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.

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.
