Designing and Psychometric Evaluation of Breast Self-Examination Behavior Predicting Scale (BSEBPS)

Design and validation of a Questionnaire on the factors influencing self-care behaviors in patients with Multiple sclerosis (QFASMS)

BACKGROUND

Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease of the central nervous system (CNS). Since MS does not have a definitive cure, individuals affected by it need to adapt and coordinate with their chronic illness in order to fulfill their duties and responsibilities. The first step in helping patients to better care for and manage their illness is to engage in self-care behaviors. This study was conducted with the aim of design and validation of a questionnaire on the factors influencing self-care behaviors in patients with Multiple sclerosis.

METHODS

This cross-sectional study was conducted on Multiple sclerosis patients in Iran in 2023. The age range of patients varied between 22 and 52 years. Having MS disease, passing one year of the disease duration, living in Mashhad city, having informed consent to participate in the study and not completing the questionnaire were the entry and exit criteria of the study.

RESULTS

This study was conducted on 500 patients with multiple sclerosis. Based on the results of psychometrics (face, content and construct validity), the number of questions was reduced from 120 to 47 questions and 73 questions were eliminated. Finally, the questionnaire was approved with 47 questions and 4 subscales of understanding the symptoms of the disease (9 questions), tendency to conscious and targeted care (21 questions), laziness in care (8 questions) and tendency to receive therapy services (9 questions). Cronbach's alpha and McDonald's omega index for all questionnaire questions were 0.877 and 0.881, respectively.

CONCLUSIONS

Based on the results of this questionnaire, 47 questions and 4 subscales can be used to measure the factors influencing the adoption of self-care behaviour's in patients with multiple sclerosis.

Design and Psychometric Evaluation of Mammography Behavior Predicting Scale (MBPS)

Background: Breast cancer disease is an important public health trouble in the world. Over the past 2 decades, incidences of breast cancer among Iranian women have shown an alarmingly rapid increase. Mammography screening can lead to early detection and management of breast cancer and it also plays an important preventive role in decreasing breast cancer, especially among women over 40 years old. Objectives: This paper aims at reporting the psychometric properties of a questionnaire on mammography behavior based on health action process approach (HAPA) model. Methods: This cross-sectional study was performed between May and September 2017, and was attended by 400 women aged 40 years and older, in comprehensive health service centers in Iran. The research subjects were selected by multi-stage cluster sampling. The instrument was designed basis on the constructs of HAPA and current literature. The scale’s psychometric properties were examined by exploratory factor analysis (EFA), infraclass correlation coefficient (ICC), and Cronbach’s alpha. Results: The results showed 45 items of the questionnaire, 41 items had important item-to-total correlations (P < 0.05), and they were placed in 8 factors that contributed 60.88% of the scale variance. Conclusions: The research findings contribute to the reliability and validity of the HAPA model for predictively evaluating mammography goals.
