Bottom Line: The study found that the C-LATCon II had a satisfactory content validity (item-level Content Validity Index (CVI) = 0.83-1, scale-level CVI/universal agreement = 0.89, and scale-level CVI/averaging calculation = 0.98), construct validity (four components extracted explained 56.66 % of the total variance), internal reliability (Cronbach's alpha of overall scale and four components was 0.78 and 0.66-0.84, respectively), and test-retest reliability (Pearson's correlation coefficient = 0.82, p < 0.001; interclass correlation coefficient = 0.82, p < 0.001; linear weighted kappa statistic for each item = 0.40-0.65, p < 0.05).The C-LATCon II is a validated and reliable instrument which can be used to evaluate the attitudes to concordance in Chinese populations.Four components (health professionals' attitudes, partnership between two parties, therapeutic decision making, and patients' involvement) describe the attitudes towards concordance during health communication.

ABSTRACT

Background: Concordance is characterised as a negotiation-like health communication approach based on an equal and collaborative partnership between patients and health professionals. The Leeds Attitudes to Concordance II (LATCon II) scale was developed to measure the attitudes towards concordance. The purpose of this study was to translate the LATCon II into Chinese and psychometrically test the Chinese version of LATCon II (C-LATCon II).

Methods: The study involved three phases: i) translation and cross-cultural adaptation; ii) pilot study; and iii) a cross-sectional survey (n = 366). Systematic random sampling was used to recruit hypertensive patients from nine communities covering around 78,000 residents in China. Tests of psychometric properties included content validity, construct validity, criteria-related validity (correlation between the C-LATCon II and the Therapeutic Adherence Scale for Hypertensive Patients (TASHP)), internal reliability, and test-retest reliability (n = 30).

Results: The study found that the C-LATCon II had a satisfactory content validity (item-level Content Validity Index (CVI) = 0.83-1, scale-level CVI/universal agreement = 0.89, and scale-level CVI/averaging calculation = 0.98), construct validity (four components extracted explained 56.66 % of the total variance), internal reliability (Cronbach's alpha of overall scale and four components was 0.78 and 0.66-0.84, respectively), and test-retest reliability (Pearson's correlation coefficient = 0.82, p < 0.001; interclass correlation coefficient = 0.82, p < 0.001; linear weighted kappa statistic for each item = 0.40-0.65, p < 0.05). Criteria-related validity showed a weak association (Pearson's correlation coefficient = 0.11, p < 0.05) between patients' attitudes towards concordance during health communication and their health behaviours for hypertension management.

Conclusions: The C-LATCon II is a validated and reliable instrument which can be used to evaluate the attitudes to concordance in Chinese populations. Four components (health professionals' attitudes, partnership between two parties, therapeutic decision making, and patients' involvement) describe the attitudes towards concordance during health communication.

Fig2: Scree test

Mentions: The number of components was determined by combining three criteria: Cattell’s scree test, Kaiser’s eigenvalue-greater-than-one rule, and Horn’s parallel analysis [27]. The scree plot indicates that a sharp drop in the plot occurred between the third and fourth lines and therefore suggested a four-component extraction (Fig. 2). Four components had eigenvalues ≥ 1, which suggested that the number of components extracted was four (Table 2). According to the output of Monte Carlo PCA for parallel analysis, the Component 3 was considered significant because the eigenvalue (1.53) of the Component 3 was bigger than the 3rd random eigenvalue (1.27), whilst the Component 4 was considered insignificant because the eigenvalue (1.00) of the Component 4 was smaller than the 4th random eigenvalue (1.22) (Table 2). Although the scree plot, eigenvalue rule and parallel analysis provided inconsistent results of the number of components to be extracted, four components were identified after considering that the components extracted should reasonably interpret the items. These components accounted for more than 56 % of the total variance (Table 2).Fig. 2
