Yes, you typically need permission to use the Occupational Stress Scale (OSS) developed by House, McMichael, Wells, Kaplan & Landerman in 1979. The OSS is a copyrighted instrument, and its use is subject to the permission of the copyright holder, which may be the original authors or the publisher of the scale.
Before using the OSS in your research or any other context, it's important to obtain proper authorization. This often involves contacting the copyright holder, explaining your intended use of the scale, and requesting permission to use it. Depending on the circumstances, there may be fees associated with obtaining permission to use copyrighted materials.
Using copyrighted materials without permission can infringe on the rights of the copyright holder and may have legal consequences. Therefore, it's essential to ensure that you have the appropriate permissions before using the Occupational Stress Scale or any other copyrighted instrument.
Thank you for your informative reply. I too was of the same thought. However, I am having great difficulties obtaining permission. I fear I may have to search for an alternative. All advice welcomed.
