ABSTRACT

Background: Self-efficacy is the individual’s assessment of his or hers ability to complete a specific task successfully and has been closely related to self-management and quality of life in several diseases. Objective: To investigate self-efficacy in a population of Parkinson’s disease (PD) patients in Mexico and study the factors that are associated with this measure. Methods: We carried out a cross-sectional observational study involving patients with PD in an outpatient neurology clinic in Mexico, using the following instruments: Spanish version of the Chronic Disease Self-Efficacy Scale (CDSES), Quality of Life Questionnaire PDQ-8, Movement Disorders Society-Unified Parkinson's disease Rating Scale (MDS-UPDRS), Montreal Cognitive Assessment (MoCA), and Non-Motor Symptom Scale (NMSS). Clinical and demographic variables were also recorded. Results: We included 73 patients with a mean age of 65 years and most patients were male. Patients with lower CDSES scores (<7.75) had worse scores in MDS-UPDRS, NMSS, and PDQ-8 scales. CDSES scores were significantly correlated with MDS-UPDRS Part I (r=-0.497, p=<0.001), Part II (r= -0.271, p=0.020), Part III (r=-0.304, p=<0.001), PDQ-8 (r=-0.472, p=<0.001), and NMSS (r=-0.504, p=<0.001). Furthermore, when assessing the simultaneous effect of covariates associated with CDSES score, only Mood/Apathy domain of NMSS was significant (beta= -0.446, t= -3.807, p= 0.012). Conclusions: PD patients with lower self-efficacy scores had worse motor and non-motor symptomatology and quality of life. Mood/Apathy disorders were negatively associated with self-efficacy and contributed significantly to this measure.

RESUMEN

Antecedentes: La autoeficacia es la autoevaluación de un individuo sobre su capacidad para completar una tarea con éxito y se ha relacionado con automanejo y calidad de vida en otras enfermedades. Objetivo: Investigar la autoeficacia en una población de pacientes con enfermedad de Parkinson (EP) en México y estudiar factores asociados con esta medida. Métodos: Realizamos un estudio observacional transversal con pacientes con EP en una clínica de neurología en México. Se registraron datos demográficos y escalas que evalúan la función motora (MDS-UPDRS), no motora (NMSS) y cognitiva (MoCA), así como la calidad de vida (PDQ-8). Para valorar autoeficacia se utilizó la versión en español de la Escala de autoeficacia de enfermedades crónicas (CDSES). Resultados: Se incluyeron 73 pacientes, con una edad media de 65 años y la mayoría eran hombres. Pacientes con puntajes CDSES más bajos (<7.75) tuvieron peores puntajes en las escalas MDS-UPDRS, NMSS y PDQ-8. Las puntuaciones de CDSES se correlacionaron significativamente con la escala MDS-UPDRS Parte I (r=-0.497, p=<0.001), Parte II (r= -0.271, p=0.020), Parte III (r=-0.304, p=<0.001), PDQ-8 (r= -0.472, p=<0.001), y NMSS (r=-0.504, p=<0.001). Al evaluar el efecto simultáneo de covariables asociadas con la escala CDSES, solo el dominio estado de ánimo/apatía del NMSS resultó significativo (Beta = -0.449, t = -3.783, p = <0.001). Conclusiones: Los pacientes con menores puntajes de autoeficacia tienen peor calidad de vida y sintomatología motora y no motora. Los trastornos del estado de ánimo contribuyen negativamente a la autoeficacia.
