Notably, patients with long COVID commonly report persistent cognitive impairments. Objectives: This study aims to adapt and evaluate the validity and reliability of the self-report assessment; the PRPP-Long COVID in Thai adults with long COVID. Materials and methods: The Perceive, Recall, Plan, and Perform-Long COVID (PRPP-Long COVID) was adapted from the perceive, recall, plan, and perform (PRPP) System of Task Analysis: Thai version. This self-report assessment is used to assess the deficits of information processing capacity in individuals recovering from COVID-19. The psychometric properties of the PRPP-Long COVID were investigated, including content validity, internal consistency, and intra-rater reliability. Thirty individuals aged between 21 and 59 years had previously tested positive for COVID-19 by RT-PCR or Antigen Test Kit (ATK) and had recovered at least three months before participating in this study. All of them had an education level of at least secondary school. The PRPP-Long COVID was sent to three experts to examine for the Index of Item Objective Congruence (IOC). After that, the revised version of the PRPP-Long COVID was distributed to the participants. They were given the Google form link submission in 2 rounds, seven days apart, to test intra-rater reliability. For data analysis, descriptive statistics were utilized to calculate demographic characteristics, while the Cronbach alpha coefficient and the Intra-class Correlation Coefficients (ICCs) were used to estimate the internal consistency and intra-rater reliability of the PRPP-Long COVID, respectively. Results: The IOC values for each question demonstrated a high level of agreement (IOC=0.67-1.00). The internal consistency of the 34 questions in the PRPP-Long COVID indicated a high level of reliability, with α=0.93. The intrarater reliability of the PRPP-Long COVID was moderate to good (ICC=0.55-0.88). Conclusion: The PRPP-Long COVID self-rated assessment has been determined to have acceptable validity and reliability.Health ProfessionsArticleSCOPUS10.12982/JAMS.2026.0522-s2.0-10503088928225396056
