“…6,7,8,22,23 The PDQ total score reported in this sample was similar to previously reported findings 6,8,22 and lower than the means in two studies, by approximately 5- 16 points. 7,23 The results of this analysis support the internal consistency reliability of the PDQ total scale.…”

“…The finding that as perceived deficits increase so do feelings of depression, is consistent with other studies, 4,6,7,8 suggesting that self-reported cognitive difficulties are related to depressive symptoms. Importantly, these are correlations that demonstrate associations not causality.…”

“…The relationship found between self efficacy and PDQ support similar findings recently presented by Strober et al 6 and Schmitt et al 7 that self efficacy significantly predicted perceived cognitive functioning (measured by the PDQ) after controlling for depressive symptoms. The largest correlations found in this study were between the PDQ and the PROMIS Cognitive Abilities scale, suggesting that a person’s general perceived capabilities are associated with their cognitive complaints and may be important factors to consider when designing interventions to bolster cognitive abilities in persons with MS. We also found that greater use of memory strategies were related to greater perceived deficits.…”

“…6, 23, 25 Some might therefore conclude that self-reports are not a valid representation of cognition. It is more likely, however, that these two types of measures capture differing, or complementary, aspects of the complex phenomenon of cognition.…”

“…One instrument used to evaluate cognitive function is the Perceived Deficits Questionnaire (PDQ), part of a much larger instrument for those with MS. 11 Even though the PDQ has been used in a number of studies as an outcome variable, 4,6,7,8,9 limited work describes this measure or participants’ responses in more detail. The purpose of this study is to describe the nature and diversity of perceived cognitive deficits using the PDQ in a large community-based sample, to assess the reliability of the PDQ scale, and to explore self-reported predictors of PDQ scores in persons with MS.…”

Purpose To describe the nature and diversity of perceived cognitive deficits using the Perceived Deficits Questionnaire (PDQ), to assess the reliability of the PDQ, and to explore self-reported predictors of PDQ scores in a large community-based sample of persons with MS. Materials & Methods Persons with MS enrolled in a randomized controlled trial provided demographic data and completed the PDQ along with measures of cognitive and memory strategies, cognitive abilities, self-efficacy, and depressive symptoms, and neuropsychological tests. Results The majority of the 183 participants were non-Hispanic Caucasian women, approximately 49 years of age and diagnosed with MS 12.5 years prior. The most frequent cognitive complaints regarded trouble remembering phone numbers, mind drifting, and forgetting why one came into a room. PDQ scores were significantly related to self-rated cognitive abilities, depressive symptoms, self-efficacy, and use of cognitive strategies, but not to scores on neuropsychological performance tests. When controlling for other variables, self-rated cognitive abilities was the strongest, significant predictor of perceived cognitive deficits Conclusion Persons with MS most frequently experience deficits related to short term memory and attention. The PDQ total is a reliable measure of perceived cognitive deficits in persons with MS, is feasible for use by nurses in clinical settings—can be administered in approximately 5 minutes, and it is easily scored.

Perceived Cognitive Deficits in Patients With Symptomatic SARS-CoV-2 and Their Association With Post–COVID-19 Condition

ImportanceNeuropsychiatric symptoms are common in acute SARS-CoV-2 infection and in post–COVID-19 condition (PCC; colloquially known as long COVID), but the association between early presenting neuropsychiatric symptoms and PCC is unknown.ObjectiveTo describe the characteristics of patients with perceived cognitive deficits within the first 4 weeks of SARS-CoV-2 infection and the association of those deficits with PCC symptoms.Design, Setting, and ParticipantsThis prospective cohort study was conducted from April 2020 to February 2021, with follow-up of 60 to 90 days. The cohort consisted of adults enrolled in the University of California, Los Angeles, SARS-CoV-2 Ambulatory Program who had a laboratory-confirmed symptomatic SARS-CoV-2 infection and were either hospitalized in a University of California, Los Angeles, hospital or one of 20 local health care facilities, or were outpatients referred by a primary care clinician. Data analysis was performed from March 2022 to February 2023.ExposureLaboratory-confirmed SARS-CoV-2 infection.Main Outcomes and MeasuresPatients responded to surveys that included questions about perceived cognitive deficits modified from the Perceived Deficits Questionnaire, Fifth Edition, (ie, trouble being organized, trouble concentrating, and forgetfulness) and symptoms of PCC at 30, 60, and 90 days after hospital discharge or initial laboratory-confirmed infection of SARS-CoV-2. Perceived cognitive deficits were scored on a scale from 0 to 4. Development of PCC was determined by patient self-report of persistent symptoms 60 or 90 days after initial SARS-CoV-2 infection or hospital discharge.ResultsOf 1296 patients enrolled in the program, 766 (59.1%) (mean [SD] age, 60.0 [16.7] years; 399 men [52.1%]; 317 Hispanic/Latinx patients [41.4%]) completed the perceived cognitive deficit items at 30 days after hospital discharge or outpatient diagnosis. Of the 766 patients, 276 (36.1%) perceived a cognitive deficit, with 164 (21.4%) having a mean score of greater than 0 to 1.5 and 112 patients (14.6 %) having a mean score greater than 1.5. Prior cognitive difficulties (odds ratio [OR], 1.46; 95% CI, 1.16-1.83) and diagnosis of depressive disorder (OR, 1.51; 95% CI, 1.23-1.86) were associated with report of a perceived cognitive deficit. Patients reporting perceived cognitive deficits in the first 4 weeks of SARS-CoV-2 infection were more likely to report symptoms of PCC than those without perceived cognitive deficits (118 of 276 patients [42.8%] vs 105 of 490 patients [21.4%]; χ21, 38.9; P &lt; .001). Adjusting for demographic and clinical factors, perceived cognitive deficits in the first 4 weeks of SARS-CoV-2 were associated with PCC symptoms (patients with a cognitive deficit score of &gt;0 to 1.5: OR, 2.42; 95% CI, 1.62-3.60; patients with cognitive deficit score &gt;1.5: OR, 2.97; 95% CI, 1.86-4.75) compared to patients who reported no perceived cognitive deficits.Conclusions and RelevanceThese findings suggest that patient-reported perceived cognitive deficits in the first 4 weeks of SARS-CoV-2 infection are associated with PCC symptoms and that there may be an affective component to PCC in some patients. The underlying reasons for PCC merit additional exploration.
