established and maintained effectively in diverse populations, including infants (Smeets, Lancioni, Paul, & Oliva, 1985), emotionally disturbed adolescents (e.g., Friman & Vollmer, 1995), severely handicapped individuals (Azrin & Foxx, 1971), and very old adults (Burgio et al, 1990). A popular cultural and commercial trend toward increased diaper usage, however, appears to promote convenience over continence by forestalling (e.g., in the young) or even forgoing (e.g., in the handicapped or very old) skills training (e.g., Goode, 1999;Lancaster, 1990).…”
