[Assessment of "coping with disease" in patients with amyotrophic lateral sclerosis (ALS): on the use of an interviewer assessment rating scale].

Theories on "Coping" try to explain which resources people use to master crises and conflict situations. Reactions to challenges of life are considered as "coping strategies". In psychosomatic research, the notion of "coping" serves to describe how patients can handle physical or mental illness. Myatrophic (or amyothrophic) lateral sclerosis (ALS) is a rare chronic progressive disease of the nervous system with a gradual loss of motor neurons, resulting in muscular atrophy, weakness and spasticity. Since the etiology is unknown and no curative treatment available, most patients die from respiratory failure within a few years. In a follow-up study on physical disability, medical care and social support in 21 patients with advanced ALS, we tried to address the question how patients get along with such a threatening condition. After semi-standardized clinical interviews with patients and close relatives, two investigators gave independent descriptions of reported or observed "coping strategies" (rated as "not at all-barely-possibly-probably-very probably present"). Considering 17 patients assessed by both raters, significant agreement (Kendall's W) was achieved in three patients only. A comparison of aggregated answers (chi 2-Test) revealed different response sets, since one rater tended to choose extreme scale points, while the other preferred undecided answers. Differences of mean scores were observed in 8 out of 21 items, while significant correlations between investigators were obtained in another 8, including, though, only 2 of those 5 items which both had rated as "probably present" in no less than 50% of the patient sample ("Dejection & Flight-Brooding-Keeping the Situation Open-Distraction-Self-Isolation").(ABSTRACT TRUNCATED AT 250 WORDS)
