An evaluation of the ALSSQOL-SF in the Malaysian context through cognitive interviewing

Quality of life is an important goal of care for people living with amyotrophic lateral sclerosis (ALS) and their carers. The ALS Specific Quality of Life instrument Short Form (ALSSQOL-SF) has been translated and validated in various cultural contexts, however its utility in the Malaysian cultural context has not yet been evaluated. The quality of life of 21 patients with ALS was evaluated using the ALSSOL-SF in either the English version or translated to the Malay language.

Cognitive interviewing showed that patients mostly could not grasp the intended meaning of the items from the psycho-social and spiritual domains despite translation into the Malay language. There are limitations in adapting the ALSSQOL-SF for use in evaluation of QOL in Malaysian ALS patients. In the local setting a better understanding is needed about how aspects such as religion, intimacy and spiritual well-being are culturally reflected and expressed. Quality of life is especially important to people living with ALS. It includes feeling well physically, psychologically and spiritually terms but this may be difficult to measure in numbers.

The ALSSQOL-SF is a questionnaire designed to measure these problems and it has been shown to be well understood and useful in Northern America. In Malaysia like in many other countries however, people may have different cultural backgrounds which affect how they think about quality of life. This ...
