Psychometric properties of the multidimensional health locus of control scale form C in a non-Western culture.

ABSTRACT: Form C of the Multidimensional Health Locus of Control Scales (MHLC-C) was designed to investigate health-related control beliefs of persons with an existing medical condition. The aim of the present study was to examine the psychometric properties of this instrument in a culture characterized by external control beliefs and learned helplessness-contrary to the societal context of original test development. Altogether, 374 Hungarian patients with cancer, irritable bowel syndrome, diabetes, and cardiovascular and musculoskeletal disorders were enrolled in the study. Besides the MHLC-C, instruments measuring general control beliefs, anxiety, depression, self-efficacy, and health behaviors were also administered to evaluate the validity of the scale. Both exploratory and confirmatory factor analytic techniques were used to investigate the factor structure of the scale. Our results showed that the Hungarian adaptation of the instrument had a slightly different structure than the one originally hypothesized: in the present sample, a three-factor structure emerged where the items of the Doctors and the Others subscales loaded onto a single common component. Internal reliability of all three subscales was adequate (alphas between .71 and .79). Data concerning the instrument's validity were comparable with previous results from Western countries. These findings may suggest that health locus of control can be construed very similarly to Western countries even in a post-communist society-regardless of the potential differences in general control beliefs.

Project description:BACKGROUND:Assessing the complexities of eating behaviors in patients who undergo bariatric surgery is challenging. The Eating Loss of Control Scale (ELOCS), a measure of loss-of-control (LOC) eating, has not yet been evaluated psychometrically among bariatric surgery patients. OBJECTIVE:This study presents a psychometric examination of the ELOCS in postoperative bariatric surgery patients. SETTING:Academic medical center in the United States. METHODS:One hundred seventy-one postbariatric treatment-seeking adults (82.5% female, 52.4% white) with LOC eating completed the ELOCS and measures assessing eating psychopathology and mood. Confirmatory factor analysis (CFA) was used to test fit for a 1-factor solution. Exploratory factor analysis (EFA) examined alternative factor structures. RESULTS:CFA revealed poor fit for a 1-factor structure (χ2 = 220.375, degrees of freedom = 135, P < .001, comparative fit index = .917, Tucker-Lewis index = .906, root mean square error of approximation = .067). EFA data suggested an alternative factor solution (χ2 = 157.76, degrees of freedom = 118, P = .009, comparative fit index = .965, Tucker-Lewis index = .955, root mean square error of approximation = .047). Factor 1 (α = .88) reflected behavioral aspects and factor 2 (α = .92) reflected cognitive/emotional aspects of LOC eating. Bivariate correlations with measures of eating and other psychopathology suggested good construct validity for factors. CONCLUSIONS:Findings suggest possible differences in the construct validity of the ELOCS among postbariatric patients. The 1-factor solution previously supported in clinical and nonclinical groups demonstrated poor fit. EFA revealed a possible alternative 2-factor solution that aligns with emerging literature, suggesting that LOC eating presents differently in postbariatric patients. Researchers interested in LOC eating among bariatric patients should consider use of the ELOCS and testing the proposed alternative factor structure.

Project description:BackgroundBladder cancer is a leading cause of death among Chinese male populations in recent years. The health locus of control construct can mediate health status and outcomes, and it has proven helpful in predicting and explaining specific health-related behaviors. However, it has never been used to investigate health beliefs about bladder cancer prevention and treatment.ObjectiveThis study aimed to classify male patients into different latent groups according to their beliefs about bladder cancer prevention and treatment and to identify associated factors to provide implications for the delivery of tailored education and interventions and the administration of targeted prevention and treatment.MethodsFirst, we designed a four-section questionnaire to solicit data: section 1-age, gender, and education; section 2-the communicative subscale of the All Aspects of Health Literacy Scale; section 3-the eHealth Literacy Scale; and section 4-health beliefs about bladder cancer prevention and treatment measured by the Multidimensional Health Locus of Control Scale Form C. We hypothesized that the participants' health beliefs about bladder cancer prevention and treatment measured in section 4 could be closely associated with information collected through sections 1 to 3. We recruited 718 Chinese male patients from Qilu Hospital of Shandong University, China, and invited them to participate in a web-based questionnaire survey. Finally, we used latent class analysis to identify subgroups of men based on their categorical responses to the items on the Multidimensional Health Locus of Control Scale Form C and ascertained factors contributing to the low self-efficacy group identified.ResultsWe identified 2 subgroups defined as low and moderate self-efficacy groups representing 75.8% (544/718) and 24.2% (174/718) of the total sample, respectively. Men in the low self-efficacy cluster (cluster 1: 544/718, 75.8%) were less likely to believe in their own capability or doctors' advice to achieve optimal outcomes in bladder cancer prevention and treatment. Men in the moderate self-efficacy cluster (cluster 2: 174/718, 24.2%) had distinct psychological traits. They had stronger beliefs in their own capability to manage their health with regard to bladder cancer prevention and treatment and moderate to high levels of trust in health and medical professionals and their advice to achieve better prevention and treatment outcomes. Four factors contributing to low self-efficacy were identified, including limited education (Year 6 to Year 12), aged ≥44 years, limited communicative health literacy, and limited digital health literacy.ConclusionsThis was the first study investigating beliefs about bladder cancer prevention and treatment among Chinese male patients. Given that bladder cancer represents a leading cause of death among Chinese male populations in recent years, the low self-efficacy cluster and associated contributing factors identified in this study can provide implications for clinical practice, health education, medical research, and health policy-making.
