title: Psychometric evaluation of patient assessment of chronic illness care among Korean cancer survivors

description: Background: The Patient Assessment of Chronic Illness Care (PACIC) was
 developed in the United States to assess the implementation of the Chronic
 Care Model (CCM)-based intervention from the patient’s perspective.
 Although the psychometric properties of the PACIC have been reported in
 other chronically ill patients, it has not been reported in cancer
 survivors. Our aim was to evaluate the acceptability, validity, and
 reliability of a Korean version of the PACIC among cancer survivors
 (K-PACIC-CS). Methods: Among 204 cancer survivors at a university-based
 hospital in South Korea, we performed psychometric evaluation of the
 K-PACIC-CS according to acceptability (descriptive statistics, missing
 values, and floor and ceiling effects), validity (confirmative factor
 analysis [CFA] and convergent validity), and reliability (internal
 consistency, i.e., Cronbach's alpha). Results: The item response was
 high (missing rate = 0.5%). The floor effect was 3.9%–43.6% and the
 ceiling effect was 6.9%–41.2%. The CFA revealed good indices of fit and
 confirmed the five structures predetermined in the original version of
 PACIC. The K-PACIC-CS scores had significant positive relationships with
 cancer survivors’ self-efficacy and health-related quality of life. The
 total K-PACIC-CS showed excellent internal consistency (Cronbach's
 alpha = .94) and those of the subscales were acceptable (Cronbach's
 alpha = .76-.86).  Conclusions: This study suggests that the
 K-PACIC-CS is a valid and reliable instrument for measuring implementation
 of CCM-based chronic care from the survivor’s perspective.
description: This study is a secondary analysis using data from a validation
 study of Cancer Survivors’ Self-Efficacy Scale (CSSES) among 204 patients
 who had completed their primary cancer treatment. Original data were
 collected after approval from the Institutional Review Board of Inha
 University Hospital (No. INHAUH-2017-04-025), and data access and analysis
 were additionally approved by the same institution for this study (No.
 INHAUH-2020-05-033). We recruited 204 study
 participants from a university-based hospital in Korea using the
 convenience sampling approach. Participants were: 1) at least 18 years
 old; 2) those diagnosed with any type of cancer and who had completed
 their primary treatment (surgery, chemotherapy, or radiation); and 3)
 those able to read and write Korean. Subjects with evidence of metastasis
 and/or recurrence, or those undergoing cancer treatment were
 excluded. Data were collected from June to July 2017 at
 an outpatient clinic at Inha University Hospital. Two trained researchers
 selected eligible patients by visiting potential enrollees in the
 outpatient department and checking their electronic medical records.
 During visits, the researchers explained the study, invited participation,
 and asked for consent to participate. After accepted participants
 voluntarily signed an informed consent form, the researchers distributed
 the questionnaire, which took about 20 minutes to complete. Detailed
 information about recruitment and procedures are described
 elsewhere.
