PTSD sufferers often have problems with remembering the past, but do they also have trouble remembering tasks to be completed in the future? We argue characteristics of PTSD-such as negative appraisals and maladaptive strategies-might contribute to biased reporting of prospective memory failures among PTSD sufferers-or people with severe PTSD symptoms-within a general population.
Mechanical Turk participants completed a questionnaire battery measuring self-report prospective memory, PTSD symptoms, negative appraisals and maladaptive strategies (e.g., suppression), and depression, anxiety and stress symptoms.
PTSD symptom severity positively correlated with self-report prospective memory failures (rs = .42-49). PTSD symptoms affected self-report prospective memory via their influence on negative appraisals and maladaptive strategies.
Our findings rely on self-report, therefore we do not know if this relationship generalizes to objective prospective memory tasks.
Our data provide preliminary evidence for a relationship between PTSD symptomatology and subjective prospective memory in the general population and suggest that the negative appraisals and maladaptive strategies that commonly accompany PTSD might underpin this relationship.
