Self-Care Behaviors in Osteoporosis: A Cross-Cultural Study Using Multidimensional Analysis of Textual Data

Osteoporosis is a chronic skeletal condition that significantly affects daily life and may benefit from adequate self-care. The Middle-Range Theory of Self-Care of Chronic Illness conceptualizes self-care as a naturalistic process encompassing maintenance, monitoring, and management, also shaped by contextual and cultural factors. Despite this theoretical framework, limited evidence exists on how people with osteoporosis conceptualize and enact self-care in different cultural contexts. Italy and Spain provide comparable yet distinct settings for exploring cultural influences on self-care practices. This study aims to explore and compare self-care behaviors among Italian and Spanish people with osteoporosis.

A cross-national qualitative study was conducted using an Automatic Analysis of Textual Data approach within the Exploratory Multidimensional Data Analysis framework.

Forty people with osteoporosis (38 women and 2 men; mean age 68.6 years, SD = 5.74) were recruited, equally distributed between Italy (n = 20) and Spain (n = 20). Data were analyzed using Labbé's intertextual distance and correspondence analysis to examine lexical similarities, differences, and semantic structures of self-care narratives.

Although moderate intra-national lexical similarity was observed within each national group, substantial inter-national differences emerged between Italian and Spanish participants in the discursive construction of self-care. Italian participants described self-care as a medically mediated and system-oriented process, closely linked to professional guidance, diagnostic procedures, and prescribed treatments. In contrast, Spanish participants framed self-care as embodied, routine-based, and emotionally expressive, grounded in daily practices and bodily awareness. These findings indicate that participants relied on distinct cultural and epistemic models when interpreting and organizing self-care experiences.

This study highlights clear cross-cultural differences in how people with osteoporosis narrate and conceptualize self-care. Methodologically, it illustrates the potential of multidimensional analysis to support systematic and transparent comparison of qualitative datasets. The findings are consistent with the Middle-Range Theory of Self-Care and suggest that greater attention to cultural contexts may inform the development of self-care interventions that are more responsive to individuals' lived experiences.

Recognizing how cultural contexts influence how people with osteoporosis understand and practise self-care may help nurses tailor communication and educational support to individuals' everyday experiences, supporting more responsive and culturally sensitive care.
