Patient adherence to their health care protocols is important to encourage the best health outcomes in rheumatoid arthritis (RA); however, little attention has been given to assessing the psychometric properties of adherence measures in this patient population. The purpose of this study was to evaluate the psychometric properties of three existing self-report measures of medication adherence in a sample of patients with RA—the Compliance-Questionnaire-Rheumatology (CQR), the Medication Adherence Report Scale (MARS), and the Medication Adherence Scale (MAS). A cross-sectional study of 108 clinic patients with rheumatoid arthritis was conducted to evaluate the reliability and validity of the measures. Cronbach’s alpha was .77 for both the CQR and a modified version of the MARS. For the MAS, the Kuder-Richardson 20 reliability was .25. Although not strong, test-retest reliability was adequate for all measures. Factor analysis indicated that both the MARS and the CQR measure two factors. All three instruments were moderately correlated with each other, with correlations ranging between .48 and .56. Although these scales were significantly correlated, moderate correlations among the scales indicate that they may not measure the same aspects of adherence. Among the three adherence measures, the modified MARS demonstrated the best evidence of reliability and validity and ease of administration in this sample of persons with RA.

Background. A new Lebanese scale measuring medication adherence considered socioeconomic and cultural factors not taken into account by the eight-item Morisky Medication Adherence Scale (MMAS-8). Objectives were to validate the new adherence scale and its prediction of hypertension control, compared to MMAS-8, and to assess adherence rates and factors. Methodology. A cross-sectional study, including 405 patients, was performed in outpatient cardiology clinics of three hospitals in Beirut. Blood pressure was measured, a questionnaire filled, and sodium intake estimated by a urine test. Logistic regression defined predictors of hypertension control and adherence. Results. 54.9% had controlled hypertension. 82.4% were adherent by the new scale, which showed good internal consistency, adequate questions (KMO coefficient = 0.743), and four factors. It predicted hypertension control (OR = 1.217; p value = 0.003), unlike MMAS-8, but the scores were correlated (ICC average measure = 0.651; p value < 0.001). Stress and smoking predicted nonadherence. Conclusion. This study elaborated a validated, practical, and useful tool measuring adherence to medications in Lebanese hypertensive patients.

Low medication adherence is one of the leading causes that affect the achievement of target levels for hypertension. Identifying modifiable factors associated with low adherence is crucial. This study aims to assess medication adherence and the role of beliefs about medicines on medication adherence among hypertensive patients.This cross-sectional study was conducted with 200 hypertension patients.Data were collected using the Morisky-Green-Levine Medication Adherence Scale, and the Beliefs about Medicines Questionnaire [BMQ-Turkish Translation (BMQ-T)]. It was found that the BMQ-T subscales of Specific Concern (β = 0.358, p = .027) and General Overuse (β = 0.552, p = .011) had an independent predictor effect on medication adherence scores. In this study, the patients who thought that drugs were overused and had concerns about this were seen to be less adherent with the medication. With regard to patients who use antihypertensive drugs but have uncontrolled blood pressure, their beliefs about drugs should not be ignored when evaluating adherence with drug therapy.

The present study aims to analyze the psychometric properties of the revised version of the Adolescent Cyber-Aggressor scale (CYB-AGS). This scale is composed of 18 items that measure direct and indirect cyberbullying. A cross-sectional study was conducted using two independent samples of adolescents. The first sample included 1318 adolescents (52.6% girls) from 12 to 16 years old (M = 13.89, SD = 1.32). The second sample included 1188 adolescents (48.5% boys) from 12 to 16 years old (M = 14.19, SD = 1.80). First, to study the psychometric properties of the CYB-AGS, exploratory factor analysis was performed on Sample 1. Results indicated a two-factor structure: direct cyber-aggression and indirect cyber-aggression. Second, to verify the structure of the CYB-AGS, we selected Sample 2 to conduct confirmatory factor analysis and test the scale’s convergent validity with theoretically-related measures. Results confirmed the reliability and validity of the two-dimensional model. Moreover, measurement invariance was established. Finally, regarding convergent validity, positive correlations were obtained between cyberbullying and aggressive behaviors in school, anger expression, negative attitudes towards school, and transgression of norms. Furthermore, negative correlations were found between cyberbullying and attitudes towards institutional authority.

Introduction. Antiepileptic drugs are effective in the treatment of epilepsy to the extent that about 70% of people with epilepsy can be seizure-free, but poor adherence to medication is major problem to sustained remission and functional restoration. The aim of this study was to assess the prevalence and associated factors of antiepileptic drug nonadherence. Methods. Cross-sectional study was conducted on 450 individuals who were selected by systematic random sampling method. Antiepileptic drug nonadherence was measured by Morisky Medication Adherence Scale (MMAS) and logistic regression was used to look for significant associations. Result. The prevalence of AEDs nonadherence was 37.8%. Being on treatment for 6 years and above [AOR = 3.47, 95% CI: 1.88, 6.40], payment for AEDs [AOR = 2.76, 95% CI: 1.73, 4.42], lack of health information [AOR = 2.20, 95% CI: 1.41,3.43], poor social support [AOR = 1.88, 95%, CI: 1.01, 3.50], perceived stigma [AOR = 2.27, 95% CI: 1.45, 3.56], and experience side effect [AOR = 1.70, 95% CI: 1.06, 2.72] were significantly associated with antiepileptic drug nonadherence. Conclusion. More than one-third of people with epilepsy were not compliant with their AEDs. Giving health information about epilepsy and its management and consequent reduction in stigma will help for medication adherence.

ObjectiveTo investigate the routine use of a measure of quality of life (QoL) in care homes and assess its psychometric properties when used by care staff.DesignA cross-sectional two-phase study.Setting and participantsData were collected from care staff in seven care homes in East Sussex, England.MethodPhase I: The ability of care staff from two care homes to use the DEMQOL-Proxy without interviewer administration was assessed using agreement analysis between a self-administered and interviewer-administered version of the instrument. Based on these findings, DEMQOL-Proxy was adapted into a new version, DEMQOL-CH, for use as a self-administered instrument in care homes. We assessed agreement between the new DEMQOL-CH and DEMQOL-Proxy to ensure DEMQOL-CH was used correctly. Phase II: A preliminary assessment of the psychometric properties of DEMQOL-CH when used routinely was completed in a further five care homes.ResultsPhase I: Nineteen care staff from two care homes completed QoL measurements for residents. Systematic error was identified when staff self-completed the DEMQOL-Proxy without an interviewer. We modified the DEMOoL-Proxy to create DEMQOL-CH; this reduced the error, producing a version that could be used more accurately by care staff. Phase II: Eleven care staff from five care homes rated resident QoL routinely. DEMQOL-CH showed acceptable psychometric properties with satisfactory reliability and validity and a clear factor structure.ConclusionsThe research presents positive preliminary data on the acceptability, feasibility and performance of routine QoL measurement in care homes using an adapted version of DEMQOL-Proxy, the DEMQOL-CH. Results provide evidence to support the concept that routine measurement of QoL may be possible in care homes. Research is needed to refine and test the methodology and instrument further and to explore the potential for benefits to residents, staff and care homes in larger and more representative populations.

ObjectiveThis analysis explored the association of treatment adherence with beliefs about medication, patient demographic and disease characteristics and medication types in rheumatoid arthritis (RA), psoriatic arthritis (PsA) or ankylosing spondylitis (AS) to develop adherence prediction models.MethodsThe population was a subset from ALIGN, a multicountry, cross-sectional, self-administered survey study in adult patients (n=7328) with six immune-mediated inflammatory diseases who were routinely receiving systemic therapy. Instruments included Beliefs about Medicines Questionnaire (BMQ) and 4-item Morisky Medication Adherence Scale (MMAS-4©), which was used to define adherence.ResultsA total of 3390 rheumatological patients were analysed (RA, n=1943; PsA, n=635; AS, n=812). Based on the strongest significant associations, the adherence prediction models included type of treatment, age, race (RA and AS) or disease duration (PsA) and medication beliefs (RA and PsA, BMQ-General Harm score; AS, BMQ-Specific Concerns score). The models had cross-validated areas under the receiver operating characteristic curve of 0.637 (RA), 0.641 (PsA) and 0.724 (AS). Predicted probabilities of full adherence (MMAS-4©=4) ranged from 5% to 96%. Adherence was highest for tumour necrosis factor inhibitors versus other treatments, older patients and those with low treatment harm beliefs or concerns. Adherence was higher in white patients with RA and AS and in patients with PsA with duration of disease <9 years.ConclusionsFor the first time, simple medication adherence prediction models for patients with RA, PsA and AS are available, which may help identify patients at high risk of non-adherence to systemic therapies.Trial registration numberACTRN12612000977875.

Abstract Background: Preschool educators who facilitate life skills health education have an important role. Limited research has explored the comprehensive content and strategies of courses related to health education in kindergarten. The aim of this study is to create a questionnaire scale suitable for assessing preschool educators' capacity for life skills health education in Taipei, Taiwan. Methods: A cross-sectional study design was used to explore and assess life skills health education as a teaching approach for preschool educators. The scale was developed in three steps. The first step was to create a draft questionnaire that passed a validation review by 9 experts. The second step was a pretest (N=128) with category analysis and exploratory factor analysis (EFA) to create the formal version of the scale. The dimension analysis of the scale to assess the life skills health education capacity of preschool educators in kindergartens included cognition, attitude and self-efficacy. The third step was official testing (N=503), in which the efficacy criterion correlation validity test showed good simultaneous validity and discrimination. Results: The first draft of the pretest analysis contained 45 initial questions; 38 questions remained after 7 questions were deleted based on the EFA. According to the theoretical framework and after deleting 8 items that did not conform to the standard, a total of 30 questions were included in the formal scale. The two factors in the cognitive subscale were "health-promoting kindergarten" and "life skills teaching" for a total of 9 questions, and the two factors in the attitude subscale were "perceived benefits" and "perceived barriers" for a total of 11 questions. The three factors of the self-efficacy subscale were "adaptability and self-management ability", "decision-making and critical thinking ability" and "communication and interpersonal communication ability" for a total of 10 questions. Cronbach's α coefficient for each subscale fell in the range of .813 to .936. Conclusions: This scale has satisfactory reliability and validity and can be administered to assess the outcomes of pedagogical training for life skills health education for preschool educators in health-promoting kindergartens.

Background and Purpose: The purpose of this study was to assess the psychometric properties of the Survey of Workplace Intimidation (SWI), including content and construct validity, factor structure, and internal consistency. Methods: A cross-sectional, descriptive study design was used for this study. The final sample consisted of 237 labor and delivery nurses who completed the SWI and the Practice Environment Scale of the Nursing Work Index (PES-NWI). Cronbach's alpha for the SWI was .930. Results: Content validity was obtained and the scale content validity index (S-CVI) was .943. Convergent validity was calculated by comparing the SWI with the PES-NWI, and the result was .408 (p .01). A factor analysis explained 61% of the variance and resulted in two factors: prescriber behaviors and nurses' responses to prescribers' behaviors. Conclusions: The SWI demonstrated acceptable reliability and validity.

Abstract Introduction Assessing adherence in schizophrenia facilitates interventions that optimize outcomes. Adherence rating questionnaires are feasible and non-intrusive; however, no validated measure exists in sub-Saharan Africa. We aimed to assess the psychometric properties of the 10-item Medication Adherence Rating Scale (MARS). Methods This was a cross-sectional study of a cohort of patients with schizophrenia (n=230). A sociodemographic questionnaire, the Mini International Neuropsychiatric Interview (MINI), Positive and Negative Syndrome Scale (PANSS), Scale for the Unawareness of Mental Disorder (SUMD) and the MARS were all administered by an interviewer. Results The MARS demonstrated good reliability (Cronbach’s alpha: 0.76). The scale was reducible to a 3-factor construct (1 – medication adherence behavior, 2 – attitude to taking medications, and 3 – negative side effects and attitude to psychotropics), with significant though weak external validity in relation to psychopathology (p<0.001) and insight (p<0.001). The first factor showed good internal consistency (α=0.80), comprising six items that could serve as a reliable proxy measure of adherence in place of the MARS Conclusion The MARS demonstrated fair psychometric characteristics in assessing adherence in patients with schizophrenia in this cohort. The scale may be useful in the dimensional assessment of medication adherence for schizophrenia in sub-Saharan African settings.
