They include subjects like information about the programme, issues related to prevention, awareness building, rights of disabled persons, services available for disabled persons and so on. Such information is often disseminated in a random manner using handouts, newsletters and other audio-visual methods, without planning or periodic monitoring. The information dissemination process can be made more effective if sound planning precedes the process, and if there is regular monitoring.
Dissemination is a process that has measurable components and leads to planned results.
In most cases, dissemination can be concretely measured. However, the time frame for measurement may require a prolonged period depending upon the exact nature of the desired impact. Many times, the evaluation of dissemination never goes beyond counting of numbers of pieces of paper, numbers of contacts, or numbers of responses received. This is because the counts are the easiest to carry out. Even though counts can provide some valuable information, the measure of impact on intended audiences requires a broader analysis than simple counting exercises.
