Abstract
ObjectiveApproximately half of all people living with amyotrophic lateral sclerosis (ALS) experience persistent or recurrent emotional distress, yet little is known about the psychological processes that maintain emotional distress in this population. The self-regulatory executive functioning (S-REF) model specifies that maladaptive metacognitive beliefs and processes are central to the development and maintenance of emotional distress. This study explored whether maladaptive metacognitive beliefs are associated with emotional distress after controlling for demographic factors, time since diagnosis, and current level of physical functioning.DesignIn a cross-sectional design, 75 adults with a diagnosis of ALS completed self-report questionnaires. Participants had a mean age of 60.40 years, mean duration of symptoms 63.92 months, and male:female gender ratio of 14:11.Main Outcome MeasuresQuestionnaires assessed emotional distress (HADS, adapted for ALS), physical functioning (ALSFRS-R), repetitive negative thinking (RTQ-10), metacognitive beliefs (MCQ-30), and demographic factors.ResultsMaladaptive metacognitive beliefs explained additional variance in emotional distress after controlling for age, gender, time since diagnosis, physical functioning, and repetitive negative thinking. Repetitive negative thinking partially mediated the relationships between positive and negative metacognitive beliefs and emotional distress.ConclusionsThese data support the utility of the metacognitive model in understanding emotional distress in people with ALS. Examination of the temporal relationship between maladaptive metacognitive beliefs and emotional distress in people living with ALS may help to guide the development of therapeutic approaches.
Highlights
Amyotrophic lateral sclerosis (ALS) is a progressive, incurable neurodegenerative disorder affecting the motor neurones (Brooks et al, 2000)
A model and associated intervention which focuses on how and why people respond to negative thoughts, such as those captured by illness perceptions, may be more useful for understanding distress experienced by people with ALS
As a first step toward developing more efficacious interventions for people with ALS, this study investigates the relationships between metacognitive beliefs, repetitive negative thinking and anxiety and depression in people with ALS
