Objective:

To determine the construct validity and internal consistency of the instrument Self-Care of Hypertension Inventory (SC-HI v.2.0) translated into Spanish in Colombian adults with arterial hypertension.

Materials and methods:

Methodological study in which translation, cultural adaptation and content validity were carried out through expert judgment. With a sample of 290 hypertensive individuals, construct validity was determined by exploratory (principal component analysis with Varimax rotation with Kaiser normalization) and confirmatory factor analysis (maximum likelihood analysis). Internal consistency was calculated through Cronbach's alpha coefficient.

Results:

The self-care maintenance scale resulted in a two-factor structure (accumulated variance 61%) with good fit (χ2 = 104.570; p = 0.000; RMSEA = 0.125; SRMR = 0.156; CFI = 0.856; NNFI = 0.767). Self-care management reported a bifactorial structure (accumulated variance 71%) with good fit (χ2 = 6.598; p = 0.582; RMSEA = 0.000; SRMR = 0.072; CFI = 1.000; NNFI = 1.032). Finally, confidence scale also resulted in a bifactorial structure (accumulated variance 82%) with good fit (χ2 = 94.991, p = 0.000; RMSEA = 0.194; SRMR = 0.106; CFI = 0.934; NNFI = 0.876). Cronbach's alpha for maintenance (0.64), management (0.70), and confidence (0.86) was acceptable.

Conclusions:

The SC-HI v.2.0 in Spanish has adequate psychometric properties. Therefore, its use is recommended in research studies aimed at measuring self-care in populations with similar characteristics to that addressed in this study.
